illegal act

Offense against society

An illegal act is any behavior that violates the law—a crime, offense, or prohibited conduct.

The phrase is somewhat formal and appears often in legal contexts: The contract is void if it requires an illegal act.

It covers everything from minor infractions to serious felonies, emphasizing the unlawfulness rather than the specific nature of the conduct.
