Section Number: 47
Section Title: Act Done by a Person Justified, or by Mistake of Fact Believing Himself Justified by Law
Act: Bharatiya Nyaya Sanhita, 2023 (BNS)
Status: Active
Applicability: Applicable throughout India.
BNS Section 47 is one of the General Exceptions under the Bharatiya Nyaya Sanhita, 2023. It recognizes that individuals may sometimes perform acts believing them to be legally justified due to a genuine mistake of fact.
The law distinguishes between:

Mistake of Fact

Mistake of Law
Protection is generally available for a bona fide mistake of fact but not for ignorance of law. This distinction is a fundamental principle of criminal jurisprudence.
Section Explanation
Simple Explanation (Plain English / Hinglish)
Agar koi vyakti kisi fact ko galat samajhkar honestly believe karta hai ki uska act kanoon ke hisab se justified hai, to usse criminal liability se protection mil sakti hai.
Example:
Ek police officer kisi vyakti ko arrest karta hai kyunki use reasonable belief hai ki warrant valid hai. Baad mein pata chalta hai ki warrant mein factual error tha.
Agar officer ne honestly aur good faith mein kaam kiya tha, to Section 47 uski protection kar sakta hai.
Important baat:
-
Mistake of Fact protected ho sakti hai.
-
Mistake of Law protected nahi hoti.
Legal Definition (Original Law Text)
BNS Section 47 substantially provides that nothing is an offence which is done by any person who is justified by law, or who by reason of a mistake of fact and not by reason of a mistake of law, in good faith believes himself to be justified by law in doing it.
Practical Interpretation
Courts generally verify:
-
Whether a mistake existed.
-
Whether the mistake related to facts and not law.
-
Whether the belief was genuine.
-
Whether the act was performed in good faith.
-
Whether the person reasonably believed the act was legally justified.
If these requirements are satisfied, criminal liability may not arise.

Bailable / Non-bailable: Not applicable.

Real-Life Examples
Example 1: Police Officer Arresting the Wrong Person
A police officer receives reliable information that a particular individual is the subject of a valid arrest warrant. Acting in good faith, the officer arrests the person. Later, it is discovered that there was a factual identification error.
Since the officer acted under a genuine mistake of fact, Section 47 may provide protection.
Example 2: Citizen Assisting Police
A citizen helps police officers detain an individual whom he honestly believes to be a wanted criminal. Later, the suspect is found innocent.
If the citizen acted reasonably and in good faith, protection may be available.
Example 3: Recovery of Property
A person retrieves a bag believing it belongs to him because it closely resembles his own property. Upon opening it, he discovers it belongs to another individual.
If the mistake was genuine and based on facts, criminal intention may be absent.

Legal Insights
When is this Section Applied?
Section 47 commonly applies in situations involving:
-
Wrongful arrests based on mistaken identity.
-
Mistaken ownership disputes.
-
Execution of official duties.
-
Citizen assistance to authorities.
-
Good faith reliance on factual information.

Common Misuse Scenarios
Claiming Ignorance of Law
Many accused persons argue that they did not know the law.
This is generally not protected because Section 47 applies to mistakes of fact, not mistakes of law.
Fabricated Mistake
An accused may falsely claim a factual misunderstanding after committing an offence.
Courts carefully evaluate evidence before accepting such claims.
Unreasonable Beliefs
Protection may not apply where the alleged mistake was clearly unreasonable.
Defenses Available
Common defenses include:
-
Good faith.
-
Honest belief.
-
Mistake of fact.
-
Lack of criminal intention.
-
Reasonable conduct.
-
Legal justification.
Courts examine whether a prudent person could have made a similar mistake under the circumstances.
Difference Between Mistake of Fact and Mistake of Law
This distinction is crucial.
Mistake of Fact
Example:
A person takes another person's umbrella believing it is his own.
Protection may apply.
Mistake of Law
Example:
A person knows the umbrella belongs to someone else but believes taking it is legally permitted.
Protection generally does not apply.
The law presumes that everyone knows the law, but it recognizes that mistakes about facts can occur honestly.
Importance of Good Faith
Good faith is one of the most important requirements under Section 47.
Courts consider:
-
Honest belief.
-
Reasonable inquiry.
-
Absence of malice.
-
Conduct before and after the incident.
-
Available information at the time.
A person cannot deliberately ignore obvious facts and later claim good faith.
Importance of BNS Section 47
Section 47 reflects a fundamental principle of criminal law:
"An act done honestly under a genuine mistake of fact should not automatically attract criminal liability."
The provision ensures fairness by protecting individuals who act reasonably and without criminal intent.
Without such protection:
-
Honest mistakes could lead to criminal prosecution.
-
Public officials might hesitate to perform duties.
-
Citizens could fear assisting law enforcement.
Modern Relevance
In modern society, decisions are often made quickly based on available information.
Examples include:
-
Digital identity verification.
-
Online transactions.
-
Law enforcement operations.
-
Security checks.
-
Property disputes.
Mistakes of fact can occur despite reasonable care. Section 47 provides a framework for evaluating such situations fairly.
Conclusion
BNS Section 47 is an important legal safeguard protecting individuals who act under lawful authority or under a genuine mistake of fact while believing themselves justified by law. The section recognizes that criminal liability should generally be based on wrongful intention and not honest factual misunderstandings. By distinguishing between mistakes of fact and mistakes of law, the provision promotes fairness, justice, and reasonable accountability within India's criminal justice system.
