Brumby v Mt Arthur Coal Pty Ltd; Ready Workforce (A Division of Chandler MacLeod) Pty Ltd v Mt Arthur Coal Pty Ltd

In this matter, Brumby and Ready Workforce, the plaintiffs, brought proceedings against Mt Arthur Coal Pty Ltd, the defendant, in the Federal Circuit Court. The plaintiffs were seeking damages for personal injuries sustained in a workplace incident. The dispute centred around the admissibility of an expert report provided by the plaintiffs' treating chiropractor to the defendant’s solicitor. The report was submitted shortly before the trial, and the defendant sought to tender it as evidence.

The primary legal issue before the court was whether the provision of the expert report to the defendant’s solicitor constituted a waiver of the patient-chiropractor privilege. The court was also required to determine whether the chiropractor could be called to give evidence based on the report. The chiropractor had been subpoenaed to testify, but there was no evidence as to why the defendant did not investigate the matter earlier by subpoena. The court found that the chiropractor’s provision of the report was not an adherence to the legal obligations imposed by the subpoena and did not constitute a waiver of privilege. Consequently, the report was not allowed to be tendered as evidence by the defendant, and the chiropractor could not be called to give evidence based on the report.

The Federal Circuit Court held that the defendant's solicitor’s actions did not result in a waiver of the patient-chiropractor privilege. The chiropractor had been under the mistaken impression that providing the report adhered to the subpoena's legal obligations. The court ruled that the defendant's failure to provide evidence explaining why the subpoena was not used earlier precluded the admissibility of the report and the chiropractor’s testimony. Therefore, the defendant was precluded from using the report as evidence and from calling the chiropractor to testify.
