    This memorandum memorializes and explains advice we provided to you in
    May of 1999 regarding whether Pub. L. No. 106-31, 
    113 Stat. 57
     (May 21, 1999),
    the emergency supplemental appropriation for military operations in Kosovo, con­
    stituted authorization for continuing hostilities after the expiration of sixty days
    under section 5(b) of the War Powers Resolution, Pub. L. No. 93-148, 
    87 Stat. 555
     (1973) (codified at 
    50 U.S.C. §§ 1541-1548
     (1994)) (the “ WPR” ). This
    Office advised that the appropriation did constitute such authorization. Subse­
    quently, the district court for the District of Columbia and the Court o f Appeals
    for the D.C. Circuit decided a lawsuit brought against the President by thirty-
    one members of Congress, who claimed that the President had violated the Con­
    stitution and the WPR by involving the United States in hostilities in Kosovo
    without congressional authorization. Neither the district court nor the court of
    appeals reached the merits of the plaintiffs’ claims. The district court dismissed
    the suit for lack of standing, Campbell v. Clinton, 
    52 F. Supp. 2d 34
     (D.D.C.
    1999), and the D.C. Circuit affirmed the dismissal, also on standing grounds, 
    203 F.3d 19
     (D.C. Cir.), cert, denied, 
    531 U.S. 815
     (2000).
    Section I o f this memorandum summarizes the relevant provisions of the WPR,
    including section 8(a)(1), which provides that authorization may not be inferred
    from appropriation laws that do not specifically refer back to the WPR. Section
    II shows that the relevant case law, historical practice, and basic principles of
    constitutional law lead to the conclusion that appropriation laws may authorize
    military combat. Section III shows that section 8(a)(1) does not bar later Con­
    gresses from authorizing military operations through appropriations (an interpreta­
    tion that would be unconstitutional), but instead has the effect of creating a back­
    ground principle that may inform the interpretation of later Acts of Congress.
    Section IV shows that by enacting Pub. L. No. 106-31, Congress intended to
    enable the President to continue U.S. participation in Operation Allied Force.
    Finally, Section V presents this Office’s conclusion that, even taking account of
    the background principle established by section 8(a)(1), Pub. L. No. 106-31
    authorized the President to continue military operations in Kosovo.1
    1Previous Administrations have expressed different views concerning the constitutionality of the W PR. Compare

    I. The War Powers Resolution and Authorization o f Hostilities
    The W PR is framework legislation that sets forth procedures for reporting and
    authorizing hostilities. The statute begins with a congressional declaration of pur­
    pose:
    It is the purpose of this chapter to fulfill the intent of the framers
    of the Constitution of the United States and insure that the collec­
    tive judgment of both the Congress and the President will apply
    to the introduction of United States Armed Forces into hostilities,
    or into situations where imminent involvement in hostilities is
    clearly indicated by the circumstances, and to the continued use
    of such forces in hostilities o r in such situations.
    
    50 U.S.C. § 1541
    (a).2 This section summarizes the most important provisions of
    the statute.
    The “ core” of the WPR “ resides in sections 4(a)(1) and 5(b).” John Hart Ely,
    War and R esponsibility 48 (1993).3 Section 4(a)(1) of the WPR requires the Presi­
    dent to submit a report to Congress whenever, “ [i]n the absence of a declaration
    of w ar,” United States Armed Forces are introduced “ into hostilities or into situa­
    tions where imminent involvement in hostilities is clearly indicated by the cir­
    cumstances.” 
    50 U.S.C. § 1543
    (a)(1). Section 5(b) requires the President to
    “ terminate any use o f the United States Armed Forces with respect to which [a]
    report [under section 4(a)(1)] was submitted (or required) [within 60 days there­
    after]” unless the Congress takes certain enumerated actions to authorize con­
    tinuing combat or “ is physically unable to meet as a result of an armed attack
    upon the United States.” 
    50 U.S.C. § 1544
    (b). The 60 day period may be extended
    the provision in the W PR that “ would automatically cut off certain authorities after sixty days unless the Congress
    extended them ” ), with “ Ask President Carter” . Rem arks Dunng a Telephone Call — in Program on the CBS Radio
    Network,” 1 Pub Papers o f Jimmy Carter 324 (M ar 5, 1977) (noting that W PR is an “ appropriate reduction”
    in the President’s power), Presidential Power to U se the Arm ed Forces Abroad Without Statutory Authorization,
    4 A Op. O.L.C. 185, 196 (1980) ( “ We believe that Congress may, as a general constitutional matter, place a 60-
    day limit on the use o f our armed forces as required by the provisions of § 1544(b) of the Resolution ” ). In light
    of our conclusion that Congress lawfully authonzed continued hostilities beyond the 60-day statutory limit, we have
    no occasion to consider any constitutional arguments that might be made.
    2The W PR had its origins in the Vietnam War. See 119 Cong. Rec. 1394 (1973) (statement of Senator Javits)
    ( “ [WPR was] an effort to leam from the lessons o f the last tragic decade of war in Vietnam which has cost our
    Nation so heavily in blood, treasure, and morale. T he War Powers Act would assure that any future decision to
    commit the U nited States to any warmaking must be shared in by the Congress to be lawful ” ); see also Thomas
    F. Eagleton, War and Presidential Power 107-123 (1974) (discussing background of WPR in Vietnam War). For
    discussion o f initial attempts to enact war powers legislation, see Thomas F. Eagleton, Congress and the War Powers,
    37 Mo. L. Rev 1, 18-20 (1972); W illiam B. Spong. Jr., Can Balance Be Restored in the Constitutional War Powers
    o f the President and C ongress7, 6 U Rich L Rev 1, 18-28 (1971). Senator Eagleton introduced a war powers
    bill into the Senate in 1971 and played a prominent role in the Senate debates over war powers legislation Senator
    Spong, in conjunction with Senators Javits and Eagleton, managed the Senate War Powers legislation for the Foreign
    Relations Com m ittee See Eagleton, supra, at 134

    Authorization fo r Continuing Hostilities in Kosovo
    for an additional 30 days if the President certifies to Congress that “ unavoidable
    military necessity respecting the safety of United States Armed Forces requires
    the continued use of such armed forces in bringing about a prompt removal of
    such forces.” Id. Thus, when a report under section 4(a)(1) is filed (or required
    to be filed), section 5(b)’s 60 day (or, in appropriate circumstances, 90 day)
    “ clock” begins to run.4
    Under section 5(b), Congress may, within the 60 day period, authorize con­
    tinuing hostilities after that period by any one of three methods: (1) by a declara­
    tion of war; (2) by enacting a “ specific authorization for such use of United States
    Armed forces” ; or (3) by “ extend[ing] by law such sixty-day period.” 
    50 U.S.C. § 1544
    (b). The section thus functions essentially as a burden-shifting device. As
    Judge Joyce Hens Green has observed:
    [T]he automatic cutoff after 60 days was intended to place the bur­
    den on the President to seek positive approval from the Congress,
    rather than to require the Congress positively to disapprove the
    action, which had proven so politically difficult during the Vietnam
    war. To give force to congressional power to declare war, Presi­
    dential warmaking would not be justified by congressional silence,
    but only by a congressional initiative . . . .

    , 899 (D.D.C. 1982), o ffd , 
    720 F.2d 1355
    (D.C. Cir. 1983).5 In addition to requiring the President to seek approval for con­
    tinuing hostilities, section 5(b) is also designed to hold Congress responsible for
    the ultimate decision over war and peace.6
    4 The full text of section 5(b) reads as follows1
    Within sixty calendar days after a report is submitted or is required to be submitted pursuant to section
    1543(a)(1) of this title, whichever is earlier, the President shall terminate any use of United States Armed
    Forces with respect to which such report was submitted (or required to be submitted), unless the Congress
    (1) has declared war or has enacted a specific authorization for such use of United States Armed Forces,
    (2) has extended by law such sixty-day penod, or (3) is physically unable to meet as a result of an armed
    attack upon the United States Such sixty-day penod shall be extended for not more than an additional
    thirty days if the President determines and certifies to the Congress in w nting that unavoidable military
    necessity respecting the safety o f United States Armed Forces requires the continued use of such armed
    forces in the course o f bnnging about a prompt removal o f such forces

    Opinions o f the Office o f Legal Counsel in Volume 24
    By its terms, the statute contemplates possible mechanisms for authorizing hos­
    tilities other than a declaration of war. The decision as to which legal vehicle
    to choose is within Congress’s power: it is well established that “ it is constitu­
    tionally permissible for Congress to use another means than a formal declaration
    of war to give its approval to a w ar.” Mitchell v. Laird, 
    488 F.2d 611

    recall no instance where Congress has made a formal declaration of war against
    an Indian nation or tribe; but the fact that Indians are engaged in acts of general
    hostility to settlers, especially if the government has deemed it necessary to des­
    patch a military force for their subjugation, is sufficient to constitute a state of
    war.” ); Berk v. Laird,

    it chooses to record that assent is within its discretion to decide.” ). Moreover,
    in the period since the WPR was enacted, Congress has explicitly authorized hos­
    tilities under the statute without declaring war.7 Congress has in fact often author­
    ized hostilities by legislative measures other than formal “ declarations of war”
    since the days of the early republic.8 Indeed, at the time of the Founding, formal

    so,” Castillo, 34 M.J. at 1164; nonetheless, it unquestionably (and in terms) provided specific statutory authorization
    within the meaning o f section 5(b) for the conflict that ensued, see note at § 2(c)(1) ( “ Consistent with section 8(a)(1)
    of the W ar Powers Resolution, the Congress declares that this section is intended to constitute specific statutory

    following 50 U S.C. § 1541, expressly authonzed the continued presence o f United States Armed Forces in Lebanon
    for 18 months following the date o f the statute’s enactment and did not involve a declaration of war See id. §2(c)
    (“ The Congress intends this joint resolution lo constitute the necessary specific statutory authorization under the

    “ declarations” of war were increasingly rare in state practice,9 and prominent

    9Thus, when France in 1778 entered the Revolutionary War as an ally of the Colonies against Great Bntain,
    it did not issue a “ Declaration of W ar” — although it did so in June, 1779 See Samuel Flagg Bemis, The Diplomacy

    Opinions o f the Office o f Legal Counsel in Volume 24
    (1) from any provision of law . . . including any provision con­
    tained in any appropriations Act, unless such provision specifically
    authorizes the introduction o f United States Armed Forces into hos­
    tilities or into such situations and states that it is intended to con­
    stitute specific statutory authorization within the meaning of this
    chapter.
    
    50 U.S.C. § 1547
    (a)(1).
    Like section 5(b), section 8(a) implicitly recognizes that Congress may authorize
    hostilities by means other than a declaration of war. Because it purports to allow
    Congress to authorize hostilities through appropriation statutes that specifically
    invoke the WPR, section 8(a) further recognizes that appropriation statutes may,
    under some circumstances, authorize hostilities.
    II. Appropriations and Authorization o f M ilitary Combat
    The Supreme Court has recognized that, as a general matter, appropriation stat­
    utes may “ stand[] as confirmation and ratification of the action of the Chief
    Executive.” Fleming v. Mohawk Wrecking & Lumber Co., 331 U.S. I l l , 116
    (1947). Congress may also “ amend substantive law in an appropriations statute,
    as long as it does so clearly.” Robertson v. Seattle Audubon Soc., 
    503 U.S. 429
    ,
    440 (1992). “ [W]hen Congress desires to suspend or repeal a statute in force,
    ‘[t]here can be no doubt that . . . it could accomplish its purpose by an amend­
    ment to an appropriation bill, or otherwise.’ United States v. Dickerson, 
    310 U.S. 554
    , 555 (1940). ‘The whole question depends on the intent of Congress as
    expressed in the statutes.’ United States v. Mitchell, 
    109 U.S. 146
    , 150 (1883).”
    United States v. Will, 
    449 U.S. 200
    , 222 (1980).
    Indeed, on numerous occasions, the Supreme Court has applied this general
    principle to find that Congress had authorized or ratified executive branch action
    through appropriation measures. For example, in Isbrandtsen-Moller Co. v. United
    States, 
    300 U.S. 139
    , 147 (1937), the Court held that Congress had ratified the
    abolition of the Shipping Board and the transfer o f its functions to the Department
    o f Commerce by a series of subsequent appropriation acts. Likewise, in Wells
    v. Nickles, 
    104 U.S. 444
    , 447 (1881), the Court found that Congress had author­
    ized the Department of the Interior to appoint agents to protect timber on govern­
    ment land through “ appropriations made to pay for the services of these special
    timber agents.” And in Ludecke v. Watkins, 
    335 U.S. 160
    , 173 n.19 (1948), the
    Court explained that Congress had “ recognized . . . the President’s powers under
    the Alien Enemy Act of 1798” to remove enemy aliens summarily in time of
    declared war “ by appropriating funds” for the maintenance, care, detention,
    surveillance, and transportation of such aliens. See also Ex Parte Mitsuye Endo,
    
