Pritchard,^ the mandatory injunction prayed for was refused, but the jurisdiction of the court to grant the same in proper cases was asserted. It was contended in this case that a mandatory injunction should not be granted where the damage was complete before the filing of the bill ; but the court held that relief by way of injunction ought not to have been refused upon the mere ground that the damage had been completed before the bill was filed. " The authorities upon this subject," said the court, " lead, I think, to these conclusions : that every case of this nature must depend upon its own circumstances, and that this court will not interfere by way of mandatory injunction, except in cases in which extreme, or at all events very serious, damage will ensue from its interference being withheld." The matters complained of by the plaintiff were interferences with an easement of way and an easement of ancient light, but the interferences were found not to be extreme or serious, and plaintiff was permitted to sue at law for his damages.
