The November 13, 2001, Presidential Military Order gave the President of the United States the power to detain a non-citizen suspected of connection to terrorists or terrorism as an unlawful combatant. As such, it was asserted that a person could be held indefinitely without charges being filed against him or her, without a court hearing, and without entitlement to a legal consultant. Many legal and constitutional scholars contended that these provisions were in direct opposition to habeas corpus and the United States Bill of Rights.

On June 7, 2007, the Habeas Corpus Restoration Act of 2007 was approved by the Senate Judiciary Committee with an 11-8 vote split along party lines, with all but one Republican voting against it.
