While trial courts generally have broad discretion on motions for class certification,
“appellate review of orders denying class certification differs from ordinary appellate review. Under ordinary appellate review, we do not address the trial court’s reasoning and consider only whether the result was correct. [Citation.] But when denying class certification, the trial court must state its reasons, and we must review those reasons for correctness. [Citation.]”
“The right result is an inadequate substitute for an incorrect process. Thus the appellate scrutiny should be on the reasons expressed by the trial court in the context of counsel’s arguments, not merely whether the trial court reached a result [that] can be justified by implication.”The Court remanded for the trial court to explain its reasons for denying the motion.
