The correct answer is Twenty-fourth Amendment. Key Points The Twenty-fourth Amendment of the Constitution of India, officially known as The Constitution (Twenty-fourth Amendment) Act, 1971, enables Parliament to dilute Fundamental Rights through Amendments of the Constitution. It also amended Article 368 to provide expressly that Parliament has the power to amend any provision of the Constitution. The 24th Amendment modified Articles 13 and 368 to authorize Parliament to freely amend the Fundamental Rights. Article 13 stated that any law which was inconsistent with the Fundamental Rights was invalid.​ Important Points In the Golak Nath case, the Supreme Court ruled that the word ‘law’ also included constitutional amendments; as a result, any constitutional amendment which violated the Fundamental Rights was invalid. So Parliament would not be able to use constitutional amendments to curtail the Fundamental Rights. The 24th Amendment inserted clause (4) to Article 13, which stated that Article 13 would not apply to any constitutional amendments, effectively overturning Golak Nath. Article 368 lays down the procedure to amend the Constitution. Under the original Constitution, any constitutional amendment would only come into force if two conditions were met: first, if two-thirds of the members of each House of Parliament voted in its favour; second if it received the assent of the President, who had the option of withholding assent. The Amendment modified the second condition, to provide that the President was bound to give his assent to the Bill - they had no choice. The 24th Amendment was partially overturned in 1973 when the Supreme Court held in Kesavananda Bharati v. State of Kerala that Parliament could not amend the 'basic structure' of the Constitution. In this case, 11 judges held that certain basic or essential features of the Constitution were beyond the scope of Parliament’s amending powers. Both Articles 13 and 368 continue to exist in their amended form. However, through various causes, the Courts have strived to not allow these Articles to undermine the basic structure of the Constitution.