    323 U.S. 283
    , 303 n.24 (1944) (noting that to authorize executive action through
    332
    Authorization fo r Continuing Hostilities in Kosovo
    appropriations, Congress “ must plainly show a purpose to bestow the precise
    authority which is claimed” ); Myres S. McDougal & Asher Lans, Treaties and
    Congressional-Executive o r Presidential Agreements: Interchangeable Instruments
    o f National Policy , 54 Yale L J. 181, 271 (1945) (noting that Congressional
    approval of American membership in international organizations such as the Pan-
    American Union “ may readily be inferred from [a] long series of acts appro­
    priating funds to defray the United States’ aliquot portion of operating expenses” ).
    The notion that Congress can authorize hostilities through appropriation laws
    follows directly from this general principle. As Ely explains:
    Throughout the course of the [Vietnam] war, hundreds o f billions
    of dollars were appropriated to support it, and the draft was repeat­
    edly extended. Supporters understandably cited these measures as
    further congressional authorization.
    The law generally pertaining to authorization by appropriation is
    about what first-order common sense suggests it should be. If there
    is no reason to infer that Congress knew what the agency or pro­
    gram in question was about, the fact that it was buried in an appro­
    priations measure is typically not taken to constitute authorization
    of it. If the program was conspicuous, it is. Indeed, assuming suffi­
    cient notice of what was going on, appropriations may in some
    ways constitute unusual evidence of approval, in that typically Con­
    gress acts twice — once lo authorize the expenditure and again to
    appropriate the money.
    Ely, supra, at 27. Indeed, Congress has on numerous occasions authorized U.S.
    involvement in armed conflict at least in part through appropriation laws. As we
    explained in our 1984 overview of the WPR, “ [p]rior to the enactment of the
    WPR, many enactments of Congress, especially appropriations measures, could
    justifiably have been regarded by the Executive as constituting implied authority
    to continue the deployment of our armed forces in hostilities.” 8 Op. O.L.C. at
    273 n.4. In several instances in early Administrations, appropriation laws played
    an important role in authorizing or ratifying presidential use of the Armed Forces
    in situations of conflict. For example, President George Washington “ used force
    against the Wabash Indians pursuant to a statute that provided forces and author­
    ized the call-up of militia to protect frontier inhabitants from the hostile incursions
    of Indians. This statute, along with the requests and debates that accompanied
    it, and the appropriations that follow ed its adoption, made clear that Congress
    approved the military engagements Washington undertook against the Wabash.”

    in the Northwest that “ Congress’ approval of the appropriation . . . constituted

    President Adams to conduct the undeclared Quasi-War against France in part by
    appropriating funds to strengthen the military. See Sofaer, War, Foreign Affairs
    and Constitutional Power, supra at 139-66 (describing appropriation laws and
    other measures by which Congress authorized hostilities against France); Yoo,
    supra, at 292 ( “ Congress approved Adams’ designs to wage a naval war against
    France by supplying the funds for the bulked up military.” ). Another instance
    in which appropriation laws or procurement statutes were thought by some mem­
    bers of Congress to provide some measure of authority for the use of force
    occurred in the course of the Monroe Administration’s efforts to annex Florida.
    See Sofaer, The P ow er Over War, supra, at 47-48 ( “ A long and important
    Congressional debate followed these events. . . . The classic arguments con­
    cerning the meaning of the power to declare war were made on both sides of
    the issue, including the argument that Congress had authorized the actions in
    Florida by providing the funds to pay the m ilitia.” ); see also David P. Currie,
    Rumors o f Wars: Presidential and Congressional War Powers, 1809-1829, 
    67 U. Chi. L. Rev. 1

    gress had authorized President M onroe to order General Jackson to cross into
    Spanish territory to wage defensive war on the Seminoles by appropriating funds
    for the action).
    So-called “ Indian” wars, which were common in American history, were also
    not declared wars; rather, Congress was said to have authorized or ratified them
    by a variety of means, including voting appropriations to pay the troops called
    out and to defray the expenses of campaigns. See Alire v. United States, 
    1 Ct. Cl. 233
    , 238 (1865) (quoting report o f the Secretary of W ar that says: “ And Con­
    gress has seldom failed to recognize and ratify [the so-called ‘Indian wars’], by
    voting appropriations and to pay the troops called out and defray the expenses
    incident to such expeditions.” ), r e v ’d on other grounds, 73 (6 Wall.) U.S. 573
    (1867). In 1838, Attorney General Butler opined that war had been waged on
    the Seminole Indians “ by authority of the legislative department, to whom the
    power o f making war has been given by the constitution,” because Congress had
    both “ recognised the commencement of these hostilities, and appropriated money
    to suppress them ,” and because it had later made “ [s]everal appropriations for
    the same object.” Existence of W ar With the Seminoles, 3 Op. Att’y Gen. 307
    (1838). In 1905, a district court held that President McKinley’s intervention in
    China during the Boxer Rebellion constituted war, and was ratified by Congress’s
    decision to vote wartime pay to the troops who served on the expedition. See
    Hamilton, 136 F. at 451. It has also been argued that Congress ratified the Korean
    War by enacting several major pieces of war-related legislation during that con­
    334
    Authorization fo r Continuing Hostilities in Kosovo
    flict, including a bill to increase taxes by $4.7 billion to help pay for the war.
    See Ely, supra, at 11 (“ [B]efore the war was over Congress had voted draft exten­
    sions and special appropriations which by some people’s lights constituted suffi­
    cient authorization . . . .” ).
    The most conspicuous example of Congress authorizing hostilities through its
    appropriations power occurred during the War in Vietnam. See William C. Banks
    & Peter Raven-Hansen, National Security Law and the Power o f the Purse 119
    (1994) (“ The paradigm of what we have called legitimating appropriations —
    appropriation measures from which the executive infers authority for national
    security actions — is the succession of appropriations for military activities in
    Southeast Asia during the Vietnam War.” ). In that war, the State Department
    Legal Adviser argued that Congress had authorized the conflict, not only through
    the Gulf of Tonkin Resolution, 
    78 Stat. 384
     (1964), but also by enacting supple­
    mental appropriations bills. Noting that the Gulf of Tonkin Resolution provided
    that Congress could terminate that statute by concurrent resolution, and that Con­
    gress had not in fact done so, Leonard Meeker, the State Department’s Legal
    Adviser during the Johnson Administration, pointed out that
    [i]nstead, Congress in May 1965 approved an appropriation of $700
    million to meet the expense of mounting military requirements in
    Viet-Nam. (Public Law 89-18, 
    79 Stat. 109
    .) The President’s mes­
    sage asking for this appropriation state[s] that .this was “ not a rou­
    tine appropriation. For each Member of Congress who supports this
    request is also voting to persist in our efforts to halt Communist
    aggression in South Vietnam.” The appropriation act constitutes a
    clear congressional endorsement and approval of the actions taken
    by the President.
    On March 1, 1966, the Congress continued to express its support
    of the President’s policy by approving a $4.8 billion supplemental
    military authorization by votes of 392-4 and 93-2. An amendment
    that would have limited the President’s authority to commit forces
    to Viet-Nam was rejected by a vote of 94-2.

    o f Viet-Nam, 54 Dep’t St. Bull. 474, 487-88 (1966) (footnote omitted).12
    Five years later, the Solicitor General Erwin Griswold made similar arguments.
    Maintaining that the Vietnam War was congressionally authorized, Griswold said:
    12Senator Eagleton objected to the State Department’s reasoning because “ I could not accept the idea that broad
    appropriations acts authorizing money for a large number o f vital governmental functions could be read as specific
    authorizations for hostilities.” Eagleton, supra, at 125. However, the Slate Department’s argument rested, not on
    such broad appropriation acts, but on specific appropriations for the war in Vietnam See Pub L No 89-18, 79
    Stat 109 (1965) (appropriating $700 million “ upon determination by the President that such action is necessary
    in connection with military activities in southeast Asia” )

    Opinions o f ihe Office o f Legal Counsel in Volume 24
    Perhaps even more important than the Tonkin Gulf Resolution is
    the fact that Congress has consistently backed and supported the
    actions of the President in all the intervening years. Early in 1965,
    President Johnson asked for and obtained a special appropriation
    of seven hundred million dollars, for the express purpose of car­
    rying on military action in Southeast Asia. This was granted by
    an Act of Congress approved on May 7, 1965. The vote in Congress
    was 408 to 7 in the House, and 83 to 3 in the Senate. This is
    an unusual appropriations act, in that it consists of a single item.
    Thus, there is no possibility that it passed through Congress by
    inadvertence, or that the report for it may have been coerced, as
    in the case of a rider. . . . After this, there were many legislative
    acts by Congress, taken in full knowledge of the situation in South­
    east Asia, and in support of the President’s actions.

    Rec. 28,978 (1971).
    Several courts and legal scholars have agreed that the appropriations provided
    by Congress to fund the war played an important (and in some cases dispositive)
    role in authorizing armed conflict in Vietnam. For example, directly following
    his observation that Congress can authorize executive action through appropria­
    tions if the program in question is “ conspicuous,” Professor Ely notes: “ In this
    case, it would be an understatement to say that the program for which Congress
    was appropriating funds (and extending the draft) was conspicuous. In May of
    1965 Congress enacted a special appropriation of $700 million for ‘military activi­
    ties in southeast Asia.’ ” Ely, supra, at 27; see also id. at 27-30 (explaining why
    appropriations constituted authorization and rejecting arguments to the contrary);

    lions o f dollars to carry on military and naval operations in Vietnam to ratify
    and approve the measures taken by the Executive, even in the absence of the
    Gulf o f Tonkin resolution.” ); Berk,

    tion of the Vietnam War, and Ely forthrightly, and, I think, courageously,
    acknowledges this.” ); Norman A. Graebner, The President As Commander in

    purse; that war always belonged to Congress as much as to the presidents. They
    fought it together.” ).13
    Finally, although the court of appeals in Holtzman v. Schlesinger, 
    484 F.2d 1307
    , 1313 (2d Cir. 1973), invoked the political question doctrine and thus did
    not reach the merits of the claim that President Nixon lacked the authority for
    the bombing of Cambodia after the cease-fire in Vietnam and the removal of
    United States prisoners of war from that country, it indicated that, if it had reached
    the merits, it would have found that a provision of the Joint Resolution Continuing
    Appropriations for Fiscal 1974, Pub. L. No. 93-52 (1973), “ support[ed] the propo­
    sition that the Congress has approved the Cambodian bombing.” See also Thomas
    F. Eagleton, The August 15 Compromise and the War Powers o f Congress, 18
    St. Louis U. L.J. at 1 (“ On June 29 . . . [i]t was clear that neither the American
    people nor Congress wanted a continuation of the bombing. But before that legis­
    lative day was over, Congress would authorize a forty-five day war in Indo­
    china.” ).
    Some have argued that, on the contrary, appropriation statutes that fund ongoing
    war efforts do not constitute authorization of those war efforts. See Francis D.
    Wormuth & Edwin B. Firmage, To Chain the Dog o f War: The War Pow er of

    672, §12, 
    84 Stat. 2053
    , 2055 (1971) (repealing Gulf o f Tonkin Resolution), C ongress’ continuing appropriations
    for the war effort were sufficient to authonze continuing hostilities in Vietnam. As Ely notes
    [The intentions o f those who voted to repeal the Tonkin Gulf Resolution] would not have mattered, had
    the Tonkin G ulf Resolution stood as o f 1971 as the only congressional authorization for the war- When
    the only authorization goes, the war goes, irrespective o f what people think they are up to However,
    by 1971 the situation was far from that: Congress had by then, by a number of appropriations measures,
    quite pointedly reiterated its authorization of the war. Moreover, and not surprisingly under the cir­
    cumstances, it continued after its repeal of the Tonkin Gulf Resolution to appropriate funds for military
    activities in Southeast Asia, and to extend the draft
    Tantalizing as the repeal must thus have seemed to those wishing to mount a legal attack on the war,
    it unfortunately was just more o f C ongress’s playing Pontius Pilate

    his salary.” ); M itchell, 
    488 F.2d at 615
     (“ This court cannot be unmindful of what
    every schoolboy knows: that in voting to appropriate money or to draft men a
    Congressman is not necessarily approving of the continuation of a war no matter
    how specifically the appropriation or draft act refers to that war.” ); Campbell,
    
