Mather v Rattan

Smart Summary

Anonymized Summary of Court of Appeal Opinion

Factual and Procedural Background

Between December 2012 and November 2014 the Plaintiffs invested a total of £1,000,000 to acquire shares in a biotechnology company (hereinafter "Company A"). The Defendant was a director and the majority shareholder of Company A. Company A subsequently entered administration on 26 April 2016, leaving the Plaintiffs' shares worthless and resulting in the loss of their investment.

The Plaintiffs commenced proceedings for fraudulent misrepresentation against the Defendant on 20 August 2021. After a four-day trial, Judge Hodge (in a reserved judgment reported at [2025] EWHC 438 (Ch)) found that the Plaintiffs invested in reliance on statements made by the Defendant in an e-mail dated 5 December 2012. In that e-mail the Defendant stated that a named individual (hereinafter "Person A") had been allowed to become a director of Company A. The trial judge found that this representation was false and known by the Defendant to be false because Person A had not been formally appointed as a director until 12 September 2015.

The trial judge found that the Plaintiffs relied on the Defendant's representations when making their investments, that the reliance caused the Plaintiffs' loss (the full amount invested), and that the claim was not statute-barred under section 32 of the Limitation Act 1980. The judge awarded the Plaintiffs £1,000,000 in damages, plus interest and costs.

The Defendant was granted permission to appeal by Judge Arnold on three grounds, which are addressed by the Court of Appeal and dismissed by the panel comprising Judge Snowden, Judge Males and Judge Lewison.

Legal Issues Presented

  1. Whether the Plaintiffs' claim for fraudulent misrepresentation was statute-barred under the Limitation Act 1980, in particular whether section 32 prevented time from beginning to run because the Plaintiffs could not, with reasonable diligence, have discovered the fraud earlier.
  2. Whether the Plaintiffs in fact relied upon the Defendant's representation that Person A had been appointed a director of Company A (the issue of reliance), given the Defendant's contention that Person A was a de facto director.
  3. Whether the misrepresentation caused the Plaintiffs' loss (causation), or whether the loss would have occurred in any event because of the failure of Company A's business.

Arguments of the Parties

Appellant's Arguments (Defendant)

  • Ground 1 (Limitation): The trial judge wrongly shifted the burden of proof. The Defendant argued that the Plaintiffs bore the burden under section 32 to prove that they could not, with reasonable diligence, have discovered Person A was not a director (for example by searching the Companies Registry), and the Plaintiffs' evidence did not explain why they had not undertaken such inquiries.
  • Ground 2 (Reliance): The trial judge erred in finding reliance on the assertion that Person A was a de jure director because, it was said, Person A had acted as a de facto director and the Plaintiffs would have been content with Person A's de facto status; therefore the misrepresentation as to formal appointment was immaterial.
  • Ground 3 (Causation): The trial judge stopped at reliance and did not properly examine causation. The Defendant argued the judge should have considered the counterfactual of what the Plaintiffs would have done if the e-mail had not misrepresented that Person A was a de jure director (and that the Plaintiffs would nonetheless have invested), such that the true cause of loss was Company A's business failure rather than the misrepresentation.

Respondent's Arguments (Plaintiffs / Attorney Vickers)

  • The Plaintiffs relied upon the Defendant's explicit representation that Person A had been appointed as a director and that representation induced them to invest; they had no reason to doubt the Defendant's veracity or to conduct registry searches.
  • On limitation, the Plaintiffs' evidence showed that nothing put them on inquiry until September 2015 (a call from Person A and other investor concerns), which was within six years of the claim being issued; therefore section 32 prevented time from running earlier.
  • On causation, the Plaintiffs relied on established authorities on deceit (including Smith New Court) to show that the loss flowing directly from the fraudulent inducement was recoverable; the trial evidence supported that the misrepresentation induced the investments and that shares had no realisable value by the time the Plaintiffs were on notice.

Table of Precedents Cited

Precedent Rule or Principle Cited For Application by the Court
Paragon Finance plc v DB Thakerar [1999] 1 All ER 400 Explains section 32 Limitation Act test: burden on plaintiff to show they could not, with reasonable diligence, have discovered the fraud; plaintiffs must show discovery would have required exceptional measures they could not reasonably have been expected to take. The Court cited the passage to frame the burden under section 32 and held that the trial judge applied this test correctly in finding that the Plaintiffs had discharged the burden.
OT Computers Ltd v Infineon Technologies [2021] QB 1183 Clarifies the two-stage approach to reasonable diligence: (1) whether something put the claimant on notice to investigate and (2) what a reasonably diligent investigation would have revealed; the test remains a single statutory issue applied objectively to the actual claimant. The Court relied on this exposition to support the conclusion that nothing put the Plaintiffs on inquiry about Person A's formal status until September 2015, so they were not required to have made earlier searches at Companies House.
Gresport Finance v Battaglia [2018] EWCA Civ 450 Statement (per Henderson LJ) that reasonable diligence only makes sense if there is something to put the claimant on notice of the need to investigate. Used (via OT Computers) to justify focusing on whether there was anything to put the Plaintiffs on inquiry before September 2015; the Court concluded there was not.
Volpi v Volpi [2022] 4 WLR 48 Principle of appellate deference to trial judge findings of primary fact; the Court of Appeal will not disturb findings unless plainly wrong. The Court invoked the authority to explain why it would not overturn the trial judge's factual findings about reliance and causation absent a clear error.
Smith New Court Securities v Citibank [1997] AC 254 Sets out causation and measure of damages in deceit: claimant is entitled to recover losses directly flowing from the transaction induced by fraud, including the full price paid subject to credit for any benefits received; identifies circumstances in which the general rule may not be inflexibly applied. The Court applied this principle to hold that the Plaintiffs were entitled to recover the full amount invested because the misrepresentation directly induced the investment, the misrepresentation continued to operate, and the Plaintiffs were effectively locked into the investment until they were put on notice.
MDW Holdings v Norvill [2023] 4 WLR 33 Recognises that, in theory, a defendant may seek to prove that the claimant would have entered an alternative transaction and suffered the same loss absent the misrepresentation. The Court acknowledged the authority but held that on the facts as found by the trial judge this line of argument was impossible: the trial evidence established that the Plaintiffs would not have invested but for the misrepresentation.
Rea v Rea [2022] EWCA Civ 195 Discusses the proper role of a judge in asking questions on behalf of unrepresented litigants and warns against an inquisitorial approach. The Court relied on this authority to explain that it would not be appropriate for the trial judge (or appellate court) to adopt an inquisitorial role to pursue factual hypotheses favourable to the Defendant that were not explored at trial.
Trial judgment: HHJ Hodge KC, [2025] EWHC 438 (Ch) Factual findings and initial application of law: found false representation, reliance, causation and that section 32 prevented limitation from barring the claim; awarded damages of £1,000,000 plus interest and costs. The Court of Appeal treated these findings as primary findings of fact and upheld them, explaining why the trial judge correctly applied legal tests and why the appeal failed on the pleaded grounds.

