Summary of Court of Appeal Opinion

Factual and Procedural Background

The Plaintiff was a long‑standing user of a betting exchange hosted by Company A (and its predecessors). Between 2009 and 2019 the Plaintiff sustained gambling losses of over £1.4 million. The Plaintiff, who owned a substantial portfolio of tenanted properties and derived significant rental income, sued Company A seeking to recover the majority of those losses on the basis that Company A knew or ought to have known that he was a problem gambler and therefore failed to act in accordance with social responsibility provisions in the Licence Conditions and Code of Practice (the LCCP) issued by the Regulator.

At first instance the trial judge, Judge Bird of the London Circuit Commercial Court, dismissed the claim. Judge Bird found that although expert psychiatrists agreed the Plaintiff had a gambling disorder (from at least 2015), Company A did not have actual or constructive knowledge that the Plaintiff was a problem gambler and did not breach the relevant LCCP provisions. Important factual findings included that Company A had made enquiries (including anti‑money‑laundering checks) about the Plaintiff's ability to fund losses, that the Plaintiff had provided information indicating substantial wealth, and that Company A had appropriate policies and applied them. The judge also held that Company A did not owe a relevant duty of care and that causation had not been established because the Plaintiff would have gambled elsewhere had Company A barred him. An alternative statutory/contractual argument based on s33 of the Gambling Act 2005 (to render bets void and permit a restitution/unjust enrichment claim) was also rejected.

The Plaintiff appealed to the Court of Appeal. Permission to appeal was granted by Judge Males on the basis that the proposed appeal raised issues of general importance about the responsibilities of gambling organisations. The lead judgment in the Court of Appeal was delivered by Judge Birss, with Judges Popplewell and Flaux agreeing.

Legal Issues Presented

1. Whether Company A knew or ought to have known that the Plaintiff was a problem gambler during the period 2009–2019 (and thereby breached the social responsibility provisions of the LCCP).
2. Whether Company A owed the Plaintiff a duty of care, and if so whether Company A breached that duty in negligence leading to recoverable loss (including issues of causation).
3. Whether, if Company A's policies and procedures were non‑compliant with the LCCP, the effect of section 33 of the Gambling Act 2005 is that gambling contracts entered into in breach of licensing conditions are void (with resulting restitution/unjust enrichment claims available to the Plaintiff).
4. Whether Company A's internal procedures and policies satisfied the LCCP requirement to include consideration of refusal of service/barring where a customer may be a problem gambler.

Arguments of the Parties

Plaintiff's Arguments

• The Plaintiff advanced a primary claim in negligence. He contended Company A owed him a duty of care to prevent the losses he incurred, that Company A breached the LCCP, and that breach amounted to a breach of the duty of care which caused his loss.
• The Plaintiff relied on factual features (including the scale and pattern of losses, frequency and size of bets, and certain account information disclosed during anti‑money‑laundering checks) to argue Company A knew or ought to have known he was a problem gambler.
• As an alternative remedy for a lesser amount, the Plaintiff argued that a breach of the LCCP (and thus of the licensing condition required by s24 and s82) meant that s33 rendered gambling contracts void, permitting restitution/unjust enrichment claims to recover stakes.
• The Plaintiff also argued that Company A’s policies did not contemplate ultimate refusal of service and therefore were non‑compliant with the LCCP.

Defendant's Arguments (Company A)

