I represented myself once in a traffic offence case. I proved in court that I would have to have been doing 100mph to have done what I had been accused of. This was odd because the policeman in the witness box had just agreed that I had been driving at 50mph. I got banned from driving and 5 points on my licence. By happenchance I had learned that the policeman was emigrating at the end of the month so while I was still in the court I asked for an appeal. The police prosecutor had a whisper with the magistrate who then informed me that I had to fill out the papers and hand them in before I left the courthouse.
No! No! No!
The papers stated that they had to be submitted within 21 days.
I waited 18 days and sent them in. I had to go to the Crown court to be told that there now was no evidence so my ban was negated. I asked for costs and was told to fuck off!
