    Before: TATEL, KATSAS, and RAO, Circuit Judges.
    Opinion for the Court filed PER CURIAM.
    Concurring opinion filed by Circuit Judge KATSAS.
    Concurring opinion filed by Circuit Judge RAO.
    Dissenting opinion filed by Circuit Judge TATEL.
    PER CURIAM: The Federal Death Penalty Act of 1994
    (FDPA) requires federal executions to be implemented “in the
    manner prescribed by the law of the State in which the sentence
    is imposed.” 
    18 U.S.C. § 3596
    (a). It is common ground that
    this provision requires the federal government to adhere at least
    to a State’s choice among execution methods such as hanging,
    electrocution, or lethal injection. The district court held that
    the FDPA also requires the federal government to follow all the
    subsidiary details set forth in state execution protocols—such
    as, in the case of lethal injection, the method of inserting an
    intravenous catheter. On that basis, the court preliminarily
    enjoined four federal executions.
    Each member of the panel takes a different view of what
    the FDPA requires. Because two of us believe that the district
    court misconstrued the FDPA, we vacate the preliminary
    injunction.

    I
    A
    On three different occasions, Congress has addressed the
    “manner” of implementing the death penalty for federal capital
    offenses. In the Crimes Act of 1790, the First Congress
    specified that “the manner of inflicting the punishment of
    death, shall be by hanging the person convicted by the neck
    until dead.” Crimes Act of 1790, ch. 9, § 33, 
    1 Stat. 112
    , 119.
    This provision governed federal executions for over 140 years.
    In 1937, Congress changed this rule to make the “manner”
    of federal executions follow state law. Specifically, Congress
    provided:
    The manner of inflicting the punishment of death
    shall be the manner prescribed by the laws of the
    State within which the sentence is imposed. The
    United States marshal charged with the execution of
    the sentence may use available State or local facilities
    and the services of an appropriate State or local
    official or employ some other person for such
    purpose …. If the laws of the State within which
    sentence is imposed make no provision for the
    infliction of the penalty of death, then the court shall
    designate some other State in which such sentence
    shall be executed in the manner prescribed by the
    laws thereof.
    An Act To Provide for the Manner of Inflicting the Punishment
    of Death, Pub. L. No. 75-156, 
    50 Stat. 304
     (1937). Congress
    repealed this provision in 1984, see Sentencing Reform Act of
    1984, Pub. L. No. 98-473, § 212, 
    98 Stat. 1987
    , but left intact
    the underlying capital offenses. Accordingly, federal law still
    4
    authorized the death penalty, but no federal statute specified
    how it would be carried out.
    To fill this gap, the Attorney General promulgated a 1993
    regulation titled “Implementation of Death Sentences in
    Federal Cases.” 
    58 Fed. Reg. 4898
    , 4901–02 (Jan. 19, 1993).
    It provides that, unless a court orders otherwise, the “method
    of execution” of a federal death sentence shall be “[b]y
    intravenous injection of a lethal substance or substances in a
    quantity sufficient to cause death, such substance or substances
    to be determined by the Director of the Federal Bureau of
    Prisons.” 
    28 C.F.R. § 26.3
    (a)(4) (2019). The regulation also
    addresses various other matters including the time and place of
    execution, when the prisoner must be notified of the execution,
    and who may attend it. 
    Id.
     §§ 26.3–26.5.
    Congress enacted the FDPA in 1994. Under the FDPA, as
    under the 1937 statute, the “manner” of implementing federal
    death sentences turns on state law. In pertinent part, the FDPA
    provides that a United States marshal
    shall supervise implementation of the sentence in the
    manner prescribed by the law of the State in which
    the sentence is imposed. If the law of the State does
    not provide for implementation of a sentence of
    death, the court shall designate another State, the law
    of which does provide for the implementation of a
    sentence of death, and the sentence shall be
    implemented in the latter State in the manner
    prescribed by such law.
    
    18 U.S.C. § 3596
    (a). The FDPA also provides that a marshal
    overseeing an execution “may use appropriate State or local
    facilities” and “may use the services of an appropriate State or
    local official.” 
    Id.
     § 3597(a).
    5
    B
    At various times since 2001, the Department of Justice has
    developed protocols setting forth the precise details for
    carrying out federal executions. One such protocol was
    adopted in 2004 and updated in 2019. As updated, the protocol
    “provides specific time related checklists for pre-execution,
    execution, and post execution procedures, as well as detailed
    procedures related to the execution process, command center
    operations, contingency planning, news media procedures, and
    handling stays, commutations and other delays.” App. 24.
    This 50-page document addresses, among other things,
    witnesses for the execution, the prisoner’s final meal and final
    statement, strapping the prisoner to the gurney, opening and
    closing the drapes to the execution chamber, injecting the lethal
    substances, and disposing of the prisoner’s body and property.
    For the three federal executions conducted between 2001
    and 2003, the Bureau of Prisons used a combination of three
    lethal substances—sodium thiopental, a barbiturate that
    “induces a deep, comalike unconsciousness when given in the
    amounts used for lethal injection,” Baze v. Rees, 
    553 U.S. 35
    ,
    44 (2008) (plurality opinion); pancuronium bromide, which
    stops breathing; and potassium chloride, which induces cardiac
    arrest.    None of the three prisoners challenged these
    procedures. In 2008, the Bureau memorialized its use of the
    three substances in an addendum to its 2004 execution
    protocol, and the Supreme Court held that Kentucky’s use of
    the same three substances for executions did not violate the
    Eighth Amendment, see 
    id. at 44, 63
    ; 
    id. at 94
     (Thomas, J.,
    concurring in judgment). But by 2011, a “practical obstacle”
    to using sodium thiopental had emerged, “as anti-death penalty
    advocates pressured pharmaceutical companies to refuse to
    supply the drug” for executions. Glossip v. Gross, 
    135 S. Ct. 2726
    , 2733 (2015).
    6
    The Bureau then explored the possible use of other lethal
    substances. Its personnel visited state execution sites and
    evaluated their protocols. BOP also consulted with medical
    experts, reviewed assessments of difficult executions, and
    studied relevant judicial decisions. It considered several
    options, including three-drug protocols using other
    barbiturates, three-drug protocols using weaker sedatives, and
    one-drug protocols.
    After extensive study, the Bureau recommended use of a
    single barbiturate—pentobarbital—to carry out federal
    executions. It noted that many recent state executions had used
    pentobarbital without difficulty and that courts repeatedly have
    upheld the constitutionality of its use for executions. Further,
    BOP had located a “viable source” for obtaining it. App. 15,
    19.
    For these reasons, the Bureau proposed a two-page
    addendum to its main execution protocol. The United States
    Marshals Service concurred in the proposal. On July 24, 2019,
    the Attorney General approved the addendum and directed the
    Bureau to adopt it. BOP did so the next day. This 2019
    addendum makes pentobarbital the sole lethal substance to be
    used in federal executions. The addendum also specifies
    procedural details such as dosage, identification of appropriate
    injection sites, and the number of backup syringes.
    C
    This appeal arises from several consolidated cases in
    which twelve death-row inmates challenge the federal
    execution protocol. The first of these cases was filed in 2005,
    by three inmates who are not parties to this appeal. With the
    government’s consent, the district court stayed their executions
    pending the decision in Hill v. McDonough, 
    547 U.S. 573
    (2006). The government subsequently requested that the case
    7
    be stayed pending the decision in Baze. With no objection from
    the inmates, the district court granted the request. In 2011, the
    government announced that it lacked the substances necessary
    to implement its execution protocol. From then through 2019,
    the consolidated cases were stayed, and the government
    submitted status reports explaining that its revision of the
    protocol was ongoing. During that time, one of the plaintiffs
    involved in this appeal—Alfred Bourgeois—filed a complaint
    challenging the unrevised protocol. On the parties’ joint
    motion, that lawsuit was stayed pending the revision.
    On July 25, 2019, the Department of Justice informed the
    district court that it had adopted a revised protocol providing
    for the use of pentobarbital. That same day, DOJ set execution
    dates for the four plaintiffs involved in this appeal: Daniel Lee,
    Wesley Purkey, Dustin Honken, and Bourgeois. Each of them
    moved for a preliminary injunction. Collectively, they claimed
    that the 2019 protocol and addendum violate the FDPA, the
    Administrative Procedure Act, the Federal Food, Drug, and
    Cosmetic Act, the Controlled Substances Act, and the First,
    Fifth, Sixth, and Eighth Amendments to the Constitution.
    On November 20, 2019, the district court issued a
    preliminary injunction prohibiting the government from
    executing any of the four plaintiffs. In re Fed. Bureau of
    Prisons’ Execution Protocol Cases, No. 1:19-mc-145, 
    2019 WL 6691814
     (D.D.C. Nov. 20, 2019). The court held that the
    plaintiffs were likely to succeed on the merits of their claim
    “that the 2019 Protocol exceeds statutory authority.” 
    Id. at *7
    .
    In particular, the court concluded that “the FDPA gives
    decision-making authority regarding ‘implementation’” of
    federal death sentences to states. 
    Id. at *4
    . Thus, “insofar as
    the 2019 Protocol creates a single implementation procedure it
    is not authorized by the FDPA.” 
    Id. at *7
    . The court reasoned
    that the requirement to conduct executions “in the manner
    8
    prescribed” by state law likely applies both to the selection of
    an execution method, such as lethal injection, and to
    “additional procedural details” such as the precise procedures
    for “how the intravenous catheter is to be inserted.” 
    Id. at *4, *6
    . The court did not address whether the plaintiffs were likely
    to succeed on their various other claims. The court further held
    that the balance of equities and the public interest favored a
    preliminary injunction. 
    Id. at *7
    .
    The government filed an interlocutory appeal under 
    28 U.S.C. § 1292
    (a)(1) and moved this Court immediately to stay
    or vacate the injunction. Without addressing the merits, we
    concluded that the motion did not meet “the stringent
    requirements for a stay pending appeal.” Order at 1, Roane v.
    Barr, No. 19-5322 (D.C. Cir. Dec. 2, 2019).
    The government applied to the Supreme Court for an
    emergency stay or vacatur of the preliminary injunction. The
    Court denied the application but directed us to decide the
    government’s appeal “with appropriate dispatch.” Barr v.
    Roane, 
    140 S. Ct. 353
     (2019 mem.). Three justices explained
    their view that the government was “very likely” to succeed on
    appeal. 
    Id.
     (statement of Alito, J.).
    We then ordered expedited briefing and argument on the
    government’s appeal.
    II
    A preliminary injunction is “an extraordinary remedy that
    may only be awarded upon a clear showing that the plaintiff is
    entitled to such relief.” Winter v. NRDC, 
    555 U.S. 7
    , 22 (2008).
    A party “seeking a preliminary injunction must establish that
    he is likely to succeed on the merits, that he is likely to suffer
    irreparable harm in the absence of preliminary relief, that the
    balance of equities tips in his favor, and that an injunction is in
    9
    the public interest.” 
    Id. at 20
    . On appeal, we review the district
    court’s legal conclusions de novo and its weighing of the four
    relevant factors for abuse of discretion. Abdullah v. Obama,
    
