Regina v Clayton [2014] EWCA Crim 1030; [2014] WLR (D) 231
‘Where there was information suggesting that an enforcement notice should not have been issued, a prosecution for breach of the notice was not open to challenge as an abuse of process because that would involve a challenge to the validity of the enforcement notice and such a challenge could be mounted only on appeal or by way of judicial review.’
