Origin Rooted in English common law procedure and Magna Carta (1215); formally codified in the Habeas Corpus Act 1679.
Habeas corpus, Latin for that you have the body, is a legal action or writ requiring that a person under arrest be brought before a court so it can determine whether the detention is lawful. It is a core safeguard against arbitrary imprisonment, rooted in English common law procedure and Magna Carta (1215), and formally codified in the Habeas Corpus Act 1679. It is generally treated as suspendable only under narrow, extraordinary constitutional conditions; the United States Constitution, for example, permits suspension only in Cases of Rebellion or Invasion.
Facts
Disputed
Core PrincipleThe Suspension Clause of the United States Constitution (Article I, Section 9, Clause 2) permits Congress to suspend habeas corpus only in cases of rebellion or invasion when the public safety requires it, and only Congress, not the Executive, holds that power; how far the Clause reaches was contested in litigation over Guantanamo Bay detainees following the Detainee Treatment Act of 2005 and the Military Commissions Act of 2006, until the Supreme Court held in Boumediene v Bush (2008) that the Suspension Clause affirmatively guaranteed habeas review even for alien enemy combatants held outside the United States. 3 How far the constitutional right to habeas review extends beyond sovereign United States territory, and to whom, remains a genuinely contested question in wartime and national-security litigation.
