The purpose of a multi party action is to bring together parties to litigation first so that they can share the time and costs of litigating issues in which they have an interest, rather than having to go over ground which the court has been over before with other litigants. Multi-party actions also allow parties to make representations in a case which might lead to findings of law which would bind that party under the doctrine of precedent, or to findings of fact which might bind that party as res judicata.
