Power of the court to determine constitutionality of a government action.

Explanation: Judicial review is a process that takes place in a Democratic Government, where the courts are empowered to be able to evaluate and review the activities of Government and other parties with the aim of ensuring that justice prevails. Judicial review proves that and every other person or organisation is restricted in what it may do as it regards the law and every person has rights which the government or any other party cannot take away from them.

The principle also suggests that fact that power of the court is to determine the constitutionality of the action of the government.
