  •      Recess Appointments Amid Pro Forma Senate Sessions
    A twenty-day Senate recess may give rise to presidential authority to make recess ap-
    pointments.
    Congress’s provision for pro forma sessions during that twenty-day period does not have
    the legal effect of interrupting the recess for purposes of the Recess Appointments
    Clause.
    In this context, the President has discretion to conclude that the Senate is unavailable to
    perform its advise-and-consent function and may exercise his power to make recess
    appointments.

    MEMORANDUM OPINION FOR THE COUNSEL TO THE PRESIDENT *
    On December 17, 2011, the Senate agreed by unanimous consent to
    “adjourn and convene for pro forma sessions only, with no business
    conducted,” every Tuesday and Friday between that date and January 23,
    2012. 157 Cong. Rec. S8783 (daily ed. Dec. 17, 2011). During that peri-
    od, on January 3, 2012, the Senate convened one such pro forma session
    to begin the second session of the 112th Congress and adjourned less than
    a minute later under its prior agreement. 158 Cong. Rec. S1 (daily ed.
    Jan. 3, 2012); see also U.S. Const. amend. XX, § 2. You asked whether
    the President has authority under the Recess Appointments Clause, U.S.
    Const. art. II, § 2, cl. 3, to make recess appointments during the period
    between January 3 and January 23 notwithstanding the convening of
    periodic pro forma sessions. We advised you that he does. This opinion
    memorializes and elaborates on that advice.
    This Office has consistently advised that “a recess during a session of
    the Senate, at least if it is of sufficient length, can be a ‘Recess’ within the
    meaning of the Recess Appointments Clause” during which the President
    may exercise his power to fill vacant offices. Memorandum for Alberto R.
    * Editor’s Note: The Supreme Court considered the questions addressed in this opinion
    in NLRB v. Noel Canning, 
    573 U.S. 513
     (2014), and held that the Recess Appointments
    Clause empowers the President to fill vacancies during intrasession recesses “of substan-
    tial length,” but that the Senate is in session for purposes of the Clause during a pro forma
    session in which the Senate retains the capacity to conduct business under its rules. 
    Id. at 527, 550
    . The Court therefore held that three appointments made by President Obama
    during the period at issue in this opinion were invalid.

    Gonzales, Counsel to the President, from Jack L. Goldsmith III, Assistant
    Attorney General, Office of Legal Counsel, Re: Recess Appointments in
    the Current Recess of the Senate at 1 (Feb. 20, 2004) (“Goldsmith Memo-
    randum”). 1 Although the Senate will have held pro forma sessions regu-
    larly from January 3 through January 23, in our judgment, those sessions
    do not interrupt the intrasession recess in a manner that would preclude
    the President from determining that the Senate remains unavailable
    throughout to “‘receive communications from the President or participate
    as a body in making appointments.’” Intrasession Recess Appointments,

    , 272 (1989) (quoting Executive Power—Recess Ap-
    pointments, 33 Op. Att’y Gen. 20, 24 (1921) (“Daugherty Opinion”)).
    Thus, the President has the authority under the Recess Appointments
    Clause to make appointments during this period. The Senate could remove
    the basis for the President’s exercise of his recess appointment authority
    by remaining continuously in session and being available to receive and
    act on nominations, but it cannot do so by providing for pro forma ses-
    sions at which no business is to be conducted.
    I.
    Beginning in late 2007, and continuing into the 112th Congress, the
    Senate has frequently conducted pro forma sessions during recesses
    occurring within sessions of Congress. These pro forma sessions typically
    last only a few seconds, and apparently require the presence of only one
    Senator. 2 Senate orders adopted by unanimous consent provide in advance
    1  “A recess between sine die adjournment of one session and the convening of the next
    is also known as an intersession recess. A recess within a session is also known as an
    intrasession recess.” Henry B. Hogue & Richard S. Beth, Cong. Research Serv., Efforts to
    Prevent Recess Appointments Through Congressional Scheduling and Historical Recess
    Appointments During Short Intervals Between Sessions 3 n.6 (2011). “The number of
    days in a recess period is ordinarily calculated by counting the calendar days running
    from the day after the recess begins and including the day the recess ends.” Goldsmith

    order stating that “no action or debate” is to occur during pro forma ses-
    sions). 3 The Senate Majority Leader has stated that such pro forma ses-
    sions break a long recess into shorter adjournments, each of which might
    ordinarily be deemed too short to be considered a “recess” within the
    meaning of the Recess Appointments Clause, thus preventing the Presi-
    dent from exercising his constitutional power to make recess appoint-
    ments. See 154 Cong. Rec. S7558 (daily ed. July 28, 2008) (statement of
    Sen. Reid); see also 153 Cong. Rec. S14609 (daily ed. Nov. 16, 2007)
    (statement of Sen. Reid) (“[T]he Senate will be coming in for pro forma
    sessions . . . to prevent recess appointments.”).
    While this practice was initiated by Senate action, more recently the
    Senate’s use of such sessions appears to have been forced by actions of
    the House of Representatives. See generally Henry B. Hogue & Richard
    S. Beth, Cong. Research Serv., Efforts to Prevent Recess Appointments
    Through Congressional Scheduling and Historical Recess Appointments
    During Short Intervals Between Sessions 5–8 (2011). On May 25, 2011,
    twenty Senators noted the Senate’s use of pro forma sessions in 2007
    and “urge[d] [the Speaker of the House] to refuse to pass any resolution
    (daily ed. May 27, 2008) (noting that day’s pro forma session lasted from 9:15:02 until
    9:15:31 a.m.).
    3 We are aware of only two occasions in this period in which a Senate order did not
    provide that no business would be conducted in pro forma sessions held during a recess.
    On the first, the relevant order provided that there would be “no business conducted,
    except with the concurrence of the two leaders,” 154 Cong. Rec. S10,504 (daily ed.
    Oct. 2, 2008); on the second, the relevant order was silent, 
    id.
     at S6336 (daily ed. June 27,
    2008). It is unclear, however, whether the use of pro forma sessions on the latter occasion
    was intended to prevent recess appointments, as only one pro forma session was sched-
    uled during the ten-day recess. See 
    id. 17
    36 Op. O.L.C. 15
     (2012)
    to allow the Senate to recess or adjourn for more than three days for the
    remainder of the [P]resident’s term.” Press Release, Senator David

    pointments (May 25, 2011), http://vitter.senate.gov/public/index.cfm?
    FuseAction=PressRoom.PressReleases. The next month, eighty Repre-
    sentatives similarly requested that the Speaker, House Majority Leader,
    and House Whip take “all appropriate measures . . . to prevent any and
    all recess appointments by preventing the Senate from officially recess-
    ing for the remainder of the 112th Congress.” Letter for John Boehner,
    Speaker of the House, et al., from Jeff Landry, Member of Congress
    (June 15, 2011), http://landry.house.gov/sites/landry.house.gov/files/
    documents/Freshmen%20Recess%20Appointment%20Letter.pdf. Con-
    sistent with these requests, “no concurrent resolution of adjournment
    ha[s] been introduced in either chamber since May 12, 2011.” Henry B.
    Hogue, Cong. Research Serv., RS21308, Recess Appointments: Fre-
    quently Asked Questions 3 (rev. Dec. 12, 2011). And because the Con-
    stitution provides that “[n]either House, during the Session of Con-
    gress, shall, without the Consent of the other, adjourn for more than
    three days,” U.S. Const. art. I, § 5, cl. 4, both Houses have convened
    pro forma sessions during periods of extended absence.
    Public statements by some Members of the Senate reveal that they do
    not consider these pro forma sessions to interrupt a recess. See, e.g., 157
    Cong. Rec. S6826 (daily ed. Oct. 20, 2011) (statement of Sen. Inhofe)
    (referring to the upcoming “1-week recess”); id. at S5035 (daily ed. July
    29, 2011) (statement of Sen. Thune) (calling on the Administration to
    send trade agreements to Congress “before the August recess” even
    though “[w]e are not going to be able to consider these agreements until
    September”); id. at S4182 (daily ed. June 29, 2011) (statement of Sen.
    Sessions) (“Now the Senate is scheduled to take a week off, to go into
    recess to celebrate the Fourth of July[.]”); 156 Cong. Rec. at S8116–17
    (daily ed. Nov. 19, 2010) (statement of Sen. Leahy) (referring to the
    period when “the Senate recessed for the elections” as the “October re-
    cess”); 154 Cong. Rec. S7984 (daily ed. Aug. 1, 2008) (statement of Sen.
    Hatch) (referring to upcoming “5-week recess”); id. at S7999 (daily ed.
    Aug. 1, 2008) (statement of Sen. Dodd) (noting that Senate would be in
    “adjournment or recess until the first week in September”); id. at S7713
    (daily ed. July 30, 2008) (statement of Sen. Cornyn) (referring to the
    18

