Non-Detention Act


The Non-Detention Act of 1971 was passed to repeal portions of McCarran Internal Security Act of 1950, specifically Title II, the "Emergency Detention Act". The United States statute repealed the Emergency Detention Act of 1950 provisioning the United States Attorney General powers for detention of any American or non-American citizen deemed as a threat to the national security of the United States. The 64 Stat. 1019 statute was codified within Title 50 War and National Defense as §§ 811-826.
The H.R. 234 legislation was passed by the 92nd United States Congressional session and enacted into law by the 37th President of the United States Richard Nixon on September 25, 1971.

Content of the Law

The Act of Congress allowed for detention of suspected subversives without the normal Constitutional checks required for imprisonment. The Non-Detention Act requires specific Congressional authorization for such detention. Passed as Public Law 92-128, 85 Stat. 347, it was codified at 18 U.S.C. § 4001.
§ 4001. Limitation on detention
In recent years, the statute has been used to challenge military detainment of U.S. citizens accused of terrorist activity. A Congressional Research Service report on the history of the Non-Detention Act concluded,
Legislative debate, committee reports, and the political context of 1971 indicate that when Congress enacted Section 4001 it intended the statutory language to restrict all detentions by the executive branch, not merely those by the Attorney General. Lawmakers, both supporters and opponents of Section 4001, recognized that it would restrict the President and military authorities.

Judicial Proceeding of Law

The Supreme Court of the United States originally took the case of Rumsfeld v. Padilla to decide the question of whether Congress's Authorization for Use of Military Force authorized the President to detain a U.S. citizen, but did not give an answer, instead ruling that the case had been improperly filed.
