May a property owner use a spring gun capable of inflicting death or serious injury to protect personal property in an unoccupied farmhouse against trespassers and thieves, without incurring liability for resulting injuries?

Bertha Briney inherited an 80-acre tract in Mahaska County, Iowa, containing the farmhouse where her parents and grandparents had lived. The house sat unoccupied from 1957 onward. Over roughly ten years, trespassers repeatedly broke into it, took household items, broke windows, and damaged the property. The Brineys boarded up doors and windows and posted "no trespass" signs, but the intrusions continued.

On June 11, 1967, Edward and Bertha Briney set a 20-gauge shotgun in a north bedroom, secured it to an iron bed, and wired the trigger to the doorknob so it would fire when the door opened. Edward Briney lowered the aim from the stomach to the legs at his wife's suggestion, admitting he acted because he was "mad and tired of being tormented." The gun was concealed, tin was nailed over the window, and no warning was posted.

On July 16, 1967, Marvin Katko and a companion entered the house through a porch window to find and steal old bottles and fruit jars. When Katko opened the bedroom door, the shotgun fired and blew away much of his right leg, including part of the tibia. He spent 40 days in the hospital, suffered permanent deformity, and incurred substantial medical expenses and lost earnings. Katko had pleaded guilty to nighttime larceny and was fined and paroled.

Katko sued the Brineys in the Iowa trial court for damages from his injuries. At the Brineys' request, the action was tried to a jury of residents of the community where the property was located. The jury returned a verdict for Katko of $20,000 in actual damages and $10,000 in punitive damages. The Brineys moved for judgment notwithstanding the verdict and for a new trial, and the trial judge overruled both motions and entered judgment on the verdict. The Brineys appealed to the Iowa Supreme Court.

(Moore, C.J.)

No. An owner may not protect an unoccupied building and its personal property against trespassers and thieves with a spring gun capable of causing death or serious injury. The judgment for Katko is affirmed.

The law places a higher value on human safety than on property rights. Absent a threat to personal safety justifying self-defense, no privilege exists to use force calculated to cause death or serious bodily injury to repel a threat to land or chattels. Prosser on Torts; Restatement of Torts § 85; Harper and James, The Law of Torts § 27.3.

An owner cannot do indirectly, through a mechanical device, what he could not do directly if present. Had the Brineys been present, they could not have shot Katko merely for breaking into an unoccupied house to steal old bottles. A spring gun is therefore not justified against a mere trespasser or petty thief, only against those upon whom the owner, if present, could lawfully inflict the same injury.

Iowa precedent is consistent. Hooker v. Miller, 37 Iowa 613, held a vineyard owner liable for a spring gun injury to a grape thief, stating that trespassers "are not to be visited by barbarous punishments or prevented by inhuman inflictions of bodily injuries." Out-of-state authority is in accord, including Allison v. Fiscus, Starkey v. Dameron, and Wilder v. Gardner. Many jurisdictions also impose criminal liability for injuries or deaths caused by spring guns.

The jury instructions correctly stated the law, and there was substantial evidence supporting the jury's findings of malice and wanton and reckless disregard. The Brineys never challenged the availability of punitive damages in the trial court, so that question was not preserved and the court expressly declined to decide whether punitive damages are proper in this type of case.

Dissent (Larson, J.) The majority wrongly assumes the Brineys intended to shoot an intruder, when intent was a disputed fact question. Both defendants testified the gun was set to scare or frighten intruders, not to seriously injure them. Absent a statute barring spring guns, liability should turn on whether the owner intended to kill or seriously injure the intruder and used unreasonable force, and the owner should be liable only for negligence otherwise. The trial court's Instructions 2, 5, and 6 were confusing because they blurred whether mere installation created absolute liability or whether intent to harm was required, and the jury was never clearly asked to decide intent. The case should be reversed and remanded for a new trial.

Larson also would hold that punitive damages should never have been submitted to the jury. Allowing a person engaged in a serious crime such as breaking and entering to recover a windfall of punitive damages shocks the conscience and lets a criminal profit from his own crime. The criminal law, not tort law, is the proper vehicle for punishing wrongdoers, and compensatory damages are a sufficient deterrent. He would hold the $10,000 punitive award void and criticizes the majority for upholding it on a mere technical rule of civil procedure. The majority answered that it is a court of review, that the defendants' attorneys had a duty to raise the issue in the trial court, and that it will not consider a contention raised for the first time on appeal.
