Submit reps on the basis that the PCN is unlawful because it is demanding payment of the toll fee as well as the penalty charge. Regulation 7 of the Road User Charging Schemes (Penalty Charges, Adjudication and Enforcement) Regulations 2013 regulations does not give powers to demand the toll fee in the penalty charge notice. This is confirmed by a adjudication case in 2018 at the Traffic Penalty Tribunal. Birmingham City Council, no doubt with better lawyers who have actually read the regulations, do not request payment of their CAZ toll in their PCNs.
Quote the TPT case, and the name of the adjudicator.
