Miguel Angel Peña-Rodriguez, Petitioner v. Colorado.

Summary

The Supreme Court holds that the Sixth Amendment requires an exception to the no-impeachment rule when a juror makes a clear statement indicating reliance on racial stereotypes or animus to convict a defendant, allowing trial courts to consider such evidence. The Court reversed the Colorado Supreme Court and remanded the case. Justices Thomas and Alito dissent, arguing the Constitution does not provide a historical exception to juror testimony rules and warning that the decision threatens verdict finality and jury deliberation confidentiality.
