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.
Whoever falsely makes, forges, counterfeits, or alters any letters patent granted or purporting to have been granted by the President of the United States; or
Whoever passes, utters, or publishes, or attempts to pass, utter, or publish as genuine, any such letters patent, knowing the same to be forged, counterfeited or falsely altered—
Shall be fined under this title or imprisoned not more than ten years, or both.
