Prosecution notice period

[Howcoulditbe]

I just got stopped for no seatbelt and when they did a person check it churned out that I had a 'pending' from 2004. When I asked the PC further, they advised me i had a case pending for driving with no insurance since 2004. Today (Dec 07) is the first im hearing about it, I've never had any communication or ever been stopped for no insurance!

How could i have this case against me? i know its a serious offence so surely they would have prosecuted me by now if they were going to? Don't they have set periods in which they need ot inform you of intended prosecution by?

Any advice would be much welcomed until I can get a copy of my file from the police under the DPA rules (as advised by the pc who stopped me) and consult my lawyer!
