False Statements and Perjury Congressional Research Service

Federal courts, Congress, and federal agencies rely upon truthful information in order to make informed decisions. Federal law therefore proscribes providing the federal courts, Congress, or federal agencies with false information. The prohibition takes four forms: false statements; perjury in judicial proceedings; perjury in other contexts; and subornation of perjury. Section 1001 of Title 18 of the United States Code, the general false statement statute, outlaws material false statements in matters within the jurisdiction of a federal agency or department. It reaches false statements in federal court and grand jury sessions as well as congressional hearings and administrative matters but not the statements of advocates or parties in court proceedings. Under Section 1001, a statement is a crime if it is false, regardless of whether it is made under oath. In contrast, an oath is the hallmark of the three perjury statutes in Title 18. The oldest, Section 1621, condemns presenting material false statements under oath in federal official proceedings. Section 1623 of the same title prohibits presenting material false statements under oath in federal court proceedings, although it lacks some of Section 1621's traditional procedural features, such as a two-witness requirement. Subornation of perjury, barred in Section 1622, consists of inducing another to commit perjury. All four sections carry a penalty of imprisonment for not more than five years, although Section 1001 is punishable by imprisonment for not more than eight years when the offense involves terrorism or one of the various federal sex offenses. The same five-year maximum penalty attends the separate crime of conspiracy to commit any of the four substantive offenses. A defendant's false statements in the course of a federal criminal investigation or prosecution may also result in an enhanced sentence under the U. S. Sentencing Guidelines for the offense that was the subject of the investigation or prosecution.
