June 3 Plan of 1947

The June 3 Plan of 1947, also called the Mountbatten Plan or the Plan Partition, was the formal British proposal announced simultaneously in London and New Delhi on 3 June 1947 that settled the method by which power would be transferred from the British Crown to successor governments in the Indian subcontinent. Its legal authority derived from the British Government's policy statement of 20 February 1947, in which Prime Minister Clement Attlee declared that the British would quit India by June 1948 and announced Lord Louis Mountbatten's appointment as the last Viceroy. The June 3 Plan superseded the Cabinet Mission Plan of 1946, which had envisaged a loose three-tier Indian Union with grouped provinces and had collapsed amid irreconcilable interpretations by the Indian National Congress and the All-India Muslim League. The June 3 Plan accepted, for the first time in an official British proposal, the principle that India might be partitioned into two sovereign dominions.

Procedurally, the plan established a sequence of consent mechanisms rather than imposing partition by fiat. The legislative assemblies of Bengal and Punjab were to meet in two parts—one representing Muslim-majority districts and one representing the remainder—and a simple majority of either part voting for partition would carry the division of that province. Sind's Legislative Assembly was to take its own decision by vote. In the North-West Frontier Province, where a Congress ministry held office, and in the Sylhet district of Assam, referenda were to determine accession. British Baluchistan's status was to be decided through the Shahi Jirga and the Quetta municipality. Should partition be chosen, a Boundary Commission would demarcate the frontiers of the divided provinces. Most consequentially, the plan advanced the date of the transfer of power from the previously stated June 1948 to 15 August 1947, compressing the timetable to roughly ten weeks.

The plan also addressed the princely states and the constitutional architecture of succession. Paramountcy—the suzerainty the Crown exercised over the roughly 565 princely states—would lapse on the transfer of power and would not be inherited by either successor dominion; states were left to accede to India or Pakistan or, in theory, remain independent. Two constituent assemblies would frame separate constitutions, and until they did so, the two dominions would be governed under a modified Government of India Act, 1935. The plan's provisions were translated into statute as the Indian Independence Act, 1947, which received royal assent on 18 July 1947, creating the Dominions of India and Pakistan effective 15 August 1947 and conferring on each the right to secede from the Commonwealth.

The named outcomes followed rapidly. The Muslim League Council accepted the plan on 9 June 1947 and the Congress Working Committee on 14–15 June 1947, with Mahatma Gandhi reluctantly acquiescing. The Punjab and Bengal assemblies voted for partition in late June 1947. The NWFP referendum of July 1947, boycotted by Khan Abdul Ghaffar Khan's Khudai Khidmatgars, returned a vote for Pakistan, as did the Sylhet referendum. Sir Cyril Radcliffe chaired the two Boundary Commissions; the Radcliffe Award was finalised on 12 August but withheld until 16–17 August 1947, after Independence. Sardar Vallabhbhai Patel and V. P. Menon led the parallel effort, through the States Department created in July 1947, to secure the accession of the princely states.

The June 3 Plan must be distinguished from the abandoned Plan Balkan, an earlier Mountbatten draft (prepared in May 1947 and known as the "Dickie Bird Plan") that would have devolved power to individual provinces and states, risking the fragmentation of India into numerous units. V. P. Menon and Jawaharlal Nehru's objections at Simla led to its rejection in favour of the dominion-status formula of the June 3 Plan. It is equally distinct from the Cripps Mission of 1942, which offered dominion status after the war but was rejected, and from the Cabinet Mission Plan, which had explicitly sought to avoid partition through provincial grouping. The June 3 Plan's innovation lay less in inventing partition than in marrying it to immediate dominion status and an accelerated date.

Controversy has centred on the compression of the timetable and its human cost. The decision to advance the transfer to 15 August 1947 left the administrative machinery, the armed forces, and the police only weeks to divide assets and prepare for population movements, contributing to communal violence that displaced an estimated ten to fifteen million people and killed hundreds of thousands across Punjab and Bengal. Critics, including later historians, have faulted Mountbatten for haste and for the decision to publish the Radcliffe Award only after Independence, which left frontier districts in uncertainty during the most violent weeks. Defenders argue that the deteriorating law-and-order situation and the breakdown of the interim government left no realistic alternative.

For the working practitioner—and especially the civil-services aspirant studying modern Indian history—the June 3 Plan is the pivot on which the constitutional decolonisation of South Asia turned. It is the document that converted an aspiration to quit India into a dated, statute-backed mechanism, and it illustrates how partition was effected through provincial consent procedures rather than a single imperial decree. Understanding the plan clarifies the legal lineage running from Attlee's February statement through the June 3 announcement to the Indian Independence Act, and it frames the unresolved questions—princely accession, the Radcliffe line, Kashmir—that shaped the subcontinent's subsequent diplomacy and remain live in India–Pakistan relations.
