§1519 Venue Is Limited to the District of Falsification, Not the District of the Investigation

Introduction

Abouammo v. United States (U.S. Supreme Court, June 11, 2026) resolves a recurring federal venue problem: when a statute criminalizes conduct undertaken with intent to affect an official proceeding or investigation, may the Government prosecute where the intended “effects” would be felt, or only where the defendant acted?

Petitioner Ahmad Abouammo, a former Twitter employee, moved from San Francisco to Seattle. When San Francisco-based FBI agents investigating unauthorized disclosures interviewed him in Seattle, he allegedly fabricated a consulting invoice on the spot upstairs in his home and emailed it to an agent. Prosecutors charged him in the Northern District of California under 18 U. S. C. §1519 for falsifying a document with intent to obstruct a federal investigation. Abouammo argued venue lay only in the Western District of Washington, where he created the invoice.

The key issue: whether §1519 permits venue (1) only where the falsification occurred, or (2) alternatively where the federal investigation was located because the falsification was intended to obstruct it.

Summary of the Opinion

Justice Kagan, writing for a unanimous Court, held that a defendant charged under §1519 must be tried in the district where the falsification occurred. Venue cannot be laid in a different district simply because the investigation the defendant intended to obstruct was based there.

The Court’s core move is doctrinal: venue turns on the location of the offense’s essential conduct elements. Under §1519, the only prohibited conduct is the act of falsifying (or altering, destroying, etc.) a document. The statute’s “intent to impede, obstruct, or influence” is a mens rea requirement that does not add a second “conduct” location, and §1519 does not require any actual obstructive effect. Because Abouammo created the false invoice in Seattle, venue lay in Washington.

Analysis

Precedents Cited

1) The “essential conduct elements” framework

  • United States v. Rodriguez-Moreno, 526 U. S. 275: The Court again treats Rodriguez-Moreno as the modern anchor for venue analysis where Congress has not supplied a specific venue rule. Venue is determined by identifying “the conduct constituting the offense” and locating where that conduct occurred.
    Influence here: The Ninth Circuit purported to apply Rodriguez-Moreno but expanded “conduct” to include intended effects. The Supreme Court uses Rodriguez-Moreno to reject that move and re-center the inquiry on acts the statute forbids.
  • United States v. Anderson, 328 U. S. 699: Cited for the traditional locus delicti principle—venue is determined from “the location of the act or acts constituting” the crime.
    Influence here: Reinforces the opinion’s insistence that venue is act-based rather than effects-based unless the statute’s elements make effects part of the actus reus.
  • United States v. Cabrales, 524 U. S. 1: Used to underscore that the Constitution “twice safeguards” venue and that some crimes point to a single proper district because their conduct occurs in only one place.
    Influence here: Helps normalize a single-district venue result even when the broader factual setting spans states.

2) Constitutional purpose and the anti-“remote prosecution” principle

  • United States v. Cores, 356 U. S. 405: Quoted for the “unfairness and hardship” of prosecutions in remote places.
    Influence here: Supplies the normative backdrop for resisting prosecutorial venue choices untethered to the defendant’s acts.
  • Smith v. United States, 599 U. S. 236: Cited (via the Declaration of Independence history) to stress the Founders’ concern with being “transport[ed] … beyond Seas to be tried.”
    Influence here: Situates the venue right as structural, not a technicality, supporting a stricter approach to multi-district theories.

3) Mens rea does not create venue

  • United States v. Johnson, 323 U. S. 273: The Court treats Johnson as closely analogous. Under the Federal Denture Act, the offense was complete where the denture was mailed, not where received, even though the mailing was done “for the purpose of” sending into another State.
    Influence here: Johnson supplies a direct rebuttal to the Ninth Circuit’s “contemplated effects” theory: purpose/intent to affect another jurisdiction does not relocate where the crime was committed when the conduct element is complete at the point of action.

4) The Court’s “discrete and narrow” venue method

  • Travis v. United States, 364 U. S. 631: Reiterated for the idea that venue holdings are “discrete” because they depend on the “nature of the [specific] crime charged.”
    Influence here: The Court uses Travis to frame today’s holding as statute-specific: §1519’s single conduct element yields a single conduct location.

5) Rejection of the Government’s conspiracy analogy

  • Whitfield v. United States, 543 U. S. 209: Cited in discussing conspiracy venue concepts (overt acts) invoked by the Government by analogy.
    Influence here: The Court distinguishes §1519 from conspiracy-like inchoate offenses because §1519 is a standalone completed crime upon falsification; it is not “a step toward” an identified object offense.

