Whether 28 U.S.C. § 2241 permits federal courts to hear habeas challenges by foreign nationals detained at Guantanamo Bay.
Holding
Yes. Section 2241 gives the District Court jurisdiction to hear the detainees' challenges to the legality of their detention at Guantanamo Bay.
Reasoning
The federal habeas statute authorizes district courts to entertain applications by any person held in custody in violation of the Constitution, laws, or treaties of the United States. Habeas corpus has historically been a central means of testing the legality of Executive detention, especially detention imposed without a judicial trial.
The phrase “within their respective jurisdictions” does not require the prisoner to be physically located within the territorial boundaries of the district court. Under Braden v. 30th Judicial Circuit Court of Kentucky, habeas jurisdiction turns on whether the court can reach the custodian by service of process. No party disputed that the District Court had jurisdiction over the detainees' custodians.
Guantanamo is not foreign territory in the sense relevant to the Government's extraterritoriality argument. Although Cuba retains ultimate sovereignty under the lease agreements, the United States has exercised complete, exclusive, and potentially permanent jurisdiction and control over the base. The habeas statute does not distinguish between citizens and aliens in federal custody, so its geographic reach cannot reasonably depend on the detainee's citizenship.
The Court's conclusion also accords with the common-law history of habeas corpus. English courts issued the writ not only within the sovereign's formal territory, but also in places subject in fact to the Crown's dominion and control. The practical extent of governmental control, rather than a formal label of sovereignty, was the relevant consideration.
