Asked by a reader in Bengaluru

Can the police stop a peaceful protest or detain protesters?

A peaceful protest can still be subject to lawful restrictions. Ask which written order or legal power is being enforced and record the time if you are taken into custody. Section 163 BNSS permits specified urgent prohibitory orders, while Section 170 allows preventive arrest only where the anticipated cognizable offence cannot otherwise be prevented. That arrest cannot exceed 24 hours without another lawful basis. Challenge the order or detention through the proper process. Avoid assuming either protest or police action is automatically unlawful.

Three separate legal instruments get used at protests, and knowing which one is being applied is the difference between an argument that goes somewhere and one that does not. Ask the officer, calmly, which of the three he is acting under.

The starting point is the right, not the power

Article 19(1)(a) of the Constitution guarantees freedom of speech and expression, Article 19(1)(b) the right to assemble peaceably and without arms, and Article 19(1)(d) the freedom to move throughout India. In August 2016 the Supreme Court, dealing with police action against a demonstration, said that holding a peaceful demonstration to air grievances and be heard is the right of the people, and traced it to those freedoms. In July 2018 it examined repeated blanket prohibitory orders that had turned a whole area into a place where no peaceful protest could be held. The rights are not absolute, and Article 19(2) and Article 19(3) allow reasonable restrictions, but the starting position is a protected freedom that has to be justified away.

Instrument one: a prohibitory order

Under the Bharatiya Nagarik Suraksha Sanhita, 2023, a District Magistrate, a Sub-divisional Magistrate or a specially empowered Executive Magistrate may, by a written order stating the material facts, direct a person to abstain from a certain act where the Magistrate considers the direction likely to prevent obstruction, annoyance or injury to a person lawfully employed, danger to human life, health or safety, a disturbance of the public tranquillity, a riot or an affray. Five features are worth remembering at the spot.

  • It is made by a Magistrate, not by a police officer.
  • It must be in writing and must state the material facts.
  • It may be directed to an individual, to persons residing in a particular place or area, or to the public generally when frequenting or visiting a particular place, and may be passed ex parte in an emergency.
  • No order remains in force for more than two months, extendable by the State Government by notification for a further period not exceeding six months for the specified reasons.
  • Any Magistrate may rescind or alter such an order on his own motion or on the application of a person aggrieved, and where such an application is received the applicant must be given an early opportunity of appearing and showing cause, with reasons recorded in writing if the application is rejected.

Instrument two: unlawful assembly

The Bharatiya Nyaya Sanhita, 2023 designates an assembly of five or more persons unlawful if the common object is one of five listed objects: to overawe by criminal force the Government, a Legislature or a public servant in the exercise of lawful power; to resist the execution of any law or legal process; to commit mischief, criminal trespass or another offence; to take possession of property or enforce a right or supposed right by criminal force; or to compel a person by criminal force to do what he is not legally bound to do. An explanation adds that an assembly which was not unlawful when it assembled may become so. Note what is absent from that list: a peaceful gathering to express a grievance is not there.

Instrument three: preventive arrest

The Sanhita allows a police officer who knows of a design to commit a cognizable offence to arrest the person so designing, without a warrant and without an order from a Magistrate, if it appears that the commission of the offence cannot otherwise be prevented. It then fixes the ceiling: no person so arrested shall be detained beyond twenty four hours from the time of arrest unless further detention is required or authorised under some other provision of the Sanhita or of any other law. This is the provision under which protesters are commonly taken to a station and released the same evening.

Preventive arrest is not preventive detention.
A preventive arrest under the Sanhita is a short police power capped at twenty four hours. Detention under a preventive detention law is a different regime, with its own constitutional safeguards, advisory boards and periods, and our guide on preventive detention in India explains that framework. If someone is held for days, ask under which law, because it is not the provision described above.

What to do at the spot and afterwards

  1. Ask which order is being enforced, its date, the authority that made it, and the area it covers. A prohibitory order exists on paper.
  2. Ask under what provision you are being taken, and note the time. If it is a preventive arrest, note the twenty four hour ceiling from that time.
  3. Record. Note the officers present, keep the phone recording where you safely can, and write the account down the same day.
  4. Challenge the order where it is unjustified. The Sanhita itself allows an application to the Magistrate to rescind or alter the order, with a right to be heard; and where that fails, the High Court is available, as our guide on filing a writ petition in the High Court explains.
  5. Deal with any case registered afterwards on its own terms. Speech based cases arising out of banners, slogans and placards raise their own questions, and our note on a first information report over a banner and the free speech defence works through them.

Force, and the limits on it

Where a gathering does become unlawful, the Sanhita contains provisions for its dispersal, and the use of force there is regulated rather than unlimited. Excessive force against persons who are not resisting is separately actionable, and that allegation belongs before the human rights commission and the writ court rather than in the criminal trial. Photograph injuries, get a medical record made the same day, and preserve any video.

Police Powers & Citizens' Rights

The police detained me overnight without arresting me. Was that lawful?

Being called for questioning does not give police an unlimited power to keep you overnight. Ask whether you are free to leave and which legal power is being used. Arrest brings safeguards, including reasons and timely production before a Magistrate. The BNSS also contains specific preventive detention or removal powers, so the label alone does not settle legality. Record the times, officers and any notice or order, and get urgent help if you remain unlawfully confined.

Police Powers & Citizens' Rights

I was not produced before a magistrate within 24 hours. What is the remedy?

Police cannot ordinarily keep an arrested person beyond 24 hours without a Magistrate's authority, excluding the necessary journey time. Sections 58 and 187 BNSS govern this limit and further remand. Raise the actual arrest time and production time before the court immediately. Request the custody records. If someone is still unlawfully detained, urgent court intervention may be necessary. A breach needs to be challenged, but it does not automatically erase the underlying criminal allegations.

Police Powers & Citizens' Rights

How do I complain against a police officer in Karnataka?

Choose the route by the misconduct. Send a documented complaint to the senior police officer. Allegations of an offence may also require a criminal complaint and, where appropriate, a Magistrate's application. The Karnataka State Human Rights Commission can examine qualifying human rights violations. Record dates, names, injuries and documents, and keep proof of submission. Special safeguards apply to court-directed investigation of complaints concerning a public servant's official duties, so avoid assuming every complaint follows an identical procedure.

Police Powers & Citizens' Rights

Can I claim compensation for illegal detention?

Compensation may be available for a clearly established, serious violation of personal liberty. An acquittal alone does not prove detention was unlawful. A writ court can award public-law compensation in qualifying cases, while other remedies depend on the facts. Preserve the arrest and remand papers, medical records and evidence of the custody period. There is no guaranteed amount. If detention continues, obtaining release or urgent judicial scrutiny matters more immediately than estimating damages.

Police Powers & Citizens' Rights

I was never told why I was being arrested. What are my rights?

You are entitled to know the grounds of your arrest. Section 47 BNSS requires the arresting officer to communicate the full particulars of the offence or other grounds promptly. Simply leaving you to guess from a case number is not the safeguard the provision describes. Ask for the arrest papers and tell your lawyer what you were actually told. Raise the failure before the Magistrate at first production and ask that your objection be recorded.

Police Powers & Citizens' Rights

The police refused to let me call my family or a lawyer. What can I do?

Tell the Magistrate at first production and ask for the refusal to be recorded. Section 48 BNSS requires the police to inform a relative, friend or other nominated person of the arrest and place of custody. Section 38 gives an arrested person access to an advocate during interrogation, though not throughout it. Keep a note of whom you asked to contact, when you asked and the response. These details help establish what safeguard was denied.
