Mr. Shanti Bhushan, the learned counsel for the appel lant submits, inter alia, that the subject matter of the suit, namely, the question whether the agreement was void ab initio for mutual mistake was not arbitrable at all and the learned Courts below erred in holding so; that even assuming but not admitting that the subject matter was arbitrable, it having involved complicated questions of facts the court ought not to have exercised jurisdiction on the application under section 34 and in doing so it acted without jurisdiction and, assuming that the court had juris diction, it should have decided only after taking oral and documentary evidence and not merely on affidavits; that the agreement itself having been void ab initio due to mutual mistake the arbitration clause, namely, clause 18 of the charter party, also perished with it and there was no scope for arbitration at all and the learned 483 courts below erred in holding that all the contentions raised and allegations made in the suit were arbitrable under the arbitration clause; and that the agreement was void being violative of the conditions of the permission and for that matter the import licence and the provisions of the Import and Export Control Act.
