18. In R v RC (unreported, Supreme Court of the ACT, Burns J, 19 October 2012), the offender stomped on the head of the victim on a number of occasions, causing a large extradural hematoma requiring surgery. This was a potentially life threatening injury. The offence was committed in company. The offender was 29 years old and had an extensive criminal history including numerous matters of violence. He had an extensive history of illicit substance abuse, commencing when he was eight years old. The offender was found not to be remorseful for his actions. Sentence was reduced by approximately 15 per cent to reflect his plea of guilty. He was sentenced to six years' imprisonment reduced from seven years in order to reflect his plea of guilty. A non-parole period of four years and three months was set. I note that this sentence was upheld on appeal. I further note that the maximum penalty for the offence at that time was only 10 years' imprisonment.
