- The Central Industrial Security Force (CISF) is an armed force of the Union, established under the CISF Act, 1968. - Members of armed forces of the Union are typically excluded from the purview of general labour laws such as The Payment of Wages Act, 1936, The Industrial Disputes Act, 1947, and The Factories Act, 1948. Their service conditions, discipline, and other related matters are governed by their specific Acts and Rules. - Article 33 of the Constitution allows Parliament to modify or abrogate fundamental rights for members of armed forces, including those related to freedom of association and other rights that labour laws are based on. - The Indian Penal Code, 1860 (IPC) is a general criminal law that applies to all persons in India, including members of the CISF, unless specific exceptions are made for acts done in the discharge of their official duty (which are often covered by provisions within the CISF Act or CrPC, but the IPC itself is not rendered inapplicable to them).
