Who/Which of the following is the custodian of the Constitution of India?

The Supreme Court of India acts as the final interpreter and guardian of the Constitution. Its role as the 'custodian' or 'guardian' of the Constitution implies several key functions:

Judicial Review: The Supreme Court has the power of judicial review, allowing it to examine the constitutionality of legislative enactments and executive orders of both the Centre and the states. If a law or order violates the Constitution, it can be declared null and void by the Supreme Court. Protector of Fundamental Rights: It safeguards the fundamental rights of citizens, acting as the guarantor of these rights as enshrined in the Constitution. Upholding Constitutional Supremacy: By ensuring that all laws and actions of the government adhere to the provisions of the Constitution, the Supreme Court maintains the supremacy of the Constitution. Arbitration of Disputes: It resolves disputes between the Centre and the states, or between states, concerning constitutional matters. While the President is the head of state and upholds the Constitution, and Parliament makes laws, it is the Supreme Court that ultimately interprets and protects the Constitution from any encroachment or violation.
