Which concept describes including a necessary party who has a stake in the outcome in one lawsuit to avoid multiple suits?

• A. Class Action Suit
• B. Compulsory Joinder
• C. Interpleader
• D. Permissive Joinder

Answer: (B)

Compulsory joinder is the idea that a party who has a stake in the outcome and whose absence could impair their interests or leave the plaintiff exposed to multiple or inconsistent obligations must be brought into the lawsuit if feasible. This ensures that relief can be fully and fairly granted in one action and helps prevent multiple lawsuits over the same controversy. If joining that party isn’t feasible—due to jurisdictional or practical barriers—the court must decide whether the case can proceed without them or must be dismissed. This concept is distinct from other ideas: a class action involves many plaintiffs with similar claims suing together; interpleader deals with a stakeholder seeking to resolve competing claims to a common fund; permissive joinder allows parties to join, but is optional rather than mandatory.