    upcoming “month-long recess”); see also id. at S2193 (daily ed. Mar. 13,
    2008) (statement of Sen. Leahy) (referring to the upcoming “2-week
    Easter recess”).
    Likewise, the Senate as a body does not uniformly appear to consider
    its recess broken by pre-set pro forma sessions. The Senate’s web page on
    the sessions of Congress, which defines a recess as “a break in House or
    Senate proceedings of three days or more, excluding Sundays,” treats such
    a period of recess as unitary, rather than breaking it into three-day seg-
    ments. See United States Senate, The Dates of Sessions of the Congress,
    http://www.senate.gov/reference/Sessions/sessionDates.htm (last visited
    ca. Jan. 2012). The Congressional Directory of the 112th Congress, pub-
    lished by Congress, see 44 U.S.C. § 721(a), does the same. See 2011–
    2012 Congressional Directory 538 n.2 (Joint Comm. on Printing, 112th
    Cong., comp. 2011). More substantively, despite the pro forma sessions,
    the Senate has taken special steps to provide for the appointment of con-
    gressional personnel during longer recesses (including this one), indicat-
    ing that the Senate recognizes that it is not in session during this period
    for the purpose of making appointments under ordinary procedures. 4 And
    when messages are received from the President during the recess, they are
    not laid before the Senate and entered into the Congressional Record until
    the Senate returns for a substantive session, even if pro forma sessions are
    4 See, e.g., 157 Cong. Rec. S8783 (daily ed. Dec. 17, 2011) (providing that “notwith-
    standing the upcoming recess or adjournment of the Senate, the President of the Senate,
    the President pro tempore, and the majority and minority leaders [are] authorized to make
    appointments to commissions, committees, boards, conferences, or interparliamentary
    conferences authorized by the law, by concurrent action of the two Houses, or by order of
    the Senate”); id. at S7876 (daily ed. Nov. 18, 2011) (similar); id. at S5292 (daily ed. Aug.
    2, 2011) (similar); id. at S3463 (daily ed. May 26, 2011) (similar); 156 Cong. Rec. S7775
    (daily ed. Sept. 29, 2010) (similar); 154 Cong Rec. S10,958 (daily ed. Dec. 11, 2008)
    (similar); id. at S10,776 (daily ed. Nov. 20, 2008) (similar); id. at S10,427 (daily ed. Oct.
    2, 2008) (similar); id. at S8077 (daily ed. Aug. 1, 2008) (similar); id. at S6332 (daily ed.
    June 27, 2008) (similar); id. at S4848 (daily ed. May 22, 2008) (similar); id. at S2190

    2007) (similar). The Senate has taken similar steps before recesses that are not punctuated
    by pro forma sessions. See, e.g., 156 Cong. Rec. S6974 (daily ed. Aug. 5, 2010) (provid-
    ing for appointment authority before an intrasession recess expected to last for thirty-nine
    days); 153 Cong. Rec. S10,991 (daily ed. Aug. 3, 2007) (same, recess of thirty-two days).
    19
    
    36 Op. O.L.C. 15
     (2012)
    convened in the meantime. 5 On the other hand, we have been informed
    that at least during the August 2008 recess, the Senate Executive Clerk
    did not return pending nominations when the Senate went into recess
    pursuant to Senate Standing Rule XXXI, which provides for the return of
    nominations that have not been acted upon when the Senate recesses “for
    more than thirty days.” Senate Rule XXXI(6), Standing Rules of the
    Senate, in Senate Manual, S. Doc. No. 112-1, at 58 (2011) (“Senate
    Standing Rules”). This omission may reflect the Executive Clerk’s treat-
    ment of that impending recess as a series of shorter adjournments rather
    than a single thirty-eight-day recess.
    II.
    To address the President’s authority to make recess appointments dur-
    ing a recess including pro forma sessions, we consider two distinct issues:
    The first is whether the President has authority to make a recess appoint-
    ment during the recess at issue here, an intrasession recess of twenty days.
    We conclude that he does. The opinions of the Attorney General and this
    Office, historical practice, and the limited judicial authority that exists all
    provide strong support for that conclusion.
    Thereafter, we consider whether the President is disabled from making
    an appointment when the recess is punctuated by periodic pro forma
    sessions at which Congress has declared in advance that no business is to
    be conducted. Based primarily on the traditional understanding that the
    Recess Appointments Clause is to be given a practical construction focus-
    ing on the Senate’s ability to provide advice and consent to nominations,
    we conclude that while Congress can prevent the President from making
    any recess appointments by remaining continuously in session and availa-
    ble to receive and act on nominations, it cannot do so by conducting pro
    forma sessions during a recess. The question is a novel one, and the
    5 See, e.g., 157 Cong. Rec. S7905 (daily ed. Nov. 28, 2011) (message from the Presi-
    dent “received during adjournment of the Senate on November 21, 2011,” laid before the
    Senate); 
    id.
     at S7881 (daily ed. Nov. 25, 2011) (record of pro forma session with no
    mention of receipt of presidential message); 
    id.
     at S7879 (daily ed. Nov. 22, 2011)
    (same); S6916 (daily ed. Oct. 31, 2011) (message from the President “received during
    adjournment of the Senate on October 25, 2011,” laid before the Senate); 
    id.
     at S6895
    (daily ed. Oct. 27, 2011) (record of pro forma session with no mention of receipt of
    presidential message).

    substantial arguments on each side create some litigation risk for such
    appointments. We draw on the analysis developed by this Office when it
    first considered the issue. See Memorandum to File, from John P. Elwood,
    Deputy Assistant Attorney General, Office of Legal Counsel, Re: Lawful-
    ness of Making Recess Appointment During Adjournment of the Senate
    Notwithstanding Periodic “Pro Forma Sessions” (Jan. 9, 2009).
    A.
    The Recess Appointments Clause of the Constitution provides that
    “[t]he President shall have Power to fill up all Vacancies that may happen
    during the Recess of the Senate, by granting Commissions which shall
    expire at the End of their next Session.” U.S. Const. art. II, § 2, cl. 3. The
    Department of Justice “has long interpreted the term ‘recess’ to include
    intrasession recesses if they are of substantial length.” Intrasession Recess
    Appointments, 13 Op. O.L.C. at 272; see also Goldsmith Memorandum at
    1–2; Recess Appointments During an Intrasession Recess, 
    16 Op. O.L.C. 15
    , 15–16 (1992); Recess Appointments—Compensation (5 U.S.C. § 5503),
    
    3 Op. O.L.C. 314
    , 316 (1979); Recess Appointments, 41 Op. Att’y Gen.
    463, 468 (1960); Daugherty Opinion, 33 Op. Att’y Gen. at 21–22, 25.
    Under a framework first articulated by Attorney General Daugherty in
    1921, and subsequently reaffirmed and applied by several opinions of
    the Attorney General and this Office, the “constitutional test for whether
    a recess appointment is permissible is whether the adjournment of the
    Senate is of such duration that the Senate could ‘not receive communica-
    tions from the President or participate as a body in making appoint-
    ments.’” Intrasession Recess Appointments, 13 Op. O.L.C. at 272 (quot-
    ing Daugherty Opinion, 33 Op. Att’y Gen. at 24). 6 Although “the line of
    6 In 1868, Attorney General Evarts approved the contemplated appointments of three
    officials during a fifty-six-day intrasession recess of the Senate without remarking upon
    the nature of the recess. See Case of District Attorney for Eastern District of Pennsylva-
    nia, 12 Op. Att’y Gen. 469, 469–70 (1868) (observing that the office “is now vacant
    during the recess of the Senate” and opining that “it is competent for the President to
    grant a commission”); see also Case of the Collectorship of New Orleans, 12 Op. Att’y
    Gen. 449 (1868); Case of the Collectorship of Customs for Alaska, 12 Op. Att’y Gen. 455
    (1868). It is possible that Attorney General Evarts was not aware that the Senate had
    merely adjourned to a date certain: he referred in each opinion to the “late session” of the
    Senate. See, e.g., 12 Op. Att’y Gen. at 451. Attorney General Knox, too, was apparently
    21
    
    36 Op. O.L.C. 15
     (2012)
    demarcation can not be accurately drawn” in determining whether an
    intrasession recess is of sufficient length to permit the President to make
    a recess appointment, “the President is necessarily vested with a large,
    although not unlimited, discretion to determine when there is a real and
    genuine recess making it impossible for him to receive the advice and
    consent of the Senate.” Daugherty Opinion, 33 Op. Att’y Gen. at 25; see
    also 
    id.
     (“Every presumption is to be indulged in favor of the validity of
    whatever action [the President] may take.”); The Constitutional Separa-
    tion of Powers Between the President and Congress, 
    20 Op. O.L.C. 124
    ,
    161 (1996) (“Dellinger Opinion”) (“[T]he President has discretion to
    make a good-faith determination of whether a given recess is adequate
    to bring the Clause into play.”). “Ultimately, resolution of the question
    whether an adjournment is of sufficient duration to justify recess ap-
    pointments requires the application of judgment to particular facts.”
    Intrasession Recess Appointments, 13 Op. O.L.C. at 273.
    We have little doubt that a twenty-day recess may give rise to presiden-
    tial authority to make recess appointments. Attorneys General and this
    Office have repeatedly affirmed the President’s authority to make recess
    appointments during intrasession recesses of similar or shorter length.
    See, e.g., Goldsmith Memorandum at 2–3 (recognizing President’s author-
    ity to make a recess appointment during an intrasession recess of eleven
    days); Recess Appointments During an Intrasession Recess, 16 Op.
    O.L.C. at 15–16 (same, eighteen days); Intrasession Recess Appointments,
    13 Op. O.L.C. at 272–73 (thirty-three days); Recess Appointments, 41 Op.
    Att’y Gen. at 464–65 (thirty-six days); Daugherty Opinion, 33 Op. Att’y
    Gen. at 25 (twenty-eight days). 7
    unaware of this fact when he cited one of these opinions to support his conclusion that it
    is only the “period following the final adjournment for the session which is the recess
    during which the President has power to fill vacancies” and remarked that “[t]he opinions
    of Mr. Wirt . . . and all the other opinions on this subject relate only to appointments
    during the recess of the Senate between two sessions of Congress.” Appointments of
    Officers—Holiday Recess, 23 Op. Att’y Gen. 599, 601–02 (1901). The Daugherty Opinion
    reversed Attorney General Knox’s conclusion about appointments in intrasession recess-
    es.
    7 In 1985, the Office “cautioned against a recess appointment during [what was mis-
    takenly believed to be] an 18-day intrasession recess,” Intrasession Recess Appointments,

