Special Commissioner and Another, Ex P Morgan Grenfell & Co Ltd, R v.
Factual and Procedural Background
During the 1990s the Appellants, an investment bank, promoted a tax-planning scheme that generated chargeable gains for clients—one such client being Company B. The scheme’s success depended on the treatment of a premium paid by the Appellants for a long lease as a revenue, rather than capital, expense. Agency A (the United Kingdom tax authority) disputed this treatment and, on 28 September 1999, issued a statutory notice under section 20(1) of the Taxes Management Act 1970 requiring production of the Appellants’ privileged legal advice concerning the scheme.
The Appellants commenced judicial review proceedings to quash the notice. The Divisional Court and, subsequently, the Court of Appeal upheld the notice. The only point pursued before the House of Lords was whether section 20(1) empowers Agency A to compel production of documents protected by legal professional privilege (LPP). Five Law Lords (Judge Nicholls, Judge Hoffmann, Judge Hope, Judge Hobhouse and Judge Scott) heard the appeal.
Legal Issues Presented
- Whether section 20(1) of the Taxes Management Act 1970, properly construed, authorises Agency A to require a taxpayer to produce documents that are subject to legal professional privilege.
Arguments of the Parties
Appellants' Arguments
- LPP is a fundamental common-law right and may be overridden only by express words or necessary implication, neither of which is present in section 20(1).
- The statutory safeguards elsewhere in sections 20–20D show Parliament’s intention to preserve, not abolish, LPP.
- Requiring production of privileged advice would undermine the right of access to confidential legal counsel and, potentially, Article 8 privacy rights.
Respondents' (Agency A’s) Arguments
- Section 20(1) uses general language—“such documents as are in the person’s possession or power”—broad enough to encompass privileged material.
- The Act already creates specific protections for documents in the possession of lawyers (e.g., sections 20B(8) and 20C(3)); by necessary implication, documents in the taxpayer’s own hands are not protected.
- Access to privileged advice is necessary to establish the taxpayer’s purpose in complex avoidance arrangements.

Court's Reasoning and Analysis
The House began by reaffirming that legal professional privilege is an “absolute and fundamental” right, integral to both the common law and international human-rights instruments. General statutory language must therefore be read subject to that right unless Parliament expressly states, or by necessary implication makes clear, an intention to override it.
Section 20(1) contains no express reference to LPP. The Respondents argued that other safeguards within sections 20–20D implied that documents in a taxpayer’s own hands were not privileged. The House rejected this for several reasons:
- The various safeguards (judicial consent, restrictions on notices to professionals, limited litigation privilege, accountants’ working-paper protections) addressed different concerns and did not logically suggest an intention to abrogate LPP.
- Sections 20B(8) and 20C(3) expressly preserve LPP for documents held by lawyers. The Respondents’ inference—that silence about taxpayer-held documents implied their vulnerability—would create an irrational distinction whereby identical documents would be privileged in the lawyer’s possession but not in the client’s.
- The historical judgment in Parry-Jones v Law Society was not decisive; Parliament’s inclusion of specific lawyer-focused protections could be explained as belt-and-braces drafting in light of that decision, not as a signal that taxpayer-held documents were unprotected.
- Parliamentary debates offered no clear statement that the legislation was meant to curtail LPP.
- Given that LPP can be overridden only where “absolutely necessary,” and that the statute’s language fell “a long way short” of a necessary implication, the privilege must remain intact.
The House concluded that section 20(1) does not empower Agency A to require production of privileged documents.
Holding and Implications
APPEAL ALLOWED; NOTICE QUASHED
The decision restores the primacy of legal professional privilege in tax investigations: taxpayers cannot be compelled, under section 20(1) of the Taxes Management Act 1970, to disclose privileged legal advice. The ruling does not establish a new doctrine but emphatically reaffirms that fundamental common-law rights survive unless Parliament expressly—or by unavoidable implication—removes them.
