What Is The 51st Amendment Of Indian Constitution?

On 29th April 1985, the 51st Amendment of Indian Constitution came into effect. This constitutional amendment modifies articles 330 and 332. When this amendment was approved, Indira Gandhi was the prime minister.

This amendment was passed to ensure that scheduled tribes in Mizoram, Nagaland, Arunachal Pradesh, and Meghalaya, have access to seats in the Lok Sabha. Also, this amendment grants the reservation of seats for scheduled tribes in the legislative assemblies of Nagaland and Meghalaya. This was done by suitably changing articles 330 and 332.

With consideration of the provision in article 332(3) of the constitution, the number of seats designated for scheduled castes and scheduled tribes in the legislative assembly of any state must be established.

Objects And Reasons

On March 31, 1980, the Meghalaya Legislative Assembly passed a resolution encouraging the Government of India to establish reservations for members of the Scheduled Tribes in both the State Legislative Assembly and the House of the People, following the example set by other States throughout the nation.

As a result, the State Government suggested amendments to Articles 330 and 332 of the Constitution. The modification has also received support from the governments of Mizoram, Arunachal Pradesh, and Nagaland with regard to their respective regions. Article 330 of the Constitution is being suggested for change. This was done to provide for the reservation of seats in the Lok Sabha for the Scheduled Tribes of Meghalaya, Nagaland, Arunachal Pradesh, and Mizoram. The Legislative Assemblies of Nagaland and Meghalaya would also have a similar reservation under article 332. To accommodate the needs of the nearby tribal population, changes have been proposed.

This bill aims to do the goal mentioned above.
