An official notification has extended the Delhi Police power of preventive detention under the National Security Act, 1980 until 18 October 2026. The extension matters because preventive detention sits at the intersection of internal security, policing, and civil liberties.

Delhi Police has described the extension as a routine administrative step and has denied media reports that linked the move to the CJP-led protest. The extension continues the existing preventive detention power and does not create a new legal authority.

Background and earlier position

The National Security Act, 1980 permits authorities to detain a person preventively to stop conduct considered harmful to the defence of India, public order, or essential services. Preventive detention is distinct from ordinary criminal detention because it is designed to prevent anticipated harm rather than punish an already committed offence.

In Delhi, preventive detention powers have been treated as an instrument of public order and security administration under the city’s special constitutional and administrative framework. The present extension continues that framework rather than creating a new power.
