Perfidy

In the context of war, perfidy is a form of deception in which one side promises to act in good faith (such as by raising a flag of truce) with the intention of breaking that promise once the unsuspecting enemy is exposed (such as by coming out of cover to take the "surrendering" prisoners into custody). Perfidy constitutes a breach of the laws of war and so is a war crime, as it degrades the protections and mutual restraints developed in the interest of all parties, combatants and civilians. Perfidy is specifically prohibited under the 1977 Protocol I Additional to the Geneva Conventions of 12 August 1949, which states: Article 37. – Prohibition of perfidy

1. It is prohibited to kill, injure or capture an adversary by resort to perfidy. Acts inviting the confidence of an adversary to lead him to believe that he is entitled to, or is obliged to accord, protection under the rules of international law applicable in armed conflict, with intent to betray that confidence, shall constitute perfidy. The following acts are examples of perfidy: (a) The feigning of an intent to negotiate under a flag of truce or of a surrender; (b) The feigning of an incapacitation by wounds or sickness; (c) The feigning of civilian, non-combatant status; and (d) The feigning of protected status by the use of signs, emblems or uniforms of the United Nations or of neutral or other States not Parties to the conflict.
2. Ruses of war are not prohibited. Such ruses are acts that are intended to mislead an adversary or to induce him to act recklessly but which infringe no rule of international law applicable in armed conflict and which are not perfidious because they do not invite the confidence of an adversary with respect to protection under that law. The following are examples of such ruses: the use of camouflage, decoys, mock operations and misinformation. Article 38. – Recognized emblems
3. It is prohibited to make improper use of the distinctive emblem of the red cross, red crescent or red lion and sun or of other emblems, signs or signals provided for by the Conventions or by this Protocol.
