Dudley v API Industries, Inc.
Attorneys and Parties
Brief Summary
Residents alleged that noxious odors from a plastic manufacturing extrusion facility interfered with use and enjoyment of nearby homes, seeking class-wide relief for private nuisance and negligence.
The Supreme Court dismissed public nuisance, but denied summary judgment on private nuisance and negligence, granted class certification under New York Civil Practice Law and Rules (CPLR) 901 and 902 [class action prerequisites and additional factors], declined to strike most plaintiffs’ evidence, and struck defendant’s Exhibit R.
The Appellate Division modified by dismissing the negligence claim; it otherwise affirmed, including allowing the private nuisance claim and class certification to proceed and upholding the evidentiary rulings.
Negligence requires physical injury or tangible property damage; allegations of odors and diminished property value (including stigma damages) are insufficient. Private nuisance focuses on interference with private property rights, not the number of affected persons; the phrase “one person or a relatively few” in Copart is descriptive, not a numeric limit. Common issues predominate for class certification at this stage.
Background
API Industries operates a plastic products facility in Orangeburg. Plaintiffs living within approximately a 1.5-mile radius alleged that the extrusion process emitted noxious odors that invaded their homes, interfering with use and enjoyment and reducing property values. In 2018 they filed a putative class action for public nuisance, private nuisance, and negligence, seeking to represent residents to the north, northwest, west, southwest, and south of the facility dating back to 2015. Plaintiffs moved for class certification under CPLR 901 and 902 [class action prerequisites and additional factors]. Defendant opposed, sought to strike plaintiffs’ exhibits, and cross-moved for summary judgment. After supplemental discovery and briefing, additional motions to strike were filed by both sides.
Lower Court Decision
By order dated January 3, 2022, the Supreme Court (Rockland County) dismissed the public nuisance claim, denied summary judgment on private nuisance and negligence, granted class certification, denied in part and granted in part defendant’s motions to strike plaintiffs’ evidence, and granted plaintiffs’ motion to strike defendant’s Exhibit R.
Appellate Division Reversal
The Appellate Division modified: it granted summary judgment dismissing the negligence cause of action because plaintiffs alleged no physical injury or tangible property damage and stigma/diminution-in-value alone cannot sustain negligence. It affirmed denial of summary judgment on private nuisance, holding that numerous homeowners may collectively assert private nuisance because the claim protects private property-use rights regardless of how many are affected. It affirmed class certification, finding common questions predominate at this stage and that plaintiffs’ evidentiary submissions were properly considered, and it affirmed striking Exhibit R as irrelevant.
Legal Significance
This decision clarifies in the Second Department that private nuisance is defined by the nature of the right invaded—private use and enjoyment of land—not by a numerical limit on affected persons; large groups or classes of homeowners can assert private nuisance without converting it into a public nuisance. It also reaffirms that New York negligence claims require physical injury or tangible property damage and that stigma or property-value diminution alone is insufficient. The ruling supports class certification in environmental-odor cases where common liability questions predominate.
In New York’s Second Department, a private nuisance claim may proceed on a class-wide basis even when many residences are affected, while negligence claims based solely on odors and diminished property values fail absent physical injury or tangible property damage.
