Which Rule 12(b) addresses failure to join a necessary party?

• A. Rule 12(b)(2) Lack of Jurisdiction Over the Person
• B. Rule 12(b)(5) Insufficiency of Service of Process
• C. Rule 12(b)(4) Insufficiency of Process
• D. Rule 12(b)(7) Failure to Join a Necessary Party

Answer: (D)

Not including a party who is needed for the action is handled by the defense under Rule 12(b)(7). In North Carolina practice, a party may be considered necessary (often tied to Rule 19’s concepts of required or indispensable parties). If that party’s participation is essential for complete relief or their interests could be harmed by the action without their involvement, the court should require joinder. If joining them is not feasible, the case may be dismissed to avoid an unfair or incomplete adjudication. This is distinct from defenses addressing who may be sued or how service and process are conducted: lack of jurisdiction over the person (Rule 12(b)(2)), insufficiency of service of process (Rule 12(b)(5)), and insufficiency of the process itself (Rule 12(b)(4)).
