Commonwealth Development Bank of Australia Pty Ltd v Cassegrain

In the case of Commonwealth Development Bank of Australia Pty Ltd v Cassegrain, the dispute arose from a claim by the Commonwealth Development Bank against the defendants, who were the executors of an estate. The nature of the dispute involved the admissibility of an expert report in the proceedings. The matter was heard in the Supreme Court of New South Wales.

The primary legal issue before the court was whether an expert report could be admitted into evidence when the expert witness had failed to acknowledge that they would be bound by the Expert Witness Code of Conduct as required by Part 36 rule 13C(2) of the Supreme Court Rules. The court had to consider the extent to which the failure to acknowledge the binding nature of the Code of Conduct affected the admissibility of the expert's evidence. The defendants argued that the expert's failure to comply with the Code of Conduct rendered the report inadmissible.

The court held that the failure to acknowledge the binding nature of the Expert Witness Code of Conduct did not necessarily disqualify the expert report from being admitted. The court considered that the fundamental purpose of the Expert Witness Code of Conduct was to ensure that expert evidence was reliable and unbiased. The court found that the expert had not acted in a way that was inconsistent with the requirements of the Code of Conduct and that the expert's failure to acknowledge the Code was an oversight rather than a deliberate attempt to disregard it. Consequently, the court made an order permitting the evidence to be admitted, despite the expert's failure to acknowledge the Code of Conduct.

The court's final orders included the admissibility of the expert report, subject to the terms set by the court. The expert's evidence was permitted to be used in the proceedings, with the court taking into account the circumstances surrounding the expert's failure to acknowledge the Code of Conduct. This decision highlights the importance of adherence to procedural requirements while also recognising that technical oversights may not always result in the exclusion of otherwise reliable evidence.
