Supreme Court of the United States
410 U.S. 1 (1973)
Dionisio (defendant) was one of several individuals subpoenaed by a grand jury and ordered to provide a voice sample. Dionisio refused to provide a voice sample. The United States (plaintiff) filed a motion to compel compliance with the subpoena. Dionisio argued that compelled production of a voice sample violated his rights under the Fifth Amendment and Fourth Amendment. The district court ruled in favor of the United States and ordered Dionisio to provide a voice sample. Dionisio refused and the district court found him in contempt. Dionisio appealed the contempt order. The court of appeals concluded that the subpoenas constituted an unreasonable search and seizure and reversed the district court order. The United States petitioned the Supreme Court for review.
