What is the legal definition of an unlawful combatant?

An unlawful combatant, also referred to as an unprivileged combatant or belligerent, is generally defined as a civilian who directly engages in armed conflict in violation of the laws of war. Because of this status, they are typically deemed in national legal systems to be unprotected by standard prisoner-of-war privileges, though they may retain basic rights under other international frameworks. The terminology and application of the concept have been subjects of significant controversy and varied legal interpretations, particularly by governments involved in recent conflicts.

What we know

• Unlawful combatants are civilians who directly engage in armed conflict and are legally deemed in some national systems to lack Geneva Convention prisoner-of-war protections. [2]
• The phrase 'unlawful combatant' does not actually appear within the text of the Third Geneva Convention, though the concept is included within it. [2]
• In the United States, the Military Commissions Act of 2006 codified a legal definition for the term and gave the president broad discretion over unlawful enemy combatant designations. [2]
• Detainees whose combatant status is in doubt must have their status determined by a competent tribunal and must be treated as prisoners of war until such a determination is made, according to Article 5 of the Third Geneva Convention. [2]
• The concept originated during the fin de siècle of the 19th century when great powers considered francs-tireurs to be unlawful combatants. [1, 2]

Still open

• The International Committee of the Red Cross has criticized the concept because terms like unlawful or unprivileged combatant are not defined in any international agreements.
