Canon Finance Australia Limited v Reliance Medical Practice Pty Ltd (No 2)

In the Federal Court of Australia, Canon Finance Australia Limited sought a judgment against Reliance Medical Practice Pty Ltd for an outstanding debt. The matter involved a dispute over the admissibility and relevance of expert evidence presented by the defendant in their defense against the claim. The primary legal issue was whether the opinions expressed by the defendant's expert were based on the expert's specialised knowledge, training, education, and experience, or if they were merely a bare expression of opinion without sufficient basis in expertise.

The court considered the principles established in the case of Cooper v The Commonwealth of Australia, where it was held that expert evidence must be founded on the expert's specialised knowledge and not merely a lay opinion. The court scrutinised the expert's qualifications and the basis of their opinions to determine if they met the threshold for admissibility. The court found that the expert's opinions lacked a sufficient foundation in their specialised knowledge and were not wholly or substantially based on their expertise, training, education, and experience. Consequently, the court ruled that the evidence was inadmissible and could not be considered in the proceedings.

As a result of the inadmissible evidence, the court was able to proceed with the claim without the need to consider the defendant's expert evidence. The court found in favour of the plaintiff, Canon Finance Australia Limited, and ordered Reliance Medical Practice Pty Ltd to pay the outstanding debt plus interest. The court's decision highlights the importance of ensuring that expert evidence is grounded in the relevant expertise of the witness to be deemed admissible in legal proceedings.
