Section 125 Evidence Act: Protection of Information About Commission of Offences

The law protects the identity of certain sources who provide information about offences to Magistrates, police officers and revenue officers. The former Section 125 of the Indian Evidence Act, 1872 is now addressed by Section 131 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA).

Current law: The Bharatiya Sakshya Adhiniyam, 2023 came into force on 1 July 2024. Section 131 is the corresponding provision for protection of information concerning offences. The earlier Evidence Act may remain relevant to proceedings saved under the BSA's repeal and savings provision, Section 170.

What did Section 125 of the Indian Evidence Act, 1872 provide?

No Magistrate or police-officer shall be compelled to say whence he got any information as to the commission of any offence, and no revenue officer shall be compelled to say whence he got any information as to the commission of any offence against the public revenue.

Explanation: Revenue-officer in this section means any officer employed in or about the business of any branch of the public revenue.

The provision was substituted by Act 3 of 1887, section 1. Its purpose was to protect the source of crime-related information and encourage reporting without fear that an officer would be forced to identify the informant during testimony.

Section 131 of the Bharatiya Sakshya Adhiniyam, 2023

Section 131, titled Information as to commission of offences, carries forward the rule that Magistrates and police officers cannot be compelled to disclose the source of information concerning an offence. It also protects revenue officers against compelled disclosure of the source of information concerning offences against public revenue.

The explanation concerning a revenue officer covers an officer employed in or about the business of any branch of public revenue. Consult the Bharatiya Sakshya Adhiniyam, 2023 on India Code for the enacted text and subsequent updates.

Meaning and scope of the protection

1. Magistrates and police officers

A Magistrate or police officer cannot be compelled to reveal from whom information about an offence was received. The protection concerns the origin of the information, not a general exemption from giving evidence about every fact in the investigation.

2. Revenue officers

A revenue officer receives comparable protection for the source of information about an offence against public revenue. The statutory distinction matters: the revenue-officer limb is tied to revenue-related offences.

3. Protection against compelled disclosure

The provision restricts compelled identification of the source in legal proceedings. It does not automatically make the underlying allegations true, establish the guilt of an accused person, or remove the prosecution's obligation to prove its case using admissible evidence.

Practical illustrations

  • Police tip-off: A police officer receives confidential information about an alleged theft. The officer ordinarily cannot be compelled under this provision to identify the informant merely because the officer is called as a witness.
  • Revenue information: A revenue officer receives a tip concerning an alleged offence against public revenue. The statutory protection applies to compelled disclosure of the information source.
  • Independent evidence: Documents, seized materials and witnesses relied on to prove the alleged offence must still satisfy the applicable rules of evidence and fair-trial requirements. Source protection is not a substitute for proof.

Limits and related legal principles

Section 131 addresses the compelled disclosure of an information source. It should be distinguished from the protection for official communications under the former Section 124, and from privilege concerning affairs of State under the former Section 123. Those provisions protect different interests and have distinct requirements.

Questions about access to investigative records, witness disclosure, an accused person's defence rights, and evidentiary fairness must be assessed under the applicable procedural law and constitutional principles. This article does not suggest that the privilege overrides every other legal requirement in every situation.

Does the old Evidence Act still apply?

The Indian Evidence Act, 1872 was repealed by the BSA. However, Section 170 of the BSA includes a savings provision for specified proceedings pending immediately before commencement. The governing statute depends on the proceeding and its procedural posture, so check the relevant commencement and savings rules before citing the old or new section.
