Murillo (a pseudonym) v The Queen

The case of Murillo v The Queen involved an applicant, referred to as Murillo, who was convicted of five counts of indecent assault and three counts of incest. Murillo sought to appeal against his conviction, challenging the trial judge's decisions to admit misconduct evidence and grant leave for the prosecutor to cross-examine a witness under section 38 of the Evidence Act 2008. The crux of the appeal was whether the trial judge had erred in these decisions, which Murillo argued led to a substantial miscarriage of justice and a breach of the duty of fairness.

The legal issues before the court were whether the trial judge correctly exercised their discretion in admitting the misconduct evidence and granting leave for the prosecutor to cross-examine the witness. Murillo argued that the misconduct evidence was not relevant and its prejudicial effect substantially outweighed any probative value. Additionally, Murillo contended that the cross-examination under section 38 exceeded its intended scope, as the prosecutor used inflammatory language that was not confined to the matters allowed by the section. The court had to determine whether these actions by the trial judge amounted to an error in law that warranted an appeal.

The court found that the trial judge had indeed erred in admitting the misconduct evidence and in granting leave for the cross-examination under section 38. The misconduct evidence was deemed irrelevant and its prejudicial impact significant, thus improperly influencing the jury. Furthermore, the prosecutor's cross-examination went beyond the permissible scope under section 38, employing language that was inflammatory and prejudicial. These errors were considered serious enough to constitute a substantial miscarriage of justice and a breach of the duty of fairness. The appeal was allowed, and the conviction was quashed, reflecting the significant impact of these errors on the trial's fairness.

The final orders of the court involved quashing Murillo's conviction and ordering a retrial. The court's decision highlighted the importance of adhering to statutory provisions and judicial discretion in maintaining a fair trial, particularly in the context of evidence admissibility and witness cross-examination.
