The Delhi Legislative Assembly was first constituted on 7 March 1952 under the Government of Part C States Act, 1951; it was inaugurated by Home Minister K. N. Katju.

The Assembly had 48 members, and a Council of Ministers in an advisory role to the Chief Commissioner of Delhi, though it also had powers to make laws.

This meant that Delhi was no longer a Part-C State and was made a Union Territory under the direct administration of the President of India.

[1][3] This Council was finally replaced by the Delhi Legislative Assembly through the Constitution (Sixty-ninth Amendment) Act, 1991, followed by the Government of National Capital Territory of Delhi Act, 1991 the Sixty-ninth Amendment to the Constitution of India, which declared the Union Territory of Delhi to be formally known as National Capital Territory of Delhi and also supplements the constitutional provisions relating to the Legislative Assembly and the Council of Ministers and related matters.

The building was originally built in 1912, designed by E. Montague Thomas to hold the Imperial Legislative Council and subsequently the Central Legislative Assembly (after 1919), until the newly constructed Parliament House of India in New Delhi (Sansad Bhawan) was inaugurated on 18 January 1927.
