On July 27th, the Fifth Circuit addressed federal court diversity jurisdiction. Plaintiffs filed a state court complaint alleging that defendants violated state consumer protection laws and the Truth in Lending Act in the servicing and foreclosure of plaintiffs' home mortgage. Defendants removed the matter to federal court, where the TILA claims were dismissed. Declining to exercise supplemental jurisdiction, the federal district court remanded the state law claims. Defendants appealed the remand. Because defendants established that a defendant had been improperly joined, the Fifth Circuit held the trial court had original, mandatory diversity jurisdiction over the state law claims and erred in remanding the case.