    753 F.3d 193
    , 197–98 (D.C. Cir. 2014).
    In reviewing a district court’s conclusion as to likelihood
    of success, “[t]here are occasions … when it is appropriate to
    proceed further and address the merits” directly. Munaf v.
    Geren, 
    553 U.S. 674
    , 689–92 (2008); see also Wrenn v. District
    of Columbia, 
    864 F.3d 650
    , 667 (D.C. Cir. 2017). For several
    reasons, we exercise our discretion to resolve the merits of
    plaintiffs’ primary FDPA claim. This claim is a purely legal
    one, which the parties have briefed thoroughly. At oral
    argument, the parties agreed that we should decide it now.
    Finally, assessing only the likelihood of success would invite
    further litigation and delays on remand, which would hardly
    constitute appropriate dispatch.
    The plaintiffs press two distinct claims under the FDPA.
    The first, on which the district court found they were likely to
    succeed, involves the requirement to implement federal
    executions in the manner provided by state law. As explained
    in separate opinions that follow, Judge Katsas and Judge Rao
    both reject that claim on the merits. Judge Katsas concludes
    that the FDPA regulates only the top-line choice among
    execution methods, such as the choice to use lethal injection
    instead of hanging or electrocution. Judge Rao concludes that
    the FDPA also requires the federal government to follow
    execution procedures set forth in state statutes and regulations,
    but not execution procedures set forth in less formal state
    execution protocols. Judge Rao further concludes that the
    federal protocol allows the federal government to depart from
    its procedures as necessary to conform to state statutes and
    regulations. On either of their views, the plaintiffs’ primary
    FDPA claim is without merit. Accordingly, the preliminary
    10
    injunction must be vacated, and judgment for the government
    must be entered on this claim.
    Alternatively, the plaintiffs contend that the federal
    protocol and addendum reflect an unlawful transfer of authority
    from the United States Marshals Service to the Federal Bureau
    of Prisons. The district court did not address this claim, but the
    plaintiffs press it as an alternative basis for affirmance, and
    both parties ask us to resolve it. A court has discretion to
    consider alternative grounds for affirmance resting on purely
    legal arguments. See, e.g., United States v. Anthem, Inc., 
    855 F.3d 345
    , 349 (D.C. Cir. 2017). And as noted above, in
    addressing likelihood of success on the merits, a court has
    discretion to decide the claim. Two of us address the
    alternative FDPA claim here. As explained in their separate
    opinions, Judge Katsas would reject the claim on the merits,
    and Judge Rao would hold that it was forfeited.
    The government also asks us to decide whether its protocol
    and addendum violate the notice-and-comment requirement of
    the Administrative Procedure Act. The district court did not
    reach that issue, and the plaintiffs urge us not to reach it. Judge
    Katsas and Judge Rao resolve the notice-and-comment claim
    because, on their view, it involves purely legal questions
    intertwined with the merits of the FDPA issues at the center of
    this appeal. On the merits, Judge Katsas and Judge Rao
    conclude that the 2019 protocol and addendum are rules of
    agency organization, procedure, or practice exempt from the
    APA’s requirements for notice-and-comment rulemaking.
    Judgment for the government must be entered on this claim.
    Finally, the government asks us to reject the plaintiffs’
    claims under the Food, Drug, and Cosmetic Act and the
    Controlled Substances Act. We decline to do so because those
    claims were neither addressed by the district court nor fully
    11
    briefed in this Court. We do share the government’s concern
    about further delay from multiple rounds of litigation. But the
    government did not seek immediate resolution of all the
    plaintiffs’ claims, including the constitutional claims and the
    claim that the protocol and addendum are arbitrary and
    capricious under the APA. Thus, regardless of our disposition,
    several claims would remain open on remand.
    III
    The Court vacates the preliminary injunction and remands
    the case to the district court for further proceedings consistent
    with this opinion. For the reasons given in his separate opinion,
    Judge Tatel dissents.
    So ordered.
    KATSAS, Circuit Judge, concurring:             The principal
    question in this appeal is what constitutes a “manner” of
    execution within the meaning of the Federal Death Penalty Act
    (FDPA). The government says that “manner” here means
    “method,” such that the FDPA regulates only the top-line
    choice among execution methods such as hanging,
    electrocution, or lethal injection. The plaintiffs, the district
    court, and Judge Tatel say that “manner” encompasses any
    state execution procedure, down to the level of how
    intravenous catheters are inserted. Judge Rao agrees, at least if
    the procedure is set forth in a state statute or regulation.
    In my view, the government is correct. The FDPA’s text,
    structure, and history show that “manner” refers only to the
    method of execution. Moreover, the federal execution protocol
    does not violate the FDPA by transferring authority from the
    United States Marshals Service to the Federal Bureau of
    Prisons. Furthermore, the protocol did not need to be
    promulgated through notice-and-comment rulemaking. For
    these reasons, I would vacate the preliminary injunction and
    remand the case with instructions to enter judgment for the
    government on the plaintiffs’ FDPA and notice-and-comment
    claims. Finally, apart from the merits, I would vacate the
    preliminary injunction because the balance of equities tips
    decidedly in favor of the government.
    I
    A
    The FDPA requires federal executions to be implemented
    “in the manner prescribed by the law of the State in which the
    sentence is imposed.” 
    18 U.S.C. § 3596
    (a). This appeal turns
    on the level of detail at which that provision operates. Does it
    cover the use of lethal injection rather than other execution
    methods such as hanging or electrocution? The selection of a
    lethal substance or substances? How much of the substance to
    2
    inject, and how many syringes to use for the injections? How
    many intravenous lines to insert, and where to insert them?
    Who should insert the lines? In modern execution practice,
    governments address such issues systematically and in advance
    of any execution. At the federal level, they are addressed by
    the FDPA, Department of Justice regulations, the federal
    execution protocol, and the protocol addendum. Likewise, at
    the state level, they are addressed in comparable detail by state
    statutes, regulations, and execution protocols.
    The government contends that the “manner” of execution
    regulated by the FDPA is simply the method or mode of
    execution—the top-line choice among mechanisms of fatality
    such as hanging, firing squad, electrocution, lethal gas, or lethal
    injection. Under that interpretation, the federal protocol is
    clearly consistent with the FDPA: Every state that authorizes
    capital punishment uses lethal injection “as the exclusive or
    primary means of implementing the death penalty.” Baze v.
    Rees, 
    553 U.S. 35
    , 42 (2008) (plurality opinion). The federal
    regulations likewise designate lethal injection as the means for
    implementing capital punishment, 
    28 C.F.R. § 26.3
    (a)(4), and
    the federal protocol establishes procedures for these injections.
    The district court and the plaintiffs read the FDPA much
    more broadly. According to the district court, the FDPA covers
    not only the method of execution but also “additional
    procedural details such as the substance to be injected or the
    safeguards taken during the injection.” In re Fed. Bureau of
    Prisons’ Execution Protocol Cases, No. 1:19-mc-145, 
    2019 WL 6691814
    , at *4 (D.D.C. Nov. 20, 2019). These “additional
    procedural details” include even provisions on “how the
    intravenous catheter is to be inserted.” See 
    id. at *6
    . As an
    example, the district court cited state protocol provisions
    requiring the catheter to be inserted by “medically trained”
    personnel, 
    id.
     at *6 n.6, whereas the federal protocol requires
    3
    the method of insertion to be determined based on “a
    recommendation from qualified personnel” or “the training and
    experience of personnel” on the execution team, App. 75. The
    plaintiffs largely embrace the district court’s position, though
    they seek to carve out exceptions for de minimis deviations
    from state procedures, as well as for procedures insufficiently
    related to implementation of the death sentence.
    1
    In my view, the government is correct. All indicators of the
    FDPA’s meaning—statutory text, history, context, and
    design—point to the same conclusion. The FDPA requires
    federal executions to follow the method of execution provided
    by the law of the state in which the sentence is imposed, but it
    does not require federal executions to follow the “additional
    procedural details” invoked by the district court.
    The district court began its analysis quite properly, by
    addressing the plain meaning of the critical word “manner.”
    The court recognized that the government’s position would be
    correct if the FDPA had addressed the “method” rather than the
    “manner” of execution, because the word “method” bears
    “particular meaning in the death penalty context”—i.e., it
    denotes the top-line choice among mechanisms of death such
    as hanging, electrocution, or lethal injection. In re Execution
    Protocol Cases, 
    2019 WL 6691814
    , at *4. But, the district
    court reasoned, “manner” is broader than “method” because
    one dictionary defines “manner” as “a mode of procedure or
    way of acting.” 
    Id.
     (quotation marks omitted). This analysis
    overlooks other definitions, as well as the need to consider
    statutory history and context, see, e.g., Nat’l Ass’n of Home
    Builders v. Defs. of Wildlife, 
    551 U.S. 644
    , 668–69 (2007);
    FDA v. Brown & Williamson Tobacco Corp., 
    529 U.S. 120
    ,
    132–33 (2000). Other dictionaries indicate that “manner” is
    4
    synonymous with “method” as well as “mode.” See, e.g.,
    Manner, Black’s Law Dictionary (6th ed. 1990) (“A way,
    mode, method of doing anything, or mode of proceeding in any
    case or situation.”). And history strongly indicates that, in the
    specific context of capital punishment, all three terms refer
    only to the top-line choice. This is reflected in practices and
    usages throughout American history.
    First, consider hanging. In 1790, the First Congress
    enacted a bill providing that “the manner of inflicting the
    punishment of death, shall be by hanging the person convicted
    by the neck until dead.” Crimes Act of 1790, ch. 9, § 33, 
    1 Stat. 112
    , 119. Congress thus described “hanging” as “the” unitary
    “manner” of imposing capital punishment, without undertaking
    to specify subsidiary details such as the length of the rope, how
    it would be fastened around the neck, or the training of the
    hangman. This approach followed the law of England, where
    one common form of capital punishment was to be “hanged by
    the neck till dead.” 4 W. Blackstone, Commentaries on the
    Laws of England 370 (1769). Blackstone further stated that a
    “sheriff cannot alter the manner of the execution by
    substituting one death for another,” for “even the king cannot
    change the punishment of the law, by altering the hanging or
    burning into beheading.” 
    Id.
     at 397–98 (emphasis added). This
    makes clear that hanging itself was considered a “manner” of
    execution, as distinct from burning or beheading. But no
    evidence suggests that the sheriff (or the king) could not
    improvise “procedural details” such as the length of the rope.
    In using “manner” to mean “method,” the First Congress
    followed common historical usage. See, e.g., 1 J. Ash, The New
    and Complete Dictionary of the English Language (2d ed.
    1795) (defining “manner” as “[a] form, a method”); 2
    S. Johnson, A Dictionary of the English Language (1755)
    (“Form; method.”). The use of hanging as “the manner” of
    5
    carrying out federal executions remained unchanged from 1790
    until 1937. During that time, no federal officials undertook to
    regulate its “procedural details.” And during much of that time,
    hanging “was virtually never questioned,” even though a rope
    too long could produce a beheading, while a rope too short
    could produce a prolonged death by suffocation. Bucklew v.
    Precythe, 
    139 S. Ct. 1112
    , 1124 (2019) (quotation marks
    omitted).1
    Consider also practices and usages with respect to the firing
    squad, another common method of execution into the 1800s.
    In Wilkerson v. Utah, 
    99 U.S. 130
     (1878), the Supreme Court
    held that the use of a firing squad for executions does not
    violate the Eighth Amendment. The statute at issue provided
    for “death by being shot, hung, or beheaded,” and the court
    imposed a sentence requiring that the defendant be “shot until
    … dead.” 
    Id.
     at 131–32 (quotation marks omitted). The
    legislature did not undertake to regulate subsidiary “procedural
    details” such as, in the case of a firing squad, the kind or
    number of guns, the type of ammunition, where the shooters
    would aim, or how far away they would stand. Nor did the
    sentencing court specify any of those details. And although
    such details might have affected the likelihood of unnecessary
    suffering during the execution, the Court never suggested that
    the Eighth Amendment claim turned on any of them. To the
    1
    Judge Rao seeks to downplay the Crimes Act of 1790 as merely
    reflecting usage “on a single occasion.” Post, at 19. But that statute
    governed “the manner” of conducting federal executions for 147
    years, and it is a direct predecessor of the FDPA provision at issue
    here. It is obviously central to the question presented. Judge Rao
    notes that section 13 of the Crimes Act of 1790 set forth different,
    more detailed “manners” of committing the offense of maiming. 
    Id. at 14
    . True enough, but the FDPA traces back to section 33 of the
    Act, which, in the specific context of executions, used “manner” to
    refer only to the top-line choice of method.
    6
    contrary, it surveyed various rules and customs on whether
    death sentences would be carried out “by shooting or hanging.”
    See 
    id.
     at 132–36. Moreover, it described the governing statute
    as addressing “the manner” of execution, 
    id. at 136
    , and it used
    the words “manner,” “method,” and “mode” interchangeably,
    see, e.g., 
    id. at 134
     (“shooting or hanging is the method”); 
    id. at 137
     (sentence “let him be hanged by the neck” addresses “the
    mode of execution” (quotation marks omitted)).
    The history of electrocution follows much the same pattern.
    Introduced in 1888, it soon became “the predominant mode of
    execution for nearly a century,” Baze, 
    553 U.S. at 42
     (plurality
    opinion), and the Supreme Court promptly upheld it as
    constitutional, In re Kemmler, 
    136 U.S. 436
     (1890). As
    Kemmler recounted, electrocution came to replace hanging
    because it was thought to be a more humane “manner” or
    “method” or “mode” of execution—terms the Court again used
    interchangeably. See 
    id.
     at 442–47. Moreover, the underlying
    legal and policy debates were framed as a unitary choice
    between hanging and electrocution, and the reformers never
    undertook to prescribe subsidiary “procedural details” such as
    how strong an electric current would be used, where electrodes
    would be attached, how the electric chair would be tested, or
    who would train the electrocutioner. See 
    id. at 444
    .2
    2
    Judge Rao highlights the Court’s statement that electrocution was
    painless when performed “in the manner contemplated by the [New
    York] statute.” Post, at 15; see Kemmler, 
    136 U.S. at
    443–44. Here
    is the key statutory provision, quoted in its entirety: “The
    punishment of death must, in every case, be inflicted by causing to
    pass through the body of the convict a current of electricity of
    sufficient intensity to cause death, and the application of such current
    must be continued until such convict is dead.” Ch. 489, Laws of the
    State of New York § 505 (June 4, 1888), quoted in Kemmler, 136
    7
    In sum, here is what a reasonably informed English speaker
    would have known as of 1937: For over 140 years, Congress
    had designated hanging as “the manner of inflicting the
    punishment of death” for federal capital sentences. English law
    likewise had described “hanging” as a permissible “manner” of
    executing a death sentence. “Manner” and “method” often
    were used interchangeably, including by the Supreme Court in
    assessing alternative execution methods such as hanging, firing
    squad, or electrocution. And nobody focused on subsidiary
    procedural details in the legal or policy debates over these
    various execution methods.
    The 1937 Act did not disturb this settled understanding
    about the “manner” of executing capital punishment. To the
    contrary, although Congress changed the governing rule, it
    preserved the underlying semantic understanding. Whereas the
    Crimes Act of 1790 had identified hanging as “the manner of
    inflicting the punishment of death,” 1 Stat. at 119, the 1937 Act
    provided a different rule for “[t]he manner of inflicting the
    punishment of death”—i.e., use “the manner prescribed by the
    laws of the State within which the sentence is imposed.” An
    Act To Provide for the Manner of Inflicting the Punishment of
    Death, Pub. L. No. 75-156, 
    50 Stat. 304
     (1937). Congress’s
    decision to carry forward the legally operative text—regarding
    “the manner of inflicting the punishment of death”—also
    carried forward the prevailing understanding about what
    constituted a “manner” of execution. The reason for this is the
    settled canon of construction, framed by Justice Frankfurter
    U.S. at 444–45. The statute thus required nothing more than
    electrocution. Judge Rao briefly notes other statutory details
    governing the timing, location, and witnesses of the execution. Post,
    at 16 n.9. They would have had no conceivable bearing on the
    painlessness of electrocution, and they were irrelevant to the one
    “manner” question that the Court framed, discussed, and decided—
    the unitary choice between electrocution and hanging.
    8
    and routinely applied since, that “if a word is obviously
    transplanted from another legal source, whether the common
    law or other legislation, it brings the old soil with it.”
    Frankfurter, Some Reflections on the Reading of Statutes, 
    47 Colum. L. Rev. 527
    , 537 (1947). See, e.g., Taggart v.
    Lorenzen, 
    139 S. Ct. 1795
    , 1801 (2019); Stokeling v. United
    States, 
    139 S. Ct. 544
    , 551 (2019); Hall v. Hall, 
    138 S. Ct. 1118
    , 1128 (2018).3
    3
    Judge Rao seeks to downplay this canon in contending that
    Congress’s usage in 1790 ought not matter much. She says that to
    maintain consistent usage of “manner” in successor statutes is to
    confuse the word’s abstract “sense,” which must remain fixed, with
    its concrete “reference,” which can evolve. Post, at 19–20. She
    bases this view on a law-review article that seeks to link originalism
    to the theory of proper names espoused by the philosopher Gottlob
    Frege, in pursuit of a “middle ground” between the interpretive
    approaches of Justice Scalia and Justice Stevens. Green, Originalism
    and the Sense-Reference Distinction, 
    50 St. Louis U. L.J. 555
    , 558
    (2006). Put aside the fact that leading philosophers hotly debate
    whether proper names even have a “sense” apart from their
    “reference.” See, e.g., S. Kripke, Naming and Necessity 22–70
    (1980). Put aside the fact that no Supreme Court Justice or opinion
    has adopted Professor Green’s account of how legal text is “partially
    living and partially dead.” Green, supra, at 559. Put aside the fact
    that, in my view, Justice Scalia was right that legal text has “a fixed
    meaning, which does not change.” A. Scalia, Scalia Speaks:
    Reflections on Law, Faith, and Life Well Lived 188 (E. Whelan &
    C. Scalia eds., 2017). Even on Professor Green’s account, the
    reference to a top-line execution method in the Crimes Act of 1790
    has significant interpretive weight in construing that statute (and its
    successors) over time. See Green, supra, at 560 (“While the framers
    are fallible regarding the reference of their [legal] language, they are
    still extremely useful guides.”). Thus, even accepting Professor
    Green’s theory, Judge Rao errs by failing to give substantial weight
    to how Congress used “manner” in the Crimes Act of 1790.
    9
    Likewise, the FDPA carried forward the relevant language
    and “old soil” from the 1937 Act. In fact, the statutes are
    virtually identical in all relevant respects. Both statutes provide
    for implementation of federal death sentences in the “manner”
    provided by state law. Compare 
    18 U.S.C. § 3596
    (a) (United
    States marshal “shall supervise implementation of the sentence
    in the manner prescribed by the law of the State in which the
    sentence is imposed”), with 50 Stat. at 304 (“The manner of
    inflicting the punishment of death shall be the manner
    prescribed by the laws of the State within which the sentence
    is imposed.”). Both statutes permit, but do not require, the use
    of state facilities for federal executions. Compare 
    18 U.S.C. § 3597
    (a) (“A United States marshal charged with supervising
    the implementation of a sentence of death may use appropriate
    State or local facilities for the purpose, may use the services of
    an appropriate State or local official or of a person such an
    official employs for the purpose, and shall pay the costs thereof
    in an amount approved by the Attorney General.”), with 50
    Stat. at 304 (“The United States marshal charged with
    execution of the sentence may use available State or local
    facilities and the services of an appropriate State or local
    official or employ some other person for such purpose, and pay
    the cost thereof in an amount approved by the Attorney
    General.”). And for convictions in states with no death penalty,
    both statutes require conformity to the “manner” of execution
    in some other state designated by the sentencing judge.
    Compare 
    18 U.S.C. § 3596
    (a) (“If the law of the State does not
    provide for implementation of a sentence of death, the court
    shall designate another State, the law of which does provide for
    the implementation of a sentence of death, and the sentence
    shall be implemented in the latter State in the manner
    prescribed by such law.”), with 50 Stat. at 304 (“If the laws of
    the State within which sentence is imposed make no provision
    for the infliction of the penalty of death, then the court shall
    designate some other State in which such sentence shall be
    10
    executed in the manner prescribed by the laws thereof.”). This
    wholesale copying surely indicates the preservation—not
    abrogation—of previously settled understandings.
    Nothing in 1994 usage compels a different understanding.
    To the contrary, at that time, many state statutes continued to
    describe the “manner” of execution as a top-line choice among
    methods such as electrocution, lethal gas, or lethal injection.
    See, e.g., 
    Cal. Penal Code § 3604
    (a), (d) (1994) (“manner of
    execution” is either by “lethal gas” or “intravenous injection of
    a substance or substances in a lethal quantity sufficient to cause
    death”); La. Rev. Stat. Ann. § 15:569 (1994) (“manner of
    execution” is either “electrocution,” defined as “causing to pass
    through the body of the person convicted a current of electricity
    of sufficient intensity to cause death,” or “lethal injection,”
    defined as “the intravenous injection of a substance or
    substances in a lethal quantity into the body of a person
    convicted”); 
    Mo. Rev. Stat. § 546.720
     (1994) (“The manner of
    inflicting the punishment of death shall be by the
    administration of lethal gas or by means of the administration
    of lethal injection.”); 
    Vt. Stat. Ann. tit. 13, § 7106
     (1994)
    (“Manner of execution” is “causing to pass through the body of
    the convict a current of electricity of sufficient intensity to
    cause death”). A handful of state statutes went one small step
    further, by using “manner” to refer to types of lethal
    substances. But none of them required the use of any particular
    substance, much less even more granular details. See 
    Colo. Rev. Stat. § 16-11-401
     (1994) (“The manner of inflicting the
    punishment of death shall be by the administration of a lethal
    injection,” defined as “continuous intravenous injection of a
    lethal quantity of sodium thiopental or other equally or more
    effective substance sufficient to cause death.”); Md. Code
    Ann., Crimes and Punishments § 71(a) (1994) (“The manner of
    inflicting the punishment of death shall be the continuous
    intravenous administration of a lethal quantity of an ultrashort-
    11
    acting barbiturate or other similar drug in combination with a
    chemical paralytic agent.”);4 
    Miss. Code Ann. § 99-19-51
    (1994) (similar to Maryland, but with alternative provision that
    “the manner of inflicting the punishment of death shall be by
    lethal gas”); 
    Okla. Stat. tit. 22, § 1014
     (1994) (“Manner of
    inflicting punishment of death” is either “continuous,
    intravenous administration of a lethal quantity of an ultrashort-
    acting barbiturate in combination with a chemical paralytic
    agent,” or “electrocution” or “firing squad”).5
    As of 1994, Supreme Court decisions reflected similar
    understandings. Between 1937 and 1994, the Court became
    much more active in policing capital punishment. But the
    Court never retreated from its holdings that the firing squad and
    electrocution are constitutional methods of execution.
    Likewise, the Court had not yet approved granular, post-habeas
    challenges to the specific details of an execution. To the
    contrary, in Gomez v. United States District Court, 
    503 U.S. 653
     (1992) (per curiam), the Court summarily rejected a claim
    that “execution by lethal gas” violated the Eighth Amendment,
    and it did so because the claim had not been properly channeled
    through the federal habeas statute. 
    Id.
     at 653–54. The Court’s
    first, tentative approval of claims challenging procedural
    details such as the method of “venous access” did not come
    until a decade after the FDPA was enacted, Nelson v.
    4
    Three other states used a similar formulation. See 
    N.H. Rev. Stat. Ann. § 630:5
    , XIII (1994); N.M. Stat. § 31-14-11 (1994); S.D.
    Codified Laws § 23A-27A-32 (1994).
    5
    Despite this occasional, slightly broader usage of “manner” in state
    statutes, the traditional usage remained common, and no state statute
    even remotely addressed items such as the details of catheter
    insertion. In any event, the obvious model for the FDPA was the
    1937 federal statute, so it is by far the most important data point.
    12
    Campbell, 
    541 U.S. 637
     (2004), and its wholesale approval of
    post-habeas challenges to the details of lethal-injection
    protocols did not come until even later, Hill v. McDonough,
    
    547 U.S. 573
     (2006).6
    In sum, practices and usages in 1994 mirrored those in
    1937: Inquiries into the manner or method of execution
    focused on the choice between say, lethal gas or lethal
    injection—not the choice of specific lethal agents or
    procedures for releasing the gas or inserting the catheter. In
    common understanding, what mattered was the top-line choice.
    Within the FDPA itself, statutory context reinforces this
    understanding. The FDPA states that the marshal responsible
    for supervising a federal execution “may use appropriate State
    or local facilities” and “may use the services of an appropriate
    State or local official.” 
    18 U.S.C. § 3597
    (a). These grants of
    authority would be unnecessary if section 3596(a), the
    “manner” provision directly at issue, independently required
    the use of all state execution procedures. After all, states
    conduct executions in designated state facilities. See, e.g., 
    Ind. Code § 35-38-6-5
     (2019) (“inside the walls of the state
    prison”); 
    Mo. Rev. Stat. § 546.720
     (2019) (“within the walls of
    a correctional facility of the department of corrections”); Tex.
    Dep’t of Crim. Justice, Execution Procedure § III.B (2019)
    (Huntsville Unit). Thus, if section 3596 required use of state
    facilities, section 3597 accomplished nothing by permitting
    their use. Of course, interpretations that create surplusage are
    disfavored. See, e.g., TRW Inc. v. Andrews, 
    534 U.S. 19
    , 31
    6
    Judge Rao cites a handful of judicial opinions loosely using the
    word “manner” to refer to subsidiary execution details. Post, at 4–5
    & n.2. Three of them post-date Nelson and Hill—the first Supreme
    Court decisions to suggest that such details might have any legal
    relevance. Two others are either lower-court decisions or dissents.
    None involves a statutory usage of “manner.”
    13
    (2001). The plaintiffs respond that section 3597 creates a
    “limited exception to Section 3596, permitting (but not
    requiring) the Government to use its own facilities.”
    Appellees’ Br. 30 n.6. But that makes section 3597 even
    stranger, for providing that the federal government “may” use
    “State” facilities would be a remarkably clumsy way of
    permitting the federal government to use federal facilities.
    Finally, consider statutory design. In “ascertaining the
    plain meaning of the statute, the court must look to the
    particular statutory language at issue, as well as the language
    and design of the statute as a whole.” K Mart Corp. v. Cartier,
    Inc., 
    486 U.S. 281
    , 291 (1988). Here, the plaintiffs’
    interpretation of “manner” would frustrate a principal objective
    of the Federal Death Penalty Act—to provide for an
    administrable scheme of capital punishment. As Justice Alito
    explained, the plaintiffs’ interpretation “would require the BOP
    to follow procedures that have been attacked as less safe than
    the ones the BOP has devised (after extensive study); it would
    demand that the BOP pointlessly copy minor details of a State’s
    protocol; and it could well make it impossible to carry out
    executions of prisoners sentenced in some States.” Barr v.
    Roane, 
    140 S. Ct. 353
    , 353 (2019) (statement of Alito, J.). The
    plaintiffs dismiss these points as mere policy arguments, but
    they are more than that.
    The FDPA was enacted as Title VI of the Violent Crime
    Control and Law Enforcement Act of 1994. See Pub. L. No.
    103-322, § 60001, 
    108 Stat. 1796
    , 1959. These statutes sought
    to ensure a workable and expanded system of capital
    punishment. The larger statute created more than two dozen
    new capital offenses. See DOJ, Criminal Resource Manual
    § 69 (2020). And the FDPA established procedures to ensure
    the fair administration of capital punishment—by specifying
    aggravating circumstances that a jury must find in order to
    14
    render the defendant eligible for the death penalty, 
    18 U.S.C. § 3592
    (b)–(d); by allowing a jury to consider any mitigating
    circumstances, 
    id.
     § 3592(a); and by requiring separate guilt
    and sentencing determinations, id. § 3593. These provisions
    cured potential Eighth Amendment problems, see, e.g.,
    Maynard v. Cartwright, 
    486 U.S. 356
    , 361–63 (1988)
    (aggravating factors); Eddings v. Oklahoma, 
    455 U.S. 104
    ,
    110–12 (1982) (mitigating factors); Gregg v. Georgia, 
    428 U.S. 153
    , 190–92 (1976) (plurality opinion) (separate
    sentencing hearing), to ensure that the scheme would be usable.
    Finally, the FDPA contains one provision specifically designed
    to prevent the choices of an individual state from effectively
    nullifying the federal death penalty. It provides: “If the law of
    the State does not provide for implementation of a sentence of
    death, the court shall designate another State, the law of which
    does provide for the implementation of a sentence of death ….”
    
