Client–Advocate Privilege Shields the “Source” of Defence Documents: Revisional Courts Cannot Compel Advocates’ Disclosure Absent Prima Facie Fraud
1. Introduction
In MCDONALDS INDIA LTD v. STATE OF NCT OF DELHI & ANR (Delhi High Court, 12-01-2026; 2026 DHC 228),
the petitioner company invoked Articles 226/227 of the Constitution read with Section 482 Cr.P.C. to challenge directions issued
by the revisional court (Ld. ASJ) requiring the petitioner’s advocates to file personal affidavits disclosing the
“source” of certain documents placed on the record in a criminal revision.
The dispute arose from a private criminal complaint by respondent no. 2 (Deepak Khosla) against the petitioner and others
alleging multiple IPC offences and seeking search and seizure orders under Sections 91 and 94 Cr.P.C. After the ACMM allowed the
request for search/seizure, the petitioner filed a criminal revision. During the revision, the petitioner relied upon copies of
two applications previously filed by the complainant in 2011 (in another forum) to contend that there was no urgency justifying
intrusive search directions; an ex parte stay followed.
Respondent no. 2 then moved an application under Section 340 Cr.P.C., alleging that the 2011 applications were not part of the
trial court record at the relevant time and were “surreptitiously” introduced—implying illegal procurement/leakage and
consequent fraud/perjury. The revisional court directed the advocates to disclose, via affidavit, when the typed copies were
filed and the “source” of their contents, and later issued notice for non-compliance. The High Court was thus asked to decide:
Can a revisional court compel advocates to personally disclose the source of documents filed on behalf of a client?
2. Summary of the Judgment
The Delhi High Court (Neena Bansal Krishna, J.) quashed:
(i) the revisional court’s order dated 20.05.2017 insofar as it directed the petitioner’s advocates to file personal affidavits
disclosing the “source” of the documents, and
(ii) all consequential proceedings, including the order dated 22.07.2017 issuing notice to counsel for contempt/non-compliance.
The Court held that compelling an advocate to disclose the “source” of documents handed over by a client for purposes of defence
falls squarely within the protection of Section 126 of the Indian Evidence Act, 1872 (client–advocate privilege).
The fraud/illegal purpose exception in the proviso to Section 126 could not be invoked absent prima facie material showing that
the privileged communication itself was in furtherance of an illegal purpose or that facts observed by counsel demonstrated
crime/fraud since engagement. On the facts, a plausible explanation existed: the petitioner claimed the documents had been served
upon it in 2013 in Company Law Board proceedings, undermining the “theft/leak” narrative at the threshold.
3. Analysis
3.1 Precedents Cited
(a) Three Rivers DC v. Bank of England
The judgment relied on the rationale (as noticed in Three Rivers DC v. Bank of England and accepted by Indian courts)
that legal advice requires a protected zone of confidentiality: a person must be able to consult a lawyer candidly, and that
confidence must be “inviolable” to serve the administration of justice. The High Court used this rationale to emphasize that
privilege is not a mere professional courtesy to counsel but a structural safeguard of adjudication—one that should not be diluted
through routine demands for lawyers to “explain sources” of defence materials.
Cited for the proposition that where the contents of a document are privileged, no action can be taken against counsel for
refusing disclosure. This supported two linked conclusions:
-
A lawyer’s refusal to reveal privileged information cannot itself become the basis for punitive or coercive court action.
-
Contempt-style pressure (or notices framed as non-compliance) is particularly inappropriate where the demand collides with a
statutory bar under Section 126.
(c) Donald Weston v. Pearey Mohan Dass, 13 IND CAS 335
Respondent no. 2 relied on Donald Weston v. Pearey Mohan Dass, 13 IND CAS 335 to argue that there is “no privilege
against the Court” and that advocates, as officers of the court, can be asked to disclose whether a charge is made on
instructions and the source of such instructions to preserve the purity of proceedings.
The High Court treated this as an overbroad application: while courts have strong supervisory powers to protect their process,
they cannot compel disclosure that the law expressly protects unless the case is brought within the recognized
statutory exception (here, the proviso to Section 126). In effect, the Court read “duty to the court” as coexisting with—not
overriding—legislated privilege, except where the privilege is pierced under the proviso on a proper prima facie foundation.
3.2 Legal Reasoning
(a) Scope of Section 126 IEA: “Source” as protected communication
The Court treated the identity/origin of a document supplied by a client for conducting litigation as part of the protected
professional communication. The reasoning is practical and doctrinal:
-
Section 126 bars disclosure of any communication made to counsel “in the course and for the purpose of” employment, and also
bars stating “the contents or condition of any document” counsel became acquainted with during such employment.
