3rd June Plan & Indian Independence Act 1947

🎯

Topic: 3rd June Plan & Indian Independence Act 1947 — Lecture 35. The final British partition plan (Mountbatten Plan) and the subsequent Act of Parliament that formally ended British rule and created India and Pakistan, including the Radcliffe Boundary Commission's border demarcation.

Note: No transcript was available; compiled independently for CSS Pakistan Affairs, building on the Cabinet Mission Plan and General Elections notes already in this collection.

CSS relevance: Extremely high — this is the capstone event of the entire pre-partition series, and the Radcliffe Line's flawed process is a frequently tested critique.

Overview

• Following the Cabinet Mission Plan's collapse and Direct Action Day's violence (see the dedicated notes), Lord Louis Mountbatten was appointed the last Viceroy of India in March 1947, tasked with finalising and accelerating the transfer of power.
• Mountbatten concluded that continued efforts to preserve a united India were untenable given the scale of communal violence and the parties' irreconcilable positions, and moved toward a partition-based settlement.

The 3rd June Plan (Mountbatten Plan)

• Announced on 3 June 1947, hence its common name.
• Key provisions:
  1. British India would be partitioned into two independent dominions: India and Pakistan.
  2. Punjab and Bengal, both containing substantial non-Muslim populations, would themselves be partitioned, with their legislative assemblies voting (split by district/community) on whether to join India or Pakistan, and whether the provinces themselves should be divided.
  3. A boundary commission would be established to demarcate the actual borders within Punjab and Bengal, based on contiguous majority areas of Muslims and non-Muslims, while also considering other factors.
  4. Sindh's legislative assembly would decide by simple vote which dominion to join (it opted for Pakistan).
  5. NWFP would hold a referendum to decide between India and Pakistan (it voted, by a large majority of votes cast, for Pakistan; Congress-aligned local leadership under the Khudai Khidmatgar movement largely boycotted the vote).
  6. Balochistan's decision was made through its Shahi Jirga (tribal assembly) and Quetta Municipality, which opted for Pakistan.
  7. Princely states were given the choice to accede to either dominion, or (in principle) remain independent, taking into account geographic contiguity and the wishes of their populations.
  8. The transfer of power was to occur on 15 August 1947 — a date significantly earlier than most had anticipated, reflecting Mountbatten's determination to accelerate the process given the deteriorating communal situation.
• Both the Indian National Congress and the Muslim League accepted the plan, marking the first time both parties agreed on the principle of partition as the resolution to the constitutional deadlock.

The Indian Independence Act, 1947

• Passed by the British Parliament in July 1947, giving legal/statutory effect to the 3rd June Plan.
• Key provisions:
  1. Created two independent dominions, India and Pakistan, effective 15 August 1947.
  2. Ended British paramountcy over the princely states, leaving them free to accede to either dominion.
  3. Provided for the division of assets, liabilities, and the armed forces between the two new dominions.
  4. Each dominion would have its own Governor-General and would initially operate under the existing Government of India Act 1935 (see the dedicated notes) as a provisional constitution, pending each country drafting its own permanent constitution.
  5. Ended the British Crown's sovereignty over British India entirely.

The Radcliffe Boundary Commission

• Chaired by Sir Cyril Radcliffe, a British barrister with no prior experience of India, appointed to head two separate boundary commissions (for Punjab and for Bengal), tasked with demarcating the actual border lines within just a few weeks.
• Given the extraordinarily compressed timeframe (roughly five weeks) and Radcliffe's unfamiliarity with local ground realities, the resulting boundary — the Radcliffe Line — has been widely and persistently criticised by historians as hastily drawn, poorly informed, and a direct contributor to the massive scale of violence and displacement that accompanied partition.
• The boundary award was not published until 17 August 1947 — after independence had already been declared on 15 August — leaving both new countries to begin their existence without knowing their exact borders for the first two days, contributing further to the chaos and uncertainty of the transition.
• The partition triggered one of the largest mass migrations in human history, with an estimated 10-15 million people crossing the new borders, and widespread communal violence resulting in an estimated several hundred thousand to over a million deaths (estimates vary considerably across sources).

Key Figures at a Glance

MCQ Traps

• The 3rd June Plan is also known as the Mountbatten Plan — both names refer to the same document, a commonly tested equivalence.
• The Radcliffe boundary award was published on 17 August 1947, two days AFTER independence (15 August) — a frequently tested, striking fact about the chaotic transition.
• Sir Cyril Radcliffe had no prior experience of India and was given only about five weeks to demarcate both the Punjab and Bengal boundaries — a key basis for later criticism of the process.
• NWFP's decision was made via referendum; Sindh's via legislative assembly vote; Balochistan's via the Shahi Jirga — three distinct mechanisms for three different regions, frequently tested together.
• The Indian Independence Act formally ended British paramountcy over princely states, but did not force them to join either dominion — their accession decisions (including contested cases like Kashmir, Hyderabad, and Junagadh) became a major, separate post-independence issue.

Model Answer Outline

Q. Discuss the 3rd June Plan and the Indian Independence Act 1947, and critically evaluate the Radcliffe boundary demarcation process.

1. Introduction: Mountbatten's appointment and the context following the Cabinet Mission Plan's collapse.
2. The 3rd June Plan: partition principle, mechanisms for Punjab/Bengal/Sindh/NWFP/Balochistan, and princely state accession.
3. The Indian Independence Act: its legal provisions and the creation of the two dominions.
4. The Radcliffe Commission: its composition, extremely compressed timeframe, and the criticism of its process and outcome.
5. Consequences: mass migration, communal violence, and the chaotic, border-uncertain transition.
6. Conclusion: while the plan resolved the immediate constitutional deadlock, its rushed implementation contributed significantly to the human cost of partition.

60-Second Revision

March 1947: Mountbatten appointed last Viceroy, concludes united India is untenable given communal violence • 3 June 1947: the 3rd June/Mountbatten Plan announced — partitions British India into India and Pakistan; Punjab and Bengal assemblies vote on partition; Boundary Commission to demarcate borders; Sindh's assembly votes for Pakistan; NWFP referendum favours Pakistan (Khudai Khidmatgar/Congress-aligned leadership boycotts); Balochistan's Shahi Jirga + Quetta Municipality opt for Pakistan; princely states free to accede to either dominion; transfer of power set for 15 August 1947 • Both Congress and League accept — first mutual agreement on partition as the solution • Indian Independence Act (July 1947): creates the two dominions, ends British paramountcy over princely states, divides assets/liabilities/armed forces, each dominion uses the 1935 Act as provisional constitution • Radcliffe Boundary Commission: chaired by Sir Cyril Radcliffe (no prior India experience), ~5 weeks to demarcate Punjab and Bengal; Radcliffe Line published 17 August — TWO DAYS after independence, leaving both countries briefly without known borders • Consequences: ~10-15 million displaced, massive communal violence, widely criticised as a rushed, poorly-informed process
