At the hearing of the appeals Counsel for Renusagar raised four contention: firsts, according to him an Arbitrator had no jurisdiction to decide the limits of his own jurisdiction and since in the case of international arbitration the jurisdiction of the Arbitrator had to be decided according to the law of the Forum where the question is raised in the instant case being the Indian Law) the jurisdiction of the Arbitrator, according to that law, had to be decided by the Court and not by the Arbitral Tribunal; secondly, the dispute sought to be referred related substantially to the claim for interest and that claim had to be (and was so stated in the Notice of intention to arbitrate) founded on the promissory notes which were independent contracts by themselves and therefore, the claim did not arise out of the suit Contract and hence could not be the subject of arbitration; thirdly the claim for compensatory interest was really a claim for damages arising out of tort and such a claim was in any case not covered by the suit Contract and fell outside the scope of the Arbitration Clause; and fourthly, in any event, Renusagar had made out a prima facie case by raising serious triable issues in the suit which should enable it to claim an injuction restraining the arbitration proceedings.
