"The fact that we have found that the appellant was out of the country does not make the proceedings oppressive. In my judgment when a person is aware - as the appellant was - of enforcement proceedings, and could reasonably anticipate re-service of them, having once complained that he had not received them, when such a person could reasonably be expected to make arrangements to be informed about such re-service, either by having someone collect and open his post, which would be - was - as is agreed, clearly marked relating to his property, he could have notified the authority in advance of his extended absence from the country, or he could have made arrangements through other means, potentially through his landlord, or otherwise, to be notified where he was to be in Germany, either by telephone or otherwise."
"Where (a) a person charged with an offence under the section has not been served with a copy of enforcement notice; and (b) a notice is not contained in the appropriate register kept under Section 188 It shall be an offence for him to show that he was not aware of the existence of the notice."
