Congressional Authority To Limit U.S. Military Operations in Iraq [February 27, 2008] [open pdf - 330KB]
"This report begins by providing background, discussing constitutional provisions allocating war powers between Congress and the President, and presenting a historical overview of relevant court cases. It discusses Congress's power to rescind prior military authorization, concluding, in light of relevant jurisprudence and the War Powers Resolution, that the repeal of the AUMF, absent the further denial of appropriations or the establishment of a specific deadline for troop withdrawal, would likely have little, if any, legal effect on the continuation of combat operations. The report discusses Congress's ability to limit funding for military operations in Iraq, examining relevant court cases and prior measures taken by Congress to restrict military operations, as well as possible alternative avenues to fund operations if appropriations are cut. There follows a summary of relevant measures included in the vetoed FY2007 supplemental appropriations bill, H.R. 1591, and the enacted act, H.R. 2206. The report provides historical examples of measures that restrict the use of particular personnel, and concludes with a brief analysis of arguments that might be brought to bear on the question of Congress's authority to limit the availability of troops to serve in Iraq. Although not beyond debate, such a restriction appears to be within Congress's authority to allocate resources for military operations."
