Case Brief Summary & Legal Analysis
tl;dr: A defendant’s drug conviction was affirmed after the court clarified the different evidentiary standards for impeaching a defendant versus a government witness with a prior conviction under FRE 609(a)(1). The court also upheld the admission of a subsequent drug deal under FRE 404(b).
Legal Significance: This case provides a key interpretation of FRE 609(a)(1), articulating the more lenient standard for admitting prior convictions to impeach government witnesses (Rule 403 balancing) versus the stricter, pro-defendant standard for impeaching the accused.

Case Facts & Court Holding
Key Facts & Case Background
Defendant Clyde Tse was charged with distributing crack cocaine to a government informant, Stephen Williams, in a transaction that was not successfully recorded by law enforcement. At trial for this November transaction, the government’s case relied heavily on Williams’s testimony. To corroborate this testimony and rebut Tse’s defense that the meeting was innocent, the government introduced evidence of a subsequent, fully recorded drug transaction between Tse and Williams in February. Tse sought to impeach Williams by introducing his prior conviction for assault and battery on a police officer (ABPO). The district court, concerned about consistency with its potential ruling on Tse’s own prior ABPO conviction should he testify, excluded Williams’s conviction. The court appeared to apply the same standard to both, stating, “if it’s probative enough in one case, it has to be probative enough in the other.” The defense was, however, permitted to impeach Williams extensively on other grounds, including his history as a drug user, payments received as an informant, and prior false statements. Tse was convicted and appealed the evidentiary rulings.
Court Holding & Legal Precedent
