How often courts cite this section
Court decisions citing this, by year.Markers show enactment, consequential amendments, and circuit splits over this section — watch for a citation surge after a change or a disagreement. The dip in the last several years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the most recent years, so recent citations are undercounted.
As used in this chapter—
(1) the terms “judge” or “judicial officer” mean, unless otherwise indicated, any United States magistrate judge, Federal district judge, and
(2) the term “offense” means any Federal criminal offense which is in violation of any Act of Congress and is triable by any court established by Act of Congress (other than a Class B or C misdemeanor or an infraction, or an offense triable by court-martial, military commission, provost court, or other military tribunal).
