What are the Rule 23 prerequisites and Rule 23(b) types for class actions?

• A. Numerosity, commonality, typicality, and adequacy of representation.
• B. Standing, ripeness, mootness, and finality.
• C. Evidence, relevance, prejudice, and confusion.
• D. Consent, waiver, discovery, and procedure.

Answer: (A)

When assessing class action certification under Rule 23, the key elements to look for are the prerequisites that ensure a class action is workable and fair. The four prerequisites are numerosity (too many potential plaintiffs to join individually), commonality (shared questions of law or fact among class members), typicality (the representatives’ claims or defenses are typical of the class), and adequacy of representation (the named plaintiffs will fairly and adequately protect the class’s interests). The Rule 23(b) types describe how the relief is to be managed and when a class action is appropriate beyond these prerequisites, with the main categories focusing on preventing inconsistent judgments or prejudice (b)(1), actions seeking injunctive or declaratory relief (b)(2), and actions involving common questions where predominance and superiority are satisfied (b)(3). The other options reflect different doctrines or considerations (such as justiciability like standing or ripeness, or evidentiary concerns) that aren’t the Rule 23 prerequisites. So the best answer lists the four Rule 23(a) prerequisites.
