Bolkiah v. KPMG
Factual and Procedural Background
The Appellant, formerly a senior government figure in The State and once Chair of Company B, retained Company A (a large international firm of chartered accountants headquartered in The City) to provide extensive forensic “litigation-support” services in 1996–1998. That engagement, codenamed “Project Lucy,” generated substantial confidential and privileged information about the Appellant’s worldwide assets.
Independently, Company A had audited Company B’s funds since 1983. In June 1998, after the Appellant’s relationship with his government deteriorated, Company B asked Company A to investigate large transfers of capital (the “special transfers”) that might implicate the Appellant. This new engagement—“Project Gemma”—was plainly adverse to the Appellant’s interests.
The Appellant, without being informed or asked for consent, sought an injunction to restrain Company A from acting on Project Gemma. Judge Pumfrey (first instance) granted the injunction. A majority of the Court of Appeal (headed by Judge Woolf) discharged it, holding that effective internal safeguards (“Chinese Walls”) removed any real risk of misuse. The Appellant appealed to the House of Lords, which allowed the appeal and restored the injunction.
Legal Issues Presented
- Does a firm that possesses confidential information from a former client breach its duty by accepting instructions from another client whose interests are adverse in a related matter?
- What is the proper legal test for determining whether internal information barriers (“Chinese Walls”) eliminate the risk of inadvertent disclosure or misuse of that confidential information?
- Where such a risk exists, on whom does the evidential burden lie, and what relief is appropriate?
Arguments of the Parties
Appellant's Arguments
- Absolute Duty of Confidence: The duty owed by a fiduciary continues after the retainer; it is unqualified and extends beyond deliberate disclosure to any avoidable risk of misuse.
- Chinese Walls Inadequate: The information barrier was erected ad hoc within a single department; rotational staffing and shared culture created an unacceptable risk of leakage.
- Consent Absent: The Appellant never consented to the re-engagement, and the earlier knowledge that Company A audited Company B did not amount to informed consent for an adverse forensic assignment.
Respondent's (Company A's) Arguments
- No Real Risk: Only personnel without confidential knowledge were placed on Project Gemma; separate offices, servers, and access controls ensured isolation.
- Undertaking Offered: A formal promise not to use or disclose any confidential information sufficiently protected the Appellant’s interests.
- Prejudice to Company B: Disqualification would significantly disrupt an ongoing governmental investigation and audit, and few alternative firms possessed the necessary resources.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Rakusen v. Ellis, Munday and Clarke [1912] 1 Ch 831 | No absolute bar on acting against a former client; restraint appropriate if risk of misuse of confidential information exists. | Confirmed as foundational but criticised as too lenient; Court adopted a stricter “no risk” standard. |
| Russell McVeagh McKenzie Bartleet v. Tower Corporation (NZ CA, 1998) | Balancing test weighing risk against competing interests. | Expressly rejected; House stated such balancing is inappropriate absent consent. |
| National Mutual Holdings Pty Ltd v. The Sentry Corporation (1989) 22 FCR 209 | Criticism of “reasonable probability of real mischief” test; call for stricter approach. | Cited approvingly to justify moving toward a “no risk” criterion. |
| Macdonald Estates v. Martin (1990) 77 DLR (4th) 249 | Introduced presumptions of shared confidences and shifted burden to the firm. | Relied upon for shifting evidential burden to Company A once possession of confidential information was established. |
| Kelly v. Cooper [1992] AC 205 | Clients may impliedly consent to parallel representations in non-confidential contexts (estate agents). | Used to distinguish audit services (where consent may be implied) from litigation-support services (where it is not). |
| Re a Firm of Solicitors [1997] Ch 1 | Formulated “no risk” test for disclosure. | Adopted as the governing standard. |
| Carindale Country Club Estate Pty Ltd v. Astill (1993) 115 ALR 112 | Articulated stringent protection of confidential information. | Cited in support of adopting a strict approach. |
Court's Reasoning and Analysis
1. Basis of Jurisdiction. The Court affirmed that intervention is grounded solely on the protection of confidential (and in part privileged) information, not on a general conflict-of-interest doctrine once the fiduciary relationship ends.
2. Duty of Confidence. The duty is unqualified: the former client is entitled to be free from any avoidable risk of disclosure. It is not merely a duty to take reasonable steps.
3. Standard of Risk. The Court rejected the “reasonable probability of real mischief” and “balancing” tests. Relief must be granted unless the Court is satisfied there is no real risk—however slight—of inadvertent disclosure.
4. Burden of Proof. Once the Appellant showed (a) possession of confidential information and (b) potential relevance to the new matter, the evidential burden shifted to Company A to prove that its safeguards eliminated the risk.
5. Evaluation of the Chinese Wall. The barrier was erected ad hoc within a single department, involved rotating staff, and depended largely on assurances from employees. The Court held that an effective wall must be an established, institutional structure; improvised measures within the same department could not satisfy the “no risk” standard.
6. Discretionary Factors. Arguments about inconvenience to Company B or scarcity of alternative advisers were irrelevant absent the Appellant’s informed consent.
Holding and Implications
HOLDING: The appeal was ALLOWED and the injunction restraining Company A from further work on Project Gemma was reinstated.
Implications: The decision imposes a stringent “no risk” test for professional firms possessing former-client confidences. Ad hoc Chinese Walls will rarely suffice; firms must have robust, pre-existing information-barrier systems or obtain explicit, informed consent before accepting adverse instructions. Although the ruling directly concerns accountants, the principles align them with solicitors, signalling tighter constraints on large multidisciplinary practices.
