United States v. Mara, 410 U.S. 19 (1973)

Facts

  • A federal grand jury in the Northern District of Illinois investigated thefts of interstate shipments.
  • Richard J. Mara was subpoenaed to appear before the grand jury and was informed he was a potential defendant.
  • The grand jury directed Mara, through a designated agent, to provide handwriting and printing exemplars on two occasions to compare with writings relevant to the investigation.
  • Mara refused each time.
  • The Government petitioned the district court to compel the exemplars, stating they were essential to the investigation and would be used only as comparison standards; an FBI agent submitted an in camera affidavit supporting the request.
  • The district court ordered compliance; after continued refusal, it held Mara in civil contempt and confined him until compliance or expiration of the grand jury term.
  • The Seventh Circuit reversed, requiring a preliminary, open-court adversary showing of Fourth Amendment “reasonableness” before enforcing such compulsion.

Issues

  1. Whether compelling a putative defendant to provide handwriting and printing exemplars pursuant to a grand jury directive constitutes an unreasonable search or seizure under the Fourth Amendment.
  2. Whether the Fourth Amendment requires a preliminary judicial showing of “reasonableness” in an adversary proceeding before enforcing a grand jury demand for handwriting exemplars.

Decision

  • The Supreme Court reversed the Seventh Circuit and remanded.
  • The Court held the directive to provide handwriting and printing exemplars violated no legitimate Fourth Amendment interest.
  • Because the exemplars involved physical characteristics regularly exposed to the public, the Government was not required to make a preliminary showing of reasonableness before enforcement.
  • The contempt order for refusal to comply was proper.
  • Compelled production of handwriting and printing exemplars for identification and comparison generally does not implicate a legitimate expectation of privacy under the Fourth Amendment.
  • A grand jury directive that is specific and narrowly drawn to obtain physical identifying characteristics exposed to public view does not require a prior, particularized judicial determination of Fourth Amendment “reasonableness.”
  • Courts may enforce compliance with such grand jury demands through contempt when a witness refuses to provide non-testimonial physical exemplars.

Conclusion

The Court held that a grand jury may compel handwriting and printing exemplars without a preliminary Fourth Amendment reasonableness showing because such exemplars disclose only publicly exposed physical characteristics and therefore do not invade a protected privacy interest; refusal to comply may be sanctioned by contempt.
