The Indian Independence Act, 1947 is the statute of the British Parliament that ended colonial rule in India and created two independent dominions — India and Pakistan — with effect from 15 August 1947. It withdrew British sovereignty over the subcontinent, dissolved the office of Viceroy, and handed full constitution-making power to the Constituent Assemblies of the two new dominions.

Background: From Atlee's Declaration to the Mountbatten Plan

On 20 February 1947, British Prime Minister Clement Atlee announced that British rule in India would end by June 1948 and that power would be transferred to Indian hands. This declaration triggered intensified agitation by the Muslim League for the partition of the country. On 3 June 1947, the British government clarified that any constitution framed by the Constituent Assembly (which had been formed in 1946) would not bind the parts of the country unwilling to accept it. On the same day, Viceroy Lord Mountbatten put forward a partition plan — the Mountbatten Plan — which was accepted by both the Indian National Congress and the Muslim League.

The Indian Independence Bill was introduced in the British Parliament on 4 July 1947, received Royal Assent on 18 July 1947, and came into force on 15 August 1947, giving immediate legal effect to the Mountbatten Plan.

Key Provisions of the Act

Provision What it did
End of British rule Declared India an independent state from 15 August 1947
Partition Created two independent dominions, India and Pakistan, each free to secede from the British Commonwealth
Abolition of the Viceroy Replaced the office with a Governor-General for each dominion, appointed by the British King on the advice of the dominion's own cabinet
End of British responsibility His Majesty's Government in Britain ceased to have any responsibility for the governance of India or Pakistan
Constitution-making power Empowered the Constituent Assemblies of both dominions to frame and adopt any constitution they pleased, and to repeal any Act of the British Parliament — including the Independence Act itself
Interim law-making power Empowered the Constituent Assemblies to legislate for their respective territories until new constitutions were drafted and enforced

No Act of the British Parliament passed after 15 August 1947 could be extended to India unless the Dominion Legislature itself adopted it — a decisive break from colonial legal subordination.

Impact on the Constituent Assembly

The Act transformed the character of India's Constituent Assembly in two important ways. First, it made the Assembly a fully sovereign body, free to frame any constitution it wished and empowered to abrogate or alter any law the British Parliament had earlier made for India. Second, it made the Assembly a legislative body as well, so that it now performed two distinct functions on separate days: framing the Constitution of free India, and enacting ordinary laws as the country's provisional Parliament (Dominion Legislature). When the Assembly met to draft the Constitution, it was chaired by Dr. Rajendra Prasad; when it met as the legislative body, it was chaired by G.V. Mavalankar.

Princely States and the Right to Accede

The Act freed princely states from paramountcy and left them free to join India, join Pakistan, or, in principle, remain outside both dominions. Representatives of six princely states had already joined the Constituent Assembly by 28 April 1947. After the Mountbatten Plan was accepted on 3 June 1947, representatives of most of the remaining princely states, along with Muslim League members from the Indian Dominion, also took their seats in the Assembly.

The Hyderabad case illustrates how contentious this freedom could be. The Nizam of Hyderabad initially sought independence rather than accession, and a Standstill Agreement was signed to manage the interim relationship with India. When negotiations broke down amid the activities of the Nizam's paramilitary Razakars, the Indian Army moved into Hyderabad in 1948; the Nizam surrendered, and Hyderabad acceded to the Indian Union.

Partition and the Boundary Commission

The territorial division between the two new dominions was settled by a Boundary Commission headed by Sir Cyril Radcliffe. Under this exercise, Pakistan came to include West Punjab, Sind, Baluchistan, East Bengal, the North-Western Frontier Province, and the Sylhet district of Assam — the last two included after referendums in those areas favoured joining Pakistan.

Independence Day and Its Aftermath

India's independence was formally marked at midnight on 14–15 August 1947, with Jawaharlal Nehru's "tryst with destiny" speech. The newly independent nation immediately confronted three major challenges: building unity amid enormous diversity, establishing a functioning democracy, and pursuing development with equality and justice. Mahatma Gandhi did not join the official celebrations; he remained in Kolkata, then a city scarred by communal riots, working to restore peace between Hindus and Muslims before later moving to Delhi to address violence there as well.

Repeal and Legacy

The Indian Independence Act, 1947 remained in force through the transitional period as the legal basis for India's Dominion status. It was repealed, along with the Government of India Act, 1935 and its amending and supplementing enactments, when the Constitution of India came fully into force on 26 January 1950. From that date, India ceased to be a Dominion governed under a British statute and became a sovereign republic governed by a Constitution of its own making — the very outcome the Independence Act had made legally possible.
