No. It's now too late to dispute. A charge certificate is only issued when you can no longer appeal the charge.
You will have already been issued a notice to owner, which is a document that will be sent to you after 28 days. It will tell you that you have a further 28 days to pay the full fine. It will have gone to the same address as your charge certificate.
We will register the debt at the Traffic Enforcement Centre (TEC) and send you the court order. You can then make a Witness Statement if you didn't receive the notice to owner document.
