    Before: SRINIVASAN, Chief Judge, MILLETT and PILLARD,
    Circuit Judges.
    Opinion for the Court filed by Circuit Judge PILLARD.
    PILLARD, Circuit Judge: When issues arise during the
    term of a collective bargaining agreement that are not covered
    by the agreement, federal employees may seek to bargain with
    their agency employers over how such issues should be
    handled. For its part, an agency may try to head off such
    midterm bargaining by securing during term bargaining a
    clause in the parties’ collective bargaining agreement that
    limits or forecloses midterm bargaining. Such a clause is
    commonly referred to as a zipper clause—a clause that treats
    the term agreement as having zipped up, or closed off, potential
    midterm bargaining. Unions, valuing the opportunity to
    negotiate midterm on unforeseen matters not already covered
    by the existing agreement, such as the effect of a pandemic on
    the workplace, generally oppose zipper clauses.
    It is not disputed that parties may negotiate over and agree
    to a zipper clause. But what happens if an agency proposes a
    zipper clause, and the union disagrees on whether or to what
    extent to include it in the collective bargaining agreement? The
    answer largely depends on whether zipper clauses are a
    “mandatory” or “permissive” subject of bargaining. Federal
    labor law treats some subjects of collective bargaining as
    mandatory, meaning that when parties bargain to impasse over
    proposals on those subjects, a dissatisfied party may seek
    resolution from the Federal Service Impasses Panel. And Panel
    resolution may include imposition of the clause in the
    agreement over the other party’s objection. In contrast,
    subjects that are permissive for one or both parties are those on
    which a party may choose to, but need not, bargain. A party
    may decline to negotiate on proposals on permissive subjects,
    3
    and its counterparty may not take disputes over such proposals
    to the impasses panel for potential insertion into the agreement.
    The unions here challenge a Policy Statement of the
    Federal Labor Relations Authority that announced for the first
    time that zipper clauses are mandatory bargaining subjects.
    U.S. Off. of Pers. Mgmt. (Petitioner) (Policy Statement), 
    71 F.L.R.A. 977
    , 977 (Sept. 30, 2020). In other words, the
    Authority determined that, if an agency and a union intractably
    disagree over a zipper clause proposal, the agency may bring
    the proposal to the impasses panel—which has the authority to
    put it (or a different clause reflecting what it determines to be
    a better resolution) into the parties’ term agreement. FLRA
    policy statements are unusual: Before producing a spate of
    them in 2020, including the one challenged here, the Authority
    had not issued any Policy Statement in over thirty-five years.
    Three labor unions challenge this one as arbitrary and
    capricious.
    We grant the petitions for review and vacate the Policy
    Statement. Importantly for our analysis, the Authority chose to
    structure its consideration of the zipper clause question in two
    steps, casting its answer at step one as also determinative of
    step two. The Authority first held that the Federal Service
    Labor-Management Relations Statute (Statute) does not entitle
    employees to demand midterm bargaining even when the
    parties’ agreement is silent on the matter. Policy Statement, 71
    F.L.R.A. at 979. The Authority then relied on that holding as
    “necessary” to its conclusion that proposed contractual zipper
    clauses expressly foreclosing midterm bargaining are
    mandatory bargaining subjects. Id. at 979 n.35. The first
    holding was arbitrary and capricious. The Authority’s errors
    include miscasting Supreme Court precedent, relying on
    conclusory assertions, and mischaracterizing its dramatic shift
    of the bargaining baseline as allowing “the parties to resolve”
    4
    the issue. Id. at 979. And, because the Authority avowedly
    rested its second holding on its first, we must vacate the zipper
    clause holding as well. In view of these conclusions, we need
    not rule on the unions’ threshold objection that the Authority
    ignored its own criteria for issuance of general statements of
    policy. See 
    5 C.F.R. § 2427.5
    .
    I. BACKGROUND
    In July 2019, the Office of Personnel Management (OPM)
    petitioned the Authority for a policy statement on the question
    whether zipper clauses are mandatory or permissive bargaining
    subjects. See 
    5 U.S.C. § 7105
    (a)(1) (statutory basis for FLRA
    policy statements); 
    5 C.F.R. §§ 2427.1
    -.5 (governing
    regulations). The Authority solicited comments on that
    question, and ten commenters timely responded.
