Jason Mammoliti v The Queen

Jason Mammoliti appealed against his conviction for aggravated carjacking, seeking to overturn the six-year sentence with a non-parole period of four years imposed by the County Court. The case was heard by the Court of Appeal, which had to determine whether the sentence was manifestly excessive given the statutory maximum penalty of 25 years and a mandatory minimum non-parole period of three years. The appeal hinged on whether it was reasonably open to the judge to impose the given sentence, considering the nature of the crime and the offender's history.

The court needed to assess the balance between the judge's sentencing discretion and the statutory minimum non-parole period. The appellant argued that the sentence was manifestly excessive due to the mandatory minimum and the disparity between the actual and maximum penalties. The court considered the principles of proportionality and the impact of the crime on the vulnerable victim. Additionally, the offender's criminal history and the fact that the offence occurred while on a community correction order were crucial factors in the sentencing process.

The Court of Appeal held that it was reasonably open to the trial judge to impose the sentence in question. While the mandatory minimum non-parole period influenced the decision, the court found that the sentence was not manifestly excessive. The judge had considered the principles of proportionality, the offender's history, and the impact on the victim. The limited comparable cases did not establish a clear benchmark, but the sentence fell within the range of what could be considered appropriate. Consequently, the appeal was dismissed, but leave to appeal was granted. The sentence remained upheld as not manifestly excessive.
