Unfortunately some, if not most, of this is inaccurate.
You cannot transfer this to a local county court as they do not have jurisdiction. The Traffic Enforcement Centre in Northampton was established for the purpose of processing statutory declarations and witness statements in relation to decriminalised enforcement.
The driver of the vehicle is irrelevant as owner liability for the penalty charge applies. Photographic evidence of who this is would be of no value.
The TEC will not be interested in representations against the penalty charge, this is not their concern. Their purpose is to reset the appeal process where a step has been missed and/or where statutory procedures have not been followed. This applies to BOTH sides.
You can claim costs but £18 per day is not an established figure. Costs can be applied for, by either side, to the adjudicator at the independent tribunal (either London Tribunals or Traffic Penalty Tribunal) but these are rarely awarded.
The burden of proof does NOT rest with the authority. This is not a criminal case, it is a civil one. If it goes to appeal, the adjudicator will decide the matter based on the balance of probabilities. Their decision is binding on both sides but are not precedents.
Finally, this is not an 'offence' as that relates to criminal activity. It is an alleged contravention.
