M.H. v. United States

Issue: (1) Whether the Required Records exception to the Fifth Amendment privilege against self-incrimination applies when an individual, without immunity, is compelled to respond to a subpoena where either the act of production or the admitted absence of required records has incriminating testimonial aspects; and (2) whether the Required Records exception to the Fifth Amendment privilege against self-incrimination applies to bank records under the Bank Secrecy Act, 31 U.S.C. § 5311, even though the Act is primarily a criminal statute, and requires the production of documents which are not customarily kept and have no public aspect.
