Context: The Delhi Police detained over 5,000 protesters seeking the resignation of the Chief Election Commissioner and rollback of the Special Intensive Revision (SIR) of electoral rolls. On October 11, 2026, the Supreme Court directed the Centre and Delhi Police to prevent unlawful detentions and ensure the free movement of people, subject to law and public order.

What is Preventive Detention?

• Preventive detention is the detention of a person without trial or conviction to prevent a potential future offence, rather than to punish a past offence. It may be invoked on grounds relating to public order, State security and other legally specified threats.
• National Security Act (NSA), 1980: Allows preventive detention when the government is satisfied that a person's activities may prejudice the defence of India, relations with foreign powers or the security of the State.

Preventive Detention vs Prohibitory Orders

• Section 163 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023: Empowers a District Magistrate, Sub-Divisional Magistrate or other specially empowered Executive Magistrate to issue urgent orders to prevent obstruction, danger to human life, health or safety, disturbance of public tranquillity, riots or affrays.
• Nature of prohibitory orders: These are preventive measures intended to avert imminent harm, not to punish past acts. Orders may be issued without prior notice where urgency demands, but must state the material facts and remain subject to judicial scrutiny.
• Key distinction: Preventive detention restricts an individual's liberty through detention, whereas a prohibitory order generally restricts specified activities, movement or assembly to prevent an anticipated threat.

Evolution of Preventive Detention in India

• Colonial period: The Rowlatt Act, 1919, and Defence of India Act, 1939, enabled detention without trial and were used against freedom fighters and political opponents.
• Post-Independence: The Preventive Detention Act, 1950, remained in force until 1969.
• Emergency period: The Maintenance of Internal Security Act (MISA), 1971, expanded detention powers and was widely used against political opponents during the Emergency (1975–1977); it was repealed in 1978.
• Current legal framework: The NSA, 1980, continues to provide for preventive detention. The Conservation of Foreign Exchange and Prevention of Smuggling Activities Act (COFEPOSA), 1974, also permits detention for specified purposes.
• Anti-terrorism framework: Amendments to the Unlawful Activities (Prevention) Act (UAPA), 1967, have expanded State powers to address terrorism and unlawful activities.
• Personal liberty jurisprudence: In Maneka Gandhi v. Union of India (1978), the Supreme Court established that procedures restricting personal liberty must be just, fair and reasonable.

Supreme Court Directions on the Delhi Protests

• Freedom of movement: On October 11, 2026, the Supreme Court directed the Union government and Delhi Police to prevent illegal detentions and ensure the free movement of people and traffic, subject to law and public order.
• Essential services and access: The Court directed normal Metro and railway operations, lawful availability of internet services, and review of barricades based on law-and-order and traffic requirements.
• Peaceful assembly: Peaceful protests must be allowed in accordance with law, except in areas where valid prohibitory orders under Section 163 of the BNSS apply.
• Professional duties: The Court recorded assurances that lawyers, journalists and other professionals would not be prevented from performing their duties.
• Judicial accountability: The Court issued notice in contempt proceedings concerning alleged violation of its October 9 order and directed submission of a compliance report by October 13. Habeas corpus petitions alleging mass detentions were also scheduled for hearing.
• Article 32: The Court emphasised its constitutional duty to protect fundamental rights and required the State to explain the circumstances and legal basis of the alleged detentions.

Important Supreme Court Judgments

• Babulal Parate v. State of Maharashtra (1961): Upheld the constitutional validity of Section 144 of the CrPC, while recognising that such powers must operate within legal limits and address specific threats to public order.
• Khudiram Das v. State of West Bengal (1975): Emphasised that communicating the grounds of detention acts as a safeguard against arbitrary exercise of power and enables the detainee to make a representation and seek judicial review.
• Ramlila Maidan Incident (2012): The Supreme Court held that Section 144 should be used only in grave and urgent circumstances requiring immediate preventive action.
• Mazdoor Kisan Shakti Sangathan v. Union of India (2018): Set aside a blanket ban on protests at Jantar Mantar Road and favoured regulating demonstrations rather than prohibiting them altogether.
• Shaik Naznen v. State of Telangana (2022): Observed that preventive detention powers are exceptional and must not be exercised routinely.
• Ameena Begum v. State of Telangana (2023): Emphasised the need to enforce constitutional safeguards under the Articles 14, 19 and 21 framework, often called the constitutional “golden triangle”.

Constitutional Safeguards Against Preventive Detention

• Article 22(4): Generally restricts preventive detention beyond three months without review by an Advisory Board, subject to constitutional provisions and exceptions.
• Article 22(5): Requires authorities to communicate the grounds of detention as soon as possible and provide an opportunity to make a representation against the detention order.
• Article 14: Guarantees equality before the law and protection against arbitrary State action.
• Article 19: Protects freedoms including speech and expression, peaceful assembly and movement, subject to constitutionally permitted restrictions.
• Article 21: Protects life and personal liberty, requiring deprivation of liberty to follow a procedure established by law.
• Judicial review: Courts can examine compliance with legal and constitutional requirements, including whether detention was based on relevant material and whether mandatory safeguards were followed.

Key Challenges

• Potential misuse: Broad discretionary powers may be used against protesters, political opponents and other individuals without adequate justification.
• Prolonged detention without trial: Preventive detention can seriously affect personal liberty, particularly where judicial scrutiny is delayed.
• Conflict with democratic freedoms: Excessive restrictions on protests may undermine freedom of expression, peaceful assembly and democratic accountability.
• Need for proportionality: Authorities must distinguish genuine threats to public order from peaceful dissent and use the least restrictive effective measures.

Way Forward

• Strict application of safeguards: Ensure timely communication of detention grounds, effective representation and meaningful judicial review.
• Proportionate restrictions: Use preventive detention and prohibitory orders only when legally justified, necessary and proportionate to the threat.
• Protect peaceful protests: Prefer regulated demonstrations and targeted restrictions over blanket prohibitions.
• Strengthen accountability: Require clear reasons for detention, transparent records and prompt judicial scrutiny of alleged unlawful detention.
