"Where at any time after the end of the period for compliance with an enforcement notice, any step required by the notice to be taken has not been taken or any activity required by the notice to be ceased is being carried on, the person who is then the owner of the land is in breach of the notice."
"Where the owner of the land is in breach of an enforcement notice he shall be guilty of an offence."
"in proceedings against any person for an offence under sub-section (2) it shall be a defence for him to show that he did everything he could be expected to do to secure compliance with the notice."
"The meaning of section 179 is clear and unambiguous. Where it is within the power of the owner of the land to comply with the notice without the assistance of others no question of a defence under sub-section (3) arises. Before a defence can arise under that sub-section the owner must show that compliance with the notice is not within his own unaided powers otherwise no question of his having to secure compliance with the notice can arise. Thus, if there are other persons in occupation of the land, it is enough if he has done everything he could reasonably be expected to do to secure that they comply with the notice. If compliance would require, for example, some engineering work and the owner is not himself able to do that work and does not have the resources to employ another to do it, he will have a defence if he can show that he did everything he could reasonably be expected to do to secure compliance with the notice. These examples suffice to illustrate the application of sub-section (3). We accept as does counsel for the prosecution that the phrase 'everything he could be expected to do' must implicitly be read as 'reasonably expected'. It applies an objective criterion of reasonableness having regard to all the relevant circumstances, in particular any disability to which the owner of the land is subject."
"In the course of argument Mr Crean accepted a proposition which I put to him, namely that his submission would mean that sub-section (3) is available in circumstances where the defendant, though perfectly able physically and financially and legally, to comply with the enforcement notice did not do so because for good reason he did not wish to comply with it. In my judgment that exposes the flaw in Mr Crean's argument. Sub-section (3) is not concerned with a balance of social factors. It is not concerned with such policy issues as arise in relation to the circumstances in which gypsies live. It does not enjoin a court to accept a defence on the footing only that it concludes that it would be a good thing if the defendant were not required to comply. Indeed it is not at all concerned with the defendant's wishes; only with his capacity. It is there to protect an individual who shows that in reality and common-sense he is unable to comply with the obligations imposed on him by an enforcement notice as owner."
"It seems to me that the plain meaning of those words does indeed permit the personal circumstances of a defendant to be taken into account. I bear in mind in reaching that conclusion that this section creates a criminal offence. To hold someone guilty of a criminal offence for not doing something which they are genuinely incapable of doing, would be quite contrary to any tenets of criminal law known to me at least."
