Blind-Eye Dishonesty Requires Targeted Suspicion and a Deliberate Decision Not to Inquire

Case: Grosvenor Property Developers Ltd v Portner Law Ltd

Citation: [2026] EWCA Civ 1238

Court: Court of Appeal (Civil Division)

Date: 2 October 2026

Judges: Phillips, Nugee and Falk LJJ

Introduction

This appeal concerned the boundary between serious professional misconduct and dishonesty. Grosvenor Property Developers Limited (“GPDL”), acting through its liquidators, alleged that Portner Law Limited was vicariously liable for a partner’s dishonest assistance in breaches of fiduciary duty committed by GPDL’s former directors.

Approximately £2.399 million beneficially belonging to GPDL, or its traceable proceeds, passed through the Firm’s client account in connection with an aborted property purchase, another property acquisition and refinancing, and a £2 million loan. The underlying misappropriation and the solicitor’s assistance were no longer disputed. The decisive issue was whether the solicitor had acted dishonestly.

The High Court found dishonest assistance, principally because an honest solicitor of equivalent experience would have made further inquiries, complied with anti-money laundering requirements and distinguished properly between the individuals and companies involved. The Court of Appeal held that this approach wrongly collapsed the subjective and objective stages of the dishonesty test and failed to apply the strict requirements of blind-eye knowledge.

Factual and Procedural Background

GPDL raised investment funds for a proposed student-accommodation development but entered liquidation after about £7 million was fraudulently misappropriated by its de jure and de facto directors. Some of those funds reached the Firm’s client account and were used in three groups of transactions:

  • an aborted purchase of a flat in Green Street, London;
  • the purchase, refinancing, transfer and eventual sale of a flat in Hallam Street, London; and
  • a £2 million loan made through Dare to Invest Limited.

The solicitor repeatedly failed to conduct adequate source-of-funds inquiries, accepted money from parties other than the named client, returned or transferred money to different accounts, gave inaccurate information to lenders and departed from the Firm’s policies and professional guidance. The High Court characterised this as persistent disregard of professional obligations and blind-eye dishonesty.

Nevertheless, the High Court also accepted important parts of the solicitor’s account: he genuinely believed that the family involved was legitimately wealthy; he understood that the father was funding his son’s property activities; and he was not shown to have known that the funds came from an outside victim such as GPDL.

Summary of the Judgment

Falk LJ, with whom Nugee and Phillips LJJ agreed, allowed the appeal, set aside the finding of dishonest assistance and substituted an order dismissing GPDL’s claim.

Core holdings

  1. Dishonesty requires a mandatory two-stage analysis. The court must first determine the defendant’s actual knowledge and beliefs about the facts. It must then assess the conduct, given that state of mind, against the objective standards of ordinary decent people.
  2. The first stage cannot be replaced by asking what an honest or diligent professional would have done. That formulation risks converting failures of care, professional standards or regulatory compliance into dishonesty.
  3. Blind-eye knowledge has two subjective requirements: a firmly grounded suspicion targeted at specific facts, and a conscious decision not to inquire because the defendant does not want confirmation of those facts.
  4. General awareness of risk is insufficient. Awareness that property transactions can be used for money laundering does not amount to suspicion that particular funds have been misappropriated.
  5. Recklessness is not dishonesty. Although it may be evidentially relevant, describing it as “strong evidence” of dishonesty risks obscuring the distinct legal tests.
  6. The findings supported negligence, not dishonesty. The solicitor knowingly cut corners and may have acted with serious professional laxity, but there was no finding of a targeted suspicion about the funds or a deliberate decision not to investigate for fear of discovering the truth.

Analysis

1. The mandatory two-stage test

The Court of Appeal treated Ivey v Genting Casinos (UK) Ltd (trading as Crockfords Club) [2017] UKSC 6, [2018] AC 391 as the proper starting point. The test is:

  1. ascertain subjectively the defendant’s actual knowledge or belief as to the facts; and
  2. decide objectively whether, given that state of mind, the conduct was dishonest by the standards of ordinary decent people.

A belief need not be reasonable, provided it is genuinely held. Its unreasonableness may be powerful evidence that the defendant did not truly hold it, but reasonableness is not an independent legal requirement. Equally, the defendant need not appreciate that ordinary people would regard the conduct as dishonest.

The High Court’s repeated question—whether an honest solicitor with the relevant experience would have acted in the same way—compressed these two stages into one. It also introduced professional diligence into the test. References to what a “conscientious”, “honest and diligent” or properly compliant solicitor would have done showed the danger: conduct may fall gravely below professional standards without being consciously improper.

