When I was younger I was fighting a speeding ticket. Followed a lot of the stuff mentioned in this thread. (people have been doing this disclosure/11b "trick" forever)
So I request disclosure. I received the officers notes, but they are incomplete. I re-requested disclosure, I got it and it's still incomplete. Doesn't mention anything about my traffic stop or testing the gun before or after even though I specifically requested those things.
Spoke with a friend who is a court appointed attorney. They gave me some pointers about what to say in court and how to point out what's missing in my disclosure and how I have a right to full disclosure before trial and blah blah blah.
My friend even tried to speak with the Crown before hand about my lack of proper disclosure. He told her he has a "button" under his desk and he just "presses" this button and gets convictions all day long.
So I do the trial thing and the I bring up that my disclosure is lacking all the things the crown is using against me. The officer looks at my disclosure and admits it is missing a lot. Crown says it doesn't matter what the officers notes say. JP scorns me saying "You thought you could win because of this?" So needless to say I don't "win".
I go through the appeal process (which is a joke in itself and takes up a lot of your time and money) after almost 2 years I cancel the appeal. I got a civilian job with the Police and didn't want the trouble. Also, because it was gonna take longer than it was gonna be on my record.
Now that the appeal process is cancelled, the ticket/fine (which I haven't paid for all this time because I filed a motion to hold payment due to the appeal and was granted) immediately goes into default and I receive a notice in the mail saying my license is going to be suspended for lack of payment. I had to visit city hall and deal with that BS to get it all settled and ironed out.
Moral of the story: Sometimes no matter how hard you try and how closely you play the game, we really have no power at all. A lot of the time JP's/Crowns don't take civilians playing lawyer very seriously.
Fight the ticket or not, the outcome is in their hands.
Your mileage may vary.
