Thank you for that additional information, that will be helpfull in allowing me to advise you today.
From your account, it appears that you may have been summons for fly tipping.
You would need to attend court for the offence. I would advice seeking help from a criminal law solicitor. The offence should be covered by legal aid.
The solicitor would ask for copies of the recorded interview and if these cannot be produced, make seek a dismissal of the case on a technicality. Although to be summons to court there does don't need to be an interview, but they still need sufficient evidence.
The court may not be impressed that the car was so heavily loaded with wood that the exhaust was on the road. That is an offence in itself. You would need to convince a court that you were not just going to abandon the wood in the bush. The court my be sceptical to believe that you would retune to collect it from inside a bush and that it was not just going to be left there.
If the court accept your account, that case would be dismissed, if not it would be fine.
Take your receipt from the garage with you as this could be good evidence to assist your case.
