sikkim was made an integral part of india under which amendment
Sikkim In 1975, the Prime Minister of Sikkim appealed to the Indian Parliament for Sikkim to become a state of India. In April of that year, the Indian Army took over the city of Gangtok and disarmed the Chogyal's palace guards. Thereafter, a referendum was held in which 97.5 per cent of voters supported abolishing the monarchy, effectively approving union with India. India is said to have stationed 20,000â€“40,000 troops in a country of only 200,000 during the referendum.[40] On 16 May 1975, Sikkim became the 22nd state of the Indian Union, and the monarchy was abolished.[41] To enable the incorporation of the new state, the Indian Parliament amended the Indian Constitution. First, the 35th Amendment laid down a set of conditions that made Sikkim an "Associate State", a special designation not used by any other state. A month later, the 36th Amendment repealed the 35th Amendment, and made Sikkim a full state, adding its name to the First Schedule of the Constitution.[42]
Forty-second Amendment of the Constitution of India The Forty-second Amendment of the Constitution of India, officially known as The Constitution (Forty-second amendment) Act, 1976, was enacted during the Emergency (25 June 1975 â€“ 21 March 1977) by the Indian National Congress government headed by Indira Gandhi.[1] Most provisions of the amendment came into effect on 3 January 1977, others were enforced from 1 February and Section 27 came into force on 1 April 1977. The 42nd Amendment is regarded as the most controversial constitutional amendment in Indian history. It attempted to reduce the power of the Supreme Court and High Courts to pronounce upon the constitutional validity of laws. It laid down the Fundamental Duties of Indian citizens to the nation. This amendment brought about the most widespread changes to the Constitution in its history, and is sometimes called a "mini-Constitution" or the "Constitution of Indira".[2]
