Bull v Australian Quarter Horse Association

The appeal concerned a dispute between Mr Bull and the Australian Quarter Horse Association (the Association) regarding the registration of a cloned horse. Mr Bull sought to register his cloned horse, "Hickory's Ace," with the Association, but his application was refused. The Association relied on its rules and regulations, which Mr Bull contended were improperly interpreted or applied. The matter came before the Court of Appeal of New South Wales.

The central legal issues before the Court of Appeal were whether the Association's Constitution and Regulations, when construed together, entitled Mr Bull to register his cloned horse, and whether the Association had acted in accordance with its own rules. The Court also considered whether the Association's Constitution should be treated as a formal contract between the Association and its members, and the implications of points not having been taken in the court below.

The Court of Appeal affirmed the decision of the primary judge, finding that the Association's rules did not permit the registration of cloned horses. The Court reasoned that the Constitution and Regulations, when read as a whole, established a framework for the registration of horses based on lineage and genetic material, which did not accommodate cloning. The Court also held that the Association was bound by the conduct of its case at trial and that Mr Bull could not raise new arguments on appeal. The Court applied principles of contractual interpretation to the Association's governing documents, treating them as a contract between the Association and its members.

The appeal was dismissed, and Mr Bull was ordered to pay the Association's costs.
