Dow Chemical Co. v. United States, 476 U.S. 227 (1986), was a United States Supreme Court case decided in 1986 dealing with the right to privacy and advanced technology of aerial surveillance.

Factual background and decision

The EPA used, without a warrant, a commercial aerial photographer to get photographs of a heavily guarded Dow facility that was, according to the petitioner, protected by the State Trade Secrecy Law. The decision: For purposes of aerial surveillance, the open areas of an industrial complex are more comparable to an "open field" in which an individual may not legitimately demand privacy.^[1] In the absence of a "reasonable expectation of privacy" the Fourth Amendment prohibiting unreasonable searches does not apply.
