Today a divided three-judge panel of the U.S. Court of Appeals for the D.C. Circuit held that federal courts lack jurisdiction over the habeas corpus petitions filed by Guantanamo detainees. Judge Randolph wrote the majority decision for himself and Judge Sentelle. Judge Rogers dissented. I have not had time to read the decision yet, but it is available here.

UPDATE: For some initial commentary, see these two SCOTUSBlog posts by Lyle Denniston here and here, and Marty Lederman's initial thoughts on Balkinization.