    Some commenters supportive of the proposed policy
    thought that zipper clauses must be mandatory because “all
    conditions of employment are presumed to be mandatory
    subjects of bargaining” unless the Statute “explicitly or by
    unambiguous implication” defines them as permissive, which
    they argued it does not. See, e.g., U.S. Dep’t of Agric.,
    Comment Letter on Proposed General Statement of Policy
    (Apr. 29, 2020) (quoting Nat’l Treasury Emps. Union v. FLRA
    (NTEU 2005), 
    399 F.3d 334
    , 340 (D.C. Cir. 2005)), J.A. 67-68.
    Commenters reasoned that zipper clauses should be viewed as
    mandatory based on the Authority’s mandatory
    characterization of reopener clauses, which expressly allow
    midterm bargaining that would otherwise be foreclosed as to
    subjects already “covered by” a term agreement. See Nat’l
    Treasury Emps. Union & U.S. Customs Serv., 
    64 F.L.R.A. 156
    ,
    157-58 (2009). Agencies also commented that restricting
    midterm bargaining would promote efficiency by encouraging
    5
    parties to predict their needs during initial, term bargaining so
    prevent “piecemeal” negotiation. 1
    Opponents of the proposed policy argued that the Statute
    establishes a unilateral statutory right to bargain midterm,
    equal to the right to bargain at term. Noting that the Authority
    recognizes midterm bargaining over the impact and
    implementation of certain management-initiated changes as a
    unilateral right subject to waiver only on a permissive basis,
    commenters applied the same reasoning to midterm bargaining
    on other subjects. Comments distinguished zipper clauses
    from reopeners, pointing out that reopeners address already-
    bargained issues whereas zippers “alter[] the scope of the duty
    to bargain mid-term with respect to virtually all contract terms
    . . . not resolved by the agreement”—including those never
    negotiated or anticipated. 2 Empowering the impasses panel to
    impose zipper clauses and long duration provisions,
    commenters predicted, “would adversely affect and prolong
    term bargaining” because, “[w]ithout the ability to bargain
    midterm, a union would feel compelled to bargain over and
    address every possible scenario, no matter how unlikely, that
    might come up during the term of the agreement.” Nat’l
    Treasury Emps. Union, Comment Letter on Proposed General
    Statement of Policy (Apr. 30, 2020), J.A. 47.

    6
    We have had few occasions to address the distinction
    between mandatory and permissive subjects of bargaining. In
    American Federation of Government Employees v. FLRA
    (AFGE 1983), 
    712 F.2d 640
     (D.C. Cir. 1983), we held that
    matters relating to conditions of employment are
    presumptively mandatory bargaining subjects unless the
    Statute “explicitly or by unambiguous implication” provides a
    party with a “unilateral right[]” regarding the matter under
    consideration. AFGE 1983, 
    712 F.2d at
    646 & n.27 (formatting
    modified). If the Statute clearly confers a right on a party, in
    other words, the party may refuse to bargain over proposals on
    that matter. Agencies, for instance, need not bargain over their
    right “to determine the mission, budget, organization, number
    of employees, and internal security practices of the agency.” 
    5 U.S.C. § 7106
    (a)(1). And employees need not bargain over
    their right “to engage in collective bargaining with respect to
    conditions of employment.” 
    5 U.S.C. § 7102
    . But a party must
    bargain in good faith over any lawful proposal that does not
    trench on its unilateral rights.
    We reaffirmed and elaborated that standard in National
    Treasury Employees Union v. FLRA (NTEU 2005), 
    399 F.3d 334
     (D.C. Cir. 2005). We explained that not all rights provided
    by the Statute are necessarily unilateral rights and so
    permissive subjects of bargaining: Only rights which the
    Statute “explicitly or by unambiguous implication vests in a
    party” rise to the level of unilateral rights over which a party
    may but need not negotiate. NTEU 2005, 
    399 F.3d at 340
    (quoting AFGE 1983, 
    712 F.2d at
    646 n.27).
