Appellate restraint in Quincecare “put on inquiry” findings and demand-based limits on s.35A interest for account reconstitution

Case: Moorwand Ltd v Hamblin & Ors
Citation: [2026] EWCA Civ 942
Court: Court of Appeal (Civil Division), England and Wales
Date: 21 July 2026
Judges: Peter Jackson LJ, Nugee LJ, Foxton LJ (judgment of Foxton LJ)

1) Introduction

This second appeal arose out of an “authorised push payment” (APP) fraud. A fraudster (“X”) incorporated a company (“RND”) using a real individual’s stolen identity, opened electronic money accounts with an FCA-regulated electronic money institution (“the EMI”), and induced private investors (“the investors”) to transfer £160,000 which was rapidly dissipated through Bitcoin purchases and other payments.

The investors restored RND to the register and pursued a derivative claim in RND’s name against the EMI, contending that RND held the £160,000 on constructive trust for them and that the EMI breached the Quincecare duty by executing payment instructions when it should have been “put on inquiry” that the instructions were unauthorised (i.e., a misappropriation from RND). They also advanced a claim under the Payment Services Regulations 2009, and later sought interest on an account reconstitution/debt analysis.

At first instance (a two-day trial), the trial judge dismissed the operational/breach case (finding no Quincecare breach and that the payments were authorised for Payment Services Regulations purposes) and held liability excluded by a contractual exclusion clause. On appeal, Marcus Smith J reversed on Quincecare, held the claim was properly framed as reconstituting the account (debt), ordered the EMI to re-credit £160,000, and then awarded statutory interest from the dates of the transfers.

The Court of Appeal restored the trial judge’s dismissal. The central theme is not a new expansion of Quincecare; rather, it is a sharp reminder of (i) the difficulty of overturning evaluative, fact-sensitive “put on inquiry” findings on appeal, and (ii) the orthodox “demand” requirement limiting when a cause of action accrues for statutory interest on reconstitution-type claims.

2) Summary of the Judgment

  • Liability: The Court of Appeal allowed the EMI’s appeal. The High Court judge should not have interfered with the trial judge’s evaluative finding that the EMI was not put on inquiry that the payment instructions were an attempt to misappropriate RND’s funds. The alleged “errors of law” identified by the High Court judge were not made out on a fair reading of the trial judgment.
  • Pleadings point: The investors were not confined to an argument that only the real identity-theft victim could authorise instructions; the pleaded case also alleged that the account activity was obviously inconsistent with legitimate corporate purposes and thus unauthorised.
  • Authority/identity: The Court of Appeal held it would be wrong to treat the identity-theft victim as the person authorised to act for RND; company membership/directorship requires consent (Companies Act 2006; Re JDK Construction Ltd [2024] EWCA Civ 934, [2024] Bus LR 1694).
  • Interest (s.35A): Even if the investors had succeeded on account reconstitution (debt), statutory interest under s.35A Senior Courts Act 1981 generally runs only once a cause of action has accrued; for bank-type deposits that typically requires a demand (Joachimson v Swiss Bank Corp [1921] 3 KB 110; National Bank of Commerce v National Westminster Bank plc [1990] 2 Lloyd's Rep 514; cited via Sagicor Bank Jamaica Ltd v Seaton [2022] UKPC 48, [2023] 1 WLR 1759). The High Court interest award from the transfer dates was therefore wrong in principle (though the point became academic given the liability outcome).
  • Costs warning: Peter Jackson LJ recorded the striking disproportionality of costs (around £1m) to the sum in dispute, echoing Piglowska v Piglowski [1999] UKHL 27; [1999] 1 WLR 1360.

