A new Congressional Research Service report reviews provisions in the competing versions of the National Defense Authorization Act regarding detainee affairs. Here is a summary of the report’s findings:

Both House and Senate bills competing to become the National Defense Authorization Act of FY2012 contain a subtitle addressing issues related to detainees at the U.S. Naval Station at Guantanamo Bay, Cuba, and more broadly, hostilities against Al Qaeda and other entities. At the heart of both bills’ detainee provisions appears to be an effort to confirm or, as some observers view it, expand the detention authority that Congress implicitly granted the President via the Authorization for Use of Military Force (AUMF, P.L. 107-40) in the aftermath of the terrorist attacks of September 11, 2001.

H.R. 1540, as passed by the House of Representatives on May 26, 2011, contains provisions that would reaffirm the conflict and define its scope; impose specific restrictions on the transfer of any non-citizen wartime detainee into the United States; place stringent conditions on the transfer or release of any Guantanamo detainee to a foreign country; and require that any foreign national who has engaged in an offense related to a terrorist attack be tried by military commission if jurisdiction exists. S. 1253, as reported out of the Senate Armed Services Committee, would authorize the detention of certain categories of persons and require the military detention of a subset of them; regulate status determinations for persons held pursuant to the AUMF, regardless of location; regulate periodic review proceedings concerning the continued detention of Guantanamo detainees; and make permanent the current funding restrictions that relate to Guantanamo detainee transfers to foreign countries. The Senate bill, however, would permit the transfer of detainees into the United States for trial or perhaps for other purposes.
