“Statute does not oust equitable remedy – Where courts of Chancery have existed separate and distinct from courts of law, the existence of an interpleader statute governing the proceeding in courts of law has been held not to oust or take away the concurrent jurisdiction of the court of Chancery. A court of equity if first resorted to would not refuse to entertain a bill of interpleader, although a court of law might have been resorted to on the facts stated. … Where courts of law and equity are fused, and equitable principles are followed in the consolidated court, the rule is clear that interpleader statutes are not at all to limit or affect the equitable jurisdiction of the court to entertain an interpleader suit or action. Such statutes merely furnish another special, cumulative and concurrent remedy, summary in its operation, and they do not alter the settled doctrines concerning interpleader. The statutory remedy is a mere substitution for the equitable remedy, in the kinds of actions to which it applies.”
