Mulvihill v R

In the case of Mulvihill v R, the applicant, who was convicted of murder, sought leave to appeal against both his conviction and sentence. The applicant argued that he did not intentionally inflict the fatal knife wounds on the deceased, but rather that the wounds were sustained accidentally during a struggle. The applicant also contended that the trial judge had erred in several respects, including by not leaving the options of unlawful and dangerous act manslaughter or the "second limb" of self-defence to the jury, not allowing the jury to consider provocation, and giving certain directions on circumstantial evidence, flight as consciousness of guilt, and the onus and standard of proof. Additionally, the applicant claimed that prejudicial comments and a breach of the rule in Browne v Dunn by the prosecutor caused the trial to miscarry. The High Court granted leave to appeal on two grounds, but ultimately dismissed the appeal against conviction.

The appeal against sentence raised issues regarding the judge's failure to take into account the applicant's facilitation of the administration of justice, the judge's permitting and taking into account evidence of the applicant's alleged prior misconduct, and the judge's not taking into account the applicant's mental illness. The High Court granted leave to appeal against the sentence but ultimately dismissed the appeal.

The High Court found that the trial judge did not err in failing to leave the options of unlawful and dangerous act manslaughter or the "second limb" of self-defence to the jury, as the applicant did not conduct his case on either of those bases. The Court also found that the judge's directions on circumstantial evidence, flight as consciousness of guilt, and the onus and standard of proof did not contain any errors that would warrant a new trial. Furthermore, the Court found that there were no prejudicial comments or breaches of the rule in Browne v Dunn that would have caused the trial to miscarry. The Court held that the trial judge did not err in permitting and taking into account evidence of the applicant's alleged prior misconduct, and that there was no error in the judge not taking into account the applicant's mental illness as a mitigating factor in sentencing.
