Facts

Plaintiffs were farmers whose alfalfa crops, vegetation, flowers, screens, and use of their property were affected by sulphur-dioxide fumes emitted from defendant's Alma plant over several years. Plaintiffs tried the case on a nuisance theory, asserting that the fact of the emissions and resulting property damage mattered, not whether the emissions could be controlled through due care. The jury found a continuing nuisance and awarded crop damages for 1965 and 1966, and found a $500 diminution in market value for only one farm. The trial court changed the jury's answer on whether the nuisance caused substantial damage from no to yes, and had excluded defendant's evidence that it used due care and that the plant's social and economic utility outweighed the harm.

Issue

Whether, in a nuisance action for damages based on air pollution, the defendant may defeat liability by showing due care or by showing that the utility of its enterprise outweighs the plaintiffs' harm. The court also considered whether the injuries here were substantial as a matter of law and whether the continuing nuisance required recovery for permanent diminution in market value.

Rule

A cause of action depends on operative facts, not labels such as negligence or nuisance. In Wisconsin, for a private nuisance damages action, freedom from negligence and conformity with industry standards do not defeat liability when the conduct creates a nuisance causing substantial injury; nor may the defendant avoid damages by showing that the social or economic utility of its enterprise outweighs the harm. Physical damage to tangible property constitutes substantial injury, and when a continuing nuisance causes permanent injury to land, future recovery is measured by diminution in market value rather than repeated annual itemized damages.

In Madison, Wisconsin, Elena Ruiz sued North Bluff Aggregates after dust from its stone-crushing operation repeatedly settled on her greenhouse roof and damaged seedlings. Her complaint alleged the dust emissions, the resulting property damage, and that the company continued operating after complaints, but it did not force an election between negligence and nuisance theories.

If North Bluff Aggregates moves to dismiss on the ground that Elena failed to choose a single theory of recovery, how should the court rule under the majority opinion's approach?

Explanation. The majority held that a cause of action depends on operative facts, not the label attached to them. If the pleaded facts show an invasion of a protected right and could support recovery under any legal theory, the pleading is sufficient, even if the facts might fit both negligence and nuisance. The plaintiff need not make a fatal early election merely because both theories are conceivable. (Derived from Jost v. Dairyland Cooperative (1969).)
