A more thorough explanation:

NULLIUS JURIS

nullius juris is a Latin term that means "of no legal force." It refers to something that has no legal validity or authority.

• A contract that was signed under duress is nullius juris and cannot be enforced in court.
• A law that violates the constitution is nullius juris and cannot be enforced.

These examples illustrate how something can be considered nullius juris if it goes against legal principles or is not legally binding. In both cases, the contracts and laws are not recognized as valid because they do not meet the legal requirements for enforceability.
