Background of the Case
The controversy arose from a Madhya Pradesh High Court ruling that had ordered substitution of an arbitrator under Section 29A (6) after the tribunal’s mandate expired under Section 29A (4). The High Court relied on earlier observations in Mohan Lal Fatehpuria v. Bharat Textiles, where substitution was seen as obligatory.
However, the Supreme Court bench comprising Justices Sanjay Kumar and Alok Aradhe set aside the High Court’s decision, holding that courts have discretion either to extend the mandate of the existing tribunal or to appoint a substitute arbitrator.
What Section 29A Provides
Section 29A was introduced to ensure timely completion of arbitration proceedings:
- Section 29A (1): Arbitration must be completed within 12 months from the date of reference.
- Section 29A (3): Parties may extend the period by six months.
- Section 29A (4): If the award is not made within this period, the arbitrator’s mandate terminates.
- Section 29A (5) & (6): Courts may extend the mandate and, if necessary, substitute the arbitrator.
The Supreme Court clarified that substitution is not automatic; it is a matter of judicial discretion depending on the facts of each case.
Key Points of the Judgment
- No Automatic Substitution: Termination of mandate does not mean the arbitrator must be replaced.
- Judicial Discretion: Courts can either extend the mandate or appoint a new arbitrator.
- Flexibility in Arbitration: The ruling prevents unnecessary disruption of proceedings when an arbitrator has already invested significant effort.
- Balancing Efficiency and Fairness: The judgment seeks to balance timely resolution with continuity of proceedings.
Implications for Arbitration Practice
This ruling is significant for businesses, lawyers, and arbitrators:
- Reduced Delays: Parties can avoid restarting proceedings with a new arbitrator.
- Cost Efficiency: Extending the mandate saves costs associated with substitution.
- Legal Certainty: The judgment resolves conflicting interpretations across High Courts.
- International Confidence: Clarification strengthens India’s position as an arbitration-friendly jurisdiction.

Related Developments
The Supreme Court has recently delivered other important rulings in arbitration law:
- In C. Velusamy vs. K Indhera (2026), the Court allowed retrospective extension of an arbitrator’s mandate even after an award was delivered late.
- In January 2026, the Court held that arbitrator ineligibility can be challenged at any stage, reinforcing safeguards against bias.
Together, these judgments reflect a broader judicial effort to refine India’s arbitration framework.
Conclusion
The Supreme Court’s ruling on Section 29A marks a turning point in arbitration law. By clarifying that substitution of arbitrators is not mandatory, the Court has provided flexibility and certainty to arbitration proceedings. This decision will likely reduce delays, enhance efficiency, and strengthen India’s reputation as a hub for dispute resolution.
