The Official Secrets Act of 1923 is India's anti-espionage act held over from the British colonial period. It states clearly that actions which involve helping an enemy state against India are strongly condemned. It also states that one cannot approach, inspect, or even pass over a prohibited government site or area like an electrical substation. According to this Act, helping the enemy state can be in the form of communicating a sketch, plan, model of an official secret, or of official codes or passwords, to the enemy.
