Legal professional privilege: India vs US attorney-client vs UK/EU - the in-house counsel gap

Picture one email: the general counsel of a multinational writes to the CEO analysing the legal risk of a proposed practice. In New York, that email is privileged. In London, probably - if the CEO was within the authorised "client" group. In Brussels, if the European Commission raids the office in a competition investigation, it is not protected at all. And in India, after the Supreme Court's October 2025 ruling, the GC's own status as a salaried employee places the email outside advocate-client privilege - unless external counsel was in the loop. This is the in-house counsel privilege gap: the same document, four legal fates. This analysis maps the four regimes for the professionals who live inside them - it is legal information, not legal advice, and privilege questions in live matters belong with counsel in the relevant jurisdiction.

The same email, four outcomes

Privilege doctrines answer three design questions differently across jurisdictions: whose communications are protected (any lawyer, or only independent ones?), which communications (legal advice only, or litigation materials too?), and against whom (courts, regulators, police?). The in-house lawyer sits at the fault line of the first question. Jurisdictions that anchor privilege in the client's right to candid advice (the US) extend it to employed lawyers; jurisdictions that anchor it in the lawyer's independence from the client (the EU, and now India for investigative purposes) do not. The UK sits between, protecting the employed lawyer but narrowing the "client". Multinational teams cannot change the doctrines; they can only route their communications with the map in view.

India: the 2025 ruling that redrew the line

India's privilege rules moved statutes in 2024 and doctrine in 2025. The Indian Evidence Act's professional-communications provisions (ss.126-129) were re-enacted on 1 July 2024 as ss.132-134 of the Bharatiya Sakshya Adhiniyam, 2023: s.132 bars an advocate from disclosing client communications without express consent (with the familiar exceptions for communications in furtherance of an illegal purpose and facts showing crime or fraud in progress), extends the bar to advocates' clerks and employees via s.132(3), and s.134 separately protects anyone from being compelled to disclose confidential communications with their "legal adviser" unless they offer themselves as a witness.

The doctrinal move came in In Re: Summoning Advocates who give legal opinion or represent parties during investigation of cases, 2025 INSC 1275 (31 October 2025). A three-judge bench headed by the Chief Justice held, first, that investigating officers cannot summon a party's advocate to learn case details unless a s.132 exception genuinely applies - any such summons needs recorded facts, prior written approval of an officer not below Superintendent of Police, and is judicially reviewable. But the bench also held, squarely, that in-house counsel are not "advocates" for s.132 purposes - full-time salaried employment is incompatible with practising as an advocate under Bar Council of India Rule 49 (the rule enforced in Satish Kumar Sharma v Bar Council of Himachal Pradesh, (2001) 2 SCC 365) - leaving employed lawyers only the narrower s.134 shield. The older, more generous Bombay High Court line (Municipal Corporation of Greater Bombay v Vijay Metal Works, AIR 1982 Bom 6, which had extended ss.126/129 protection to salaried legal advisers) now reads as history rather than the governing rule. What survives untouched: communications with external advocates remain fully privileged - which is why routing has become the operative Indian strategy.

United States: the Upjohn standard

The US takes the opposite view of employment. In Upjohn Co v United States, 449 U.S. 383 (1981), the Supreme Court unanimously rejected the "control group" test and held that attorney-client privilege covers communications between corporate counsel and employees at any level, where made at the direction of superiors so counsel can give the corporation legal advice. The privilege belongs to the corporation, survives investigations, and draws no distinction between employed and external lawyers. The boundary that matters instead is purpose: only communications for legal advice are protected - the GC's business-strategy commentary is not - and mixed-purpose communications generate exactly the litigation US courts spend their privilege docket on.

Alongside sits the work-product doctrine - born in Hickman v Taylor, 329 U.S. 495 (1947), codified in Federal Rule of Civil Procedure 26(b)(3) - protecting materials prepared in anticipation of litigation, with near-absolute protection for counsel's mental impressions and opinions. For in-house teams the practical US framework is therefore two-layered: label and segregate legal advice (privilege), and mark litigation-driven analysis as prepared in anticipation (work product). Our companion piece on privilege and AI tools covers how those doctrines interact with technology vendors and confidentiality duties.