    As OPM recognized in its request for the Policy Statement,
    whether zipper clauses are mandatory or permissive bargaining
    subjects was an open question. No court had squarely decided
    whether unions have a unilateral right to bargain midterm, nor
    had the Authority. The Authority expressly declined to decide
    7
    the point in U.S. Department of the Interior, Washington, D.C.
    (Interior), 
    56 F.L.R.A. 45
     (2000), on remand from the Supreme
    Court.
    The Supreme Court had held in National Federation of
    Federal Employees, Local 1309 v. Interior (Local 1309), 
    526 U.S. 86
     (1999), that the Statute’s text is ambiguous as to
    whether it confers a general right to midterm as well as term
    bargaining. Local 1309, 
    526 U.S. at 92
    . The key provision
    simply requires that parties “meet and negotiate in good faith
    for the purposes of arriving at a collective bargaining
    agreement.” 
    Id. at 88
     (quoting 
    5 U.S.C. § 7114
    (a)(4)). As the
    Court noted, “[o]ne can easily read ‘arriving at a collective
    bargaining agreement’ as including an agreement reached at
    the conclusion of midterm bargaining” just as it includes one
    resulting from term bargaining. Id. at 93 (second emphasis
    added). The Court acknowledged agencies’ concerns that
    midterm bargaining could incentivize piecemeal negotiation,
    but also recognized policy reasons that the Statute might
    require midterm bargaining: “Without midterm bargaining,”
    the Court wondered, “will it prove possible to find a collective
    solution to a workplace problem, say, a health or safety hazard,
    that first appeared midterm?” Id. at 94. Indeed, the Court
    reasoned, “[t]he Statute’s emphasis upon collective bargaining
    as ‘contribut[ing] to the effective conduct of public business’
    suggests that it would favor joint, not unilateral, solutions to
    such midterm problems.” Id. (second alteration in original)
    (quoting 
    5 U.S.C. § 7101
    (a)(1)(B)). The Court accordingly
    remanded for the Authority, informed by its “expertise in its
    field of labor relations,” to decide whether the Statute requires
    midterm bargaining. Id. at 99 (quoting Bureau of Alcohol,
    Tobacco & Firearms v. FLRA, 
    464 U.S. 89
    , 97 (1983)).
    The Authority took up that question in Interior and held
    that “under the Statute, agencies are obligated to bargain during
    8
    the term of a collective bargaining agreement on negotiable
    union proposals concerning matters that are not ‘contained in
    or covered by’ the term agreement, unless the union has waived
    its right.” Interior, 56 F.L.R.A. at 54. Quoting Congress’s
    statutory findings supportive of public-sector collective
    bargaining, the Authority underscored that nothing in the
    Statute suggests those findings are any less applicable to
    midterm than term bargaining. Id. at 51 (quoting 
    5 U.S.C. § 7101
    (a)(1)). The Authority’s own judgment, informed by its
    experience, was that midterm bargaining leads to “more
    focused negotiations,” neither prompting kitchen-sink term
    bargaining over issues that might never arise, nor delaying
    resolution of important concerns that arise midterm until term
    negotiations recommence. Id. at 52. The Authority rejected as
    “unsupported and speculative” arguments that union-initiated
    midterm bargaining was harmful to federal sector labor
    relations. Id. at 54. In its experience, midterm bargaining was
    appropriately limited by the doctrine barring renegotiation of
    matters covered by the term agreement, gave rise to few
    disputed cases, and had not led to piecemeal or “continuous”
    bargaining as critics feared. Id. at 53.
    But Interior decided only the default rule that parties have
    a “statutory right” to bargain midterm if the contract is
    otherwise silent. The Authority disclaimed any view on
    whether proposals for contractual zipper clauses are mandatory
    or permissive bargaining subjects. See Interior, 56 F.L.R.A. at
    54 (“[W]e will not consider” here the question “whether
    ‘zipper clauses’ are a mandatory subject of negotiation.”). In
    deciding that the Statute requires midterm bargaining, then,
    Interior left open whether it does so “by unambiguous
    implication” so confers a “unilateral right” of the sort AFGE
    1983 and NTEU 2005 described. That state of affairs prevailed
    for two decades.
