from "alien detained ... at Guantanamo Bay": The Supreme Court ruled in Boumediene v. Bush that the MCA amounts to an unconstitutional encroachment on habeas corpus rights, and established jurisdiction for federal courts to hear petitions for habeas corpus from Guantanamo detainees tried under the Act. Under the MCA, the law restricted habeas appeals for only those aliens detained as enemy combatants, or awaiting such determination. Left unchanged was the provision that, after such determination is made, it is subject to appeal in federal courts, including a review of whether the evidence warrants the determination. If the status was upheld, then their imprisonment was deemed lawful; if not, then the government could change the prisoner's status to something else, at which point the habeas restrictions no longer applied.

The U.S. Supreme Court then reversed its decision to deny review and took up the case in June 2007. In June 2008, the court ruled 5-4 that the act did suspend habeas and found it unconstitutional. On June 11, 2007, a federal appeals court ruled that Ali Saleh Kahlah al-Marri, a legal resident of the United States, could not be detained indefinitely without charge. In a two-to-one ruling by the U.S. Court of Appeals for the Fourth Circuit, the Court held the President of the United States lacks legal authority to detain al-Marri without charge; all three judges ruled that al-Marri
