What is done contrary to law is deemed not to have been done.

Explanation

An act performed in violation of law is treated as a nullity — it creates no rights, imposes no obligations, and is regarded as though it never occurred.

Where this applies

• A government act done without lawful authority is treated as if it never happened.
• A contract executed in violation of the law is deemed void from the start.
