Kaplan v State of Victoria (No 3)

In the case of Kaplan v State of Victoria (No 3), the dispute primarily involved the admissibility of an expert report tendered during the proceedings. The matter was heard in the Federal Court of Australia, with Kaplan as the plaintiff and the State of Victoria as the defendant. The crux of the dispute was whether the expert report, authored by Stephen Paul, could be admitted into evidence given the manner in which the expert was instructed and the subsequent conclusions drawn.

The court was tasked with determining whether the expert's report could be admitted into evidence, especially considering the nature of the instructions provided to the expert. A significant issue was whether the expert was given specific factual assumptions upon which to base his report or if he was merely provided with witness outlines. The court had to evaluate whether the lack of specific factual assumptions led to the expert expressing conclusions on matters of material fact, which in turn rendered the report inadmissible.

In reaching its decision, the court considered the method by which the expert was instructed and the resultant conclusions. It was determined that the expert was not provided with specific factual assumptions, which is a crucial component in ensuring that an expert's opinion is based on a sound factual foundation. As the expert's report contained conclusions on material facts without the benefit of specific factual assumptions, the court found that the expert report could not be admitted. Consequently, the tender of the expert reports dated 8 May 2022 and 17 June 2022 was rejected.

The court's final order, in accordance with Rule 39.32 of the Federal Court Rules 2011, was to reject the tender of the expert reports of Stephen Paul dated 8 May 2022 and 17 June 2022. This decision underscores the importance of proper instruction to experts to ensure the admissibility of their reports in legal proceedings.
