Which Constitutional Amendment Act integrated Sikkim as the full-fledged twenty-second State of the Indian Union?

💡 Solution & Explanation

The Thirty Sixth Constitutional Amendment Act of 1975 was enacted to make Sikkim a full-fledged State of the Indian Union, abolishing its prior status as an associate state. The Thirty Fifth Amendment had previously introduced the associate state status under Article 2A, which was subsequently repealed by the same Thirty Sixth Amendment. Article 371F was also introduced to make special provisions for the administration of Sikkim. The historic transition concluded the integration process following a public referendum held in the region.
