For a more detailed discussion of individual topics, see automatism (case law) In the Criminal Law, automatism is a defense to liability. Except in the case of strict liability offences, a crime must contain two elements: the actus reus or "guilty act", and the mens rea or "guilty mind". This defense seeks to prove that the criminal defendant made only physical movements and did not "act" as required to prove the actus reus. The term describes movements that are characteristic of an automaton, i.e. a machine that moves.