    The recess appointment practice of past Presidents confirms the views
    expressed in these opinions. See Am. Ins. Ass’n v. Garamendi,

    they were brief. See Congressional Directory 522–25 (listing five in-
    trasession recesses before the Civil War, ranging from five to twelve days
    in length). But as intrasession recesses became common, so too did in-
    trasession recess appointments. President Johnson is believed to have

    dents have all made appointments during intrasession recesses of fourteen
    days or fewer. 9
    There is significant (albeit not uniform) evidence that the Executive
    Branch’s view that recess appointments during intrasession recesses are
    constitutional has been accepted by Congress and its officers. Most rele-
    vant, in our view, is the Pay Act, 5 U.S.C. § 5503 (2006), which sets out
    the circumstances in which a recess appointee may be paid a salary from
    the Treasury. The Attorney General has long taken the position that the
    Act constitutes congressional acquiescence to recess appointments under
    circumstances where the Act would permit payment. See Recess Appoint-
    ments, 41 Op. Att’y Gen. at 466. In 1948, the Comptroller General con-
    sidered whether the Act permitted the payment of officials appointed
    during an intrasession recess. Appointments—Recess Appointments,

     (1948). After acknowledging the “accepted view” that an
    intrasession recess “is a recess during which an appointment may properly
    be made,” the Comptroller General concluded that the Act was intended
    to permit payment to all who are appointed “during periods when the

    pointments during a twelve-day recess, and four appointments during a fourteen-day

    appointment during an eleven-day recess, and seventeen appointments across several

    Recess Appointments Amid Pro Forma Senate Sessions
    Senate is not actually sitting and is not available to give its advice and
    consent in respect to the appointment, irrespective of whether the recess
    of the Senate is attributable to a final adjournment sine die or to an ad-
    journment to a specified date.” Id. at 34, 37. “Considering that the Comp-
    troller General is an officer in the legislative branch, and charged with the
    protection of the fiscal prerogatives of the Congress, his full concurrence
    in the position taken by the Attorney General . . . is of signal signifi-
    cance,” Recess Appointments, 41 Op. Att’y Gen. at 469, and in the more
    than sixty years since the opinion was issued, Congress has not amended
    the statute to compel a different result. 10
    While there is little judicial precedent addressing the President’s au-
    thority to make intrasession recess appointments, what decisions there are
    uniformly conclude that the President does have such authority. In the
    only federal court of appeals decision squarely on point, the en banc
    Eleventh Circuit upheld the recess appointment of a judge made during an
    eleven-day intrasession recess. See Evans, 
    387 F.3d at 1224
    –26 (conclud-
    ing “Recess of the Senate” as used in the Recess Appointments Clause
    includes intrasession recesses and declining to set a lower limit on their
    length). But see 
    id. at 1228 n.2
     (“Although I would not reach this ques-
    10 Certain language in an 1863 report of the Senate Judiciary Committee could be read
    to suggest that the Committee believed that recess appointments could be made only
    during intersession recesses. See S. Rep. No. 37-80, at 3 (1863) (“It cannot, we think, be
    disputed that the period of time designated in the clause as ‘the recess of the Senate,’
    includes the space beginning with the indivisible point of time which next follows that at
    which it adjourned, and ending with that which next precedes the moment of the com-
    mencement of their next session.”). But the question addressed by the Committee in 1863
    related to timing of the occurrence of the vacancy, not the nature of the recess during
    which the vacancy occurred. Moreover, a subsequent report by the Committee defined a
    recess functionally in terms that have since been adopted by the Attorney General and this
    Office as setting forth the test for determining when an intrasession recess is of sufficient
    length to give rise to the President’s power under the Recess Appointments Clause. See
    S. Rep. No. 58-4389, at 2 (1905) (defining a recess as “the period of time . . . when,
    because of its absence, [the Senate] can not receive communications from the President or
    participate as a body in making appointments”); see also infra pp. 32–33.
    A draft legal brief prepared, but never filed, by the Senate Legal Counsel in 1993 took
    the position that “the text and purpose of the Recess Appointments Clause both demon-
    strate that the recess power is limited to Congress’ annual recess between sessions.” 139
    Cong. Rec. 15,267, 15,268 (1993). Because a resolution directing the Counsel to appear in
    the litigation was never offered, however, it is unclear whether the views expressed in the
    brief garnered the support of a majority of the Senate.

    tion, the text of the Constitution as well as the weight of the historical
    record strongly suggest that the Founders meant to denote only inter-
    session recesses.” (Barkett, J., dissenting)). Lower courts, too, have rec-
    ognized the President’s power to make intrasession recess appointments.
    See Nippon Steel Corp. v. Int’l Trade Comm’n, 
    239 F. Supp. 2d 1367
    ,
    1374 n.13 (Ct. Int’l Trade 2002) (“The long history of the practice (since
    at least 1867) without serious objection by the Senate . . . demonstrates
    the legitimacy of these appointments.”); Gould v. United States, 
    19 Ct. Cl. 593
    , 595–96 (1884) (“We have no doubt that a vacancy occurring while
    the Senate was thus temporarily adjourned . . . could be and was legally
    filled by the appointment of the President alone.” (dictum)). The Supreme
    Court, however, has never decided the issue. 11
    Due to this limited judicial authority, we cannot predict with certainty
    how courts will react to challenges of appointments made during intrases-
    sion recesses, particularly short ones. 12 If an official appointed during the
    current recess takes action that gives rise to a justiciable claim, litigants
    might challenge the appointment on the ground that the Constitution’s
    reference to “the Recess of the Senate” contemplates only the recess at the
    end of a session. That argument and the Department of Justice’s response
    11 Justice Stevens filed a statement respecting the denial of certiorari in Evans express-
    ing his view that the “case . . . raises significant constitutional questions regarding the
    President’s intrasession appointment” of a circuit judge and that “it would be a mistake to
    assume that our disposition of this petition constitutes a decision on the merits of whether
    the President has the constitutional authority to fill future Article III vacancies, such as
    vacancies on this Court, with appointments made absent consent of the Senate during
    short intrasession ‘recesses.’” Evans v. Stephens, 
    544 U.S. 942
    , 942–43 (2005) (Stevens,
    J., respecting denial of certiorari). It is unclear whether the Justice’s concerns related
    specifically to recess appointments of Article III judges or extended to executive branch
    appointments.
    12 Scholarly opinion is divided on the proper interpretation of the Recess Appoint-
    ments Clause, although advocates for a more limited recess appointment power recognize
    that their view has not prevailed. Compare Edward A. Hartnett, Recess Appointments of
    Article III Judges: Three Constitutional Questions, 26 Cardozo L. Rev. 377, 424 (2005)
    (“[T]he recess appointment power is best understood as available during both intersession
    and intrasession Senate recesses of more than three days.”), with Michael B. Rappaport,
    The Original Meaning of the Recess Appointments Clause, 52 UCLA L. Rev. 1487, 1487
    (2005) (arguing that “the Constitution permits recess appointments only during an in-
    tersession recess,” but acknowledging that “[t]he prevailing interpretation . . . allows the
    President to makes recess appointments . . . during intrasession recesses of ten days and
    perhaps of even shorter duration”).
    26
    Recess Appointments Amid Pro Forma Senate Sessions
    have been discussed at length during litigation over a judicial recess
    appointment. See, e.g., Brief for the Intervenor United States, Stephens,
    
    387 F.3d 1220
     (No. 02-16424); Response Brief of Plaintiffs-Appellees
    and United States Senator Edward M. Kennedy as Amicus Curiae Sup-
    porting Plaintiffs-Appellees, Stephens, 
    387 F.3d 1220
     (No. 02-16424); see
    also supra note 11.
    We conclude that the President’s authority to make recess appointments
    extends to an intrasession recess of twenty days.
    B.
    The second question we consider is whether Congress can prevent the
    President from making appointments during a recess by providing for pro
    forma sessions at which no business is to be conducted, where those pro
    forma sessions are intended to divide a longer recess into a series of
    shorter adjournments, each arguably too brief to support the President’s
    recess appointment authority. We believe that Congress’s provision for
    pro forma sessions of this sort does not have the legal effect of interrupt-
    ing the recess of the Senate for purposes of the Recess Appointments
    Clause and that the President may properly conclude that the Senate is
    unavailable for the overall duration of the recess. 13
    13 Because we conclude that pro forma sessions do not have this effect, we need not
    decide whether the President could make a recess appointment during a three-day
    intrasession recess. This Office has not formally concluded that there is a lower limit to
    the duration of a recess within which the President can make a recess appointment.
    Attorney General Daugherty suggested in dictum in his 1921 opinion that “an adjourn-
    ment of 5 or even 10 days [could not] be said to constitute the recess intended by the
    Constitution,” 33 Op. Att’y Gen. at 25. As a result, “[t]his Office has generally advised
    that the President not make recess appointments, if possible, when the break in continuity
    of the Senate is very brief,” The Pocket Veto: Historical Practice and Judicial Precedent,
    
