Legal Principles
Sentencing for manslaughter due to diminished responsibility involves assessing the level of responsibility retained and placing it within the appropriate guideline range.
Sentencing Guidelines
Section 285 of the Sentencing Act 2020 allows for life sentences if the offender is considered dangerous.
Sentencing Act 2020, s. 285
Determining dangerousness requires consideration of previous offences, pattern of behavior, and risk of future harm.
Sentencing Act 2020, s. 308
The seriousness of an offense to justify a life sentence depends on the offense itself, previous convictions, danger to the public, and available alternative sentences.
