Practice Relating to Rule 65. Perfidy
Section C. Simulation of being disabled by injuries or sickness
Switzerland’s Basic Military Manual (1987) provides that perfidy is forbidden and that: “It is notably prohibited … to feign incapacitation for combat by wounds or sickness”.
Switzerland’s ABC of International Humanitarian Law (2009) states:
International humanitarian law prohibits killing, injuring or capturing an adversary by resorting to perfidy. Acts of perfidy include any form of deception designed to win the confidence of an adversary and lead him to believe that he is entitled or obliged to accord protection under the rules of international humanitarian law, with the intention of betraying that confidence. An example of perfidy is to falsely lay claim to protected status through … feigning incapacitation on the grounds of injuries or sickness.
