Re Earlturn Pty Ltd

In the case of Re Earlturn Pty Ltd, the primary focus was on the admissibility of expert evidence tendered by a forensic accountant in the context of a dispute before the court. The court was tasked with determining whether certain portions of an affidavit provided by John Goggin, a forensic accountant, could be admitted into evidence, particularly those sections that relied on data authored by others. The reliance on these data sources raised questions about whether the expert’s opinion was based on inadmissible hearsay evidence. Additionally, the court considered whether the data sources were within the accountant's field of expertise and whether their habitual use in the profession had established their accuracy and trustworthiness.

The legal issues that the court had to resolve centred on the principles of expert evidence admissibility. Specifically, the court needed to determine if an expert could rely on hearsay data to form their opinion and whether such reliance would render the expert’s opinion based on inadmissible evidence. The court also had to assess whether the data sources in question were within the expert’s area of expertise and whether the profession had tested and sanctioned their accuracy and trustworthiness.

The court concluded that certain sections of the affidavit were not admissible as they relied on data that constituted hearsay and was not within the expert’s field of expertise. The court found that the expert's reliance on these data sources did not meet the necessary criteria for admissibility under the rules of evidence. As a result, specific paragraphs of the affidavit were struck out. This decision underscored the importance of the foundational reliability and relevance of data used by experts in forming their opinions, particularly in the context of admissibility in court proceedings.

The court’s final orders included striking out paragraphs 7.13 to 7.17 inclusive, and 8.6 of the affidavit provided by John Goggin, the forensic accountant. These sections were deemed inadmissible due to their reliance on hearsay evidence and the lack of expertise regarding the data sources used.
