Nice theory. Not true.Therefore if I get pulled over again I should be able to show them that I have allready been fined for this and they then cant do me for it again.
Until the tints are removed you continue to commit the offence and can be stopped again. And again. If you were to show them that you have already been fined for the tints I would expect you to be reported for prosecution. The court would increase the penalty considerably. The phrase we use is that you have failed to respond to a previous sentence so an increase is necessary.
