BNS General Principles: Exceptions, Private Defence and Group Liability — Judicial Services
Weightage: Since 1 July 2024 the Bharatiya Nyaya Sanhita, 2023 (BNS) has replaced the Indian Penal Code, 1860 for offences committed on or after that date, and proceedings for earlier offences continue under the old Code. Judicial exams now ask the BNS section with the IPC section beside it. Section numbers below follow the commonly published conversion tables; confirm each against the Bare Act before you quote it.
1. The shape of the new Code
The BNS has 358 sections against the IPC's 511. Its structure, in outline:
| BNS chapters | Subject | Old IPC |
|---|---|---|
| I to II | Preliminary, punishments | 1 to 75 |
| III | General exceptions (ss. 14 to 44) | 76 to 106 |
| IV | Abetment, conspiracy and attempt | 107 to 120B, 511 |
| V to onwards | Offences against women and children, the body, property, State | rest |
A useful rule: for general exceptions, the BNS section is the IPC section minus 62 (IPC 76 became BNS 14, IPC 96 became BNS 34, IPC 100 became BNS 38).
2. Actus reus, mens rea and strict liability
A crime has a guilty act (actus reus) and, ordinarily, a guilty mind (mens rea). Statutory offences may create strict liability where the legislature so intends (State of Maharashtra v. M. H. George, 1965), so the exam asks whether intention is required for the particular offence.
The stages of a crime are intention, preparation, attempt and commission. Intention and preparation are generally not punishable. Attempt is punishable (BNS 62, IPC 511), and a separate attempt provision exists for murder (BNS 109) and culpable homicide (BNS 110).
3. Punishments and community service
BNS Section 4 lists the punishments: death, imprisonment for life, imprisonment (simple or rigorous), forfeiture of property, fine and community service. Community service is new, for specified petty offences such as petty theft, defamation and some attempts to commit suicide to compel a public servant and similar minor acts. The Code also provides for commutation (BNS 5).
Territorial reach: the Code applies to offences within India and, under Section 1(4) and (5), to offences committed by Indian citizens abroad and to offences committed on Indian ships and aircraft.
4. General exceptions: the structure
The Code lists situations where an act is not an offence. They fall in groups:
- Mistake of fact (BNS 17, IPC 79) and judicial acts (15, 16).
- Accident (BNS 18, IPC 80), necessity (19, IPC 81).
- Infancy: a child under seven has complete immunity (BNS 20, IPC 82), and a child between seven and twelve of immature understanding is also protected (BNS 21, IPC 83).
- Unsound mind (BNS 22, IPC 84): the person must, at the time of the act, be incapable of knowing the nature of the act or that it is wrong or contrary to law. The test follows the M'Naghten rule, and legal insanity differs from medical insanity.
- Intoxication (BNS 23, IPC 85 and 86): involuntary intoxication is a defence, and voluntary intoxication is not, though it may negate a specific intent.
- Consent and good faith (BNS 25 to 33).
5. Private defence
BNS 34 to 44 (IPC 96 to 106). A person may defend his own body and the body of another (BNS 35) and property, against specified offences, using no more force than necessary.
- BNS 37 (IPC 99): no right against a public servant acting in good faith, or where there is time to seek the protection of public authorities, and the right never extends to more harm than necessary.
- BNS 38 (IPC 100): the right of body extends to causing death if the assault gives rise to a reasonable apprehension of death, grievous hurt, rape, kidnapping, acid attack and similar, as listed.
- BNS 41 and 44 (IPC 103 and 106): the right of property extends to causing death for robbery, house-breaking by night, mischief by fire and similar. A person is also protected where a risk of harm to an innocent arises while defending against a deadly assault (BNS 44).
The Supreme Court's principles (Darshan Singh v. State of Punjab, 2010) hold that the right is preventive, not punitive, begins as soon as reasonable apprehension arises, and is judged without hindsight in the heat of the moment, though the accused should show it on a balance of probabilities.
6. Attempt, abetment and conspiracy
- Attempt (BNS 62): acts beyond preparation towards the commission of an offence punishable with imprisonment. Punishment is up to half the longest term or the fine prescribed.
- Abetment (BNS 45, IPC 107): by instigation, conspiracy or intentional aid. BNS 46 defines it, and the abettor is punished even if the act is not committed (BNS 49 and 50 distinguish the cases).
- Criminal conspiracy (BNS 61, IPC 120A and 120B): an agreement between two or more persons to do an illegal act or a legal act by illegal means. For serious offences, the agreement is itself the offence, and for others an overt act is required.
7. Group liability: common intention and common object
Common intention (BNS 3(5), IPC 34): when a criminal act is done by several persons in furtherance of the common intention of all, each is liable as if he alone did it.
- It needs a prior meeting of minds, though it can be formed on the spot (Pandurang v. State of Hyderabad, 1955).
- Participation in the act is required, as in Barendra Kumar Ghosh (1925), "they also serve who only stand and wait".
- It is a rule of evidence, not a substantive offence.
Common object (BNS 190, IPC 149): where an unlawful assembly (BNS 189, IPC 141) of five or more persons commits an offence in prosecution of the common object, every member is liable. The difference from common intention:
| Feature | Common intention | Common object |
|---|---|---|
| Section | BNS 3(5) | BNS 190 |
| Minimum persons | Two | Five |
| Basis | Prior meeting of minds | Membership of assembly |
| Participation | Required | Not required |
8. A problem-answer pattern
A, B and C go to settle a land dispute with X. A has a gun, and B and C carry sticks. A shoots X dead while B and C hold X's brother back. Answer in four steps:
- The issue is common intention under BNS 3(5): was there a plan to kill, or only to threaten?
- If a plan to kill is inferred from conduct, each is liable for murder.
- If the plan was only to beat, B and C may be liable for hurt and A alone for murder, because the shooting exceeded the common intention.
- A prior meeting of minds can be shown from conduct, such as arming and acting together.
Common traps judicial exams set here
- Quoting an IPC section for an offence after 1 July 2024. Cite the BNS, with the old section as a reference.
- Treating community service as a general punishment. It is for stated petty offences.
- Saying private defence allows retaliation. It is preventive and proportionate.
- Confusing common intention and common object. One needs two persons and a plan, the other five and an unlawful assembly.
- Applying the 62 rule outside Chapter III. It works only for general exceptions.
Memory aids
- "BNS minus IPC is 62": general exceptions.
- "3(5) intention, 190 object": group liability.
- "Prior meeting of minds": the test for common intention.
Summary
The BNS reorganises 511 IPC sections into 358 and adds community service as a punishment. General exceptions in BNS 14 to 44 cover infancy, unsound mind, intoxication and private defence.
Attempt, abetment and conspiracy are the inchoate offences, and group liability rests on common intention in BNS 3(5) and common object in BNS 190.
Exam protocol
- Cite the BNS section first and the IPC section after.
- Test each exception on the facts and the burden of proof.
- State whether liability is individual, common intention or common object.
