My line of thinking is that the OPP simply do their re qualifications more often than the Province requires. Under Provincial guidelines they are not required to do so. Even if they don't re qualify within the 2 year period I believe they are still qualified to operate speed measuring devices in Ontario.
You could try discussing this with the prosecutor prior to the trial and see what they say. They may not even be aware in the discrepancy between the standard and OPP policy.
The OPP Police Orders are more stringent, and state that if the officer has not maintained their training they should not be operating a speed measuring device
. The Orders also state that when in conflict with the Provincial 'guidelines' and are more stringent - then the Orders will take precedent.
Else, what is the point of having specific OPP police Orders, York Regional Policy, Brantford, etc... ? The Provincial Standards are guidelines - the individual agencies (i.e. OPP) write their own internal policies to meet the standards. They should be measured and held accountable to their own internal policy.
