What does the term actus reus mean in legal contexts?

The term actus reus is a fundamental concept in criminal law that refers specifically to the physical act or conduct that constitutes a criminal offense. It encompasses the actions taken by an individual that lead to the commission of a crime. This concept emphasizes the importance of a relevant, tangible action or a failure to act, as opposed to just intentions or thoughts about committing a crime.

In legal contexts, establishing actus reus is crucial for determining liability; an individual must have performed an unlawful act to be held criminally responsible. Therefore, the correct answer accurately captures the essence of actus reus as it directly relates to the tangible conduct that forms the basis of a criminal charge.
