Brief Fact Summary. Respondents claim that their property was taken, within the meaning of the Fifth Amendment, by the regular army and navy aircraft flights over their house and chicken farm.
Synopsis of Rule of Law. The airspace is a public highway, but if the landowner is to have the full enjoyment of his land, he must have exclusive control over the immediate reaches of the enveloping atmosphere.
Issue. Has the Respondents’ property been taken within the meaning of the Fifth Amendment?
Held. Yes. But the case is remanded for a determination of the value of the easement and whether the easement was permanent or temporary.
The court noted the common law doctrine of ownership of land extending to the sky above the land. However, the court notes that an act of Congress had given the United States exclusive national sovereignty over the air space. The court noted that common sense made the common law doctrine inapplicable.
However, the court found that the common law doctrine did not control the present case. The United States had conceded in oral argument that if flights over the Respondents’ property rendered it uninhabitable then there would be a taking compensable under the Fifth Amendment. The measure of the value of the property taken is the owner’s loss, not the taker’s gain.
The airspace is a public highway. But it is obvious that if the landowner is to have the full enjoyment of his land, he must have exclusive control of the immediate reaches of the enveloping atmosphere. If this were not true then landowners could not build buildings, plant trees or run fences.
The airspace, apart from the immediate reaches above the land, is part of the public domain. The court does not set the precise limits of the line of demarcation. Flights over private land are not a taking, unless, like here, they are so low and frequent as to be a direct and immediate interference with the enjoyment of the land. The Court of Claims must, upon remand, determine the value of the easement and whether it is a temporary or permanent easement.
The landowner owns at least as much of the space above the ground as he can occupy or use in connection with the land.View Full Point of Law
