It is the latter, private company National Parking Enforcement LTD. It was an 'independent' appeals adjudicator from IAS. This is what I received;
"It is important that the Appellant understands that the adjudicator is not in a position to give his legal advice. The adjudicator's role is to look at whether the parking charge has a basis in law and was properly issued in the circumstances of each particular case. The adjudicator's decision is not legally binding on the Appellant (it is intended to be a guide) and they are free to obtain independent legal advice if they so wish. However, the adjudicator is legally qualified (a barrister or solicitor) and decides the appeal according to their understanding of the law and legal principles.
The terms of this appeal are that I am only allowed to consider the charge being appealed and not the circumstances of other drivers or other parking events. The guidance to this appeal also makes it clear that I am bound by the law of contract and can only consider legal challenges not mistakes or extenuating circumstances. The Operator’s signage, which was on display throughout the site, makes it clear that the terms and conditions of parking are in force at all times and that a PCN will be issued to drivers who fail to comply with the terms and conditions of parking, regardless of a driver’s reasons for being on site or any mitigating factors. It is the driver’s (rather than a third party’s) responsibility to ensure that the terms and conditions of parking are properly complied with. While noting the Appellant's comments, it is clear from the evidence provided to this appeal that the Appellant did indeed park otherwise than in accordance with the displayed terms.
I am satisfied that the Operator has proven their prima facie case. Whilst having some sympathy with the Appellant’s circumstances, once liability has been established, only the Operator has the discretion to vary or cancel the parking charge based on mitigating circumstances. Accordingly this appeal is dismissed.
Thank you very much for your time