    18 U.S.C. § 3596
    (a).
    The plaintiffs do not dispute that this scheme would be
    upset if individual states could effectively obstruct the federal
    death penalty. Yet their interpretation would make such
    obstruction likely. For example, states could block federal
    death sentences by refusing to disclose their full execution
    protocols. Some might do so because of moratoria on the use
    of capital punishment, like those ordered by the governors of
    California and Pennsylvania.7 Other states simply may wish
    not to assist in the enforcement of federal law. See, e.g., Printz
    v. United States, 
    521 U.S. 898
    , 923 (1997). And state statutes
    may prohibit disclosure of state execution protocols. See, e.g.,
    
    Ark. Code Ann. § 5-4-617
    (i)(1) (2019). The plaintiffs’ only
    7
    See Calif. Exec. Order No. N-09-19 (Mar. 13, 2019); Governor
    Tom Wolf Announces a Moratorium on the Death Penalty in
    Pennsylvania, Office of the Pa. Gov. (Feb. 13, 2015), https://www.
    governor.pa.gov/newsroom/moratorium-on-the-death-penalty-in-
    pennsylvania.
    15
    response is that the federal government obtained several state
    protocols in developing its own 2019 protocol. Yet while about
    thirty states authorize capital punishment, the federal
    government was able to obtain only five actual state protocols,
    plus a “summary” of the others provided by a private advocacy
    group. App. 10.
    Adherence to the minutiae of state execution protocols is
    not only pointless, but practically impossible. State protocols
    are as detailed as the federal one—from Arkansas’s color-
    coding to ensure that three lethal agents are properly separated
    among nine syringes, Arkansas Lethal Injection Procedure,
    Attachment C, § III.5.a (Aug. 6, 2015), to Indiana’s seventeen-
    step “procedure for venous cut down,” Ind. Dep’t of Corr.,
    Facility Directive ISP 06-26: Execution of Death Sentence,
    Appendix A (Jan. 22, 2014). Conducting a single execution
    under the federal protocol requires extensive preparation by a
    trained execution team of over 40 individuals, as well as further
    support from 250 more individuals at the federal execution
    facility in Terre Haute, Indiana. App. 93–94. Simultaneously
    managing the same logistical challenges under a few dozen
    state protocols—all different—would be all but impossible.
    The plaintiffs offer two limiting principles to mitigate this
    problem, but neither would work. First, they suggest a de
    minimis exception to the otherwise unyielding requirement to
    follow state procedures. But that would invite endless
    litigation over which requirements are de minimis. Must the
    federal government follow state provisions regarding the
    number of backup syringes? Compare App. 75 (two sets under
    federal protocol), with Mo. Dep’t of Corr., Preparation and
    Administration of Chemicals for Lethal Injection §§ B, E (one
    set under Missouri protocol). The type of catheters used? The
    selection of execution personnel? The training of those
    personnel? The same problem inheres in the plaintiffs’ related
    16
    suggestion that some protocol details might not relate
    sufficiently to “implementation” of the sentence. Would that
    exception cover rules for how long the inmate must remain
    strapped to the gurney? App. 40 (under federal protocol,
    between 30 minutes and three hours). Rules about whom the
    inmate may have present? Rules about the inmate’s final meal
    or final statement? Rules about opening and closing the
    execution chamber’s drapes? All such questions would be
    raised at the last minute—likely producing stays, temporary
    restraining orders, preliminary injunctions, and interlocutory
    appeals like this one, which will delay lawful executions for
    months if not years. In sum, the plaintiffs’ interpretation would
    make the federal death penalty virtually un-administrable.8
    2
    The plaintiffs’ further counterarguments are unavailing.
    First, the plaintiffs highlight the statutory text immediately
    surrounding “manner”—the language stating that a United
    States marshal “shall supervise implementation” of a death
    sentence in the manner prescribed by state law. 
    18 U.S.C. § 3596
    (a). The plaintiffs contend that “implementation” of a
    death sentence refers to the entire process for carrying it out,
    not just the use of a top-line execution method. But the only
    8
    Judge Rao correctly notes that bargains reflected in statutory text
    must be enforced as against generalized appeals to statutory purpose.
    Post, at 22–24. But statutory purpose, as reflected in “the language
    and design of the statute as a whole,” can help determine textual
    meaning or resolve textual ambiguity. See, e.g., K Mart, 
    486 U.S. at 291
    . Judge Rao does not dispute that one significant purpose of the
    FDPA is to ensure an administrable system of capital punishment,
    and her own analysis thus properly considers whether the plaintiffs’
    proposed construction would raise “practical, and perhaps
    insurmountable, difficulties to the implementation of federal death
    sentences.” Post, at 12–13.
    17
    implementing detail that must follow state law is the “manner”
    of carrying out the execution—which begs the question of what
    that term does and does not encompass.
    The plaintiffs next invoke a different FDPA provision
    defining aggravating circumstances to include cases where
    “[t]he defendant committed the offense in an especially
    heinous, cruel, or depraved manner in that it involved torture
    or serious physical abuse to the victim.”           
    18 U.S.C. § 3592
    (c)(6). They reason that this FDPA provision uses
    “manner” broadly, so other FDPA provisions must do likewise.
    But the presumption of consistent usage “readily yields to
    context, especially when” the term at issue “takes on distinct
    characters in distinct statutory provisions.” Return Mail, Inc.
    v. USPS, 
    139 S. Ct. 1853
    , 1863 (2019) (quotation marks
    omitted). That qualification perfectly fits this case, for each
    FDPA provision has its own history. As explained above, the
    provision regarding the “manner” of executing a death sentence
    traces back to the Crimes Act of 1790. In contrast, section
    3592(c)(6) was copied nearly verbatim from the Anti-Drug
    Abuse Act of 1988, see Pub. L. No. 100-690, § 7001, 
    102 Stat. 4181
    , 4392, which in turn responded to a Supreme Court
    decision allowing consideration of a “heinous, atrocious, or
    cruel” aggravating factor only as narrowed to require “torture
    or serious physical abuse,” Cartwright, 
    486 U.S. at
    363–65
    (quotation marks omitted). Because section 3592(c)(6) carries
    its own “old soil,” the presumption of consistent usage must
    yield to context.
    Finally, the plaintiffs stress that between 1995 and 2008,
    Congress failed to enact some nine bills that would have
    allowed federal capital punishment to be implemented in a
    manner independent of state law. But “failed legislative
    proposals are a particularly dangerous ground on which to rest
    an interpretation of a prior statute.” Cent. Bank of Denver, N.A.
    18
    v. First Interstate Bank of Denver, N.A., 
    511 U.S. 164
    , 187
    (1994) (quotation marks omitted). The plaintiffs highlight DOJ
    statements that the FDPA imperiled its 1993 regulation, which
    establishes lethal injection as the sole method for federal
    executions. But those statements were made when some states
    still provided for electrocution “as the sole method of
    execution.” See Baze, 
    553 U.S. at
    42–43 n.1 (plurality
    opinion). In 2009, Nebraska became the last death-penalty
    state to authorize lethal injection as a permissible execution
    method. See Act of May 28, 2009, L.B. 36, 
    2009 Neb. Laws 52
    . After that, attempts to amend the FDPA ceased, as did
    DOJ’s support for them. So, DOJ’s current interpretation of
    the FDPA to encompass methods of execution, but not
    subsidiary procedural details, has been consistent.
    3
    Judge Rao takes a different approach advocated by none of
    the parties. In her view, the word “manner” is flexible enough,
    considered in isolation, to refer either to the top-line method of
    execution or to the full panoply of execution procedures. Post,
    at 1–6. So far, so good. She then reasons that, by requiring
    federal executions to be conducted “in the manner prescribed
    by the law of the State in which the sentence is imposed,”
    Congress specified “the level of generality” for interpreting the
    word “manner.” 
    Id. at 1
    . She thus concludes that Congress
    used “manner” in its broad sense, so as to include all execution
    procedures—no matter how picayune—that are “prescribed by
    the law of the State.” 
    Id. at 22
    . For Judge Rao, as it turns out,
    the key to this case is not the word “manner,” but the phrase
    “prescribed by the law of the State.”
    This account runs contrary to established rules of grammar
    and statutory interpretation. As a matter of grammar, the
    participial phrase “prescribed by the law of the State” functions
    19
    as an adjective and modifies the noun “manner.” By using the
    adjective to construe the noun broadly, Judge Rao overlooks
    “the ordinary understanding of how adjectives work.”
    Weyerhaeuser Co. v. U.S. Fish & Wildlife Serv., 
    139 S. Ct. 361
    ,
    368 (2018). “Adjectives modify nouns—they pick out a subset
    of a category that possesses a certain quality.” 
    Id.
     They
    ordinarily do not expand the meaning of the noun they modify.
    Thus, “critical habitat” must first be “habitat.” See 
    id.
    Likewise, “full costs” must first be “costs.” See Rimini Street,
    Inc. v. Oracle USA, Inc., 
    139 S. Ct. 873
    , 878–79 (2019). And
    here, whatever is “prescribed by the law of the State” must first
    be a “manner” of execution. In short, the limiting adjective
    provides no basis for interpreting the noun broadly.
    To be sure, adjectival phrases can clarify the meaning of
    ambiguous nouns by ruling out certain possibilities through
    context. For example, in the abstract, the noun “check” might
    refer to “an inspection, an impeding of someone else’s
    progress, a restaurant bill, a commercial instrument, a patterned
    square on a fabric, or a distinctive mark-off.” A. Scalia &
    B. Garner, Reading Law: The Interpretation of Legal Texts 70
    (2012). But when “check” is combined with the adjectival
    phrase “made payable to the IRS,” we know that the noun
    refers only to a commercial instrument. In this example, the
    phrase “made payable to the IRS” clarifies the meaning of
    “check” because it is consistent with only one possible
    understanding of it.
    The FDPA does not work like that. Divorced from its
    statutory history, the noun “manner” could mean either the top-
    line execution method or all state execution procedures. But
    the adjectival phrase “prescribed by the law of the State”
    cannot resolve this ambiguity, because it is perfectly consistent
    with both meanings. On the one hand, states use their laws to
    prescribe the top-line method of execution. On the other hand,
    20
    they also use their laws to specify additional procedural details.
    So the adjectival phrase “prescribed by the law of the State”
    tells us nothing about the meaning of the noun “manner”—and
    certainly does not undermine a historical understanding of that
    term dating back to our country’s founding.9
    Judge Rao stresses the assertedly limited scope of her
    reading of the FDPA. She interprets the phrase “prescribed by
    the law of the State” to mean execution procedures set forth
    only in state “statutes and regulations carrying the force of
    law,” but not in less formal state execution protocols. Post, at
    6. And that interpretation, she concludes, “mitigates many of
    the concerns raised by the district court’s broad reading” of the
    FDPA. Id. at 26. All of this is a good reason for rejecting an
    interpretation of the FDPA that encompasses procedural details
    set forth only in state execution protocols. But it is not a good
    reason for rejecting the historical understanding of “manner,”
    which creates no practical concerns about administrability.
    Judge Rao also understates the practical difficulties with
    her proposed interpretation. For one thing, state statutes and
    regulations do contain many granular details. Consider just the
    four state death-penalty statutes before us in this case. The
    Arkansas statute requires that catheters be “sterilized and
    prepared in a manner that is safe.” 
    Ark. Code Ann. § 5-4
    -
    617(f) (2019). The Indiana statute excludes lawyers from the
    persons who “may be present at the execution.” Ind. Code
    9
    To make the adjectival reference to state law narrow the noun
    “manner,” Judge Rao must retreat to the position that “manner,”
    construed without reference to the adjectival phrase, “is broad
    enough to encompass execution procedures at every level of
    generality.” Post, at 9 n.5. As explained above, that position cannot
    be reconciled with historical usages and understandings tracing back
    to the First Congress.
    21
    § 35-38-6-6(a) (2019). The Missouri statute requires the
    execution chamber to be “suitable and efficient.” 
    Mo. Rev. Stat. § 546.720.1
     (2019). And the Texas statute prohibits the
    infliction of any “unnecessary pain” on the condemned
    prisoner. Tex. Code Crim. Proc. Ann. art. 43.24 (2019).
    Assimilating the various state statutes and regulations will
    present significant logistical challenges. And, of course, these
    various provisions will provide ample opportunity for last-
    minute stay litigation.
    Moreover, the line between “formal” regulations “carrying
    the force of law” and “informal policy or protocol,” post, at 6–
    8, will be another fertile source of litigation. At the state level,
    how “formal” is formal enough? Even at the federal level, the
    question of which regulations have the force of law has been
    “the source of much scholarly and judicial debate.” Perez v.
    Mortg. Bankers Ass’n, 
    575 U.S. 92
    , 96 (2015). Yet now, courts
    will be forced to confront every variation of that question
    arising out of the administrative law of some thirty states.
    What if a state administrative procedure act permits rulemaking
    through processes less formal than notice-and-comment?
    What if a warden may change protocol procedures unilaterally,
    but only under limited circumstances? What if a state court
    moves the goalposts with an unexpected interpretation of the
    governing rules? Litigation over such matters will foreclose
    any realistic possibility for the prompt execution of federal
    death sentences.10
    10
    To be clear, I agree with Judge Rao that the FDPA’s reference to
    “law of the State” covers only state statutes and binding regulations.
    Post, at 6–8. I also agree with Judge Rao that because the state
    protocols in this case “do not appear to have the binding force of law,
    they cannot be deemed part of the ‘law of the State.’” 
    Id.
     at 28 n.15.
    Accordingly, those propositions constitute holdings of this Court.
    22
    * * * *
    For all these reasons, I would hold that the FDPA requires
    the federal government to follow state law regarding only the
    method of execution and does not regulate the various
    subsidiary details cited by the plaintiffs and the district court.
    On that interpretation, the plaintiffs’ primary FDPA claim is
    without merit.
    B
    In the alternative, the plaintiffs contend that the 2019
    protocol violates the FDPA by impermissibly shifting authority
    from the United States Marshals Service to the Federal Bureau
    of Prisons. The plaintiffs rest this argument on FDPA
    provisions requiring a United States marshal to “supervise
    implementation” of the death sentence. 
    18 U.S.C. § 3596
    (a);
    see also 
    id.
     § 3597(a). The district court did not reach this
    argument, but the parties have briefed it and the plaintiffs urge
    it as an alternative ground for affirmance.
    The execution protocol does not strip the Marshals Service
    of the power to supervise executions. To the contrary, it
    requires a “United States Marshal designated by the Director
    of the USMS” to oversee the execution and to direct which
    other personnel may be present at it. App. 30. The “execution
    process,” which starts at least thirty minutes before the actual
    execution, cannot begin without the marshal’s approval. App.
    40. The same is true for the execution itself. App. 44, 68.
    Individuals administering the lethal agents are “acting at the
    See Marks v. United States, 
    430 U.S. 188
    , 193–94 (1977). But I do
    not share Judge Rao’s optimism that a “law of the State” limitation,
    imposed on an otherwise unbounded interpretation of “manner,” will
    avoid “practical, and perhaps insurmountable, difficulties to the
    implementation of federal death sentences.” Post, at 12–13.
    23
    direction of the United States Marshal.” App. 74. And once
    the execution is complete, the marshal must notify the court
    that its sentence has been carried out. App. 44–45. The
    protocol thus tasks the USMS with supervising executions.
    In any event, federal law vests all powers of DOJ
    components in the Attorney General and permits him to
    reassign powers among the components. “All functions of
    other officers of the Department of Justice and all functions of
    agencies and employees of the Department of Justice are vested
    in the Attorney General.” 
    28 U.S.C. § 509
    . The Marshals
    Service is “a bureau within the Department of Justice under the
    authority and direction of the Attorney General.” 
    Id.
     § 561(a).
    Its powers are thus ultimately vested in the Attorney General.
    Moreover, the Attorney General may delegate his powers to
    “any other officer, employee, or agency of the Department of
    Justice.” Id. § 510. Together, these provisions permit the
    Attorney General to reassign duties from the Marshals Service
    to the Bureau of Prisons.
    The plaintiffs invoke United States v. Giordano, 
    416 U.S. 505
     (1974). There, the Supreme Court held that a statute
    “expressly” limiting the Attorney General’s power to delegate
    wiretap authority to a handful of enumerated officials qualified
    his general authority to reassign DOJ functions. 
    Id. at 514
    . But
    the FDPA contains no such language expressly prohibiting the
    Attorney General from deciding or delegating matters relating
    to executions. For these reasons, the protocol allocates duties
    consistent with the FDPA, so the plaintiffs’ alternative FDPA
    argument is also without merit.11
    11
    Judge Rao contends that the plaintiffs forfeited this argument by
    not raising it below. Post, at 32. But plaintiff Lee, in support of his
    motion for a preliminary injunction, identified eight provisions in the
    24
    C
    The federal protocol is both a procedural rule and a general
    policy statement exempted from the notice-and-comment
    requirements of the Administrative Procedure Act. See 
    5 U.S.C. § 553
    (b)(3)(A).
    “The critical feature of a procedural rule is that it covers
    agency actions that do not themselves alter the rights or
    interests of parties.” Nat’l Mining Ass’n v. McCarthy, 
    758 F.3d 243
    , 250 (D.C. Cir. 2014) (quotation marks omitted). The
    federal protocol does not alter the plaintiffs’ rights or interests,
    which were all but extinguished when juries convicted and
    sentenced them to death.          Moreover, pre-existing law
    establishes lethal injection as the method of execution, 
    28 C.F.R. § 26.3
    (a)(4), and the protocol simply sets forth
    procedures for carrying out the injections.
    The execution protocol is also a general statement of
    agency policy. In defining this category, “[o]ne line of analysis
    execution protocol that he says impermissibly granted authority to
    the Bureau of Prisons. See Lee Mot. for Prelim. Inj., In re Execution
    Protocol Cases, No. 1:19-mc-145 (D.D.C.), ECF Doc. 13-1, at 10–
    12. Lee argued that each of the provisions is “[c]ontrary to Section
    3596 of [the] FDPA, which only refers to the U.S. Marshal
    supervising implementation.” 
    Id.
     Moreover, the government did not
    argue for a forfeiture, and thus “forfeited [the] forfeiture argument
    here.” Solomon v. Vilsack, 
    763 F.3d 1
    , 13 (D.C. Cir. 2014). And for
    several reasons, it would make good sense for us to excuse any
    forfeiture: The plaintiffs’ alternative FDPA claim turns on purely
    legal questions, it was fully briefed on appeal, both parties ask us to
    decide it, the Supreme Court has asked us to proceed with
    appropriate dispatch, and this claim, even if not pursued in the
    preliminary-injunction motions, would remain live on remand.
    25
    considers the effects of an agency’s action, inquiring whether
    the agency has (1) impose[d] any rights and obligations, or (2)
    genuinely [left] the agency and its decisionmakers free to
    exercise discretion.” Clarian Health West, LLC v. Hargan, 
    878 F.3d 346
    , 357 (D.C. Cir. 2017) (quotation marks omitted). A
    second line “looks to the agency’s expressed intentions,
    including consideration of three factors: (1) the [a]gency’s own
    characterization of the action; (2) whether the action was
    published in the Federal Register or the Code of Federal
    Regulations; and (3) whether the action has binding effects on
    private parties or on the agency.” 
    Id.
     (quotation marks
    omitted). Here, the protocol contains no rights-creating
    language. Just the opposite, it states that “[t]his manual
    explains internal government procedures and does not create
    any legally enforceable rights or obligations.” App. 24.
    Likewise, the protocol explicitly permits “deviation[s]” and
    “adjustment[s]” upon a determination “by the Director of the
    BOP or the Warden” that the deviation is “required,” thus
    preserving a healthy measure of agency discretion. 
    Id.
     Finally,
    the protocol was published in neither the Code of Federal
    Regulations nor the Federal Register.
    For these reasons, the federal protocol was not subject to
    notice-and-comment requirements, and the plaintiffs’ contrary
    claim is without merit.12
    12
    Given the flexibility built into the federal protocol, I agree with
    Judge Rao that it may be adjusted to conform to state law to whatever
    extent the FDPA may require. Post, at 29–30. That saves the
    protocol itself from attack under Judge Rao’s construction of the
    FDPA. But, as explained above, it opens the door to a wide range of
    challenges to federal executions under the minutiae of state
    execution statutes and regulations.
    26
    II
    Wholly apart from the merits, I would reverse the
    preliminary injunction because the balance of harms and the
    public interest strongly favor the government. The party
    seeking a preliminary injunction “must establish” not only a
    likelihood of success on the merits, but also “that the balance
    of equities tips in his favor, and that an injunction is in the
    public interest.” Winter v. NRDC, 
    555 U.S. 7
    , 20 (2008); see
    also Amoco Prod. Co. v. Vill. of Gambell, 
    480 U.S. 531
    , 542
    (1987). And appellate courts may reverse preliminary
    injunctions where, apart from the merits, the district court’s
    equitable balancing constituted an abuse of discretion. See
    NRDC, 
    555 U.S. at
    24–26, 32.
    In this case, the district court failed to recognize the
    important governmental and public interest in the timely
    implementation of capital punishment. The court concluded
    that any “potential harm to the government caused by a delayed
    execution is not substantial.” In re Execution Protocol Cases,
    
