The councils will say that they don't refund paid
PCN's since you have accepted the charge is correct by paying it. However they obviously must make payouts at times-when a Court for instance, or PATAS, has ruled that the
PCN is invalid, for whatever reason and someone then reclaims their money as a result.
In such circumstances, [A Court or Patas ruling] on say the wording of a
PCN for example, which should therefore apply to all similarly worded PCN's, does
that make it encumbent on the Council to repay the ticket or do they dig in and hope to fob you off?
