The Supreme Court addressed the issue of jurisdiction to extend an arbitrator's mandate, originally appointed by the High Court under Section 11(6) of the Arbitration Act. The Commercial Court had extended the mandate for six months, but the High Court ruled that only the High Court, not a subordinate court, has jurisdiction to extend the mandate. The Court reasoned that permitting different courts to intervene would disrupt the arbitration framework. Since the mandate had already expired by the time the petition was heard, the Court deemed the issue academic and made no order on substituting the arbitrator.
