R v Murch; R v Logan

In *R v Murch; R v Logan*, the Court of Appeal of Victoria considered appeals against convictions for attempted murder. The two appellants, Murch and Logan, were jointly tried. The prosecution's case relied heavily on the evidence of an accomplice, Richards. Murch contended that the trial judge erred by refusing to allow him to cross-examine his co-accused, Logan, about alleged collusion between Logan and Richards. Both appellants also argued that the trial judge made errors in his directions to the jury regarding the corroboration of the accomplice's evidence.

The primary legal issues before the Court of Appeal were whether the trial judge wrongly prevented Murch from cross-examining Logan on matters relevant to potential collusion, and whether the directions given to the jury concerning the corroboration of the accomplice Richards' evidence were inadequate and confusing. The Court also considered other grounds of appeal, including issues relating to legal professional privilege and the adequacy of directions on self-defence and the onus of proof, but these were not ultimately determinative of the outcome.

The Court held that the trial judge erred in refusing to allow Murch to cross-examine Logan. The proposed questioning was deemed relevant as it had the potential to elicit material that could undermine the credibility of both Logan and Richards, and consequently weaken the prosecution's case against Murch. The Court found that the judge incorrectly classified certain items of evidence as corroborative when they were not, and that the directions on corroboration were confusing and failed to adequately address the evidence in relation to each appellant separately. This, the Court concluded, robbed the corroboration warning of its intended force.

Consequently, the Court allowed the appeals on the grounds relating to the corroboration directions and Murch's ground concerning the admissibility of cross-examination. Finding no room for the application of the proviso, the Court quashed both convictions and directed a retrial for each appellant.