2. Blind-eye knowledge

GPDL’s case depended on blind-eye, or “Nelsonian”, knowledge rather than actual knowledge of the fraud. The Court reaffirmed that blind-eye knowledge is treated as equivalent to actual knowledge, but only where both of the following are proved:

  • the defendant actually suspected that specified facts might exist; and
  • the defendant deliberately avoided inquiries in order not to obtain confirmation.

The suspicion must be firmly grounded and directed at specific facts. It is insufficient that a professional knows, in general terms, that property work or client accounts can facilitate fraud or money laundering.

The critical question is why no inquiry was made. If the reason is carelessness, workload, misplaced trust, incompetence or an unreasonable belief that nothing is wrong, dishonesty is not established. If the person suspects wrongdoing but avoids inquiry because the answer is unwelcome, blind-eye dishonesty may be proved.

The High Court expressly considered that suspicion of specific wrongdoing was unnecessary. That was a fundamental error. It had therefore made no finding that the solicitor suspected that the family or its companies were not entitled to the money, nor that he deliberately avoided inquiries for fear of discovering its true source.

3. Professional and anti-money laundering failures

The solicitor’s conduct departed from the Firm’s policies, the Law Society Anti-Money Laundering Practice Note 2013 and the relevant statutory framework, including the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017.

Such breaches may support disciplinary action, negligence claims or evidential inferences about a person’s state of mind. They do not, however, create a special dishonesty test for solicitors. Professional obligations are contextual evidence, not a substitute for proof of actual knowledge, belief or targeted suspicion.

4. Application to the findings of fact

Several findings undermined the claim:

  • The solicitor genuinely believed the family to be legitimately wealthy.
  • He understood the father to be financing his son’s property ventures.
  • GPDL failed to prove that he had previously formed a suspicion about the father’s honesty.
  • He was not found to know that deposits came from an unrelated external source rather than a company within the perceived family group.
  • There was no finding that he suspected that GPDL or another outsider had rights in the funds.

The inaccurate certificates, lender representations, breaches of undertakings and failures to distinguish between separate legal persons were serious. But they remained consistent with the accepted evidence that the solicitor treated the relevant individuals and companies as a single family economic unit.

Even the later correspondence from GPDL’s liquidators did not establish the necessary state of mind. The solicitor sought confirmation from another law firm before paying away sale proceeds, which tended against deliberate avoidance. His failure to notice that the response was incomplete could be extraordinary or negligent without proving that he consciously chose not to know the truth.

5. No retrial

The Court declined to remit the claim. GPDL had not advanced a targeted-suspicion case beyond factual allegations that it failed to establish at trial. A retrial was not the only just course and would unfairly give GPDL another opportunity to secure findings it had failed to obtain. The claim was therefore dismissed outright.

Precedents Cited

Foundational dishonesty authorities

Royal Brunei Airlines Sdn. Bhd. v Philip Tan Kok Ming [1995] 2 AC 378
Established dishonesty as an essential element of accessory liability. Lord Nicholls’ reference to conduct that an honest person would not undertake had to be read with his recognition that honesty contains a strong subjective element based on what the defendant actually knew.
Ivey v Genting Casinos (UK) Ltd (trading as Crockfords Club) [2017] UKSC 6, [2018] AC 391
Supplied the authoritative two-stage test. It also rejected the second limb of R v Ghosh [1982] QB 1053, under which the defendant had to realise that ordinary people would regard the conduct as dishonest.
Barlow Clowes International Ltd v Eurotrust International Ltd [2005] UKPC 37, [2006] 1 WLR 1476
Confirmed that dishonesty may consist either of knowledge that one cannot honestly participate in a transaction or of suspicion accompanied by a conscious decision not to inquire.
Twinsectra Ltd v Yardley [2002] 2 AC 164
Supported the treatment of deliberate abstention from inquiry as a form of knowledge, while later authorities clarified the applicable objective standard.

Blind-eye knowledge

Manifest Shipping Co Ltd v Uni-Polaris Insurance Co Ltd (The Star Sea) [2003] UKHL 1, [2003] 1 AC 469
Established that blind-eye knowledge requires both a firmly grounded, targeted suspicion and a deliberate decision not to seek confirmation. Speculative or untargeted suspicion cannot suffice.
Group Seven Ltd v Nasir [2019] EWCA Civ 614, [2020] Ch 129
Applied Ivey to dishonest assistance and confirmed that blind-eye knowledge is equivalent to actual knowledge only when the requirements in Manifest Shipping are met.
Stanford International Bank Ltd v HSBC Bank plc [2021] EWCA Civ 535, [2021] 1 WLR 3507
Reaffirmed that the subjective first stage cannot be bypassed. Allegations amounting to gross neglect, without a targeted suspicion and conscious avoidance, cannot sustain dishonest assistance.
Agip (Africa) Ltd v Jackson [1990] Ch 265
Provided the influential “why not?” inquiry: failure to draw inferences or ask questions is dishonest only where the person suspects wrongdoing and avoids the answer, not where the omission results from foolishness or misplaced reassurance.

