## Facts

- Esmail Yermian was hired by a defense contractor for work connected to the Department of Defense (DoD) and had to complete a DoD security questionnaire to obtain access to classified information.
- On the questionnaire, Yermian failed to disclose a prior mail fraud conviction and falsely claimed employment at two companies where he had not worked.
- Yermian signed a certification that his answers were true and correct to the best of his knowledge.
- Federal investigators discovered the falsity; Yermian admitted he knowingly provided false information.

## Issues

1. In a prosecution under 18 U.S.C. § 1001, must the government prove the defendant had actual knowledge that the false statement concerned a matter within the jurisdiction of a federal department or agency?

## Decision

- The Supreme Court reversed the court of appeals and reinstated the conviction.
- The Court held that § 1001 does not require proof that the defendant actually knew of federal agency jurisdiction.
- The Court read “knowingly and willfully” to modify the making of the false statement, not the jurisdictional phrase “within the jurisdiction of” a federal agency.
- The Court found the legislative history consistent with this reading and declined to add an extra mens rea element based on policy concerns about a “trap for the unwary.”

## Legal Principles

- Under 18 U.S.C. § 1001, the government must prove the defendant acted knowingly and willfully as to the falsity of the statement, but not as to the federal agency jurisdictional element.
- A jurisdictional element in a federal criminal statute generally does not carry an additional mens rea requirement unless Congress clearly provides otherwise.
- Courts will not add an unstated knowledge requirement to avoid perceived unfairness when the statutory text and history do not support it.

## Conclusion

A defendant may be convicted under 18 U.S.C. § 1001 for knowingly and willfully making false statements in a matter that is in fact within federal agency jurisdiction, even without proof the defendant knew of the federal connection.