3) Analysis

3.1 Precedents cited and their influence

(A) The Quincecare line and APP fraud

  • Barclays Bank plc v Quincecare Ltd [1992] 4 All ER 363
    Quincecare established the “put on inquiry” threshold: where a bank has reasonable grounds for believing an agent’s instruction is an attempt to misappropriate funds, it must refrain from executing without inquiry. The present case was treated as a conventional Quincecare scenario (instructions given “on behalf of” a corporate customer), not as the Philipp scenario (customer personally instructing).
  • Philipp v Barclays Bank UK Plc [2023] UKSC 25, [2024] AC 346
    Philipp confined Quincecare in APP contexts where the customer itself gives unequivocal instructions: banks have a strict duty to execute and are not responsible for the wisdom of payment decisions. But Philipp also clarified that where an agent gives instructions, and the bank is “put on inquiry,” executing without inquiry is outside mandate and supports “reconstitution” of the account (Lord Leggatt at [96]-[97]). In Moorwand, that conceptual architecture mattered, but the dispositive question remained factual: was the EMI put on inquiry on the evidence?
  • JP SPC 4 v Royal Bank of Scotland International Ltd [2022] UKPC 18, [2023] AC 461
    The Privy Council rejected an extension of Quincecare-type duties to third-party beneficial owners. The Court of Appeal noted the investors’ attempt to obtain a similar practical outcome via a derivative claim on behalf of the payee vehicle (RND), highlighting how constructive trust/derivative mechanisms can re-route loss in ways a direct tort claim cannot—while still turning on the customer-facing Quincecare test.

(B) Attribution, corporate separateness, and “fraudster companies”

  • Stone & Rolls Ltd (in liquidation) v Moore Stephens (A Firm) [2009] UKHL 39, [2009] 1 AC 1391, Bilta (UK) Ltd v. Nazir [2015] UKSC 23, [2016] AC 1, and Singularis v Daiwa [2019] UKSC 50, [2020] AC 1190
    These authorities address when an agent’s fraud/knowledge is attributed to a company, and how purpose/context controls attribution. Marcus Smith J had criticised the trial judge for “eliding” agent and principal and (as he saw it) failing to treat RND as an “innocent principal” victimised by X. The Court of Appeal held this critique misfired because the trial judge did not decide the case by attributing X’s wrongdoing to RND (nor on actual authority, illegality, or circuity grounds). The trial judge assumed the relevant question was whether the EMI was on notice such that it could not rely on ostensible authority.
  • Brink's-Mat Ltd v Noye [1991] 1 Bank LR 68
    This was used to illustrate that even a company used as a vehicle can still be treated as a separate legal person and, in a relevant sense, a “victim” of wrongful depletion of its assets; and that it can be arguable that a bank should have appreciated wrongdoing to the company. The Court of Appeal in Moorwand deployed Brink’s-Mat mainly as context for the kind of arguments that may arise in future cases, rather than as a basis to overturn the trial judge’s factual conclusions.
  • Prest v Petrodel Resources Ltd [2013] UKSC 34, [2013] 2 AC 415
    Mentioned in passing to acknowledge that “veil piercing” may sometimes be available under the “evasion” principle, but it was not engaged by the issues that actually had to be decided.

(C) Trust/derivative standing

  • Halley v Law Society [2003] EWCA Civ 97, [2003] WTLR 845
    The trial judge relied on Halley to hold that RND held the £160,000 on constructive trust for the investors and that this underpinned derivative standing. Notably, the derivative action and trust findings were not reopened on appeal; the Court of Appeal’s focus remained the Quincecare “put on inquiry” assessment and appellate standards.

(D) Corporate consent to office/membership

  • Re JDK Construction Ltd [2024] EWCA Civ 934, [2024] Bus LR 1694
    Cited to support the proposition that mere entry on a register is insufficient to make someone a member absent assent, reinforcing that the identity-theft victim could not be treated as RND’s authorised decision-maker.
  • Shogun Finance Ltd v Hudson [2003] UKHL 62, [2004] 1 AC 919
    Mentioned as an example of “person you are dealing with” reasoning in a different context; the Court of Appeal deliberately avoided deciding whether (and how) such analysis mapped onto the “who is the shareholder/director?” question for a company incorporated through identity fraud, because it was unnecessary to resolve the appeal.

