Morgan v. High Penn Oil Co.
Citation and Court
Morgan v. High Penn Oil Co., 77 S.E.2d 682 (N.C. 1953)
Facts
High Penn Oil Company operated an oil refinery near the Morgan family’s home and restaurant. Approximately four times per week, the refinery emitted noxious gases and odors that made the Morgans and their guests ill and prevented them from using and enjoying their property. The refinery operated without negligence — it was using reasonable care — but the emissions continued to interfere substantially with the Morgans’ use of their land.
Issue
Is an oil refinery liable for private nuisance when its emissions substantially interfere with neighboring landowners’ use and enjoyment of their property, even if the refinery operates without negligence?
Holding
Yes. The North Carolina Supreme Court held that the refinery’s emissions constituted an intentional, unreasonable private nuisance, and affirmed the injunction and award of damages.
Rule / Doctrine
Private nuisance liability does not require negligence. An intentional nuisance occurs when the defendant knows or should know that its activities are substantially interfering with another’s use and enjoyment of land and continues regardless. Once the interference is shown to be intentional (in the sense that the defendant knows it is occurring), the question is whether it is unreasonable — typically assessed by balancing the gravity of the harm against the utility of the defendant’s conduct. Lack of negligence is not a defense.
Significance
Morgan v. High Penn Oil Co. is a leading case for the principle that nuisance is a separate tort from negligence and that reasonableness of conduct does not insulate a defendant from nuisance liability. The case is important for clarifying the “intentional” element in nuisance — it does not mean the defendant intended the harm, only that the defendant continued knowing the interference was occurring. The case is frequently taught alongside the Restatement (Second) of Torts §§ 822–826 balancing framework.
