Meaning of judicial Review :
This means that the Supreme Court has the provision of protecting the constitution and its supremacy. If the constitution is encroached by the federal state Legislature, laws are created outside certain boundaries or laws are created against fundamental rights, then every law made by the federal parliament can be declared illegal by the Supreme Court. This is called the power of judicial review. Regarding the state,this power can be used by the concerned High Court.
Importance :
1. The power that has been partitioned between the federal and the state government by the constitution is protected only on the basis of a judiciary review.
2. The task of curbing the power of the government and protecting civil rights and freedoms can also be done on the basis of a judiciary review.
3. Judiciary review is a major means of regulating power of governance.
4. The system of judicial review serves as the balance-cycle of the constitution.
5. On the basis of judicial review, the Supreme Court and High Courts can act as the official interpreters and guardians of the constitution.
6. The power of testing the legality of laws is related to judicial review. Article 131 and 132 give the right to the Supreme Court to review the laws created by the federal and state government.
It is evident from the above description that the two powerful figures of judicial review are the federal system and the fundamental rights.
