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.
The summons announces a date by which the person or persons summoned must either appear in court, or respond in writing to the court or the opposing party or parties. The summons is the descendant of the writ of the common law. It replaces the former procedure in common-law countries by which the plaintiff actually had to ask the sheriff to arrest the defendant in order for the court to obtain personal jurisdiction in both criminal and civil actions.
