The War Powers Resolution
Section 3 of the resolution requires presidential consultation with Congress before sending U.S. armed forces into hostilities. Section 4 requires the president to report to Congress within forty‐eight hours after the introduction of U.S. forces into hostilities or imminent hostilities, and every six months thereafter. Section 5 provides that within sixty days after issuing the initial report, the president must receive either a declaration of war or a specific statutory authorization, or else an extension of the sixty‐day period; if Congress refuses, the president has thirty days to remove U.S. forces from hostilities. Section 5 also allowed Congress at any time to direct removal of the forces by concurrent resolution. Since 1983, an amendment has specified that removal of forces is directed by a joint resolution that must be submitted to the president and is subject to presidential veto.
Richard Nixon and all his successors have argued that the law undercuts U.S. credibility with its allies, gives adversaries reason to doubt U.S. determination to use force, and infringes on presidential prerogatives. Presidents have routinely ignored, evaded, or otherwise minimized the reach of the law, and by the end of the Reagan administration, Congress had abandoned it.
Federal courts have indicated their doubts about the constitutionality of many provisions of the law in Crockett v. Reagan, Lowry v. Reagan, Dellums v. Bush, and Ange v. Bush. The effect of these cases, and congressional unwillingness to use the procedures in the act, has essentially nullified it, although there appears to be significant public support for the concept behind it.
