“What, then, are the principles which a court should apply in a case of this type? It seems to me that, first, prima facie a landowner, whose title is not in issue, is entitled to an injunction to restrain trespass on his land whether or not the trespass harms him. In support of that proposition there are two comparatively recent cases at first instance. The first is Woollerton and Wilson Ltd. v. Richard Costain Ltd. [1970] 1 W.L.R. 411, which was a reserved judgment of Stamp J., and from the report I note that Behrens v. Richards[1905] 2 Ch. 614 was cited in argument, though the judge does not refer to it in his judgment. Stamp J. said, at p. 413: “It is in my judgment well established that it is no answer to a claim for an injunction to restrain a trespass that the trespass does no harm to the plaintiff. Indeed, the very fact that no harm is done is a reason for rather than against the granting of an injunction: for if there is no damage done the damage recovered in the action will be nominal and if the injunction is refused the result will be no more nor less than a licence to continue the tort of trespass in return for a nominal payment.” “It is in my judgment well established that it is no answer to a claim for an injunction to restrain a trespass that the trespass does no harm to the plaintiff.