    6 Op. O.L.C. 134
    , 149 (1982); see, e.g., Recess Appointments—Compensation (5 U.S.C.
    § 5503), 
    3 Op. O.L.C. 314
    , 315–16 (1979) (describing informal advice against making
    recess appointments during a six-day intrasession recess in 1970). Notwithstanding
    Attorney General Daugherty’s caution, we advised in 1996 that “recess appointments
    during [a] 10-day intrasession recess would be constitutionally defensible,” although they
    would “pose significant litigation risks.” Memorandum for John M. Quinn, Counsel to the
    President, from Walter Dellinger, Assistant Attorney General, Office of Legal Counsel,
    Re: Recess Appointments (May 29, 1996). And both this Office and the Department of
    Justice in litigation have recognized the argument that “the three days set by the Constitu-
    tion as the time during which one House may adjourn without the consent of the other,

    The Appointments Clause of the Constitution provides that the Presi-
    dent “shall nominate, and by and with the Advice and Consent of the
    Senate, shall appoint Ambassadors, other public Ministers and Consuls,
    Judges of the supreme Court, and all other Officers of the United States.”
    U.S. Const. art. II, § 2, cl. 2. The Recess Appointments Clause immediate-
    ly follows and confers on the President the “Power to fill up all Vacancies
    that may happen during the Recess of the Senate, by granting Commis-
    sions which shall expire at the End of their next Session.” Id. art. II, § 2,
    cl. 3. The Clause was adopted at the Constitutional Convention without
    debate. See 2 The Records of the Federal Convention of 1787, at 533, 540
    (Max Farrand ed., rev. ed. 1966). 14 Alexander Hamilton described the
    Clause in The Federalist as providing a “supplement” to the President’s
    appointment power, establishing an “auxiliary method of appointment, in
    cases to which the general method was inadequate.” The Federalist No.
    U.S. Const. art. I, § 5, cl. 4, is also the length of time amounting to a ‘Recess’ under the

    recess appointment power” (capitalization omitted)).
    14 The Clause, which was proposed by a North Carolina delegate, is generally consid-
    ered to have been based on a similar provision then in the North Carolina Constitution.
    See 2 David K. Watson, The Constitution of the United States 988 (1910) (“The [Recess
    Appointments Clause] was doubtless taken from the Constitution of North Carolina,
    which contained a similar clause.” (footnote omitted)); Thomas A. Curtis, Note, Recess
    Appointments to Article III Courts: The Use of Historical Practice in Constitutional
    Interpretation, 84 Colum. L. Rev. 1758, 1770 n.71 (1984) (noting that the provision was
    proposed by a delegate from North Carolina; that the language tracks that of the North
    Carolina provision; and that the federal power is similar in scope to the power in North
    Carolina’s Constitution at that time). Because the North Carolina legislature was then
    generally responsible for appointments, the executive could make appointments only
    when the legislature was not in session to do so.
    28
    Recess Appointments Amid Pro Forma Senate Sessions
    67, at 409 (Clinton Rossiter ed., 1961). The Clause was necessary because
    “it would have been improper to oblige [the Senate] to be continually in
    session for the appointment of officers,” and it “might be necessary for
    the public service to fill [vacancies] without delay.” Id. at 410.
    Other contemporaneous writings likewise emphasize that the recess
    appointment power is required to address situations in which the Senate is
    unable to provide advice and consent on appointments. See 4 The Debates
    in the Several State Conventions on the Adoption of the Federal Constitu-
    tion as Recommended by the General Convention at Philadelphia in 1787,
    at 135–36 (Jonathan Elliott ed., 2d ed. 1836) (“Elliott’s Debates”) (state-
    ment of Archibald Maclaine at North Carolina ratification convention)
    (July 28, 1788) (“Congress are not to be sitting at all times; they will only
    sit from time to time, as the public business may render it necessary.
    Therefore the executive ought to make temporary appointments, as well as
    receive ambassadors and other public ministers. This power can be vested
    nowhere but in the executive, because he is perpetually acting for the
    public; for, though the Senate is to advise him in the appointment of
    officers, &c., yet, during the recess, the President must do this business,
    or else it will be neglected; and such neglect may occasion public incon-
    veniences.”); cf. Letters of Cato IV, reprinted in 2 The Complete Anti-
    Federalist 114 (Herbert J. Storing ed., 1981) (“Though the president,
    during the sitting of the legislature, is assisted by the senate, yet he is
    without a constitutional council in their recess . . . .”). 15 Thus, from the
    days of the Founding, the Recess Appointments Clause has been consid-
    ered implicated when the Senate is not “in session for the appointment of
    officers.” The Federalist No. 67, at 410.
    Nineteenth-century sources reflect this understanding. Justice Story
    framed the issue in terms of the Senate’s ability to review nominations:
    15 See also 2 Elliott’s Debates 513 (statement of James Wilson at Pennsylvania ratifica-
    tion convention) (“[T]here is only left the power of concurring in the appointment of
    officers; but care is taken, in this Constitution, that this branch of business may be done
    without [the Senate’s] presence”); id. at 534 (statement of Thomas M’Kean) (Dec. 11,
    1787) (“Nor need the Senate be under any necessity of sitting constantly, as has been
    alleged; for there is an express provision made to enable the President to fill up all
    vacancies that may happen during their recess[.]”); 3 Elliott’s Debates 409–10 (statement
    of James Madison at the Virginia convention) (“There will not be occasion for the contin-
    ual residence of the senators at the seat of government. . . . It is observed that the Presi-
    dent, when vacancies happen during the recess of the Senate, may fill them till it meets.”).

    36 Op. O.L.C. 15
     (2012)
    “There was but one of two courses to be adopted [at the Founding]; either,
    that the senate should be perpetually in session, in order to provide for the
    appointment of officers; or, that the president should be authorized to
    make temporary appointments during the recess, which should expire,
    when the senate should have had an opportunity to act on the subject.”
    3 Joseph Story, Commentaries on the Constitution of the United States
    § 1551, at 410 (1833); id. § 1552, at 411 (discussing renomination when
    “the senate is assembled”). And as early as the Monroe Administration,
    the Executive Branch’s analysis of the Clause had begun to focus on the
    availability of the Senate to be consulted on nominations. See, e.g., Ex-
    ecutive Authority to Fill Vacancies, 1 Op. Att’y Gen. 631, 633 (1823)
    (“[A]ll vacancies which . . . happen to exist at a time when the Senate
    cannot be consulted as to filling them, may be temporarily filled by the
    President[.]”) (emphasis added); Power of President to Fill Vacancies,
    3 Op. Att’y Gen. 673, 676 (1841) (“[T]he convention very wisely provid-
    ed against the possibility of such evils [i.e., “interregna in the executive
    powers”] by enabling and requiring the President to keep full every office
    of the government during a recess of the Senate, when his advisers could
    not be consulted [.]”) (emphasis added); Power of President to Appoint to
    Office during Recess of Senate, 4 Op. Att’y Gen. 523, 526 (1846) (“[T]he
    vacancy happened at a time, and continues now to exist, when the Presi-
    dent cannot obtain the advice and consent of his constitutional advis-
    ers. . . . [T]his vacancy happening from the inaction of the Senate on the
    nomination made[] is within the meaning of the [Recess Appointments
    Clause], and may be filled by an Executive Appointment.” (emphasis
    added)).
    Opinions of the Attorney General have construed the Clause in order to
    fulfill its purpose that there be an uninterrupted power to fill federal
    offices. Thus, Attorney General Wirt advised in 1823 that “whensoever a
    vacancy shall exist which the public interests require to be immediately
    filled, and in filling which, the advice and consent of the Senate cannot be
    immediately asked, because of their recess, the President shall have the
    power of filling it by an appointment” because “[t]he substantial purpose
    of the constitution was to keep these offices filled; and powers adequate
    to this purpose were intended to be conveyed.” Executive Authority to Fill
    Vacancies, 1 Op. Att’y Gen. at 632; see also Power of President to Fill
    Vacancies, 3 Op. Att’y Gen. at 675 (affirming the President’s power to
    30
    Recess Appointments Amid Pro Forma Senate Sessions
    make a second recess appointment after the Senate failed to act on a
    nomination during the term of the first appointment because “the Presi-
    dent, charged with the high duty of giving full effect to the law, must have
    a power like its own existence—perpetual”); President’s Power to Fill
    Vacancies in Recess of the Senate, 12 Op. Att’y Gen. 32, 38 (1866) (same,
    because “as to the executive power, it is always to be in action, or in
    capacity for action; and . . . to meet this necessity, there is a provision . . .
    against vacancies in all the subordinate offices, and that at all times there
    is a power to fill such vacancies”). 16
    Subsequent Attorneys General and, later, this Office have continued to
    place central importance on the Senate’s availability to give advice and
    consent. In his seminal opinion concluding that a significant intrasession
    adjournment is a “recess” in which recess appointments can be made,
    Attorney General Daugherty focused on this point: “Regardless of wheth-
    er the Senate has adjourned or recessed, the real question . . . is whether in
    a practical sense the Senate is in session so that its advice and consent
    can be obtained.” Daugherty Opinion, 33 Op. Att’y Gen. at 21–22 (sec-
    ond emphasis added); see also id. at 25 (“Is the Senate absent so that it
    can not receive communications from the President or participate as a
    body in making appointments?”). Thus, in determining whether an intra-
    session adjournment constitutes a recess in the constitutional sense, the

    16 Indeed, in construing the phrase “happen during the Recess” in the Recess Ap-
    pointments Clause to mean “happen to exist” rather than originate in the recess, Attorney
    General Wirt identified two possibilities: one was “most accordant with the letter of the
    constitution; the second, most accordant with its reason and spirit.” Executive Authority

    which is compatible with its spirit, reason, and purpose.” Id. at 633. The courts have
    subsequently endorsed the construction adopted by Wirt. See, e.g., Evans,

