R v Sione; R v Dawson [2024] NSWSC 846

R v Sione; R v Dawson [2024] NSWSC 846

Richard Sione’s culpability for murder was not so extreme as to justify a life sentence: severe violence and leadership in the criminal enterprise warranted a severe, but determinate term. Kayla Dawson’s cognitive impairment and psychological immaturity substantially reduced her moral culpability, justifying a sentence below the standard non-parole period and finding of special circumstances.
