What You Should Know about the Class Action Fairness Act and Class Action Defense

CAFA establishes federal jurisdiction when the class has more than 100 members, the aggregate amount in controversy exceeds five million dollars, and there is minimal diversity between the named plaintiff and the defendant. Most class actions involving consumer claims, securities disputes, or employment issues meet these thresholds, meaning they qualify for federal removal. Once removed to federal court, your case is subject to the Federal Rules of Civil Procedure, which differ significantly from New York state rules on discovery timing, motion practice, and class certification standards. The five-million-dollar threshold is notably low; even modest per-class-member claims can aggregate to exceed this amount when multiplied across thousands of participants. From a practitioner's perspective, this jurisdictional floor captures the vast majority of consumer and employment class actions filed in New York state courts, shifting them to the federal system almost automatically.

Yes, any defendant can remove a class action to federal district court if CAFA's jurisdictional requirements are satisfied, regardless of whether the state court had already assumed jurisdiction. The defendant does not need permission from the plaintiff or the state court; removal is a unilateral right. Once removal occurs, the case is governed by federal law and federal procedure, which may alter discovery scope, expert disclosure deadlines, and class certification standards. In practice, defendants routinely use CAFA removal as a strategic tool to shift litigation to a federal forum they perceive as more favorable to defense interests. The removal mechanism itself is not reversible by the plaintiff; the only remedy is a motion to remand, which succeeds only if the removing defendant failed to establish one of CAFA's jurisdictional elements or if a state law claim falls outside federal question jurisdiction.

Federal courts apply Rule 23 of the Federal Rules of Civil Procedure, which requires that the class be so numerous that joinder is impracticable, that common questions of law or fact predominate, that the named plaintiff's claims are typical of the class, and that the named plaintiff will fairly and adequately protect class interests. New York state courts, by contrast, have applied more flexible standards historically, sometimes permitting class certification in cases where federal courts would deny it. Federal judges also conduct more rigorous fact-finding at the certification stage, often requiring expert testimony and detailed analysis of whether individual issues will overwhelm common questions. This heightened scrutiny can make it more difficult for plaintiffs to achieve class certification in federal court, particularly in cases involving individualized damages calculations or reliance on consumer-specific facts. The practical effect is that some class actions survive in New York state court but fail to achieve certification if removed to federal court, effectively narrowing the scope of collective litigation.

CAFA imposes stricter requirements for class settlement approval and attorney fee awards than many state courts historically imposed. Federal judges must find that the settlement is fair, reasonable, and adequate, and they must scrutinize attorney fee requests to ensure they are proportionate to the benefit achieved and consistent with market rates for comparable work. CAFA also requires that notice of the settlement be sent to state attorneys general and the federal government, creating an additional layer of governmental review before final approval. This transparency mechanism can delay settlement finalization, but it also provides a safeguard against collusive agreements that undercompensate the class. Courts in the Southern District of New York and other federal venues have become increasingly skeptical of coupon settlements and agreements that provide minimal monetary benefit to class members while awarding substantial fees to counsel.

Defendants can challenge class certification on multiple grounds, including arguing that individual questions predominate, that the named plaintiff is not typical of the class, or that the proposed class is not ascertainable. Additionally, defendants can seek to narrow the class definition, challenge the adequacy of class counsel, and move for summary judgment on liability or damages before the class is even certified. Federal courts have developed robust case law on each of these issues, creating a more predictable framework for defense strategy than existed in state courts. A key advantage for defendants in federal court is the ability to conduct discovery on class certification issues simultaneously with merits discovery, allowing them to gather evidence about individual variations in consumer behavior or product use that may undermine the class theory.

Yes, even after removal, a defendant can challenge whether CAFA jurisdiction actually exists by arguing that the class does not exceed 100 members, that the amount in controversy falls below five million dollars, or that diversity is not minimal. These challenges are raised in a motion to remand and must be decided by the federal court. If the court finds that CAFA jurisdiction is lacking, the case is sent back to state court. However, this is a difficult burden for the plaintiff to carry because the court assumes that CAFA jurisdiction exists unless the plaintiff proves otherwise by clear and convincing evidence. In practice, motions to remand based on jurisdictional grounds rarely succeed because the five-million-dollar threshold is so low that most consumer and employment class actions easily satisfy it. The removal mechanism has proven to be a powerful tool for defendants to shift litigation away from state courts, and CAFA has been criticized by plaintiff advocates for making that shift nearly automatic in cases involving multiple class members and modest individual claims.

CAFA has lengthened the time required to achieve class certification because federal courts conduct more intensive fact-finding and expert scrutiny at the certification stage. This extended timeline increases litigation costs for both sides, which can discourage plaintiffs from pursuing marginal claims, but it also may reduce pressure on defendants to settle early. Federal discovery rules also permit broader and more expensive discovery than some state courts allow, further increasing the cost burden. For potential litigants, this means that class actions may take longer to resolve and that individual recovery amounts may be reduced by higher defense costs and attorney fees. The practical effect is that smaller individual claims are less likely to proceed as class actions under CAFA because the cost-benefit analysis becomes unfavorable; the class must be large enough and the per-member claim substantial enough to justify the expense of federal litigation.

Federal courts in the Southern District of New York and the Eastern District of New York have developed influential case law interpreting CAFA and applying Rule 23 certification standards to consumer, employment, and securities class actions. These courts have established rigorous requirements for demonstrating that common questions predominate and that individual issues are manageable through class procedures. Judges in these districts have also scrutinized settlement agreements carefully to ensure that they provide meaningful benefit to class members and do not improperly favor class counsel at the expense of the class. For potential litigants, this means that class actions filed in New York federal courts face a higher certification bar than may exist in other jurisdictions, but they also receive settlements that are subject to thorough judicial review. Understanding how these courts apply CAFA and Rule 23 is important for assessing the viability of a potential class claim.

Before proceeding with class action litigation, potential litigants should evaluate whether their claim meets CAFA's jurisdictional thresholds, assess the likelihood of class certification under federal standards, and consider whether the timeline and cost structure of federal litigation justify participation. Documenting the nature and scope of the alleged injury, gathering evidence about the number of affected consumers or employees, and calculating the aggregate damages claim are concrete steps that help establish whether CAFA jurisdiction exists and whether class certification is realistic. Additionally, understanding the differences between state and federal procedure, including discovery scope and settlement approval standards, allows potential litigants to anticipate the litigation trajectory and make informed decisions about whether to pursue class relief or individual claims.