    203 F.3d at
    31 n.10 (Randolph, J., concurring) (citing and quoting Mitchell for
    the same proposition). This argument can take one of two forms. First, one could
    argue that a general defense-related appropriation statute does not authorize the
    ongoing hostilities because it provides only general defense-related funds and does
    not indicate any approval o f the specific hostilities at issue. While this might be
    true, it does not undermine the basic principle explained above — that an appro­
    priation statute specifically and conspicuously aimed at funding hostilities may
    constitute authorization of those hostilities. Second, some have argued that appro­
    priations, regardless of how specific they may be with respect to ongoing war
    efforts, should not be interpreted to authorize continuing military operations
    because those appropriations could just as easily be understood as providing
    resources for men and women already in combat, simply to ensure that they do
    not suffer as a result of a disagreement between the Executive and the Congress
    regarding the wisdom of the deployment. See, e.g., Mitchell, 
    488 F.2d at 615
    (declining to decide whether President Nixon had exceeded his constitutional
    power on political question grounds, but noting that, “ in voting to appropriate
    money or to draft men a Congressman is not necessarily approving the continu­
    ation of a war no matter how specifically the appropriation or draft act refers
    to that war. . . . An honorable, decent, compassionate act of aiding those already
    in peril is no proof of consent to the actions that placed and continued them in
    that dangerous posture.” ).14 Although this may be true in some cases, in other
    cases, as Ely explains, this proposition “ doesn’t make sense . . . [because] Con­
    gress could [phrase] its funds cut-off as a phase out, providing for the protection
    of the troops as they [are] withdrawn.” Ely, supra, at 29. Congress took such
    a step with respect to hostilities in Somalia in November of 1993, when it provided
    that funds could be obligated beyond March of 1994 only “ to protect American
    diplomatic facilities and American citizens, and noncombat personnel to advise
    the United Nations commander in Somalia.” Pub. L. No. 103-139,
    § 8151(b)(2)(B), 
    107 Stat. 1418
    , 1476 (1993). Alternatively, Congress could pre­
    clude the use o f funds to introduce additional troops, as it did through the 1971
    Cooper-Church Amendment, which provided that “ none of the funds authorized
    or appropriated pursuant to this or any other Act may be used to finance the
    introduction of United States ground combat troops into Cambodia, or to provide
    United States advisers to or for Cambodian military forces in Cambodia.” Pub.
    14 See also Note, Congress, The President, and the Power to Commit Forces to Combat, 81 Harv. L Rev 1771,
    1801 (1968) ( “ The difficulty with the argument [that appropriations constitute approval of warmaking] is that since
    such appropriations must generally come after the hostilities have already begun, the effective choice remaining
    to Congress is likely to be severely limited ” )
    338
    Authorization fo r Continuing Hostilities in Kosovo
    L. No. 91-652, §7(a), 
    84 Stat. 1942
    , 1943 (1971).15 In the end, the question
    whether a particular targeted appropriation constitutes authorization for continuing
    hostilities will turn on the specific circumstances of each case.16
    In sum, basic principles of constitutional law — and, in particular, the fact that
    Congress'may express approval through the appropriations process — and histor­
    ical practice in the war powers area, as well as the bulk of the case law and
    a substantial body of scholarly opinion, support the conclusion that Congress can
    authorize hostilities through its use of the appropriations power. Although it might
    be the case that general funding statutes do not necessarily constitute congressional
    approval for conducting hostilities, this objection loses its force when the appro­
    priations measure is directly and conspicuously focused on specific military action.
    III. Appropriations and the War Powers Resolution
    This section analyzes whether the WPR bars Congress from authorizing military
    operations through an appropriation measure unless the appropriation measure
    “ states that it is intended to constitute specific statutory authorization within the
    meaning of this chapter.” 
    50 U.S.C. § 1547
    (a)(1) (section 8(a)(1) of the WPR).
    We conclude that the WPR does not constitute such a bar, but instead has the
    effect of establishing a background principle against which to interpret later Acts
    of Congress.
    Section 5(b) of the WPR permits continuation of hostilities when a congres­
    sional enactment represents “ specific authorization for such use of United States
    Armed Forces.” 
    50 U.S.C. § 1544
    (b). As has been discussed, courts, government
    officials, and scholars have repeatedly (although not uniformly) recognized that
    appropriation statutes may constitute authorization for conflict. Thus, if the WPR
    did not provide any further interpretive gloss on the question, it would appear
    that an appropriation statute — if enacted for the purpose of continuing hos­
    tilities— would be “ specific authorization.” Section 8(a) of the WPR, however,
    provides that authority “ shall not be inferred . . . from any provision of law
    15 Banks and Raven-Hansen explain ihe difficulty with the objection lhat it is impossible to construe national
    security appropriations as ratification because of the circumstances o f their enactment'
    The objection is exaggerated and ahistoncal It seems to proceed on the assumption that Congress’s choices
    are all or nothing, fund or deny all funding. But the Vietnam War itself showed lhat Congress has inter­
    mediate options, including funding phaseouts, prospective cutoffs, and, subject to separation o f powers
    limits, area limitations. In fact, given ihe scope o f ihe president’s commander-in-chief powers, it is doubtful
    that Congress constitutionally could eul off the funds so abruptly that American lives would be placed
    ai grave risk
    Banks & Raven-Hansen, supra, at 135 In addition to the Vietnam phase-out appropriations, Banks and Raven-
    Hansen also point to the Boland Amendments, which limited how funds appropriated for support of the Contras
    could be used, see, e g .. Pub. L. No. 97-377, §793, 
    96 Stat. 1830
    , 1865 (1982) (providing that funds could not
    be used by the Central Intelligence Agency or the Department o f Defense to “ furnish military equipment, military
    training o r advice . . . for the purpose o f overthrowing the Government of Nicaragua or provoking a military
    exchange between Nicaragua and Honduras” ), as an example o f such a “ restrictive appropriation ” See Banks &
    Raven-Hansen, supra, at 137-48.
    16 We explain in Part IV, infra, why the circumstances here lead us to conclude that Pub L No 106-31 constituted
    authorization for continuing hostilities in the Federal Republic of Yugoslavia
    339
    Opinions o f the Office o f Legal Counsel in Volume 24
    . . . including any provision contained in any appropriations Act, unless such
    provision specifically authorizes the introduction of United States Armed Forces
    into hostilities or into such situations and states that it is intended to constitute
    specific statutory authorization within the meaning of this chapter.” 
    50 U.S.C. § 1547
    (a). In assessing whether an appropriation statute can constitute authoriza­
    tion, the critical question thus becomes how to understand section 8(a)(1).
    The precursor of section 8(a)(1) is section 3(4) of S. 440, the version of the
    WPR passed by the Senate. That section provided that a specific statutory
    authorization shall not be inferred (A) from any provision of law hereafter enacted,
    including any provision contained in any appropriations Act, unless such provision
    specifically authorizes the introduction of such Armed Forces in hostilities . . .
    and specifically exempts the introduction of such Armed Forces from compliance
    with the provisions of this Act.17
    The most significant interpretive guide to this language is the Senate Report,
    which stated: “ The purpose of this clause is to counteract the opinion in the
    Orlando v. Laird decision of the Second Circuit Court holding that passage of
    defense appropriations bills, and extension of the Selective Service Act, could
    be construed as implied Congressional authorization for the Vietnam war.” S.
    Rep. No. 93-220, at 25. In Orlando, the court o f appeals had rejected the argument
    of the plaintiff enlisted men that “ congressional authorization cannot, as a matter
    of law, be inferred from military appropriations or other war-implementing legisla­
    tion that does not contain an express and explicit authorization for the making
    of war by the President.” 
    443 F.2d at 1043
    .
    The House version of the WPR did not contain an analogous provision.18 The
    Conference Report indicates that the Senate version was the source of the “ spe­
    cific statutory authorization” language in the final bill. See H.R. Conf. Rep. No.
    93-547, at 2 (1973). That language, according to the Senate report on S. 440,
    was intended to “ guard against the passage of another resolution of the Tonkin
    Gulf type” by requiring that “ any area resolutions, to qualify under this bill as
    a grant o f authority to introduce the armed forces into hostilities . . . meet certain
    carefully drawn criteria — as spelled out in the language of [§ 8(a)(1)].” S. Rep.
    No. 93-220, at 24. The Report further explained that “ authorization to continue
    using the Armed Forces is to come in the form o f specific statutory [authorization]
    for this purpose. This is to avoid any ambiguities such as possible efforts to con­
    strue general appropriations or other such measures as constituting the necessary
    17 S 440, as passed by the Senate on July 20, 1973, is reprinted in William B Spong, Jr., The War Powers
    Resolution Revisited: Historic Accomplishment or S u r r e n d e r 16 W m & Mary L. Rev 823, 878-82 (1975).
    l8Section 4(b) o f H.J. Res. 542, passed by the House on July 18, 1973, provided that “ [w]ithin one hundred
    and twenty calendar days after a report is submitted o r is required to be submitted pursuant to section 3, the President
    shall term inate any commitment and remove any enlargement o f United States Armed Forces with respect to which
    such report was submitted, unless the Congress enacts a declaration o f war or a specific authorization for the use
    of United States Armed Forces,” but the House version neither defined “ specific authorization” nor provided that
    an appropriations measure not refem n g back to th e WPR could not constitute such an authorization. See Spong,
    supra, at 874—77 (reprinting H J. Res. 542)
    340
    Authorization fo r Continuing Hostilities in Kosovo
    authorization for such ‘continued use.’ ” Id. at 29. Congress thus required that
    authorizing legislation expressly reference the WPR to avoid “ any ambiguities”
    regarding congressional intent to sanction continued hostilities.
    To the extent, however, that this interpretation would take from Congress a
    constitutionally permissible method of authorizing war, it runs afoul of the axiom
    that one Congress cannot bind a later Congress. See, e.g., Marbury v. Madison,
    5 U.S. (1 Cranch) 137, 177 (1803) (noting that, in contrast to a constitution, legis­
    lative acts are “ alterable when the legislature shall please to alter [them]” );
    Fletcher v. Peck, 10 U.S. (6 Cranch) 87, 135 (1810) (noting that “ [t]he correctness
    of [the] principle,” “ that one legislature is competent to repeal any [law] which
    a former legislature was competent to pass, and that one legislature cannot abridge
    the powers of a succeeding legislature,” “ can never be controverted” ); Street
    v. United States, 
    133 U.S. 299
    , 300 (1890) (statute “ was not intended to have,
    [and] could not have, any effect on the power of a subsequent Congress” to enact
    a different policy).19 Underlying this axiom is the principle that one Congress
    cannot surrender through legislation power that the Constitution vests in Congress.
    To believe otherwise would be to assume that “ new legislators [could] automati­
    cally be bound by the policies and undertakings of earlier days.” United States
    Trust Co., 431 U.S. at 45 (Brennan, J., dissenting).
    Applying this general principle to the issue of section 8(a)(l)’s constitutionality,
    Professor Philip Bobbitt has argued that, were section 8(a)(1) read to bind subse­
    quent Congresses, it would be unconstitutional:
    [F]ramework statutes — like Gramm-Rudman, for example —
    cannot bind future Congresses. If Congress can constitutionally
    authorize the use of force through its appropriations and authoriza­
    tion procedures, an interpretive statute that denies this inference —
    as does . . . the original War Powers Resolution — is without legal
    effect. On the other hand, if one Congress could bind subsequent
    Congresses in this way, it'would effectively enshrine itself in defi­
    ance of [an] electoral mandate. Imagine, for example, a statute that
    provided that no appropriations or authorization provision shall
    exceed a term of six months or an act that forbade the President
    from interpreting any subsequent statute as permitting him to issue
    regulations to enforce that statute unless specifically authorized to

    do so therein. A rule of interpretation, if it contravenes a valid con­
    stitutional power — in this case, . . . that a subsequent Congress
    could constitutionally endorse a war by an appropriations and
    authorization statute — would amount to a restriction on the ability
    of a Congress to repeal by inference preexisting law. Such a fresh
    hurdle to later legislation is nowhere authorized by the Constitution
    and is inconsistent with the notion of legitimacy derived through
    the mandate o f each new Congress.