(E) Interest and accrual of a cause of action

  • Sagicor Bank Jamaica Ltd v Seaton [2022] UKPC 48, [2023] 1 WLR 1759
    Confirmed that wrongful debiting is treated as a debt/reconstitution type claim rather than merely declaratory. However, statutory interest still requires the cause of action to have accrued.
  • Joachimson v Swiss Bank Corp [1921] 3 KB 110 and National Bank of Commerce v National Westminster Bank plc [1990] 2 Lloyd's Rep 514
    These supply the classical rule: a credit balance becomes payable on demand, and (on one view) a cause of action for wrongful debiting similarly accrues on demand, not at the moment of transfer. The High Court’s contrary approach (interest from transfer dates based on what would “in substance” have happened) was held inconsistent with the statutory requirement that interest runs only once a cause of action has arisen.
  • Abraaj Investment Management Ltd v KES Power Ltd [2026] EWHC 441 (Comm) and Odyssey Aviation Limited v GFG 737 Limited [2019] EWHC 1980 (Comm)
    Cited for the principle that purely declaratory claims do not found s.35A interest—reinforcing the need to identify when a payable obligation (and thus a cause of action) crystallised.

3.2 Legal reasoning

(A) What the Court of Appeal treated as the real issue

The Court of Appeal accepted that, absent “put on inquiry,” the person operating RND’s account appeared to have authority under the contractual mandate and communications channels. The trial judge’s decision was not that X had actual authority (no such case was pleaded or run), nor that illegality defeated the claim (it was unpleaded and abandoned on appeal). It was the narrower, orthodox Quincecare issue: were there reasonable grounds for the EMI to believe the instructions were an attempt to misappropriate RND’s funds such that it had to pause and inquire?

(B) Why the High Court judge’s “errors of law” were rejected

  • “Eliding agent and principal”: Marcus Smith J criticised the trial judge for treating X and RND as “one and the same” and not assessing matters from the standpoint of an innocent corporate principal, invoking Bilta and Singularis. The Court of Appeal held this criticism would only bite if the trial decision depended on attribution (e.g., actual authority, illegality, circuity). It did not. The trial judge’s repeated references to “authorised” were, when read fairly and in context, references to how matters appeared “on their face” to the EMI for ostensible authority and “put on inquiry” purposes.
  • “Only the real individual could authorise”: If the High Court judge meant that the identity-theft victim was the authorised actor for RND, that was wrong in law: corporate office/membership cannot be imposed without consent (Companies Act 2006; Re JDK Construction Ltd). In any event, the Court of Appeal emphasised this point was not decisive to the trial judge’s reasoning, which turned on notice/enquiry.
  • The “ipso facto” regulatory relevance error: The Court of Appeal agreed with the abstract proposition that facts grounding AML/regulatory failures can also be relevant to Quincecare; it is wrong to say “regulatory” equals “irrelevant” as a matter of law. But it found that the trial judge, properly read, did not commit that legal error: he (and the single joint expert as he interpreted the report) treated the onboarding deficiencies as existing “despite” which there was still no reason to suspect misappropriation of RND’s funds at the time of the transfers.

(C) Appellate restraint: the controlling principle in the outcome

Having rejected the alleged errors of principle, the Court of Appeal held that the “high threshold” for disturbing the trial judge’s evaluative factual conclusion was not met. The expert report was ambivalent and neither party tested it in cross-examination; the trial judge’s interpretation was within the range of permissible readings. Once the appeal was properly framed as an attempt to re-weigh an evaluative “put on inquiry” assessment, it failed.

