What do you mean by Rowlatt Act?
The Rowlatt Act was a law passed by the British in colonial India in March 1919, indefinitely extending "emergency measures" enacted during the First World War in order to control public unrest and root out conspiracy. Passed on the recommendations of the Rowlatt Committee, named for its president, British judge Sir Sidney Rowlatt, this act effectively authorized the government to imprison for a maximum period of two years, without trial, any person suspected of terrorism living in the Raj. The Rowlatt Act gave British imperial authorities power to deal with revolutionary activities.
