In reviewing a trial court's findings, which standard applies to credibility determinations on appeal?

• A. They receive deference and are reviewed for clear error.
• B. They are reviewed de novo and given no deference.
• C. They are reviewed for plain error only if preserved.
• D. They are automatically reversed on credibility issues.

Answer: (A)

Credibility determinations are findings of fact, and on appeal the court must give deference to the trial court’s assessment and review those findings for clear error. This reflects that the judge or court that actually observed the witnesses is better positioned to judge their credibility, including demeanor and Ramon cues, and thus their credibility findings are not reweighed wholesale by an appellate panel. The clear-error standard means the appellate court will overturn only if the finding leaves the appellate court with a definite and firm conviction that a mistake was made based on the record.

If you tried to apply a de novo standard, you’d be allowing the appellate court to substitute its own judgment about who was credible, which conflicts with the familiar rule that credibility is a matter of fact. Plain error applies to certain trial-court missteps that affect substantial rights and aren’t required to be preserved, but it isn’t the general rule for reviewing credibility determinations. Automatic reversal for credibility issues also isn’t correct, because the default approach is deference and a check for clear error, not automatic reversal.
