Sentence of girl, 16, who stabbed three men reduced by SA court in time for Christmas A teenage girl has had her sentence for stabbing three men in Gawler reduced on appeal. The altercation occurred outside The Exchange Hotel, Gawler. Dutch fatal assault victim Henk van Oosterom was killed when punched while trying to break up a fight outside a Gawler pub in early September 2012. He is pictured with his 18-month-old daughter Janice and partner Sandra van der Klink.

AN AGGRESSIVE teenage girl who stabbed three men outside a Gawler hotel during a month of pub violence around SA has received a shortened sentence at Christmas. In a unanimous decision, the Full Court of the Supreme Court has ordered the girl's 20 months of detention be reduced to 12 months - meaning she will be released in June. In August 2012 the 16-year-old - who admitted carrying a knife "for protection" - stabbed one man in the stomach, one in the knee and slashed a third on the hand outside the Exchange Hotel, Gawler . The incident occurred just two weeks after Christopher Hatzis was fatally stabbed - allegedly by a group of five people - outside the Savvy nightclub on Light Square, Adelaide . A fortnight later, Dutch national Henk van Oosterom was killed by a single punch in the carpark of the Bushman Hotel, Gawler . The crimes prompted Gawler publicans to call for stricter licencing measures ahead of the State Government's controversial 3am liquor lockout . Originally charged with attempted murder, the girl pleaded guilty to aggravated counts of intentionally causing serious harm, intentionally causing harm and assault causing harm. In June this year, the Youth Court imposed a sentence of 20 months' detention, reduced from 24 months due to the teenager's plea, contrition and remorse. The girl challenged that term in the Full Court, arguing it was manifestly excessive and failed to obey the requirements of the Young Offenders Act (1993). That legislation says courts must impose sentences that encourage rehabilitation and send youths to jail only as a last resort. In a judgment published on Christmas Eve, Justices Tom Gray, Tim Anderson and Malcolm Blue said CCTV footage of the incident showed the girl's "aggressive" behaviour. Justice Gray said the girl lunged at the men, chasing and kicking them before "rushing" at one and stabbing him in the stomach. She stabbed her second victim in the knee - and again when he tried to defend himself - then cut the hand of the third victim as he tried to restrain her "with a bear hug." "The defendant said she carried a knife for self-protection (because) she had been sexually assaulted some years earlier," Justice Gray said. It appears she considered that the police did not properly address the complaint (and) did not feel safe 'knowing the cops didn't do anything'. Justice Gray said the first victim's stomach wound was life-threatening, while the other men suffered permanent scarring and disfigurement. He said that, while the girl had no prior criminal history, she had a troubled childhood, past substance abuse problems and "high anxiety" due to the sexual assault. However, pre-sentence reports showed she had a supportive family, had engaged in education while in custody and was becoming a "polite, resilient, self-motivated" young woman. Justice Gray said the Youth Court had failed to give adequate weight to the girl's rehabilitation and her "good prospects to return to the community as a law-abiding and contributing citizen." He, Justice Anderson and Justice Blue set aside the girl's original sentence and replaced it with a 12-month term, backdated to June.