    9
    The Authority in November 2019 rejected a request to
    revisit Interior, describing the case as its “seminal” precedent
    recognizing the statutory right to midterm bargaining. See
    OPM, 
    71 F.L.R.A. 423
    , 423 (2019). But just ten months later,
    in the Policy Statement before us, the Authority reversed
    course. Before addressing the question expressly left open by
    Interior, the Authority circled back to repudiate the core
    holding of Interior that it had reaffirmed just months earlier.
    Deeming reconsideration of that issue “necessary” to its
    decision of the question OPM presented—whether zipper
    clauses are mandatory or permissive—the Authority revisited
    Interior’s holding that the Statute requires midterm bargaining
    at all, even as a default rule. See Policy Statement, 71 F.L.R.A.
    at 979 n.35.
    In a paragraph, the Authority jettisoned Interior. Contrary
    to its reasoning in Interior, the Authority’s Policy Statement
    deemed it “more appropriate” to conclude that the Statute does
    not require midterm bargaining. See Policy Statement, 71
    F.L.R.A. at 979. The Authority declared that the Statute
    “clearly established” an obligation to bargain at term, but it saw
    “indeterminacy in the Statute’s text” as to whether it requires
    midterm bargaining. Id. The entirety of its analysis of the
    distinction it drew is terse:
    As previously mentioned, the Supreme Court [in
    Local 1309] held that the Statute does not clearly
    require or prohibit midterm bargaining. In its decision
    on remand from the Supreme Court, the Authority
    decided that the Statute requires midterm bargaining.
    However, the Authority’s first consideration to
    support that conclusion is flawed. In particular, the
    Authority found that the Statute does not distinguish
    between obligations for midterm and term bargaining.
    But in one important respect, those obligations are
    10
    distinguishable: The parties’ mutual obligation to
    bargain in term negotiations is clearly established in
    the Statute, whereas a mutual obligation to bargain
    midterm is not. Indeed, that indeterminacy in the
    Statute’s text was the driving force behind the
    Supreme Court’s ruling.            Although the Court
    recognized that the Authority could resolve that
    ambiguity, and the Authority did so, we find it more
    appropriate to recognize that the Statute neither
    requires nor prohibits midterm bargaining. Instead,
    the Statute leaves midterm-bargaining obligations to
    the parties to resolve as part of their term negotiations.
    Id. (footnotes omitted).
    Having erased Interior by holding that the Statute simply
    does not obligate agencies to bargain midterm, the Authority
    then addressed the question OPM had posed: whether zipper
    clauses are mandatory or permissive bargaining subjects.
    Basing its conclusion on its reversal of Interior, the Authority
    held that zipper clauses are mandatory bargaining subjects.
    Immediately after the above-quoted paragraph regarding
    Interior, the Authority dispatched the zipper clause issue as
    follows:
    Thus, we now hold that proposals that concern
    midterm-bargaining   obligations—whether they
    resemble reopener or zipper clauses, or take some
    other form—are mandatory subjects of bargaining
    under the Statute.
    That treatment is consistent with the Authority’s
    previous recognition that matters relating to the
    parties’ midterm-bargaining relationship plainly
    relate to conditions of employment. Further, the
    Statute presumes that all matters relating to conditions
    11
    of employment are mandatory subjects of bargaining
    unless the text explicitly or by unambiguous
    implication vests in a party an unqualified, or
    “unilateral,” right. As explained above, the Statute
    does not, on its own, explicitly or by unambiguous
    implication vest either party with a unilateral right to
    engage in midterm bargaining.         In other words,
    because neither party would be required to waive a
    statutory right, any proposal concerning midterm
    bargaining would come within the default rule that all
    matters relating to conditions of employment are
    mandatory subjects of bargaining.
    Policy Statement, 71 F.L.R.A. at 979-80 (footnotes omitted).
