Below is the procedure that i have used in the past and found to be successful.

1. Make a copy of the ticket for my records (front and back)
2. Check the contested Box and send it in to the courthouse.
3. Request Discovery from the prosecutor ( they are located at KCDC Burien) I personally serve the request on their office, take two copies, one for them, and one for you. they will stamp it "recieved" then walk over to the clerk to file that prooving to the court that you have given your request to the prosecutors office.
4. Wait for your court date and discovery package to come in the mail.
5. 1st thing 1st, when you recieve the discovery, VERIFY THE FILING DATE, REMEMBER irlJ 2.2D GIVES THE OFFICER FIVE DAYS EXCLUDING WEEKENDS AND HOLIDAYS TO FILE THE TICKET WITH THE COURT when you get your discovery, the ticket should be stamped by the clerk with the file date, look at a calendar to verify. You can call the clerk, but note that they write in the docket everytime you call.....doesnt really matter but i dont want the judge seeing that i keep bugging the clerks etc :-)
6. review the officers affadavit closely. look for foundation to the affadavit etc, make sure it is certified pursuant to rcw 9a.72.085 etc.
7. when you recieve your discovery, post it up here on the board, word for word. I am sure there are a few of us that can give you an idea of what "we" would do if it was our case.
8. If you contest a case, and go to court, you can make preliminary motions based on the evidence being used against you. IE, the officers affadavit. Making a motion to surpress an affadavit is simple, as it is usually very easy to argue lack of foundation.
9. My understanding of it is if preliminary motions are denied, you can ask the court for the deferral as nothing has been entered into the record unless of course the judge rules in favor of your motion, therefore the hearing technically hasnt started yet. (others may think differently on this but like i said, just my thought)
10. Let us all know when you have your discovery package so we can all chime in.

Its always fun to see what others are fighting against. I personally have a case that i am getting ready to post up (speeding and cell phone use by WSP on 18 by SMD)

Good Luck!!
