Unfortunately, the appellant in that case didn't provide the assessors name or the POPLA reference number. It can be referenced but without those two details, it will hold little weight for the assessor of this appeal.
I think that there should be enough in this appeal to persuade the POPLA assessor but, as always with POPLA, you don't know who is doing the assessment and they have some truly moronic assessors on staff at the moment, who have shown incredible lack of understanding of the law and the PPSCoP.
Anyway, if POPLA don't accept the appeal, it would be very easily defended in court if MET are going to play silly buggers and try and escalate it that far.