    The core of the Authority’s reasoning is that, “[a]s
    explained above” in the prior paragraph regarding Interior, the
    Statute does not require midterm bargaining at all, even as a
    default matter, so necessarily fails to establish any unilateral
    right to midterm bargaining that would make it permissive, not
    mandatory, for unions to negotiate whether to retain that right
    to bargain. Id. at 980. The Authority held that the Statute
    consequently treats zipper clauses as mandatory bargaining
    subjects that, upon impasse, may be imposed on unions against
    their will by action of the impasses panel. In a footnote, the
    Authority added that it was “necessary” to decide whether the
    Statute requires midterm bargaining “in order to properly
    evaluate” the zipper clause question. Id. at 979 n.35. The
    Authority also asserted that other statutory language, which
    allows parties to determine appropriate techniques to aid their
    negotiations, offered “further support” for its position. Id. at
    980.
    Three federal employee labor unions timely petitioned for
    review, and we consolidated those cases. The unions contend
    12
    that the Authority violated its regulations providing criteria for
    issuance of Policy Statements, abrogated its precedent without
    reasoned explanation and in contravention of the Statute’s text
    and purpose, and relied on unreasoned bases for concluding
    that zipper clauses are mandatory subjects of bargaining. We
    have jurisdiction, 
    5 U.S.C. § 7123
    (a), and the unions have
    standing, see AFGE v. FLRA, 
    750 F.2d 143
    , 144-45 (D.C. Cir.
    1984).
    II. ANALYSIS
    We evaluate the Authority’s Policy Statement under the
    arbitrary and capricious standard of review. 
    5 U.S.C. § 7123
    (c); see Motor Vehicle Mfrs. Ass’n v. State Farm Mut.
    Auto. Ins. Co., 
    463 U.S. 29
    , 34 (1983). Under that standard,
    “we must ensure that the Authority examined the relevant data
    and articulated a satisfactory explanation for its action
    including a rational connection between the facts found and the
    choice made.” AFGE v. FLRA (AFGE 2020), 
    961 F.3d 452
    ,
    456 (D.C. Cir. 2020) (formatting modified). Put another way,
    the Authority must show that its decision “was the product of
    reasoned decisionmaking.” State Farm, 
    463 U.S. at 52
    ; accord
    AFGE 2020, 961 F.3d at 456-57 (quoting Allentown Mack
    Sales & Serv., Inc. v. NLRB, 
    522 U.S. 359
    , 374 (1998)).
    We “must judge the propriety of [an agency’s] action
    solely by the grounds invoked by the agency.” SEC v. Chenery
    Corp. (Chenery II), 
    332 U.S. 194
    , 196 (1947). “[C]ourts may
    not accept appellate counsel’s post hoc rationalizations for
    agency action.” State Farm, 
    463 U.S. at
    50 (citing Burlington
    Truck Lines, Inc. v. United States, 
    371 U.S. 156
    , 168 (1962)).
    We may limit invalidation to defective portions of an agency’s
    action and leave others standing when “they operate entirely
    independently of one another,” Davis Cnty. Solid Waste Mgmt.
    v. EPA, 
    108 F.3d 1454
    , 1459 (D.C. Cir. 1997), but will
    13
    invalidate the action as a whole if we are not “sure” the
    provisions are “wholly independent,” Am. Petroleum Inst. v.
    EPA, 
    862 F.3d 50
    , 71 (D.C. Cir. 2017).
    We begin where the Authority did, with its holding that the
    Statute does not require midterm bargaining. We vacate that
    holding as arbitrary and capricious. We then consider the
    Agency’s ultimate holding that zipper clauses are mandatory
    bargaining subjects. Because the Authority treated its first,
    invalid holding as the “necessary” predicate to its second, we
    must vacate the latter as well.
    A.   The Authority’s First Holding Was Arbitrary and
    Capricious.
    The Authority failed to offer a reasoned explanation for its
    decision that the Statute does not require midterm bargaining.
    The Policy Statement simply deemed it “more appropriate” to
    read the Statute to not require midterm bargaining. Policy
    Statement, 71 F.L.R.A. at 979. But it offered no non-arbitrary
    reason why.
