Winslade Partners Pty Ltd v Steri-Flow Filtration Systems (Aust) Pty Ltd

Winslade Partners Pty Ltd (the appellant) appealed a decision of a single judge of the Supreme Court of South Australia, which upheld a Magistrate's finding in favour of Steri-Flow Filtration Systems (Aust) Pty Ltd (the respondent). The dispute arose from a contract where the appellant agreed to prepare a grant application for the respondent on a success fee basis. The application was unsuccessful, but the respondent later obtained a similar grant through another company. The appellant then claimed a success fee based on the original agreement.

The Full Court was required to determine several legal issues. These included whether a claim based on copyright could be raised for the first time on appeal, and whether the single judge erred in allowing the appellant to advance a quantum meruit claim that had not been considered by the Magistrate. The court also had to consider whether the evidence established that the respondent had benefited from the appellant's work on the initial application, and whether the respondent had been unjustly enriched. Finally, the court considered whether the single judge had erred in implying a term that the work done by the appellant became the property of the respondent, despite this not being pleaded or argued at trial.

The Court held that it was too late to raise a claim based on copyright, as this had not been pursued at trial or before the single judge, and the claim was abandoned during the appeal hearing. The quantum meruit claim was also abandoned at trial. The Court found that the contract had not failed or been frustrated, and the case did not fall under the principles of restitution for unjust enrichment as articulated in *Roxborough v Rothmans of Pall Mall Australia Ltd*. Crucially, there was insufficient evidence to establish the extent to which the respondent had made use of or benefited from the appellant's work. The Court also noted that the contractual arrangements were inconsistent with the grant of relief sought by the appellant, rendering it unnecessary to definitively decide whether the single judge had erred in implying a term regarding ownership of the work.

Consequently, the appeal was dismissed.
