Fysh v The Queen

The appellant, Fysh, appealed against his convictions for two counts of insider trading, arguing that the verdicts were unreasonable in light of the evidence presented. The appeal was heard by the High Court of Australia, which was required to determine several legal issues, including whether the Crown had adequately proven that the appellant possessed each item of information alleged, whether the information was material, and if the limitations in the Crown's expert evidence were significant enough to affect the outcome. Additionally, the court had to decide whether the Crown had proven beyond reasonable doubt that the appellant possessed the critical information on the relevant date and whether the information that was not proven by the Crown "made no real difference." The court found that the factual basis for the Crown's case was not established, leading to the conclusion that the convictions were unreasonable. Consequently, the convictions were quashed, and a verdict of acquittal was entered in their place.
