Background

Attila Colar was charged with 44 federal offenses arising from an alleged scheme involving fraudulent Paycheck Protection Program loan applications, stolen identities, and efforts to obstruct the investigation. Representing himself with standby counsel, Colar maintained that law enforcement had targeted him because he is Black and Muslim.

After the jury was sworn, Juror 48, an alternate, told the district court that Colar’s defense had provoked a strong negative reaction. The juror said the defense lacked substance, characterized it as using discrimination as a scapegoat, and stated that he could not get those views out of his head. The court allowed him to remain without immediately determining whether he could be impartial. After a regular juror was excused several days into trial, the court questioned Juror 48, accepted his assurances that he was no longer biased, and seated him on the regular panel. The jury found Colar guilty on every count, and the court sentenced him to 204 months in prison and ordered more than $1 million in restitution.

The Court’s Holding

The Ninth Circuit held that Juror 48’s statements raised a colorable claim of actual bias. Once such a claim arose, the district court was required either to excuse the juror or promptly conduct an investigation reasonably calculated to determine whether he could remain impartial. His status as an alternate did not permit the court to postpone that inquiry because alternate jurors must satisfy the same impartiality requirements as regular jurors.

The district court abused its discretion by delaying meaningful inquiry until Juror 48 was needed on the regular panel and then conducting an inadequate colloquy after he had heard opening statements and testimony. Viewed as a whole, the record did not establish that the juror had unequivocally set aside his prejudgment of Colar’s defense or that the defense’s recurring race-and-religion theme would not trigger the same reaction again. Because doubts about impartiality must be resolved against the juror, the court also abused its discretion by failing to excuse him.

Juror 48’s participation in the guilty verdict deprived Colar of his Sixth Amendment right to an impartial jury. The error was structural and therefore not subject to harmless-error review. The panel vacated all 44 convictions, reversed the judgment, and remanded for a new trial. In a concurrently filed memorandum disposition, it affirmed the denial of Colar’s motion for acquittal, leaving retrial available.

Key Takeaways

  • A district court must promptly investigate whenever information raises a colorable claim that a juror is actually biased.
  • The duty to investigate applies equally to alternate jurors and cannot be deferred until an alternate is needed on the regular panel.
  • A juror’s general promise of impartiality is insufficient when the full record leaves doubt that the juror has abandoned prejudgment or can avoid renewed bias.
  • Participation by even one biased juror is structural error requiring reversal and a new trial.

Why It Matters

The decision clarifies that trial courts retain discretion over how to investigate suspected juror bias, but not whether to investigate a colorable claim. The inquiry must be prompt and proportionate to the seriousness of the statements, and the court must develop facts rather than assume an alternate juror poses no immediate constitutional concern.

The opinion also underscores the limits of juror rehabilitation. Courts must evaluate assurances of impartiality against the entire record, including whether the juror prejudged the defense and whether the same allegedly triggering issues will recur during trial.
