Boumediene v. Bush, 553 U.S. ___ (2008), was a writ of habeas corpus submission made in a civilian court of the United States on behalf of Lakhdar Boumediene, a naturalized citizen of Bosnia and Herzegovina, held in military detention by the United States at the Guantanamo Bay detention camps. The case was consolidated with habeas petition Al Odah v. United States. The case challenged the legality of Boumediene’s detention at the Guantanamo Bay military base as well as the constitutionality of the Military Commissions Act (MCA) of 2006. Oral arguments on the combined case were heard by the Supreme Court on December 5, 2007. On June 12, 2008, Justice Kennedy wrote the opinion for the 5-4 majority holding that the prisoners had a right to the habeas corpus under the United States Constitution and that the MCA was an unconstitutional suspension of that right.
