The correct answer is the Rowlatt Act. About the Rowlatt Act: • The Rowlatt Act was passed in by the recommendations of Sir Sidney Rowlatt in 1919 and became law in March 1919. Mahatma Gandhi said the Bill or Act was Black-Bill or Black Act. • the protests became more aggressive and vocal, especially in the Punjab region, where all communication systems such as Railway and the Telegraph services were disrupted. • The "Rowlatt Act" came up against the Indians and it simply means that without any trials or proceedings they would be arrest and face deportation of any person on mere Suspicion of Sedition and Revolt in the region. • Two of the most visible faces of this protest were Dr. Saifuddin Kitchlew and Dr. Satya Pal were taken into custody by the Police and secretly transported away from the area. • For against these two arrests and dominance of the Rowlatt Act, Mahatma Gandhi started a Strike against this arrest. • However, as the movement started by Gandhi came to be known, the "Rowlatt Satyagraha" left the British totally unmoved as they did not see the peaceful 'hartal' as a threat. Notes: • Lord Chelmsford was the Governor-General of India during the formation of the Rowlatt Act in 1919.
