Traffic Lights, Signs and Controls: Stop Sign - 22450(A)

My question involves a traffic ticket from the state of: CA

I was ticked in Jan 2019 for allegedly failing to stop at a stop sign. I mailed an informal discovery request to the CHP, who after almost two weeks have declined to reply. What are the odds that if I do a trial by written declaration and ask for dismissal based on lack of discovery that I will win...?

Thanks!
