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.
(a) A party desiring to join another defendant to assert a claim relevant to the pending petition may do so as a matter of right by filing a petition for joinder. (b) A petition for joinder shall set forth the identity of employers and insurance carriers sought to be joined and the reasons for joining a particular employer or insurance carrier as well as the specific facts and the legal basis for the joinder.
