Nguyen, Kathy v R

The appellant, Kathy Nguyen, appealed against her sentence on two grounds after entering guilty pleas to three drug supply offences. The appeal was heard in the High Court of Australia. The primary issue was whether the sentence imposed by the sentencing judge was just and whether there was a marked disparity between the sentences imposed on the appellant and her co-offender. A secondary issue was the appropriate discount for the appellant's guilty plea in comparison to the discount given to her co-offender.

The court examined the principle of parity in sentencing, which requires sentences to be proportionate and justifiable. The court found no error in the sentencing judge's determination of the starting points for the appellant's sentence. However, the court identified a disparity in the discount for the guilty pleas between the appellant and her co-offender. The court concluded that the appellant was entitled to an equivalent discount of 17.5% for her plea of guilty, as her co-offender had received.

The court dismissed the first ground of appeal, finding no error in the starting point of the appellant's sentence. However, the court allowed the second ground of appeal, finding that the disparity in the discount for the guilty pleas was unjust. The court quashed the appellant's sentence and ordered that she be re-sentenced to reflect the appropriate discount of 17.5%. The court emphasised the importance of proportionality and consistency in sentencing to maintain public confidence in the criminal justice system.
