That would sound like garbage and you know it. Exhaust leaks sound nothing like atmo venting screamers. Interesting advise coming from a police officer though, as this would also be clearly illegal.
So you think that you, the police, get to play judge and jury as to what the fine should be? We have seperation of powers for this exact reason.
Interesting, so you're admitting that police officers you know have made decisions based on handing out infringements of breaking the law, not on the law that was broken, but the attitude of the person? Again, we have seperation of powers for this reason. We also have courts to overturn these fines handed out by overzealous police officers who believe they hold the power to decide what punishment is fit.
I hope you have lied about your position as a police officer. As you are clearly the problem with police today, you just have no idea. Maybe you should refresh your training, and your mates while your at it by taking a quick look at the QLD transport website. I make reference to this article. http://www.transport.qld.gov.au/resources/...ion_jan05v2.pdf there are many modifications which require NO engineers certificate as you mention. So once again, the guy who returned everything to stock was misinformed and probably misled by police such as yourself who are unaware of the law.
Dodgy road worthies have been happening for years and the fine that it carries is primarily based towards the person who is doing the road worthy. Not the motor vehicle owner. The mechanic is the certified professional. The car owner is taking their car there for certification of road safety and hence is not liable for the actions that the mechanic takes. I don't agree with dodgy road worthies but it's not the owners fault if the mechanic is dodgy.
Make of this what you will. I look forward to your response.
