Common questions
Why does the law require a voluntary act for actus reus to be established?+
An act performed involuntarily, such as during a seizure or under physical compulsion by another person, is not treated as a true exercise of the defendant's will, so it cannot ground criminal liability regardless of its physical consequences.
Is actus reus alone enough to establish a criminal offence?+
No, most offences also require mens rea, the accompanying guilty state of mind, so proving the physical act occurred is only half of what the prosecution must establish for such offences.
