"Preventive detention is a necessary evil in a democracy." Critically examine with reference to Article 22 and judicial safeguards.

Preventive detention means holding a person without trial in order to stop a feared future act, not to punish a past one [4]. Few democracies do this, but Article 22(3)–(7) allows it even in peacetime [1]. It is necessary against real security threats. It becomes an evil when it is used for routine crime or to stop dissent.

Why it is necessary

• Security gap: a trial deals with harm after it happens, while terrorism, smuggling and organised crime need to be stopped beforehand. This is why laws like the NSA 1980 and COFEPOSA 1974 exist.
• Safeguards in the Constitution: an Advisory Board of persons qualified to be High Court judges must approve any detention beyond three months. The detainee must be told the grounds and given a chance to make a representation [1].
• Judicial tightening: Maneka Gandhi (1978) requires any procedure to be just, fair and reasonable. Ram Manohar Lohia (1966) held that "public order" is narrower than "law and order". The SC has also held that Advisory Boards must examine whether a detention is lawful, not approve it mechanically (Nenavath Bujji, 2024) [3].

Why it remains an evil

• Weak protection in Art. 22 itself: the rights to a lawyer and to production before a magistrate within 24 hours do not apply to preventive detainees. Facts can also be withheld "in public interest" [1]. The 44th Amendment's two-month limit has never been notified.
• Routine misuse: the SC said this "extraordinary measure" has become ordinary through "reckless invocation". It held detention unlawful where the ordinary criminal law was enough (Ameena Begum, 2023) [2]. State Goondas Acts now cover bootleggers and drug offenders [5].
• Remedy comes too late: habeas corpus works only after liberty is lost. ADM Jabalpur (1976) showed that courts can fail, until Puttaswamy (2017) overruled it.
• Chilling effect on dissent: in October 2026, Delhi Police detained more than 5,000 protesters, some at their homes before any gathering began [4]. This raises Art. 19(1)(b) concerns.

Preventive detention is therefore a necessary power, and its abuse is what makes it evil. Several steps would help keep it exceptional:

• notify the two-month review limit;
• require written reasons why the ordinary law is not enough;
• provide statutory compensation for illegal detention.

These steps would bring it in line with Article 21's promise of liberty and SDG 16's goal of accountable institutions.
