The Constitution declares that the “Privilege of the Writ of Habeas Corpus” can be suspended by the federal government only “in Cases of Rebellion or Invasion [when] the public Safety may require it.” Because some regard this Habeas Clause as the Constitution’s only “emergency” provision, the Clause looms large in treatments of the Constitution’s…

In her book, Habeas Corpus in Wartime: From the Tower of London to Guantanamo Bay, Professor Amanda Tyler has written a definitive constitutional history of the habeas privilege in the United States.

Among the causes of turbulence in constitutional tort doctrine and the surrounding literature is a failure—not only among the Justices, but also among…

This Article compares and contrasts the legal and political treatment of the detention of citizens during World War II in Great Britain and the United States.

Roosevelt and Prime Minister Winston Churchill took with respect to the detention of…

Four months into the convulsive aftermath of the September 11 attacks, the first George W. Bush Administration began to detain “enemy combatant” designees at the American military base in Guantanamo Bay, Cuba (GTMO).
