Adams v. Maryland
Argued January 7, 1954
Decided March 8, 1954
347 U.S. 179
1. In response to a summons, petitioner appeared before a Senate Committee investigating crime. Answering without objection questions asked on behalf of the Committee, he confessed to having run a gambling business in Maryland.
Held: under 18 U.S.C. § 3486, his testimony before the Committee was inadmissible in his trial in a state court for a gambling offense, and his conviction based on such evidence is reversed. Pp. 347 U. S. 179-183.
(a) Petitioners failure to claim a constitutional privilege against self-incrimination did not deprive him of the statutory protection afforded by § 3486. Pp. 347 U. S. 180-181.
(b) Section 3486 applies to criminal proceedings in state courts, as well as federal courts. Pp. 347 U. S. 181-182.
2. As thus construed, § 3486 does not exceed the constitutional power of Congress. P. 347 U. S. 183.
202 Md. 455, 97 A.2d 281, reversed.
