What are the basic Rule 23 requirements for class certification?

• A. Numerosity, commonality, typicality, and adequacy of representation.
• B. Jurisdiction, standing, ripeness, and mootness.
• C. Notice, ascertainability, manageability, and superiority.
• D. Predominance, superiority, and commonality.

Answer: (A)

The main concept tested is the four core prerequisites for certifying a class under Rule 23: numerosity, commonality, typicality, and adequacy of representation. Numerosity means there are so many potential class members that joinder in a single lawsuit isn’t practical. Commonality requires questions of law or fact to be shared by the class. Typicality ensures the named plaintiffs’ claims are representative of the class’s claims, so their interests align with the class. Adequacy means the representatives will fairly and adequately protect the class’s interests and that the counsel is capable and conflict-free. Together, these show that a class action can be managed as a coherent group with a representative capable of safeguarding the class’s rights. The other options mix concepts from different areas: jurisdiction, standing, ripeness, and mootness concern who may sue and when the dispute is ripe for review; predominance (along with superiority) is part of the Rule 23(b) framework but depends on meeting the basic prerequisites above; and factors like notice, ascertainability, and manageability relate to practical aspects of class actions but are not the fundamental four prerequisites.
