R v Oliver [2024] NSWSC 1571

R v Oliver [2024] NSWSC 1571

The offender’s moral culpability for manslaughter is reduced to a limited extent due to evidence of compromised psychosocial maturity and consequential thinking, traceable to childhood trauma and deprivation, but not a comprehensive causal connection. An aggregate sentence of imprisonment is imposed, taking account of objective and subjective factors, aggravating circumstances, and special circumstances based on the need for extended supervision and the more onerous impact of incarceration due to PTSD.
