R v Trevenna

In R v Trevenna, the respondent appealed against her sentence for manslaughter, while the Crown sought to increase it. The respondent argued that her sentence was manifestly excessive and disproportionate compared to similar cases. The Crown sought to argue that the sentence should be increased, contending that it was too lenient given the nature of the offence. The court needed to determine whether the sentence was manifestly inadequate and whether the Crown’s appeal to increase it was justified. The court also had to consider the range of sentences for similar offences to determine if the respondent's sentence was appropriate.

The court considered the respondent’s plea of manslaughter under s421 of the Crimes Act, which deals with self-defence where excessive force results in death. The court acknowledged the circumstances under which the respondent acted, including her perception of an imminent threat to her life and the threat to her son. The court balanced these mitigating factors against the objective seriousness of the offence, concluding that while the respondent’s actions were excessive, the perceived imminent danger she faced contributed to the circumstances. The court also noted the significant discount given for the plea of guilty and the expression of remorse. In light of these factors, the court found the original sentence to be excessive and reduced it accordingly. The court dismissed the Crown’s appeal, finding that any increase in sentence would be unwarranted given the appropriate range for this type of offence.

The court reduced the head sentence from seven and a half years to six years and six months, and the non-parole period from four and a half years to four years. The court concluded that the reduced sentence was more appropriate given the circumstances of the case and the principles of sentencing. The Crown’s appeal to increase the sentence was dismissed as it would not be justified by any conceivable range of sentences for the offence. The respondent’s appeal against the sentence was allowed, with the modifications to the sentence as outlined.
