Legal Standard: The class must be "so numerous that joinder of all members is impracticable."
Assessment Checklist:
Scoring Guidance:
| Class Size | Assessment |
|---|---|
| 40+ members | Generally satisfies numerosity |
| 21-39 members | May satisfy; consider other factors |
| 20 or fewer | Difficult to establish |
Legal Standard: There must be "questions of law or fact common to the class."
Post-Wal-Mart v. Dukes Standard: The common question must be capable of generating a common answer that will "resolve an issue that is central to the validity of each one of the claims in one stroke."
Assessment Checklist:
Red Flags for Commonality:
Legal Standard: The claims of the representative parties must be "typical of the claims of the class."
Assessment Checklist:
Legal Standard: The representative parties must "fairly and adequately protect the interests of the class."
Part A: Adequacy of Class Representatives
Part B: Adequacy of Class Counsel
23(b)(1)(A): Individual actions would create risk of inconsistent standards for defendant. 23(b)(1)(B): Individual adjudications would impair other class members' interests (limited fund).
When to Use: Limited fund cases, shared resources, common property. Note: NO opt-out right.
Legal Standard: Defendant "has acted or refused to act on grounds that apply generally to the class."
Assessment Checklist:
When to Use: Civil rights cases, employment discrimination seeking policy changes. Note: Typically NO opt-out right.

### CLASS DEFINITION RECOMMENDATION
[Proposed class definition]
Strategies: Establish presumption of reliance; focus on objective materiality.
Strategies: Conduct choice-of-law analysis; consider subclasses; argue laws are similar.
Response: After Comcast v. Behrend, need damages model matching liability theory. But variation in damages alone doesn't defeat certification if liability is class-wide.
Strategies: Define class using objective criteria tied to defendant's records.