    2019 WL 6691814
    , at *7. In contrast, the Supreme Court
    frequently has explained that “both the [government] and the
    victims of crime have an important interest in the timely
    enforcement of a [death] sentence,” which is frustrated by
    decades of litigation-driven delay. Bucklew, 
    139 S. Ct. at 1133
    (quotation marks omitted). Indeed, “when lengthy federal
    proceedings have run their course”—as is the case here—
    “finality acquires an added moral dimension.” Calderon v.
    Thompson, 
    523 U.S. 538
    , 556 (1998). “Only with an assurance
    of real finality can the State execute its moral judgment in a
    case.” 
    Id.
     And “[o]nly with real finality can the victims of
    crime move forward knowing the moral judgment will be
    carried out.” 
    Id.
     “To unsettle these expectations is to inflict a
    profound injury to the ‘powerful and legitimate interest in
    27
    punishing the guilty.’” 
    Id.
     (quoting Herrera v. Collins, 
    506 U.S. 390
    , 421 (1993) (O’Connor, J., concurring)).
    These interests are magnified by the heinous nature of the
    offenses committed by the appellees—all of whom murdered
    children—as well as the decades of delay to date.
    In 1999, an Arkansas jury convicted Daniel Lee of three
    counts of murder in aid of racketeering. The murders were
    committed in 1996, during a robbery to fund a white
    supremacist organization. United States v. Lee, 
    374 F.3d 637
    ,
    641 (8th Cir. 2004). After overpowering a couple and their
    eight-year-old daughter in their home, Lee and a confederate
    “shot the three victims with a stun gun, placed plastic bags over
    their heads, and sealed the bags with duct tape.” 
    Id.
     at 641–42.
    They then drove the family to a bayou, taped rocks to their
    bodies, and threw them into the water to suffocate or drown.
    
    Id. at 642
    . The Eighth Circuit affirmed Lee’s death sentence
    on direct review, 
    id.,
     and thrice denied him collateral relief, Lee
    v. United States, No. 19-3576 (8th Cir. Jan. 7, 2020); United
    States v. Lee, 
    792 F.3d 1021
     (8th Cir. 2015); United States v.
    Lee, 
    715 F.3d 215
     (8th Cir. 2013). Nonetheless, Lee continues
    to pursue a fourth round of collateral review. Lee v. United
    States, No. 2:19-cv-00468 (S.D. Ind. Dec. 5, 2019),
    preliminary injunction vacated by Lee v. Watson, No. 19-3399
    (7th Cir. Dec. 6, 2019).
    In 2003, a Missouri jury convicted Wesley Purkey of the
    kidnapping, rape, and murder of sixteen-year-old Jennifer
    Long in 1998. United States v. Purkey, 
    428 F.3d 738
    , 744–45
    (8th Cir. 2005). After killing the girl, Purkey dismembered her
    body with a chainsaw and burned her remains. 
    Id. at 745
    . The
    jury found nine aggravating factors, including that Purkey had
    previously bludgeoned a woman to death with a hammer. 
    Id. at 746
    . The Eighth Circuit affirmed Purkey’s death sentence
    28
    on direct review, 
    id. at 744
    , and later denied him collateral
    relief, Purkey v. United States, 
    729 F.3d 860
     (8th Cir. 2013).
    In 2004, an Iowa jury convicted Dustin Honken of
    murdering five individuals in 1999, including two witnesses to
    his drug trafficking and two young children. United States v.
    Honken, 
    541 F.3d 1146
    , 1148 (8th Cir. 2008). Honken and an
    accomplice kidnapped one witness, the witness’s girlfriend,
    and her six- and ten-year-old daughters. Honken murdered all
    four execution-style, by shooting each in the head. 
    Id.
     at 1149–
    51. Four months later, Honken murdered another prospective
    witness against him. 
    Id. at 1148, 1151
    . Then, while in prison
    awaiting trial, he made plans to murder additional witnesses.
    
    Id.
     at 1150–51. Because Iowa has no death penalty, the district
    court ordered Honken to be executed in the manner provided
    by Indiana law. The Eighth Circuit affirmed the death sentence
    on direct appeal, 
    id. at 1148
    , and then declined to set it aside on
    collateral review, see Honken v. United States, 
    42 F. Supp. 3d 937
    , 1196–97 (N.D. Iowa 2013), certificate of appealability
    denied, No. 14-1329 (8th Cir. May 2, 2014).
    In 2004, a Texas jury convicted Alfred Bourgeois of
    murdering his two-year-old daughter in 2002. United States v.
    Bourgeois, 
    423 F.3d 501
    , 503 (5th Cir. 2005). Before the
    murder, Bourgeois “systematically abused and tortured” the
    child—he punched her in the face, whipped her with an
    electrical cord, hit her head with a plastic bat so many times
    that it “was swollen like a football,” and later bragged to a
    fellow inmate that the “f––ing baby’s head got as big as a
    watermelon.” 
    Id.
     He bit her, scratched her, and burned the
    bottom of her feet with a cigarette lighter. When others tried
    to clean the sores, Bourgeois “would stop them and jam his
    dirty thumb into the wounds, then force [her] to walk” on them.
    
    Id.
     After her training potty tipped over, Bourgeois repeatedly
    slammed the back of her head into a window. He refused to
    29
    take the girl’s limp body to the hospital, but a passer-by called
    an ambulance. “The doctors sustained [her] on life support
    until her mother could get to the hospital, where the baby died
    in her mother’s arms the next day.” 
    Id. at 505
    . In affirming
    the death sentence, the Fifth Circuit described this as “not a
    close case.” 
    Id. at 512
    . That court later denied post-conviction
    relief. United States v. Bourgeois, 537 F. App’x 604, 605 (5th
    Cir. 2013) (per curiam).
    These crimes were committed twenty-four, twenty-two,
    twenty-one, and eighteen years ago respectively. Each
    appellee received the full panoply of procedural protections
    afforded under the Constitution and the FDPA. Each received
    direct review and one or more rounds of collateral review. Yet
    now, supported by fifteen lawyers on just this appeal, they
    continue to litigate with a vengeance, ostensibly over the
    manner of their executions, but with the obvious and intended
    effect of delaying them indefinitely. As the Supreme Court
    noted in Bucklew, with apparent exasperation, the people and
    the surviving victims “deserve better.” 139 S. Ct. at 1134.
    The district court stressed that the government took eight
    years to craft its revised execution protocol. True enough, but
    things were fine in 2008, with a three-drug execution protocol
    in place and approved by the Supreme Court in Baze. Then
    began a long and successful campaign of obstruction by
    opponents of capital punishment, which removed sodium
    thiopental from the market by 2011 and made pentobarbital
    unavailable shortly thereafter. See Glossip v. Gross, 
    135 S. Ct. 2726
    , 2733 (2015). At that point, the government’s options
    were severely limited, and it can hardly be faulted for
    proceeding with caution. The government declined to press
    ahead with an available three-drug protocol using
    midazolam—a milder sedative than either sodium thiopental or
    pentobarbital—and two other substances to stop respiration
    30
    and induce cardiac arrest. Its hesitation in the face of
    uncertainty proved reasonable, as four Justices would later
    describe this protocol as possibly “the chemical equivalent of
    being burned at the stake.” 
    Id. at 2781
     (Sotomayor, J.,
    dissenting).
    Instead of proceeding with an inferior option, the
    government waited until pentobarbital again became available.
    That barbiturate—which can act as both sedative and lethal
    agent—is “widely conceded to be able to render a person fully
    insensate,” Zagorski v. Parker, 
    139 S. Ct. 11
    , 11–12 (2018)
    (Sotomayor, J., dissenting from denial of application for stay
    and denial of certiorari), thus ensuring a painless execution.
    The government also took time to study the successful track
    record of pentobarbital, documenting its use without incident
    in more than 100 state executions, A.R. 929–30, as well as the
    many cases that have upheld its use, see, e.g., Zink v. Lombardi,
    
