R v Pratten (No 20)

The case of R v Pratten (No 20) involved the defendant, Pratten, who was on trial for criminal charges related to his financial dealings. The dispute centred on whether the Crown had fundamentally altered its case during the trial, leading to the potential discharge of the jury. This case was heard in the High Court of Australia, which is the highest court in the Australian judicial system and has the final say on legal matters.

The primary legal issue before the court was whether the Crown's case had fundamentally changed in a way that would necessitate the discharge of the jury. The court needed to determine if the Crown's case was limited to the proposition that Pratten's income was exclusively derived from the Vanuatu Insurance Company or if it encompassed other sources of income, such as loans. The court also had to assess whether the evidence of loans presented by the Crown was sufficient to undermine the defendant's evidence that his income was not consistent with the Crown's case.

The High Court found that the Crown's case had indeed fundamentally changed during the trial. The court held that the Crown's case was not confined to the proposition that Pratten's income was exclusively from the Vanuatu Insurance Company but had expanded to include evidence of loans. This change in the Crown's case was significant enough to warrant the discharge of the jury. The court determined that the evidence of loans adduced by the Crown was sufficient to undermine Pratten's evidence that his income was not consistent with the Crown's case, leading to the conclusion that the jury should have been discharged.

The final outcome of the case was that the High Court granted the defendant's application to discharge the jury due to the fundamental change in the Crown's case. The court's decision underscored the importance of maintaining the integrity of the trial process and ensuring that any significant changes to the prosecution's case are appropriately addressed. The court's ruling in this case provides guidance for future trials involving similar issues, emphasising the need for clarity and consistency in the presentation of the Crown's case.
