Answer:
The answer is judicial review.
Explanation:
The judicial review consists of a process in which the judiciary reviews executive or legislative actions. A court which has the authority to make judicial review could invalidate laws or governmental actions that don't have a relationship with a higher authority.
If an executive decision is unlawful, it could be invalidated or a statute could also be invalidated because it is violating aspects related to the Constitution. Judicial review is considered an element of the checks and balances related to the separation of powers.
