United States v. Mara
Argued November 6, 1972
Decided January 22, 1973
410 U.S. 19
Respondent, subpoenaed to furnish handwriting exemplars to enable a grand jury to determine whether he was the author of certain writings, was held in contempt after refusing compliance, the District Court having rejected respondent's contention that such compelled production would constitute an unreasonable search and seizure. The Court of Appeals reversed, holding that the Fourth Amendment applied and that the Government had to make a preliminary showing of reasonableness.
Held: The specific and narrowly drawn directive to furnish a handwriting specimen, which, like the compelled speech disclosure upheld in United States v. Dionisio, ante, p. 410 U. S. 1, involved production of physical characteristics, violated no legitimate Fourth Amendment interest. Pp. 410 U. S. 21-22.
454 F.2d 580, reversed and remanded.
