After the U.S. Supreme Court held that U.S. courts have
jurisdiction to hear legal challenges on behalf of more than 500 persons detained at the U.S. Naval
Station in Guantanamo Bay, Cuba in connection with the war against terrorism, the Pentagon
established administrative hearings, called "Combatant Status Review Tribunals" (CSRTs), to allow
the detainees to contest their status as enemy combatants. This report provides an overview of the
CSRT procedures and summarizes court cases related to the detentions and the use of military
commissions. The relevant Supreme Court rulings are discussed in CRS Report RS21884, The
Supreme Court and Detainees in the War on Terrorism: Summary and Analysis. This report will
be updated as events warrant.
