Obstruction of Justice in Federal Cases
How Obstruction Charges Arise
The federal obstruction charge is, in most cases, the charge the defendant manufactured after the investigation began. Not before. The original conduct, the fraud or the false filing or the unreported income, generates the investigation. The obstruction generates a second crime with its own sentencing exposure, and in a considerable number of cases, the obstruction carries a heavier consequence than whatever conduct drew the government’s attention in the first place. A person learns they are under investigation. They react. The reaction becomes the case.
The pattern recurs across districts and across decades. Arthur Andersen did not collapse because of securities fraud. The accounting firm’s conviction for obstruction, later reversed by a unanimous Supreme Court in 2005, destroyed the partnership before the reversal could arrive. The reversal saved the legal record. It did not save the firm. Martha Stewart did not serve time for insider trading; she served time for the statements she made about it. The government could not prove the underlying securities violation. It did not need to. The cover was its own crime, and the crime produced its own sentence.
This architecture is what federal prosecutors rely upon, and it operates with the kind of consistency that should concern anyone who receives a target letter or a visit from an agent on a Tuesday afternoon.
What feels like self-preservation can constitute a separate federal offense.
The Statutory Framework
Chapter 73 of Title 18 contains the principal obstruction statutes, and the range of conduct they address is broader than most people assume before their first conversation with a defense attorney.
Section 1503 is the oldest of the major provisions. It prohibits corrupt interference with pending judicial proceedings. It reaches conduct directed at jurors, court officers, and the proceedings themselves. Its scope was intended to be limited to matters already before a court.
Section 1512 addresses witness tampering. The statute prohibits intimidating, threatening, or corruptly persuading any person in connection with an official proceeding, and the word “corruptly” is performing substantial work in that sentence, work the courts have spent decades trying to define with precision. Encouraging a witness to “remember things differently” can constitute a violation. Suggesting that someone “not say too much” when speaking with the FBI can constitute a violation. The line between permissible communication and criminal persuasion is thinner than the statute’s text suggests. Section 1512 does not require that a formal proceeding be underway at the time of the obstructive act. The anticipation of a proceeding is sufficient.
Section 1519, enacted as part of the Sarbanes-Oxley Act of 2002, criminalizes the knowing alteration, destruction, or falsification of records with the intent to impede any federal investigation. The phrase “in contemplation of” gives this provision its distinctive reach: a defendant who destroys documents before any subpoena has been issued, before any formal proceeding has commenced, has potentially violated Section 1519 if the destruction was motivated by intent to prevent those records from reaching federal authorities. Congress drafted this provision to close the gap that the Arthur Andersen prosecution had exposed, and courts have since applied it to conduct well beyond the corporate fraud context that prompted its passage.
Section 1001, which prohibits false statements to federal agents, sits adjacent to the obstruction statutes and frequently operates as one in practice. It does not require that the false statement be made under oath. It does not require a signed document. A conversation in a living room, an answer given to an FBI agent at the front door, is enough.
The combined effect of these provisions is a statutory architecture that reaches backward in time, outward in scope, and forward in consequence.
Fischer v. United States and the Limits of Section 1512(c)(2)
The Supreme Court’s 2024 decision in Fischer v. United States narrowed one of these provisions in a manner that practitioners are still absorbing.
Section 1512(c)(2) prohibits anyone who “otherwise obstructs, influences, or impedes any official proceeding.” The government had applied this subsection to individuals who participated in the breach of the Capitol on January 6, 2021, on the theory that disrupting the congressional certification proceeding constituted obstruction. In a six to three decision authored by Chief Justice Roberts, the Court held that the statute requires the government to establish that the defendant impaired the availability or integrity of records, documents, objects, or other things used in the official proceeding. The Court tethered subsection (c)(2) to subsection (c)(1), which addresses evidence tampering. Reading the “otherwise” clause as a limitless catchall, the majority reasoned, would render the careful distinctions elsewhere in Section 1512 superfluous.
Justice Jackson, in concurrence, observed that those who attempted to disrupt the peaceful transfer of power inflicted a wound on the nation, but that the question before the Court was narrower than the conduct that prompted it. Justice Barrett, dissenting (and joined by Justices Sotomayor and Kagan), argued that the text of the statute was broad but not vague, and that the majority’s construction required the Court to find “any way to narrow the reach” of the law.
Whether the decision represents a principled reading of statutory text or an unwarranted constriction of prosecutorial reach depends on which of the six opinions one finds persuasive. I am less confident than many commentators that the question is settled, particularly given how little guidance Fischer offers to the lower courts now tasked with applying the narrowed standard. The implications extend well beyond the prosecutions that prompted the case.
The Quiet Statute
Section 1001 deserves separate attention because it is the provision most likely to affect a person who did not commit the offense the government is investigating.
Federal agents conducting interviews do not always announce the consequences of dishonesty. A person who denies involvement, who minimizes a role, who provides an inaccurate account of events in a conversation the person did not initiate and did not realize was being recorded in an agent’s notebook, can face prosecution under this section. The Supreme Court eliminated the protection of the “exculpatory no” in Brogan v. United States in 1998, confirming that even a bare denial of wrongdoing constitutes a false statement under the statute. Seven circuits had previously recognized the doctrine. The Court discarded it in a single term.
We counsel clients on this point before they have spoken to anyone, and the advice is not complicated: silence is a constitutional right; a false statement is a felony. The distance between those two positions is a single sentence, spoken to the wrong person at the wrong time. Most people who contact this firm about obstruction exposure did not set out to obstruct anything; they set out to make a problem feel smaller. The statute does not distinguish between intentions.
Sentencing and the Compounding Effect
Obstruction charges appended to an existing indictment alter the sentencing calculus in ways that are, if we are being precise, disproportionate to the conduct involved.
The federal sentencing guidelines impose an upward adjustment for obstruction. The adjustment eliminates the acceptance of responsibility reduction and adds two offense levels. The result is that a defendant who obstructed and then entered a guilty plea faces a guidelines range higher than the defendant who did not obstruct. The obstruction did not help. It compounded the exposure it was designed to reduce.
This is the arithmetic that we present to every client who asks whether the government’s case can be managed through informal means. The numbers do not support that strategy. Three additional offense levels, in a fraud case where the base level is already high, can mean years of additional incarceration. The sentencing table does not operate on intuition.
Two offense levels from the obstruction adjustment, plus the loss of three levels for acceptance of responsibility: that is a five-level swing in something like forty percent of the cases we review, though the sample is not scientific. The swing translates to months or years, depending on the criminal history category.
Whether the guidelines account for the difference between a calculated destruction campaign and a panicked phone call to a business partner is a question the Sentencing Commission has not answered to anyone’s satisfaction.
What Silence Accomplishes
The most effective obstruction defense is the one that renders the charge impossible. That defense is silence, exercised before the first conversation with a federal agent, before the first document is touched, before the first reassuring call to a colleague who may already be cooperating.
We do not advise clients to obstruct nothing. We advise them to do nothing, which is a different instruction entirely. The right to remain silent is not a procedural formality invoked at the time of arrest. It is a substantive protection that prevents the creation of the very evidence the government would need to charge obstruction or false statements. Most defense attorneys will say the same thing. Where our approach differs is in the timing: we prefer to establish the framework for silence before the client has any contact with investigators, rather than after a conversation has already occurred and the question becomes what was said and whether it was accurate. The distinction sounds minor until one considers how many obstruction cases begin with a well-intentioned interview that the client believed was informal.
A consultation is where that analysis begins, and the first call costs nothing and presumes nothing.