    The only explanation the Authority offered was what it
    saw as a negative implication of the statutory text: The Statute
    “clearly      established”    term     bargaining      but     was
    “indetermina[te]” as to midterm bargaining, it reasoned,
    implying the exclusion of the latter. Id. But the statutory text
    does not separately define term and midterm bargaining. The
    text the Authority leans on as showing the “one important
    respect” in which the Statute differentiates the two bargaining
    stages, id., in fact makes no distinction at all. It says only that
    the parties must “meet and negotiate in good faith for the
    purposes of arriving at a collective bargaining agreement”—
    whether in term or midterm negotiations.                
    5 U.S.C. § 7114
    (a)(4).
    14
    Indeed, the Supreme Court in Local 1309 held that the very
    phrase on which the Authority here relies does not differentiate
    the two bargaining stages, so that text cannot alone impart the
    meaning the Policy Statement ascribes to it. The Court stressed
    that the operative provision simply refers to collective
    bargaining, and that “[o]ne can easily read ‘arriving at a
    collective bargaining agreement’ as including an agreement
    reached at the conclusion of midterm bargaining.” 
    526 U.S. at 93
     (quoting 
    5 U.S.C. § 7114
    (a)(4)); see also Policy Statement,
    71 F.L.R.A. at 983 (Member DuBester, dissenting) (observing
    that “Local 1309 rejected this very premise” that the Policy
    Statement relies on). In fact, as discussed above, the Court
    suggested that the Statute’s text, structure, history, and
    objectives taken together might imply a duty to bargain
    midterm as well as at term, see 
    526 U.S. at
    94—perhaps even
    by unambiguous implication, see Interior, 56 F.L.R.A. at 54
    (leaving the point open). As manifest by the Court’s remand,
    the textual ambiguity of the identified phrase does not itself
    mean that midterm bargaining is not required.
    The Authority’s contrary view cannot stand. Its parsing of
    the same few words that the Court considered in Local 1309
    was the only reason the Authority gave for the first analytic
    step of its Policy Statement. In the absence of any other
    support, that first conclusion is arbitrary and capricious.
    That flaw alone requires vacatur. But the Authority’s
    holding was unreasoned in three further ways.
    First, the Authority rested its policy decision on a basic
    mischaracterization of the Supreme Court’s holding in Local
    1309 that wrongly equated not expressly requiring midterm
    bargaining with prohibiting it. The Policy Statement declares
    that “the Supreme Court held that the Statute does not clearly
    require or prohibit midterm bargaining.” Policy Statement, 71
    15
    F.L.R.A. at 979. But the Supreme Court rejected the Fourth
    Circuit’s view that the Statute prohibits midterm bargaining.
    See Local 1309, 
    526 U.S. at 91-92
    . The only question on
    remand to the Authority following the Court’s Local 1309
    decision was whether the Statute recognizes a right to midterm
    bargaining or instead simply does not address it. See 
    id. at 88
    .
    In miscasting Local 1309 as leaving open whether the Statute
    “requires []or prohibits” midterm bargaining, 71 F.L.R.A. at
    979, the Authority incorrectly suggested its decision struck a
    middle position on the issue.
    Second, the Authority based its holding on an unsupported
    premise that its Policy Statement increased choice among the
    parties. It reasoned that “the Statute leaves midterm-
    bargaining obligations to the parties to resolve.” Policy
    Statement, 71 F.L.R.A. at 979. But reversing Interior affected
    the default rule, which applies if the parties have not otherwise
    decided whether and how they will bargain midterm. The
    Authority did not explain how altering that default to empower
    the impasses panel to intervene and forbid or limit midterm
    bargaining increases party choice.
    Third, even as it acted without advance notice or
    justification to abrogate its decades-old precedent in Interior,
    the Authority in the same breath described itself as taking no
    position on the issue Interior resolved. The Policy Statement
    commented that, following Local 1309, the Authority “could
    resolve” the textual ambiguity and “did so” in Interior, but that
    it now deemed it “more appropriate” to leave that question “to
    the parties.” 71 F.L.R.A. at 979. But it did nothing of the sort.
