If they are prosecuting and you don't show up in court, you'll just have to pay the ticket then, not now. But the odds are very great that you'll never have to pay it. Although the decision does not impair the right of an individual to raise specific Charter defences to a particular ticket, it failed to find the overall scheme invalid. Interestingly, the Crown has indicated that they will not be entering Section 1 Charter evidence. Please consider attending court to show support for Stead and opposition to the unconstitutional photo radar legislation.
