The region of York took these cases to the C of A, so they could have a precedent set. Most JP's wouldn't consider these minor errors as "fatal flaws", but some "may". Now they no longer have that option as a precedent has been set. I see it primarily as "housekeeping" type of exercise
No doubt, but the door is now open for the crown/police to push the limits of what might be considered "minor". The old saying of "give them an inch..." applies here. True, many motorists are boneheads, but the crown/police have repeatedly demonstrated that bullying citizens when it suits their (sometimes questionable) needs is wholly acceptable.
