The Xbox 360 is designed for gaming. Appellate litigation, gamers learned, is not.

On behalf of a putative class of purchasers of the Xbox 360, a group of gamers brought suit alleging a defect with the consoles. After the district court struck the class allegations, plaintiffs sought permission to appeal under Rule 23(f), which the Ninth Circuit denied. Rather than proceeding in litigation to final judgment, plaintiffs instead voluntarily dismissed their claims, with prejudice, while reserving a right to appeal the order striking class allegations. Plaintiffs then appealed the order under Section 1291. On appeal, the Ninth Circuit held that it had appellate jurisdiction and thus the case was still “sufficiently adverse” to be heard under §1291. The Supreme Court granted certiorari on the question of whether courts of appeals “have jurisdiction under §1291 and Article III . . . to review an order denying class certification (or, as here, an order striking class allegations) after the named plaintiffs have voluntarily dismissed their claims with prejudice.”
