R v Oncu; R v Dogan; R v Unver; R v Bassi-Anstee

The four appellants, each facing drug manufacturing and supply charges, as well as firearm offences, appealed against their sentences imposed by the Supreme Court of New South Wales. The appeal raised issues about the differing roles of each offender within a large-scale drug manufacturing operation, the extent of their criminal involvement, and the appropriate sentences. The court considered whether the sentences were manifestly excessive or inadequate in light of the crimes committed.

The key legal issues included the assessment of the appellants' roles within the drug manufacturing operation, the consideration of the large commercial quantity of methylamphetamine manufactured and supplied, the possession of an unauthorised pistol, and the implications of police surveillance on the operation. Additionally, the court had to determine if any of the appellants could be considered a "boss" of the operation and whether the sentences imposed were proportionate to the crimes.

In considering the appeal, the court noted that although no offender was a "boss" of the operation, each played a significant role in the substantial drug manufacturing operation. The operation was housed in a purpose-built shed, and the appellants were exposed to the risk of detection and arrest. The court found that the sentences were not manifestly excessive or inadequate, taking into account the individual roles and the severity of the crimes committed. The court dismissed the appeals, upholding the sentences imposed by the trial judge.

The court confirmed the sentences as follows: Mr Oncu is sentenced to an aggregate term of imprisonment of 9½ years with a non-parole period of 6½ years. Mr Dogan and Mr Unver each received a sentence consisting of a non-parole period of 4½ years and a head sentence of 7½ years. Lastly, Mr Bassi-Anstee was sentenced to imprisonment consisting of a non-parole period of 6 years and a head sentence of 9 years. The appeals were dismissed, and the original sentences were upheld.
