Halket v The Queen

The appellant was convicted of two charges of negligently causing serious injury by driving, arising from a collision with a stationary vehicle. The trial judge sentenced the appellant to six years’ imprisonment for the first charge, and four years and six months for the second, to run concurrently, resulting in an effective sentence of seven years and six months. The appellant sought leave to appeal against the sentence, contending it was manifestly excessive. The High Court considered whether the trial judge was constrained by previous sentencing practice and if the sentence was manifestly excessive.

The primary issue before the court was whether the trial judge was constrained by previous sentencing practice in imposing the sentence, and if the sentence was manifestly excessive. The appellant argued that the trial judge was constrained by previous sentencing practice and that the sentence was manifestly excessive, given the appellant's sleep-deprived state and the 'rebound' effect of methylamphetamine at the time of the offence. The Crown argued that the trial judge was not constrained by previous sentencing practice and that the sentence was not manifestly excessive, given the gravity of the offence and the need for general deterrence.

The court held that the trial judge was not constrained by previous sentencing practice and that the sentence was not manifestly excessive. The court found that the trial judge had considered the appellant's sleep-deprived state and the 'rebound' effect of methylamphetamine, but had also considered the gravity of the offence and the need for general deterrence. The court held that the sentence was appropriate and that the appellant had not demonstrated that the sentence was manifestly excessive. The court applied the principles in Harrison v The Queen (2015) 74 MVR 58 and held that the sentence was not manifestly excessive.

The court refused the appellant leave to appeal against the sentence. The court held that the sentence was not manifestly excessive and that the trial judge had properly considered the relevant factors in imposing the sentence. The court found that the sentence was appropriate and that the appellant had not demonstrated that the sentence was manifestly excessive.