    O.L.C. at 272. That understanding has been embraced by some prominent
    commentators as well. See Louis Fisher, Constitutional Conflicts between
    Congress and the President 38 (5th ed. 2007) (“A temporary recess of the
    Senate, ‘protracted enough to prevent that body from performing its
    functions of advising and consenting to executive nominations,’ permits
    the President to make recess appointments.” (quoting Recess Appoint-
    ments, 41 Op. Att’y Gen. at 466)).
    Significantly, a century ago, the Senate Judiciary Committee adopted a
    functional understanding of the term “recess” that focuses on the Senate’s
    ability to conduct business. In rejecting the theory that President Theodore
    Roosevelt could make recess appointments during a brief “constructive
    recess” between two sessions of Congress, the Committee wrote of the
    Recess Appointments Clause:
    It was evidently intended by the framers of the Constitution that [the
    word “recess”] should mean something real, not something imagi-
    nary; something actual, not something fictitious. They used the word
    as the mass of mankind then understood it and now understand it. It
    means, in our judgment, . . . the period of time when the Senate is
    not sitting in regular or extraordinary session as a branch of the
    Congress, or in extraordinary session for the discharge of executive
    functions; when its members owe no duty of attendance; when its
    Chamber is empty; when, because of its absence, it can not receive
    communications from the President or participate as a body in mak-
    ing appointments. . . . Its sole purpose was to render it certain that at
    all times there should be, whether the Senate was in session or not,
    an officer for every office, entitled to discharge the duties thereof.
    S. Rep. No. 58-4389, at 2 (1905) (second emphasis added); see also
    Daugherty Opinion, 33 Op. Att’y Gen. at 24 (noting that this report was
    “most significant of all” authorities in supporting the conclusion that a
    substantial intrasession adjournment was a constitutional “recess”). The
    Senate continues to cite that report as an authoritative source “on what
    constitutes a ‘Recess of the Senate.’” Riddick’s Senate Procedure 947 &
    n.46 (1992), http://www.gpo.gov/fdsys/pkg/GPO-RIDDICK-1992/pdf/
    GPO-RIDDICK-1992-88.pdf (citing report). The Comptroller General
    attributed a similar understanding to the entire Congress when he opined
    that the “primary purpose” of the Pay Act was
    32
    Recess Appointments Amid Pro Forma Senate Sessions
    to relieve “recess appointees” of the burden of serving without com-
    pensation during periods when the Senate is not actually sitting and
    is not available to give its advice and consent in respect to the ap-
    pointment, irrespective of whether the recess of the Senate is at-
    tributable to a final adjournment sine die or to an adjournment to a
    specified date.

    Guided by these principles, we conclude that the President may deter-
    mine that pro forma sessions at which no business is to be conducted do
    not interrupt a Senate recess for purposes of the Recess Appointments
    Clause. Our conclusion rests on three considerations.
    First, both the Framers’ original understanding of the Recess Appoint-
    ments Clause and the longstanding views of the Executive and Legislative
    Branches support the conclusion that the President may make recess
    appointments when he determines that, as a practical matter, the Senate is
    not available to give advice and consent to executive nominations. The
    Recess Appointments Clause was adopted to allow the President to fill
    offices when the Senate was not “in session for the appointment of offic-
    ers.” The Federalist No. 67, at 410 (Alexander Hamilton). And, from the
    early days of the Republic, the Executive has taken the position that “all
    vacancies which . . . happen to exist at a time when the Senate cannot be
    consulted as to filling them, may be temporarily filled by the President.”
    Executive Authority to Fill Vacancies, 1 Op. Att’y Gen. at 633. Likewise,
    in 1905, the Senate Judiciary Committee defined “recess” as used in the
    Clause to be the period of time when the Senate cannot “participate as a
    body in making appointments.” S. Rep. No. 58-4389, at 2.
    We do not believe that the convening of periodic pro forma sessions
    precludes the President from determining that the Senate is unavailable
    during an intrasession recess otherwise long enough to support the Presi-
    dent’s recess appointment authority. During the last three Congresses,
    such sessions ordinarily have lasted only a few seconds. See, e.g., 157
    Cong. Rec. D1404 (daily ed. Dec. 30, 2011) (noting that day’s pro forma
    session lasted from 11:00:02 until 11:00:34 a.m.); see also supra note 2.
    33
    
    36 Op. O.L.C. 15
     (2012)
    Records of the sessions typically do not disclose the presence of any
    Senator other than the single convening member. See, e.g., 157 Cong.
    Rec. S8793 (daily ed. Dec. 30, 2011) (reflecting the presence of only
    Senator Reed). And importantly, the pertinent Senate order states in
    advance that there is to be “no business conducted” during the ensuing
    sessions. See, e.g., 157 Cong. Rec. S8783 (daily ed. Dec. 17, 2011); see
    also supra pp. 16–17. 17 The purpose of these sessions avowedly is not to
    conduct business; instead, either the Senate has intended to prevent the
    President from making recess appointments during its absence or the
    House has intended to require the Senate to remain in session (toward the
    same end). See supra pp. 17–18; see also Henry B. Hogue, Cong. Re-
    search Serv., RS21308, Recess Appointments: Frequently Asked Ques-
    tions 3 (rev. Mar. 2008) (noting use of such sessions “for the stated pur-
    pose of preventing [recess] appointments”).
    Under these circumstances, the President could properly consider the
    pertinent intrasession recess period to be one during which the Senate is
    not genuinely “capable of exercising its constitutional function of advis-
    ing and consenting to executive nominations,” Recess Appointments, 41
    Op. Att’y Gen. at 467; see Dellinger Opinion, 20 Op. O.L.C. at 161 (not-
    ing the President’s “discretion to make a good-faith determination of
    whether a given recess is adequate to bring the Clause into play”); Daugh-
    17 The Senate’s rules would also prevent it from acting on nominations or transacting
    other legislative business during such sessions if, as expected, only a few Senators are
    present. Under those rules, a quorum consists of “a majority of the Senators duly chosen
    and sworn.” Senate Rule VI(1), Senate Standing Rules at 5. Whenever it is determined
    that “a quorum is not present, a majority of the Senators present may direct the Sergeant
    at Arms to request, and, when necessary, to compel the attendance of the absent Sena-
    tors, which order shall be determined without debate; and pending its execution, and
    until a quorum shall be present, no debate nor motion, except to adjourn, or to recess
    pursuant to a previous order entered by unanimous consent, shall be in order.” Senate
    Rule VI(4), id. at 5–6; see also Riddick’s Senate Procedure at 1046 (“No debate nor
    business can be transacted in the absence of a quorum[.]”). We recognize that, as a
    practical matter, neither the scheduling order nor the quorum requirement will always
    prevent the Senate from acting without a quorum through unanimous consent. Indeed,
    the Senate has occasionally enacted legislation by unanimous consent during pro forma
    sessions. See infra p. 45. But as more fully explained below, we do not believe that this
    sporadic practice requires the President to consider the Senate available to perform its
    constitutional functions when it is in recess and, particularly, when it has provided by
    order that no business will be conducted.
    34
    Recess Appointments Amid Pro Forma Senate Sessions
    erty Opinion, 33 Op. Att’y Gen. at 25 (discussing the President’s “large,
    although not unlimited, discretion to determine when there is a real and
    genuine recess making it impossible for him to receive the advice and
    consent of the Senate”). Indeed, as noted above, presidential messages
    delivered to the Senate during previous recesses were not laid before that
    body and entered into the Congressional Record until after the recess was
    over, notwithstanding the convening of pro forma sessions before that
    date. See supra note 5 & accompanying text. And the Senate has made
    special arrangements for the appointment of its own officers during the
    recess, in apparent recognition of the fact that it will not be in session for
    the purpose of making appointments under its usual procedures. See supra
    note 4 & accompanying text. “[T]he rationale for treating substantial
    intrasession adjournments as ‘recesses’ for purposes of the Recess Ap-
    pointments Clause is that substantial adjournments prevent the Senate
    from acting on nominations.” Intrasession Recess Appointments, 13 Op.
    O.L.C. at 273. By the same reasoning, brief pro forma sessions of this
    sort, at which the Senate is not capable of acting on nominations, may be
    properly viewed as insufficient to terminate an ongoing recess for purpos-
    es of the Clause. 18
    This view of the effect of pro forma sessions on the President’s recess
    appointment power finds additional support in one of this Office’s prior
    opinions, Recess Appointments During an Intrasession Recess, 
    16 Op. O.L.C. 15
    . That opinion addressed the propriety of making recess ap-
    pointments during a recess that began on January 3, 1992, and ended on
    January 21, 1992. We noted that, aside from a “brief formal session on
    January 3” at which the body conducted no business (and which evidently
    was held to address the terms of the Twentieth Amendment, see infra note
    22), the Senate had been in recess since November 27, 1991. 16 Op.
    O.L.C. at 15 n.1. Thus, we observed that “[f]or practical purposes with
    18 In reaching this conclusion, we need not look behind the actual terms of the Senate’s
    orders. The Senate itself labels the sessions “pro forma” and specifies that there is to be
    “no business conducted” during those sessions. See, e.g., 157 Cong. Rec. S8783 (daily ed.
    Dec. 17, 2011). These orders make clear that the Senate cannot perform its advise-and-
    consent role during the pro forma sessions. The issue we have been asked to address
    relates to the legal effect of such sessions on the intrasession recess, and the Senate orders
    on their face warrant the conclusion that the Senate is unavailable to provide advice and
    consent during the intrasession recess.
    35
    
