19 U.S.C. § 64 — Laws imposing fines applicable to persons acting under customs laws

This section extends existing penalty laws to a broader group of people. Normally, certain Acts impose fines, penalties, or other punishment on internal revenue officers or other Treasury Department officers (or officers of a bureau within Treasury) for offenses they commit. This section says those Acts also apply to all persons whomsoever who are employed, appointed, or acting under the authority of any customs law — as long as they are designated or acting as officers or deputies, or as persons who have custody or control of public money.
