The Anarchical and Revolutionary Crimes Act of 1919, popularly known as the Rowlatt Act, was a law that applied in British India. It was a legislative council act passed by the Imperial Legislative Council in Delhi on 18 March 1919, indefinitely extending the emergency measures of preventive indefinite detention, imprisonment without trial and judicial review enacted in the Defence of India Act 1915 during the First World War. It was enacted in the light of a perceived threat from revolutionary nationalists of re-engaging in similar conspiracies as had occurred during the war which the Government felt the lapse of the Defence of India Act would enable. Purpose and introduction The British Colonial Government passed the Rowlatt Act which gave powers to the police to arrest any person without any reason. The purpose of the Act was to curb the growing nationalist upsurge in the country. Mahatma Gandhi called upon the people to perform satyagraha against the act. Passed on the recommendations of the Rowlatt Committee and named after its president, Sir Sidney Rowlatt, the act effectively authorized the colonial British government to imprison any person suspected of terrorism living in British India for up to two years, and gave the colonial authorities power to deal with all revolutionary activities. The unpopular legislation provided for stricter control of the press arrests without warrant, indefinite detention without trial, and juryless in camera trials for proscribed political acts The accused were denied the right to know the accusers and the evidence used in the trial. Those convicted were required to deposit securities upon release, and were prohibited from taking part in any political, educational, or religious activities. On the report of the committee, headed by Justice Rowlatt, two bills were introduced in the Central Legislature on 6 February 1919. These bills came to be known as "Black Bills". They gave enormous powers to the police to search a place and arrest any person they disapproved of without warrant. Despite much opposition, the Rowlatt Act was passed on 18 March 1919. The purpose of the act was to curb the growing nationalist upsurge in the country. Under the Rowlatt act 1919, the chief justice was empowered to decide on the immediate custody of the accused between the trial and release on bail for smooth implementation of the act. The act also provides a penalty for disobedience of any order promulgated under sections 22 and
