Why was the Simon Commission, established in 1927, boycotted by the Indian National Congress?

The Simon Commission, also known as the Indian Statutory Commission, consisted entirely of British members, with no Indian representation. This exclusion was seen as a direct affront to Indian self-respect and an attempt to undermine the demand for self-governance. The Indian National Congress formally decided to boycott the commission during its Madras session in 1927. The absence of Indian members highlighted the colonial disregard for Indian aspirations for autonomy.
