What it's about
The Supreme Court overturned Colorado's ruling and sent the case back (reversed and remanded), holding that the rule must yield when a juror clearly says racial stereotypes or animus drove the guilty vote.
After his conviction, two jurors reported that another juror had made racially biased statements during deliberations.
Colorado's evidence rule generally kept jurors from describing deliberations as evidence to challenge a verdict.
Question presented
Whether a no-impeachment rule constitutionally may bar evidence of racial bias offered to prove a violation of the Sixth Amendment right to an impartial jury?
What the Court decided
Holding
Where a juror makes a clear statement indicating that he or she relied on racial stereotypes or animus to convict a criminal defend ant, the Sixth Amendment requires that the no-impeachment rule give way in order to permit the trial court to consider the evidence of the juror’s statement and any resulting denial of the jury trial guar antee. 350 P. 3d 287, reversed and remanded.
- Result
- Reversed
The Court's reasoning
The Court said the Sixth Amendment right to an impartial jury requires an exception to rules that bar juror testimony, so a trial court can consider a clear statement tying the guilty vote to racial stereotypes or hostility.
The vote
From the opinions
“Even if a criminal defendant whose constitutional rights are at stake has a critical need to obtain and introduce evidence of such statements, long-established rules stand in the way.”
What's next
The case returns to Colorado for courts there to apply the rule to the juror statements. The Supreme Court did not itself order a new trial.
