I was given a ticket (code 22350) for going 61 in a 50. I contested the ticket and sent an Informal Discovery Request to the city and county DA as well as the CHP office that gave me the ticket. I received the information on the back of the ticket from the police station but no speed survey (which I have in my possession anyway thanks to the law library). As for the County DA I recieved a letter stating,
"the court is not a party to the action you reference. We do not accept any sort of documentation relating to Discovery. When you determine the appropriate parties to serve with this request you may bring a Motion before the court relating to the Non-compliance of requests for Discovery if you need to do so to compel the documentation you seek."
After reading some threads here it seems that they in fact are responsible for answering to my request--is that true? If not what is my next step and is this a cause for dismissal yet?
Secondly I have the speed survey and the critical speed at the place I was clocked is 57, that seems to justify a speed trap since the speed limit is 50.
The only fishy thing is that the front of the ticket says he used radar but his notes on the back read, " V.65 R.65 Car in Front 61 Overtake by ______" i can't make out the last word it looks like laurel but I really cant tell--does this mean he did or didn't use a radar and does that even matter in my defense?
Any and all advice is appreciated--Thanks.
