As Prof. Steve Vladeck summarizes, Sec. 1037 of the FY2011 NDAA:
[T]itled “Inspector General Investigation of the Conduct and Practices of Lawyers Representing Individuals Detained at Naval Station, Guantanamo Bay, Cuba,” instructs the Department of Defense IG to “conduct an investigation of the conduct and practices of lawyers” who represent clients at Guantánamo and report back to the House and Senate Armed Services Committees within 90 days.
Page 403 of the NDAA is where Sec. 1037 begins, see here. Covered lawyers under Sec. 1037 include uniformed judge advocates and civilian counsel that represented Gitmo detainees. The bill seems to be a resposne to the Fitzgerald investigation and facts leading up to it, see Newsweek here. But, I agree with Prof. Vladeck that it is incredibly broad and could be read to sweep in almost every lawyer that ever practiced before the Commissions.
