Electricity company caused structural damage to a house and nuisance to its occupier. The trial judge awarded damages but refused an injunction. The CA reversed this allowing an injunction.
Many judges have stated, and I emphatically agree with them, that a person by committing a wrongful act (whether it be a public company for public purposes or a private individual) is not thereby entitled to ask the Court to sanction his doing so by purchasing his neighbour's rights, by assessing damages in that behalf, leaving his neighbour with the nuisance, or his lights dimmed, as the case may be. In such cases the well-known rule is not to accede to the application, but to grant the injunction sought, for the plaintiff's legal right has been invaded, and he is prima facie entitled to an injunction.
There are, however, cases in which this rule may be relaxed, and in which damages may be awarded in substitution for an injunction as authorized by this section. In any instance in which a case for an injunction has been made out, if the plaintiff by his acts or laches has disentitled himself to an injunction the Court may award damages in its place. So again, whether the case be for a mandatory injunction or to restrain a continuing nuisance, the appropriate remedy may be damages in lieu of an injunction, assuming a case for an injunction to be made out.
In my opinion, it may be stated as a good working rule that --
(1) If the injury to the plaintiff's legal rights is small,
(2) And is one which is capable of being estimated in money,
(3) And is one which can be adequately compensated by a small money payment,
(4) And the case is one in which it would be oppressive to the defendant to grant an injunction: --
then damages in substitution for an injunction may be given.
There may also be cases in which, though the four above-mentioned requirements exist, the defendant by his conduct, as, for instance, hurrying up his buildings so as if possible to avoid an injunction, or otherwise acting with a reckless disregard to the plaintiff's rights, has disentitled himself from asking that damages may be assessed in substitution for an injunction.
