Normally, a person is arrested after committing a crime. But the law also allows the State to detain a person before a crime happens, if it believes the person may act against public order or national security. This is called preventive detention. Since it can be misused, the Constitution gives safeguards in Article 22. Exams ask about the rights of arrested persons, the three-month rule, the Advisory Board and laws like the NSA. This post explains them in simple words. It ends with 15 previous year questions.
Key Points (Quick Revision)
- Article 22 gives protection against arrest and detention in certain cases.
- An arrested person must be produced before a magistrate within 24 hours, excluding travel time.
- Under preventive detention, a person can be held for up to three months without an Advisory Board's approval.
- Only Parliament can make preventive detention laws on defence, foreign affairs and security of India.
- The National Security Act, 1980 allows detention for up to 12 months.
1. Two kinds of detention
| Point | Punitive detention | Preventive detention |
|---|---|---|
| Purpose | To punish a crime already committed | To prevent a possible future act |
| Basis | Trial and conviction in court | Suspicion that the person may harm public order or security |
| Trial | Yes | No trial; review by an Advisory Board |
2. Rights of an arrested person (Article 22(1) and (2))
A person arrested under ordinary law has the right:
- To be informed of the grounds of arrest as soon as possible.
- To consult and be defended by a lawyer of his or her choice.
- To be produced before the nearest magistrate within 24 hours, excluding the time of journey.
- Not to be kept in custody beyond 24 hours without the magistrate's order.
These rights do not apply to an enemy alien or to a person detained under a preventive detention law.
3. Safeguards in preventive detention (Article 22(4) to (7))
- Detention beyond three months needs a report from an Advisory Board of persons qualified to be High Court judges, saying there is sufficient cause.
- The detained person must be told the grounds of detention, though facts against public interest need not be disclosed.
- The person must get the earliest chance to make a representation against the order.
- Parliament can fix the maximum period of detention and the procedure of the Advisory Board.
The 44th Amendment (1978) sought to cut the period without Advisory Board review from three months to two months, but this part has not been brought into force.
4. Who can make preventive detention laws?
| Grounds | Who can make the law |
|---|---|
| Defence, foreign affairs, security of India | Parliament only (Union List) |
| Security of a State, public order, supply of essential goods and services | Parliament and State Legislatures (Concurrent List) |
5. Important preventive detention laws
| Law | Year | Status / purpose |
|---|---|---|
| Preventive Detention Act | 1950 | The first such law; lapsed in 1969 |
| MISA (Maintenance of Internal Security Act) | 1971 | Widely used during the Emergency; repealed in 1978 |
| COFEPOSA | 1974 | Prevents smuggling and foreign exchange violations |
| National Security Act (NSA) | 1980 | Detention up to 12 months for threats to security or public order |
| PITNDPS Act | 1988 | Prevents illicit traffic in narcotic drugs |
Many States also have their own laws, for example against habitual offenders, under the Concurrent List.
6. Court rulings
- A.K. Gopalan case (1950) - the Supreme Court read Articles 21 and 22 narrowly and upheld preventive detention.
- Maneka Gandhi case (1978) - held that any procedure that takes away liberty must be fair, just and reasonable, widening the protection of Article 21.
- Courts have often set aside detention orders where grounds were vague, supplied late, or where ordinary law could have dealt with the matter.
7. Debate
Supporters say preventive detention is needed to stop terrorism, communal violence and smuggling before harm is done. Critics point out that India is among the few democracies that allow it in peacetime, and that it can be misused against political opponents and journalists. The safeguards of Article 22 and strict court review try to balance liberty and security.
