For instance, the general position of the law that the issue of jurisdiction of a Court can be raised at any stage of the proceedings of a case, even for the first time at the appellate stage, is not applicable to arbitral proceedings before an arbitral Tribunal because the Act, in Section 12(3) has provided the stage at which a challenge to the jurisdiction of the arbitral Tribunal is to or may be raised by a party.