The treatment of solicitors

Grupo Torras SA v Al-Sabah & Anor [2001] CLC 221
The High Court had treated this case as establishing an “honest solicitor” test. The Court of Appeal rejected that reading. Grupo Torras merely applied the existing law to a lawyer who knew that corporate funds were not freely available to the fraudulent directors, participated in sham structures and deliberately avoided obvious questions. It did not create a profession-specific test.
Clydesdale Bank Plc v Workman [2016] EWCA Civ 73
Emphasised that a court must confront a solicitor’s explanation directly before making a finding of dishonesty. The seriousness of such a finding demands careful consideration of what the professional says in their defence.

Recklessness and proof

R v G [2004] 1 AC 1034
Demonstrated that recklessness involves conscious appreciation and unreasonable taking of a risk, which is conceptually different from actual or blind-eye knowledge.
Potter v Canada Square Operations Ltd [2023] UKSC 41, [2024] AC 679
Reinforced the distinction between knowledge, including blind-eye knowledge, and recklessness. The Court suggested that “recklessness” is best avoided as a shorthand for dishonesty.
Three Rivers District Council v Governor and Company of the Bank of England (No 3) [2001] UKHL 16, [2003] 2 AC 1
Confirmed that dishonesty is proved on the balance of probabilities, but there must be evidence that tilts the balance from negligence toward dishonesty.
In re D (Secretary of State for Northern Ireland intervening) [2008] UKHL 33, [2008] 1 WLR 1499
Required courts to consider the gravity of the allegation and its consequences when deciding whether the civil standard has been satisfied.
Bank St Petersburg PJSC v Arkhangelsky [2020] EWCA Civ 408, [2020] 4 WLR 55
Further supported the careful evidential approach required for allegations of fraud or dishonesty.

Other relevant authorities

Atkinson v Varma [2020] EWHC 1963 (Ch) supplied background findings that the son involved in the transactions was trusting and naive rather than complicit in the underlying fraud. NatWest Markets Plc v Bilta (UK) Ltd [2021] EWCA Civ 680 was noted in relation to the treatment of blind-eye knowledge.

On whether a retrial should be ordered, the Court relied on Optis Cellular Technology LLC v Apple Retail UK Ltd [2025] EWCA Civ 552, [2025] RPC 18 and Simetra Global Assets Ltd v Ikon Finance Ltd [2019] EWCA Civ 1413, [2019] 4 WLR 112. A retrial is appropriate only where it is the sole just course.

Complex Concepts Simplified

Dishonest assistance
Liability imposed on a person who assists another’s breach of trust or fiduciary duty and does so dishonestly. It is accessory liability: the assistant need not be the person who originally owed the fiduciary duty.
Blind-eye or Nelsonian knowledge
Knowledge attributed to someone who actually suspects a specific fact and deliberately avoids checking because they do not want confirmation.
Subjective and objective stages
“Subjective” asks what this defendant genuinely knew or believed. “Objective” asks whether conduct based on that state of mind was dishonest by ordinary standards.
De jure and de facto director
A de jure director is formally appointed. A de facto director acts as a director in practice despite lacking formal appointment.
Traceable proceeds
Property substituted for misappropriated assets that equity can identify as representing the original property.
Vicarious liability
Liability imposed on an employer or firm for wrongful conduct committed by an employee or partner within the relevant scope of work.

Impact

The decision is important for dishonest-assistance claims against solicitors, banks, accountants and other regulated professionals. Claimants must plead and prove the defendant’s actual state of mind rather than relying on extensive regulatory failures or professional incompetence.

Courts should identify the particular fact suspected, the evidential basis for that suspicion and why the defendant failed to investigate. Findings framed only in terms of what an honest or competent professional “would have done” are insufficient.

The judgment does not weaken anti-money laundering duties or excuse misuse of client accounts. Such conduct may remain negligent, disciplinary, regulatory or even criminal depending on the evidence. The point is narrower: even gross negligence and knowing non-compliance do not automatically establish the mental state required for civil liability in dishonest assistance.

Conclusion

Grosvenor Property Developers Ltd v Portner Law Ltd draws a firm line between serious professional laxity and dishonesty. Blind-eye dishonesty requires proof of a specific, firmly grounded suspicion and a conscious decision not to inquire because the truth is feared. General awareness of risk, regulatory non-compliance, recklessness or repeated corner-cutting cannot replace that proof.

Because the accepted findings showed negligence but neither targeted suspicion nor deliberate avoidance, the Court of Appeal allowed the appeal and dismissed GPDL’s claim.
