How to use the petty offense checker
Korea has a summary trial procedure for minor cases capped at a fine of 200,000 won. The closest federal analogue is the petty offense. 18 U.S.C. 19 defines it as a Class B misdemeanor, a Class C misdemeanor or an infraction for which the maximum fine is no more than the amount in 18 U.S.C. 3571(b)(7) or (c)(7), which is $5,000 for an individual and $10,000 for an organization.
Classes come from 18 U.S.C. 3559(a) and depend on the maximum authorized term: more than one year is a felony, six months to one year is a Class A misdemeanor, thirty days to six months is Class B, five to thirty days is Class C, and five days or less is an infraction. Petty offenses are normally tried before a magistrate judge under 18 U.S.C. 3401 and Fed. R. Crim. P. 58, and there is usually no jury because the Supreme Court treats offenses carrying six months or less as presumptively petty in Blanton v. City of North Las Vegas, 489 U.S. 538 (1989). A defendant may appeal to a district judge within 14 days under Rule 58(g)(2)(B).
States use their own labels, often infraction, violation or summary offense, with separate thresholds. Figures reflect federal law as of September 2026. This checker is for reference only and is not legal advice. Consult a licensed attorney about your specific situation.
Frequently asked questions
Usually not. Offenses carrying six months or less are presumptively petty, and courts have found no Sixth Amendment jury right unless additional penalties make the offense serious.
For petty offenses a magistrate judge may proceed without the defendant's consent. Other misdemeanors require consent under 18 U.S.C. 3401(b).