    783 F.3d 1089
    , 1102 (8th Cir. 2015) (en banc) (per curiam);
    Ladd v. Livingston, 
    777 F.3d 286
    , 289–90 (5th Cir. 2015). The
    government’s care in selecting an available and effective
    execution substance does not diminish the importance of
    carrying out the appellees’ sentences.
    On the other side of the balance, a death sentence is of
    course serious business. But here, there is no dispute that the
    appellees may be executed by lethal injection, nor any
    colorable dispute that pentobarbital will cause anything but a
    swift and painless death. Instead, the plaintiffs contend only
    that their executions cannot occur until the federal government
    replicates every jot-and-tittle of the relevant state execution
    protocols. And in doing so, they would expose other death-row
    inmates to substances less reliably certain to ensure a painless
    death than is pentobarbital—including midazolam, which
    remains in use in five different states. A.R. 92–93. The claims
    before us are designed neither to prevent unnecessary suffering
    31
    nor to ensure that needles are properly inserted into veins—a
    task that nurses routinely perform without difficulty. Instead,
    they are designed to delay lawful executions indefinitely. We
    should not assist in that undertaking.
    * * * *
    For these reasons, I would vacate the preliminary
    injunction and remand the case to the district court with
    instructions to enter judgment for the government on the
    plaintiffs’ FDPA claims and their notice-and-comment claims.
    RAO, Circuit Judge, concurring: The Department of
    Justice specified a range of procedures to govern federal
    executions in its 2019 protocol and addendum. Plaintiffs allege
    that the Department’s protocol is inconsistent with the Federal
    Death Penalty Act (“FDPA”), which requires that federal
    executions be implemented “in the manner prescribed by the
    law of the State in which the sentence is imposed.” 
    18 U.S.C. § 3596
    (a). At every stage of this litigation, the debate has
    centered on whether “manner” should be read at a particular
    level of generality. The word “manner,” however, cannot be
    interpreted in isolation. It is a broad, flexible term whose
    specificity depends on context. The FDPA explicitly defines
    the level of generality of “manner”: It is the “manner prescribed
    by the law of the State.” Thus, the FDPA requires the federal
    government to apply state law—that is, statutes and formal
    regulations—at whatever level of generality state law might be
    framed. Where state law is silent, the federal government has
    discretion to choose whatever lawful execution procedures it
    prefers.
    Under this interpretation, the Department of Justice’s 2019
    protocol is consistent with the FDPA. The protocol lays out a
    non-binding procedural framework that the federal government
    may apply in most cases, and it allows the U.S. Marshal Service
    to depart from federal procedures when required—a carveout
    that naturally would encompass situations in which the 2019
    protocol conflicts with state law. I therefore agree to vacate the
    preliminary injunction.
    I.
    Assessing the validity of the 2019 protocol requires us first
    to interpret the reach of the FDPA. The Department of Justice
    maintains that “manner” as used in the FDPA means only the
    method of execution—i.e., hanging, electrocution, or lethal
    injection—leaving the government free to set forth a uniform
    procedure for executions. The plaintiffs, on the other hand,
    2
    assert that “manner” means any procedures used by a state
    when implementing the death penalty, thereby precluding any
    kind of uniform federal protocol. Neither reading comports
    with the FDPA when read as a whole. In the FDPA, Congress
    left certain choices regarding execution to the States.
    Considering the text and structure of the statute, I explain why
    the FDPA requires the federal government to apply only those
    execution procedures prescribed by a state’s statutes and
    formal regulations, but leaves the federal government free to
    specify other procedures or protocols not inconsistent with
    state law. Moreover, nothing in the statutory history offers a
    basis to override the plain meaning of the FDPA.
    A.
    The FDPA provides that the U.S. Marshal “shall supervise
    implementation of the sentence [of death] in the manner
    prescribed by the law of the State in which the sentence is
    imposed.” 
    18 U.S.C. § 3596
    (a). The parties as well as my
    colleagues focus on the meaning of the word “manner.” As I
    explain, the word “manner” may refer to varying levels of
    specificity, both in its ordinary meaning and in the context of
    execution procedures. Reading “manner” alongside other
    words in Section 3596(a), as well as the statute as a whole,
    demonstrates that the FDPA uses “manner” to include the
    positive law and binding regulations of a state—those
    procedures “prescribed by the law of the State.” State “law,”
    however, does not include informal procedures or protocols. In
    the absence of binding state law, the FDPA leaves other
    procedures to the discretion of the U.S. Marshal who must
    “supervise implementation of the sentence” of death.
    1.
    In ordinary usage, the word “manner” has a broad, flexible
    meaning. A “manner” is “a characteristic or customary mode
    3
    of acting” or “a mode of procedure.” Manner, Merriam-
    Webster’s Collegiate Dictionary (11th ed. 2014). Put
    differently, a “manner” is “[a] way of doing something or the
    way in which a thing is done or happens.” Manner, The
    American Heritage Dictionary of the English Language (5th
    ed. 2018). “Manner” may therefore refer to a general way of
    doing something or the more specific way in which an action
    is carried out. The word had a similarly broad meaning when
    the first two federal death penalty statutes were passed in 1790
    and 1937. See Manner, New International Dictionary of the
    English Language (2d ed. 1941) (“[A] way of acting; a mode
    of procedure; the mode or method in which something is done
    or in which anything happens.”); 2 S. Johnson, A Dictionary of
    the English Language (1755) (“Custom; habit; fashion.”).1
    The word “manner” has the same flexible meaning in the
    execution context, as demonstrated by federal and state statutes
    and judicial decisions that use the word with varying levels of
    generality. As DOJ notes, the word is sometimes used to refer
    to a general execution method, and courts occasionally use the
    terms “manner” and “method” interchangeably; yet “manner”
    1
    Judge Katsas makes much of the fact that eighteenth-century
    dictionaries, including Samuel Johnson’s, also defined “manner” as
    a “method,” Concurring Op. 4–5 (Katsas, J.), but he overlooks that
    those dictionaries defined “method” in broad terms. For instance,
    Johnson’s dictionary states: “Method, taken in the largest sense,
    implies the placing of several things, or performing several
    operations in such an order as is most convenient to attain some end.”
    2 S. Johnson, A Dictionary of the English Language (1755). This
    “largest sense” is the only definition Johnson provides for “method.”
    Judge Katsas notes that “[o]ther dictionaries” also “indicate that
    ‘manner’ is synonymous with ‘method’ as well as ‘mode.’”
    Concurring Op. 4 (Katsas, J.). These dictionaries, however, are not
    referring to the narrow sense of “method” employed in the execution
    context.
    4
    is also frequently used to refer to granular details, including in
    the FDPA itself. In a provision governing aggravating factors
    in homicide cases, the statute reads, “In determining whether a
    sentence of death is justified …, the jury … shall consider …
    [whether] [t]he defendant committed the offense in an
    especially heinous, cruel, or depraved manner in that it
    involved torture or serious physical abuse to the victim.” 
    18 U.S.C. § 3592
    (c)(6). In this instance, the “manner” of
    committing homicide refers not to the general method of
    killing, but to the precise way in which the offense was
    committed.
    State legislatures also use the word “manner” to refer to
    the specifics of an execution procedure, including in some
    statutes the choice of lethal substance or method of injection.
    See, e.g., Miss. Code. Ann. § 99-19-51 (“The manner of
    inflicting the punishment of death shall be by the sequential
    intravenous administration of a lethal quantity of the following
    combination of substances ….”); Md. Code Ann., Correctional
    Services, § 3–905 (repealed in 2013) (“The manner of inflicting
    the punishment of death shall be the continuous intravenous
    administration of a lethal quantity of an ultrashort-acting
    barbiturate or other similar drug in combination with a
    chemical paralytic agent.”); 
    Colo. Rev. Stat. Ann. § 18-1.3
    -
    1202 (“The manner of inflicting the punishment of death shall
    be by the administration of a lethal injection …. For the
    purposes of this part 12, ‘lethal injection’ means a continuous
    intravenous injection of a lethal quantity of sodium thiopental
    or other equally or more effective substance.”).
    Similarly, federal courts use the term “manner” variably to
    refer both to the method of execution and to the specifics of
    execution procedures. See Glossip v. Gross, 
    135 S. Ct. 2726
    ,
    2741 (2015) (“[T]here is no scientific literature addressing the
    use of midazolam as a manner to administer lethal injections in
    5
    humans.” (quoting a party’s expert report)); 
    id. at 2790
    (Sotomayor, J., dissenting) (“These assertions were amply
    supported by the evidence of the manner in which midazolam
    is and can be used.”); Baze v. Rees, 
    553 U.S. 35
    , 57 (2008)
    (plurality opinion) (“[T]he Commonwealth’s continued use of
    the three-drug protocol cannot be viewed as posing an
    ‘objectively intolerable risk’ when no other State has adopted
    the one-drug method and petitioners proffered no study
    showing that it is an equally effective manner of imposing a
    death sentence.”); Holden v. Minnesota, 
    137 U.S. 483
    , 491
    (1890) (“[The state statute] prescribes … the manner in which[]
    the punishment by hanging shall be inflicted.”); Williams v.
    Hobbs, 
    658 F.3d 842
    , 849 (8th Cir. 2011) (“The prisoners next
    contend that they have demonstrated a facially plausible claim
    that the Act [which provides for lethal injection in all cases] …
    increases mental anxiety before execution since the prisoners
    cannot know the manner in which they will be executed.”).2
    These examples demonstrate that the word “manner” is used
    2
    See also Louisiana ex rel. Francis v. Resweber, 
    329 U.S. 459
    , 474
    (1947) (Burton, J., dissenting) (“The Supreme Court of Louisiana has
    held that electrocution, in the manner prescribed in its statute, is more
    humane than hanging.”); In re Kemmler, 
    136 U.S. 436
    , 443–44
    (1890) (“‘[T]he application of electricity to the vital parts of the
    human body, under such conditions and in the manner contemplated
    by the statute, must result in instantaneous, and consequently in
    painless, death.’” (citation omitted)); Harris v. Dretke, No. 04-
    70020, 
    2004 WL 1427042
    , at *1 (5th Cir. June 23, 2004) (“David
    Harris appeals the dismissal of his suit … challenging the manner in
    which the State of Texas intends to carry-out his execution by lethal
    injection.”).
    6
    frequently in the execution context as a broad term that may
    encompass any level of detail.3
    2.
    To determine the level of specificity of “manner” as used
    in the FDPA, I start with the language of Section 3596. Recall
    the statute provides that the U.S. Marshal “shall supervise
    implementation of the sentence in the manner prescribed by the
    law of the State in which the sentence is imposed.” 
    18 U.S.C. § 3596
    (a). In this context, “manner” does not operate in
    isolation, but is modified by the requirement that the Marshal
    adopt the manner “prescribed by the law of the State.” The
    district court did not address this qualifying language, and both
    parties gloss over it. In defending the 2019 protocol, the
    government contends that the Marshal must apply only the
    state’s method of execution, without reference to other details
    that might be included in state law; the plaintiffs contend that
    the Marshal must apply all state procedures, again without
    reference to whether those procedures were prescribed by state
    law. The government’s distinction is not found anywhere in the
    FDPA, while the plaintiffs’ interpretation would read the
    phrase “prescribed by … law” out of the statute entirely.
    The ordinary meaning of “law of the State” refers to
    binding law prescribed through formal lawmaking procedures.
    In analogous contexts, the Supreme Court has read similar
    statutory language to incorporate only statutes and regulations
    carrying the force of law. For instance, the Court held in United
    3
    As the question before us concerns the meaning of the FDPA and
    whether “manner” can include procedural details prescribed by state
    law, it is of no consequence that the Supreme Court recognized
    constitutional challenges to the procedural details of execution only
    relatively recently. See Concurring Op. 11–12 & n.6 (Katsas, J.).
    7
    States v. Howard that a Florida regulation was part of the “law
    of the state” because violations of the regulation were
    “punishable as a misdemeanor.” 
    352 U.S. 212
    , 216–17, 219
    (1957). In Chrysler Corporation v. Brown, the Court held that
    the phrase “authorized by law” encompasses “properly
    promulgated, substantive agency regulations” that “have the
    ‘force and effect of law.’” 
    441 U.S. 281
    , 295–96 (1979); see
    also Baltimore & O.R. Co. v. Baugh, 
    149 U.S. 368
    , 398 (1893)
    (“‘[T]he equal protection of the laws,’ … means equal
    protection not merely by the statutory enactments of the state,
    but equal protection by all the rules and regulations which,
    having the force of law, govern the intercourse of its citizens
    with each other and their relations to the public.”); Samuels v.
    Dist. of Columbia, 
    770 F.2d 184
    , 199 (D.C. Cir. 1985)
    (“[T]hose federal regulations adopted pursuant to a clear
    congressional mandate that have the full force and effect of
    law … have long been recognized as part of the body of federal
    law.”). The Supreme Court has emphasized that something is
    “prescribed by law” when it includes binding requirements. Cf.
    United States v. Rodriquez, 
    553 U.S. 377
    , 390–91 (2008)
    (holding that the phrase “maximum term of imprisonment …
    prescribed by law” refers to the statutory maximum, not the
    maximum set by sentencing guidelines, which do not bind a
    judge in all circumstances). Consistent with the deep-rooted
    conception of law as fixed and binding, I have not found, nor
    did the plaintiffs cite, any case in which the Supreme Court or
    this court has held that an informal policy or protocol was
    prescribed by law.4
    4
    Judge Tatel argues that the four state execution protocols at issue
    in this case are in fact part of the “manner prescribed by the law of
    the State” because they were adopted pursuant to state statutes that
    “delegate to state prison officials the task of developing specific
    execution procedures.” Dissenting Op. 2. In other words, because
    8
    In light of the FDPA’s requirement that the manner of
    execution be prescribed by state “law,” the district court’s
    expansive interpretation of Section 3596(a) fails because it
    includes state procedures regardless of whether they are part of
    state “law.” See Matter of Fed. Bureau of Prisons’ Execution
    Protocol Cases, No. 12-CV-0782, 
    2019 WL 6691814
    , at *6
    (D.D.C. Nov. 20, 2019) (citing informal execution policies
    from Texas, Missouri, and Indiana). The FDPA simply does
    not require the U.S. Marshal to follow aspects of a state
    execution procedure that were not formally enacted or
    promulgated. “[P]rescribed by the law of the State” sets an
    outer boundary on what the federal government must follow.
    On the other hand, the statutory command also means that the
    federal government cannot look only to the “method” of
    execution prescribed by the state. The interpretation adopted
    by Judge Katsas and the government does not account for other
    details that might be included in state law and formal
    regulations. While, as discussed below, formal state law often
    “‘by law,’ each state directed its prison officials to develop execution
    procedures, and ‘by law,’ those officials established such procedures
    and set them forth in execution protocols,” Judge Tatel contends that
    the protocols are subsumed within the phrase “prescribed by … law.”
    
    Id.
     at 4–5. Yet neither the Supreme Court nor our court has ever
    adopted such a capacious understanding of “law.” Instead, the
    Supreme Court has directed that we ask whether a protocol has the
    “force and effect of law,” Chrysler, 
    441 U.S. at
    295–96, and not
    everything an official does pursuant to his statutory authority carries
    the force of law. For instance, agencies issue interpretive rules
    pursuant to their statutory authority, yet interpretive rules
    emphatically do not carry the force of law. See, e.g., Perez v. Mortg.
    Bankers Ass’n, 
    575 U.S. 92
    , 97 (2015). Indeed, the Supreme Court
    explicitly said in Chrysler that neither “[a]n interpretive regulation
    [nor] general statement of agency policy” can be considered an
    “authorization by law” because they lack “the binding effect of law.”
    
    441 U.S. at
    315–16 (alterations omitted).
    9
    specifies little more than the method of execution, the federal
    government is nonetheless bound by the FDPA to follow the
    level of detail prescribed by state law.5
    The textual context of Section 3596(a) supports this
    interpretation. Section 3596(a) provides that the Marshal “shall
    supervise implementation of the sentence in the manner
    prescribed by the law of the State.” 
    18 U.S.C. § 3596
    (a)
    (emphasis added). This broad language encompasses more than
    earlier federal death penalty statutes, which incorporated state
    law only to define the “manner of inflicting the punishment of
    death.” See An Act to Provide for the Manner of Inflicting the
    Punishment of Death § 323, 
    50 Stat. 304
    , 304 (June 19, 1937);
    An Act for the Punishment of Certain Crimes § 33, 
    1 Stat. 112
    ,
    119 (Apr. 30, 1790). The ordinary meaning of “implementation
    of the sentence” includes more than “inflicting the punishment
    of death.” The latter refers to the immediate action of
    execution, whereas “implementation of the sentence” suggests
    5
    Judge Katsas claims that the “participial phrase ‘prescribed by the
    law of the State’ functions as an adjective,” and adjectives usually
    “do not expand the meaning of the noun they modify.” Concurring
    Op. 19 (Katsas, J.). This argument begs the question: It makes sense
    only if we presume that the word “manner” refers exclusively to the
    general method. But there is no evidence of such an exclusive
    meaning. Rather, as cases and statutes demonstrate, the word
    “manner” is broad enough to encompass execution procedures at
    every level of generality. The phrase “prescribed by the law of the
    State” actually narrows the meaning of the word “manner.” Thus,
    my reading is consistent with the most common grammatical
    function of a participial phrase.
    10
    additional procedures involved in carrying out the sentence of
    death.6
    In the death penalty context, the term “implementation” is
    commonly used to refer to a range of procedures and
    safeguards surrounding executions, not just the top-line
    method of execution. This is true of DOJ’s regulations, which
    were promulgated during a period when no statute specified
    procedures for the federal death penalty. DOJ’s 1993 execution
    regulation bears the title, “Implementation of Death Sentences
    in Federal Cases.” See 
    58 Fed. Reg. 4,898
     (Jan. 19, 1993). That
    regulation governs very minute aspects of executions,
    including the “[d]ate, time, place, and method,” whether and
    when the prisoner has access to spiritual advisors, and whether
    photographs are allowed during the execution. 
    Id. at 4
    ,901–
    902. Likewise, the 2019 addendum to DOJ’s execution
    protocol, which governs some of the procedures at issue in this
    case, is titled, “Federal Death Sentence Implementation
    Procedures.” Department of Justice, Addendum to BOP
    Execution Protocol, Federal Death Sentence Implementation
    Procedures 1 (July 25, 2019) (“BOP Addendum”). As with the
    1993 regulation, the addendum governs minute details, such as
    the numbering and labeling of syringes. 
    Id. at 2
    . According to
    DOJ regulations and protocols, all of these details fall under the
    umbrella of implementing a death sentence. The breadth of the
    term “implementation” further undermines the government’s
    narrow interpretation that “manner” means only the “method”
    of execution, irrespective of the requirements of state law.

    Compare Implementation Plan, Black’s Law Dictionary (10th ed.
    2014) (“An outline of steps needed to accomplish a particular goal.”),
    with Inflict, Merriam-Webster’s Collegiate Dictionary (11th ed.
    2014) (“[T]o cause (something unpleasant) to be endured.”).
    11
    An interpretation requiring the federal government to
    follow all procedures prescribed by state statutes and formal
    regulations, but no more, similarly coheres with the statute’s
    directive that the Marshal “supervise” implementation of the
    sentence. 
    18 U.S.C. § 3596
    (a). To “supervise” is to
    “superintend” or “oversee.” See Supervise, Merriam Webster’s
    Collegiate Dictionary (11th ed. 2014). The concept of
    supervision does not fit with DOJ’s position that it may
    establish a uniform protocol for all procedures short of the
    method of execution specified by state law. In the context of
    executing the law, supervision must occur within legal
    boundaries. While supervision often includes a degree of
    discretion, it does not include authority to create new law or to
    act in contravention of law. See Youngstown Sheet & Tube Co.
    v. Sawyer, 
    343 U.S. 579
    , 588 (1952) (emphasizing that “the
    President’s power to see that the laws are faithfully executed”
    does not include the power to “make laws which the President
    is to execute”). Elsewhere, Congress used more active
    language. In the 1937 statute, for instance, the Marshal was
    “charged with the execution of the sentence,” 50 Stat. at 304,
    and other provisions of the FDPA refer to “carr[ying] out” an
    execution. See 
    18 U.S.C. § 3596
    (b), (c). Congress’s choice in
    Section 3596(a) to provide only that the Marshal will
    “supervise” implementation hardly suggests that DOJ was
    given the authority to dictate nearly every aspect of the
    execution procedure regardless of what state law prescribes.
    At the same time, the statute’s use of “supervise” suggests
    that the Marshal enjoys a certain degree of discretion in the
    absence of state law on a particular question. If the FDPA had
    provided only that the Marshal “shall implement” the sentence
    according to state law, there would be less support for the idea
    that the Marshal has discretion to fill gaps in a state’s execution
    law. Instead, the statute affords the Marshal a measure of
    supervisory discretion within the bounds of state law.
    12
    The FDPA specifies one exception to the general rule that
    the federal government must follow state law—the federal
    government may choose state or federal facilities for
    executions, irrespective of state law. Section 3597(a) addresses
    the question of where executions will take place and which
    facilities the Marshal may use. It provides that the Marshal
    “may use appropriate State or local facilities,” so long as the
    Marshal “pay[s] the costs thereof.” 
    18 U.S.C. § 3597
    (a). This
    language establishes that the Marshal has discretion to choose
    between state and federal facilities, notwithstanding any state
    law requiring executions in a particular location. Under
    familiar canons of construction, the more specific provision
    controls the general. See RadLAX Gateway Hotel, LLC v.
    Amalgamated Bank, 
    566 U.S. 639
    , 645 (2012) (noting this
    canon “is a commonplace of statutory construction” (citation
    omitted)). Section 3596(a) directs the government to follow a
    state’s death penalty law generally, while Section 3597(a) is
    best read as an exception, specifying one aspect of the
    execution process by allowing the federal government a choice
    of location. See id.7
    Finally, this fuller reading of the statutory text coheres
    with the FDPA and the apparent balance Congress struck
    between providing for a federal death penalty and respecting
    provisions of state law. If “prescribed by the law of the State”
    includes only a state’s statutes and formal regulations, the
    Marshal will be able to identify the requirements of state law.
    Nothing in the FDPA suggests that the federal government
    must incorporate most or all procedures and practices found in
    a state’s informal execution policies, which could raise
    practical, and perhaps insurmountable, difficulties to the
    7
    While it is true that Section 3597 is not written explicitly as an
    exception, see Concurring Op. 13 (Katsas, J.), it provides specific
    authority that supersedes the general reliance on state law.
    13
    implementation of federal death sentences. For instance, at
    least some state protocols are not publicly available. See 
    Ark. Code Ann. § 5-4-617
    (i)(1)(C). Others are “revised as needed”
    through informal means. See Indiana State Prison Facility
    Directive, ISP 06-26: Execution of Death Sentence 14 (Jan. 22,
    2014). When Congress used the term “prescribed by the law of
    the State,” it did not mean secret policies and constantly
    changing informal protocols.8
    In this politically charged area, Congress enacted a
    federalist scheme, incorporating state law as to the “manner”
    of death penalty implementation, but only for those execution
    procedures enacted or promulgated by states as part of their
    binding law. The FDPA leaves the federal government free to
    specify details regarding execution procedures, as it did in its
    protocol and addendum, subject to any contrary requirements
    of state law.
    8
    This interpretation is largely consistent with other courts to have
    considered the issue. The Fifth Circuit upheld a death sentence under
    an earlier version of DOJ’s protocol because nothing in the protocol
    was “inconsistent with Texas law.” United States v. Bourgeois, 
    423 F.3d 501
    , 509 (5th Cir. 2005). The only source of law the court
    considered was Texas’s criminal code, 
    id.,
     which does not provide
    for specific procedures or designate a lethal substance. See Tex. Code
    Crim. Proc. Ann. art. 43.14. Similarly, the District of Vermont held
    that a U.S. Marshal is “to adopt local state procedures for execution,”
    but the court looked only to state statutes in defining the state’s
    procedures. See United States v. Fell, No. 5:01-CR-12-01, 
    2018 WL 7270622
    , at *4 (D. Vt. Aug. 7, 2018); but see Higgs v. United States,
    