    36 Op. O.L.C. 15
     (2012)
    respect to nominations, this recess closely resembles one of substantially
    greater length.” 
    Id.
     To be sure, this Office there stated only that two
    recesses broken solely by a pro forma session “closely resemble[]” a
    single recess of greater length, not that they were constitutionally indis-
    tinguishable from one. Nevertheless, we thought the effective length of the
    recess relevant in determining whether the President could make a recess
    appointment. The same consideration applies here. A lengthy intrasession
    recess broken only by pro forma sessions closely resembles an unbroken
    recess of the same length; thus, “[e]xcept for its brief formal session[s]
    . . . the Senate will have been absent from [January 3, 2012] until [January
    23, 2012], a period of [twenty] days.” 
    Id.
     And in determining whether
    such a recess triggers the President’s appointment authority under the
    Recess Appointments Clause, we believe the critical inquiry is the “prac-
    tical” one identified above—to wit, whether the Senate is available to
    perform its advise-and-consent function. For practical purposes, the
    President may properly view the Senate as unavailable for twenty days.
    Second, allowing the Senate to prevent the President from exercising
    his authority under the Recess Appointments Clause by holding pro forma
    sessions would be inconsistent with both the purpose of the Clause and
    historical practice in analogous situations. As explained above, the Recess
    Appointments Clause has long been understood as intended to provide a
    method of appointment when the Senate was unavailable to provide
    advice and consent, so that offices would not remain vacant to the detri-
    ment of the public interest. If the Senate can avoid a “Recess of the Sen-
    ate” under the Clause by having a single Member “gavel in” before an
    empty chamber, then the Senate can preclude the President from making
    recess appointments even when, as a practical matter, it is unavailable to
    fulfill its constitutional role in the appointment process for a significant
    period of time. The purpose of the Clause is better served by a construc-
    tion that permits the President to make recess appointments when the
    Senate is unavailable to advise and consent for lengthy periods. See Pow-
    er of President to Fill Vacancies, 2 Op. Att’y Gen. 525, 526–27 (1832)
    (“[A] construction that defeats the very object of the grant of power
    cannot be the true one. It was the intention of the constitution that the
    offices created by law, and necessary to carry on the operations of the
    government, should always be full, or, at all events, that the vacancy
    should not be a protracted one.”); cf. Wright v. United States, 
    302 U.S. 36
    Recess Appointments Amid Pro Forma Senate Sessions
    583, 596 (1938) (“We should not adopt a construction [of the Veto Claus-
    es] which would frustrate either of the[ir] purposes.”).
    Further, Presidents have routinely exercised their constitutional authori-
    ty to make recess appointments between sessions of Congress since Presi-
    dent Washington made such appointments in the earliest days of the
    Republic. Although we have focused in this opinion on the twenty-day
    intrasession recess at the beginning of the second session, the Senate in
    fact adjourned pursuant to an order that provided that there would also be
    “no business conducted” for the final seventeen days of the first session.
    This period of time, a total of thirty-seven days, in substance closely
    resembles a lengthy intersession recess. See Recess Appointments During
    an Intrasession Recess, 16 Op. O.L.C. at 15 n.1. Thus, an understanding
    of the Recess Appointments Clause that permits the President to make
    appointments during this recess also would be consistent with historical
    practice.
    Third, permitting the Senate to prevent the President from making re-
    cess appointments through pro forma sessions would raise constitutional
    separation of powers concerns. To preserve the constitutional balance of
    powers, the Supreme Court has held that congressional action is invalid if
    it “‘undermine[s]’ the powers of the Executive Branch, or ‘disrupts the
    proper balance between the coordinate branches [by] prevent[ing] the
    Executive Branch from accomplishing its constitutionally assigned func-
    tions.’” Morrison v. Olson, 
    487 U.S. 654
    , 695 (1988) (quoting Commodity
    Futures Trading Comm’n v. Schor, 
    478 U.S. 833
    , 856 (1986); Nixon v.
    Adm’r of Gen. Servs., 
    433 U.S. 425
    , 443 (1977) (alterations in Morri-
    son)); accord Loving v. United States, 
    517 U.S. 748
    , 757 (1996) (“[I]t
    remains a basic principle of our constitutional scheme that one branch of
    the Government may not intrude upon the central prerogatives of another.
    Even when a branch does not arrogate power to itself . . . the separation-
    of-powers doctrine requires that a branch not impair another in the per-
    formance of its constitutional duties.” (citations omitted)).
    The Constitution expressly confers upon the President the power to
    make recess appointments when the Senate is unable to give its advice
    and consent because it is in recess. It is the established view of the Execu-
    tive Branch that
    Congress may not derogate from the President’s constitutional au-
    thority to fill up vacancies during recesses, by granting less power to
    37

     (2012)
    a recess appointee than a Senate-confirmed occupant of the office
    would exercise: “Provisions purporting to grant authority only to in-
    dividuals confirmed by the Senate interfere with the President’s re-
    cess appointment power, and are unconstitutional.”

    There is also some judicial authority recognizing the need to protect the
    President’s recess appointment authority from congressional incursion.

    the Pay Act, 5 U.S.C. § 5503 (2006), which imposes certain restrictions on the payment of
    recess appointees. See Memorandum for the Attorney General, from John O. McGinnis,
    Deputy Assistant Attorney General, Office of Legal Counsel, Re: Recess Appointments
    at 7 n.7 (July 7, 1988) (“Because it places limitations on the President’s exercise of his
    constitutional authority, 5 U.S.C. § 5503 may be unconstitutional.”); Intrasession Recess

    ments.”). The Senate’s use of pro forma sessions to prevent the President from making
    recess appointments, if valid, would constitute a greater restriction on recess appointment
    authority than the terms of the Pay Act. The latter allows payment of recess appointees
    under a number of circumstances and permits retroactive payment after a person serving

    We recognize that the Senate may choose to remain continuously in
    session and available to exercise its advise-and-consent function and
    thereby prevent the President from making recess appointments. But,
    under the legal authority set forth above, the President may properly
    determine that the Senate is not available under the Recess Appointments
    Clause when, while in recess, it holds pro forma sessions where no busi-
    ness can be conducted. Such sessions do not have the legal effect of
    interrupting a Senate recess for purposes of the Recess Appointments
    Clause.
    3.
    We have considered several counterarguments to our analysis. In our
    judgment, these points, while not insubstantial, do not overcome the
    conclusion presented above.
    First, we considered that the Senate has employed pro forma sessions
    in other contexts and that, in those contexts, a pro forma session may
    have the same legal effect as any other session and thus may fulfill cer-
    tain constitutional requirements. For example, pro forma sessions are
    most commonly used to address the requirement that “[n]either House,
    during the Session of Congress, shall, without the Consent of the other,
    adjourn for more than three days.” U.S. Const. art. I, § 5, cl. 4; see U.S.
    Senate Glossary, http://www.senate.gov/reference/glossary_term/pro_
    forma_session.htm (last visited ca. Jan. 2012) (defining “pro forma
    session” as a “brief meeting (sometimes only several seconds) of the
    Senate in which no business is conducted”; “[i]t is held usually to satisfy
    40
    Recess Appointments Amid Pro Forma Senate Sessions
    the constitutional obligation that neither chamber can adjourn for more
    than three days without the consent of the other”). 21 In addition, in 1980,
    and sporadically thereafter, pro forma sessions have been used to address
    the Twentieth Amendment’s direction that, in the absence of legislation
    providing otherwise, Congress must convene on January 3. 22 Pro forma
    sessions have also been employed for parliamentary purposes, e.g., to
    permit a cloture vote to ripen, or to hear an address. 23
    Those precedents provide only weak support for the claim that a series
    of consecutive pro forma sessions may be used to block recess appoint-
    ments in the circumstances presented here. There is no evidence of a
    21 Riddick’s Senate Procedure identifies several examples in which “the Senate pursu-
    ant to a previous order has met for very brief periods and recessed over until a subsequent
    date, not in excess of 3 days,” the earliest of which occurred in 1949. Id. at 251 & nn.1–3.
    22 U.S. Const. amend. XX, § 2 (“Congress shall assemble at least once in every year,
    and such meeting shall begin at noon on the 3d day of January, unless they shall by law
    appoint a different day.”). Congress routinely enacts legislation when it wishes to vary the
    date of its first meeting. See, e.g., Pub. L. No. 111-289 (2010); Pub. L. No. 105-350
    (1998); Pub. L. No. 99-613 (1986); Pub. L. No. 94-494 (1978); Pub. L. No. 89-340
    (1965); Pub. L. No. 83-199 (1953); Pub. L. No. 79-289 (1945). Occasionally, however,
    Congress (or an individual House) uses a pro forma session to comply with the Twentieth
    Amendment’s default date. The first such use of a pro forma session that we are aware of
    occurred in 1980. See H.R. Con. Res. 232, 96th Cong., 93 Stat. 1438 (1979) (“[W]hen the
    Congress convenes on January 3, 1980, . . . neither the House nor the Senate shall conduct
    organizational or legislative business until Tuesday, January 22, 1980, [unless convened
    sooner by House and Senate leaders].”). Thereafter, it appears to have remained rare until
    the last decade. See H.R. Con. Res. 260, 102d Cong., 105 Stat. 2446 (1991) (providing
    that neither House shall “conduct organizational or legislative business” on January 3,
    1992); 151 Cong. Rec. S14,421 (daily ed. Dec. 21, 2005) (Senate order providing for “a
    pro forma session only” on January 3, 2006”); 153 Cong. Rec. S16,069 (daily ed. Dec. 19,
    2007) (same for January 3, 2008); 157 Cong. Rec. S8783 (daily ed. Dec. 17, 2011) (same
    for January 3, 3012). On at least one occasion, Congress has changed the date of the first
    meeting of a session by law and both Houses held pro forma sessions to comply with that
    law. See Pub. L. No. 111-121, 123 Stat. 3479 (2009) (providing that the second session of
    the 111th Congress begin on January 5, 2010); 155 Cong. Rec. S14,140 (daily ed. Dec.
    24, 2009) (Senate order providing for “a pro forma session only” on January 5, 2010); 156
    Cong. Rec. H2–H8 (daily ed. Jan. 5, 2010) (“[N]o organizational or legislative business
    will be conducted on this day.”).
    23 See 133 Cong. Rec. 15,445 (1987) (“The Senate will go over until Monday pro for-
    ma, no business, no speeches, just in and out, and the pro forma meeting on Monday
    would qualify the cloture motion to be voted on Tuesday[.]”); 139 Cong. Rec. 3039, 3039
    (1993) (“Any sessions will be pro forma or solely for the purpose of hearing the Presi-
    dents’ Day address on Wednesday morning.”).

