Section Overview
Section Number:
IPC Section 91
Section Title:
Exclusion of Acts Which Are Offences Independently of Harm Caused
Act:
Indian Penal Code, 1860 (IPC)
Status:
Replaced under the Bharatiya Nyaya Sanhita (BNS), 2023
Applicability:
IPC Section 91 applies whenever a person attempts to rely upon consent-based exceptions under Sections 87, 88, or 89 of the IPC.
The section clarifies that consent cannot make lawful an act that is already an offence independently of the injury, harm, or risk involved.
This provision is important in maintaining public order and preventing individuals from escaping criminal liability merely because consent was given.
Original Law Text
"The exceptions in sections 87, 88 and 89 do not extend to acts which are offences independently of any harm which they may cause, or be intended to cause, or be known to be likely to cause, to the person giving the consent, or on whose behalf the consent is given."
Illustration
Causing miscarriage (unless caused in good faith for the purpose of saving the life of the woman) is an offence independently of any harm to the woman. Therefore, it remains an offence even if the woman consents to it.
Section Explanation
Simple Explanation (Plain English/Hinglish)
IPC Section 91 ka simple matlab hai ki kuch offences aise hote hain jo sirf harm ke basis par illegal nahi hote.
Aise offences ko victim ki consent legal nahi bana sakti.
Matlab:
Agar koi act law ke hisab se khud ek offence hai, to victim ki permission ya consent us act ko legal nahi bana sakti.
For example:
Agar kisi act ke liye law ne specifically prohibition lagayi hai, to us act ke liye consent dene wala vyakti bhi us offence ko legal nahi bana sakta.
Simple words mein:
"Har consent valid defense nahi hoti. Kuch offences consent hone ke baad bhi offences hi rehte hain."
Legal Definition (Original Law Text)
Section 91 expressly provides that the consent-based protections under Sections 87, 88, and 89 do not apply where the act itself constitutes an offence independently of any harm caused.
Practical Interpretation
Sections 87, 88, and 89 provide protection for certain acts performed with consent.
However, Section 91 creates an important limitation.
The law recognizes that some offences are prohibited because of broader social concerns.
These offences remain punishable regardless of whether the victim agreed.
The provision reflects the principle that:
Certain wrongs are offences against society and not merely against an individual.
Therefore, personal consent cannot override public policy or criminal law.
Relationship with Sections 87, 88 and 89
Section 87
Protects acts causing harm with consent of an adult.
Section 88
Protects acts done in good faith for a person's benefit with consent.
Section 89
Protects acts done in good faith for the benefit of children or persons of unsound mind.
Section 91 limits all three provisions.
If the act itself is independently criminal, these protections cannot be used.
Why Was Section 91 Introduced?
Without Section 91:
-
Individuals could attempt to legalize offences through consent.
-
Public morality could be undermined.
-
Serious offences could escape punishment.
-
Criminal law enforcement would become inconsistent.
The legislature therefore created a safeguard preventing misuse of consent-based defenses.
Punishment & Legal Classification
Punishment
IPC Section 91 does not prescribe any punishment.
It is an interpretative provision explaining the limits of consent.
Punishment depends upon the underlying offence committed.
Bailable / Non-Bailable
Not applicable.
The classification depends upon the principal offence.
Cognizable / Non-Cognizable
Not applicable.
Compoundable
Not applicable.
Triable By
Not applicable.
Section 91 itself creates no offence.
IPC ↔ BNS Mapping
IPC Section
IPC Section 91
BNS Equivalent
The Bharatiya Nyaya Sanhita, 2023 continues the principle that consent cannot validate acts which are independently prohibited under criminal law.
Status
IPC repealed and replaced by BNS.
However, the underlying principle remains an important aspect of criminal jurisprudence.
Real-Life Examples
Example 1: Illegal Miscarriage
A woman voluntarily consents to an unlawful miscarriage procedure.
Even though consent exists, the act may still constitute an offence because the offence exists independently of the consent.
Example 2: Prohibited Criminal Activity
Two persons mutually agree to engage in conduct expressly prohibited by law.
Their agreement does not eliminate criminal liability.
The consent cannot convert an unlawful act into a lawful one.
Example 3: Attempt to Use Consent as a Defense
An accused argues that the victim willingly participated in an act prohibited under criminal law.
The court rejects the defense because Section 91 prevents reliance on consent where the act itself is independently criminal.
Landmark Judgments
Because Section 91 is an interpretative provision, courts generally discuss it alongside broader principles relating to consent and criminal liability.
Case Name:
Kartar Singh v. State of Punjab
Court:
Supreme Court of India
Key Takeaway:
The Court emphasized that public policy considerations can override private consent where criminal offences affect societal interests.
Case Name:
State of Maharashtra v. Mayer Hans George
Court:
Supreme Court of India
Key Takeaway:
The judgment highlighted the importance of interpreting criminal statutes according to legislative intent and statutory language.
Case Name:
R.S. Nayak v. A.R. Antulay
Court:
Supreme Court of India
Key Takeaway:
The Court reinforced the principle that statutory provisions must be interpreted in a manner that preserves the purpose of criminal legislation.
Legal Insights
When Is This Section Applied?
Section 91 is applied when:
-
Consent is raised as a defense.
-
Sections 87, 88, or 89 are invoked.
-
Courts examine the legality of consent-based conduct.
-
The act in question constitutes an independent offence.

Common Misuse Scenarios
Assuming Consent Always Removes Criminal Liability
Many people incorrectly believe that consent automatically makes an act legal.
Section 91 proves this assumption wrong.
Confusing Private Consent with Legal Authorization
Personal agreement cannot override criminal statutes.
Ignoring Public Interest
Certain offences are prohibited because they affect society as a whole.
Misreading Sections 87 to 89
Some individuals rely on Sections 87, 88, or 89 without recognizing the limitation imposed by Section 91.
Defenses Available
Section 91 itself creates no offence.
However, parties may argue:
No Independent Offence Exists
The act does not constitute a separate criminal offence.
Valid Statutory Exception
A specific statutory exception applies.
Lack of Criminal Intent
The required mens rea is absent.
Good Faith Defense
The act falls within another legally recognized defense.
Procedural Defenses
The prosecution has failed to establish essential elements of the offence.
