Australian Securities and Investments Commission v Rich

The Australian Securities and Investments Commission (ASIC) appealed a ruling by Austin J in the Supreme Court of New South Wales concerning the admissibility of an expert report prepared by Mr. Carter. The central dispute revolved around whether Mr. Carter's expert opinion evidence, contained within the "Carter Report," was admissible under sections 76 and 79 of the *Evidence Act 1995* (Cth) and whether the trial judge had erred in exercising his discretion under section 135 of the same Act to exclude it.

The primary legal issues before the Court of Appeal were whether the Carter Report met the requirements for admissibility of expert evidence, particularly concerning the disclosure of the facts and reasoning upon which the expert's opinions were based. This included whether it was sufficient for admissibility that the report disclosed the facts and reasons asserted as the basis for the opinion, even if those were not the basis upon which the opinion was first formed. Furthermore, the court had to consider whether the trial judge's failure to analyse the probative value of the evidence constituted a fundamental error in the exercise of his discretion under section 135 of the *Evidence Act 1995*.

The Court of Appeal allowed the appeal, finding that the trial judge had erred in his ruling. The court held that the disclosure requirements under section 79 of the *Evidence Act 1995* are satisfied if the expert report sets out the facts and reasoning that the expert asserts as the basis for their opinion, regardless of whether those were the initial grounds for forming the opinion. The court also determined that the trial judge had made a fundamental error by failing to undertake the necessary analysis of the probative value of the Carter Report before exercising his discretion under section 135 to exclude it. Consequently, the court set aside the ruling that the Carter Report was inadmissible or should be excluded.
