The Directive Principles of State Policy are not enforceable in a Court of law, but the principles laid down there are considered fundamental in the governance of the country making it the duty of the State to apply these principles in making law to establish a just society in the country.

The concept of Judicial Review' in Indian Constitution has been adopted from the Constitution of the United States. Judicial review is the power of the courts to examine the actions of the legislative, executive and administrative arms of the Government and to determine whether such actions are consistent with the Constitution. Actions judged inconsistent are declared unconstitutional and therefore null and void.

The doctrine of Judicial Review has been originated and developed in the USA. It was propounded for the first time in the famous case of Marbury v/s Madison (1803) by John Marshall, the then Chief Justice of the American Supreme Court. The Constitution of India confers the power of Judicial review on the Judiciary i.e. both the Supreme Court as well as High Courts. The Supreme Court has declared the power of Judicial Review as a basic structure of the Constitution.

The Constitution of India adopted the process of 'Judicial Review' from the U.S. Constitution which is not applicable in the British Parliamentary System while rest of the options are applicable to both the Parliamentary systems.
