Published May 9, 2026
## Class actions in District of Columbia **Class actions** allow one or more plaintiffs to sue on behalf of a larger group with similar claims. They're powerful tools for consumer + employment + securities cases — but face strict procedural requirements. ## Federal Rule 23 — the framework **Class certification requirements (4 prerequisites):** **1. Numerosity:** - Class so numerous that joinder impracticable - Typically 40+ members - No bright-line rule - Geographic dispersion considered **2. Commonality:** - Common questions of law / fact - Wal-Mart v. Dukes (2011) tightened standard - Common contention capable of classwide resolution - One "glue" question often enough **3. Typicality:** - Class representative claims typical of class - Same legal theory - Same factual pattern - Different damage amounts OK **4. Adequacy:** - Class representative will fairly + adequately protect class - No conflicts with class members - Competent counsel - Sufficient resources ## Plus one of three Rule 23(b) categories **Rule 23(b)(1):** - Risk of inconsistent adjudications - Or impair non-class members - Limited fund cases - Less common **Rule 23(b)(2):** - Injunctive relief class - Class-wide remedy - Civil rights cases - Limited monetary relief - Common in employment cases **Rule 23(b)(3) — "damages class" (most common):** - Common questions PREDOMINATE over individual - Class action SUPERIOR to other methods - Notice + opt-out rights to class - Most consumer class actions ## Predominance + superiority — the battle **Predominance:** - Common issues outweigh individual issues - Damages calculations often dispute - Comcast v. Behrend (2013) — damages must be susceptible to common proof **Superiority:** - Class action better than alternatives - Manageability concerns - Choice-of-law issues - Difficulties listed in Rule 23(b)(3)(D) ## Common types of class actions **Consumer class actions:** - False advertising - Defective products - Privacy violations (TCPA, BIPA, CCPA) - Data breaches - Pricing practices - Service quality **Employment class actions:** - Wage + hour violations - Discrimination patterns - ERISA claims - Misclassification - Off-the-clock work **Securities class actions:** - Federal securities laws - Misrepresentation in offerings - Insider trading impact - Specific procedures (PSLRA) - Lead plaintiff procedures **Antitrust class actions:** - Price-fixing - Monopolization - Indirect purchaser claims (Illinois Brick) - Federal + state laws **Civil rights class actions:** - Discrimination patterns - Constitutional violations - Voting rights - Disability access ## State class actions **${s.name} state-court class actions:** - Often parallel federal Rule 23 - Some states modified - ${s.name}-specific procedures - Different strategic considerations - State law differences in remedies ## Key procedural milestones **1. Complaint + class allegations:** - Define proposed class - Detail claims - Specific factual allegations - Class representatives identified **2. Discovery:** - Class certification discovery - Sometimes "phased" with merits - Damages model development - Class size + composition **3. Class certification motion:** - THE critical battle - Plaintiff's burden - Comprehensive briefing - Often determines outcome **4. Notice to class:** - After certification - Reasonable methods - Opt-out rights - Specific contents required **5. Settlement / trial:** - Settlement requires court approval - Fairness hearing - Class member objections - Trial rare in class actions ## Class Action Fairness Act (CAFA, 2005) **Federal jurisdiction expanded:** - Diversity jurisdiction expanded - $5M+ aggregate amount - Minimal diversity (1+ class member from different state than 1+ defendant) - 100+ class members - Most large class actions in federal court now **Effect:** - Forum-shopping reduced - More uniform treatment - Federal procedures + appeals - Specific notice + settlement requirements ## Settlement structures **Common class settlement features:** **Cash:** - Per-class-member payments - Tiered (based on damages) - Total settlement fund - Often most valuable to lawyers **Coupons / vouchers:** - Less valuable to class - CAFA scrutiny increased - Sometimes appropriate (small claims) **Injunctive relief:** - Practice changes - Often most valuable in employment / civil rights - Hard to value monetarily **Future benefits:** - Extended warranties - Discounts on future services - Less valuable than cash ## Attorney's fees **Common fee structures:** - Common-fund percentage (25-35% typical) - Lodestar (hourly × multiplier) - Court-approved - Specific scrutiny in CAFA cases - Class-member objections to fees ## Class members' rights **Opt-out:** - Right to exclude self from class (Rule 23(b)(3)) - Specific procedures + deadlines - Then can pursue individual case - Or do nothing (lose claims) **Object:** - Object to settlement - File written objections - Appear at fairness hearing - Court considers **Opt-in:** - For (b)(2) classes (injunctive) - For some specific statutes (FLSA collective) - Different mechanism ## Defenses for businesses **Common defenses:** **1.
