The Class Action Fairness Act of 2005 dramatically expanded federal jurisdiction over class actions, but it contains mandatory exceptions designed to keep genuinely local controversies in state court. For plaintiffs' counsel handling consumer, property, and environmental class actions with a state-specific character, the local controversy and home state exceptions under 28 U.S.C. § 1332(d)(4) are among the most important tools available for resisting removal — and for strategically pleading the case in the first place.
CAFA's Jurisdictional Framework: § 1332(d)(2)
CAFA grants federal district courts original jurisdiction over any civil class action in which the matter in controversy exceeds $5,000,000 (aggregated across all class members) and there is "minimal diversity" — meaning any member of the plaintiff class is a citizen of a state different from any defendant. 28 U.S.C. § 1332(d)(2). This is a materially lower bar than traditional complete diversity, and it captures the vast majority of large-scale class actions that were previously confined to state court.
The burden allocation is settled: the defendant bears the burden of proving the § 1332(d)(2) jurisdictional prerequisites — amount in controversy and minimal diversity — on a notice of removal. Once those prerequisites are established, the burden shifts to the plaintiff to prove that a mandatory exception under § 1332(d)(4) applies. The Eleventh Circuit confirmed this allocation in Evans v. Walter Indus., Inc., 449 F.3d 1159, 1164 (11th Cir. 2006), stating that the only requirements of CAFA are in (d)(2), and the exceptions are for the plaintiff to prove.
The Home State Exception: § 1332(d)(4)(B)
The simpler of the two mandatory exceptions requires the court to decline jurisdiction where:
- Two-thirds or more of the members of all proposed plaintiff classes in the aggregate are citizens of the state in which the action was originally filed; and
- The primary defendants are also citizens of the state in which the action was originally filed.
28 U.S.C. § 1332(d)(4)(B). The Eleventh Circuit, consistent with most circuits, has treated the home state exception as a mandatory abstention doctrine rather than a jurisdictional divesting provision. Hunter v. City of Montgomery, 2017 WL 2634162 (11th Cir. 2017) (affirming remand under home state exception). The distinction matters procedurally: if the court has subject matter jurisdiction under § 1332(d)(2), it must affirmatively exercise the decision to "decline" jurisdiction — jurisdiction is not automatically eliminated by the home state exception.
"Primary defendants." The most contested element of the home state exception is the identification of the "primary defendants." CAFA does not define the term. Courts have applied a functional test: which defendants are the ones from whom significant relief is primarily sought? The rationale for the exception is that state courts should retain controversies involving their own citizens as primary parties, not controversies that happen to include a nominal state defendant among a group of out-of-state targets. A corporate defendant incorporated and headquartered in the forum state, whose conduct is at the center of the class claims, is the prototypical "primary defendant." A parent company, a franchisor, or an insurer whose relationship to the forum is more attenuated may not qualify.
In Hunter, the Eleventh Circuit affirmed remand to Alabama state court in a class action against the City of Montgomery and a private company (PhotoEnforcement Partners) that administered a traffic camera program. The court's analysis of "primary defendant" focused on which entities bore the principal liability for the alleged conduct, not merely on citizenship.
Proving two-thirds citizenship. The plaintiff bears the burden of proof by a preponderance of the evidence. The Eleventh Circuit has held that general population statistics, census data, and surveys of class members' residences may be insufficient — plaintiffs need evidence that specifically establishes citizenship (domicile), not mere residence, for the required proportion of the class. This is a significant evidentiary challenge for plaintiffs who have not yet engaged in class-wide discovery at the remand stage. Strategies include: requesting limited jurisdictional discovery before the remand motion is decided; relying on zip-code data for claims with geographic concentration; and using tax records, motor vehicle registration data, or insurance policy addresses to approximate domicile.
The Local Controversy Exception: § 1332(d)(4)(A)
The local controversy exception is more demanding than the home state exception and requires the plaintiff to establish all of the following:
- Greater than two-thirds of the members of all proposed plaintiff classes in the aggregate are citizens of the state in which the action was originally filed;
- At least one defendant is a defendant:
- (aa) from whom significant relief is sought by members of the plaintiff class;
- (bb) whose alleged conduct forms a significant basis for the claims asserted by the proposed plaintiff class; and
- (cc) who is a citizen of the state in which the action was originally filed; and
- Principal injuries resulting from the alleged conduct or any related conduct of each defendant were incurred in the state in which the action was originally filed; and
- During the 3-year period preceding the filing of that class action, no other class action has been filed asserting the same or similar factual allegations against any of the defendants on behalf of the same or other persons.
