Just to confirm, are you the registered keeper of the vehicle?
So from what you have posted it seems like the following is a rough summary of what has happened so far:
- Euro Car Parks issued a charge
- You appealed as the registered keeper, on the basis that you were not driving
- Euro Car Parks rejected this appeal, claiming they have complied with Schedule 4 of the Protection of Freedoms Act (PoFA), and are therefore able to recover the charge from you as the keeper
- You chose not to appeal to POPLA (is this correct?)
- Instead you engaged in further correspondence with Euro Car Parks, reiterating your initial position
As I stated in my previous reply, the fact that you were not driving is only a defence if Euro Car Parks have not complied with PoFA. They claim that they have - we cannot ascertain whether or not they have without a copy of the initial notice, which you do not seem to have. It might be wise to submit a Subject Access Request to the Data Protection Officer at Euro Car Parks, to get a copy of this.
Another option is to provide the name and address of whoever was driving, if you know who it was, and Euro Car Parks should then pursue them instead.
