“Following a three months period of training and implementation the definitive guideline on assault came into effect on 13 June 2011. It aims to ensure a consistent and proportionate approach to sentencing, with convicted offenders receiving a sentence that reflects both the harm they have caused to their victim and their culpability.
This guideline and the updated Magistrates’ Court Sentencing Guidelines, incorporating the new assault guideline, are available here.”
