R v Jon Stephen McKENZIE [2011] NSWSC 1460

R v Jon Stephen McKENZIE [2011] NSWSC 1460

The appropriate sentence for Jon Stephen McKenzie was determined after applying a 25% utilitarian discount to a head sentence of 19 years for the murder of his wife. Special circumstances justified a reduced non-parole period ratio, resulting in a total sentence of 14 years, 3 months with a 10-year non-parole period. The court took account of McKenzie's age, mental illness linked to a physical condition, lack of prior offending, remorse, acceptance of responsibility, and the circumstances of the offence which, while unpremeditated, involved violence and resulted in the loss of life.
