The 9th Circuit made plain that the Fifth Amendment's guarantee against self-incrimination does not extend to shield the recipient of a grand-jury subpoena from having to produce documents the law requires that he keep. The case arose when the grand jury subpoenaed M.H. for his foreign-banking records, which he was required to maintain pursuant to the Bank Secrecy Act. M.H. pleaded the Fifth, was held in contempt of the grand jury, and appealed. The 9th Circuit affirmed the contempt order, holding that the required-records doctrine rendered the Fifth Amendment inapplicable.
