Perjury Charges: How to Fight a False Statement Accusation

Materiality is the element that perjury prosecutions most frequently fail to establish, and it is where experienced defense counsel focuses first.

A statement is material if it has the natural tendency to influence, or is capable of influencing, the decision of the tribunal on a matter before it. The statement does not need to have actually affected the outcome of the proceeding. It needs only to have been capable of doing so. Courts have found statements immaterial when they concerned collateral facts that had no bearing on any issue in dispute, when the proceeding had already reached a conclusion on the relevant point, or when the information was available from other sources and the false statement added nothing to the record.

Challenging materiality in a grand jury perjury case requires understanding what the grand jury was actually investigating and whether the false statement was relevant to that investigation. A statement made during a grand jury proceeding that touched on a subject the grand jury was not pursuing may be technically under oath but immaterial to any matter before the body. An attorney who handles grand jury investigations and perjury defense can map the false statement against the scope of the underlying investigation and build the argument that materiality was not established.

Grand jury perjury is the most common context in which perjury charges arise, and it carries distinct procedural features that affect both the prosecution and the defense.

Grand jury proceedings are secret. The target of the investigation does not see the questions other witnesses answered, does not know what documents the government obtained, and does not know how the grand jury characterized its investigation at the time the testimony was given. This information asymmetry means that a statement made in the grand jury can look materially false in hindsight even when the witness had no way of knowing it contradicted the government's evidence at the time.

Prosecutors use perjury charges arising from grand jury testimony as leverage in broader investigations. A witness who lies to the grand jury about a peripheral matter may face a perjury indictment designed to pressure them into cooperating on the underlying investigation rather than to punish the lie itself. Recognizing that dynamic is essential to building a defense strategy that addresses both the perjury charge and the underlying investigation that produced it. An attorney who handles white collar criminal defense matters can evaluate whether the perjury charge is a standalone prosecution or a tool in a larger enforcement strategy and respond accordingly.

Perjury charges often arise weeks or months after the statement was made, by which time the government has assembled corroborating evidence and mapped your statement against the full record of the proceeding. The earlier your attorney reviews what was said and in what context, the more complete the defense can be. Contact our criminal defense team today for a confidential evaluation.

Obstruction of justice and perjury charges are legally distinct but strategically intertwined, and the relationship between them determines how a defendant should respond to an investigation before charges are filed.

A false statement in a proceeding constitutes perjury under § 1621 or § 1623. The same false statement, if made with the corrupt intent to influence the outcome of a judicial proceeding, can also be charged as obstruction under § 1503. Prosecutors charge both because the obstruction count provides a higher sentencing ceiling and because the corrupt intent element of obstruction allows the government to introduce evidence of motive that might not be admissible in a standalone perjury trial.

Defense strategy on the obstruction count focuses on the intent element. A witness who made a false statement out of embarrassment, confusion, or self-protection rather than a calculated plan to derail a specific proceeding may be guilty of perjury but not of corruption-based obstruction. Separating the two theories and contesting the corrupt intent element independently can reduce a defendant's sentencing exposure even when the falsity of the statement cannot be disputed. An attorney who handles obstruction of justice and perjury defense cases can analyze the government's evidence on corrupt intent and build the argument that the conduct does not rise to the level of obstruction even if a false statement was made.

Federal perjury under 18 U.S.C. § 1621 carries a maximum sentence of five years in federal prison. Federal false declarations under 18 U.S.C. § 1623 carry the same maximum. Obstruction of justice under § 1503 carries a maximum of ten years, and obstruction of a specific proceeding under § 1512 carries a maximum of twenty years when the obstruction involves physical force or threats.

Sentencing under the U.S. Sentencing Guidelines is determined by the base offense level for perjury and obstruction, which starts at 14 under U.S.S.G. § 2J1.3, adjusted for the scope of harm caused to the underlying proceeding, the number of false statements made, and whether the defendant was a public official or held a position of trust. A defendant with no prior criminal record charged with a single count of perjury in a civil proceeding may face a guidelines range near the bottom of the sentencing table. A defendant charged with multiple counts arising from false testimony in a federal fraud investigation faces a materially higher range.

Sentencing advocacy in perjury cases focuses on establishing that the false statement caused minimal harm to the underlying proceeding, that the defendant played a limited role in any broader scheme, and that personal circumstances including employment history, family support, and absence of prior criminal conduct support a sentence at the low end of the applicable range or a non-custodial alternative.

Perjury and obstruction charges are often filed as part of a broader investigation where the government has already built its case. Cooperation windows close and grand jury matters move quickly. Contact our attorneys today before the government's next step forecloses your options.

Perjury is the willful making of a false statement under oath on a matter material to the proceeding in which it is made. Under 18 U.S.C. § 1621, the government must prove the statement was made under a legally valid oath, that it was objectively false, that the defendant knew it was false at the time, and that it was material to the proceeding. Failure to establish any one of these four elements is grounds for acquittal.

Section 1621 applies to false statements made under oath in any proceeding before a court, grand jury, or federal officer. Section 1623 applies specifically to false declarations made before a federal court or grand jury and carries a different evidentiary standard. Section 1623 does not require the two-witness rule and allows the recantation defense, while § 1621 does not. Which statute applies depends on the specific proceeding in which the statement was made.

No. Perjury requires willfulness, meaning the defendant must have known the statement was false at the time it was made. A statement made under a genuine but mistaken belief that it was accurate does not satisfy the willfulness element. The government must prove the defendant's subjective knowledge, not just the objective falsity of the statement. Establishing that a statement was made in good faith, or that the defendant had a reasonable basis for believing it was true, is a complete defense to the willfulness element.

The two-witness rule requires the government to prove the falsity of a statement in a perjury prosecution under § 1621 through either two witnesses or one witness plus independent corroborating evidence. A single witness's testimony, standing alone, is legally insufficient to establish the falsity of a statement regardless of how credible that witness is. This rule does not apply to § 1623 false declarations charges, which follow standard evidentiary rules.

No. The Supreme Court held in Bronston v. United States, 409 U.S. 352 (1973), that a literally true statement cannot be the basis for a perjury conviction even if it was intended to mislead. The responsibility for precise questioning falls on the examiner. A witness who gives a technically accurate but unresponsive answer has not committed perjury under federal law, though some states apply a broader standard that encompasses misleading true statements in certain contexts.

Subornation of perjury under 18 U.S.C. § 1622 is the crime of inducing or procuring another person to commit perjury. It carries the same maximum penalty as perjury itself. Prosecutors charge subornation when communications between the defendant and a witness suggest coordination of testimony before a proceeding. Email records, text messages, and recorded calls between the defendant and witnesses are the primary evidence base for subornation charges. An attorney who handles perjury defense cases can review those communications and identify whether the coordination alleged rises to the level of criminal inducement or reflects legitimate preparation of a witness for testimony.
