Public Service Commission of Utah v. Wycoff Co.

After the Utah Public Service Commission (plaintiff in the underlying state action) sought to require Wycoff (defendant) to obtain permission before transporting motion-picture film intrastate, Wycoff instead sued in federal court seeking a declaratory judgment that its film-transport activities were actually interstate commerce, exempting it from the Commission's permission requirement; the district court ruled the activity was intrastate and dismissed Wycoff's complaint, and the court of appeals reversed.
