R v Parker

The case of R v Parker involved a sentencing hearing where Rachel Marie Parker pleaded guilty to manslaughter. The incident stemmed from Parker's involvement in a drug deal that went awry, leading to the murder of Jamie Faulkner by her partner, Jamie Mills. Parker was convicted as a party to the manslaughter, having lured Faulkner to her flat under the guise of completing the drug deal, where Mills subsequently shot Faulkner. Parker did not foresee the killing but recognized that an unlawful killing might result from the plan she and Mills had concocted.

The primary legal issues before the court were determining the appropriate starting point for Parker's sentence and calculating the extent of any mitigating and aggravating factors. The court had to balance Parker's role in the crime, the seriousness of the offence, and her personal circumstances, including her drug addiction and troubled background. The court also needed to consider whether Parker's addiction could be treated as a mitigating factor despite statutory prohibitions.

The court, Miller J, began by selecting a starting point, considering comparable cases and sentencing levels for serious violence. Given the premeditated nature of the crime, the use of a firearm, and Parker's active role, the court determined a starting point of eight years. While Parker's addiction was acknowledged as a mitigating factor, it could not be used to explain her behaviour at the time of the offence due to legislative constraints. The court allowed for a modest discount due to Parker's guilty plea and some allowance for her personal difficulties and remorse. Ultimately, the court imposed a sentence of six years and four months imprisonment, with a minimum non-parole period set at 50% of the sentence, reflecting the gravity of Parker's culpability.