United Kingdom: two privileges, one narrow client

English law splits legal professional privilege in two. Legal advice privilege covers lawyer-client communications for giving or receiving legal advice; litigation privilege covers communications and documents whose dominant purpose is litigation reasonably in contemplation, including with third parties. In-house lawyers hold both: since Alfred Crompton Amusement Machines v Customs and Excise [1972] 2 QB 102, salaried legal advisers are "in every respect in the same position" as external counsel - for their work as legal advisers, not their executive roles.

The UK's trap is not the lawyer but the "client". Three Rivers (No 5) [2003] EWCA Civ 474 confined legal advice privilege to communications with the narrow group of employees actually authorised to seek and receive the advice - so an employee's factual briefing to the company's own lawyers, outside that group, is not covered. The Court of Appeal in SFO v ENRC [2018] EWCA Civ 2006 called that rule out of step with international common law and a systematic disadvantage to large corporations - while holding that only the Supreme Court can overturn it. ENRC did restore litigation privilege's practical force for internal investigations (interview notes prepared when criminal proceedings were reasonably in contemplation were protected), which is why UK investigation protocols now document contemplation-of-proceedings early and constitute the client group deliberately.

European Union: the Akzo exclusion

At EU level the exclusion is categorical. Akzo Nobel Chemicals v Commission (Case C-550/07 P, 14 September 2010) confirmed the two conditions set in AM&S Europe v Commission (1982): privilege attaches to communications connected with the rights of defence and emanating from an independent lawyer - defined as one "not bound to the client by a relationship of employment". An in-house lawyer's advice is not privileged in European Commission competition investigations, however senior the lawyer and whatever Bar they belong to; the Grand Chamber reasoned that employment compromises the independence on which the protection rests (EUR-Lex).

Two boundaries keep Akzo from swallowing everything. It governs EU-level proceedings - principally Commission competition enforcement - while national privilege law governs national proceedings, and several member states (the Netherlands, Belgium, Spain among them) do protect in-house advice domestically in varying degrees. And it bites hardest at the dawn raid: when Commission inspectors copy a legal department's files, the in-house analysis of the very conduct under investigation is readable evidence. That is why EU competition compliance programmes are built around early external-counsel involvement - the Akzo workaround is architectural, not clever drafting.

The comparison at a glance

Practical consequences for legal teams

Four disciplines follow from the map. Route by risk: where EU competition exposure or Indian investigative interest is plausible, involve external counsel from the start - in both regimes, external involvement is what converts unprotected analysis into privileged material. Control the loop: the UK client-group rule and the US legal-purpose test both reward small, deliberate circulation lists; "reply-all privilege" is a contradiction in terms. Label and segregate: legal advice separated from business commentary, litigation materials marked as prepared in anticipation - labels do not create privilege, but they preserve the arguments. Audit the archive: a legal department's files are read, in a raid or a summons, as they sit - which makes knowing what the archive contains a privilege-management task, not just an information-governance one. Structured, access-controlled matter files (see our note on confidentiality in legal AI workflows) are part of how modern teams keep that discipline real.

One forward-looking note for India: the 2025 ruling has sharpened the long-running debate - visible in bar commentary since - over whether Rule 49's incompatibility of employment and advocacy still serves its purpose, and whether in-house counsel should receive statutory protection of their own. Until legislation moves, the routing discipline above is the Indian answer.

How Judicio approaches confidentiality

Privilege discipline runs on infrastructure: knowing where sensitive analysis lives, who can see it, and what leaves the building. Judicio is built for that posture - client documents are encrypted, never used to train models, and governed by role-based access controls with an audit trail; research and review outputs cite their sources so a privilege log can trace what was derived from what; and the security page and methodology page document the controls in the depth privilege-conscious teams require.