    711 F. Supp. 2d 479
    , 556 (D. Md. 2010) (declining to reach the
    Section 3596(a) question, but briefly suggesting in dicta that
    “manner” refers only to lethal injection).
    14
    B.
    DOJ attempts to use previous federal death penalty statutes
    to show that “manner” must mean “method.” A review of these
    statutes, however, demonstrates that Congress was at best silent
    as to whether the word had a specialized meaning. Prior federal
    execution statutes support neither the government’s “manner
    means method only” interpretation, nor the plaintiffs’ “manner
    means everything” interpretation. Rather, the history shows
    Congress uses “manner” in its ordinary sense, such that the
    scope of the term’s application depends on the context.
    There were only two federal statutes regulating execution
    procedures prior to the FDPA, and neither suggested that
    “manner” refers exclusively to general methods. The first
    federal death penalty statute, passed in 1790, read, “the manner
    of inflicting the punishment of death, shall be by hanging the
    person convicted by the neck until dead.” § 33, 1 Stat. at 119.
    That provision is entirely consistent with my interpretation:
    Congress, using a broad word that can refer to any level of
    generality, chose on that occasion not to mandate further
    details. In another section of the same statute Congress used the
    word “manner” in a highly granular sense. The 1790 statute
    criminalized the maiming of a person in any of six enumerated
    “manners”—a list so particularized that “slit[ting] the nose”
    and “cut[ting] off the nose” were listed separately. § 13, 1 Stat.
    at 115. Reading the 1790 statute as a whole, Congress used the
    word “manner” to refer to both general methods and specific
    details, reinforcing that the term “manner” in isolation has a
    flexible meaning and must be read in context to determine the
    appropriate level of specificity.
    Judge Katsas argues that the 1790 statute should be read
    against the backdrop of English common law. Concurring Op.
    4 (Katsas, J.). As he notes, Blackstone wrote that the
    15
    punishment for many capital crimes was to be “hanged by the
    neck till dead.” 4 W. Blackstone, Commentaries on the Laws
    of England 370 (1769). Notably, Blackstone does not say that
    hanging by the neck was the “manner” of execution. He says
    that hanging was the “judgment” pronounced by the court. Id.
    Indeed, this passage never uses the word “manner.” Later,
    Blackstone wrote that a “sheriff cannot alter the manner of the
    execution by substituting one death for another.” Id. at 397.
    Nor could the king substitute one death for another—for
    instance, by “altering the hanging or burning into beheading.”
    Id. at 397–98. Nothing in this passage suggests that the choice
    of general method was the only detail encompassed by the term
    “manner of the execution.” At most, this passage shows that
    changing the general method was one way to change the
    manner of execution.
    Judge Katsas’s reliance on two Supreme Court cases from
    the nineteenth century is similarly unavailing. First, Wilkerson
    v. Utah, 
    99 U.S. 130
     (1878), simply paraphrased the language
    of the 1790 statute, see 
    id. at 133
     (“Congress provides that the
    manner of inflicting the punishment of death shall be by
    hanging.”), so it adds no support for the narrow reading of
    “manner.” Next, Judge Katsas argues that the Supreme Court
    used “manner” and “method” interchangeably in Kemmler, 
    136 U.S. 436
    . Yet nothing in the Court’s opinion indicates that the
    two terms are synonymous. To the contrary, the opinion
    strongly suggests that the term “manner” encompasses more
    than the general method. In rejecting a petition for habeas
    corpus, the Court quoted the New York Court of Appeals at
    length, including its conclusion that the general method of
    electrocution is painless—not necessarily as a general matter,
    but when performed “under such conditions and in the manner
    contemplated by the statute.” 
    Id.
     at 443–44 (“[T]he application
    of electricity to the vital parts of the human body, under such
    conditions and in the manner contemplated by the statute, must
    16
    result in instantaneous, and consequently in painless, death.”
    (citation omitted)). The term “manner” in that sentence must
    refer to details more specific than the general method of
    electrocution. Id.9 Even if at points Wilkerson and Kemmler
    refer to hanging and electrocution as manners of execution,
    they are still consistent with the ordinary meaning of “manner,”
    which can refer to the general and the specific. It is not unusual
    for courts to refer to hanging or lethal injection as manners of
    execution, just as courts commonly use “manner” to refer to
    specific details of an execution procedure. See supra at 4–5.
    The government also relies on the 1937 statute to argue
    that “manner” is used in the FDPA to refer only to the method
    of execution. See DOJ Br. 21–22 (“Congress [in 1937]
    preserved the meaning of ‘the manner’ as synonymous with
    ‘the method’ of execution.”). In the 1937 statute, Congress
    shifted away from the earlier federal death penalty regime to
    one that required the federal government to adopt whatever
    “manner” was “prescribed by the laws of the State.” 50 Stat. at
    304. The 1790 and 1937 statutes thus had different structures,
    one specifying a single method of federal execution and the
    other leaving the manner of execution to be determined by state
    law. This fundamental change to the statutory scheme
    undermines DOJ’s contention that Congress forever settled the
    9
    I agree with Judge Katsas that the level of detail in the New York
    statute is not relevant in itself. Concurring Op. 6 n.2 (Katsas, J.); see
    also Chapter 489, Laws of the State of New York §§ 492, 505–07
    (June 4, 1888) (regulating execution timing, location, and personnel,
    among other things). Indeed, my analysis consistently maintains that
    the meaning of the word “manner” does not change whenever a
    legislature chooses to specify more or less detail in a given statute,
    whether a state statute or the FDPA. Regardless of how detailed the
    statute was, the Supreme Court in Kemmler used the word “manner”
    to encompass more than the general method of electrocution. See 
    136 U.S. at
    443–44.
    17
    scope of federal death penalty legislation in 1790 when it chose
    hanging as the method of execution. Indeed, the fact that
    Congress amended the legally operative text suggests that the
    1937 Act did not use “manner” in precisely the same way as
    the 1790 statute. See Hall v. Hall, 
    138 S. Ct. 1118
    , 1128 (2018)
    (stating that a statute “brings the old soil with it” only when
    “obviously transplanted”); Merrill Lynch, Pierce, Fenner &
    Smith Inc. v. Manning, 
    136 S. Ct. 1562
    , 1578 (2016) (Thomas,
    J., concurring) (“[W]hen Congress enacts a statute that uses
    different language from a prior statute, we normally presume
    that Congress did so to convey a different meaning.”).
    Statutory predecessors can help us to interpret a modern statute,
    but we must respect the changes Congress enacted.
    For the same reasons discussed with respect to the FDPA,
    the phrase “manner prescribed by the laws of the State” in the
    1937 statute is best read as referring to all execution procedures
    found in the state’s “law.” In practice, moreover, the federal
    government incorporated more than the state’s method of
    execution when it carried out executions under the 1937 statute.
    The government concedes that nearly all executions conducted
    under the 1937 statute took place in state facilities. Oral
    Argument at 3:30. Presumably, those executions were carried
    out in accordance with state law and possibly with other state
    procedures. DOJ notes that three executions under the 1937
    statute took place in federal facilities, but DOJ is unable to
    identify a single way in which the executions were otherwise
    inconsistent with state law. As in the FDPA, the 1937 statute
    gave the U.S. Marshal discretion over the choice of facilities.
    See 50 Stat. at 304. Thus, the choice of a federal location does
    not undermine the requirement that the manner of execution
    follow whatever details are prescribed by state law.
    Not only did the federal government perform the vast
    majority of executions in state prisons, DOJ has suggested on
    18
    several occasions that it understood the 1937 statute to require
    compliance with state procedures. In its 1993 protocol, DOJ
    hypothesized that Congress might have repealed the 1937
    statute because it “no longer wanted the federal method of
    execution dependent on procedures in the states, some of which
    were increasingly under constitutional challenge.” 58 Fed. Reg.
    at 4,899 (discussing repeal of the 1937 statute in 1984).
    Similarly, Attorney General Janet Reno wrote shortly before
    the FDPA’s enactment that the bill “contemplate[s] a return to
    an earlier system in which the Federal Government does not
    directly carry out executions, but makes arrangements with
    states to carry out capital sentences in Federal cases.” See H.R.
    Rep. No. 104-23, at 22 (1995) (quoting Letter from Attorney
    General Janet Reno to Hon. Joseph R. Biden, Jr., at 3–4 (June
    13, 1994)). While such sources are not determinative of the
    meaning of the FDPA, they demonstrate that the Department’s
    narrow interpretation of the statute has hardly been
    consistent.10
    10
    Judge Katsas also argues that between 1790 and 1937, “nobody
    [was] focused on subsidiary procedural details in the legal or policy
    debates over [] various execution methods.” Concurring Op. 7
    (Katsas, J.). Even assuming that assessment is correct, it has no
    bearing on the broader sense of “manner” or how it was used in the
    FDPA. This observation would be relevant only to the meaning of
    “manner” in statutes that do not specify the scope of the term’s
    application. For example, if the FDPA said something like “the
    manner employed by the state,” then we would have to determine, as
    Judge Katsas asks, “the level of detail at which [Section 3596(a)]
    operates.” Id. at 1. Yet the FDPA explicitly specifies the level of
    detail—it is the level of detail “prescribed by the law of the State.”
    That leaves a question of what is included in the “law of the state,”
    but it does not leave open the level of generality regarding the
    manner of execution.
    19
    Despite rejecting DOJ’s historical evidence, I start from
    the same fundamental principle: that we should not “depart
    from the original meaning of the statute at hand.” New Prime
    Inc. v. Oliveira, 
    139 S. Ct. 532
    , 539 (2019). As explained, the
    meaning of the word “manner” has always been broad, and its
    application has always depended on context. DOJ, however,
    asks us to go beyond established canons of interpretation:
    Rather than apply the original, broad sense of the word
    “manner,” DOJ argues that the word should be deprived of its
    ordinary meaning because Congress chose on a single occasion
    in 1790 to specify one level of detail. There is no support for
    this novel approach.
    In statutory interpretation as in ordinary usage, a word can
    have a fixed meaning even if, in application, it can refer to a
    variety of things. DOJ is confusing the sense of the word
    “manner” with the word’s reference. A word’s sense is its
    linguistic meaning, while its reference is the “actual thing in
    the world that the word picks out.” Christopher R. Green,
    Originalism and the Sense-Reference Distinction, 
    50 St. Louis U. L.J. 555
    , 563 (2006). A single word with a fixed meaning
    can describe a wide range of references, depending on the
    factual context and how the word is used. See 
    id. at 564
    ; cf.
    ConFold Pac., Inc. v. Polaris Indus., Inc., 
    433 F.3d 952
    , 957–
    58 (7th Cir. 2006) (explaining that the term “unjust
    enrichment” has multiple “referents” because it can refer to
    several factually distinct circumstances in which restitution is
    appropriate).11 Rather than explore what the word “manner”
    11
    Judge Katsas’s only linguistic critique of the sense-reference
    distinction is that sense and reference arguably converge when
    dealing with proper names, Concurring Op. 8 n.3 (Katsas, J.),
    something that is completely irrelevant to this case. We both agree
    with Justice Scalia (and Professor Green, for that matter) that statutes
    have “a fixed meaning, which does not change.” 
    Id.
     That recognition
    20
    meant in 1790 (i.e., what sense it carried), DOJ focuses
    narrowly on which procedures Congress chose to require on
    one occasion (i.e., the reference of “manner”). According to
    DOJ, the word “manner” in 1994 cannot be broad enough to
    refer to specific procedures unless the 1790 statute also referred
    to specific procedures. But Congress’s choice not to specify
    details like the length of the rope did not change the underlying
    meaning of the word “manner.” The word “manner” was broad
    enough in 1790 to encompass more than the general method (as
    demonstrated by the statute’s discussion of maiming), and the
    word retains that broad sense today. There is simply no reason
    to artificially cabin the word in later statutes so that it refers
    only to the same kinds of procedures required by Congress in
    1790.
    DOJ’s ahistorical reading is also flatly inconsistent with
    the canons of interpretation governing incorporation. When
    Congress incorporates a body of law in general terms, the
    incorporating statute “develops in tandem with the” body of
    law that was incorporated. Jam v. Int’l Fin. Corp., 
    139 S. Ct. 759
    , 769 (2019); see also New Prime Inc., 139 S. Ct. at 539;
    2B Sutherland Statutory Construction § 51:8 (7th ed.). For
    most of the last 80 years, Congress has chosen to incorporate
    state law rather than specify a manner of execution. As Judge
    Katsas explains, it was once true that most execution statutes
    did not “prescribe subsidiary ‘procedural details.’” Concurring
    Op. 6 (Katsas, J.). Today, however, some “state statutes and
    regulations do contain many granular details.” Id. at 21. When
    a state legislature chooses to define the manner of execution in
    more detail than was common in older statutes, the FDPA
    directs the federal government to follow suit. See New Prime
    does nothing to undermine the commonly accepted distinction
    between a word’s meaning and the thing the word refers to on a given
    occasion.
    21
    Inc., 139 S. Ct. at 539 (explaining that statutes incorporating a
    general body of law must be read to incorporate “later
    amendments and modifications”).12
    The historical record is likewise inconsistent with the
    plaintiffs’ assertion that the FDPA does not allow DOJ to adopt
    nationwide procedures. See Plaintiffs’ Br. 23–24. It is true that
    Congress in 1937 replaced a uniform, nationwide approach
    with a requirement that the federal government follow the
    sentencing state’s manner of execution. Nevertheless, neither
    the 1937 statute nor the FDPA requires that the federal
    government follow state practices not prescribed by law. The
    statutory history thus says nothing about whether the
    Department can create uniform procedures to fill gaps in state
    law, as the protocol and addendum do in this case.
    12
    Failing to find support in the FDPA’s text, history, or practice, DOJ
    tries to prop up its arguments with the 1937 statute’s legislative
    history. This legislative history, however, did not run the Article I,
    section 7, gauntlet, and cannot determine a statute’s meaning. Even
    for those who find legislative history persuasive, the evidence is thin.
    DOJ explains that the House Judiciary Committee twice used the
    word “method” to refer to executions by hanging, electrocution, and
    gas. H.R. Rep. No. 75-164, at 1 (1937). DOJ argues that because the
    Committee changed the word “method” to “manner” in the statute, it
    must have understood the two words to be synonymous. Yet the
    legislative history is silent about why the Committee made that
    choice in the final text of the FDPA. If we are playing the legislative
    history guessing game, another inference is perhaps more likely: that
    Congress chose to use a different word in order to convey a different
    meaning. Cf. Allina Health Servs. v. Price, 
    863 F.3d 937
    , 944 (D.C.
    Cir. 2017). Ultimately, however, legislative history is not the law,
    and the history from 1937 tells us little about what the 1937 statute
    meant, much less what the 1994 FDPA means.
    22
    In sum, the historical evidence does not suggest the term
    “manner” has the narrow meaning pressed by DOJ; neither
    does it support the plaintiffs’ conclusion that the federal
    government may not create national procedures that govern in
    the absence of any state law. Rather, for over 200 years,
    Congress has used the term “manner” flexibly, with the word’s
    scope clarified by additional specifying language—“hang[ing]
    by the neck,” slit[ting] the nose, and “prescribed by the law of
    the State.” In light of this history, the best interpretation follows
    the plain meaning of the FDPA, which specifies that “manner”
    is whatever is prescribed by state law. This interpretation
    respects Congress’ decision to create a federal death penalty
    that relies on federalism. The FDPA requires DOJ to follow the
    procedures set forth in state laws and regulations but does not
    foreclose federal protocols that apply in areas not addressed by
    state law.
    C.
    The Department raises a parade of horribles if “manner” is
    read to include more than the method of execution.
    Specifically, DOJ argues that a broader reading will make it
    much more difficult to execute prisoners and will leave the
    federal government unable to choose the most humane
    execution procedures. The government’s purpose-driven
    arguments rely on broad policy goals and practical difficulties,
    rather than the plain meaning of the text. These policy
    arguments, however valid, cannot overcome Congress’s plain
    choice in the FDPA to allow the manner of execution to turn
    on state law.13
    13
    Judge Katsas suggests that arguments about consequences are
    relevant to “help resolve textual ambiguity.” Concurring Op. 16 n.8
    (Katsas, J.). Yet the word “manner” as used in Section 3596 is not
    23
    DOJ’s concerns are rooted in what the Department deems
    to be the purposes of the FDPA. DOJ Br. 15; see also
    Concurring Op. 13 (Katsas, J.) (discussing one purpose of the
    FDPA “to ensure a workable and expanded system of capital
    punishment”). As a court, however, “our function [is] to give
    the statute the effect its language suggests,” not to further
    whatever “admirable purposes it might be used to achieve.”
    Morrison v. Nat’l Australia Bank Ltd., 
    561 U.S. 247
    , 270
    (2010). DOJ urges us to give the FDPA the interpretation
    producing what it believes would be the most effective
    execution regime, but to do so would ignore both the limited
    nature of our judicial function and the realities of legislative
    deliberation:
    [N]o legislation pursues its purposes at all costs.
    Deciding what competing values will or will not
    be sacrificed to the achievement of a particular
    objective is the very essence of legislative
    choice—and it frustrates rather than effectuates
    legislative intent simplistically to assume that
    whatever furthers the statute’s primary
    objective must be the law.
    Pension Ben. Guar. Corp. v. LTV Corp., 
    496 U.S. 633
    , 646–47
    (1990) (citation and quotation marks omitted).
    ambiguous. Rather, as already explained, the ordinary meaning of
    the word “manner” is broad and flexible, but as qualified in the
    FDPA, the “manner” of execution is unambiguous: It is whatever
    “manner” is prescribed by applicable state law. See supra at 6–8; see
    also Diamond v. Chakrabarty, 
    447 U.S. 303
    , 315 (1980) (“Broad
    general language is not necessarily ambiguous”). Speculations about
    congressional intent are rarely illuminating, particularly when, as
    here, the text of the statute provides the relevant level of specificity.
    24
    In the FDPA, Congress incorporated state law instead of
    directing DOJ to promulgate a uniform protocol. This suggests
    that Congress was balancing at least two competing values: the
    need to effectively implement federal death sentences and an
    interest in federalism. Perhaps Congress simply decided to
    duck controversial specifics by leaving some questions to state
    law. Whatever the reason, statutes strike a bargain and must be
    enforced in their details, not in their lofty goals. After all, “[i]f
    courts felt free to pave over bumpy statutory texts in the name
    of more expeditiously advancing a policy goal, we would risk
    failing to take account of legislative compromises essential to
    a law’s passage and, in that way, thwart rather than honor the
    effectuation of congressional intent.” New Prime Inc., 139 S.
    Ct. at 543 (quotation marks and alterations omitted). We should
    decline DOJ’s invitation to question the bargain Congress
    struck here. To the extent more detailed state statutes raise
    additional interpretive questions, that is an unavoidable
    consequence of the incorporation of state law. Unless and until
    Congress amends the FDPA, DOJ is bound to “follow its
    commands as written, not to supplant those commands with
    others it may prefer.” SAS Inst., Inc. v. Iancu, 
    138 S. Ct. 1348
    ,
    1355 (2018). We have no license to read into the FDPA a
    limitation on “manner” that has no basis in the text and to read
    out of the statute its incorporation of state law.
    In addition, DOJ’s policy concerns about administrability
    would have applied with equal force in 1937, when Congress
    first incorporated state law to govern the manner of federal
    executions. See New Prime Inc., 139 S. Ct. at 539 (“[I]t’s a
    fundamental canon of statutory construction that words
    generally should be interpreted as taking their ordinary ...
    meaning ... at the time Congress enacted the statute.”
    (quotation marks omitted)). In 1937, permissible execution
    methods varied significantly across the country and included
    hanging, electrocution, the gas chamber, and others. State
    25
    execution methods also differed, albeit to a lesser extent, when
    the FDPA was passed in 1994. Thus, even under DOJ’s
    interpretation that “manner” means only method, until recently
    the federal government would have had to apply varying
    execution methods on a state-by-state basis. DOJ claims that
    state-by-state administration is unworkable, but state-by-state
    administration has indisputably been a feature of this statutory
    framework since 1937. A uniform method is possible under
    DOJ’s interpretation only because all the death penalty states
    have made independent choices since the FDPA’s enactment
    to adopt the method of lethal injection.
    Similarly, the federal government has never had absolute
    license to choose the most humane execution procedures.
    When Congress passed the 1937 statute, it chose state practice
    over hanging in part because “[m]any States”—but not all—
    “use[d] more humane methods of execution, such as
    electrocution, or gas.” H.R. Rep. No. 75-164, at 1 (1937).
    Congress could have selected one of those more humane
    methods instead of hanging, but it chose to leave that decision
    to the states—many of which continued to hang criminals. See
    Andres v. United States, 
    333 U.S. 740
    , 745 (1948) (noting that
    the “method of inflicting the death penalty” in Hawaii in 1948
    was “death by hanging”). Indeed, some states continued to
    provide for hanging even after the passage of the FDPA in
    1994. See Baze, 
    553 U.S. at
    43 n.1 (plurality opinion) (noting
    that New Hampshire and Washington still allowed for hanging
    in 2008). Even under DOJ’s interpretation of the FDPA, the
    government may choose what it considers to be the most
    humane procedures only when state law does not provide for
    another method of execution. Whatever the legitimacy of
    26
    DOJ’s concerns, they are necessary features of the statute
    Congress enacted.14
    In any event, as a practical matter, my textual
    interpretation of the FDPA mitigates many of the concerns
    raised by the district court’s broad reading. The FDPA’s
    reliance on state law leaves ample scope for DOJ to follow its
    federal execution procedures and protocols. Few of the
    procedural details cited by the plaintiffs appear to carry the
    force of law, so the federal government need not follow them.
    State execution statutes tend to be rather brief, specifying lethal
    injection without adding further details. For example, none of
    the four states at issue in this case have statutes precluding the
    use of pentobarbital. See Tex. Code Crim. Proc. Ann. art. 43.14
    (calling for lethal injection without specifying which chemical
    to be used); 
    Ark. Code Ann. § 5-4-617
     (allowing lethal
    injection using either a barbiturate like pentobarbital or a three
    drug solution); 
    Ind. Code § 35-38-6-1
     (calling for lethal
    injection without specifying which chemical must be used);
    
