Whether a named plaintiff may appeal a denial of class certification after his individual substantive claim becomes moot.
Holding
Yes. A putative class action does not become moot merely because the named plaintiff's individual claim expires after the trial court has denied class certification.
Reasoning
Article III requires a live case or controversy, including a sufficient personal stake to ensure concrete adversarial presentation. Although Geraghty's own parole claim had expired upon his release, the underlying challenge to the parole guidelines remained live for prisoners still subject to those guidelines.
A class-action plaintiff presents two distinct matters for resolution: the substantive claim and the procedural claim that he may represent a class. The expiration of the substantive claim does not automatically eliminate the plaintiff's interest in obtaining review of an adverse certification ruling.
Prior cases established that a certified class may continue even after the named representative's personal claim becomes moot, and other cases allowed review of class-certification rulings after final judgment or satisfaction of the named plaintiffs' claims. These decisions reflect that Article III mootness doctrine is applied with attention to the practical role of class litigation rather than through a rigid focus on the timing of certification.
The certification issue remained concrete and sharply contested. Geraghty had suffered the alleged injury while his claim was live, continued to press the certification issue vigorously, and sought review of a ruling that, if erroneous, had itself prevented the action from surviving his release. Those circumstances adequately protected Article III's concern for adversarial litigation.
