Somewhat true, but the poilce take everything to court, regardless of cost. A few hundred dollars is nothing! In this case the officers superiors would probably have said "bad luck, be a bit more careful next time and give him undue noise" and left it at that, i've had many dealings with police and police prosecutors including a family member who was an inspector. The police rarely get in trouble for incorrectly handing out traffic fines. It takes something much worse for an officer to be diciplined. Anyone can take their fine to court and get off, but thinking you're having an effect on the police is diluted, it takes serious misconduct to have an officer diciplined. At the end of the day they don't like losing cases, but it just teaches them to be more careful and tactful in handing out fines. Things such as the anti-hoon legislation keep coming in to aid the police in this war against "hoons", you can get off your fine but you can't stop their cause, it's backed by consensus public policy and that's all that matters.