    Mo. Ann. Stat. § 546.720
     (calling for lethal injection without
    specifying which chemical must be used).
    14
    Like the DOJ, Judge Tatel invokes the FDPA’s goal of ensuring
    more humane executions, but to support the opposite interpretation.
    He argues that reading “prescribed by the law of the State” to exclude
    non-binding state execution protocols would “defeat section
    3596(a)’s purpose—to make federal executions more humane by
    ensuring that federal prisoners are executed in the same manner as
    states execute their own.” Dissenting Op. 8. Yet that argument
    deprives the phrase “prescribed by … law” of all meaning. If
    Congress had intended the federal government to incorporate all of
    the state’s execution procedures, it would have said so. Instead,
    Congress chose to incorporate only the manner prescribed by state
    law.
    27
    Indeed, I have not been able to locate statutes or formal
    regulations in any state that would prevent the federal
    government from using pentobarbital, the drug currently
    specified in DOJ’s protocol addendum. In the rare cases where
    state law provides for a particular substance, states generally
    either include pentobarbital on the list of permitted substances,
    see 
    501 Ky. Admin. Regs. 16
    :330 (allowing either
    pentobarbital or thiopental sodium), or include a general
    provision allowing any equally effective substance, see 
    Utah Admin. Code r. 251-107-4
     (providing for “a continuous
    intravenous injection, one of which shall be of a lethal quantity
    of sodium thiopental or other equally or more effective
    substance to cause death”).
    More specific details are generally found in informal state
    policies and protocols. Execution protocols are exempted from
    many states’ administrative procedure acts, including their
    formal rulemaking requirements. See, e.g., 
    Ark. Code Ann. § 5
    -
    4-617(h); Middleton v. Mo. Dep’t of Corr., 
    278 S.W.3d 193
    ,
    195–97 (Mo. 2009); Porter v. Commonwealth, 
    661 S.E.2d 415
    ,
    432–33 (Va. 2008); Abdur’Rahman v. Bredesen, 
    181 S.W.3d 292
    , 312 (Tenn. 2005). Even in states that provide for formal
    rulemaking, execution protocols tend to be informal and non-
    binding. Consider Indiana, the state designated by DOJ
    whenever the sentencing state does not provide for the death
    penalty. Indiana allows its department of corrections to adopt
    rules under the state’s formal rulemaking provisions to
    implement its execution statute. See 
    Ind. Code § 35-38-6-1
    (d).
    Yet the state’s current execution procedures were not
    promulgated under that statute and do not purport to carry the
    force of law. See Indiana State Prison Facility Directive, ISP
    06-26: Execution of Death Sentence 14 (Jan. 22, 2014) (noting
    that Indiana’s protocol is “revised as needed,” not under the
    state’s formal rulemaking procedures, but in accordance with
    the department of corrections’ policies). Similarly, both
    28
    Arkansas’ and Missouri’s protocols permit the director of the
    department of corrections to modify certain aspects of the
    execution procedures. See Missouri Department of
    Corrections, Preparation and Administration of Chemicals for
    Lethal Injection 1 (Oct. 18, 2013); Arkansas Lethal Injection
    Procedure 3 (Aug. 6, 2015), https://bit.ly/2ExLkTE. A state
    execution protocol that explicitly allows the department of
    corrections to depart from the protocol’s requirements on a
    case-by-case basis cannot be said to be binding. Given that
    most details found in state execution protocols are not
    prescribed by law, DOJ will be able to make most procedural
    choices regarding federal executions.15
    II.
    Based on this interpretation of Section 3596(a), I would
    hold that the 2019 protocol did not exceed the government’s
    authority under the FDPA. As an initial matter, the protocol is
    unlikely to conflict with state law in most cases, as state laws
    15
    Judge Tatel does not dispute that the four protocols at issue were
    not promulgated through formal rulemaking procedures. Instead, he
    attempts to cabin Chrysler’s holding to its facts, ignores the
    consistent line of cases requiring “law” to have binding effect, see
    supra at 7 (collecting cases), and makes a general appeal to
    examining “context” when determining whether a regulation issued
    outside a formal rulemaking process constitutes “law.” Dissenting
    Op. 7–8. Judge Tatel, however, fails to identify a single case
    supporting his theory that non-binding protocols can qualify as “law”
    in any context—despite the fact that, as Judge Tatel emphasizes,
    “prescribed by law” or similar language appears at least 1,120 times
    in the United States Code. Id. at 7. As the Court explained in
    Chrysler, the question is simply whether these state protocols are
    binding on state officials. Because these protocols do not appear to
    have the binding force of law, they cannot be deemed part of the “law
    of the State.”
    29
    usually address execution procedures only in general terms.
    See supra at 24–26. Should cases arise in which the protocol
    differs from state law—for example, in states with more
    detailed regulations governing executions, see, e.g., 
    501 Ky. Admin. Regs. 16
    :330; 
    Or. Admin. R. 291
    -024-0080—DOJ
    remains free to depart from the federal protocol. Indeed, the
    protocol provides explicitly that the Director may depart from
    its procedures in the face of superseding legal obligations—
    namely, when “necessary” to “comply with specific judicial
    orders” or when “required by other circumstances.” BOP
    Addendum 1; see also Department of Justice, BOP Execution
    Protocol 4 (2019) (“Execution Protocol”) (“These procedures
    should be observed and followed as written unless deviation or
    adjustment is required ….”). In addition, the protocol directs
    BOP to “make every effort … to ensure the execution process
    … [f]aithfully adheres to the letter and intent of the law.”
    Execution Protocol 4–5. These provisions indicate that the
    government must depart from the protocol as necessary to
    “adhere to the letter and intent of” the FDPA—including the
    requirement that the government apply the manner of execution
    prescribed by state law. Reading the protocol and addendum as
    a whole suggests that DOJ must follow state law, and not that
    the BOP Director is merely granted “discretion.” Dissenting
    Op. 9. Because the 2019 protocol allows departures as needed
    to comply with state law, it is consistent with the FDPA.
    Judge Tatel casts this reading of the protocol’s plain text
    as an improper effort to “rewrite the protocol” to support an
    interpretation that the government has not advanced.
    Dissenting Op. 10. As an initial matter, my interpretation
    requires no revision—it rests on the words DOJ used in
    promulgating its protocol. Moreover, “[o]ur duty in conducting
    de novo review on appeal is to resolve the questions of law this
    case presents.” Citizens for Responsibility & Ethics in Wash. v.
    FEC, 
    892 F.3d 434
    , 440 (D.C. Cir. 2018). “When an issue or
    30
    claim is properly before the court, the court is not limited to the
    particular legal theories advanced by the parties, but rather
    retains the independent power to identify and apply the proper
    construction of governing law.” Kamen v. Kemper Fin. Servs.,
    Inc., 
    500 U.S. 90
    , 99 (1991); see also U.S. Nat’l Bank of Or. v.
    Indep. Ins. Agents of Am., Inc., 
    508 U.S. 439
    , 446–47 (1993).
    Irrespective of the government’s litigation strategy, the issue
    before us in this case is whether the 2019 protocol exceeds the
    government’s authority under the FDPA, and it is entirely
    appropriate to conduct an independent assessment of all
    relevant materials—including, in particular, the text of the
    protocol—in order to fulfill our duty to say what the law is.
    Because the district court’s order was premised
    exclusively on the plaintiffs’ claim that the protocol was “in
    excess of statutory … authority,” 
    5 U.S.C. § 706
    (2)(C), I would
    vacate the preliminary injunction. I would further hold that the
    2019 protocol is a “rule[ ] of agency organization, procedure,
    or practice” exempt from the APA’s notice and comment
    requirements. See 
    5 U.S.C. § 553
    (b). The plaintiffs maintain
    we should not reach this claim before the district court has
    considered it. It is true that we ordinarily decline to resolve
    claims and arguments not addressed by the district court in
    deciding a preliminary injunction motion. See Sherley v.
    Sebelius, 
    644 F.3d 388
    , 397–98 (D.C. Cir. 2011). But if our
    holding on appeal makes a conclusion “inevitable” then “we
    have power to dispose [of a claim] as may be just under the
    circumstances, and should do so to obviate further and entirely
    unnecessary proceedings below.” Wrenn v. Dist. of Columbia,
    
    864 F.3d 650
    , 667 (D.C. Cir. 2017) (cleaned up); see also 
    28 U.S.C. § 2106
     (granting appellate courts authority to “direct the
    entry of … judgment … as may be just under the
    circumstances”). The plaintiffs’ notice and comment challenge
    rises and falls with the merits of their FDPA claim—that the
    protocol is a procedural rule follows inescapably from my
    31
    conclusion that the protocol does not exceed DOJ’s authority
    under the FDPA. Because the issues are intertwined and the
    plaintiffs’ notice and comment challenge fails under my
    interpretation of the FDPA, it is entirely unnecessary for the
    district court to address this claim on remand.
    “The critical feature of a procedural rule is that it covers
    agency actions that do not themselves alter the rights or
    interests of parties.” Nat’l Min. Ass’n, 758 F.3d at 250
    (quotation marks omitted). By its terms, the protocol does
    nothing to interfere with the Marshal’s ability to comply with
    the FDPA or with the plaintiffs’ right to have their sentences
    implemented “in the manner prescribed by the law of the
    State.” 
    18 U.S.C. § 3596
    (a). To the contrary, the protocol
    simply lays out procedures for the federal government to
    follow in cases where state law does not address some aspect
    of the execution process. It directs the federal government in
    all cases “to ensure the execution process … [f]aithfully
    adheres to the letter and intent of the law,” Execution Protocol
    4–5, which necessarily includes following the FDPA’s
    directive to implement death sentences in conformity with state
    positive law. As such, the protocol cannot be said to “impose
    [any] new substantive burdens,” Aulenback, Inc. v. Fed.
    Highway Admin., 
    103 F.3d 156
    , 169 (D.C. Cir. 1997), or to
    “alter the rights or interests of [affected] parties,” Nat’l Min.
    Ass’n, 758 F.3d at 250 (citation omitted)—rather, any
    substantive burdens are derived from the FDPA and the state
    laws it incorporates.
    Moreover, the procedures outlined in the 2019 protocol
    bear all the hallmarks of “internal house-keeping measures
    organizing [DOJ’s] activities” with respect to preparing for and
    conducting executions. Am. Hosp. Ass’n v. Bowen, 
    834 F.2d 1037
    , 1045 (D.C. Cir. 1987) (citation omitted). The protocol
    and accompanying addendum provide lengthy “checklists for
    32
    pre-execution, execution and post execution procedures,”
    Execution Protocol 4, including matters as specific as
    arranging food services for an inmate’s final meal, id. at 17,
    “open[ing] the drapes covering the windows of the witness
    rooms” during an execution, id. at 24, and announcing the time
    of death “prior to the drapes being closed,” id. at 25. DOJ’s
    decision to promulgate detailed “written guidelines to aid [its]
    exercise of discretion” during the highly sensitive process of
    conducting executions should not come “at the peril of having
    a court transmogrify those guidelines into binding norms
    subject to notice and comment strictures.” Aulenback, 
    103 F.3d at 169
     (citation and quotation marks omitted). Because the
    protocol possesses the essential features of a procedural rule,
    the plaintiffs’ notice and comment challenge also fails.
    I would not reach the plaintiffs’ argument that only the
    U.S. Marshal Service has the authority to promulgate rules
    under the FDPA. The plaintiffs did not develop this argument
    below, so it is forfeited. See Gov’t of Manitoba v. Bernhardt,
    
    923 F.3d 173
    , 179 (D.C. Cir. 2019) (“Absent exceptional
    circumstances, a party forfeits an argument by failing to press
    it in district court.”).16 I would also decline to reach the
    plaintiffs’ claims under the Food, Drug & Cosmetic Act and
    the Controlled Substances Act, which were neither addressed
    by the district court nor pressed by the plaintiffs on appeal.
    Unlike the notice and comment challenge to the protocol, the
    outcome of the FDCA and CSA claims is not plainly dictated
    16
    The evidence Judge Katsas relies on to conclude that this argument
    was not forfeited comes from a chart included in the factual
    background section of one plaintiff’s preliminary injunction motion,
    summarizing the “Details of 2019 Protocol and Concerns That Are
    Implicated.” See Pl.’s Mot. for Prelim. Inj., Roane v. Barr, No. 19-
    mc-0145, at 10 (D.D.C. Sept. 27, 2019). Such “fleeting reference[s]”
    do not a developed legal argument make. Williams v. Lew, 
    819 F.3d 466
    , 471 (D.C. Cir. 2016).
    33
    by my interpretation of the FDPA. Thus, it will be “for the
    district court to determine, in the first instance, whether the
    plaintiffs’ showing on [these claims] warrants preliminary
    injunctive relief.” Sherley, 
    644 F.3d at 398
    .
    TATEL, Circuit Judge, dissenting: Plaintiffs Daniel Lee,
    Wesley Purkey, Alfred Bourgeois, and Dustin Honken do not
    challenge the federal government’s authority to execute them.
    Instead, they argue that the Attorney General’s plan for their
    executions—that is, the federal protocol—conflicts with
    section 3596(a) of the Federal Death Penalty Act of 1994
    (FDPA), 
    18 U.S.C. §§ 3591
     et seq. Section 3596(a) instructs
    U.S. Marshals to carry out federal death sentences by arranging
    for prisoners to be executed “in the manner prescribed by the
    law of the State” in which they were sentenced—or, if that state
    has no death penalty, the law of “another State” “designate[d]”
    by the sentencing judge. 
    Id.
     § 3596(a). Notwithstanding its
    weighty subject matter, then, this case presents a classic
    question under the Administrative Procedure Act: whether an
    agency has acted “in accordance with law.” 
    5 U.S.C. § 706
    (2)(A).
    In defending the federal protocol, the government argues
    that the word “manner” in section 3596(a) refers only to the
    general execution method—e.g., lethal injection—not, as
    plaintiffs argue, to the procedures and techniques used to
    implement that method, e.g., substance administered or dosage.
    Because the government seeks no deference to its interpretation
    of the statute, see Oral Arg. Rec. 5:57–6:00 (confirming this),
    to prevail it must demonstrate not merely that its interpretation
    of section 3596(a) is reasonable, but that it “best effectuates the
    underlying purposes of the statute.” Vanguard Interstate Tours,
    Inc. v. ICC, 
    735 F.2d 591
    , 597 (D.C. Cir. 1984).
    I agree with Judge Rao that the term “manner” refers to
    more than just general execution method. Because her detailed
    opinion so thoroughly addresses the government’s arguments
    and convincingly responds to Judge Katsas’s survey of the
    historical record, I see no need to say anything more on the
    issue.
    2
    Beyond this, Judge Rao and I part company. She would
    hold that when carrying out executions under section 3596(a),
    the Attorney General must comply with state execution
    procedures set forth in “statutes and formal regulations,” but
    not those in state execution protocols. Rao Op. at 1. She also
    reads the federal protocol to contain a “carveout” “indicat[ing]
    that the government must depart from the protocol as necessary
    to . . . apply the manner of execution prescribed by state law.”
    Id. at 1, 29. The government, however, makes neither
    argument, and the protocol contains no such carveout. In my
    view, section 3596(a), best understood, requires federal
    executions to be carried out using the same procedures that
    states use to execute their own prisoners—procedures set forth
    not just in statutes and regulations, but also in protocols issued
    by state prison officials pursuant to state law. Because the
    federal protocol, on its face, takes no account of these
    procedures, it is contrary to section 3596(a), and I would vacate
    it. See 
    5 U.S.C. § 706
    (2)(A), (C) (requiring courts to “hold
    unlawful and set aside agency action . . . found to be . . . not in
    accordance with law” or “in excess of statutory jurisdiction,
    authority, or limitations, or short of statutory right”).
    Plaintiffs were sentenced to be executed “in the manner
    prescribed by the law,” 
    18 U.S.C. § 3596
    (a), of Arkansas,
    Missouri, Texas, and Indiana, respectively. All four states have
    enacted statutes that establish lethal injection as the method of
    execution and delegate to state prison officials the task of
    developing specific execution procedures. Pursuant to these
    statutes, state officials have adopted execution protocols that
    designate, among other things, the chemicals to be
    administered, dosages, procedures for vein access, and
    qualifications of execution personnel. State officials adopt such
    protocols not just to comply with state law, but also to ensure
    3
    that executions comply with the Constitution. Cf. Baze v. Rees,
    
