Whether the Ninth Circuit should clarify the abuse-of-discretion standard governing essentially factual applications of law to fact, including rulings on a motion for a new trial.
Holding
Yes. A district court abuses its discretion if it applies the wrong legal rule or, after identifying the correct rule, reaches a result that is illogical, implausible, or unsupported by inferences that may be drawn from the record.
Reasoning
The court treated the district court's application of the Rule 33 newly-discovered-evidence test as essentially factual. Under Ninth Circuit precedent, mixed questions are reviewed as factual when they turn on the trial court's assessment of particular events, credibility, motive, intent, or other matters rooted in trial-level factfinding, rather than on abstract legal values.
Supreme Court precedent establishes that an erroneous legal rule is necessarily an abuse of discretion. Thus, the first step is de novo review of whether the district court identified the correct legal standard governing the requested relief.
The second step reconciles the familiar formulations of clear-error review. An appellate court may not simply replace the trial court's permissible view of the evidence with its own, but neither must it uphold a finding that is illogical, implausible, or unsupported by record-based inferences. Drawing on Anderson v. City of Bessemer City, the court adopted those three objective criteria as the measure of deference.
The resulting test is especially appropriate for new-trial decisions. The trial judge observed the evidence and trial context firsthand, and the authority to grant a new trial is committed largely to that judge's discretion.
