Summary execution
In civil and military jurisprudence, summary execution (also called field execution) is the putting to death of a person accused of a crime without the benefit of a free and fair trial. The term results from the legal concept of summary justice to punish a summary offense, as in the case of a drumhead court-martial, but the term usually denotes the summary execution of a sentence of death. Under international law, it is defined as a combatant's refusal to accept an opponent's lawful surrender and the combatant's provision of no quarter, by killing the surrendering opponents.
