Explanation:

The Government of India Act, 1919 was passed to expand participation of Indians in the government of India. The Act embodied the reforms recommended by Edwin Montagu, and the Viceroy, Lord Chelmsford (Montagu-Chelmsford Reforms). The Act covered ten years from 1919 to 1929.

The proposal aims to give in right to self-government or home rule, therefore it was no longer termed as seditious since attainment of self-government for Indians now became a government policy.
