R v Thomason; ex parte A-G (Qld)

In the case of R v Thomason, the respondent, aged 18 at the time of the incident, attacked a stranger from behind in a public place with a knife, causing the complainant life-threatening injuries. The respondent was intoxicated with alcohol during the attack and continued to harass the complainant post-incident. The respondent subsequently left the scene and did not surrender to the police. He pleaded guilty to grievous bodily harm and was sentenced to four and a half years imprisonment with parole eligibility after 14 and a half months. The Attorney-General of Queensland appealed against the sentence, arguing it was manifestly inadequate and sought the imposition of a serious violent offence declaration.

The legal issues before the court were whether the sentence was manifestly inadequate and whether a serious violent offence declaration should be made despite it not being imposed by the lower court. The court had to consider the principles applicable to appeals by the Crown against sentence and the gravity of the offence, including the nature of the attack, the vulnerability of the victim, the respondent's intoxication, and his failure to surrender. The court needed to determine if the sentence and the absence of a serious violent offence declaration represented a substantial miscarriage of justice.

The court found the sentence to be manifestly inadequate and allowed the appeal. It set aside the original sentence and imposed a six-year imprisonment term, declared the respondent convicted of a serious violent offence, and declared that 71 days spent in pre-sentence custody between 1 July 2010 and 9 September 2010 was time already served under the sentence. The court considered the attack to be of extreme gravity, the respondent's intoxication and subsequent actions exacerbating the severity of the crime, and the need for the sentence to reflect the seriousness of the offence and deter similar conduct in the future.
