R v JM (Sentence) [2024] NSWSC 1345

R v JM (Sentence) [2024] NSWSC 1345

JM is convicted of manslaughter by excessive self-defence. The offender's moral culpability is substantially reduced by his youth, cognitive impairment, and anxious tendencies. His prospects of rehabilitation are very good, and the sentence must prioritise rehabilitation over deterrence and retribution. The sentence is to be served as a juvenile offender due to his vulnerability and disabilities. No sentence other than full-time imprisonment is appropriate, but special circumstances warrant adjustment to the usual non-parole/total term ratio.
