As per sub-clause (2), the Court can award interest, but without prejudice to the provisions of sub-section (1). Therefore, when there is a Rule or an Act or usage having force of law, Section 4 does not have any application. The Interest Act, 1978, cannot be construed to be one in conflict with the GCC. The conditions are binding in nature having force of law. Similarly, the Interest Act also will have to be taken as the one in operation without violating the provisions of the Arbitration Act. It is well settled that even a right created under the statute can be waived by agreement. Thus, the payment of interest having been waived by accepting the terms and conditions cannot be agitated for the first time before the Tribunal. After all, the role of the Tribunal is to adjudicate the right of the parties under the contract and in order to set at naught its provisions, the other decisions viz., CWHECHCIL (JV) v.