Other authorities and statutory references

  • United States v. Detroit Timber & Lumber Co., 200 U. S. 321 appears in the syllabus note about the non-binding nature of a syllabus; it does not drive the venue analysis.
  • 18 U. S. C. §3237(a) is acknowledged as Congress’s general multi-district offense statute, consistent with the concept that some crimes have conduct in more than one district. The Court’s point: §1519 is not such a crime on its elements.
  • The Court distinguishes statutes requiring actual obstruction, citing 18 U. S. C. §1512(c)(2), to show why effects might matter there but not under §1519.
  • The opinion expressly avoids addressing the separate venue scheme in 18 U. S. C. §1512(i), emphasizing that §1519 has no associated venue provision.

Legal Reasoning

  1. Constitutional baseline: Article III and the Sixth Amendment require trial where the crime was committed. The Court treats venue as a substantive constitutional safeguard, not merely a convenience rule.
  2. Identify the “conduct constituting the offense”: Under §1519, the forbidden act is falsifying (or altering, destroying, etc.) a record/document/tangible object. The offense is complete upon falsification with the requisite intent—no transmission, use, reliance, or success is required.
  3. Locate that conduct: Falsification occurred in Seattle, so venue lies in the Western District of Washington.
  4. Reject “effects-based conduct”: The Ninth Circuit treated “contemplated effects” as part of “essential conduct.” The Supreme Court responds that effects are not elements of §1519’s actus reus; the statute does not require any actual obstruction. Therefore, the investigation’s location cannot supply venue.
  5. Reject mens rea as venue-generating: The Court states it has “never looked to” mens rea elements to determine venue and explains why that would be illogical here: a knowing or intent-laden falsification occurs in the same place as the physical falsification.
  6. Reject “inchoate offense” reframing: The Government’s effort to tether §1519 venue to some “ultimate” obstruction crime fails because §1519 is independent and can be violated without any further step toward another offense (e.g., falsify and put it in a drawer).

Impact

  • Constrains prosecutorial forum choice in §1519 cases: The Government must bring §1519 charges where the falsification (or alteration/destruction/etc.) occurred, even if investigators, agencies, or grand juries are located elsewhere.
  • Clarifies mens rea’s limited role in venue: Courts may be less receptive to arguments that an “intent to affect” a distant district converts that district into a proper venue when the statute does not make the effect an element.
  • Encourages charge selection and structuring: Where venue in the investigation’s district is strategically important, prosecutors may rely on other statutes with different elements (including actual obstruction provisions) or statutes with explicit venue provisions—though the opinion expressly does not construe 18 U. S. C. §1512(i).
  • Operational consequences for multi-state investigations: Document-tampering that occurs where a witness resides (or where counsel drafts materials) may force prosecutions into districts where the investigation is not centered, potentially increasing costs and complicating coordination.
  • Defense leverage: Defendants charged under §1519 gain a sharper tool for venue challenges, including pretrial motions to dismiss for improper venue when indicted in an effects-based forum.

Complex Concepts Simplified

Venue
The legally proper geographic place (federal judicial district) where a criminal trial may be held.
Locus delicti
The “place of the crime”—determined by where the offense’s elements, especially its prohibited acts, occurred.
Essential conduct elements
The actions the statute forbids and that the Government must prove the defendant did (as opposed to circumstances or intentions).
Mens rea
The required mental state (e.g., “knowingly,” “with intent”) accompanying the prohibited act.
Effects-based venue theory
An argument that venue lies where harm or impact is felt, even if the defendant’s prohibited act occurred elsewhere. The Court rejects that approach for §1519 because the statute does not require any actual impact.
Inchoate offense
A step toward another crime (classically attempt, conspiracy, solicitation). The Court holds §1519 is not inchoate because it is complete upon falsification and is not tethered to an object offense.
Standalone offense
A complete crime in itself, not dependent on completion (or even attempt) of some further offense.

Conclusion

Abouammo v. United States establishes a clear venue rule for 18 U. S. C. §1519: trial must occur where the document was falsified, not where an investigation is headquartered or where investigators experience the intended obstruction. The Court’s reasoning is firmly element-based: §1519’s only proscribed conduct is falsification, and its intent requirement does not convert contemplated effects into additional conduct elements. The decision strengthens constitutional venue protections by limiting remote prosecutions and provides a concrete, administrable rule for §1519 litigation going forward.