• Company A’s position (as found by the trial judge and not overturned on appeal) was that it did not know and could not reasonably have known that the Plaintiff was a problem gambler. The company had made enquiries (including repeated anti‑money‑laundering checks) and the Plaintiff provided information indicating substantial means to fund losses.
• Company A maintained it had appropriate policies and procedures aimed at identifying and assisting problem gamblers and that those policies evolved and were applied in practice; suspensions did occur but these were often due to AML checks rather than an acknowledgment of problem gambling.
• Company A contended that even if it had stopped the Plaintiff from using its exchange, the Plaintiff would have gambled elsewhere and therefore causation of the losses by any such omission was not established.
• Company A disputed that s33 of the Gambling Act operated to void betting contracts merely because the operator breached licensing conditions; the statutory scheme and public policy pointed against such a consequence.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
Precedent A (Calvert v William Hill)	Authority cited in relation to causation: that a gambler prevented from gambling on one platform might simply gamble elsewhere.	The trial judge had relied on this principle in doubting causation; the Court of Appeal treated the causation point as properly fact‑dependent and linked to the judge’s findings that the Plaintiff would have gambled elsewhere.
Precedent B (The Mayor and Burgesses of Haringey v Ahmed & Ahmed)	Standard of appellate review of factual findings (that a finding is unsupported by evidence and that no reasonable judge could have reached it).	The Plaintiff invoked this precedent to challenge the trial judge’s factual conclusions; the Court of Appeal rejected that challenge as the findings were supported by the evidence.
Precedent C (In Re B)	Referenced regarding the standards applicable when asserting a judge was wrong (appellate review principles).	Used to frame the Plaintiff’s submission that the judge erred; the Court of Appeal applied the correct standard of review and concluded the judge's factual conclusions were open on the evidence.
Precedent D (Fage UK Ltd v Chobani UK Ltd)	Passage cited in relation to the phenomenon of selective reliance on documents in appeals ("island hopping").	The Court of Appeal noted the tendency to focus on isolated documents and emphasised the broader evidential picture relied upon by the trial judge.
Precedent E (Housden v The Conservators of Wimbledon and Putney Commons)	Judicial caution about deciding issues unnecessarily and avoiding obiter dicta.	The Court of Appeal declined to decide grounds 2(a)–(c) (duty, breach, causation) for that reason, observing they were better decided in a factual context where necessary.
Precedent F (Okedina v Chikale)	Comprehensive guidance on statutory illegality of contracts and the approach to construing whether a statute intends to render contracts unenforceable.	The court treated Okedina as the starting point for the legal issue under s33 of the Gambling Act and applied its approach to decide that s33 did not imply a statutory prohibition voiding gambling contracts for operator breaches.
Precedent G (Cornelius v Phillips)	Earlier authority considered in the context of statutory illegality and public policy.	Cited as part of the body of authorities supporting the analytical approach to whether a statutory prohibition to void contracts should be implied; the court saw s33 as not operating to void contracts.
Precedent H (Phoenix Insurance v Halvanon Insurance)	Principle that even if one party is prohibited from entering a contract by statute, Parliament may not have intended contracts to be unenforceable by both parties; public policy considerations are central.	The Court of Appeal applied the reasoning in Phoenix by analogy, concluding that s33’s penalties are addressed to the operator and do not imply voiding all bets; public policy favoured enforceability of gambling contracts.
Precedent I (Hughes v Asset Managers plc)	Referenced among authorities on statutory construction and illegality.	Referred to when discussing the statutory construction exercise under Okedina; it formed part of the context for concluding s33 did not render bets void.

Court's Reasoning and Analysis

The Court of Appeal (Judge Birss) framed the principal issue as whether Company A knew or ought to have known that the Plaintiff was a problem gambler during 2009–2019. The Court treated that point as determinative of the appeal because the Plaintiff’s negligence claim and the alternative statutory/contractual argument under s33 both depended on overturning the trial judge’s factual finding on knowledge.

On the central factual question the court applied appellate review principles: the appeal challenged a finding of fact and therefore had to show the trial judge's conclusion was unsupported by the evidence or was one a reasonable judge could not reach. The court examined in detail the trial judge’s core findings (summarised at [128]–[132]) that Company A did not know and ought not to have known the Plaintiff had a gambling problem. Those findings rested on three main threads:

