In the fall of 2001, the Bush administration was looking for a place to imprison and interrogate alleged al Qaeda members away from the prying eyes of other countries and insulated from the supervision of United States courts. The Defense Department believed that the Naval Base at Guantánamo Bay, Cuba might work, so it asked the Justice Department’s Office of Legal Counsel (OLC) whether federal courts would entertain habeas corpus petitions filed by prisoners at Guantánamo, or whether they would dismiss such petitions as beyond their jurisdiction. On December 28, 2001, OLC responded with a thorough and balanced analysis of how the federal courts were likely to resolve the jurisdictional question. The memorandum prepared by OLC explained the arguments against such jurisdiction, but it also explored possible strengths in the opposing position. The memorandum predicted that federal courts would not exercise jurisdiction but explained the risk of a contrary ruling. Acting in reliance on this memorandum, the government started imprisoning and interrogating alleged al Qaeda members at Guantánamo the following month, cognizant of the risk that a federal court might find habeas jurisdiction.