    This argument is compelling. If section 8(a)(1) were read to block all possibility
    of inferring congressional approval of military action from any appropriation,
    unless that appropriation referred in terms to the WPR and stated that it was
    intended to constitute specific authority for the action under that statute, then it
    would be unconstitutional. As discussed in the previous section, under the Con­
    stitution, Congress can authorize or ratify presidential engagement in hostilities
    through an appropriation law. One statute, such as the WPR, cannot mandate that
    certain types of appropriation statutes that would otherwise constitute authorization
    for conflict cannot do so simply because a subsequent Congress does not use
    certain “ magical passwords.” M arcello v. Bonds , 
    349 U.S. 302
    , 310 (1955)
    (holding that detailed procedures established by the Immigration and Naturaliza­
    tion Act applied despite discrepancies between that Act and the Administrative
    Procedure Act (“ APA” ) and despite the fact that the APA provided that exemp­
    tions from its requirements must be expressly indicated). As Banks and Raven-
    Hansen have put it, “ [i]t follows that the 93d Congress that enacted the War
    Powers Resolution cannot control the way in which [a later] Congress expressfes]
    their intent.” Banks & Raven-Hansen, supra, at 131.
    In order to avoid this constitutional problem, we do not interpret section 8(a)(1)
    as binding future Congresses but instead as having the effect of estabUshing a
    background principle against which Congress legislates. In our view, section
    8(a)(1) continues to have operative legal effect, but only so far as it operates
    to inform how an executive or judicial branch actor should interpret the intent
    20 In Congressional testimony in 1986, the Legal Adviser to the State Department, Abraham Sofaer, found that
    “ senous constitutional problems exist with respect to Section 8(a),” because “ one Congress by statute can[not]
    so limit the constitutional options o f future Congresses.” See Abraham D. Sofaer, The War Powers Resolution and
    Antiterronst Operations, 86 Dept St. Bull 68, 69 (Aug 1986). In 1988, however, Judge Sofaer cast the problem
    prim anly as a matter o f construction, not of constitutionality, although it would appear that Judge Sofaer’s construc­
    tion o f the statute was intended to avoid constitutional concerns See The War Power After 200 Years Congress
    and the President at a Constitutional Impasse H earings Before the Special Subcomm. On War Powers o f the Senate
    Comm. On Foreign Relations, 100th Cong 148 (1988) (testimony o f Legal Adviser Sofaer) ( “ Section 8. The problem
    there is not so much constitutional          Section 8 was an effort to get people to focus on the W ar Powers Resolu­
    tion, but not an effective effort in limiting the types o f approvals that can be obtained.” ), id. at 1066 (“ In our
    view, Section 8(a) ineffectively attempts to restnct the rights o f future Congresses to authorize deployments in any
    way they choose ” ). As President Nixon correctly said in his Veto M essage following initial passage of the WPR,
    Congress can affect the Executive’s conduct of m ilitary operations through a vanety of means, and “ Itjhe authonza-
    tion and appropnations process represents one o f the ways in which such influence can be exercised.” Pub Papers
    of Richard Nixon 893, 895 (1973).

    Authorization fo r Continuing Hostilities in Kosovo
    of subsequent Congresses that enact appropriation statutes that, do not specifically
    reference the WPR.21 On the question whether an appropriation statute enacted
    by a subsequent Congress constitutes authorization for continued hostilities, it is
    the intent of the subsequent Congress, as evidenced by the text and legislative
    history of the appropriation statute, that controls the analysis. The existence of
    section 8(a)(1) might affect this analysis. If the appropriation statute is entirely
    ambiguous as to whether it constitutes authorization for continuing hostilities, for
    example, it might be proper for a judicial or executive branch actor to conclude
    that, because the subsequent Congress was aware of the background principle
    established by section 8(a)(1), its failure to refer specifically back to the WPR
    evidences an intent not to authorize continuing hostilities. If, however, Congress,
    in enacting an appropriation statute, demonstrates a clear intent to authorize con­
    tinuing hostilities, then it would be appropriate to conclude that the appropriation
    statute does authorize those hostilities, even though the statute does not specifi­
    cally refer back to the WPR. Under these circumstances, the appropriation statute
    would supersede or work an implied partial repeal of section 8(a)(1).22 In other
    words, section 8(a)(1) establishes procedural requirements that, under the statute,
    Congress must follow to authorize hostilities; nonetheless, a subsequent Congress
    remains free to choose in a particular instance to enact legislation that clearly
    authorizes hostilities and, in so doing, it can decide not to follow the W PR’s
    procedures. This position is consistent with the approach taken by our Office at
    about the time of the WPR’s enactment. In a 1973 opinion, we stated:
    Strictly speaking, such a provision [§ 8(a)(1)] is probably not
    binding on future Congresses. For example, should the legislative
    history of a future appropriations statute make it clear that particular
    hostilities are authorized, that should constitute a valid authoriza­
    tion, because future Congresses are free to adopt any of the cus­
    tomary modes of manifesting their intention. However, as a prac­
    tical matter, a court would probably attach some significance to
    this subsection should a claimed statutory authorization for hos­
    tilities be doubtful.

    that canons of construction have “ actually influenced judicial behavior insofar as they reflected background norms
    lhat helped to give meaning to statutory words or to resolve hard cases” )
    22 Although the law disfavors implied repeals, particularly with respect to appropriation statutes, see Tennessee
    Authority v. Hill, 
    437 U.S. 153
    , 190 (1978), the presumption against implied repeals can be overcome if the statutory
    language o r legislative history evidences an intent ro repeal the prior statute. See WiU, 449 U.S at 222 ( “ [WJhen
    Congress desires to suspend or repeal a statute in force, there can be no doubt that . . it could accomplish its
    purpose by an amendment to an appropriation bill, or otherwise . . The whole question depends on the intention
    of Congress as expressed in the statutes.” (citations and internal quotation marks omitted)) As described below,
    this standard is satisfied here.

    Opinions o f the Office o f Legal Counsel in Volume 24
    Memorandum for the Hon. William E. Timmons, Assistant to the President for
    Legislative Affairs, from Robert G. Dixon, Assistant Attorney General, Office of
    Legal Counsel, Re: The “ War Powers Resolution" at 15 (Nov. 16, 1973).
    This reading of section 8(a)(1) finds support in a series of cases interpreting
    statutes similar in form to section 8(a)(1). For example, in the case of Great N.
    Ry. Co. v. United States, 
    208 U.S. 452
     (1908), the Court addressed whether one
    criminal law repealed a prior criminal law so as to deprive the government of
    the right to prosecute for violations o f the prior law committed before the subse­
    quent law was enacted. The Court considered this question in light of section
    13 of the Revised Statutes,23 which provided that “ [t]he repeal of any statute
    shall not have the effect to release or extinguish any penalty . . . incurred under
    such statute, unless the repealing act shall so expressly provide.” 
    Id. at 465
    . In
    addressing the effect of section 13 on the interpretation of the subsequent criminal
    law, the Court wrote: “ As the section of the Revised Statutes in question has
    only the force of a statute, its provisions cannot justify a disregard of the will
    of Congress as manifested, either expressly or by necessary implication, in a sub­
    sequent enactment.” 
    Id.
     The Court observed that section 13 “ must be enforced
    unless, either by express declaration or necessary implication, arising from the
    terms of the law as a whole, it results that the legislative mind will be set at
    naught by giving effect” to that section. 
    Id.
     See also Hertz v. Woodman, 
    218 U.S. 205
    , 218 (1910) (“ The repealing act here involved includes a saving clause,
    and if it necessarily, or by clear implication, conflicts with the general rule
    declared in § 13, the latest expression of the legislative will must prevail.” ); War­

    417 U.S. 653
    , 659 n.10 (1974) (“ [0]nly if [the subsequently
    enacted statute] can be said by fair implication or expressly to conflict with [the
    previously enacted saving clause] would there be reason to hold that [the subse­
    quently enacted statute] superseded [the saving clause].” ); Passamaquoddy Tribe
    v. M aine, 
    75 F.3d 784
    , 787, 789 (1st Cir. 1996) (characterizing a law that provided
    that “ [t]he provisions of any federal law . . . for the benefit of Indians . . . shall
    not apply within the State of Maine, unless such provision of such subsequently
    enacted Federal law is specifically made applicable within the State of Maine”
    as “ an interpretive aid [that] serves both to limn the manner in which subsequendy
    enacted statutes should be written to accomplish a particular goal and to color
    the way in which such statutes thereafter should be read,” and noting that “ [the
    law] binds subsequent Congresses only to the extent that they choose to be
    bound” ). The Supreme Court’s observation that a statute should not be given
    effect if, “ by express declaration o r necessary implication, arising from the terms
    of the law as a whole, it results that the legislative mind will be set at naught,”
    G reat N. Ry. Co., 
    208 U.S. at 465
    , is consistent with the view expressed in our
    1973 opinion that a statute evidencing a “ clear” intent to authorize hostilities
    will operate to authorize those hostilities even though it does not refer back to
    23 Rev. Stat § 13, U.S. Comp. Stat 1901, p 6.
    344
    Authorization fo r Continuing Hostilities in Kosovo
    the WPR. To interpret section 8(a)(1) to bar such a statute from authorizing hos­
    tilities would set the “ legislative mind” that enacted the appropriation statute “ at
    naught.” 24
    Academic commentators have understood section 8(a)(1) in a similar fashion.
    Professors Banks and Raven-Hansen, for example, have argued that although sec­
    tion 8(a)(1) counsels against inferring authorization from an ambiguous appropria­
    tion law, an appropriation statute that clearly authorizes hostilities nonetheless con­
    stitutes authorization for those hostilities despite section 8(a)(1):
    We conclude . . . that the resolution’s clear statement requirement
    does not control the construction of subsequent appropriations or
    other legislation. Instead, absent ambiguities, it is their own plain
    words and their enactors’ legislative intent that controls their
    construction. As a result, a legitimating appropriation may authorize
    or ratify a deployment of U.S. armed forces into hostilities even
    if it omits the resolution’s magic passwords and thus violates its
    clear statement provision. . . . This is not to make a dead letter
    out of the whole of the War Power Resolution’s rule of construc­
    tion. Its self-referential insistence on “ passwords” is without effect.
    We never have occasion to need the rest of it, if we can ascertain
    the meaning and intent of a legitimating appropriation from its plain
    words or clear legislative history. If we cannot, then the resolution’s
    clear statement requirement sounds a useful advisory caution
    against inferring authority from ambiguous appropriations meas­
    ures, and thus operates like any canon of statutory construction,
    by supplying helpful, but not controlling guidance in statutory
    construction.
    Banks & Raven-Hansen, supra, at 129, 131. Similarly, Professor Ely writes that
    section 8(a)(1) “ gave us [] a strong rule of construction, telling us how to read
    the intent of later congresses,” although he further notes that unless the Resolution
    is repealed, a subsequent congress can only authorize hostilities through an appro­
    priation statute under “ extreme circumstances.” Ely, supra, at 129.25
    24 The Great Northern Court looked solely to the subsequent statute’s text to determine whether it conflicted
    with the prior statute See 208 U S at 466-70. As we explain below, under a pure textual analysis. Pub L No.
    106-31 evidences a clear intent to authorize hostilities despite section 8(a)(1) In at least one recent case, however,
    a court looked both to text and legislative history to determine whether a subsequent statute repealed a pn o r statute
    See Passamaquoddy, 
    75 F.3d at 790-91
     (analyzing Senate Report), see also Will, 499 U S at 222 In our view,
    this approach is more consistent with the current practice o f statutory interpretation See, e g , Murphy Bros, Inc
    v. Michetti Pipe Stringing, In c , 526 U S 344, 351-55 (1999) (analyzing text and legislative history in resolving
    statutory interpretation question) We explain below why the legislative history also supports our interpretation of
    Congress’s intent in enacting Pub. L. No. 106-31
    25 Although we agree generally with the approach of Banks and Raven-Hansen, we are reluctant to characterize
    section 8(a)(1) as a “ rule o f construction ” Such a charactenzauon might be read to suggest that the Congress
    that enacted section 8(a)(1) intended it simply as one measure of how to interpret the intent of subsequent Congresses,

