After the 1973 election, the composition was changed and the appointments by the Chogyal were eliminated, while at the same time the number of seats in the council was increased.

The Executive Council was presided over by the Dewan of Sikkim,[2] and each member within it was given individual government responsibilities.

After the Independence of neighbouring India in August 1947, various political bodies in Sikkim began to demand greater say in the kingdom's administration.

Under a parity formula agreed upon by the political groups, six of the electable seats were to be for the Sikkim Nepalis and the other six for the Bhutia-Lepcha (BL) people.

[6] The unrest led to the signing of a tripartite agreement, on 8 May, between the Choygal, Sikkimese political parties, and the government of India.

The Rajya Sabha voted for an amendment on 8 September, giving it a status equal to that of other states, and absorbing it in the Indian Union.

[17][18] On 8 September, the Chogyal cited "widespread Sikkimese misgivings over the bill", and called for a free and fair referendum.

[24][25][26] On 15 May, the Indian President Fakhruddin Ali Ahmed ratified the constitutional amendment (36th) that made Sikkim the 22nd state of India, and abolished the position of the Chogyal.

[27] The State Council was considered to be dissolved, and its members were deemed to be the new Legislative Assembly of Sikkim.
