There is a battle going on in the courts here in the UK between a trucking business and the speed camera operatoring company. Seems they have been done a number of times by the same camera. They are arguing that they know where the fixed camera is and are not stupid enough to keep speeding through it. Are attempting to use tachograph records to show were not speeding. Their argument is that the tachograph is certified accurate by the government and it shows they are not over the speed limit. The government can and has used tachograph records in prosecutions on a regular basis. One or the other has to be wrong.

Was it not the Victorian state government which attempted to prove in court that an old Datsun 120y was doing over 100 miles an hour which was faster than the manufacturer said it could do when new.

Or the Queensland government which when losing speeding cases due the mobile radar not be calebrated just chanaged and back dated the law to make the inaccurate reading legal so as the fines would stick.a