    Opinions o f the Office o f Legal Counsel in Volume 24
    The determination of whether any particular appropriation statute that does not
    refer back to the WPR constitutes authorization for continuing hostilities will nec­
    essarily depend on the facts of each case. Certain types of evidence will be highly
    probative of an intent to authorize ongoing military operations. For example, evi­
    dence demonstrating that Congress was concerned with funding a specific military
    effort, as opposed to making general defense appropriations, would tend to show
    such an intention. Likewise, in a case where the President has requested an appro­
    priation in order to continue military operations, evidence showing that Members
    of Congress were specifically aware o f the purposes of the appropriation request
    will tend to show that Congress intended to authorize continuing military oper­
    ations as required by the WPR. Finally, if Congress appropriates funds only for
    protection o f troops already committed or prohibits the use of appropriated funds
    for the introduction of new troops, a presumption might arise that Congress did
    not intend to authorize continuing hostilities but instead intended simply to protect
    troops already on the ground. On the other hand, unlimited appropriations would
    tend to suggest an intent to authorize continuing hostilities. In short, where Con­
    gress, in passing an appropriations bill, clearly intends to authorize conflict, the
    WPR cannot be read to deny legal effect to that clear intent.
    IV. Pub. L. No. 106—31 and Congressional Authorization o f the War in Kosovo
    This section shows that, in passing Pub. L. No. 106-31, Congress clearly
    intended to authorize continuing military operations in Kosovo. The section begins
    by providing an overview of the events in Congress leading to the passage of
    Pub. L. No. 106-31 and of the statute’s text. It concludes that, in the absence
    of the WPR, Pub. L. No. 106-31 would have constituted congressional authoriza­
    tion of military operations in Kosovo. The following three parts look closely at
    the statute’s text and legislative history to determine whether Pub. L. No. 106-
    31 constituted “ specific authorization” under section 5(b)(2) of the WPR. It con­
    cludes that the statute constituted such “ specific authorization.”
    1. O verview
    The “ clock” established in section 5(b) of the WPR began running in the
    present case on March 26, 1999, when the President, citing national security con-
    a view which seems in tension with the language and purpose o f the WPR. We nonetheless agree that, in effect,
    section 8(a)(1) operates like a rule o f construction. Likewise, although we agree with Professor Ely that section
    8(a)(1) “ tell[s] us how to read the intent of later congresses,” we are reluctant to agree with his characterization
    of the section as “ a strong rule o f construction ” Ely, supra, at 129. W e also do not agree with Ely that a subsequent
    Congress can authonze hostilities through appropriations only in “ extreme circumstances.” Id In other words, section
    8(a)(1) establishes procedural requirements that a subsequent Congress must follow to authonze hostilities, unless
    that subsequent Congress decides not to follow those procedures and instead chooses to enact legislation that
    “ expressly o r by necessary im plication,” Great N Ry., 208 U S at 465, authorizes hostilities (A subsequent Con­
    gress could, o f course, also choose to repeal section 8(a)(1) o f the W PR o u tn g h t)

    Authorization fo r Continuing Hostilities in Kosovo
    cems, informed Congress that U.S. military forces had begun a series of air strikes
    in the Federal Republic of Yugoslavia. See Letter to Congressional Leaders
    Reporting on Airstrikes Against Serbian Targets in the Federal Republic of Yugo­
    slavia (Serbia and Montenegro), 1 Pub Papers of William J. Clinton 459 (1999).
    As the President explained to the Speaker of the House:
    At approximately 1:30 p.m. eastern standard time, on March 24,
    1999, U.S. military forces, at my direction and in coalition with
    our NATO allies, began a series of air strikes in the Federal
    Republic of Yugoslavia (FRY) in response to the FRY govern­
    ment’s continued campaign of violence and repression against the
    ethnic Albanian population in Kosovo. The mission of the air
    strikes is to demonstrate the seriousness of NATO’s purpose so that
    the Serbian leaders understand the imperative of reversing course;
    to deter an even bloodier offensive against innocent civilians in
    Kosovo; and, if necessary, to seriously damage the Serbian mili­
    tary’s capacity to harm the people of Kosovo. In short, if President
    Milosevic will not make peace, we will limit his ability to make
    war.
    Id. The President concluded the letter by informing the Speaker, as is customary,
    that he was “ providing th[e] report as part of [his] efforts to keep the Congress
    fully informed, consistent with the War Powers Resolution.” Id. at 460.
    Approximately three weeks after sending this letter, the President, through the
    White House budget officc, formally submitted a request to Congress for $6 billion
    to fund continuing efforts in Kosovo. See Guy Gugliotta & Helen Dewar, $6 Bil­
    lion Requested fo r Kosovo Emergency , The Washington Post, April 20, 1999, at
    A15. Of this amount, close to $5 billion was to be used for continued air oper­
    ations and war material through September 30, 1999, and the rest was intended
    to assist the hundreds of thousands of ethnic Albanian refugees who were fleeing
    from Kosovo. Id. The congressional leadership promptly made clear their intention
    to use the request as a vehicle to augment defense spending more generally and
    called for defense funding far in excess of the requested $6 billion. Id. (indicating
    House Majority Leader Richard K. Armey’s belief that “ [e]ven $10 billion would
    be insufficient” ).
    Debate over the continuing military operations in Kosovo intensified on April
    28, 1999, when the House considered and voted on four different Kosovo-related
    measures.26 First, the House defeated two measures introduced by Representative
    26Pnor lo these measures, the Senate, on March 23,      1999, passed a concurrent resolution providing that “ the
    President o f the United States is authonzed to conduct   military air operations and missile stnkes in cooperation
    with our NATO allies against the Federal Republic o f     Y ugoslavia” 145 Cong Rec. S3118 (daily ed. Mar. 23,
    1999) (repnnting S. Con Res 21, 106th Cong (1999))        The following day, the House passed, by a vote of 42 4 -

    and H.J. Res. 44, 106th Cong. (1999), declaring a state of war between the United
    States and Serbia. See 145 Cong. Rec. H2414 (daily ed. Apr. 28, 1999) (reprinting

    support H.R. 1569, 106th Cong. (1999), blocking funding for ground troops with­
    out additional specific authorization from Congress, see 145 Cong. Rec. H2400
    (reprinting measure); id. at H2413-14 (recording votes), and tied, 213-213, on
    S. Con. Res. 21, 106th Cong. (1999), a concurrent resolution stating that the Presi­
    dent “ is authorized to conduct military air operations and missile strikes” against
    Serbia. See id. at H2441 (reprinting resolution); id. at H2451-52 (recording vote).
    As highlighted by the debates concerning these measures, there can be no doubt
    that members of Congress were fully cognizant of the WPR and the 60-day time
    clock.27
    Despite these votes, the appropriation effort moved forward. Following testi­
    mony by Secretary of Defense Cohen before the Subcommittee on Defense on
    April 21, and after a public markup on April 29, the House Appropriations Com­
    mittee reported H.R. 1664, 106th Cong. (1999), entitled “ [a] bill making emer­
    gency supplemental appropriations for military operations, refugee relief, and
    humanitarian assistance relating to the conflict in Kosovo, and for military oper­
    ations in Southwest Asia for the fiscal year ending September 30, 1999, and for
    other purposes,” to the full House on May 4. 145 Cong. Rec. H2634 (daily ed.
    May 4, 1999). The $12.9 billion bill provided the funds requested by the President
    for military operations in Kosovo, as well as over $6 billion in other military
    funding, for such things as spare parts, depot maintenance, recruiting, and readi­
    ness training. See H.R. 1664, ch. 3; see also Andrew Taylor, Paying fo r the

    I, a resolution noting the President’s authorization o f U S. participation in NATO military operations and resolving

    1999) (reprinting H.R Res. 130, 106th Cong. (1999))
    27 For exam ple, Congressman Spratt pointed o u t that “ [wjithin 60 days of a deployment, when we are notified
    by the President, we can enact a specific authorization o f such use o f the Armed Forces. That was laid out for
    us when we passed the W ar Powers Resolution ” Id. at H2387. Other speakers made similar points See id at
    H 2386 (remarks o f Cong Cham bliss) (“ I do not think that now is the time to have a constitutional showdown
    on the W ar Powers Act ” ), id at H2389 (remarks o f Cong. Stark) (H. Con. Res. 82 “ is of the highest priority
    because we m ust exercise our obligation under the War Powers Act to debate the use of military force” ), id at
    H2423 (rem arks o f Cong. Leach) ( “ The vote [w e take] on this resolution and the others we will take today are
    necessitated by .     the W ar Powers Resoluuon ” ). Still more pointedly, Congressman Kucinich reminded the House
    that “ Section 5 o f the W ar Powers Resolution states that the President must terminate the use o f force after 60
    days unless Congress, first, declares war, second, enacts explicit authorization of the use of force; or third, extends
    the 60-day period ” Id. at H2446.

    Authorization fo r Continuing Hostilities in Kosovo
    The next week, the House and Senate held a joint conference on H.R. 1664
    and H.R. 1141, 106th Cong. (1999), another emergency supplemental funding bill
    that up to that point had focused on providing relief to Central American nations
    devastated by hurricanes. During the three day conference, the conferees stripped
    H.R. 1664 of the appropriations relating to Kosovo and other military funding
    and added those appropriations to H.R. 1141. See H.R. Conf. Rep. No. 106-143,
    at 61 (1999) ( “ The conferees have agreed to include in this conference report
    on H.R. 1141 matters addressed in the House version of H.R. 1664 as an expedient
    approach to getting appropriations enacted into law for the important requirements
    related to the conflict in Kosovo and Southwest Asia (Operation Desert Fox).” ).
    As the conference report explained, “ the conference agreement recommend[ed]
    a total of $10,196,495,000 in new budget authority for the Department of Defense,
    for costs resulting from ongoing contingency operations in Southwest Asia and
    Kosovo, as well as other urgent high priority military readiness matters.” Id. at
    75. Specifically, the conferees agreed to provide $5,007,300,000 “ for the ‘Over­
    seas Contingency Operations Transfer Fund’ for costs relating to Operation Allied
    Force and related NATO activities concerning Kosovo, and operations in South­
    west Asia. Of this amount, $3,907,300,000 is provided for personnel and oper­
    ations costs stemming from these operations. An additional $1,100,000,000 is pro­
    vided on a contingent emergency basis to meet expected munitions and readiness-
    related Kosovo expenses, and will be made available only to the extent funds
    are requested in a subsequent budget request by the President.” Id. at 76. The
    conferees further agreed to appropriate $984,300,000 for munitions procurement
    “ associated with operations in Kosovo and Southwest Asia,” id., and $16,469,000
    “ for additional military personnel pay and allowances in support of contingency
    operations in Southwest Asia,” id. They also agreed to appropriate $475,000,000
    “ to be used for construction of mission, readiness and force protection items in
    relation to the conflict in the Balkans, and other contingencies throughout the
    region.” Id. at 81. Finally, the conferees appropriated over $1 billion for Kosovo
    humanitarian assistance, including $149,200,000 for “ humanitarian food aid in
    the Balkans and other regions of need,” id. at 74, $105,000,000 “ for assistance
    for Albania, Macedonia, Bulgaria, Bosnia-Herzegovina, Montenegro, and
    Romania, and for investigations and related activities in Kosovo and in adjacent
    entities and countries regarding war crimes,” id. at 79, and $100,000,000 “ for
    costs related to assisting in the temporary resettlement of displaced Kosovar Alba­
    nians,” id. at 81.
    The House debated H.R. 1141 on May 18 and passed the bill by a 269-158
    vote on the same day. See 145 Cong. Rec. H3269 (daily ed. May 18, 1999).
    The Senate debated the bill on May 20 and passed it by a 64—36 vote on the
    same day. See 145 Cong. Rec. S5682 (daily ed. May 20, 1999).
    The bill signed by the President, entitled “ [a]n Act [mjaking emergency supple­
    mental appropriations for the fiscal year ending September 30, 1999, and for other
    349
    Opinions o f the Office o f Legal Counsel in Volume 24
    purposes,” appropriated well over $5 billion to fund efforts in Kosovo. The prin­
    cipal provision concerning funding, found in Chapter 3 of Title II of the bill (the
    Title entitled “ Emergency National Security Supplemental Appropriations” ),
    reads as follows:
    OPERATION AND MAINTENANCE
    Overseas Contingency Operations Transfer Fund
    (Including Transfer of Funds)
    For an additional amount for “ Overseas Contingency Operations
    Transfer Fund” , $5,007,300,000, to remain available until
    expended: Provided, That the entire amount made available under
    this heading is designated by the Congress as an emergency require­
    ment pursuant to section 251(b)(2)(A) of the Balanced Budget and
    Emergency Deficit Control Act of 1985, as amended: Provided fu r­
    ther, That of such amount, $1,100,000,000 shall be available only
    to the extent that the President transmits to the Congress an official
    budget request for a specific dollar amou nt . . . .
    113 Stat. at 76-77. Another section o f Chapter 3 appropriates $300,000,000
    to remain available for obligation until September 30, 2000 . . .
    only for the accelerated acquisition and deployment of military
    technologies and systems needed f o r the conduct o f Operation
    A llied Force, or to provide accelerated acquisition and deployment
    of military technologies and systems as substitute or replacement
    systems for other United States regional commands which have had
    assets diverted as a result of Operation Allied Force.
    Id. at 78 (emphasis added). The other relevant appropriations discussed in the
    Conference Report are found in various Chapters of Title II of the bill. See, e.g.,
    Chapter 1 (food assistance); Chapter 3 (personnel, procurement); Chapter 4
    (humanitarian assistance); Chapter 5 (resettlement); Chapter 6 (construction).28
    Finally, section 2006 of the bill provides as follows:
    Sec. 2006. (a) Not more than 30 days after the date of the enact­
    ment of this Act, the President shall transmit to Congress a report,
    28 For exam ple, Chapter Four o f the bill provides “ [f]or an additional amount for ‘Economic Support Fund,’
    $105,000,000, to remain available until September 30, 2000, for assistance for Albania, Macedonia, Bosnia-
    H erzegovina, Bulgaria, Montengro, and Romania, and for investigations and related activities in Kosovo and in
    adjacent entities and countries regarding war c rim e s ” 113 Stat. at 84. Chapter Five provides ” [f]or an additional