-
The act “Client X gave me this document” (or any equivalent explanation of “source”) is not a neutral procedural fact; it is
information derived directly from the client relationship and litigation strategy.
-
Responsibility for filing and owning the factual case rests primarily with the party/client. Forcing counsel to
become a witness about provenance shifts that burden in a way that undermines the adversarial system and the client’s right to
confidential legal representation.
(b) Proviso to Section 126: exception requires prima facie foundation
The Court accepted that privilege is not absolute: the proviso excludes protection for (i) communications in furtherance of an
illegal purpose, and (ii) facts observed by counsel showing crime/fraud since commencement of employment. However, it insisted on
a threshold test:
-
Allegations of illegality are not enough; there must be prima facie material to bring the case within the
proviso before compelling disclosure.
-
On the record, the documents were used to argue lack of urgency for search/seizure—an orthodox litigation purpose.
-
The petitioner’s explanation (service of the documents in 2013 during Company Law Board proceedings) provided a plausible lawful
route of possession, weakening the allegation of theft/leakage at the preliminary stage.
Consequently, the revisional court’s approach—first compel counsel to disclose “source” and then decide whether privilege applies—was
treated as backwards. Privilege is the default; the exception must be shown before compulsion.
(c) “No privilege against the Court” vs. statutory privilege
The High Court drew a clear boundary between (i) the court’s power to ensure truthful proceedings and (ii) the court’s power to
compel privileged disclosures. The judgment underscores that:
-
Courts can inquire into offences affecting administration of justice (including via Section 340 Cr.P.C.), but inquiries must
remain within “judicial contours”.
-
Counsel’s status as “officer of the court” does not erase Section 126. Ethical duty to the court cannot be converted into a
general duty to disclose client-sourced information.
(d) Effect on consequential coercive steps
Because the foundational direction was illegal, the High Court quashed not only the affidavit direction but also the consequential
notice issued to counsel for contempt/non-compliance. This confirms that when disclosure orders violate privilege, enforcement
mechanisms built on them also fail.
3.3 Impact
-
Strengthening litigation confidentiality: The judgment clarifies that “source/provenance” of defence documents
provided by a client is ordinarily privileged, limiting fishing inquiries against counsel.
-
Higher threshold for piercing privilege: Courts must identify prima facie material that squarely attracts the
proviso to Section 126 before ordering disclosure from an advocate.
-
Protection against counsel-targeting tactics: The ruling indirectly addresses strategic attempts to shift the
dispute onto opposing lawyers, which can chill representation and distort proceedings.
-
Guidance for Section 340 Cr.P.C. practice: Even where “administration of justice” concerns are invoked, the
inquiry cannot begin by compelling privileged disclosures from counsel; parties must be called upon to explain their case, and
privilege must be respected unless the exception is first established.
4. Complex Concepts Simplified
4.1 Section 126 (Indian Evidence Act) — client–advocate privilege
This rule means a lawyer generally cannot reveal what the client told them, what documents the client provided, or what advice the
lawyer gave—unless the client expressly consents. The privilege exists to ensure clients can speak freely with counsel without
fear that counsel will be forced to disclose those communications later.
4.2 Proviso to Section 126 — the “crime-fraud” exception
Privilege does not protect communications that are themselves meant to help commit an illegal act, nor does it protect facts the
lawyer observes during employment that show a crime or fraud occurred after the lawyer was engaged. Importantly, a court should
not apply this exception merely because someone alleges wrongdoing; there must be some prima facie basis.
4.3 Section 340 Cr.P.C. — proceedings for offences affecting justice
Section 340 is a mechanism allowing courts to consider action (typically prosecution) for certain offences like perjury that impact
the administration of justice. It is not meant to become a shortcut to compel privileged disclosures from advocates.
4.4 Revisional court
A revisional court reviews the correctness/legality of certain lower-court orders. Even when supervising the process, it must act
within statutory limits—especially where evidence law imposes clear bars on compelled disclosure.
5. Conclusion
The Delhi High Court’s core contribution is a clear operational rule: courts cannot compel advocates to file personal
affidavits disclosing the “source” of documents filed on behalf of a client, because such disclosure is ordinarily protected by
Section 126 IEA; the crime/fraud exception cannot be invoked without prima facie material. By quashing both the affidavit
direction and the consequential coercive notice, the Court reinforced that preservation of judicial integrity must proceed through
lawful methods that do not erode the statutory foundations of client–advocate confidentiality.
