Preventive Detention

What is Preventive Detention?

Preventive Detention refers to the detention of a person without trial, based on suspicion that they are likely to commit a future offense or to prevent them from acting in a manner prejudicial to public order, security of the state, or maintenance of supplies and services. It is an exceptional measure, distinct from punitive detention which is after a trial and conviction.

Historical Background

Traces back to British colonial laws like the Rowlatt Act 1919. Post-independence, India's Constitution makers included provisions for preventive detention, recognizing the need for state security, but also included safeguards. The first major law was the Preventive Detention Act 1950, which expired in 1969. Subsequent laws include Maintenance of Internal Security Act (MISA) 1971 (repealed in 1978), National Security Act (NSA) 1980, and various state-specific acts like the Goondas Act.