    tradition of using pro forma sessions to prevent a “recess” within the
    meaning of the Recess Appointments Clause. That attempt began in 2007
    with the 110th Congress. 24 There may be at least a limited tradition of a
    House of Congress using consecutive pro forma sessions to avoid ad-
    journments of more than three days without obtaining the other House’s
    consent. 25 But past uses of pro forma sessions for housekeeping purposes
    are not good analogies for the current use of pro forma sessions to block
    appointments under the Recess Appointments Clause. The former uses
    affect the operations of only the House in question, and the Constitution
    provides that “[e]ach House may determine the Rules of its Proceedings,”
    U.S. Const. art. I, § 5, cl. 2. Even uses in connection with interchamber
    relations affect the Legislative Branch alone. The question whether the
    24 It does appear, though, that the use of pro forma sessions to prevent recess appoint-
    ments was at least contemplated as early as the 1980s. See 145 Cong. Rec. 29,915 (1999)
    (statement of Sen. Inhofe) (“[Senator Byrd] extracted from [the President] a commitment
    in writing that he would not make recess appointments and, if it should become necessary
    because of extraordinary circumstances to make recess appointments, that he would give
    the list to the majority leader . . . in sufficient time in advance that they could prepare for
    it either by agreeing in advance to the confirmation of that appointment or by not going
    into recess and staying in pro forma so the recess appointments could not take place.”).
    25 For example, in 1929, a concurrent resolution provided that the House return from
    summer recess on September 23, 71 Cong. Rec. 3045 (June 18, 1929). The House passed
    a separate resolution providing that “after September 23, 1929, the House shall meet only
    on Mondays and Thursdays of each week until October 14, 1929,” provided that the
    Speaker could call them back sooner if “legislative expediency shall warrant it,” id. at
    3228 (June 19, 1929). Although it was not so stated in the text of the resolution, it was
    “agreed that there shall be nothing transacted [during the Monday and Thursday sessions]
    except to convene and adjourn; no business whatever.” Id. at 3229 (statement of Rep.
    Tilson); see also 8 Cannon’s Precedents of the House of Representatives § 3369, at 820
    (1935) (describing this incident as one in which the House “provid[ed] for merely formal
    sessions”). This arrangement was subsequently extended twice. 71 Cong. Rec. 4531–32
    (Oct. 14, 1929) (H.R. Res. 59, described by Rep. Tilson as “the same resolution, the dates
    being changed, as the original recess resolution passed by the House last June); id. at
    5422 (Nov. 11, 1929). Subsequent examples from the Senate involve more formal agree-
    ments to the pro forma nature of the sessions. See, e.g., 96 Cong. Rec. 16,980 (Dec. 22,
    1950) (setting schedule of two consecutive pro forma sessions); id. at 17,020 (Dec. 26,
    1950); id. at 17,022 (Dec. 29, 1950); 126 Cong. Rec. 2574 (Feb. 8, 1980) (setting sched-
    ule of two consecutive pro forma sessions); id. at 2614 (Feb. 11, 1980); id. at 2853 (Feb.
    14, 1980); 127 Cong. Rec. 190 (Jan. 6, 1981) (setting schedule of three consecutive pro
    forma sessions); id. at 238 (Jan. 8, 1981); id. at 263 (Jan. 12, 1981); id. at 276 (Jan. 15,
    1981).

    Recess Appointments Amid Pro Forma Senate Sessions
    use of pro forma sessions for those purposes is consistent with the Consti-
    tution is not presented here. Assuming that such uses are constitutional,
    however, it does not follow that pro forma sessions may be used to pre-
    vent the President from exercising his constitutional authority to make
    recess appointments when he determines that the Senate is unavailable to
    provide advice and consent. 26 Put differently, whether the House has
    consented to the Senate’s adjournment of more than three days does not
    determine the Senate’s practical availability during a period of pro forma
    sessions and thus does not determine the existence of a “Recess” under
    the Recess Appointments Clause.
    Second, it might be argued that, in light of the Senate’s power to “de-
    termine the Rules of its Proceedings,” U.S. Const. art. I, § 5, cl. 2, the
    Executive Branch would be bound by the Chamber’s own understanding
    of whether the pro forma sessions have the legal effect of interrupting a
    “Recess of the Senate” for the purposes of the Recess Appointments
    Clause. The Rules of Proceedings Clause has been understood to grant the
    Houses of Congress broad discretion in managing their internal affairs.
    See, e.g., United States v. Ballin, 
    144 U.S. 1
    , 5 (1892) (“[A]ll matters of
    method [of proceeding] are open to the determination of the house, and it
    is no impeachment of the rule to say that some other way would be better,
    more accurate or even more just.”). That Clause might also be understood
    to permit them conclusively to determine when they are in session and
    when they are in recess. See, e.g., Michael Herz, Abandoning Recess
    Appointments?: A Comment on Hartnett (and Others), 26 Cardozo L.
    Rev. 443, 459 (2005) (“I would think that pursuant to the authority of
    each House to make rules for its own proceedings Congress could decide
    to hold twelve ‘sessions’ each calendar year, with a few days off—
    perhaps just a weekend—between them.”); cf. Arthur S. Miller, Congres-
    sional Power to Define the Presidential Pocket Veto Power, 25 Vand. L.
    26 Cf. Letter for Peter W. Rodino, Jr., Chairman, Committee on the Judiciary, U.S.
    House of Representatives, from Robert G. Dixon, Assistant Attorney General, Office of
    Legal Counsel at 4 –5 (Dec. 4, 1973) (“Under Section 2 of H.R. 7386, Congress could
    prevent the exercise of a pocket veto, except at the close of a Congress, when one or both
    Houses adjourned for several months, by adjourning either to a date certain or pro forma
    to a date close to the beginning of the next working session. . . . To the extent that H.R.
    7386 unconstitutionally permits Congress to keep a bill in suspended animation for
    lengthy periods during adjournments other than sine die, it unconstitutionally narrows the
    President’s pocket veto authority.”).
    43
    
    36 Op. O.L.C. 15
     (2012)
    Rev. 557, 567 (1972) (“Surely the determination of what constitutes
    adjournment is a ‘proceeding’ within the terms of that section [the
    Rules of Proceeding Clause].”).
    The Supreme Court, however, has made clear that Congress’s power
    under this provision is not unlimited, and specifically that Congress “may
    not by its rules ignore constitutional restraints or violate fundamental
    rights.” Ballin, 
    144 U.S. at 5
    . Thus, the validity and application of con-
    gressional rules are subject to review in court when the rules affect inter-
    ests outside of the Legislative Branch. See, e.g., United States v. Smith,
    
