Source: Clearly Erroneous
The 'clearly erroneous' standard is a deferential standard of review used by appellate courts to review findings of fact made by a lower court. Under this standard, a finding is considered clearly erroneous only if the reviewing court has a firm conviction that a mistake has been made.
This standard is applied during appellate review of a district court's decision to grant or deny class certification. Courts use this standard when examining factual findings related to the requirements of Federal Rule of Civil Procedure 23, including commonality, typicality, and adequacy of representation.
The Third Circuit held that a district court's class certification decision is reviewed for clear error regarding factual findings underpinning the certification.
The Supreme Court emphasized the necessity for rigorous analysis of class certification prerequisites, noting that finding of fact can be scrutinized under the clearly erroneous standard.
The clearly erroneous standard is more deferential than the abuse of discretion standard, wherein an appellate court may overturn a decision if it finds it is outside the bounds of reasonableness. Unlike de novo review, which examines the issue without deference to the lower court's ruling, clearly erroneous only applies to factual determinations.
