in any other case, imprisonment for not more than 10 years, a fine under this title, or both.
Based on title 18, U.S.C., 1940 ed., § 241 (Mar. 4, 1909, ch. 321, § 135, 35 Stat. 1113; June 8, 1945, ch. 178, § 1, 59 Stat. 234).
The phrase “other committing magistrate” was substituted for “officer acting as such commissioner” in order to clarify meaning.
1994—Pub. L. 103–322, § 330016(1)(K), which directed the substitution of “fined under this title” for “fined not more than $5,000”, could not be executed because the words “fined not more than $5,000” did not appear in text subsequent to amendment by Pub. L. 103–322, § 60016. See below.
Pub. L. 103–322, § 60016, designated existing provisions as subsec. (a), substituted “magistrate judge” for “commissioner” in two places and “punished as provided in subsection (b)” for “fined not more than $5,000 or imprisoned not more than five years, or both”, and added subsec. (b).
1982—Pub. L. 97–291, § 4(c)(1), substituted “or juror” for “, juror or witness” after “officer” in section catchline.
Pub. L. 97–291, § 4(c)(2), (3), substituted in text “grand” for “witness, in any court of the United States or before any United States commissioner or other committing magistrate, or any grand” after “or impede any”, and struck out “injures any party or witness in his person or property on account of his attending or having attended such court or examination before such officer, commissioner, or other committing magistrate, or on account of his testifying or having testified to any matter pending therein, or” after “discharge of his duty, or”.
Amendment by Pub. L. 97–291 effective Oct. 12, 1982, see section 9(a) of Pub. L. 97–291, set out as an Effective Date note under section 1512 of this title.
