I am studying the Cabinet Mission Plan of 1946 for UPSC, and I can follow its proposal for a limited Union government. What I cannot quite understand is why the grouping of provinces became such a major point of disagreement between Congress and the Muslim League.
Accounts often describe the dispute as compulsory versus optional grouping. That sounds straightforward until they also mention a province's ability to leave a group later.
- Did the plan distinguish between joining the initial constitution-making sections and remaining in the resulting groups?
- At what stage was a province supposed to be able to opt out, and who would make that decision?
- Why was this distinction particularly significant for Assam and the North-West Frontier Province?
Could someone explain the sequence using the plan's provisions, while separating those provisions from the interpretations advanced by Congress and the League? I want to avoid reducing the disagreement to a one-line exam note that misses the constitutional issue.
