Class action litigation aggregates many similar claims into a single proceeding. The mechanism allows efficient resolution of disputes affecting large numbers of people when individual suits would be impractical. For defendants, class certification transforms manageable individual exposure into potentially existential liability.
Rule 23 Requirements
Numerosity requires that the class be so numerous that joinder of all members is impracticable. No magic number exists. Classes of 40 members can be certified. The question is whether joinder is practically achievable.
Commonality requires questions of law or fact common to the class. After Wal-Mart v. Dukes, commonality demands common answers to common questions that will drive resolution.
Typicality requires that named plaintiffs’ claims be typical of class claims. Representatives need not have identical claims, but their claims must arise from the same conduct and legal theory.
Adequacy requires that representatives fairly and adequately protect class interests. Conflicts with absent class members, inadequate counsel, or lack of commitment to litigation can defeat adequacy.
Rule 23(b) Categories
Rule 23(b)(1) classes address situations where individual litigation would create inconsistent standards for the defendant or impair other class members’ ability to protect their interests. Limited fund cases and structural reform cases often proceed under (b)(1).
Rule 23(b)(2) classes seek injunctive or declaratory relief. Civil rights cases seeking policy changes typically certify under (b)(2). Class members generally cannot opt out.
Rule 23(b)(3) classes, the most common for damages actions, require predominance and superiority. Common questions must predominate over individual issues. Class treatment must be superior to other methods of adjudication.
Predominance is more demanding than commonality. Common issues must predominate throughout the litigation, not just at one stage. Individual damages calculations can defeat predominance.
Superiority considers manageability, interest in individual control, existing litigation, and desirability of concentrating litigation. Class treatment must be the best way to resolve the controversy.
Certification Battles
Class certification is often the most important ruling in class litigation. Certification creates settlement pressure regardless of merits.
Discovery before certification is increasingly common. Parties need information to address certification requirements. Courts balance need for information against discovery costs.
Expert testimony on certification issues is routine. Economists address damages calculation. Industry experts address market definition. Social scientists address commonality.
Daubert challenges to experts occur at certification. Courts must evaluate expert methodology. Unreliable expert opinions cannot support certification.
Appeals of certification decisions are available by permission. Rule 23(f) allows discretionary interlocutory appeal. Circuit courts have discretion to accept or reject.
Class Notice
Notice to class members is required in (b)(3) classes before settlement or judgment. Due process requires informing absent class members of the litigation.
Individual notice is required when class members can be identified through reasonable effort. Mailed notice to known addresses is standard.
Publication notice supplements individual notice and reaches unknown members. Newspaper advertisements, internet advertising, and other methods are used.
Notice content must explain the litigation, class definition, claims, and opt-out rights. Plain language accessible to class members is required.
Costs of notice are typically advanced by plaintiffs. Defendants may ultimately bear costs if plaintiffs prevail.
Opt-Out Rights
Opt-out allows class members to exclude themselves from (b)(3) classes. Opting out preserves individual claims.
Deadline for opt-out is specified in the notice. Missing the deadline results in class membership.
Strategic opt-out by sophisticated parties with large claims allows individual prosecution. Institutional investors often opt out to pursue separate litigation.
No opt-out exists in (b)(1) and (b)(2) classes. These classes bind all members without choice.
Settlement
Class settlement requires court approval. The court evaluates whether settlement is fair, reasonable, and adequate.
Settlement class actions certify classes only for settlement purposes. Parties negotiate resolution without litigating certification for trial.
Objectors can challenge proposed settlements. Class members unhappy with terms can object and appeal.
Fee awards to class counsel are part of settlement approval. Courts evaluate reasonableness of attorney compensation.
Cy pres distributions donate unclaimed settlement funds to charitable purposes. The practice is controversial when meaningful distribution to class members is possible.
Common Class Actions
Securities fraud class actions challenge false or misleading statements that affected stock prices. The Private Securities Litigation Reform Act imposes heightened requirements.
Antitrust class actions seek damages for price-fixing, monopolization, and other violations. Indirect purchaser standing varies by jurisdiction.
Consumer protection class actions challenge deceptive practices, false advertising, and unfair business practices. State law variations affect nationwide classes.
Employment class actions address wage and hour violations, discrimination, and ERISA claims. Misclassification and overtime violations generate substantial class litigation.
Product liability class actions aggregate claims arising from defective products. Variations in state law and individual causation often defeat certification.
For Service Members
Service members participate in class actions as class members, opt-outs, and sometimes as named plaintiffs.
SCRA class actions have addressed systematic violations by lenders, landlords, and others. Service members affected by widespread violations may benefit from class recovery.
Consumer class actions affecting service members include financial services, telecommunications, and product cases. Military consumers harmed by class-wide conduct recover through class mechanisms.
VA benefits class actions have challenged systemic failures in benefits processing. These cases often seek injunctive relief under (b)(2).
Employment class actions may include service members in their civilian jobs. USERRA class actions have addressed widespread violations.
Opt-out decisions require evaluating individual claim value against class recovery. Large individual claims may justify separate prosecution.
Notice to deployed service members presents practical challenges. Adequate notice methods must reach service members regardless of location.
SCRA protections may affect class litigation timing. Deployed service members may be entitled to stays of proceedings affecting their interests.
A military attorney helps service members evaluate class membership, opt-out decisions, and claims related to military-specific class actions.
