I've been trying to find the case law which outlines the elements of the offence for speeding. Not much luck yet.

The complete offence is speeding. No different than the charge of Disobey Sign. It doesn't outline the complete offence either. They way it was explained to me is that the JP has to find the offender guilty or not guilty of speeding first. The offence is complete even at 1 km/h over. The prosecutor then has to quantify the speed as part of the officers testimony by using some type of speed measuring device. (Lidar, Radar, Pacing etc.)Writing the amount of speed in excess simply speaks to attached penalty. This would be part of the officers disclosure, either from notes written in the notebook, or on back of the ticket.
Worse case is that the JP does not find a fatal flaw and you file to have the ticket re-opened.
