As per case facts, a loan default led to an ex parte arbitral award, which the appellant sought to execute. The executing court suo motu dismissed the execution application, holding ... the arbitrator's unilateral appointment rendered the award invalid and unenforceable due to lack of inherent jurisdiction. The question arose whether an executing court possesses the power to suo motu annul an arbitral award that had not been challenged by any party under the Arbitration and Conciliation Act. Finally, the High Court held that an executing court cannot go behind a decree unless it is inherently lacking jurisdiction, which was not properly established here. Since the award was final and binding, and no challenge was raised, the executing court erred in suo motu rejecting the execution application, restoring the matter for execution according to law.
