Ousted WA cop wins speeding 'lies' appeal A former WA cop has had a conviction for perverting the course of justice over a minor speeding fine overturned on appeal. A FORMER Perth police officer who quit the force after admitting trying to cover up a speeding offence while on duty has had her conviction quashed by Western Australia's Court of Appeal. Kim Rainier pleaded guilty to perverting the course of justice and was fined $300 in 2011, after she admitted making false notes to cover up breaking the speed limit by 12 km/h. Ms Rainier had been caught by a speed camera driving at 72km/h in a 60 km/h zone without authority, in 2010. She resigned from the force when the Police Commissioner expressed no confidence in her. At the 2011 court case, Perth's District Court Judge John Staude said he felt Rainier had been treated unfairly. With the backing of the WA police union, Ms Rainier launched an appeal against the conviction on the grounds the conduct ``was not an offence known to the law," even though she had pleaded guilty. Although the case had gone to court, Ms Rainier had only falsified the notes to avoid a fine, the Court of Appeal was told. Ms Rainier's lawyers argued that because she only expected to be given a speeding fine and not to be taken to court, the false statements could not be categorised as an attempt to pervert the course of justice. Supreme Court Justice Michael Buss agreed. ``The appellant only intended by the false statements to construct a foundation for seeking to have the traffic infringement notice withdrawn on discretionary grounds," Justice Buss said.
