Section 103(2) of the Bharatiya Nyaya Sanhita, 2023, creates India's first specific criminal provision for mob lynching. The Indian Penal Code, 1860, had no standalone offence addressing murder by mobs; such cases were prosecuted under Section 302 (murder) read with Section 34 (common intention) or Section 149 (unlawful assembly). BNS 103(2) establishes that when a group of five or more persons acting in concert commits murder on grounds of race, caste, community, sex, place of birth, language, personal belief, or any other similar ground, each member of the group faces death or life imprisonment plus fine. This provision was introduced in direct response to rising incidents of mob violence across India.

Full statutory text
IPC — No equivalent provision
The IPC had no section specifically addressing mob lynching. Such cases were prosecuted using a combination of:
Section 302 — Whoever commits murder shall be punished with death, or imprisonment for life, and shall also be liable to fine.
Read with Section 34 — When a criminal act is done by several persons in furtherance of the common intention of all, each of such persons is liable for that act in the same manner as if it were done by him alone.
Or Section 149 — If an offence is committed by any member of an unlawful assembly in prosecution of the common object of that assembly, or such as the members of that assembly knew to be likely to be committed in prosecution of that object, every person who, at the time of the committing of that offence, is a member of the same assembly, is guilty of that offence.
Section 103(2) BNS — Murder by group (mob lynching)
(2) When a group of five or more persons acting in concert commits murder on the ground of race, caste or community, sex, place of birth, language, personal belief or any other similar ground, each member of such group shall be punished with death or with imprisonment for life, and shall also be liable to fine.
Key differences
First standalone mob lynching offence: Prior to the BNS, Indian criminal law had no specific offence for mob lynching. The prosecution had to rely on the general murder provision (Section 302 IPC) read with vicarious liability provisions (Section 34 or Section 149 IPC). Section 103(2) BNS eliminates this gap by creating a dedicated offence.
Group threshold of five persons: The provision requires a group of five or more persons acting in concert. This threshold mirrors the requirement for an unlawful assembly under IPC Section 141 and for dacoity under IPC Section 391. Groups of fewer than five persons committing murder would continue to be prosecuted under Section 103(1) BNS read with Section 191 BNS (common intention).
Identity-based motive required: Section 103(2) applies only when the murder is committed on grounds of race, caste, community, sex, place of birth, language, personal belief, or any other similar ground. This is not a general group murder provision — it specifically targets identity-based mob violence. Murders by groups of five or more persons that are not motivated by identity-based grounds do not fall under this sub-section.
Collective liability without Section 34/149: Under the IPC, prosecutors had to establish common intention (Section 34) or common object of an unlawful assembly (Section 149) to hold all members of a mob liable. Section 103(2) BNS creates collective liability directly — each member of the group acting in concert is individually liable for the murder, without requiring the prosecution to separately invoke common intention or unlawful assembly provisions.
"Acting in concert" as the liability standard: The provision uses the phrase "acting in concert," which is distinct from both "common intention" and "common object." This phrase requires coordinated participation in the act of murder but may set a different evidentiary threshold than the established doctrines under Sections 34 and 149 IPC.
"Any other similar ground" — open-ended: The list of grounds concludes with "any other similar ground," creating an open-ended provision that allows courts to extend the protection to identity-based killings motivated by factors not specifically enumerated, such as dietary habits, occupation, or political affiliation.
What this means for practitioners
For prosecution: Section 103(2) BNS simplifies the prosecution of mob lynching cases. Instead of relying on the cumbersome combination of Section 302 read with Section 34 or 149, prosecutors can directly charge under Section 103(2). The prosecution must establish three elements: (a) a group of five or more persons, (b) acting in concert to commit murder, and (c) the murder was motivated by race, caste, community, sex, place of birth, language, personal belief, or a similar ground.
For defence counsel: The identity-based motive requirement is a key defence point. Where a mob killing is motivated by personal enmity, property disputes, or other non-identity-based factors, Section 103(2) does not apply, and the prosecution must proceed under Section 103(1) with separate common intention or unlawful assembly charges. Defence counsel should also scrutinise whether each accused was genuinely "acting in concert" — mere presence at the scene may be insufficient.
