Authorization for Use of Military Force 2001

Authorization for Use of Military Force

On September 18, 2001, President Bush signed the Authorization for Use of Military Force (AUMF) into law.[1] Through the AUMF, Congress authorized the President to initiate military operations in response to the September 11 terrorist attacks against the United States. Section 2(a) of the AUMF articulates this express expansion of Executive power, stating that the President is authorized to

“use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons . . .”[2]

Section 2(b) proceeds by providing the “specific statutory authorization within the meaning of section 5(b) of the War Powers Resolution,”[3] which requires the President to obtain congressional authorization for the prolonged deployment and use of United States armed forces.[4]

Soon after the passage of the AUMF, President Bush utilized his enhanced war powers to send troops to Afghanistan and to escalate efforts to combat domestic terrorism.[5] The President additionally invoked the “use of all necessary and appropriate force” language of the AUMF in asserting his authority to indefinitely detain any individual designated as an “enemy combatant” and to try “enemy combatants” before a military commission under rules and procedures promulgated by the Secretary of Defense.[6] In a series of subsequent habeas corpus cases (often referred to as the “Enemy Combatant Cases”), the Supreme Court rejected this assertion of Executive authority. The Court ruled that the President could not indefinitely detain “enemy combatants” without adequate judicial review and that Congress must provide explicit authorization before the President may convene military commissions.[7]
