  1. 01 C2 Proficiency FormalTechnicalAcademic Law

    the mental state of knowing you are doing something wrong when you commit a crime.

    the state of mind that the prosecution must prove a defendant had to secure a conviction for a particular crime. It is the subjective element of an offence, distinct from the physical act.

    Simple

    The lawyer argued that his client lacked the mens rea to commit fraud because he made an honest mistake.

    In context

    To secure a conviction for first-degree murder, the prosecution must establish both the actus reus and the specific mens rea of premeditation.

    Usage

    Usually functions as an uncountable noun in legal discourse; often paired with its counterpart 'actus reus'.

    Teacher's tip

    This is a highly technical Latin term used in legal contexts; students should understand it as the 'mental' part of a crime versus the 'physical' part.
