[As regards the American decision in Becker Auto Radio case it may be stated, as pointed out by Counsel for G.E.C. that the point was not decided but the statement or observation was made on concession of the parties; and as regards statement of law at pages 91 92 in Russell on Arbitration it must be pointed out that the passage pressed into service by Counsel is merely a half portion of the statement of law but the fuller statement of law, as we shall indicate later, gives a different picture.] These authorities do not suggest that the arbitrator or umpire may not decide these questions even provisionally or tentatively, In other words, there is nothing in the general law of arbitration either English or Indian which prevents the arbitrators or an umpire from deciding questions of their own jurisdiction provisionally or tentatively and to proceed to make their awards on that basis, though it is clear that their provisional or tentative decision on questions of their own jurisdiction would be subject to the final determination by the Court and if the Court takes a contrary view their award will not be given effect to and in our view this is exactly the scheme of the Foreign Awards Act.
