Examining Motions to Intervene and Complaints in Intervention in Legal Cases

General Definition

A motion to intervene or complaint in intervention is a legal action filed by a third party who is not initially involved in an ongoing lawsuit but has a vested interest in the outcome. The intervening party requests permission from the court to become a party to the case in order to protect their rights or interests. If granted, the intervener can actively participate in the proceedings, presenting their arguments, evidence, and legal claims alongside the original parties.

Overview of State Court Authorities

Arkansas

The Arkansas Court of Appeals has recognized that, “if the person seeking intervention will be left with his right to pursue his own independent remedy against the parties, regardless of the outcome of the pending case, then he has no interest that needs protecting by intervention of right.” (Turner v. Farnam (2003) 82 Ark. App. 489…)

It is also well settled that Ariz. R. Civ. P. 24(a)(2) “does not allow intervention of right where existing parties adequately represent the interest of the proposed intervenor.” (See Heritage Vill. II Homeowners Ass'n v. Norman (2019) 443 P.3d 964…)

Delaware

It is also well settled that "an attempt to intervene after final judgment is ordinarily looked upon with a jaundiced eye. The rationale which seems to underlie this general principle . . . is the assumption that allowing intervention after judgment will either (1) prejudice the rights of the existing parties to the litigation or (2) substantially interfere with the orderly processes of the court." (See See, e.g., McDonald v. E.J. Lavino Co. (1970) 430 F.2d 1065…)

New Jersey