    553 U.S. 35
    , 55–56 (2008) (plurality opinion) (rejecting Eighth
    Amendment method-of-execution challenge “in light of”
    “important safeguards” contained in state execution protocol,
    including “that members of the [intravenous] team . . . have at
    least one year of professional experience” and specific vein-
    access procedures); Raby v. Livingston, 
    600 F.3d 552
    , 560 (5th
    Cir. 2010) (rejecting Texas inmate’s Eighth Amendment claim
    because state execution protocol “mandates . . . that sufficient
    safeguards are in place to reduce the risk of pain below the level
    of constitutional significance”).
    For example, Texas’s governing statute requires
    condemned prisoners to be “executed . . . by intravenous
    injection . . . , [with] such execution procedure to be
    determined and supervised by the director of the correctional
    institutions division of the Texas Department of Criminal
    Justice.” Tex. Code Crim. Proc. Ann. art. 43.14(a). Pursuant to
    that statute, the Director “adopt[ed]” an “Execution
    Procedure,” under which “100 milliliters of solution containing
    5 grams of Pentobarbital” “shall be mixed . . . by members of
    the drug team,” which, in turn, “shall have at least one
    medically trained individual,” a term defined in the protocol.
    Texas Department of Criminal Justice, Correctional
    Institutions Division, Execution Procedure 2, 7–8 (Apr. 2019),
    Administrative Record (A.R.) 84, 89–90. The protocol further
    requires that intravenous lines be inserted by “a medically
    trained individual” who “shall take as much time as is needed”
    to do so “properly,” and who is prohibited from employing a
    “cut-down” technique, a surgical procedure that exposes the
    vein. Id. at 8, A.R. 90.
    The governing Missouri statute “authorize[s] and
    direct[s]” “the director of the department of corrections . . . to
    provide a suitable and efficient room or place . . . and the
    4
    necessary appliances” for carrying out lethal injections and
    requires “[t]he director . . . [to] select an execution team.” 
    Mo. Rev. Stat. § 546.720.1
    –2. Pursuant to that statute, the Director
    issued a protocol requiring prisoners to be executed using two
    five-gram doses of pentobarbital—quantities that “may not be
    changed without prior approval of the department director”—
    which “shall be injected into the prisoner . . . under the
    observation of medical personnel,” namely, “a physician,
    nurse, and pharmacist.” Missouri Department of Corrections,
    Preparation and Administration of Chemicals for Lethal
    Injection 1–2 (Oct. 18, 2013), A.R. 70–71.
    The other two states—Arkansas and Indiana—have
    similar statutory schemes. See 
    Ark. Code Ann. § 5-4-617
     (“The
    director [of the Department of Correction] shall develop
    logistical procedures necessary to carry out the sentence of
    death, including . . . [e]stablishing a protocol for any necessary
    mixing or reconstitution of the drugs and substances set forth
    in this section in accordance with the instructions.”); 
    Ind. Code § 35-38-6-1
     (authorizing “[t]he department of correction [to]
    adopt rules” to implement lethal-injection statute); see also
    Kelley v. Johnson, 
    496 S.W.3d 346
    , 352 (Ark. 2016)
    (discussing Arkansas’s lethal injection protocol); Department
    of Correction, Indiana State Prison Facility Directive, ISP 06-
    26: Execution of Death Sentence 16–17 (Jan. 22, 2014), Mot.
    for Prelim. Inj. Barring the Scheduled Execution of Pl. Dustin
    Lee Honken, Ex. 6, In the Matter of the Federal Bureau of
    Prisons’ Execution Protocol Cases, No. 19-mc-145 (D.D.C.
    Nov. 5, 2019).
    The “law” of each state, then, requires executions to be
    implemented according to procedures determined by state
    corrections officials, who, in turn, have set forth such
    procedures in execution protocols. In other words, “by law,”
    each state directed its prison officials to develop execution
    5
    procedures, and “by law,” those officials established such
    procedures and set them forth in execution protocols.
    Accordingly, the protocols have been “prescribed by . . . law.”
    
    18 U.S.C. § 3596
    (a). Apparently agreeing, the government
    argues that interpreting “manner” to mean more than
    “method,” as Judge Rao and I do, would require it to use the
    same drugs as the states—drugs “prescribed” in the relevant
    states’ protocols, not in their statutes. See Appellants’ Br. 29.
    Indeed, at oral argument government counsel rejected the
    notion that “the law of the State” excludes execution protocols,
    calling it “incongruous to think that Congress thought the
    degree of federal control over how to implement . . . a federal
    execution was going to depend on the happenstance of exactly
    where in its law or regulation or sub-regulatory guidance a state
    chose to write out very detailed procedures.” Oral Arg. Rec.
    39:12–32.
    Were there any doubt about this, “the natural way to draw
    the line is in light of the statutory purpose,” Rose v. Lundy, 
    455 U.S. 509
    , 517 (1982) (internal quotation marks and citation
    omitted), and here, interpreting section 3596(a) to include state
    execution protocols “best effectuates the underlying purposes
    of the statute,” Vanguard Interstate Tours, 
    735 F.2d at 597
    . As
    Judge Rao points out, section 3596(a) replicates nearly word-
    for-word the statute that governed federal executions from
    1937 to 1984. Like the FDPA, that statute required executions
    to be carried out in “the manner prescribed by the laws of the
    State within which the sentence [wa]s imposed,” or, if that state
    had no death penalty, another state designated by the
    sentencing court. Act of June 19, 1937, ch. 367, 
    50 Stat. 304
    (repealed 1984) (“1937 Act”). Central to the issue before us,
    Congress passed the 1937 Act because the states were
    undertaking serious efforts to make executions more humane.
    See H.R. Rep. 75-164 at 2 (1937) (letter from Attorney General
    Homer Cummings) (advising Congress that states “have
    6
    adopted more humane methods” of execution than hanging and
    recommending that “the Federal Government likewise . . .
    change its law in this respect”); see also Stuart Banner, The
    Death Penalty: An American History 171 (2002) (explaining
    that, as early as the 1830s, states had begun experimenting with
    execution procedures, endeavoring to “minimize the
    condemned person’s pain”). Accordingly, almost all federal
    executions pursuant to the 1937 Act were carried out by state
    officials, who, supervised by U.S. Marshals, executed federal
    prisoners in the same “manner” as they executed their own. See
    Oral Arg. Rec. 15:00–03 (government counsel agreeing that
    most executions pursuant to the 1937 Act were carried out in
    state facilities); David S. Turk, Forging the Star: The Official
    Modern History of the United States Marshals Service 23–24
    (2016) (describing how the U.S. Marshal arranged for Ethel
    and Julius Rosenberg to be executed at Sing-Sing Correctional
    Facility, then home to New York state’s death row and electric
    chair).
    By using virtually identical language in FDPA section
    3596(a), Congress signaled its intent to continue the same
    system—for federal executions to be carried out in the same
    manner as state executions. See Lorillard v. Pons, 
    434 U.S. 575
    , 580 (1978) (“Congress is presumed to be aware of an
    administrative . . . interpretation of a statute and to adopt that
    interpretation when it re-enacts a statute without change.”).
    Given this, reading section 3596(a) to exclude state execution
    protocols, which set forth the very procedures states use to
    carry out executions humanely, would run contrary not only to
    section 3596(a)’s “‘ultimate purpose[]’” of ensuring more
    humane executions, but also to “‘the means [Congress] has
    deemed appropriate . . . for the pursuit of [that] purpose[]’”—
    requiring federal prisoners to be executed in the same manner
    as states execute their own. Gresham v. Azar, 
    950 F.3d 93
    , 101
    (D.C. Cir. 2020) (quoting MCI Telecommunications Corp. v.
    7
    American Telephone & Telegraph Co., 
    512 U.S. 218
    , 231 n.4
    (1994)). And at least as recently as 2008, the states have “by all
    accounts” “fulfilled” their “role . . . in implementing their
    execution procedures . . . with an earnest desire to provide for
    a progressively more humane manner of death.” Baze, 
    553 U.S. at 51
    .
    Judge Rao argues that state execution protocols are not
    “prescribed by . . . law” within the meaning of section 3596(a)
    because they are not “formal regulations.” Rao Op. at 1. In
    support, she cites Chrysler Corp. v. Brown, 
    441 U.S. 281
    (1979), in which the Supreme Court considered a provision of
    the Trade Secrets Act that protected confidential information
    by prohibiting its disclosure unless “‘authorized by law,’” 
    id. at 294
     (quoting 
    18 U.S.C. § 1905
    ). The Court held that a
    regulation issued pursuant to an agency’s “housekeeping”
    statute and without notice-and-comment procedures did not
    qualify as “law” under the Act. 
    Id.
     at 309–16. From this, Judge
    Rao concludes that the word “law” in FDPA section 3596(a) is
    limited to regulations issued pursuant to notice-and-comment
    procedures. See Rao Op. at 7, 28 n.13.
    By my count, the phrase “authorized by law” and its twin
    sisters—“prescribed by law” and “prescribed by the law”—
    appear 1,120 times in the United States Code, and the Supreme
    Court has repeatedly made clear that, even within the same
    statute, “the presumption of consistent usage ‘readily yields’ to
    context.” Utility Air Regulatory Group v. EPA, 
    573 U.S. 302
    ,
    320 (2014) (quoting Environmental Defense v. Duke Energy
    Corp., 
    549 U.S. 561
    , 574 (2007)). In Chrysler, moreover, it was
    only after closely examining “evidence of legislative intent,”
    including statutory text and legislative history, that the Court
    limited “law” in the Trade Secrets Act to notice-and-comment
    regulations. 
    441 U.S. at 312
    . In other words, context matters,
    and here context requires a different result. Limiting “the
    8
    manner prescribed by the law of the State” to execution
    procedures contained in statutes and in regulations issued
    pursuant to notice and comment, and thereby excluding those
    contained in state execution protocols, would defeat section
    3596(a)’s purpose—to make federal executions more humane
    by ensuring that federal prisoners are executed in the same
    manner as states execute their own.
    Judge Rao also argues that the Attorney General need not
    follow state execution protocols because they “do not appear to
    have the binding force of law,” “leav[ing] the federal
    government free to specify” its own procedures. Rao Op. at 2,
    28 n.15. But whether state execution protocols are binding
    under state law has nothing to do with whether the Attorney
    General has authority under federal law to issue a uniform
    execution protocol. And as explained above, section 3596(a)
    shifts authority for determining how to “implement” death
    sentences to the states, leaving no comparable authority for the
    Attorney General. Indeed, apart from the Attorney General’s
    authority to establish procedures unrelated to “effectuat[ing]
    the death,” see infra at 12, the statute assigns the Attorney
    General just three narrow tasks: keeping custody of persons
    sentenced to death until they exhaust their appeals, 
    18 U.S.C. § 3596
    (a); releasing prisoners into Marshal custody for
    implementation of their death sentences, id.; and approving the
    amount Marshals may pay for the use of state facilities and
    personnel, 
    id.
     § 3597(a).
    Of course, the federal protocol’s failure to incorporate
    state execution procedures would pose no problem if, as Judge
    Rao believes, it contained a “carveout,” “indicat[ing] that the
    government must depart from the protocol as necessary to . . .
    9
    apply the manner of execution prescribed by state law.” Rao
    Op. at 1, 29. But it does not. In relevant part, the protocol states:
    The procedures utilized by the [Bureau of
    Prisons (BOP)] to implement federal death
    sentences shall be as follows unless modified
    at the discretion of the Director or his/her
    designee, as necessary to (1) comply with
    specific judicial orders; (2) based on the
    recommendation of on-site medical
    personnel utilizing their clinical judgment;
    or (3) as may be required by other
    circumstances.
    Department of Justice, Addendum to BOP Execution Protocol,
    Federal Death Sentence Implementation Procedures 1 (July 25,
    2019) (emphasis added).
    Far from requiring Marshals to follow state law, this
    provision mentions neither state law nor section 3596(a), and it
    leaves the decision to “modif[y]” protocol procedures to “the
    discretion” of the BOP Director, id. Moreover, only the third
    justification for departing from the protocol—“other
    circumstances,” id.—could possibly encompass inconsistent
    state law. But the government—which, after all, wrote the
    protocol—does not so argue. At most, the government suggests
    that it could exercise its residual discretion in accordance with
    state law, noting that “nothing in the federal protocol expressly
    precludes” “offer[ing] . . . a sedative” or having a physician
    present. Appellants’ Br. 33 (referring to the two differences
    between the federal protocol and the relevant state protocols
    identified by the district court).
    Where, as here, agency action is challenged under the
    Administrative Procedure Act, we can uphold the action only
    10
    on “[t]he grounds . . . upon which the record discloses that [it]
    was based.” SEC v. Chenery Corp., 
    318 U.S. 80
    , 87 (1943).
    Throughout this litigation, the government has insisted that
    requiring it to comply with state law would be “perverse[],”
    Appellants’ Br. 19, and would “hamstring” implementation of
    the federal death penalty, Reply Br. 13. We have no authority
    to rewrite the protocol to ensure it complies with the FDPA.
    “[A]gency policy is to be made, in the first instance, by the
    agency itself . . . . Courts ordinarily do not attempt . . . to
    fashion a valid regulation from the remnants of the old rule.”
    Harmon v. Thornburgh, 
    878 F.2d 484
    , 494 (D.C. Cir. 1989).
    The problem with Judge Rao’s interpretation of the protocol,
    then, is not just that it represents an “independent assessment”
    of the protocol’s meaning, Rao Op. at 30, but more
    fundamentally that “it sustains a rule which the agency has
    never adopted at all,” Harmon, 
    878 F.2d at
    495 n.20.
    I end with a few observations about the government’s
    defense of the protocol.
    First, had Congress intended to authorize the Attorney
    General to adopt a uniform execution protocol, “it knew
    exactly how to do so.” SAS Institute, Inc. v. Iancu, 
    138 S. Ct. 1348
    , 1355 (2018). The year before Congress enacted the
    FDPA, then-Attorney General William Barr issued a regulation
    setting lethal injection as the uniform federal method of
    execution and authorizing the BOP Director to determine
    which chemicals to use. See Department of Justice,
    Implementation of Death Sentences in Federal Cases, 
    58 Fed. Reg. 4898
    , 4901–02 (Jan. 19, 1993) (codified at 
    28 C.F.R. § 26.3
    ) (1993 Regulation). This regulation was a gap-filler:
    several years earlier, Congress had repealed the 1937 Act,
    leaving unclear how federal executions would be carried out.
    11
    While Congress was considering the bill that would become the
    FDPA, General Barr’s successor, Attorney General Janet Reno,
    warned that section 3596(a)’s “proposed procedures
    contemplate a return to an earlier system”—i.e., the 1937
    Act—“in which the Federal Government does not directly
    carry out executions, but makes arrangements with states to
    carry out capital sentences in Federal cases.” H.R. Rep. No.
    104–23, at 22 (1995) (quoting Letter of Attorney General Janet
    Reno to Honorable Joseph R. Biden, Jr., Detailed Comments at
    3–4 (June 13, 1994)). She therefore recommended that
    Congress amend the bill “to perpetuate the current approach”—
    i.e., the 1993 Regulation—“under which the execution of
    capital sentences in Federal cases is carried out by Federal
    officials pursuant to uniform regulations issued by the Attorney
    General.” 
    Id.
     Despite this recommendation, “Congress didn’t
    choose to pursue that known and readily available approach
    here. And its choice”—to require executions to be carried out
    according to state, not federal, law—“must be given effect
    rather than disregarded.” SAS Institute, 
    138 S. Ct. at 1356
    .
    Second, the government argues that requiring it to comply
    with state law would “preclud[e]” it “from selecting more
    humane lethal-injection protocols than those used by the
    states.” Appellants’ Br. 29. As explained above, however,
    section 3596(a), like the 1937 Act, relies on the states, not the
    Attorney General, to ensure that federal executions are
    humane. Perhaps circumstances have changed and authorizing
    the Attorney General to select lethal substances, dosages, and
    injection procedures would lead to more humane executions.
    That, however, “is a decision for Congress and the President to
    make if they wish by enacting new legislation.” Loving v. IRS,
    
    742 F.3d 1013
    , 1022 (D.C. Cir. 2014); see also Rao Op. at 24.
    They have ready templates in the nine bills Congress has
    considered and rejected in the years since the FDPA’s
    enactment, every one of which would have permitted federal
    12
    executions to be carried out “pursuant to regulations prescribed
    by the Attorney General.” H.R. 2359, 104th Cong. § 1 (1995);
    see also H.R. 851, 110th Cong. § 6 (2007); H.R. 3156, 110th
    Cong. § 126 (2007); S. 1860, 110th Cong. § 126 (2007); H.R.
    5040, 109th Cong. § 6 (2006); S. 899, 106th Cong. § 6504
    (1999); H.R. 4651, 105th Cong. § 501 (1998); S. 3, 105th
    Cong. § 603 (1997); H.R. 1087, 105th Cong. § 1 (1997).
    Finally, the government argues that requiring it to follow
    “every nuance” of state protocols “could impose significant
    barriers to administering” the federal death penalty.
    Appellants’ Br. 27. Plaintiffs, however, do not contend that the
    government must follow “every nuance.” Quite to the contrary,
    they argue, and I agree, that section 3596(a) requires the federal
    government to follow only “implementation” procedures, 
    18 U.S.C. § 3596
    (a), which plaintiffs define as those procedures
    that “effectuat[e] the death,” Oral Arg. Rec. 1:01:06, including
    choice of lethal substances, dosages, vein-access procedures,
    and medical-personnel requirements, see 
    id.
     1:01:58–1:05:25.
    To be sure, plaintiffs’ interpretation could present courts with
    line-drawing challenges: is, for example, color-coding syringes
    part of effectuating an execution? But here we face no such
    challenges given that the federal protocol fails to account for
    state procedures that are obviously integral to
    “implement[ing]” a death sentence, 
    18 U.S.C. § 3596
    (a).
    In any event, if crafting a federal protocol consistent with
    the FDPA proves too difficult, then the Attorney General may,
    pursuant to section 3596(a), arrange for plaintiffs to be
    executed by the relevant states—just as most federal prisoners
    have been since 1937. See Oral Arg. Rec. 1:38:13–34
    (plaintiffs’ counsel acknowledging as much). The government
    fears that states could “block implementation of a federal death
    sentence,” Appellants’ Br. 28, but at oral argument government
    counsel assured us that the government has no evidence of state
    13
    recalcitrance in this case, see Oral Arg. Rec. 18:50–55
    (responding “no” to the question whether there “is any
    evidence of” “obstructionism” “in this case”). And if such
    problems do come to pass—that is, if section 3596(a)’s
    incorporation of state procedures creates obstacles for federal
    executions—then Congress will have all the more reason to
    revise the statute. Until it does, this court must enforce section
    3596(a) as written. “[I]t is never our job to rewrite . . . statutory
    text under the banner of speculation about what Congress
    might have done had it faced a question that, on everyone’s
    account, it never faced.” Henson v. Santander Consumer USA
    Inc., 
    137 S. Ct. 1718
    , 1725 (2017).
