Ivey v Genting Casinos (T/A Crockfords Club) (2017)


The subjective element of the test for dishonesty in R. v Ghosh (Deb Baran) [1982] Q.B. 1053 did not correctly represent the law and directions based on it should no longer be given. When dishonesty was in question, the fact-finding tribunal had first to ascertain the actual state of the individual's knowledge or belief as to the facts. The question whether the conduct was honest or dishonest was then to be determined by applying the objective standards of ordinary decent people.


A professional gambler appealed against a decision that the respondent casino had been entitled to refuse to pay him winnings of £7.7 million on the basis that he had cheated.

In a card game of chance, Punto Banco, the gambler had used the technique of "edge-sorting", which relied on noting tiny physical differences in the edges of the cards. By claiming to be superstitious, he persuaded the croupier to use the same pack of cards and to turn "lucky" cards around, enabling him to use the technique. That increased his odds of winning. The gambler believed edge-sorting was an honest technique. He sued for his winnings. The judge held that although the gambler was genuinely convinced that what he had done was not cheating, he had in fact and law cheated, thus breaching the implied term against cheating in his contract with the casino.

The gambler argued that the test of what was cheating was the same for the implied term as for the criminal offence of cheating at gambling in the Gambling Act 2005 s.42 and that cheating necessarily involved dishonesty, which had not been demonstrated in his case.


Cheating - The concept of cheating long pre-dated s.42. However, cheating carried the same meaning when considering an implied term not to cheat and when applying s.42. Section 42 did not exhaustively define cheating, and the elaboration in s.42(3) was explanatory rather than definitive. The section left open what was and was not cheating. For the gambler's proposition that cheating necessarily involved dishonesty, he had relied on a discussion of the common law offence of cheating, which had been abolished by the Theft Act 1968. However, there was no reason to suppose that the framers of the 2005 Act had adopted an analogy with an offence abolished 40 years earlier. Although it made sense to interpret the concept of cheating in s.42 in the light of the meaning given to cheating over many years, it made no sense to interpret cheating by reference to dishonesty, an expression introduced into the criminal law for different purposes in 1968. "Cheating", in the context of games and gambling, carried its own inherent stamp of wrongfulness. Although "honest cheating" was an improbable concept, it did not follow either that all cheating ordinarily attracted the description "dishonest" or that anything was added to the legal concept of cheating by an additional legal concept of dishonesty. As an element of a criminal charge, dishonesty was not a defined concept. It was not a matter of law but a jury question of fact and standards. Except to the limited extent that s.2 of the 1968 Act required otherwise, judges must not attempt to define it, R. v Feely (David) [1973] Q.B. 530 applied. Likewise, whether conduct amounted to cheating, given the nature of the game, was a jury question. The addition of the legal element of dishonesty would unnecessarily complicate the question. The judge's conclusion that the gambler's actions amounted to cheating was unassailable. The key factor was the arranging of the cards so that he would know whether the next card was high or low value. He had taken positive steps to fix the deck. In a game which depended on random delivery of unknown cards, that was inevitably cheating (see paras 38-50 of judgment).
