Detention vs Arrest: Extent and Limits of Police Powers

The issue came into focus after Rahul Gandhi and several Opposition leaders were detained by Delhi Police during protests in New Delhi over alleged irregularities in the Election Commission’s Special Intensive Revision (SIR) exercise.The incident revived questions over the legal difference between detention and arrest and the limits of police powers during protests.

Detention vs Arrest

• Arrest is a formal act of taking a person into custody in connection with an offence and triggers criminal proceedings and constitutional safeguards.
• Detention may involve temporary restraint or custody, often for maintaining law and order or preventing an offence, without necessarily resulting in formal arrest.
• The BNSS does not separately define “detention”, but grants police preventive powers in specified circumstances.
• Temporary custody during protests is different from statutory preventive detention, which permits detention without trial under special laws such as the National Security Act.

Preventive Powers under BNSS

• Section 170, BNSS: Police may arrest without warrant to prevent the commission of a cognisable offence when it cannot otherwise be prevented.
• Section 172, BNSS: Police may detain or remove a person who resists, refuses, ignores or disregards a lawful police direction.
• Such a person must ordinarily be produced before a Magistrate within 24 hours, unless released earlier in a petty case.

When Can Police Detain Protesters?

• Police may temporarily restrain protesters to prevent an imminent law-and-order disturbance.
• If a prohibitory order under Section 163 of BNSS is in force, police may remove persons who refuse to comply.
• Continued disobedience may amount to an offence under the Bharatiya Nyaya Sanhita (BNS) and can result in formal arrest and registration of an FIR.
• Police action cannot be arbitrary and must be justified as necessary and proportionate.

Rights of a Detained or Arrested Person

• Article 22 protects individuals against arbitrary arrest and detention.
• A person must be informed of the grounds of arrest.
• The arrested person has the right to consult and be defended by a legal practitioner.
• The person must be produced before a Magistrate within 24 hours.
• The Supreme Court has emphasised that grounds of arrest must be properly communicated to the accused.

Key Supreme Court Rulings

• Joginder Kumar v. State of U.P. (1994): Mere existence of the power to arrest does not justify its exercise; an arrest must be necessary and justified.
• Arnesh Kumar v. State of Bihar (2014): Police should not make automatic arrests, particularly for offences punishable with imprisonment of up to seven years.
• Mazdoor Kisan Shakti Sangathan v. Union of India (2018): Restrictions on protests should be regulatory rather than aimed at eliminating the right to protest.

Detention is generally temporary and preventive, while arrest formally places a person in criminal custody. Both are subject to constitutional safeguards, and police powers must satisfy the tests of legality, necessity and proportionality.
