The legal issue in Causby was whether the United States military's flying of large planes over Causby's farm in order to land and take-off from airbase nearby violated the Takings Clause of the Fifth Amendment. This is arguably a very different legal issue than whether flying aircraft (including UAVs) over private property may violate state or local trespassing, nuisance, harassment, stalking, or privacy laws.
The Fifth Amendment to the United States Constitution addresses criminal procedure and other aspects of the Constitution and applies to every level of the government, including federal, state, and local. The last clause of the Fifth Amendment is the so-called "Takings Clause", which limits the power of eminent domain by requiring "just compensation" be paid if private property is taken for public use:
No person shall be subject, except in cases of impeachment, to more than one punishment or trial for the same offense; nor shall be compelled to be a witness against himself; nor be deprived of life, liberty, or property, without due process of law; nor be obliged to relinquish his property, where it may be necessary for public use, without just compensation....
In
Causby, the court concluded that if the US wants to keep flying over Causby's property in furtherance of the war effort then okay so be it. But, given the extreme noise and disturbance the flights were causing to the property owner below, the US government would have to pay "just compensation" as it was depriving
Causby of the use and enjoyment of his property for the benefit of the public.
One type of aircraft that flew over Causby's property as low as 85 feet
