Whether a court may deny an injunction against a substantial private nuisance merely because the economic cost of abating the nuisance would greatly exceed the plaintiffs’ damages.
Holding
No. Under established New York nuisance law, a plaintiff who proves substantial damage from a continuing nuisance is ordinarily entitled to an injunction despite a disparity between the plaintiff’s loss and the defendant’s cost of compliance.
Reasoning
The lower courts’ balancing approach conflicted with settled New York precedent. In Whalen v. Union Bag & Paper Co., the Court had held that a nuisance causing more than unsubstantial harm must be enjoined even when the defendant’s expense of abatement far exceeds the plaintiff’s injury. Earlier cases followed the same rule.
The exceptions to that rule did not apply. Cases denying injunctions involved either no actual injury or no meaningful benefit to the plaintiff from an injunction. Here, the trial court found concrete and substantial property damage and awarded damages to the individual plaintiffs. Therefore, an outright denial of injunctive relief could not stand.
