The Muddiman Committee Report officially known as the Report of the Reforms Enqury Committee, 1924 was the product of the Government of India Act, 1919. After the committee was put into operation, resolutions were pressed in the Imperial legislature, especially led by the Swarajists for the revision of the constitution to secure for India full self-governing Dominion status. Plagued by such Indian demands, the Government of India set up a Committee under the Chairmanship of Sir Alexander Muddiman. The nine member Committee's terms of reference were: to enquire into the difficulties arising from, or defects inherent in, the working of the Government of India Act and the Rules thereunder in regard to Central Government and the governments of Governors' provinces; to investigate the feasibility and desirability of securing remedies for such difficulties or defects, consistent with the structure, policy and purpose of the Act, or by such amendments of the Act as appear necessary to rectify any administrative imperfections. The Committee rather expeditiously completed its work between August and December 1924. The Committee submitted its report in September 1925. Its appendices contained a list of public leaders and individuals who had tendered evidences to the Committee; memorandum of the legal and constitutional possibilities of advance within the Government of India Act; and a lengthy note by a member Bijoy Chand Mahtab.
The Muddiman Committee did not submit a unanimous report. The majority view was that the existing constitution was working in most provinces and was affording valuable political experience. Detailed recommendations were made for improving machinery of government. The minority view was that diarchy had absolutely failed and could not succeed at all in the future. According to them, it was only a fundamental change in the constitution, which could bring about the improvement.
