A v New South Wales

This case concerned an appeal to the High Court of Australia by an applicant, A, against the State of New South Wales and a Detective Constable Floros. The dispute arose from a claim of malicious prosecution following the applicant's acquittal of charges laid against him. The primary judge had found in favour of the applicant regarding one charge but not the other, awarding damages. However, the Court of Appeal had reversed this finding, leading to the present appeal.

The High Court was required to determine whether the prosecutor, Detective Constable Floros, acted without reasonable and probable cause and whether he acted maliciously in laying and maintaining the prosecution against the applicant. Specifically, the court considered whether the prosecutor honestly formed the view that there was a proper case for prosecution or whether this view was based on an insufficient foundation, and whether the sole or dominant purpose of the prosecutor was other than the proper invocation of the criminal law.

The High Court's reasoning focused on the findings of the primary judge, Cooper DCJ, who had found that Detective Constable Floros acted maliciously. The primary judge inferred this malice from statements made by Detective Constable Floros to a Mr Walsh, which suggested that the charges were laid not to bring a wrongdoer to justice, but to succumb to pressure from the Child Protection Enforcement Agency due to the applicant's employment within the Police Service. The primary judge found that the prosecutor had acted with an improper purpose. The Court of Appeal had reversed this finding of malice, but the High Court considered the primary judge's interpretation of the evidence to be open and permissible.

The High Court allowed the appeal in part. It varied the orders of the Court of Appeal to include costs for the applicant in relation to the appeal to the Court of Appeal. It also set aside other paragraphs of the Court of Appeal's orders and substituted an order dismissing the cross-appeal with costs. Finally, the respondents were ordered to pay the appellant's costs of the appeal to the High Court.
