Ivey v Genting Casinos (UK) Ltd t/a Crockfords [2017] UKSC 67
Facts
Professional gambler Phil Ivey used an edge-sorting technique while playing a card game at Crockfords casino. Small differences on the backs of cards could reveal information about their values. He and an associate induced the croupier to handle particular cards in ways that made the technique effective, without explaining the real reason for their requests. After substantial winnings accumulated, the casino refused payment. Ivey brought a civil claim, maintaining that his method was legitimate advantage play. The dispute reached the Supreme Court on the meaning of cheating and its relationship with dishonesty.
Legal Issue
Did Ivey's manipulation of the game amount to cheating despite his belief that it was legitimate, and was the subjective second stage of the Ghosh dishonesty test a correct statement of law?
Held
The Supreme Court dismissed Ivey's appeal. His actions interfered with the process of the game and amounted to cheating; an additional finding of dishonesty was not necessary to resolve that issue. The court nevertheless examined dishonesty and rejected the second limb of R v Ghosh. It explained that the fact-finder first establishes the person's actual knowledge or belief about the facts and then assesses the conduct by the standards of ordinary decent people. The person need not recognise that those standards condemn the conduct. The dishonesty discussion was not necessary to the cheating conclusion, an important distinction when describing the decision's authority.
⭐ Legal Principle
Dishonesty is assessed by establishing the individual's actual knowledge or belief about the facts and then applying the standards of ordinary decent people. It is unnecessary for the individual to appreciate that others would regard the conduct as dishonest; factual belief remains relevant.
Significance
Although arising from a civil gambling dispute, the judgment reshaped the teaching of dishonesty across criminal and civil law. Its discussion was subsequently adopted for criminal cases in R v Barton and Booth [2020] EWCA Crim 575. Students should distinguish the historical status of the Supreme Court's observations from that later criminal adoption. They should also avoid describing the test as wholly objective: the defendant's actual understanding of the facts is established before the objective evaluation.
Common exam questions about this case
Is Ivey a criminal conviction for cheating?
No. It concerned a civil claim to recover casino winnings. The Supreme Court rejected the claim because the conduct amounted to cheating. Its influential discussion of dishonesty arose within that civil appeal, and should not be retold as a prosecution or conviction for theft.
Which part of Ghosh did the Supreme Court reject?
It rejected the additional requirement that the defendant must realise ordinary people would consider the conduct dishonest. Actual knowledge or belief about the facts remains relevant. Once that factual perspective is established, the conduct is evaluated by ordinary decent people's standards, without adopting the defendant's personal moral standards.
How should an answer explain ratio and obiter here?
The cheating conclusion disposed of Ivey's claim without requiring an additional dishonesty finding. The wider reformulation of dishonesty was therefore an influential discussion beyond what was necessary for that outcome. Its later adoption in Barton and Booth explains why it governs criminal dishonesty analysis despite that original procedural setting.
