In an opinion rendered this week-Pena-Rodriguez v. Colorado-the Supreme Court carved out an important exception to a longstanding rule prohibiting jurors from being questioned about conduct during deliberations after a verdict has been rendered. The case involved a Colorado man who was convicted for sexually assaulting two teenage girls. The jury returned a verdict against him. After the trial, two jurors approached Mr. Pena-Rodriguez's criminal defense attorney and expressed concerns about another juror's racial comments during deliberations. Specifically, the juror went into a lengthy tirade about Mr. Pena-Rodriguez's Hispanic heritage, noting that he "believed the defendant was guilty because, in [the juror's] experience as an ex-law enforcement officer, Mexican men had a bravado that caused them to believe they could do whatever they wanted with women."
