What are the facts?
Herrin owned and was in possession of private land used in part for hunting. While positioned off Herrin's land, Sutherland intentionally discharged a shotgun at game birds flying over Herrin's property such that the muzzle blast and pellets traveled through the column of air directly above Herrin's land. No person physically set foot on Herrin's soil, and there was no allegation of substantial physical damage to the land itself. Herrin sued in trespass, alleging that Sutherland's firing over the property was an unauthorized physical invasion of the airspace that interfered with Herrin's exclusive possessory rights. The trial court found for Herrin, and Sutherland appealed, arguing that, absent an entry onto the surface, his conduct could not constitute trespass.
What is the legal issue?
Does intentionally firing a gun so that shot and discharge pass through the airspace immediately above another's land constitute trespass even if the defendant never sets foot on the land and causes no physical harm to the surface?
What rule applies?
A landowner's possessory rights extend to the immediate reaches of the airspace above the land to the extent necessary for the use and enjoyment of the property. An intentional, unauthorized physical invasion of that protected airspace constitutes trespass, even in the absence of direct contact with the soil or proof of actual damages.
What did the court hold?
Yes. Discharging a shotgun so that its projectiles and blast pass through the immediate airspace above another's land is a trespass because it is a direct, tangible invasion of the landowner's protected possessory interest in the superadjacent air.
What is the reasoning?
The court began with the common-law maxim that ownership of land includes the space above and below it. Recognizing the impracticality of absolute, infinite airspace ownership in the modern era, the court adopted a tempered approach: a landowner owns so much of the airspace as he can occupy or use in connection with the land. Within that protected stratum—the immediate reaches necessary for ordinary use and enjoyment—unauthorized physical intrusions are trespasses. Applying that principle, the court found that Sutherland's gunfire created a physical, not merely intangible, invasion. Unlike odors, sound, or light—which typically sound in nuisance—pellets and the discharge itself are tangible objects traversing the landowner's airspace. Because the essence of trespass is the violation of the right to exclusive possession, it is enough that the defendant intentionally caused a physical thing to enter the protected space. It was immaterial that Sutherland's feet never touched the soil or that no lasting damage was shown; trespass protects possessory integrity, for which nominal damages may be awarded even absent actual loss. The court thus affirmed liability for trespass to land based on the invasion of the superadjacent airspace.
Why is this case significant?
Herrin v. Sutherland is a cornerstone in clarifying that trespass extends above the ground into the immediate reaches of airspace. It operationalizes the ad coelum maxim by limiting it to the air a landowner can reasonably use, thereby supporting modern realities (like aviation) while safeguarding core possessory rights. The case is frequently paired with United States v. Causby, which constitutionalized similar concepts in the takings context, and it provides a ready-made analytical framework for contemporary disputes involving low-altitude aircraft and drones. For students, Herrin reinforces that trespass requires a physical invasion but not necessarily contact with the surface, and it illustrates the boundary between trespass (tangible invasions) and nuisance (intangible interferences).
Does Herrin mean a landowner owns all the airspace above the land up to the heavens?
No. Herrin rejects absolute, unlimited vertical ownership as impractical. The owner has exclusive rights only to the immediate reaches of airspace—roughly the vertical space the owner can reasonably use and occupy for ordinary enjoyment. Beyond that, public navigable airspace and other policy considerations limit exclusivity.
Why was this a trespass case rather than nuisance?
Trespass protects the right to exclusive possession and is triggered by a tangible, physical invasion of land (including protected airspace). Nuisance addresses substantial and unreasonable interferences with use and enjoyment, typically through intangibles like noise, odor, or light. Because gun pellets and the discharge physically traversed the airspace, the invasion fit trespass.
Does it matter that the defendant never set foot on the plaintiff's land?
No. Trespass can occur without physical entry by the defendant's body. It is sufficient that the defendant intentionally caused a physical thing (here, shot and discharge) to enter the landowner's protected airspace without permission.
Are normal overflights by airplanes trespasses under Herrin?
Generally no. Flights at lawful altitudes in navigable airspace are privileged and not trespasses. Herrin protects only the immediate reaches necessary for land use. Later authority, including United States v. Causby, recognizes that low and frequent flights that directly and substantially interfere with the use of land may constitute a taking or a trespass-like invasion, but typical high-altitude flights are not actionable.
How does Herrin apply to drones?
Drones often operate in low-altitude airspace near or within a landowner's immediate reaches. Flights that cross into this space, especially at low heights and in ways that interfere with use and enjoyment, may constitute trespass or nuisance under Herrin's framework. Many jurisdictions are developing statutes and case law to define precise boundaries and remedies.
What damages are available for this kind of trespass?
Even absent proof of actual harm, nominal damages are available to vindicate the possessory right. If the invasion is willful or malicious, some jurisdictions permit punitive damages. If provable, actual damages for physical harm or lost use may also be recovered.
