Miller v. Eldridge

Summary

The Supreme Court of Kentucky held that the Court of Appeals improperly applied de novo review when evaluating the trial court's admission of expert testimony under Daubert. The court explained that factual findings concerning reliability are reviewed for clear error, while the ultimate admissibility decision and relevance determination are reviewed for abuse of discretion. It reversed the Court of Appeals and held that the trial court did not clearly err or abuse its discretion in admitting the expert's testimony.

Holdings

1. An appellate court reviews a trial court's factual findings concerning the reliability of expert testimony for clear error, not abuse of discretion or de novo review.
2. The trial court's discretionary decision to admit expert testimony, including whether it will assist the trier of fact, is reviewed for abuse of discretion.
3. The trial court's implicit finding that Taylor's testimony was reliable was supported by substantial evidence and was not clearly erroneous.
4. Taylor's testimony satisfied Daubert's relevance or 'fit' requirement because it addressed whether emboli could travel retrograde the distance alleged using established principles of physics and blood flow, even though it did not account for every complexity of the human body or every case-specific variable.
5. A trial court's failure to include express factual findings and legal conclusions in a Daubert ruling is not automatically grounds for reversal when the record supports the ruling and no request for findings was made.

Questions Presented

1. Whether the Kentucky Court of Appeals applied the proper standard of review to the trial court's Daubert ruling.
2. Whether the trial court's implicit finding that Taylor's expert testimony was reliable was clearly erroneous.
3. Whether the trial court abused its discretion by admitting Taylor's testimony as relevant and helpful under Daubert.
4. Whether the trial court's failure to make express Daubert findings required reversal.
