UPSC IAS – 2015
The correct option is D.
The Supreme Court of India is considered the guardian and interpreter of the Constitution. It has the power of judicial review, which allows it to examine the constitutionality of laws passed by the Parliament and state legislatures and executive actions. If any law or action is found to be inconsistent with or violates the Constitution, the Supreme Court can declare it ultra vires (beyond the powers) and void. This power makes the Supreme Court the final arbiter and custodian of the Constitution.
While the President takes an oath to preserve, protect, and defend the Constitution, and Parliament is the legislative body that derives its powers from the Constitution, the ultimate authority to interpret the Constitution and ensure that all branches of government act within its framework rests with the judiciary, with the Supreme Court being the highest court.
