Motion for Class Certification
Produces a plaintiff-side FRCP 23 (or state equivalent) class certification motion grounded in case-file evidence and structured for rigorous judicial scrutiny.
Prerequisites
- Pleadings — complaint, answer, amended pleadings
- Discovery materials — interrogatories, document productions, RFAs, defendant's business records showing scope of conduct
- Expert reports — damages models, class-wide proof methodology, statistical analyses
- Deposition transcripts — named plaintiff(s), corporate designees, key witnesses
- Named plaintiff declaration — representative-role understanding, absence of conflicts
- Class counsel qualifications — CV/firm resume, prior class action experience, resources
Quick Start
- Review case materials and identify the uniform policy/practice at issue
- Draft a precise, administrable class definition tied to the liability theory
- Build Rule 23(a) arguments from discovery evidence
- Select and brief the applicable Rule 23(b) subsection
- Propose notice/administration plan and case management approach
- Preempt anticipated defense arguments with record citations
Core Workflow
1. Introduction (1–2 pages)
State defendant's specific misconduct, proposed class definition (temporal/geographic scope), approximate class size, common injury, and why joinder is impracticable.
2. Class Definition
The definition must:
- Track the liability theory (not merits outcomes)
- Be administratively manageable via objective criteria
- Specify dates corresponding to period of misconduct
- Match geographic scope to defendant's conduct and applicable law
- Require no individualized inquiry for membership
3. Rule 23(a) Prerequisites
Numerosity — Cite defendant's records, discovery data, or expert estimates. Address geographic dispersion and economic infeasibility of individual suits. For negative-value claims, show individual recovery < litigation costs.
Commonality — Apply Wal-Mart v. Dukes, 564 U.S. 338 (2011): identify common questions generating common answers. Focus on uniform policies, standardized contracts, common course of conduct. Distinguish substantial common questions from peripheral individual ones.
Typicality — Show named plaintiff suffered the same injury type through the same mechanism. Cite specific evidence. Address unique-defense arguments; distinguish damages quantum from liability theory.
Adequacy — Named plaintiff: case knowledge, commitment, no conflicts. Class counsel: prior class actions, results, judicial recognition, resources, co-counsel arrangements.
4. Rule 23(b) Analysis
Select the applicable subsection:
| Subsection | Standard | Key Proof |
|---|---|---|
| 23(b)(3) | Predominance + superiority | Common evidence per claim element; common damages methodology; superiority over alternatives |
| 23(b)(2) | Generally applicable conduct | Uniform injunctive/declaratory relief; address whether monetary claims are incidental |
| 23(b)(1)(A) | Inconsistent obligations risk | Separate actions would impose contradictory requirements |
| 23(b)(1)(B) | Impaired interests risk | Individual adjudications would practically dispose of absent members' claims |
For 23(b)(3) predominance, analyze element-by-element:
- Identify common proof method for each claim element
- Show common damages methodology — distinguish amount variation (acceptable) from methodology variation (problematic)
- Integrate expert findings on class-wide proof feasibility
- Address reliance/causation through presumptions or burden-shifting frameworks
For superiority: economics of individual claims vs. litigation costs, inconsistent-adjudication risk, concentration benefits, existing individual litigation.
5. Notice and Administration Plan
- Identification method from defendant's records
- Plain-language notice (lawsuit nature, class definition, opt-out rights, binding effect)
- Distribution methods (direct mail, email, publication, digital) with justification
- Cost estimates and allocation
- Claims administration process
6. Case Management Proposal
Address as applicable: liability/damages bifurcation, bellwether trials, statistical sampling, special master appointment, subclass structure.
7. Anticipatory Defense
| Defense Argument | Response Strategy |
|---|---|
| Individual issues predominate | Common proof resolves core liability; individual damages manageable post-certification |
| Class unmanageable | Propose specific tools: bifurcation, sampling, special master |
| Named plaintiff atypical/inadequate | Distinguish damages variation from liability-theory divergence |
| Class definition overbroad | Definition tracks liability theory with objective, administrable criteria |
| Ascertainability problems | Objective identification from defendant's own records |
| Subclass conflicts | Aligned interests on core liability; propose subclasses only if necessary |
8. Conclusion
Restate class definition, specify requested relief (certify class, appoint representative, appoint counsel), reference notice plan and case management procedures, request hearing if warranted.
Pitfalls and Checks
- Pinpoint citations required — every factual assertion must cite document name, page, paragraph, exhibit number. No document-level references.
- Jurisdiction-specific standards — circuits vary on predominance, ascertainability, and merits scrutiny. Identify and apply controlling precedent.
- Certification ≠ summary judgment — present enough merits evidence for certification without fully litigating the merits.
- FRE 702 / Daubert-Frye — ensure expert methodology survives reliability challenge under the applicable standard.
- Adverse authority — distinguish unfavorable cases as factually distinguishable, superseded, or inapposite. Never ignore them.
- Tone — professional, confident, evidence-driven. No hyperbole.
- Length — 25–50 pages depending on complexity and local rules.
