Introduction

Preventive detention aims to prevent potential threats to the State or public order rather than punish individuals. To avoid misuse, the Constitution provides specific safeguards to protect detainees’ rights.

Meaning / Definition

• Preventive Detention: Detaining a person to prevent them from committing acts that may harm the State, public order, essential services, or foreign relations.
• It is preventive in nature and not a form of punishment.

Modes or Types

Grounds for Preventive Detention

Preventive detention can be ordered only on the following grounds:

• Security of the State: To prevent actions threatening national security.
• Maintenance of Public Order: To stop disturbances that can harm public peace.
• Essential Services and Defense: To protect supplies, essential services, and defense operations.
• Foreign Affairs or Security of India: To safeguard India’s international interests and security.

Important Case Law

• Mariappan v District Collector and Others – The court held that the object of detention laws is preventive, not punitive, and aims to stop the commission of certain offences.

Safeguards Provided in Constitution

To minimize abuse, the Constitution provides certain safeguards:

• Advisory Board Review: Initial preventive detention can last up to 3 months. Extension beyond 3 months requires approval from an Advisory Board of High Court-qualified members.
• Right to Know Grounds: The detainee is entitled to know the reasons for detention, except when disclosure is against public interest.
• Opportunity for Representation: Detainees must be given the earliest opportunity to make a representation against their detention.

These safeguards do not apply to enemy aliens.

Practical Example

• A person suspected of plotting acts against public order can be detained preventively. Their detention is initially limited to 3 months unless approved by an Advisory Board. They can know the general grounds and make representation against the detention.

Summary

• Preventive detention prevents potential harm to the State or society, not punishment.
• Only four grounds are valid: security of the State, public order, essential services/defense, and foreign affairs/security of India.
• Article 19 and 21 rights may not apply to preventive detainees.
• Constitutional safeguards include limited detention period, Advisory Board approval, knowledge of detention grounds, and opportunity to make representation.
• Safeguards do not apply to enemy aliens.
