Enemy Combatant - Change of Meaning in The United States

Change of Meaning in The United States

In the 1942 Supreme Court of the United States ruling Ex Parte Quirin, the Court uses the terms with their historical meanings to distinguish between unlawful combatants and lawful combatants:

Unlawful combatants are likewise subject to capture and detention, but in addition they are subject to trial and punishment by military tribunals for acts which render their belligerency unlawful. The spy who secretly and without uniform passes the military lines of a belligerent in time of war, seeking to gather military information and communicate it to the enemy, or an enemy combatant who without uniform comes secretly through the lines for the purpose of waging war by destruction of life or property, are familiar examples of belligerents who are generally deemed not to be entitled to the status of prisoners of war, but to be offenders against the law of war subject to trial and punishment by military tribunals.(Emphasis added)

In the wake of the September 11, 2001 attacks the United States Congress passed a resolution known as the Authorization for Use of Military Force Against Terrorists (AUMF) on September 14, 2001, wherein the Congress invoked the War Powers Resolution. Using this authorization granted to him by Congress, on November 13, 2001, President George W. Bush issued a Presidential Military Order: "Detention, Treatment, and Trial of Certain Non-Citizens in the War Against Terrorism". The administration chose to call those who it detained under the Presidential Military Orders "enemy combatants". Since then, the administration has formalized its usage of the term by using it specifically for detained alleged members and supporters of al-Qaida or the Taliban. For example

Under the provisions of the Secretary of the Navy Memorandum Implementation of Combatant Status Review Tribunal Procedures for Enemy Combatant Detained at Guantanamo Bay Naval Base Cuba ... An enemy combatant has been defined as "an individual who was part of or supporting the Taliban or al Qaida forces, or associated forces that are engaged in hostilities against the United States or its coalition partners. This includes any person who committed a belligerent act or has directly supported hostilities in aid of enemy armed forces."

This lead has been followed by other parts of the Government and some section of the American news media. The result of this new usage means that the term "enemy combatant" has to be read in the context of the article in which it appears as to whether it means a member of the armed forces of an enemy state, or if it means an alleged member of al Qaida held prisoner by the United States.
