Glossary

Actus reus

guilty act

common-law

The physical element of an offence: the prohibited conduct, circumstances or result.

In more detail

Liability normally requires the actus reus and mens rea to coincide. Omissions count only where a legal duty to act exists, which is why duty-creating relationships and statutory duties are central to omission liability.
