Perjury Under Federal Law: A Brief Overview

Book Synopsis: Although it now covers more than court proceedings, the definition of perjury has not changed a great deal otherwise since the framing of the Constitution. Blackstone described it as “a crime committed when a lawful oath is administered, in some judicial proceeding, to a person who swears wilfully, absolutely and falsely, in a matter material to the issue or point in question.” There are three general federal perjury laws. One, 18 U.S.C. 1621, outlaws presenting material false statements under oath in federal official proceedings. A second, 18 U.S.C. 1623, bars presenting material false statements under oath before or ancillary to federal court or grand jury proceedings. A third, 18 U.S.C. 1622 (subornation of perjury), prohibits inducing or procuring another to commit perjury in violation of either Section 1621 or Section 1623. In most cases, the courts abbreviate their description of the elements and state that to prove perjury under Section 1623 the government must establish that the defendant “(1) knowingly made a (2) false (3) material declaration (4) under oath (5) in a proceeding before or ancillary to any court or grand jury of the United States.” The courts generally favor the encapsulation from United States v. Dunnigan to describe the elements of Section 1621: “A witness testifying under oath or affirmation violates this section if she gives false testimony concerning a material matter with the willful intent to provide false testimony, rather than as a result of confusion, mistake, or faulty memory.” Section 1622 outlaws procuring or inducing another to commit perjury: “Whoever procures another to commit any perjury is guilty of subornation of perjury, and shall be fined under this title or imprisoned for not more than five years, or both,” 18 U.S.C. 1622. The false statement statute, 18 U.S.C. 1001, is closely akin to the perjury statutes. It outlaws false statements in any matter within the jurisdiction of a federal agency or department, a kind of perjury with oath prohibition. Moreover, regardless of the offense for which an individual is convicted, his sentence may be enhanced as a consequence of any obstruction of justice in the form of perjury or false statements for which he is responsible, if committed during the course of the investigation, prosecution, or sentencing for the offense of his conviction. The enhancement may result in an increase in his term of imprisonment by as much as four years.
