correctness of the particulars in the invoices. Once based on that a sum is due and payable and as admitted in the books of account of the Appellant/Petitioner, then, it is non receipt of that sum which is the foundation of the Award. Once that is the foundation, then, we do not see how the learned Judge or the Arbitrator can be faulted for rejecting the counter claim. That is rejected by assigning cogent and satisfactory reasons that the foundation for the counter claim is the same as that of the main claim. Once in the main claim the defence of the Appellant cannot succeed, then, they would not be able to obtain any relief in terms of their counter claim. There is, therefore, no perversity nor there is any error of law apparent on the face of the record, either in the Award or in its confirmation by the learned Single Judge.
