Summary

Makes it a crime to hide, lie about, remove, destroy, change, or otherwise falsify any documents, written answers, or spoken testimony that are asked for in a formal antitrust investigation. Trying to do any of those things or asking someone else to do them is also illegal. It is also illegal to dishonestly, by threats, by force, or by a threatening letter try to influence, block, or slow down a government department or agency proceeding, or a congressional inquiry or committee investigation. A person convicted can be fined, jailed up to 5 years, or both; if the offense involves international or domestic terrorism (as defined in section 2331), jail can be up to 8 years.

Historical and Revision Notes

Based on title 18, U.S.C., 1940 ed., § 241a, (Mar. 4, 1909, ch. 321, § 135a, as added Jan. 13, 1940, ch. 1, 54 Stat. 13; June 8, 1945, ch. 178, § 2, 59 Stat. 234). Word “agency” was substituted for the words “independent establishment, board, commission” in two instances to eliminate any possible ambiguity as to scope of section. (See definitive section 6 of this title.) Minor changes were made in phraseology.
