On 2 April, the Supreme Court refused to hear the joint cases of two groups of Guantánamo Bay detainees seeking a review of their detention. Following that decision, the Department of Justice requested the District Court in Washington to dismiss all pending cases of Guantánamo Bay detainees challenging their indefinite detention. The detainees’ lawyers unsuccessfully requested the suspension of the decision by the Supreme Court. On 30 April, the Supreme Court refused to hear another case brought by Guantánamo Bay detainees on habeas corpus rights.
