Public Duty to Assist Magistrates and Police in India: BNSS Sections 31, 32 and 33

Maintaining public order and preventing serious offences are not responsibilities of law-enforcement agencies alone. Indian criminal procedure law specifies when members of the public must assist Magistrates or police officers and when they must report knowledge of particular offences.

Current law: The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), effective from 1 July 2024, replaced the Code of Criminal Procedure, 1973 (CrPC), subject to applicable saving and transitional provisions. The former CrPC Sections 37, 38 and 39 correspond broadly to BNSS Sections 31, 32 and 33.

Section 31 BNSS: When the Public Must Assist Magistrates and Police

Section 31, Bharatiya Nagarik Suraksha Sanhita, 2023 (formerly Section 37 CrPC) requires every person to assist a Magistrate or police officer who reasonably demands such assistance in the following situations:

  1. Lawful arrest: Taking into custody, or preventing the escape of, a person whom the Magistrate or police officer is legally authorised to arrest.
  2. Public peace: Preventing or suppressing a breach of the peace.
  3. Public property: Preventing attempted injury to public property.

The statutory requirement is tied to a reasonable demand by an authorised official. It does not grant unlimited powers to private individuals or justify unsafe, unlawful or disproportionate action.

The former CrPC provision specifically mentioned railway, canal and telegraph property; the present BNSS provision uses the broader expression public property.

Section 32 BNSS: Helping a Person Other Than a Police Officer Execute a Warrant

Section 32 BNSS (formerly Section 38 CrPC) permits another person to assist when a warrant is directed to a person who is not a police officer, provided the person to whom the warrant is directed is near at hand and acting in execution of the warrant.

This is a provision permitting assistance under specified conditions; it is not a general authorisation for a private citizen to execute a warrant independently. The person assisting should verify the official's authority and act within the lawful scope of the warrant.

Section 33 BNSS: Duty to Report Certain Offences

Section 33(1) BNSS (formerly Section 39 CrPC) requires a person who knows of the commission of, or another person's intention to commit, an offence in the categories specifically listed in that section to inform the nearest Magistrate or police officer forthwith, unless the person has a reasonable excuse. The burden of proving such an excuse rests on the person claiming it.

The provision is not a blanket duty to report every possible offence. It expressly refers to the following sections of the Bharatiya Nyaya Sanhita, 2023 (BNS):

  1. Sections 103 to 105.
  2. Sections 111 to 113.
  3. Sections 140 to 144.
  4. Sections 147 to 154 and Section 158.
  5. Sections 178 to 182.
  6. Sections 189 and 191.
  7. Sections 274 to 280.
  8. Section 307.
  9. Sections 309 to 312.
  10. Section 316(5).
  11. Sections 326 to 328.
  12. Sections 331 and 332.

These statutory references cover specified serious offences, including offences against the State, organised crime and terrorism, certain offences affecting life and safety, public tranquillity, robbery, dacoity, counterfeit currency and other expressly enumerated conduct. The precise offence and its ingredients must be checked against the relevant BNS provision.

Section 33(2) also extends the meaning of an offence for this reporting requirement to an act committed outside India which would constitute an offence if committed in India.

How the former CrPC Section 39 differs

Under the earlier Code of Criminal Procedure, Section 39 referred to specified sections of the Indian Penal Code, 1860, including offences against the State, public tranquillity, corruption-related offences, adulteration, offences affecting life, theft with preparation to cause harm, robbery, dacoity, criminal breach of trust, mischief, house-trespass and counterfeit currency. The BNSS now lists BNS section numbers. The older IPC section numbers should not be used as a substitute for the current statutory list.

Practical Guidance for Members of the Public

  • If a Magistrate or police officer reasonably requests help in a situation covered by Section 31, cooperate within lawful and safe limits.
  • If approached to help execute a warrant, establish the identity and authority of the person executing it and ensure the statutory conditions of Section 32 are met.
  • If you have reliable information about a listed offence or an intention to commit it, promptly inform the nearest police officer or Magistrate. Provide accurate facts, available evidence and relevant details.
  • In an immediate emergency, contact the police or the applicable emergency response service. Do not attempt to confront dangerous persons unnecessarily.
  • Do not fabricate allegations, interfere with evidence or circulate unverified accusations.
