Latin. A pursuer must follow the forum, or court of the defender; that is, a pursuer raising an action against his debtor or obligant, must do so before the forum or court within whose jurisdiction the defender maybe at the time. The rationale of this rule is obvious; for if the defender be outwith the jurisdiction of the Court, before which he has been cited, any decree of that Court will be valueless, there being no way of enforcing it.
