petitioner has also been allowed to depose as a witness on behalf of the petitioner in the arbitral proceedings, which is not permissible. He further submits that the arbitrator has also displayed evident bias in the conduct of the arbitral proceedings. He also raises an objection as regards the nature and merits of the claims sought to be raised in arbitral proceedings, and further submits that the claims of the petitioner are also barred by limitation. 5. The above aspects highlighted by the learned counsel for the respondent has no bearing on the present application under Section 29A of the A&C Act. The issues raised by the learned counsel for the respondent pertain to the merits of the matter and the procedure being followed by the learned sole arbitrator. The respondent is at liberty to agitate these aspects by taking appropriate recourse as regards thereto, and as contemplated under the A&C Act, 1996. 6. The arbitral proceedings are admittedly at an advanced stage. An extension has already been granted by this Court on a previous occasion, in the same factual conspectus. In the circumstances, this Court finds no impediment in granting the requisite extension of time for completion of arbitral proceedings and making the award.
