The Supreme Court of India, in Suo Motu Writ Petition (Criminal) No. 2 of 2025, delivered a landmark judgment that reshapes attorney–client privilege in India. The ruling strengthens constitutional protections for external advocates, restricts the investigative powers of the police, and controversially excludes in-house counsel from full privilege coverage.
The matter originated from a loan dispute FIR in Ahmedabad, where investigators issued a notice under Section 179 of the BNSS, 2023 compelling the client’s Advocate to appear and disclose case-related facts. The Advocate challenged this action as violating fundamental rights under Articles 19(1)(g), 21, 20(3), and 22(1). After the High Court dismissed the plea, the Supreme Court took up the issue suo motu due to its constitutional significance.
The Court examined whether police can summon lawyers directly, whether judicial oversight is required when a lawyer is suspected of misconduct, whether Section 132 of the BSA, 2023 extends privilege to in-house counsel, and whether a lawyer’s documents and digital devices enjoy legal protection. It reaffirmed that attorney–client privilege is grounded in constitutional guarantees of meaningful legal representation and statutory protection under Section 132, which prohibits disclosure of client communications or advice except where the communication furthers an illegal act or reveals crime or fraud committed after the lawyer’s engagement.
The Court held that investigating agencies cannot routinely summon advocates and must independently collect evidence, and if invoking an exception under Section 132, the summons must specify the reason and carry written approval from a Superintendent of Police or higher. It also clarified that lawyers may challenge improper summons before courts under Section 528 BNSS. The most controversial holding was that in-house counsel, being employees and not independent practitioners enrolled with State Bar Councils, do not receive full privilege under Section 132. Their protection applies only indirectly for communications involving external lawyers. The Court relied on the principle that independence is essential to privilege, echoing European jurisprudence such as the Akzo Nobel ruling. Additionally, the Court offered limited protection for documents and digital devices, stating that investigators cannot directly seize a lawyer’s devices and that any examination must occur under judicial supervision, ensuring other clients’ confidential data remains protected.
This distinction between external and in-house lawyers has raised significant concerns. Privilege protects the client, not the lawyer, and denying corporations the same protection for choosing in-house counsel may conflict with Article 14. In-house teams often manage the most sensitive legal and compliance matters, making them vulnerable to investigative pressure. The ruling effectively forces clients to choose between organisational efficiency and constitutional protection, weakening the internal legal ecosystem within companies.
For businesses, the judgment means routing sensitive matters through external counsel and revising internal communication and digital data policies. In-house counsel must reassess documentation practices, separate legal advice from business communication, and involve external lawyers in high-stakes matters. Investigators, meanwhile, must adhere to stricter protocols when seeking information from lawyers.
Ultimately, the judgment strengthens privilege for external advocates and curbs investigative overreach but leaves unresolved concerns about the exclusion of in-house counsel, an issue that may require legislative reconsideration. It reinforces the principle that lawyers cannot be treated as investigative extensions and that the confidentiality of legal representation is integral to constitutional freedoms.