1. Evidence that the Plaintiff kept his problem to himself and actively misled Company A. The trial judge accepted testimony (for example from Attorney Rourke, the Plaintiff’s VIP manager at Company A) that the Plaintiff gave the impression of enjoying gambling, was calm, and did not disclose concerns about problematic behaviour. The Court of Appeal found that the inference that the Plaintiff hid his problem was open on the evidence.
2. Evidence indicating, on the face of the information provided to Company A (including in response to anti‑money‑laundering ("AML") enquiries), that the Plaintiff could afford his gambling losses. The trial judge reviewed numerous AML interactions where the Plaintiff provided information about income, remortgaging and sale of properties, and at a point Company A accepted the explanation of source of funds and reopened the account. The Court of Appeal accepted the judge was justified in concluding that the information presented indicated affordability and that this materially undermined the contention that Company A ought to have known of problem gambling.
3. The practical difficulty of identifying a problem gambler from betting data alone. The trial judge found it would have been very difficult to identify a problem gambler from data analysis at the relevant time. The Court of Appeal observed there was evidence in support of that conclusion and emphasised the broader evidential context rather than isolated documents relied upon by the Plaintiff.

On Company A’s policies, the Court of Appeal noted the trial judge had found Company A had appropriate policies that evolved over time and were driven by a desire to identify and assist problem gamblers. The Plaintiff’s contention that those policies did not contemplate outright refusal of service was addressed by accepting oral evidence from Attorney Lawson that, if suspicions were confirmed, complete account closure would follow. As the premise of the complaint about policies was therefore incorrect, no further construction of the LCCP provision was necessary.

Given the dismissal of the factual challenge on ground 1, the Court of Appeal declined to decide grounds 2(a)–(c) (duty of care, negligence and causation) as they were unnecessary to dispose of the appeal and would be best considered in an appropriate factual context (citing the general principle against deciding unnecessary issues).

On the statutory point (ground 3) concerning s33 of the Gambling Act 2005 (obiter), the court considered precedent on statutory illegality and the construction of provisions that might render contracts unenforceable (notably Okedina and Phoenix). The court concluded that s33 contains no express prohibition voiding contracts and that the text, scheme and policy of the Act point away from implying a general rule that operator breach of licensing conditions renders all bets void. The Court relied on the following strands of reasoning:

• The statutory framework focuses penalties on the operator and provides the Regulator with specific powers (for example under s336) to void unfair bets; this would sit uneasily with an implied prohibition voiding all contracts for any licensing breach.
• Public policy considerations: depriving successful gamblers of winnings, or enabling every losing gambler to avoid payment on the basis of any licensing breach, would be contrary to sensible policy and the overall scheme of the Act which contemplates enforceability of gambling contracts in general.
• Analogy with authorities (such as Phoenix) where the court should be cautious about implying that statutory prohibitions render contractual obligations unenforceable by both parties; the relevant question is one of statutory construction and public policy.

Summarily, the Court of Appeal found no basis to overturn the trial judge’s factual findings that Company A did not know and ought not to have known that the Plaintiff was a problem gambler, upheld the finding that Company A had appropriate policies and procedures in place, and rejected the submission that s33 renders bets void and permits restitutionary recovery on that basis.

Holding and Implications

APPEAL DISMISSED

Holding: The Court of Appeal dismissed the Plaintiff's appeal. It upheld the trial judge’s factual finding that Company A neither knew nor ought to have known that the Plaintiff was a problem gambler for the period in question and concluded there was no breach of the relevant LCCP provisions on the evidence. The court also rejected the legal submission that s33 of the Gambling Act 2005 operates to render gambling contracts void for operator breaches of licensing conditions.

Implications: The direct effect is that the Plaintiff’s claim for damages in negligence was dismissed and the alternative restitution/unjust enrichment argument based on s33 failed. The Court did not decide the broader negligence issues (duty, breach and causation) because they were unnecessary given the dispositive factual finding. The court’s reasoning on s33 was obiter but authoritative on the point: the statutory scheme and public policy do not support treating operator breach of licensing conditions as automatically voiding gambling contracts. No new binding precedent on negligence duty or causation was established by the Court of Appeal beyond the factual conclusions in this case.
