On an appeal to an adjudicator regarding failure to pay the congestion charge under the Road User Charging (Enforcement and Adjudication) (London) Regulations 2001 reg.16(2), the adjudicator could only consider grounds under reg.13(3). He had no general power to give directions he thought appropriate where no reg.13(3) ground was established.
