Facts
- James and Joan Pestey owned and lived on residential property in North Franklin, Connecticut, about one-third of a mile from the defendants’ dairy farm.
- The defendants operated a large dairy farm and in 1990 built a free-stall barn and milking parlor with a manure storage pit.
- After the 1990 construction, the plaintiffs began experiencing odors from the farm that later grew more pungent and developed a sharp, burnt character.
- In 1997, the defendants installed an anaerobic digester intended to process manure and produce gas for energy.
- After the digester’s installation, the plaintiffs experienced stronger, persistent odors described as sulfur and sewage, interfering with sleep and prompting them to close windows.
- The plaintiffs claimed the digester was improperly operated, including venting gases to the air instead of capturing and using them, contributing to the odors.
- The plaintiffs brought a common-law private nuisance action seeking damages and equitable relief; a jury awarded $100,000 in damages.
- The trial court denied post-trial motions and entered judgment; the defendants appealed to the Connecticut Supreme Court.
Issues
- Whether the jury was properly instructed on the “unreasonableness” element of common-law private nuisance.
- Whether a property owner may testify that odors caused a diminution in the value of the owner’s property.
- Whether excerpts from a livestock waste management handbook were properly admitted under the learned-treatise exception to the hearsay rule.
- Whether the evidence was sufficient to support the jury’s finding that the defendants’ farm operations were the proximate cause of the offensive odors.
- Whether claims concerning the right-to-farm statute and exclusion of certain expert testimony were reviewable on appeal.
Decision
- The Connecticut Supreme Court affirmed the judgment for the plaintiffs.
- The Court held the private nuisance instruction properly directed the jury to assess the unreasonableness of the interference with the plaintiffs’ use and enjoyment of land, considering all circumstances.
- The Court held the trial court acted within its discretion in allowing the homeowner to testify about property value, diminution in value, and attribution of that diminution to the odors.
- The Court held the handbook excerpt was admissible as a learned treatise; the foundational testimony was sufficient to establish the handbook as a reliable authority.
- The Court held the evidence supported the jury’s findings on source and proximate cause despite competing explanations.
- The Court declined to reach certain right-to-farm and evidentiary claims because they were not properly preserved.
Legal Principles
- A common-law private nuisance claim centers on whether the defendant’s conduct causes an unreasonable interference with the plaintiff’s use and enjoyment of land; the interference may be unreasonable even if the defendant’s underlying conduct is reasonable.
- Determining “unreasonableness” in private nuisance requires a fact-specific evaluation of multiple circumstances, including the character, duration, and severity of the interference.
- A property owner is generally competent to offer opinion testimony on the value of the owner’s property and its diminution in value, and a trial court may allow the owner to attribute the diminution to an asserted cause.
- Materials may be admitted under the learned-treatise hearsay exception when a sufficient foundation establishes the work as a reliable authority; the foundation need not be an unequivocal endorsement.
- Causation in nuisance is ordinarily for the factfinder; an appellate court will not disturb a verdict where the record contains evidence from which the jury could reasonably find source and proximate cause.
- Appellate review may be denied for claims not preserved in the trial court.
Conclusion
The court affirmed a nuisance verdict against dairy farm operators, clarifying that Connecticut private nuisance law focuses on the unreasonableness of the interference with a neighbor’s use and enjoyment of property, while also approving homeowner valuation/causation testimony and the admission of technical guidance materials as a learned treatise when adequately founded.
