Federal Perjury Defense Lawyers: 18 U.S.C. §§ 1621, 1622 & 1623

Federal perjury is a serious white-collar crime that occurs when an individual knowingly and willfully makes a false statement under oath regarding a material matter in a federal proceeding.

Federal law enforcement agencies like the FBI investigate perjury, and federal courts prosecute it; penalties can include up to 5 years in federal prison per count.

Prosecutors must prove beyond a reasonable doubt that the false statement was intentional, rather than the result of misremembering, confusion, or question ambiguity.

Legal Advisory: A false statement is only perjury if it is material—meaning it had the potential or capacity to influence the outcome of the underlying federal proceeding, investigation, or court decision.

The Three Federal Perjury Statutes

Federal law divides perjury into three primary statutes under Title 18 of the United States Code, depending on where and how the statement was made:

Federal Statute	Legal Name	Governing Context
18 U.S.C. § 1621	General Perjury	Applies broadly to oaths administered before any competent tribunal, officer, deposition, or federal document.
18 U.S.C. § 1622	Subornation of Perjury	Criminalizes procuring, persuading, or inducing another person to commit perjury under oath.
18 U.S.C. § 1623	False Declarations	Applies specifically to false statements made under oath before a Federal Grand Jury or Federal Court.

What Federal Prosecutors Must Prove to Convict

To secure a conviction for federal perjury, prosecutors from the U.S. Attorney's Office must prove four distinct legal elements beyond a reasonable doubt:

Statement Under Oath: The defendant took a legally binding oath or affirmation to tell the truth before a competent federal official, grand jury, court, or tribunal.
Objective Falsity: The statement was factually false when made, rather than being literally true, incomplete, or open to legitimate interpretation.
Materiality: The statement was relevant to the proceeding and could influence the grand jury, judge, agency, or tribunal.
Willfulness & Intent: The defendant knew the statement was false when making it and deliberately intended to deceive under oath.

Federal Perjury vs. False Statements (18 U.S.C. § 1001)

Federal prosecutors frequently stack perjury charges with or substitute them for 18 U.S.C. § 1001 (Making False Statements to Federal Agents):

Under Oath Requirement: Perjury under §§ 1621 or 1623 requires a formal, legally administered oath. Section 1001 does not require an oath—it applies to unsworn verbal or written statements given during informal interviews with FBI, IRS, or DEA agents.
Two-Witness Rule: Traditional perjury under § 1621 historically requires corroborating evidence (often two witnesses or one witness plus strong documentary evidence) to prove falsity, whereas § 1001 and § 1623 do not.

Key Legal Defenses Against Federal Perjury Charges

Defending against perjury charges requires challenging the prosecution's evidence regarding intent, language, and context:

Lack of Willful Intent: Proving the statement resulted from memory loss, honest mistake, factual confusion, or misinterpretation rather than intentional deceit.
Literal Truth Defense (Bronston Defense): Under the U.S. Supreme Court decision Bronston v. United States, an answer that is literally true—even if misleading or non-responsive—cannot legally constitute perjury.
Question Ambiguity: Demonstrating that the prosecutor's or investigator's original question was vague, compound, or ambiguous, making a definitive false answer impossible to establish.
Lack of Materiality: Showing the statement had no bearing on the core issues of the case and could not have influenced the tribunal or grand jury.
Statutory Recantation Defense (18 U.S.C. § 1623 Only): Admitting and correcting the false declaration during the same grand jury or court proceeding before the lie substantially affected the proceeding or was exposed.

Frequently Asked Questions (FAQs)

What is the maximum sentence for a federal perjury conviction?

A conviction under 18 U.S.C. §§ 1621, 1622, or 1623 carries up to 5 years in federal prison per count, supervised release, asset forfeiture, and fines of up to $250,000 for individuals.

How does a prosecutor prove a statement was "material" in a perjury case?

A statement is material if it had a natural tendency to influence, or was capable of influencing, the decision-making body (such as a grand jury or judge) handling the underlying proceeding, regardless of whether it actually succeeded in doing so.

Can you be charged with perjury for giving a literally true but misleading answer?

No. Under federal case law (Bronston v. United States), if your answer is literally true, it does not constitute perjury even if it was evasive, incomplete, or intended to mislead. The burden is on the questioner to ask precise questions.

What is statutory recantation under 18 U.S.C. § 1623?

Under § 1623(d), a defendant charged with false declarations before a federal court or grand jury can bar prosecution if they recant and correct their false statement during the same proceeding, provided the false statement has not already substantially affected the proceeding or been discovered.

What should you do if you receive a federal subpoena or are accused of lying under oath?

Do not attempt to speak with federal agents or prosecutors to explain the discrepancy. Immediately contact an experienced federal criminal defense lawyer who can review transcripts, evaluate materiality, and protect your constitutional rights.
