21.1 The learned Senior Counsel has placed heavy reliance upon the Reliance Cellulose case which lay down the preposition that Section 31(7) of the 1996 Act, sanctifies agreements between the parties and states that the moment the agreement says otherwise, no interest becomes payable right from the date of cause of action until the award is delivered. No doubt Clause 64.5 of the General Conditions of Contract stipulates that no interest shall be payable, where the Arbitral award is for the payment of money, on whole or in part of the money till the date on which the award was made. Unfortunately, despite the specific claim No.13 has been made by the first respondent/claimant, no defence has been raised to the said claim and the learned Arbitrator while dealing with the same in Issue No.17, has given the above said finding. Though award of pendente lite interest has been raised as a ground in O.P.No.77 of 2011, no arguments have been advanced on the said ground. In the light of the decision rendered in Susaka's case cited supra, it amounts to waiver and therefore, the appellants are precluded from raising the said plea as a ground in this appeal.