    In fact, as discussed above, it flipped the baseline that the
    Authority, pursuant to the Supreme Court’s remand, had set in
    Interior to hold instead that the Statute does not require
    midterm bargaining. Under the guise of neutrally declining to
    exercise the policy authority it wielded, the Authority answered
    16
    the precise question that it simultaneously said it “could” but
    did not resolve. See id.
    The Authority also gave no hint in its public notice that it
    viewed the zipper clause question as opening the door to
    reconsidering its longstanding holding in Interior. It thus
    issued its Policy Statement without the benefit of public
    comment on Interior’s continued vitality.           See Policy
    Statement, 71 F.L.R.A. at 984 & n.34 (Member DuBester,
    dissenting) (describing how commenters assumed Interior’s
    “well-established principle” was not up for reconsideration).
    But because we hold that the Authority’s reasoning was
    deficient, we need not reach whether the rule might be
    procedurally defective on that ground.
    The drive-by procedure and conclusory reasoning that
    produced the challenged Policy Statement is little match for the
    full process and detailed analysis that supported the Authority’s
    determination in Interior. There, the Authority had deployed
    subject matter expertise to analyze the Statute and assess how
    best to structure the bargaining relationship. Here, the
    Authority did nothing of the sort. It dispensed with Interior in
    one paragraph of flawed textual analysis, devoid of any
    reasoned application of its labor relations expertise. Because
    the Policy Statement does not pass muster under State Farm,
    we need not reach the unions’ contention that the Authority’s
    change from its previously established position imposed any
    distinct burden of justification, see Pet’rs’ Br. at 35-38,
    particularly whether the Authority implicitly contravened
    factual findings from Interior or unsettled strong reliance
    interests, see FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515-16 (2009).
    The Authority’s holding on the first step by which it
    structured its decision thus fails as unreasoned, so we vacate it.
    17
    B. The Authority’s Second Holding, Which It Expressly
    Rested on the First, Was Also Arbitrary and
    Capricious.
    The Authority next held that zipper clauses are mandatory
    bargaining subjects. Because the Authority rested this holding
    critically on the first, we must vacate it as well.
    The Authority expressly framed its second, zipper-clause
    holding as dependent on and flowing from its reconsideration
    of Interior. The Authority found it “necessary” to reach its first
    holding in order to “properly evaluate” the zipper clause
    question. Policy Statement, 71 F.L.R.A. at 979 n.35. Then,
    after stating what counts as a unilateral right, the Authority
    made its second holding by cross reference: “As explained
    above,” it wrote, zipper clauses must be mandatory bargaining
    subjects. Id. at 980. The Authority offered no other,
    independent rationale for its zipper clause holding.
    Under the Authority’s own decisional architecture, then,
    its second conclusion rests on its first. Bound as we are by the
    Authority’s actual justification, see Chenery II, 
    332 U.S. at 196
    , we hold that the collapse of the first step brings the second
    down with it. See also Am. Petroleum Inst., 862 F.3d at 71;
    Davis, 
    108 F.3d at 1459
    .
    In a rationale offered as “further support” for its zipper
    clause holding—not as an alternative basis that could bear the
    holding’s full weight absent the Authority’s first holding—the
    Authority pointed to section 7114(a)(4). Nothing about that
    provision helps to distinguish mandatory bargaining subjects
    from permissive ones. The Statute there says that parties “may
    determine appropriate techniques . . . to assist in any
    negotiation.” 
    5 U.S.C. § 7114
    (a)(4). The Authority reasoned
    that zipper clauses could constitute one such technique because
    they clarify the scope and timing of negotiations. Policy
    18
    Statement, 71 F.L.R.A. at 980. That reasoning is a non
    sequitur. The relevant question is whether the Statute
    explicitly or by unambiguous implication gives either party a
    right. If it does, that right is a unilateral right—even if doing
    away with it might simplify negotiations. In any event, the
    Authority did not present this “further support” for its Policy
    Statement as an alternative basis that could bear the full weight
    of its zipper-clause decision absent its first holding, so we
    cannot now view it that way. See Chenery II, 
    332 U.S. at 196
    .
