What does "intervention" allow within the context of joinder?

Intervention allows a non-party to join a lawsuit, which is fundamental in providing an opportunity for individuals or entities who have a vested interest in the outcome of the litigation to become involved. This mechanism is particularly valuable when the non-party believes that their rights may be affected by the resolution of the case. By allowing this type of joinder, the legal system ensures that all pertinent parties are present in the litigation, promoting efficiency and fairness.

The ability to intervene is typically governed by rules that outline the appropriate conditions under which a non-party can join existing litigation, often requiring the non-party to possess an interest that may be impaired or impeded by the outcome. This principle enhances the procedural landscape of litigation by allowing all stakeholders a chance to present their perspectives and protect their interests.