    (b) OPERATION ALLIED FORCE. — In this section, the term
    “ Operation Allied Force” means operations of the North Atlantic
    Treaty Organization (NATO) conducted against the Federal
    Republic of Yugoslavia (Serbia and Montengro) during the period
    beginning on March 24, 1999, and ending on such date as NATO
    may designate, to resolve the conflict with respect to Kosovo.
    113 Stat. at 80.
    Pub. L. No. 106-31 specifically appropriated over $5 billion to fund continuing
    hostilities in Kosovo, but it did not make specific reference to the WPR.29 The
    W PR’s 60 day clock ran on May 25, four days after the President signed Pub.
    L. No. 106-31.30
    As will be shown in greater detail in the following subparts, the congressional
    debates and the text of Pub. L. No. 106-31 make clear that Congress was
    unquestionably aware that it was funding the hostilities in Kosovo. Moreover, the
    appropriations bill was specifically targeted in substantial degree to the President’s
    request for funds to continue the military action in Kosovo. Congress, in other
    words, used its constitutional authority to appropriate funds to allow the President
    to continue hostilities in the Federal Republic of Yugoslavia. In light of the nature
    of the bill and the historical precedent, discussed above, for Congress to authorize
    hostilities through appropriations measures, Pub. L. No. 106-31 would, in the
    absence of the WPR, have constituted constitutionally adequate authorization for
    continued bombing in the region.
    2. Text
    On its face, H.R. 1664 provided authorization, in the form of an appropriations
    measure, for continuing military operations — or, more specifically, for continuing
    United States participation in the NATO air campaign — in Kosovo. The bill itself
    was entitled “ [a]n Act Making emergency supplemental appropriations fo r mili­
    tary operations, refugee relief, and humanitarian assistance relating to the conflict
    in K osovo ” (emphasis added). In bearing that title, H.R. 1664 plainly indicated
    the main purpose for which the appropriated funds would be spent. Although H.R.
    29 In this respect, Pub. L No. 106-31 differs from sections 2 and 6 o f the Multinational Force in Lebanon Resolu­
    tion, 97 Stat. at 805, and from section 2(c)(1) o f the Authorization for Use of Military Force Against Iraq Resolution,
    105 Stat. at 4, both o f which referred back to section 5(b) of the W PR See supra note 7
    30 A lthough neither the distnct court nor the Court o f Appeals addressed the merits of the suit brought against
    the President by 31 Members o f Congress, see supra p. 328, D istnct Court Judge Friedman did observe in dicta
    that Pub. L No. 106-31 did not constitute an “ authorization” within the meaning of the W PR See Campbell,
    52 F Supp.2d at 44 n 9 ( “ W hile neither the d efeat of the House concurrent resolution nor the passage of the Appro­
    priations Act constitutes an ‘authorization’ within the meaning o f the W ar Powers Resolution, see 50 U S.C. § 1547,
    congressional action on those measures is relevant to the legislative standing analysis.” ) For reasons described
    in this opinion, w e conclude that the appropriation did constitute authorization to continue Operation Allied Force,
    regardless o f whether Congress complied with the legislative requirements specified by an earlier Congress in the
    W PR
    352
    Authorization fo r Continuing Hostilities in Kosovo
    1141 did not bear a title explicitly referencing the conflict in Kosovo, its title
    (indicating that it was a “ emergency supplemental appropriation]” ) as well as
    its direct connection to H.R. 1664, made it clear that it too was substantially,
    if not primarily, concerned with funding the ongoing military effort in Kosovo.
    Furthermore, particular provisions of the appropriation statute underscore that
    Congress, in enacting the appropriation, authorized the President to continue mili­
    tary operations in Kosovo for an indeterminate period, but at least to the end
    of Fiscal Year 1999.31 For example, section 2006(b) defines the phrase “ Oper­
    ation Allied Force” as the “ operations of the North Atlantic Treaty Organization
    (NATO) conducted against the Federal Republic of Yugoslavia (Serbia and Mon­
    tenegro) during the period beginning on March 24, 1999, and ending on such
    date as NATO may designate, to resolve the conflict with respect to Kosovo.”
    113 Stat. at 80. Moreover, section 2006(a) requires that the President, “[n]ot more
    than 30 days after the enactment o f this Act, . . . transmit to Congress a report
    . . . on current United States participation in Operation Allied Force.” Id.
    (emphasis added). The report is to include a statement of national security objec­
    tives involved in Operation Allied Force, § 2006(a)(1), as well as information
    regarding additional planned deployment of certain active duty units to support
    Allied Force between the date of enactment and the end of fiscal year 1999,
    § 2006(a)(3), additional planned reserve component mobilization, including spe­
    cific units to be called up between the date of enactment and the end of fiscal
    year 1999 to support Allied Force, § 2006(a)(4), and any significant revisions to
    the total cost estimate for the deployment of U.S. forces involved in Allied Force
    through the end of fiscal year 1999, § 2006(a)(7).32
    These reporting requirements make sense only on the assumption that the Presi­
    dent was authorized to continue United States participation in Operation Allied
    Force for at least thirty days after the enactment of Pub. L. No. 106-31, a period
    that necessarily extended beyond May 25, when the 60 day “ clock” had expired.
    Indeed, the reporting requirements assume that the President could deploy addi­
    tional active duty units in support of Operation Allied Force, and could mobilize
    reserves to that end, at various times between the enactment of the bill and the
    end o f Fiscal Year 1 9 9 9 — a period that again extended well beyond the 60 day
    “ clock.” Finally, section 2006(a)(7) signaled that Congress wished to keep
    informed of the estimated costs of deploying United States forces in Operation
    Allied Force through the end of the fiscal year. Taken together, these provisions
    show that Members of Congress foresaw the possibility that the President would
    31 We note that Chapter 3 o f Title II, which substantially met the Administration’s request for supplemental funding
    for the Kosovo operation, appropnates $5,007,300,000 “ to remain available until expended.” 113 Stat at 76 Thus,
    these funds were to remain legally available for expenditure even after the end o f Fiscal Year 1999. Id Insofar
    as Congress authorized the continuation of hostilities by providing these funds, it therefore did not sunset that
    authorization on September 30, 1999
    32 Id. We have been informed that the President submitted this report to Congress on August 19, 1999
    353
    Opinions o f the Office o f Legal Counsel in Volume 24
    continue the deployment after May 25, and that they were prepared to fund contin­
    ued military hostilities through at least the end of Fiscal Year 1999.33
    More generally, Pub. L. No. 106-31 m et the President’s request for emergency
    supplemental funding for the very explicit purpose of continuing military oper­
    ations in Serbia and Kosovo. The obvious and stated purpose of the Administration
    in seeking this supplemental funding was to meet anticipated expenses of the cam­
    paign, including any expenses that would be incurred for operations after May
    25. In furnishing such funds, Congress clearly endorsed and authorized the
    Administration’s plans. Indeed, specific line items in the bill demonstrate
    Congress’s belief that Operation Allied Force could continue after May 25. For
    example, Chapter 3, dealing in part with procurement, appropriated $300 million
    “ to remain available for obligation until September 30, 2000 . . . only for the
    accelerated acquisition and deployment of military technologies and systems
    needed f o r the conduct o f Operation Allied Force, or to provide accelerated
    acquisition and deployment of military technologies and systems as [a] substitute
    or replacement systems for other United States regional commands which have
    had assets diverted as a result of Operation Allied Force.” 
    113 Stat. 78
     (emphasis
    added). Again, the funding of “ accelerated acquisition and deployment” of mili­
    tary technologies “ needed for the conduct of Operation Allied Force” unquestion­
    ably assumed that that need might exist, and could lawfully be met, after May
    25. 
    Id.
    Furthermore, both H.R. 1141 and H.R. 1664 were plainly identified as emer­
    gency, supplem ental appropriations. Thus, Congress was well aware that the bill
    was an extraordinary measure, wholly outside the routine budget process for the
    regular funding of Department of Defense activities. This was free-standing and
    widely publicized legislation, introduced soon after several major Congressional
    debates on the Administration’s policy, for the explicit purpose of funding con­
    tinuing military operations in Kosovo. Congress decided to fund that operation.
    3. Legislative History
    The legislative history of Pub. L. No. 106-31 strongly confirms this under­
    standing of the bill’s intent and effect. This part analyzes that history in four
    stages: (a) Secretary of Defense William S. Cohen’s explanation of the Adminis­
    tration’s request for emergency supplemental funding made on April 21, 1999,
    to the Defense Subcommittee of the House Appropriations Committee; (b) the
    House Appropriations Committee’s consideration of H.R. 1664; (c) the first House
    33 Indeed, the House Appropriations Committee Report states that “ [t]he Committee recognizes that the specific
    budget estimates underlying the supplemental requests for Kosovo operations may require adjustments due to the
    evolvtng nature o f the air campaign, changes in deployment schedules and operational tempo, and other requirements
    associated with current operations and currently planned forces which were not identified at the time the supplemental
    request was developed.” H.R. Rep. No 106-125, at 4 (1999)
    354
    Authorization fo r Continuing Hostilities in Kosovo
    floor debate on H.R. 1664 on May 6, 1999; and (d) the final House and Senate
    votes on H.R. 1141 on May 18 and 20, 1999, respectively.
    a. Secretary Cohen's Testimony
    The Administration’s statement to Congress of the purposes of seeking the
    supplemental appropriation weigh heavily in favor of construing Pub. L. No. 106-
    31 as an authorization to continue Operation Allied Force beyond the May 25
    cutoff.34 Of particular importance is Secretary of Defense William S. Cohen’s
    testimony at an April 21, 1999 hearing by the Subcommittee on Defense of the
    House Committee on Appropriations, in support of the Administration’s request
    for the supplemental appropriation. See Department o f Defense Appropriations fo r
    2000: Hearings Before the Defense Subcomm. o f the House Comm, on Appropria­
    tions, 106th Cong. 288 (1999) (Statement of William S. Cohen, Secretary of
    Defense). Secretary Cohen made plain the Administration’s intent to use the pro­
    posed funding to go forward with Operation Allied Force, if necessary for a pro­
    longed period. He stated:
    This is an emergency, non-offset supplemental totaling $6.05 bil­
    lion: $5,458 billion for DoD and $591 million for the State Depart­
    ment and international assistance programs. The DoD portion of
    the supplemental has these major components:
    Kosovo Military Operations ($3.3 billion). The request funds pro­
    jected force levels and the current high operating tempo through
    the end of the fiscal year. All U.S. forces that have been deployed
    or ordered to deploy are assumed to remain in theater and operate
    at current sortie and strike levels. The request does not fund pos­
    sible deployment of U.S. ground forces to Kosovo or peacekeeping
    operations or reconstruction there.
    NATO is engaged in a serious military effort in Kosovo. It will
    not be quick, easy, or neat. We have to be prepared for the possi­
    bility of casualties among NATO forces. But we cannot falter, and
    we will not fail.
    Id. 291-92.
    34 We note also lhat the President advised Congress that “ [i]t is not possible to predict how long either of these
    operations [air strikes and relief efforts] will continue. The duration o f the deployments depend[s] upon the course
    o f events in Kosovo . . .      Letter for Congressional Leaders Reporting on Airstnkes Against Serbian Targets in

    355
    Opinions o f the Office o f Legal Counsel in Volume 24
    Secretary Cohen’s statements plainly advised Congress of the Administration’s
    determination to pursue military operations, if necessary, for an indefinite period
    beyond May 25, and he specifically requested Congress to fund such operations
    at least “ through the end of the fiscal year.” 35
    b. House Appropriations Committee Action
    Shortly before the House Appropriations Committee considered H.R. 1664 on
    April 29, Representative William Young, the Chairman of the Committee, stated
    that “ [t]his $12.9 billion bill recognizes that we are more deeply involved in
    Kosovo than we were led to believe and that unless [President] Milosevic has
    a major change of heart, our involvement will be deeper than originally antici­
    pated.” Chairman Young Announces Kosovo Emergency Supplemental Bill,
    www.house.gov/appropriations/news/106-l/pr00kosovo.html (Apr. 27, 1999).
    During the mark-up itself, Congressman Young said, “ I’m not sure what message
    [Milosevic] got from that [the House’s April 28 votes on authorizing military
    action], but I can guarantee you when we pass this bill today, there will be no
    doubt in the mind of Mr. Milosevic where we stand; that this Congress stands
    behind our troops no matter where they are or what they’re doing. And we’re
    going to provide them with what they need to accomplish their mission . . . .”

