In law, a joinder is the joining of two or more legal issues together. Procedurally, a joinder allows multiple issues to be heard in one hearing or trial and is done when the issues or parties involved overlap sufficiently to make the process more efficient or more fair. It helps courts avoid hearing the same facts multiple times or seeing the same parties return to court separately for each of their legal disputes.
Rule 9 of order 1 lays down that no suit shall be defeated by reason of misjoinder or non-joinder of parties. In such cases, the court may deal with the matter in controversy as regards the rights and interests of the parties avtually before it. However, this rule does not apply to cases where there is a non-joinder of necessary party.
