Dalia v. United States

The Supreme Court held that the Fourth Amendment did not prohibit per se a law enforcement officer’s covert entry into a private premises. The Fourth Amendment’s requirement is that such entry be reasonable. Although Title III of the Omnibus Crime Control and Safe Streets Act did not refer explicitly to covert entry, the language, structure, and history of the statute indicated that Congress had conferred power upon the courts to authorize covert entries for enforcement of the law. The Court stated that the Fourth Amendment does not require that an electronic surveillance order issued by a court under Title III include a specific authorization to enter covertly the premises described in the order.
