In theory, your thinking is correct. When a client hires me to fight their NYC moving violation, my main practise, I never ha e the tickets mailed in. Although ver small, there is a percentage of times that the PO does not hand in his ticket. However, a week is WAY too early to even think that in this case. None appear on the computer before 3 weeks generally, and most take longer. The 15 days is not true. You have 35 and it must be on the system. That being said, you will need to be vigilant and keep checking or hire an attorney who does this regularly.
