Karnataka Right to Know Grounds of Arrest Laws (2026)
About this article
Sourced from Indian central (Union) law — Constitution of India, central Acts of Parliament, and Supreme Court decisions. State-level information reflects each state's own Acts and High Court rulings. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
The reason for your arrest is not optional information the officer can hold back — it is a constitutional entitlement that triggers the moment cuffs go on.
- Article 22(1) of the Constitution: no one may be detained without being informed, as soon as may be, of the grounds for the arrest.
- BNSS s. 47(1): the arresting officer must communicate the full particulars of the offence — not just "You are under arrest."
- BNSS s. 50: the police must also tell the next of kin where you are being held.
- D.K. Basu guidelines (now partly written into BNSS): an arrest memo has to be prepared, signed by you and a witness, and you can name a relative or friend who must be informed.
An arrest where grounds are never communicated is illegal on its face — the High Court (or the Supreme Court) can be moved by writ of habeas corpus to order your immediate production and release.
When does it apply?
- A police officer — Central or State — is putting you under arrest or holding you at the station.
- A family member has been picked up and you want to know what the case actually is.
- You are sitting in a thana and no one will tell you why.
What to Do If Police in India Arrest You Without Explaining the Grounds
Stay calm, but document everything from the first minute.
- Ask the officer plainly: "What is the reason for my arrest?" and make sure the answer goes into the arrest memo.
- Insist that the officer contact your family member or lawyer — BNSS s. 50 makes this their duty, not your favour.
- Read the arrest memo before signing. It must show the date, time and a witness signature.
- If grounds are withheld, get a relative to file a habeas corpus petition in the High Court of the relevant State — the court will summon the police to produce you and justify the detention.
- Call the State Legal Services Authority (SLSA) or NALSA on 15100 — free representation is available, immediately.
What should you NOT do?
- Do not physically resist arrest even when it looks unlawful. Fight it through court — resisting itself is a criminal offence.
- Do not sign blank or partly-filled papers at the police station. Anything signed becomes part of the record.
- Do not give a statement after a formal arrest without your lawyer in the room.
How Karnataka differs from central law
The constitutional right to know the grounds of arrest applies uniformly across India. Karnataka-specific aspects relate to the Karnataka Police Act, 1963 and the Commissioner system in Bengaluru.
- Karnataka Police Act, 1963: This Act governs the organisation and powers of the Karnataka police force. Police officers must follow the D.K. Basu guidelines and BNSS provisions on arrest procedures, including preparing an arrest memo with date, time, and grounds.
- Bengaluru City Police: Bengaluru operates under a Police Commissioner system (not the Superintendent of Police system used in other Karnataka districts). The Commissioner of Police, Bengaluru City has wider powers, including the power to issue prohibitory orders under Section 163 of BNSS.
- Goondas Act preventive detention: Under the Karnataka Prevention of Dangerous Activities Act, 1985 (Goondas Act), the Police Commissioner (in Bengaluru, Mysuru, and other Commissionerate cities) or District Magistrate can order preventive detention of up to 12 months for persons classified as bootleggers, drug offenders, goondas, or slum grabbers. The detenue must be informed of the grounds of detention within 5 days and has the right to make a representation to the Advisory Board.
- Arrest information: The Karnataka State Legal Services Authority (KSLSA) has directed that every police station in Karnataka must prominently display the arrested person's rights, including the right to know grounds of arrest, right to legal counsel, and right to inform family.
Additional Steps in Karnataka
If arrested without being told the grounds, demand the arrest memo and contact a lawyer or the KSLSA helpline (1516). For Goondas Act detentions, the detenue's family should immediately consult a lawyer and file a representation before the Advisory Board within the prescribed time.
Relevant Law: Karnataka Police Act, 1963; Karnataka Prevention of Dangerous Activities of Bootleggers, Drug-Offenders, Gamblers, Goondas, Immoral Traffic Offenders and Slum Grabbers Act, 1985 (Goondas Act); BNSS, 2023, ss. 47-48
