Think about this next time you go to court to fight a traffic ticket.
Pay particular attention to the last paragraph...
*...A justice of the peace is a judicial officer who performs such duties as issuing search warrants, deciding who is freed on bail, and presiding over offences under the Highway Traffic Act, such as speeding. They do not have to be lawyers. They are appointed to the position by the attorney-general, acting on the recommendation of committees made up of a senior judge, lawyers and representatives of the community...*
The guys YOU face in traffic court are not judges; they are appointed political hacks.
Tells you a lot about our Justice system, and the fairness of the JP's...they are NOT experts in anything, particularly traffic laws.
