Lym International Pty Ltd v Chen; Marcolongo v Lym International Pty Ltd

In Lym International Pty Ltd v Chen and Marcolongo v Lym International Pty Ltd, the Federal Court of Australia was tasked with determining the admissibility of expert opinion evidence presented in proceedings involving disputes over a commercial transaction. The parties involved were Lym International Pty Ltd, Chen, and Marcolongo, with the dispute centring on the validity and admissibility of expert reports submitted by the parties, particularly in relation to their compliance with statutory and procedural requirements for expert evidence.

The court was required to decide whether the expert evidence submitted by the parties was admissible. This involved an examination of the expert reports to determine whether they contained the facts and assumptions of fact on which the opinions were based, as well as whether the qualifications of the expert witnesses were sufficient. Additionally, the court had to assess whether the experts had complied with the expert witness code of conduct, particularly in the context of the very late compliance with the requirements for admissibility.

The court found that the expert evidence was inadmissible due to significant deficiencies in the reports. The experts failed to include the facts and assumptions of fact on which their opinions were based, and their qualifications did not meet the necessary standards. Furthermore, the experts did not comply with the expert witness code of conduct, and their compliance with the statutory requirements for admissibility was very late. Consequently, the court held that the expert evidence was not admissible, which had a material impact on the proceedings. The court's decision underscored the importance of strict adherence to the statutory and procedural requirements for expert evidence to ensure the integrity of the judicial process.
