Application by Duong Hai Nguyen pursuant to s78 Crimes (Appeal and Review) Act 2001

Duong Hai Nguyen applied for an inquiry into his sentence under section 78 of the Crimes (Appeal and Review) Act 2001, challenging whether there was doubt or question as to a mitigating circumstance and whether his sentencing was affected by the Muldrock error. Nguyen was convicted of murder and maliciously inflicting grievous bodily harm after a trial. His sentence was subsequently reduced following a successful appeal to the Court of Criminal Appeal. The central issue before the court was whether there existed doubt or question about a mitigating circumstance and if the sentencing was influenced by the Muldrock error, which relates to the Court of Criminal Appeal’s approach to sentence review.

The court examined whether the Court of Criminal Appeal had engaged in the two-stage process or given determinative significance to the standard non-parole period, as prescribed by Muldrock. The court concluded that the Court of Criminal Appeal did not follow the two-stage process or assign determinative significance to the standard non-parole period. Consequently, the application for an inquiry into the sentence was refused. The court held that no doubt or question existed regarding the mitigating circumstances, and the sentencing was not impacted by the Muldrock error.

The final orders of the court were that the application for an inquiry into the sentence was dismissed. The sentence imposed by the Court of Criminal Appeal remained unaltered, and no further review of the sentence was warranted under section 78 of the Crimes (Appeal and Review) Act 2001.
