sentences:  In a plurality opinion issued on July 15, 2008, the court held that the president did have authority to hold Al-Marri in military custody, but that Al-Marri was entitled to a greater, but undefined, degree of due process in his habeas corpus petition than had been accorded by the court below.The Supreme Court granted "certiorari".Shortly following his becoming president, President Barack Obama ordered Al-Marri transferred to civilian authorities, and the Supreme Court dismissed the case as moot on March 6, 2009.
