Phase IFoundation

Background

Overview

UPSC frequently examines the delicate balance between state security/public order and individual liberties, the constitutional provisions related to fundamental rights, and the role of the judiciary in upholding them. Preventive detention is a critical area where these tensions are evident, making its legal framework, safeguards, and potential for misuse highly relevant.

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 or national security. Unlike punitive detention, which punishes for past offenses, preventive detention aims to prevent future harm.

Facts & tables

Key facts

Constitutional Basis

Article 22 of the Indian Constitution provides safeguards against arbitrary arrest and detention, including specific provisions for preventive detention.

Purpose

To prevent individuals from committing certain offenses or acting against public order/security, rather than to punish them for past actions.

Safeguards

Detained persons must be informed of the grounds for detention, allowed representation, and detention beyond 2-3 months requires review by an Advisory Board.

Legislative Power

Both Parliament and State Legislatures are empowered to enact laws for preventive detention under the Seventh Schedule of the Constitution.

Nature of Detention

Allows detention without trial or formal charges, based on apprehension.

Nature

Detention without trial, based on suspicion, not conviction

Grounds for Detention

Primarily 'public order' and 'security of the state', which are distinct from ordinary 'law and order' issues, as clarified by the Supreme Court.

Duration and Review

Detention can be for up to one year for public order and two years for security of the state under laws like PSA, subject to review by an Advisory Board.
