Ernest Joseph Tibbels, Petitioner/Cross-Respondent v. the People of the State of Colorado, Respondent/Cross-Petitioner

Summary

The court adopted a functional test for determining whether a trial court's statements about reasonable doubt lowered the prosecution's burden of proof: whether, considering the instructions as a whole and the trial record, there was a reasonable likelihood that the jury understood the statements to permit conviction under a standard below beyond a reasonable doubt. Applying that test, the court held that the trial court's home-purchase analogy involving a structurally significant crack in a foundation likely required an impermissibly high degree of doubt for acquittal and suggested that the defendant had to provide a reason to doubt guilt. The court therefore treated the error as structural and reversed the judgment below.
