The underlying dispute involved allegations of breach of warranty and deceptive trade practices based on a sale of an allegedly defective car. The Fifth Circuit explained that the FAA, which governed the alleged arbitration agreement in the purchase contact, does not supply jurisdiction in the federal courts, that there was no federal question jurisdiction here, and that there was insufficient information in the record to show that diversity jurisdiction existed. The court ruled: “This Court is not satisfied, based on the record before it, that AutoNation does not share citizenship with the [plaintiffs]. For that reason, we VACATE the district court’s order and REMAND for a determination of subject matter jurisdiction. If diversity is not established, the district court must dismiss the parties’ suit.” Roman v. AutoNation Ford Gulf Freeway, Case No. 16-20047 (5th Cir. Oct. 13, 2016).
