Ivey v Genting Casinos

is a UK Supreme Court case that reconsidered the test used for determining dishonesty.

Facts
Phil Ivey, an American professional poker player, played and won a series of games of Punto Banco—a variant of baccarat—at Crockfords Casino in London, owned by Genting Casinos (UK) Ltd. The casino did not pay out the £7.7m he had won, as they believed Ivey had cheated by using edge sorting. Ivey sued the casino to recover his winnings.

Both Ivey and the casino agreed that the contract contained an implied term forbidding cheating. Ivey's lawyers argued that the appropriate test for whether cheating occurred was the same for contract as it was in section 42 of the Gambling Act 2005, and that cheating necessitated dishonesty, which had not been shown.

At trial, High Court Judge John Mitting held that cheating had occurred and the contract was thus invalid. The Court of Appeal upheld the trial judge's ruling 2–1.

Decision
The Supreme Court held that Ivey was not entitled to the payment sought from Genting Casinos because he was dishonest.

Reception
In the High Court case of DPP v Patterson, Sir Brian Leveson observed that:

"Given the terms of the unanimous observations of the Supreme Court expressed by Lord Hughes, who does not shy from asserting that Ghosh does not correctly represent the law, it is difficult to imagine the Court of Appeal preferring Ghosh to Ivey in the future."

The applicability of the Supreme Court's direction in Ivey to criminal law was affirmed by the Court of Appeal (Criminal Division) in R v Booth and Barton.

David Ormerod and Karl Laird criticised the direction of the law following Ivey, arguing that the lack of a subjective element will lead to uncertainty and a possible human rights challenge under Article 7, citing a prior challenge to Ghosh.
