No. 25-5146Jun 11, 2026Crime and Law EnforcementReversed

The question

Whether a defendant charged under 18 U.S.C. 1519 with falsifying a document to obstruct a federal investigation must be tried in the district where the falsification occurred, or may instead be tried in the district where the investigation was located.

Abouammo v. United States

What the Court decided

The Court held that a defendant charged under 18 U.S.C. 1519 must be tried in the district where the falsification occurred, and reversed the Ninth Circuit. The only prohibited act under the statute is falsifying a document with obstructive intent, so venue lies where that act took place, which here was Seattle. The statute's intent-to-obstruct provision is a mens rea element and does not shift venue to where the investigation sat.

The Court's opinion

Kagan, joined by Roberts, Thomas, Alito, Sotomayor, Gorsuch, Kavanaugh, Barrett, Jackson

The Constitution requires that a crime be tried where it was committed, and courts locate an offense by its essential conduct elements. The only conduct 18 U.S.C. 1519 proscribes is falsifying a document; once a person falsifies with the requisite intent, nothing more is needed to violate the law, so venue lies where the falsification occurred. The statute's intent-to-obstruct requirement is a mens rea element, and the Court has never looked to mens rea in fixing venue. A falsification with obstructive intent occurs in the same place as one without it, so the intent provision adds nothing to the conduct-focused analysis. The obstructive effects of the false invoice were not elements of the crime and cannot ground venue where the investigation sat.
