Clearly Erroneous

Definition from Nolo’s Plain-English Law Dictionary

A standard of review in civil appellate proceedings. Under this standard, an appeals court must accept the lower court's findings of fact unless the appellate court is definitely and firmly convinced that a mistake has been made. In other words, it is not enough that the appellate court may have weighed the evidence and reached a different conclusion; the lower court's decision will only be reversed if it is implausible in light of all the evidence.
