Identifying an indispensable party

The indispensable party is often a prudential standing requirement. That is, while the parties currently involved in litigation have an actual case or controversy, judges will not proceed without the indispensable party. This avoids potential double litigation and possibly inequitable outcomes. In determining whether a party is indispensable, courts generally look to three factors:

  1. Will the missing party's interests be harmed in some direct way by the outcome of the case?
  2. Does the missing party have an interest which would cause another party to the case to be subjected to multiple obligations?
  3. Can the court provide complete relief to the plaintiff without the presence of the missing party?

In patent law, for example, a patent owner is an indispensable party to a patent infringement suit brought by an exclusive licensee against an alleged infringer. The patent owner's rights would be directly affected by a finding of invalidity or unenforceability of the patent claims. At the same time, if the patent owner is not a party to the case, the alleged infringer could be sued separately by the patent owner, and could end up having to pay two judgments for the same act of infringement.
