## Facts

- Major David P. Schneider was accused of attempting to murder his wife, Debbie Schneider, by throwing her from an eighth-floor hotel balcony.
- Debbie Schneider survived the fall.
- Missouri prosecuted Schneider in state court for attempted murder arising from the balcony incident, and a jury acquitted him.
- Schneider testified at the state trial about the events surrounding his wife’s fall; the government later alleged that parts of that testimony were false.
- After the acquittal, the United States convened a general court-martial and charged Schneider with attempted murder under the UCMJ and with perjury based on his testimony in the state proceeding.
- Schneider moved to dismiss the perjury charge, arguing that the Fifth Amendment Double Jeopardy Clause (including issue-preclusion principles tied to an acquittal) barred the perjury prosecution because the state jury had returned a not-guilty verdict on attempted murder.
- The military judge denied the motion to dismiss.
- Schneider was convicted at court-martial of attempted murder and perjury and appealed.

## Issues

1. Whether the Double Jeopardy Clause barred the United States from prosecuting Schneider at court-martial for perjury based on testimony he gave in a prior state trial in which he was acquitted of attempted murder arising from the same incident.

## Decision

- The court affirmed the denial of Schneider’s motion to dismiss the perjury charge.
- The court held that the prior state-court acquittal did not, by itself, bar a later perjury prosecution based on Schneider’s state-trial testimony.
- The court reasoned that an acquittal on attempted murder does not necessarily determine that the accused’s testimony was truthful; the jury could have acquitted for reasons that did not resolve the truth or falsity of particular statements.
- The court upheld Schneider’s court-martial conviction for perjury (and did not treat the state acquittal as a constitutional bar to the court-martial proceedings).

## Legal Principles

- The Double Jeopardy Clause can incorporate issue-preclusion limits, but those limits apply only to matters that were actually and necessarily decided by the prior verdict.
- A general acquittal on a substantive charge (such as attempted murder) does not necessarily establish that the accused’s trial testimony about the underlying events was true.
- A perjury charge based on testimony given in an earlier case is not barred merely because the accused was acquitted in the earlier case; preclusion requires a clear showing that the acquittal necessarily rested on the truth of the specific statements alleged to be perjurious.

## Conclusion

United States v. Schneider held that Schneider’s state-court acquittal for attempted murder did not automatically preclude a subsequent court-martial prosecution for perjury based on his testimony in the state proceeding, because the not-guilty verdict did not necessarily decide that the challenged testimony was true.