28 U.S.C. § 1332(d)(4)(A).
The local controversy exception is narrower in two important respects. First, it requires satisfaction of a "significant" local defendant test under the three-subpart (aa)/(bb)/(cc) element — the forum-state defendant must be a genuinely important party to the litigation, not a nominal one. Second, the 3-year prior-action bar is categorical: if even one other class action was filed in the preceding three years alleging "the same or similar factual allegations" against the same defendants, the local controversy exception is unavailable. This prior-action bar has been interpreted expansively by some courts and has defeated local controversy exception arguments in cases arising from recurring corporate misconduct.
Practical significance. For plaintiffs seeking to maintain a hurricane property insurance class action in Florida state court, the local controversy exception may be unavailable if a prior federal class action or state class action (removed to federal court) alleged similar conduct against the same insurer within the prior three years. The home state exception does not include this prior-action bar and is therefore the more reliable tool when dealing with defendants who are Florida-domiciled primary insurers.
Eleventh Circuit Practice Notes
Burden and procedure. The Eleventh Circuit treats both § 1332(d)(4) exceptions as affirmative defenses for the plaintiff to prove. Evans v. Walter Indus., 449 F.3d at 1164–65. A plaintiff who does not raise the exception on a remand motion cannot expect the court to raise it sua sponte (though the Ninth Circuit has held courts may do so permissively). The motion to remand must be supported by evidence, not just allegations, of the citizenship composition of the proposed class.
Timing. CAFA does not specify a deadline for invoking the § 1332(d)(4) exceptions, and the Eleventh Circuit has not imposed a rigid timeliness rule. However, delay in raising the exception — particularly where it could have been raised promptly after removal — risks a waiver argument. Best practice is to move for remand within 30 days of removal and simultaneously serve limited jurisdictional discovery requests on the class-citizenship questions.
Aggregation of claims. Section 1332(d)(6) requires aggregation of all class members' claims to determine the $5 million amount in controversy. This aggregation is for the § 1332(d)(2) threshold only — for the § 1332(d)(4) exception analysis, citizenship is assessed separately, and even a very large aggregate claim does not defeat the exception if the citizenship and primary-defendant elements are met.
Pleading to Invoke or Defeat the Exceptions
Plaintiff's pleading strategy. Counsel seeking to maintain cases in state court should plead the class definition with geographic precision — ideally, limiting the class to residents of the forum state. Plead the primary defendants as forum-state citizens and allege with specificity that principal injuries occurred within the forum state. Identify the forum-state corporate defendant from whom significant relief is sought by all class members. If the prior-action bar may be implicated, research the defendant's litigation history before filing; if a prior class action was filed within three years, consider whether the local controversy exception is viable or whether the case should be pleaded to invoke the home state exception instead.
Defendant's removal strategy. Conversely, defendants seeking to remove should challenge the plaintiff's class definition as artificially limiting citizenship by geographic restriction, and argue that the putative forum-state defendant is not a "primary" defendant — for example, because the parent corporation or national insurer, domiciled out of state, is the real source of the alleged harm and the primary target of the litigation.
Open Questions
The Eleventh Circuit has not comprehensively defined what makes a defendant "primary" for purposes of § 1332(d)(4). The circuit split on whether the prior-action bar in the local controversy exception is to be interpreted narrowly (only identical claims) or broadly (similar factual allegations) continues to affect state-specific class actions in recurring-conduct scenarios. Practitioners in the Eleventh Circuit should monitor Evans progeny and any forthcoming Supreme Court review of circuit splits on the CAFA exceptions.
Conclusion
The CAFA local controversy and home state exceptions are not technicalities — they are congressionally designed limitations on federal court jurisdiction over genuinely local controversies. For plaintiffs' counsel, invoking them successfully requires evidentiary discipline at the remand stage, careful pleading of the class definition, and strategic selection of which defendants to name and emphasize. The exceptions reward preparation and punish improvisation.
