Usage
Usually functions as an uncountable noun in legal discourse; often paired with its counterpart 'actus reus'.
Teaching tip
contrast with 'actus reus' (the physical act of the crime) to help students understand the two components required for criminal liability in common law systems.
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.
