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 A month later, the 36th Amendment repealed the 35th Amendment, and made Sikkim a full state, adding its name to the First Schedule of the Constitution.[42]
