“This contention is in my judgment untenable. Harper v Hayden was not a decision which, despite what was said in it about the decision in Lingke’s case, decides anything more than that where an owner of premises adjoining a highway is conducting building works and, for the protection of the public, erects a hoarding which obstructs the highway for no longer than reasonably necessary, he commits no wrong. This is in accord with both Herrins and Lingke. To extend this to obstructions by local and other authorities in the exercise of statutory powers would be to deprive section 278 of all content. It would enable a Water Authority to close completely a street of shops for a year or more if it was reasonably necessary thus depriving shopkeepers of their livelihood for a year, and yet say that there was no right to compensation. A construction on the section leading to such a result would be to attribute to Parliament an intention which amounts almost to confiscation without compensation. I can attribute no such intention. Moreover, such a construction would be against the ordinary meaning of the words ‘common sense’ and ‘authority’. ”
“(4) In the event of the landlord failing to do the requisite repairs within a reasonable time after notice, the tenant is entitled to sue him in damages without first incurring expense by doing the repairs himself (Hewitt v. Rowlands (1924) 131 L.T. 757). (5) The covenant is clearly not specifically enforceable, but I apprehend that, in the event of the landlord failing to do the repairs in a reasonable time, the tenant can, at his option, do the requisite repairs himself and claim the proper cost of so doing as damages flowing from the breach. ”
“It shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees”
“1450. Law should serve the public interest . It is the basic principle of legal policy that law should serve the public interest ... Where a literal construction would seriously damage the public interest, and no deserving person would be prejudiced by a strained construction to avoid this, the court will apply such a construction. In pursuance of the principle that law should serve the public interest, the courts have evolved the important technique known as construction in bonam partem (in good faith). If a statutory benefit is given only if a specified condition is satisfied, it is presumed that Parliament intended the benefit to operate only where the required act is performed in a lawful manner. ” “1453. Illegality ... Unless the contrary intention appears, an enactment by implication ... imports the principle of legal policy embodied in the maxim nullus commodum capere potest de injuria sua propria (no one should be allowed to profit from his own wrong). The most obvious application of this principle against wrongful self-benefit relates to murder and other unlawful homicide.” 46. Bennion on Statutory Interpretation, 5th ed (2008), section 264, also discusses the principle that law should serve the public interest. It comments that “all enactments are presumed to be for the public benefit” and that “[t]his means that the court must always assume that it is in the public interest to give effect to the intention of the legislator, once this is ascertained"; and, later, that “Construction in bonam partem is related to three specific legal principles. The first is that a person should not benefit from his own wrong”
“53. Since the ultimate question is whether it can have been the intention of the legislator that a person conducting himself like Mr Beesley can invoke the benefits of sections 17IB and 191(1), I do not consider that there can be any absolute principle that public policy can only bear on the legislator's intention in a context where there has been the commission of a crime. The principle described in the passages cited from Halsbury and Bennion is one of public policy. The principle is capable of extending more widely, subject to the caution that is always necessary in dealing with public policy. Some confirmation that the need for an actual crime is not absolute can also be found in another case, R v Registrar General Ex v Smith[1991] 2 QB 393 , where the Court of Appeal held it sufficient to disentitle a prisoner from exercising his on its face absolute right to inspect his birth certificate that there was a current and justified apprehension of a significant risk that he might in the future use the information thereby obtained to commit a serious crime. ”
“In my opinion what we have to consider is whether the obstruction in the present case was caused and was continued by the act or default of the defendants, and not whether it was caused and continued through their act, default, or sufferance. I cannot construe the word "default" here in the way in which we have been asked to construe it by the rural district council. I do not think that in this case "default" could mean merely doing nothing, unless an obligation to do something were imposed by the Act. There was no act of the defendants which caused the obstruction either to arise or to continue. I can well understand that there might be a case where it might be said that a person who failed to do something which he ought to have done, such for instance, as failing to prevent obstructive matter from going into a river from his own premises, had caused an obstruction by his default. In the present case, on the facts found by the justices, there is nothing to show that the defendants did anything which caused this obstruction to arise or to continue; nor do I think that there is anything which can properly be called a default on their part, although there might have been facts which amounted to a sufferance; but that word, I repeat, does not occur in the particular proviso with which we are concerned. ”