    Also during the mark-up, Congressman Obey clearly explained the Administra­
    tion’s purpose in seeking the emergency appropriation, and the length of the oper­
    ations it was intended to fund. He said:
    Now let me explain what it is we’re doing.
    In the administration’s request for DOD, they asked for $5.5 billion
    for military operations. To reimburse them for previous costs in
    Iraq they asked for $272 million, and in Kosovo they asked for

    the $6 billion as sufficient to fund through September the operations of an intensified air campaign, to replenish

    36 Other Members o f Congress made similar statements before the House floor debate on the bill For example,
    according to press reports. Congressman David Dreier, the Chairman o f the House Rules Committee (which framed
    the rules for the debate over H R 1664), expressed the view that “ President Clinton is acting within his authonty

    c. The House May 6 Floor Debate
    The floor debate on H.R. 1664 on May 6 also demonstrates that the House
    clearly understood that it was funding military operations that could well continue
    for months after May 25. At the start of that debate, Congressman Obey stated
    squarely that
    [t]he administration has asked about $6 billion to cover the cost
    of this war, plus they have asked for humanitarian assistance. The
    amount that they have requested will pay for an 800-plane war,
    24 hours a day bombing of virtually every target in Yugoslavia
    that one could imagine anywhere. That will be sustained on a daily
    basis through the end o f the fiscal year.

    Congressman Young, also speaking at the start of the debate, discounted the
    April 28 House votes on the Kosovo operation as “ votes that gave Members an
    opportunity to voice their opinion in resolutions that were not truly binding,”
    and argued that the vote on H.R. 1664 “ is the real message. This is a message
    to Milosevic that we are serious. This is a message to our troops that we are
    serious in providing them with what they need to accomplish their mission and
    to give themselves a little protection while they are at it.”

    on the War Powers Act showed that Congress was of many minds on the policy
    issue, but this debate today is not about policy. . . . It is about money.” ). Speaker
    Hastert likewise emphasized the need to support troops in action, stating that
    “ [l]ast week, the House spoke on the President’s policies concerning the engage­
    ment in Kosovo; and, [c]learly, the House had some misgivings about those poli­

    its soldiers, sailors, and airmen as they defend America.” 
    Id.
     at H2822.
    Some Members specifically argued that funding was necessary to continue
    Operation Allied Force. Congressman Dreier maintained that “ the price of failure
    in Kosovo is simply too great at this point. . . . Congress must ensure that the
    resources are available to carry out that strategy.” 
    Id.
     at H2821. Congressman
    Skelton said that the appropriation “ ensures that our military has more than ade­
    quate resources to carry out the Kosovo air campaign.” 
    Id.
     at H2829. Congress­
    man Knollenberg stated that, while he had “ strong reservations about the decisions
    that have led us to this point,” he “ believe[d] it is important . . . that NATO
    continue its operation.” 
    Id.
     at H2833. Congressman Gilman interpreted passage
    of the appropriation as showing that “ we are fully supportive of what our military
    is doing at the present time in Kosovo.” 
    Id.
     at H2834 (remarks of Cong. Gilman).
    Opponents of the bill also saw it as authorizing continuing operations in Kosovo.
    Congressman Stark specifically noted that “ [appropriating defense funds for the
    attack on Yugoslavia gives the President the authorization needed under the War
    Powers Act to continue the air strikes and allow[s] him to use ground troops
    if necessary. However, if funds were withheld, the President would be required
    to remove the troops from their current mission by May 25, 1999.” 
    Id.
     at H2839.
    Congressman Paul, another opponent, stated that “ [f]unding is an endorsement
    of the war. We must realize that it is equivalent to it. We have not declared
    this war. If we fund it, we essentially become partners to this ill-advised war.”

    d. House and Senate Consideration o f Final Bill
    In addition to the numerous explicit references to the Kosovo conflict contained
    in the joint conference report described above, the floor debates on the final
    version of H.R. 1141 also demonstrate that Congress intended to enable the Presi­
    dent to continue the campaign for an indefinite period after the W PR’s 60 day
    ‘‘clock’’ had run.
    (i)
    As he had done in the May 6 debate, Congressman Young again explained
    to the House the significance of the appropriation for the campaign in Kosovo:
    A no vote will be sending a message to Milosevic that we are not
    really serious about bringing him to heel. He does not need to get
    that message, he has got enough problems already. A no vote will
    be against those soldiers and sailors and airmen and marines and

    coastguardsmen who are involved in this conflagration, or war
    145 Cong. Rec. H3263 (daily ed. May 18, 1999).
    Congressman Lewis was no less clear and emphatic:
    This bill is committed to funding our effort in Kosovo . . . . As
    we move into the months ahead, none of us can predict what the
    cost might be. But this bill is a reflection of the fact that the House
    wants to make sure that adequate funding is present no matter how
    long the war may extend itself. . . .
    I must say, Mr. Speaker, one of the messages we are sending here
    to our troops that is especially important involves the advanced
    funding of pay adjustments for the troops. That essentially tells
    them in clear terms that the House is not only supporting their effort
    in Kosovo, but intends to continue to support their service for the
    country as long as it might continue in the months and the years
    ahead.
    
    Id.
     at H3256.
    Other speakers stressed the need to fund the NATO mission in Kosovo. Con­
    gressman Dreier found the bill “ absolutely necessary to offset the very significant
    costs of the Kosovo campaign. . . . [I]t is now a very clear national interest that
    both the United States of America and the North Atlantic Treaty Organization
    alliance prevail in this conflict.” 
    Id.
     at H3232-33. Congressman Levin argued
    that “ [t]he House should move quickly to approve the urgently needed funding
    to continue NATO’s military operations against Slobodan Milosevic’s forces in
    Kosovo.” 
    Id.
     at H3263. Congressman Bliley said that the bill would “ support
    NATO so that we can bring the conflict in Kosovo to a speedy and successful
    conclusion.” 
    Id.
     at H3267.
    As in the May 6 debate, other House members emphasized the need to support
    troops in combat. Congressman Regula stated that “ the purpose of this bill is
    to support our troops overseas.” 
    Id.
     at H3257. Congressman Packard said that
    “ H.R. 1141 supports America’s troops, and regardless of whether you agree with
    the policies of this Administration, we can’t afford to neglect the needs of those
    who must carry them out.” 
    Id.
     at H3259. Congressman Weygand voted for the
    bill “ because I believe it is absolutely necessary to provide our troops with the
    tools and support they need to complete their mission.” 
    Id.
     at H3264.
    Opponents of the bill also repeated their warnings that the bill would allow
    the continuation of hostilities. Congressman Kucinich thought that the bill “ con­
    tains provisions that will enable the prosecution of a wide war against the Federal
    359
    Opinions o f the Office o f Legal Counsel in Volume 24
    Republic of Yugoslavia, even though Congress has expressly voted not to declare
    war.” 
    Id.
     at H3226. Congressman Paul said, “ the real principle here today that
    we are voting on is whether or not we are going to fund an illegal, unconstitutional
    war. It does not follow the rules of o u r Constitution. It does not follow the rules
    of the United Nations Treaty. It does not follow the NATO Treaty. And here
    we are just permitting it, endorsing it but further funding it.” 
    Id.
     at H3228.

    The Senate debated H.R. 1141 tw o days after the House vote. The Senate’s
    consideration of the Kosovo appropriation was much less extensive than the
    House’s. As Senator Byrd observed on May 20, 1999 — the day H.R. 1141 was
    debated and voted on in the Senate— “ [T]he first time the Kosovo funding has
    been before the Senate is today in the form of this conference agreement on H.R.
    1141.” 145 Cong. Rec. S5646 (daily ed. May 20, 1999).37
    Although most of the speakers in the Senate debate focused on other aspects
    of the bill, an opponent, Senator Fitzgerald, spelled out very precisely the effect
    that passage of the appropriation would have on the issue of war powers:
    [I]n the past, American presidents have argued that a congressional
    appropriation for U.S. military action abroad constitutes a congres­
    sional authorization for the military action. I will not vote for an
    authorization of money that may be construed as authorizing, or
    encouraging the expansion of, the President’s military operations
    in Kosovo. I will oppose the appropriation of almost $11 billion
    for a war I have consistently spoken out against.
    145 Cong. Rec. S5665 (daily ed. M ay 20, 1999).38
    37 The Senate was aware, well before the floor debate on H R. 1141, of the effect of the WPR on its deliberations
    over Kosovo. Earlier in the session. Senator McCain had introduced a measure, S.J. Res 20, to authonze the President
    to use “ all necessary force” to achieve the goals o f Operation Allied Force. Id at 2. Although the Senate had
    at first seemed unlikely to take up that measure, “ Senate Parliamentanan Bob Dove announced April 28 .           that
    the resolution fit the critena for tnggenng the W ar Powers Resolution, even though it was not designed with that
    in m ind.” Pat Towell, Congress Set To Provide Money, But No Guidance, fo r Kosovo Mission, C.Q. Weekly, May
    I, 1999, at 1037. W hen the Senate debated S.J. Res 20 on M ay 3, 1999, Senator Feingold drew attention to the
    fact that the measure “ has been determined to be pnvileged under the terms of . . the War Powers Resolution,”
    and emphasized that “ [n]ot only must [the W PR] be taken seriously, but because of the appropnate ruling of the
    Parliam entanan . . , it is being taken seriously.” 145 Cong. Rec S4525 (daily ed May 3, 1999) (remarks of Sen
    Feingold). Further, he added that before the Parliam entanan’s ruling, “ many people did not realize for a while,
    that the W ar Powers Resolution and its clock w ere ticking " I d S J. Res. 20 was tabled by the Senate by a 7 8 -
    22 vote on M ay 4, 1999. 145 Cong. Rec. S4616 (daily ed M ay 4, 1999) Later, the Senate passed a concurrent
    resolution authorizing the President to conduct military air operations and missile stnkes in cooperation with our
    NATO allies against the Federal Republic of Yugoslavia. See supra note 2 6 .
    38 Senator G orton, another opponent of the bill, also objected that it would “ pay for the costs o f the war in
    the Balkans.” Id. at S5650
    360
    Authorization fo r Continuing Hostilities in Kosovo
    Speaking immediately after Senator Fitzgerald, Senator Dodd, a supporter of
    the bill, explained that the appropriation would indeed support the continuation
    of military action:
    The original intent of the President’s request for emergency appro­
    priations from Congress was to provide our men and women in
    uniform with the equipment and materiel they need to effectively
    strike the Yugoslav military. While I am heartened by recent reports
    of a possible diplomatic solution, we must remain prepared to con­
    tinue our military efforts in the absence of an enforceable diplo­
    matic solution which meets NATO’s conditions.
    Our military, however, cannot effectively combat this evil if we
    in the Congress fail to offer them our support. One month ago,
    President Clinton sent a request to Congress for $6 billion in order
    to fund our military operations through the end o f the fiscal year.
    That money is included in this bill.
    Id. at S5666 (emphasis added).
    Senator Stevens, the Chairman of the Senate Appropriations Committee,
    asserted that the funding was intended to provide for military operations in Kosovo
    through the remainder of the calendar (not merely fiscal) year:
    Hopefully we will not have to see another emcrgcncy supplemental
    with regard to the conduct of the Kosovo operation during the
    period of time we will be working on the regular appropriations
    bills for the year 2000. In effect, we have reached across and gone
    in — probably this bill should be able to carry us, at the very least
    to the end of this current calendar year. The initial requests of the
    President took us to the end of the fiscal year on September 30.
    Id. at S5644.
    As in the House debate, several speakers voiced the need to support troops
    in ongoing combat. For example, Senator Warner said, “ I support this bill for
    one simple reason — we are at war. As we speak, we have military forces engaged
    in combat — going in harm’s way — in the skies over the Balkans and Iraq.
    Whether or not there is agreement on how these risk-taking operations are being
    prosecuted is not now the question. We must support our military forces who
    are risking their lives daily to carry out the missions they have been assigned.”