    286 U.S. 6
    , 33 (1932) (“As the construction to be given the rules affects
    persons other than members of the Senate, the question presented is of
    necessity a judicial one.”); Ballin, 
    144 U.S. at 5
     (“[T]here should be a
    reasonable relation between the mode or method of proceeding estab-
    lished by the rule and the result which is sought to be attained.”); Vander
    Jagt v. O’Neill, 
    699 F.2d 1166
    , 1173 (D.C. Cir. 1983) (“Article I does not
    alter our judicial responsibility to say what rules Congress may not adopt
    because of constitutional infirmity.”). A Senate rule that pro forma ses-
    sions interrupt a “Recess of the Senate” (or that otherwise seeks to pre-
    vent the President from exercising authority under the Recess Appoint-
    ments Clause) would affect other persons—the President and potential
    appointees at the least. It would also disrupt the Constitution’s balancing
    of executive and legislative authority in the appointments process. To be
    sure, as explained above, the President’s authority to make recess ap-
    pointments is constrained when the Senate is continuously in session and
    available to perform its advise-and-consent function. But the Senate could
    not by rule unilaterally prevent the President from exercising his authority
    to make temporary appointments under the Clause by declaring itself in
    session when, in practice, it is not available to provide advice and con-
    sent, any more than the President could make a recess appointment when
    the Senate was in practice available to do so. See Daugherty Opinion, 33
    Op. Att’y Gen. at 25 (recognizing that a “palpable abuse” of the Presi-
    dent’s “discretion to determine when there is a real and genuine recess” of
    the Senate might subject his appointment to review”). 27
    27The Senate’s scheduling of pro forma sessions to frustrate the President’s recess
    appointment authority does not require us to treat the President’s constitutional recess
    appointment authority as operating at the “lowest ebb” of presidential power under the
    framework of Justice Jackson’s concurring opinion in Youngstown Sheet & Tube Co. v.
    44
    Recess Appointments Amid Pro Forma Senate Sessions
    Third, it could be argued that the experience of recent pro forma ses-
    sions suggests that the Senate is in fact available to fulfill its constitution-
    al duties during recesses punctuated by periodic pro forma sessions.
    Twice in 2011, the Senate passed legislation during pro forma sessions by
    unanimous consent, evidenced by the lack of objection from any member
    who might have been present at the time. 157 Cong. Rec. S8789 (daily ed.
    Dec. 23, 2011); 
    id.
     at S5297 (daily ed. Aug. 5, 2011). During one of these
    sessions, the Senate also agreed to a conference with the House, and
    messages received from the House earlier in the intrasession recess were
    put into the Congressional Record. 157 Cong. Rec. S8789–90 (daily ed.
    Dec. 23, 2011). Conceivably, the Senate might provide advice and con-
    sent on pending nominations during a pro forma session in the same
    manner.
    We do not believe, however, that these examples prevent the President
    from determining that the Senate remains unavailable to provide advice
    and consent during the present intrasession recess. The scheduling order
    under which the pro forma sessions are held during this recess expressly
    provides that there is to be “no business conducted.” 157 Cong. Rec.
    S8783 (daily ed. Dec. 17, 2001). In our judgment, the President may
    properly rely on the public pronouncements of the Senate that it will not
    conduct business (including action on nominations), in determining
    whether the Senate remains in recess, regardless of whether the Senate has
    disregarded its own orders on prior occasions. Moreover, even absent a
    Senate pronouncement that it will not conduct business, there may be
    circumstances in which the President could properly conclude that the
    body is not available to provide advice and consent for a sufficient period
    to support the use of his recess appointment power. It is common for
    Sawyer, 
    343 U.S. 579
    , 637 (1952). The Constitution explicitly grants recess appointment
    authority to the President, and the Attorney General has long taken the position that,
    through enactment of the Pay Act, Congress has “acquiesce[d]” to recess appointments
    under circumstances where that Act would permit payment. See Recess Appointments, 41
    Op. Att’y Gen. at 466; see also Appointments—Recess Appointments, 28 Comp. Gen. at
    34, 37 (recognizing the “accepted view” that an extended intrasession adjournment of the
    Senate is a “recess” in the constitutional sense during which “an appointment properly
    may be made” and that recipients of such appointments were entitled to pay). Moreover, it
    is unclear that Justice Jackson’s framework would apply in matters involving the balance
    between the President’s constitutional authority to make recess appointments and a single
    House of Congress’s constitutional authority to set its internal rules.
    45
    
    36 Op. O.L.C. 15
     (2012)
    resolutions of adjournment authorizing extended intrasession recesses to
    provide that the Senate “stand[s] recessed or adjourned until [a specified
    date], . . . or until the time of any reassembly” ordered by the leaders of
    the two Houses “as they may designate whenever, in their opinion, the
    public interest shall warrant it.” See, e.g., H.R. Con. Res. 361, 108th
    Cong. (2004). That potential for reassembly by itself does not deprive an
    extended Senate absence of its character as a recess. In fact, the Senate
    had adjourned pursuant to such a resolution before the intrasession recess
    during which Judge Pryor was appointed to the Eleventh Circuit. That
    recess appointment was approved by this Office, see Goldsmith Memo-
    randum, and upheld by the court of appeals en banc, see Evans v. Ste-
    phens, 
    387 F.3d 1220
    .
    Fourth, legal precedent addressing the President’s authority to pocket
    veto during a recess a bill passed by Congress conceivably might be
    viewed as constraining the President’s recess appointment authority in the
    current recess. For example, in Wright v. United States, 
    302 U.S. 583
    , the
    Supreme Court held that a temporary adjournment of the Senate (for
    which consent of the House was not required under Article I, Section 5,
    Clause 4 of the Constitution) did not prevent the President from vetoing a
    bill. And in Kennedy v. Sampson, 
    511 F.2d 430
     (D.C. Cir. 1974), the D.C.
    Circuit extended Wright to reach all intrasession adjournments, provided
    that arrangements were made for the receipt of presidential messages. 28 It
    could be argued that these cases either delineate the types of Senate ad-
    journments that are insufficient to qualify as a “Recess of the Senate”
    under the Recess Appointments Clause, or establish that the Senate can
    take some action short of actually remaining in session to mitigate the
    consequences of its absence.
    We have previously observed that “[w]hile the Pocket Veto and Recess
    Appointments Clauses deal with similar situations, that is, the President’s
    powers while Congress or the Senate is not in session, their language, ef-
    fects, and purposes are by no means identical.” Recess Appointments Issues,
    
    6 Op. O.L.C. 585
    , 589 (1982). And “[i]n light of the[se] differen[ces] . . . we
    do not believe [that Sampson] should be read as having any significant
    28 In Barnes v. Kline, 
    759 F.2d 21
    , 41 (D.C. Cir. 1985), the court held that the Presi-
    dent is not “prevent[ed]” from returning a bill even during an intersession recess if a duly
    authorized officer of the originating house is available to receive it. That decision was
    later vacated as moot. See Burke v. Barnes, 
    479 U.S. 361
     (1987).
    46
    Recess Appointments Amid Pro Forma Senate Sessions
    bearing on the proper interpretation of the Recess Appointments Clause.” 
    Id. at 590
    . Moreover, we have concluded that “there are sound reasons to be-
    lieve that the President has authority to make recess appointments in situa-
    tions in which a pocket veto might well be inappropriate.” The Pocket Veto:
    Historical Practice and Judicial Precedent, 
    6 Op. O.L.C. 134
    , 149 (1982).
    The Pocket Veto Clause “ensures that the President will not be de-
    prived of his constitutional power to veto a bill by reason of an adjourn-
    ment.” Recess Appointments Issues, 6 Op. O.L.C. at 590. The holdings in
    Wright and Sampson—that the President could not pocket veto a bill
    during an intrasession recess where the Senate had designated an agent to
    receive the return of a bill—were “bottomed on the theory that [the ad-
    journments at issue] did not ‘prevent’ the return of disapproved bills.” The
    Pocket Veto, 6 Op. O.L.C. at 149. Put another way, the designation of an
    agent to receive messages and the pocket veto serve the same purpose,
    i.e., protecting the President’s right to disapprove bills, and therefore
    obviate the need for the power provided by the Clause.
    The Recess Appointments Clause, however, serves a different purpose. It
    “enables the President to fill vacancies which exist while the Senate is
    unable to give its advice and consent because it is in recess.” Recess Ap-
    pointments Issues, 6 Op. O.L.C. at 590. The designation of an agent to
    receive messages neither allows the President to fill vacancies nor makes the
    Senate available to advise and consent. Thus, the President’s ability to make
    appointments during a recess is necessary to further the Recess Appoint-
    ments Clause’s purpose, while the President’s authority to pocket veto
    arguably is not necessary when the presence of a congressional agent allows
    him to return a bill, exercising his constitutional prerogative to disapprove
    legislation. While the congressional designation of an agent arguably ad-
    dresses the constitutional concerns embodied in the President’s pocket veto
    authority, the periodic convening of pro forma sessions at which no business
    is to be conducted simply does not address the constitutional concerns
    arising from the Senate’s unavailability to consider appointments.
    Finally, we considered whether the Department of Justice has already tak-
    en a different view. In arguing that the recess appointment of a member of
    the National Labor Relations Board (“NLRB”) did not render moot the
    controversy about legal consequences of the absence of a Board quorum, the
    Solicitor General said that “the Senate may act to foreclose [recess appoint-
    ments] by declining to recess for more than two or three days at a time over
    47
    
    36 Op. O.L.C. 15
     (2012)
    a lengthy period,” using the Senate’s 2007 pro forma sessions as an exam-
    ple. Letter for William K. Suter, Clerk, Supreme Court of the United States,
    from Elena Kagan, Solicitor General, Office of the Solicitor General, at 3
    (April 26, 2010), New Process Steel, L.P. v. NLRB, 
    130 S. Ct. 2635
     (2010)
    (No. 08-1457). This portion of the letter is focused on the question whether
    an intrasession recess of three days or fewer constitutes a recess under the
    Recess Appointments Clause. See 
    id.
     (“[T]he Senate did not recess intra-
    session for more than three days at a time for over a year beginning in late
    2007.”); 
    id. at 3 n.2
     (“[O]fficial congressional documents define a ‘recess’ as
    ‘any period of three or more complete days . . . when either the House of
    Representatives or the Senate is not in session.’” (quoting 2003–2004 Con-
    gressional Directory 526 n.2 (Joint Comm. on Printing, 108th Cong., comp.
    2003)). The letter (like this opinion, see supra note 13) does not answer that
    question. Instead, the letter uses the uncertain status of recess appointments
    during intrasession recesses of three or fewer days to argue that the possibil-
    ity of recess appointments did not render New Process Steel moot. Thus, it
    does not answer the question addressed here, whether pro forma sessions at
    which no business is conducted interrupt a recess that is more than three
    days long in a manner that would preclude the President from exercising his
    appointment power under the Clause.
    III.
    In our judgment, the text of the Constitution and precedent and practice
    thereunder support the conclusion that the convening of periodic pro
    forma sessions in which no business is to be conducted does not have the
    legal effect of interrupting an intrasession recess otherwise long enough to
    qualify as a “Recess of the Senate” under the Recess Appointments
    Clause. In this context, the President therefore has discretion to conclude
    that the Senate is unavailable to perform its advise-and-consent function
    and to exercise his power to make recess appointments.
