Obian v The King

The High Court of Australia considered an appeal by the appellant, Obian, against his conviction for trafficking in a drug of dependence. The dispute arose from the trial judge's decision to grant the prosecution leave to adduce evidence in reply, pursuant to section 233(2) of the *Criminal Procedure Act 2009* (Vic). The prosecution's case alleged the appellant hired a van used in the transportation of drugs. The appellant testified that he hired the van on behalf of a friend and had no further involvement with it.

The central legal issues before the High Court were whether the trial judge erred in granting leave for the prosecution to adduce evidence in reply, and whether this decision involved a substantial miscarriage of justice. This question turned on whether the appellant's evidence could have reasonably been foreseen by the prosecution, given the appellant's prior responses to the prosecution's opening and notice of pre-trial admissions. The Court also considered the proper construction of section 233(2) of the *Criminal Procedure Act 2009* (Vic), specifically whether the trial judge was limited to considering only the two specified documents or could have regard to other relevant material.

The High Court reasoned that the construction of section 233(2) should permit the trial judge to consider the two specified documents and any other relevant material to accurately determine if the accused's evidence was reasonably foreseeable. This approach aligns with the statutory objective of encouraging compliance with pre-trial procedures and ensuring the power to admit reply evidence is exercised on a proper factual basis. The Court found that the appellant's evidence, that he hired the van for a friend and had no further involvement, was not reasonably foreseeable by the prosecution, particularly in light of the prosecution's understanding of the appellant's prior admissions.

Consequently, the High Court concluded that the majority in the Court of Appeal were correct in finding that the trial judge did not err in exercising the power under section 233(2) of the *Criminal Procedure Act 2009* (Vic). The appeal was therefore dismissed.