Court's Reasoning and Analysis

The Court of Appeal considered each ground of appeal in turn and analysed both the legal principles and the factual findings on which the trial judge based his decision.

Ground 1 — Limitation (section 32)

The Court reviewed the statutory text of section 32 and leading authorities on its interpretation. It accepted that the burden under section 32 is on the Plaintiffs to prove they could not, with reasonable diligence, have discovered the fraud earlier (Paragon). The Court rejected the Defendant's submission that the trial judge had misallocated the burden, explaining that, taken in context, the trial judge had correctly recognised that the Plaintiffs bore the burden and had found that their evidence sufficiently answered the Defendant's primary limitation plea.

Applying the guidance in OT Computers and Gresport Finance about the "trigger" for reasonable diligence, the Court concluded that there was nothing before September 2015 to put the Plaintiffs on inquiry. The promises about Person A's appointment were framed (as shown in the Defendant's own email) as a means of protecting the Plaintiffs' investment; the Plaintiffs had no reason to check Company A's formal records until they developed cause for concern (in particular, a call from Person A in September 2015 and independent investor enquiries). On that factual basis the Court upheld the trial judge's conclusion that the claim was brought within time.

Ground 2 — Reliance

The Court rejected the Defendant's argument that the Plaintiffs would have been satisfied by Person A acting as a de facto director. Two reasons were given:

  • The Plaintiffs' evidence about wanting Person A "to have an influence and a say" was given in the context of Person A being on the board in a formal (de jure) capacity; the evidence did not support the proposition that the Plaintiffs would have accepted a lesser, informal status.
  • The Defendant's contention that Person A was already acting as a de facto director at the material time was not established on the pleadings or at trial, nor was it a matter of common ground or a factual finding by the trial judge. The limited evidence that might have supported such a contention was not developed at trial and the judge made no findings to that effect.

Given the trial judge's primary fact findings about reliance (including direct evidence from the Plaintiff that they would not have invested but for the Defendant's assurance), the Court declined to interfere under the usual appellate standard of review.

Ground 3 — Causation

The Court set out the settled law on causation in deceit (Smith New Court and related authority): a claimant induced by fraud may recover the financial loss directly flowing from the induced transaction, generally including the full price paid but with credit for any benefits received; the loss must be directly caused by the transaction and the claimant must mitigate once on notice.

The Court held that the Defendant's counterfactual argument (that the Plaintiffs would have invested in any event and thus the Company failure, not the misrepresentation, caused the loss) could not succeed on the facts found by the trial judge. The trial judge accepted direct testimony that the Plaintiffs would not have invested but for the representation that Person A had been made a director. The Court emphasised that it would not be appropriate for the trial judge (or appellate court) to conduct an inquisitorial fact-finding exercise to pursue hypothetical scenarios that were not argued or explored at trial.

The Court further noted that there was no evidence of any immediately realisable value in the shares at any relevant time, that the misrepresentation continued to operate and that the Plaintiffs were effectively locked into the investment until they were put on inquiry in mid-September 2015; on those grounds the full investment amount was recoverable.

Holding and Implications

APPEAL DISMISSED.

Holding: The Court of Appeal dismissed the Defendant's appeal on all grounds. It affirmed the trial judge's findings that the Plaintiffs relied upon the Defendant's fraudulent misrepresentation in the e-mail of 5 December 2012, that the misrepresentation caused the Plaintiffs' loss, and that the claim was not statute-barred because the Plaintiffs could not, with reasonable diligence, have discovered the fraud before September 2015. The trial award of £1,000,000 in damages (together with interest and costs) was thus upheld.

Implications: The decision confirms the application of established principles on limitation (section 32), reliance and causation in deceit claims. On the facts of this case the Court emphasised (i) the necessity for something to put a claimant on inquiry before the duty of reasonable diligence is triggered, (ii) the appellate court's reluctance to overturn primary findings of fact, and (iii) that, where a misrepresentation directly induces a purchase and the misrepresentation continues to operate so that the claimant is locked into the transaction, the claimant may recover the full price paid. The opinion does not purport to establish new legal principle beyond the application of existing authorities to the facts of this case; its effect is to affirm the trial outcome and the applicable legal tests.
