The National Security Act (NSA) of India allows the central or state government to detain a person to prevent them from engaging in any activity that might jeopardize national security or disrupt public order. The maximum period of detention is 12 months. A person can be held for 10 days without being informed about the charges against them. The extension of detention will take place if the government issues fresh evidence against the individual. The NSA is mentioned in Article 22(3) of the Indian constitution, which allows preventive detention and restriction on personal liberty for reasons of state security and public order. The punishment for committing a crime under the NSA is imprisonment for up to 3 years and/or a fine.