For charge sheet drafting: When invoking Section 103(2), the charge sheet must specifically identify: the identity-based ground motivating the murder, the composition of the group (five or more persons), and evidence of acting in concert. Failure to establish the identity-based motive will result in the charge falling to Section 103(1), which has the same punishment but requires separate vicarious liability provisions.
For sentencing: The punishment under Section 103(2) — death or life imprisonment plus fine — is identical to Section 103(1). However, the legislative intent in creating a specific mob lynching provision signals that courts should treat identity-based mob murders as among the gravest categories, potentially meeting the "rarest of rare" threshold for the death penalty.
Does old case law still apply?
Since Section 103(2) BNS is a new provision, there is no directly applicable IPC precedent. However, the Supreme Court's observations on mob lynching and the general sentencing framework for murder provide interpretive guidance.
Tehseen S. Poonawalla v. Union of India (2018) 9 SCC 501 — The Supreme Court responded to rising mob lynching incidents by issuing comprehensive directions to state governments, including fast-track trials for mob violence cases, appointment of nodal officers in each district, and preventive measures. The Court described mob lynching as "horrendous acts of mobocracy" that "cannot be permitted to inundate the law of the land." This decision, while not a sentencing precedent for Section 103(2), establishes the judicial framework within which courts will interpret the new provision. The Court's observations on the gravity of identity-based mob violence will inform sentencing under Section 103(2).
Bachan Singh v. State of Punjab (1980) 2 SCC 684 — The "rarest of rare" doctrine for death penalty sentencing applies to Section 103(2) as it does to all murder provisions. Courts will need to develop criteria for when identity-based mob lynching meets this threshold. The systematic, group-coordinated nature of mob killings targeting victims based on immutable identity characteristics may weigh in favour of the death penalty in appropriate cases.
Judicial interpretation under BNS 103(2) (post-July 2024)
No post-July 2024 cases directly citing or applying Section 103(2) BNS were found in the Veritect Legal Intelligence database as of April 2026. This is consistent with the provision's novelty — since Section 103(2) is an entirely new offence with no IPC predecessor, cases registered under this provision would still be in the early stages of investigation or trial and are unlikely to have reached the High Court or Supreme Court level.
The closest analogous post-2024 jurisprudence involves cases under Section 302 IPC read with Section 149 IPC (unlawful assembly) for group murders, such as Haalesh v. State of Karnataka (Criminal Appeal No. 1954/2012, decided 2 February 2024), where the Supreme Court upheld convictions for murder by an unlawful assembly acting in concert. While this case was decided under the IPC framework, it reinforces the principle of collective criminal liability for group violence that underlies Section 103(2) BNS.
As courts begin applying Section 103(2) to post-July 2024 incidents, the key interpretive questions will be: (a) the evidentiary standard for proving "acting in concert," (b) how courts define "any other similar ground" beyond the enumerated identity categories, and (c) whether the provision triggers a presumption in favour of the death penalty given the legislative intent behind its creation.
Frequently asked questions
What is Section 103(2) BNS? Section 103(2) BNS is India's first specific mob lynching provision. It prescribes death or life imprisonment plus fine when a group of five or more persons acting in concert commits murder on grounds of race, caste, community, sex, place of birth, language, personal belief, or any other similar ground.
Was there an IPC equivalent for mob lynching? No. The IPC had no standalone mob lynching offence. Such cases were prosecuted under Section 302 (murder) read with Section 34 (common intention) or Section 149 (unlawful assembly). This required the prosecution to establish the general murder offence plus a separate vicarious liability provision.
Does Section 103(2) apply to all mob killings? No. Section 103(2) applies only when the murder is motivated by identity-based grounds — race, caste, community, sex, place of birth, language, personal belief, or similar grounds. A mob killing motivated by a personal dispute, property conflict, or other non-identity-based factor does not fall under this provision.
What is the punishment for mob lynching under BNS? Each member of a group of five or more persons acting in concert to commit identity-based murder faces death or imprisonment for life, plus fine, under Section 103(2) BNS. The Kerala High Court in State of Kerala v. Anu (2026) has held that the offence under Section 103(2) is treated as more serious than ordinary murder, reflecting the legislature's intent to specifically deter mob violence.
