The Simon Commission, officially known as the Indian Statutory Commission, was appointed in November 1927 by the British government [1]. Its primary mandate was to review the working of the Government of India Act, 1919 (also known as the Montagu-Chelmsford Reforms) and report on the progress of the constitutional system [2]. The 1919 Act had specifically provided for the appointment of a Royal Commission ten years after its enactment to evaluate its performance and recommend further reforms [1][t2]. Although scheduled for 1929, the commission was appointed two years early by Lord Birkenhead to assess the effectiveness of diarchy and the transition toward responsible government [c2][t9]. The commission's findings eventually influenced the subsequent Round Table Conferences and the drafting of the Government of India Act, 1935 [c1].
