As a preliminary matter, federal district courts must have subject matter jurisdiction over an action to issue an opinion. Absent evidence to the contrary, there is a “strong presumption” against federal court jurisdiction. See, e.g., Boghozian v. Jaguar Land Rover N. Am., LLC, Case No. CV 19-2729-JFW(PLAx), 2019 WL 1925491, at *1 (C.D. Cal. Apr. 29, 2019). Congress has outlined federal court jurisdiction through the enactment of federal statutes such as 28 U.S.C. § 1331 and § 1332, which allow federal district courts to exercise jurisdiction over cases involving, respectively, a federal question and cases where all plaintiffs are different citizens from all defendants. This article will focus on the uniqueness of diversity jurisdiction in the context of class action litigation.
Under 28 U.S.C. § 1332(a), parties generally must show complete diversity between plaintiffs and defendants. Under the Class Action Fairness Act (CAFA), however, minimal diversity is enough—i.e., at least one plaintiff and one defendant must be diverse citizens. 28 U.S.C. § 1332(d)(2). While Congress has set other limits on federal courts’ jurisdiction over class action cases, such as raising the amount-in-controversy requirement to $5,000,000 and requiring a class to include at least 100 members, 18 U.S.C. § 1332(d)(2), (d)(5)(B), minimal diversity under CAFA is not the only difference in class action citizenship for jurisdiction purposes.
In non-class action cases in which a plaintiff or defendant is a limited liability company, courts look to the citizenship of each of the company’s members to determine its citizenship. See, e.g., Rolling Greens MHP, L.P. v. Comcast SCH Holdings L.L.C., 374 F.3d 1020, 1022 (11th Cir. 2004). In the context of class actions, however, several courts have held that limited liability companies should be treated as “unincorporated associations” such that courts may determine the citizenship of limited liability companies by looking at the state under whose laws the company is organized and the state where the company has its principal place of business. See Ferrell v. Express Check Advance of SC LLC, 591 F.3d 698, 702 (4th Cir. 2010); but see Angiano v. Anheuser-Busch InBev Worldwide, Inc., 2021 WL 364641, at *2 (C.D. Cal. Feb. 2, 2021) (Minute Order).
