Dahda v. United States

The case arose from the prosecution of Los Rovell Dahda and others for large-scale drug trafficking conspiracies. FBI wiretaps authorized by a federal judge in Kansas intercepted communications that occurred both inside and outside the judge’s district. The defendants moved to suppress the evidence, arguing that because Title III generally limits a judge’s wiretap order to the issuing district, the interceptions outside the territory violated the statute and required exclusion. The district court and the Tenth Circuit denied the motion. On May 14, 2018, the Supreme Court unanimously affirmed, holding that the territorial restriction is not a "core provision" necessary to the statute’s fundamental integrity, and therefore the statutory exclusionary rule does not automatically apply to such a violation.

The U.S. Supreme Court, in an 8-0 decision delivered by Justice Stephen Breyer, affirmed the lower courts. It held that suppression is not required for violations of the territorial limitation because such a violation does not undermine the core concerns that the statutory suppression remedy was designed to protect.

Whether the federal wiretap statute’s exclusionary rule, 18 U.S.C. § 2518(10)(a), requires suppression of intercepted communications when a wiretap order authorizes interception outside the issuing judge’s territorial jurisdiction in violation of 18 U.S.C. § 2518(3).

The ruling narrowed the scope of the statutory exclusionary remedy in federal wiretap cases. It clarified that not every technical violation of Title III triggers suppression, thereby limiting a common defense strategy used to challenge complex multi-jurisdictional drug and organized crime investigations. The decision emphasized a distinction between fundamental statutory guarantees and procedural territorial rules, giving prosecutors greater latitude in using intercepted evidence obtained under orders with geographical defects.
