What is a reason for a court to allow intervention in a lawsuit?

Allowing intervention in a lawsuit is primarily based on the need to protect a non-party's interests that could be affected by the outcome of the case. The intervenor's interests might be at risk if they are not allowed to participate, as their legal rights could be adversely affected without their input or representation in the proceedings. This aligns with the principle of ensuring that all parties with a significant stake in the matter are given an opportunity to be heard, particularly when their involvement may help the court make a more informed decision.

Other options do not support the rationale for allowing intervention. For example, intending to delay proceedings does not justify intervention, as courts do not typically permit actions that disrupt the judicial process. If the original parties agree to withdraw, that situation generally renders intervention unnecessary because the case would no longer exist. Lastly, if the intervenor has no relevant connection to the case, this lack of connection would undermine the basis for intervention, as it would not demonstrate that their interests are sufficiently affected by the outcome of the litigation.
