Balnaves, C.J. and Balnaves, P.J.; Cummings, J.T. (Intervener).

The Full Court of the Supreme Court of Western Australia heard an appeal concerning a dispute between the appellants, Balnaves, C.J. and Balnaves, P.J., and the intervener, Cummings, J.T. The precise nature of the dispute is not detailed in the provided text, but it involved a legal matter that led to an appeal before this appellate court.

The court was required to determine the legal issues arising from the dispute between the parties. While the specific issues are not elaborated upon, the context of an appeal suggests that the court's task was to review a prior decision or ruling and consider the legal arguments presented by the appellants and the intervener.

The judgment was delivered by Nicholson C.J., Fogarty J., and McCall J. Their reasoning and the legal principles applied would have been based on their interpretation of relevant Australian law as it pertained to the facts of the case. The outcome of the appeal, including any orders made by the court, is not provided in the excerpt.
