Intervention Motion

An Intervention Motion is a legal document filed by a non-party to a lawsuit, seeking to join the case as a party. The motion typically argues that the non-party has a legal interest in the subject matter of the lawsuit and that their interests are not adequately represented by the existing parties. The purpose of the motion is to allow the non-party to participate in the case and protect their interests, which may be affected by the outcome of the litigation. Intervention can be either permissive (at the discretion of the court) or of right (required by law or rule). The court will consider factors such as the timeliness of the motion, the potential prejudice to the existing parties, and the non-party’s interest in the case. If the motion is granted, the intervenor becomes a party to the case and may participate in discovery, motion practice, and trial. Intervention motions are an important tool for ensuring that all interested parties have a voice in the litigation process, particularly in cases involving public policy or broad societal interests.
