The Supreme Court held that under Sections 30 and 33 of the Arbitration Act, 1940, a successor arbitrator can validly conclude arbitration proceedings if the parties acquiesce to the change without objection. The petitioner, having participated in the proceedings with full knowledge of the successor's appointment, was precluded from challenging the award on grounds of natural justice. The Court affirmed the lower courts' decisions, emphasizing that unless there is a clear legal error or misstatement of facts, the award is not subject to interference.
