The U.S. Court of Appeals for the Third Circuit has clarified that neither the Class Action Fairness Act (CAFA) nor traditional diversity requirements can serve as a basis for federal jurisdiction over Magnuson-Moss Warranty Act (MMWA) class actions.

In the July 10 opinion, authored by Judge Patty Shwartz, the court consolidated four cases in which plaintiffs filed a single-count, putative class action complaint, where plaintiffs alleged that defendants either concealed written warranties prior to sale, or provided warranties that prohibited the use of third-party repair services or parts in violation of the MMWA.
