AN IPSWICH woman who tried to run down her former husband and used a knife to stab his new girlfriend is arguing her sentence is too high.
Wimon Seijbel-Chocmingkwan was ordered to serve 10 years' jail, with a serious violent offence declaration requiring her to serve at least 80%, after pleading guilty to attempted murder and dangerous driving.
Barrister Alan MacSporran, acting for Seijbel-Chocmingkwan, said that was manifestly excessive, arguing the Queensland Court of Appeal should reduce it to nine years without the declaration.
He said the court should consider the guilty plea, attempts made before and since arriving in Australia to better herself, her mental illness and lack of pre-meditation.
During the sentencing, the court heard Seijbel-Chocmingkwan "lost the plot" when she saw scenes of her husband's new "happy family" at Redbank Plains while her children were going without.
Crown prosecutor Danny Boyle said the intent to murder might not have been formed before Seijbel-Chocmingkwan arrived at her former husband's house but the sentencing judge found she went over there in a rage.
He said she had a large knife with a 21cm blade and made threats to kill three people which led them to fear for their lives.
"It's not a spur of the moment offence in that she had the time to grab the knife, get out of the car and then pursue the (victim)," he said.
"From the time she went there she was in an aggressive frame of mind and there's no intervening act or event which triggered her conduct other than the argument earlier in the day."
Mr Boyle said the stab wounds from a "persistent and determined" attack and the victim was fortunate to not be killed.
He said Seijbel-Chocmingkwan only stopped when others intervened.
The appeal court reserved its decision.
