§ 1541. Purpose and policy

• (a) 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 collective 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 or in such situations.
• (b) Under article I, section 8, of the Constitution, it is specifically provided that the Congress shall have the power to make all laws necessary and proper for carrying into execution, not only its own powers but also all other powers vested by the Constitution in the Government of the United States, or in any department or officer thereof.
• (c) The constitutional powers of the President as Commander-in-Chief to introduce United States Armed Forces into hostilities, or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, are exercised only pursuant to (1) a declaration of war, (2) specific statutory authorization, or (3) a national emergency created by attack upon the United States, its territories or possessions, or its armed forces.

§ 1542. Consultation; initial and regular consultations

The President in every possible instance shall consult with Congress before introducing United States Armed Forces into hostilities or into situations where imminent involvement in hostilities is clearly indicated by the circumstances, and after every such introduction shall consult regularly with the Congress until United States Armed Forces are no longer engaged in hostilities or have been removed from such situations.

§ 1543. Reporting requirement

• (a) In the absence of a declaration of war, in any case in which United States Armed Forces are introduced—
  • (1) into hostilities or into situations where imminent involvement in hostilities is clearly indicated by the circumstances;
  • (2) into the territory, airspace or waters of a foreign nation, while equipped for combat, except for deployments which relate solely to supply, replacement, repair, or training of such forces; or
  • (3) in numbers which substantially enlarge United States Armed Forces equipped for combat already located in a foreign nation;
    • (A) the circumstances necessitating the introduction of United States Armed Forces;
    • (B) the constitutional and legislative authority under which such introduction took place; and
    • (C) the estimated scope and duration of the hostilities or involvement.
• (b) The President shall provide such other information as the Congress may request in the fulfillment of its constitutional responsibilities with respect to committing the Nation to war and to the use of United States Armed Forces abroad.
• (c) Whenever United States Armed Forces are introduced into hostilities or into any situation described in subsection (a) of this section, the President shall, so long as such armed forces continue to be engaged in such hostilities or situation, report to the Congress periodically on the status of such hostilities or situation as well as on the scope and duration of such hostilities or situation, but in no event shall he report to the Congress less often than once every six months.

§ 1544. Congressional action

• (a) Each report submitted pursuant to section 1543(a)(1) of this title shall be transmitted to the Speaker of the House of Representatives and to the President pro tempore of the Senate on the same calendar day. Each report so transmitted shall be referred to the Committee on Foreign Affairs of the House of Representatives and to the Committee on Foreign Relations of the Senate for appropriate action. If, when the report is transmitted, the Congress has adjourned sine die or has adjourned for any period in excess of three calendar days, the Speaker of the House of Representatives and the President pro tempore of the Senate, if they deem it advisable (or if petitioned by at least 30 percent of the membership of their respective Houses) shall jointly request the President to convene Congress in order that it may consider the report and take appropriate action pursuant to this section.
• (b) 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 period, or (3) is physically unable to meet as a result of an armed attack upon the United States. Such sixty-day period shall be extended for not more than an additional thirty days if the President determines and certifies to the Congress in writing that unavoidable military necessity respecting the safety of United States Armed Forces requires the continued use of such armed forces in the course of bringing about a prompt removal of such forces.
• (c) Notwithstanding subsection (b), at any time that United States Armed Forces are engaged in hostilities outside the territory of the United States, its possessions and territories without a declaration of war or specific statutory authorization, such forces shall be removed by the President if the Congress so directs by concurrent resolution.

§ 1545. Congressional priority procedures for joint resolution or bill

• (a) Any joint resolution or bill introduced pursuant to section 1544(b) of this title at least thirty calendar days before the expiration of the sixty-day period specified in such section shall be referred to the Committee on Foreign Affairs of the House of Representatives or the Committee on Foreign Relations of the Senate, as the case may be, and such committee shall report one such joint resolution or bill, together with its recommendations, not later than twenty-four calendar days before the expiration of the sixty-day period specified in such section, unless such House shall otherwise determine by the yeas and nays.

In the event the conferees are unable to agree within 48 hours, they shall report back to their respective Houses in disagreement.