(D) Statutory interest: the demand requirement as a hard edge to s.35A

The Court of Appeal treated the s.35A issue as turning on statutory structure: interest runs only from the date the cause of action arises. Even if the remedy is “reconstitution” in debt, the cause of action for a credit balance (and arguably for wrongful debiting) generally requires demand. A court cannot circumvent that by hypothesising that, but for the wrong, the customer would have demanded and paid away the balance (even to a beneficiary under a trust). A late alternative argument—dissolution ending the relationship so no demand was needed—was noted but not decided.

3.3 Impact

(A) Quincecare in “payee-vehicle” APP fraud litigation

Moorwand illustrates both the attraction and the fragility of using a payee vehicle (and derivative standing via constructive trust) to pursue what is, in practical terms, a “receiving institution” claim—particularly after Philipp and JP SPC 4. The Court of Appeal did not shut that route down in principle; instead, it shows how fact-sensitive and evidence-dependent the “put on inquiry” threshold is, and how difficult it is to overturn a trial judge’s assessment once properly reasoned.

(B) Regulatory failings: relevant facts, but no automatic private-law conversion

The Court of Appeal reaffirmed the distinction between (i) breach of regulatory obligations (which may be non-actionable in private law) and (ii) the factual matrix those obligations address (which may still be relevant to whether the institution had reasonable grounds to suspect misappropriation). The key practical lesson is evidential: parties must prove how those facts bear on “reasonable grounds” at the time of the payments, not merely that AML processes were imperfect.

(C) Interest on reconstitution: a likely future battleground

The demand-based analysis constrains claimants seeking statutory interest on wrongly debited balances, particularly in electronic money contexts where (as the High Court noted) contract interest may be prohibited (Regulation 45 of the Electronic Money Regulations 2011). Unless and until the “demand” requirement is satisfied (or a recognised exception applies, such as account closure/termination), s.35A interest may not run.

(D) Litigation economics

The Court’s express concern about disproportionate costs is a policy signal to litigants and case managers in fraud and payments litigation: even where doctrinal routes exist, the economics can overwhelm the claim.

4) Complex concepts simplified

  • APP fraud: the victim is persuaded to authorise a payment (a “push”); it is not an unauthorised “pull” by the fraudster.
  • Quincecare duty: where a bank/PSP receives an instruction from an agent of the customer, it must pause and make inquiries if it has reasonable grounds to believe the instruction is a fraud on the customer (“put on inquiry”). If it pays without inquiry in those circumstances, it may be acting outside its mandate (Philipp).
  • Actual vs ostensible authority: an agent may appear authorised to outsiders (ostensible authority) even when the agent is not truly authorised (actual authority). Quincecare is concerned with when warning signs are sufficient that the bank cannot safely rely on appearances without checking.
  • Constructive trust: a trust imposed by law to prevent unjust enrichment or to respond to wrongdoing; here, it was found (unchallenged on appeal) that the payee company held the received funds for the investors, enabling a derivative claim.
  • Derivative claim (in this setting): the beneficiary sues in the company’s name to enforce the company’s rights (e.g., against its bank/PSP), because the company itself will not sue (often because it is controlled by wrongdoers or defunct).
  • Reconstitution / “debt” analysis: if a payment was outside mandate, the bank/PSP is not entitled to debit the account; the remedy is to restore the balance, rather than (necessarily) prove consequential-loss damages.
  • Demand requirement: traditionally, a bank deposit is payable only on demand; without demand, a cause of action (and thus statutory interest) may not accrue, even if a “wrongful debit” occurred.

5) Conclusion

Moorwand Ltd v Hamblin & Ors [2026] EWCA Civ 942 is a significant appellate-level statement about method rather than expansion: Quincecare “put on inquiry” disputes are intensely evaluative, and absent a genuine legal error, appeal courts will not re-run the factual assessment. The decision also clarifies that, even where a claimant frames relief as account reconstitution (debt), statutory interest under s.35A Senior Courts Act 1981 generally depends on when the cause of action accrues—often requiring a demand—so courts cannot award interest from the transfer date simply because that feels like economic restitution.
