Section 128 Evidence Act: Privilege Not Waived by Volunteering Evidence
A party does not automatically give up confidential lawyer-client communications merely by testifying in court. The rule, formerly in Section 128 of the Indian Evidence Act, 1872, is now reflected in Section 134 of the Bharatiya Sakshya Adhiniyam, 2023 (BSA).
Meaning of privilege and waiver
Legal professional privilege protects qualifying confidential communications between a client and legal adviser, the contents or condition of documents learned during professional employment, and advice given in that capacity, subject to statutory exceptions. Waiver means consent, express or legally inferred, allowing disclosure of otherwise protected material.
The principle of Section 128 is narrow: volunteering testimony does not itself amount to consent to disclosure of communications protected by the professional-communications provision. A different rule applies when a party calls the legal adviser as a witness and asks questions about protected matters.
Section 128 of the Indian Evidence Act, 1872 - statutory rule
If any party to a suit gives evidence therein at his own instance or otherwise, he shall not be deemed to have consented thereby to such disclosure as is mentioned in section 126; and, if any party to a suit or proceeding calls any such barrister, pleader, attorney or vakil as a witness, he shall be deemed to have consented to such disclosure only if he questions such barrister, attorney or vakil on matters which, but for such question, he would not be at liberty to disclose.
Historical editorial note: the reference to "pleader" in the earlier text was inserted by Act 18 of 1872, section 10. The quoted provision is reproduced for historical reference; the BSA governs its current application subject to savings.
Section 134 BSA, 2023 - corresponding provision
Section 134 of the Bharatiya Sakshya Adhiniyam is titled "Privilege not waived by volunteering evidence." It retains the central distinction between a party who gives evidence and a party who questions the party's legal adviser about matters ordinarily protected from disclosure. The current provision should be read together with Section 132 BSA (professional communications) and Section 133 BSA (application of that protection to interpreters and legal staff).
| Situation | Effect on privilege |
|---|---|
| A litigant gives evidence voluntarily. | That fact alone does not waive protected lawyer-client communications. |
| A party calls an advocate as a witness but asks only non-privileged questions. | Calling the advocate alone does not create a blanket waiver. |
| A party asks the advocate about a matter the advocate otherwise could not disclose. | Consent to disclosure may be inferred to the extent of the protected matter raised by those questions. |
| A communication furthers an illegal purpose or a relevant later crime or fraud is observed. | The statutory exceptions to professional privilege must be assessed separately. |
Practical illustrations
1. A client testifies about a property dispute
A party describes a property transaction in court. The party's testimony, by itself, does not authorise the opposing side to compel disclosure of all confidential advice received from the party's advocate.
2. A client questions the advocate about legal advice
A party calls the advocate and asks what confidential advice the advocate gave about the disputed transaction. By choosing to raise the protected subject through that witness, the party may be treated as consenting to the disclosure addressed by the question. This is not necessarily a waiver of every unrelated communication.
3. An advocate is called about an independently observed fact
Whether a question is privileged depends on what it seeks. The court must distinguish protected professional communications from facts that are independently provable or fall within an express statutory exception.
Important limits and exceptions
Section 128 does not create an absolute shield for all information possessed by a lawyer. The professional-communications rule excludes communications made in furtherance of an illegal purpose and certain facts observed in the course of employment indicating that a crime or fraud has occurred since the employment began. The protection can continue after the professional engagement ends, subject to those rules.
The precise scope of consent, the purpose of a question, and whether information was obtained in a professional capacity may require a court to examine the circumstances. Privilege is also distinct from the general rules governing relevance, admissibility and examination of witnesses.
Which evidence law applies after 1 July 2024?
The Indian Evidence Act, 1872 was repealed when the BSA commenced. Section 170 BSA contains savings for specified pending proceedings, so the applicable regime should be checked against the proceeding's commencement and status rather than assuming that every matter is governed identically.