    Opinions o f the Office o f Legal Counsel in Volume 24
    V. Pub. L. No. 106-31 and the War Pow ers Resolution
    As described in the preceding section, the text of Pub. L. No. 106-31 and the
    legislative record as a whole make clear that Congress intended, by enacting the
    President’s request, to enable the President to continue U.S. participation in Oper­
    ation Allied Force for as long as funding remained available, i.e., through at least
    the end of the fiscal year on September 30, and indeed even longer.39 Congress
    was repeatedly advised of this effect by its own Members (both supporters and
    opponents o f continuing the operation) and by Administration witnesses. For at
    least the month that the Administration’s request was pending, and at a time when
    the duration of hostilities was uncertain, Congress was aware that a vote for the
    bill would be a vote to authorize the campaign.40
    In this context, the concerns that have been voiced about finding congressional
    authorization in general appropriation statutes are not applicable. The purposes
    of both H.R. 1664 and H.R. 1141 were plain on the face of the bills. Nor was
    this a case in which the Committees with jurisdiction over war powers “ would
    [have been] somewhat surprised to learn that their careful work on the substantive
    legislation had been undone by the simple- and brief-insertion of some inconsistent
    language in Appropriations Committees’ Reports.” Hill, 
    437 U.S. at 191
     (rejecting
    Authority’s argument that a series of appropriations funding the Tellico Dam
    Project constituted an implied repeal of the Endangered Species Act). In this case,
    “ Congress as a whole was aware o f ’ the basic terms of the special, emergency
    appropriation for continuing military operations in Kosovo. 
    Id. at 192
    . The bill
    was surely among the most visible and important pieces of legislation introduced
    39 As noted above, the core appropriation of som e $5 billion was “ available until expended.” 113 Stat at 7 6 -
    77 In other words, it was a “ no-year” appropriation that remained legally available even after September 30.
    40 In reaching this conclusion, we need not and do not decide that the appropriation authonzed the introduction
    of United States Forces onto the ground in Serbia or Kosovo Interpretation of Pub. L No 106-31 must take into
    account the House o f Representatives’ vote on April 28 to block funding for ground troops without additional specific
    authorization from Congress, the President’s Letter to the Speaker o f the House of Representatives of April 28,
    1999, agreeing not to deploy ground troops in a “ non-permissive environment” without first “ ask[ing] for Congres­
    sional support,"s e e 145 Cong Rec. H2883 (daily ed. May 6, 1999) (reprinting letter); see also 145 Cong. Rec.
    H2405 (daily ed Apr. 28, 1999) (remarks of C ong Gephardt, explaining President’s representations), 145 Cong
    Rec S4531 (daily ed. May 3, 1999) (reprinting sim ilar letter o f April 28, 1999, to Senate Majority Leader); Chairman
    Y oung’s statem ent that “ [tjhere is nothing in [H.R 1664] that would authonze any money to be used to deploy
    ground troops into Kosovo,” 145 Cong. Rec H2882 (daily ed. May 6, 1999); Congressman Lewis’s statement dunng
    the House A ppropnations C om m ittee’s mark-up that “ not a dime o f these funds will be spent for troops being
    placed in K osovo,” Transcnpt at 10; and Secretary Cohen’s statement o f Apnl 21 that the supplemental appropriation
    will not fund the introduction o f ground troops to Kosovo. Moreover, on May 25, 1999, Senator Warner, speaking
    in opposition to a proposed rider to S. 1059, 106th Cong (1999), the Department of Defense authonzation bill
    for Fiscal Y ear 2000 that would have required Congressional authorization before United Slates ground troops could
    be deployed in Yugoslavia, stated that, on that day, the Secretaries o f State and Defense and the National Security
    Adviser, in a meettng with Senators, had “ said without any equivocation whatsoever that the President would for­
    mally com e to the Congress and seek legislation” before deploying ground troops 145 Cong. Rec. S5939 (daily
    ed M ay 25, 1999) In light o f those actions and statements, which o f course were closely contemporaneous with
    Congressional consideration o f H.R. 1664 and H.R. 1141, it is unlikely that Congress intended to provide authoriza­
    tion for the introduction o f ground troops into Serbia or Kosovo by enacting this appropriation. We note, however,
    that the House voted on M ay 6 to reject an amendment, proposed by Congressman Istook, to ban the use of the
    supplemental appropriation to fund the deployment o f ground troops into Yugoslavia, “ except in time of w ar.”

    Authorization fo r Continuing Hostilities in Kosovo
    before the first session of the 106th Congress, and both the Administration and
    individual members pointedly and publicly underscored its significance. Finally,
    unlike, for example, the Tellico Dam appropriations involved in Hill, which “ rep­
    resented relatively minor components of the lump-sum amounts” of the
    Authority’s entire budget, H.R. 1141 was a freestanding bill that, in the form
    in which it was presented by the Administration, focused narrowly on military
    spending for Operation Allied Force. 
    Id. at 189
    .41 In sum, H.R. 1141 was intended
    to enable the President to continue Operation Allied Force, and to furnish him
    with the necessary funds for doing so, even if that operation were not brought
    to a successful conclusion by May 25. Pub. L. No. 106-31 is thus analytically
    similar to earlier congressional appropriation statutes, discussed in Section II, that
    authorized executive branch action (including the statutes that played a role in
    authorizing conflict).
    The House’s votes on the four other Kosovo-related measures on April 28 do
    not lead us to change our conclusion. See supra pp. 348-49. Although the House
    did defeat the resolution declaring a state of war between the United States and
    Serbia and passed a resolution blocking funding for ground troops without addi­
    tional specific authorization, it also defeated a resolution that would have directed
    the President to remove the Armed Forces from the region and tied on the resolu­
    tion that would have specifically authorized the President to conduct military air
    operations against Serbia. The message of all these votes is ambiguous. The only
    clear message that Congress sent regarding the continuation of military operations
    in Serbia is Pub. L. No. 106-31, which appropriated over $5 billion to continue
    these operations. As we have already explained, this was sufficient to constitute
    specific authorization within the meaning of the WPR.
    Moreover, the argument, explained earlier, see supra p. 338-39, and invoked
    by Judge Randolph in his concurrence in C am pbell*2 that appropriation statutes
    should not be understood as authorizing hostilities because they might just as
    easily be intended to protect troops already committed, carries little weight here.
    We recognize that a number of statements made by Members of Congress {e.g.,
    Senator Warner, Congressman Weygand) indicate an intention to “ support”
    already committed troops. These isolated statements, however, do not demonstrate
    that Congress did not intend to authorize continuing hostilities. The United States
    did not have ground troops in combat in Serbia or Kosovo at the time Pub. L.
    No. 106-31 was enacted, but rather was engaged in an air campaign in which
    U.S. forces were in harm’s way only for the length of each sortie flown. If Con­
    41 Although Pub L. No 106-31 o f course ended up making a range of appropriations m addition to those for
    the Kosovo effort, the legislative history makes clear that the b ill’s central, overriding purpose was to fund the
    hostilities in Yugoslavia.
    42See Campbell, 203 F 3 d at 31 n.10 (Randolph, J , concum ng) ( “ The majority attaches some importance to
    Congress’s decision to authonze funding for Operation Allied Force and argues that Congress could have denied
    funding if it wished to end the war However, in M itchell v Laird         we held that, as ‘every schoolboy know s,’
    Congress may pass such legislation, not because it is in favor o f continuing the hostilities, but because it does
    not want to endanger soldiers in the field The War Powers Resolution itself makes the same point ” )

    Opinions o f the Office o f Legal Counsel in Volume 24
    gress did not intend to authorize continuing hostilities, but instead intended only
    to protect previously deployed troops, it could have, and most likely would have,
    styled its rejection of authorization for continuing hostilities by either phasing out
    appropriated funds over time, as it did in the case of Somalia, or by prohibiting
    the use of funds for certain purposes, as it did with the Cooper-Church amend­
    ment. Here, Congress chose neither option. Instead, it appropriated funds “ until
    expended” without placing any limitations on the use of those funds. The actual
    steps taken by Congress demonstrate that it intended to authorize the President
    to continue hostilities, and, in particular, to continue the air campaign. See Berk,
    
    317 F. Supp. at 724
     (noting that even though some Members of Congress stated
    that “ their votes for the appropriation did not constitute approval of an undeclared
    war [in Vietnam],” nonetheless the appropriation “ gave Congressional approval
    to military expenditures in Southeast Asia” ); 
    id. at 728
     (finding that the “ dis­
    claimers by individual Congressmen of any approval of the Vietnam conflict”
    could only “ ‘disclose the motive and could not disprove the fact of authoriza­
    tion’ ” (citation omitted)). In light o f Congress’s possible alternatives, reading the
    statements at issue as indicating an intent to protect already deployed troops
    simply “ doesn’t make sense.” Ely, supra, at 129. It is more reasonable to interpret
    those statements as indicating an intent to “ support” American troops by author­
    izing the President to continue hostilities so those troops would be able to com­
    plete their missions successfully.
    Section 8(a)(1) does not lead to a contrary conclusion. As discussed above,
    that section cannot constitutionally be read to take from Congress a mechanism
    for authorizing war permitted by the Constitution. Instead, it has the effect of
    establishing a background principle against which Congress legislates. Section
    8(a)(1) means, then, that it cannot be “ inferred” — to quote the language of the
    provision — that Congress has authorized the continuation of conflicts from the
    mere fact that it has enacted an appropriation statute (unless the statute references
    the WPR). Nonetheless, if the text and legislative history of the appropriation
    statute make clear that it was Congress’s clear intent to authorize continued oper­
    ations, that intent is controlling, even if the statute does not reference the WPR.
    Such an appropriation statute is an implied partial repeal of section 8(a)(1) (or
    a supersession of section 8(a)(1)). For reasons already discussed, Pub. L. No. 106-
    31 is such a statute.43
    Finally, it is worth observing that, in this case, the underlying purpose of the
    W PR’s “ clock” was fully satisfied. That clock functions to ensure that, where
    the President commits U.S. troops to hostilities without first obtaining congres­
    43 For all the reasons discussed in this opinion, the maxim discussed above-that the law disfavors implied repeals,
    see supra note 22 — does not apply. This is not a case, for example, in which a Member of Congress would have
    had to “ scrutiniz[e] in detail the [Appropnation] Committee proceedings” to become aware of the discrepancy
    between section 8(a)(1) and Pub. L. No 106-31. Tennessee Valley Authonty, 437 U S at 189 n.35. Indeed, because
    Pub L No 106-31 was among the most prominent pieces o f legislation pending before the 106th Congress, and
    because both the Administration and individual M embers o f Congress strongly and visibly underscored the signifi­
    cance o f the legislation, “ Congress as a whole w as aware o f ’ the basic terms of Pub. L No 106-31 Id at 192
    364
    Authorization fo r Continuing Hostilities in Kosovo
    sional authorization, Congress has the opportunity to consider the merits of the
    President’s actions and to decide whether those hostilities may continue. Here,
    the President ordered a series of air strikes in the Federal Republic of Yugoslavia
    “ to demonstrate the seriousness of NATO’s purpose so that the Serbian leaders
    understand the imperative of reversing course; to deter an even bloodier offensive
    against innocent civilians in Kosovo; and, if necessary, to seriously damage the
    Serbian military’s capacity to harm the people of Kosovo.” Letter for the Speaker
    from the President, 1 Pub. Papers of William J. Clinton at 959. Congress then
    had the opportunity to deliberate on the wisdom of the President’s actions, which
    it did, considering several resolutions relating to the military efforts in Kosovo.
    After all of those deliberations, Congress decided to use one of its most important
    constitutional powers over war and peace — its appropriation power-specifically
    to fund the ongoing military effort. By doing so, it authorized the President to
    continue military activities in the region.
    Conclusion
    Pub. L. No. 106-31 constituted Congressional authorization for continuing
    bombing efforts in Kosovo even after the running of the 60 day clock established
    by section 5(b) of the WPR. Interpreted in light of constitutional concerns, section
    8(a)(1) of the WPR does not lead to an alternative result; properly read, section
    8(a)(1) simply has the effect of establishing a background principle against which
    subsequent Congresses legislate when they enact appropriation statutes. Section
    8(a)(1) creates procedural requirements that subsequent Congresses must follow
    to authorize hostilities. If a subsequent Congress, however, chooses in a particular
    instance to enact legislation that either expressly or by clear implication authorizes
    hostilities, it may decide not to follow the WPR’s procedural requirements. In
    this case, read in light of the background principle established by section 8(a)(1),
    the text and legislative history of Pub. L. No. 106-31 make clear that Congress
    intended to authorize continuing hostilities in the Federal Republic of Yugoslavia.
