Supreme Court Rules Arbitrator Mandate Ends After 18-Month Expiry Without Extension

In a significant ruling that reinforces the time-bound nature of arbitration proceedings in India, the Supreme Court has clarified the automatic termination of an arbitrator's mandate under Section 29A(4) of the Arbitration and Conciliation Act, 1996 (the Act). Delivered on December 10, 2025, in the case of Mohan Lal Fatehpuria v. M/S Bharat Textiles & Ors. (2025 INSC 1409), a Division Bench comprising Justices Alok Aradhe and Sanjay Kumar held that once the statutory 18-month period for delivering an arbitral award expires without an application for extension, the arbitrator becomes functus officio . The Court further emphasized the power under Section 29A(6) to substitute the arbitrator, allowing proceedings to resume from the stage previously reached. This decision comes amid ongoing concerns about delays in arbitration, a mechanism designed for speedy dispute resolution.

The judgment quashed a Delhi High Court order that had extended the original arbitrator's mandate by four months without substitution, appointing instead Justice Najmi Waziri (Retd.), a former Delhi High Court judge, as the new sole arbitrator. The proceedings must now conclude within six months. As the Court observed: "The substitution of a sole arbitrator is warranted when his mandate ceases to exist, to effectuate the object of the Act, which mandates expeditious resolution of the dispute."

This ruling arrives as lower courts grapple with similar issues in statutory arbitrations, highlighted by a concurrent Bombay High Court decision on December 9, 2025, in Shahapur Bhagar Food LLP v. The Land Acquisition Officer & Ors. , which affirmed the applicability of Section 29A timelines even in land acquisition disputes under the Maharashtra Highways Act, 1955.

Background and Factual Context

The Supreme Court case stems from a long-standing partnership dispute. In 1992, the appellants—a husband and wife—along with respondents 2 to 4, executed a partnership deed containing an arbitration clause. Respondent No. 1, M/S Bharat Textiles, was registered as a partnership firm in 2007. Disputes arose, leading the Delhi High Court on March 13, 2020, to appoint Advocate Anjum Javed as the sole arbitrator, with fees fixed per the Fourth Schedule of the Act.

The arbitrator entered reference on May 20, 2020, and issued directions for pleadings and administrative expenses. However, tensions emerged over fee demands, with respondents 2 and 3 challenging them under Sections 14 and 15 of the Act. The High Court dismissed these in January 2022, holding the arbitrator eligible and directing actual expense disclosures. Despite this, proceedings stalled. Pleadings completed by November 19, 2020 (adjusted for COVID-19 exclusions until February 28, 2022), required an award by February 28, 2023. No extension was sought, leading to mandate termination under Section 29A(4).

Appellants then petitioned under Section 29A(6) for substitution and extension, but the High Court on April 22, 2025, only extended time by four months, declining substitution. The Supreme Court, granting leave, overturned this, noting the arbitrator's mandate had lapsed.

In parallel, the Bombay High Court addressed delays in statutory arbitration under the Maharashtra Highways Act. In land acquisition disputes from 2019, petitioners invoked Section 19B(8), designating the Divisional Commissioner as arbitrator. Pleadings completed in May 2021, but proceedings dragged, with the state shuffling arbitrators between Konkan and Nashik divisions without progress. By December 2025, over four years had passed without hearings. Justice Somasekhar Sundaresan ruled Section 29A applicable "subject to" the Highways Act, but found no conflict, allowing substitution to prevent absurdity.

Legal Analysis: Decoding Section 29A of the Arbitration Act

Section 29A, inserted by the 2015 Amendment and refined in 2019, addresses chronic delays plaguing Indian arbitration. As remedial legislation applicable to pending proceedings (per Tata Sons Pvt. Ltd. v. Siva Industries & Holdings Ltd. , 2023), it mandates awards within 12 months of pleadings completion (extendable by parties to 18 months). Subsection (4) is pivotal: "If the award is not made within the period specified... the mandate of the arbitrator(s) shall terminate unless the Court... extended the period."

The Supreme Court reconciled this with Rohan Builders (India) Pvt. Ltd. v. Berger Paints India Ltd. (2024), which viewed termination as conditional on extension applications. Here, Justices Aradhe and Kumar clarified: post-expiry, the arbitrator cannot proceed without court intervention, becoming functus officio . "On expiry of initial period or extended period, the arbitrator cannot proceed... subject to an order... under Section 29A(4)."

Critically, substitution under Section 29A(6) is discretionary yet obligatory when mandates lapse, independent of Sections 14 (failure or impossibility) or 15 (termination and replacement). The Court rejected respondents' reliance on the 2022 dismissal under Sections 14/15, stating: "The Act provides separate remedies... the order dated 24.01.2022 does not have any impact." Proceedings continue seamlessly, deeming the substitute to have received prior evidence (Section 29A(6)-(7)).

The Bombay High Court extended this to statutory contexts. Under Section 19B(9) of the Highways Act, the Arbitration Act applies "subject to" its provisions. Justice Sundaresan held no override for Section 29A, as both promote expedition. Unlike Sections 11 or 15 (tied to original appointment rules, per NHAl v. Sayedabad Tea Co. , 2020), Section 29A enables court substitution without reverting to state appointment. He warned against perpetual arbitrator rotation defeating arbitration's purpose, invoking purposive interpretation to suppress such mischief.

Jurisdictionally, both courts navigated Section 2(1)(e)'s "Court" definition—principal civil court or High Court with original jurisdiction. The Supreme Court exercised appellate oversight; Bombay deferred to Navi Mumbai's district court for the seat, citing BGS SGS Soma JV v. NHPC Ltd. (2020) on juridical seat over venue.

Implications for Legal Practice

This duo of judgments bolsters arbitration's efficiency, aligning with the Act's pro-speed ethos. For practitioners:

• Timeline Compliance : Parties must vigilantly monitor deadlines. Post-expiry extensions sans substitution risk invalidation, as in Fatehpuria . No longer can arbitrators linger indefinitely.

• Substitution Powers : Courts now wield broader discretion under Section 29A(6), unmoored from eligibility challenges. This curbs dilatory tactics, favoring former judges (as appointed here) for expertise and neutrality.

• Statutory Arbitrations : The Bombay ruling expands Section 29A to acquisition disputes, preventing state foot-dragging. It signals courts' readiness to intervene in "deemed" agreements, potentially influencing sectors like highways, ports, and RFCTLARR Act arbitrations.

• COVID Adjustments : Exclusions (per In Re: Cognizance for Extension of Limitation , 2022) remain, but parties cannot rely on pandemics indefinitely.

Potential challenges include fee disputes—appellants alleged Fourth Schedule violations, though the Court focused on timelines. Future cases may litigate reductions under the proviso to Section 29A(4). Additionally, unilateral state appointments in statutory setups may face bias scrutiny post- Central Organisation for Railway Electrification v. ECI SPIC SMO MCML (JV) (2024), though not addressed here.

For the justice system, these decisions reduce backlog by mandating closure within six months post-substitution. They deter "ever-greening" via rotations, ensuring arbitration's edge over litigation. As Justice Sundaresan noted: "Timely and speedy resolution outside the Courts is precisely why the Arbitration Act... has been adopted."

Broader Impact and Future Outlook

The Fatehpuria ruling impacts thousands of pending arbitrations, urging tribunals to adhere to timelines or face ouster. It reaffirms party autonomy tempered by judicial oversight, potentially increasing substitution applications. In partnership and commercial disputes, where delays inflate costs, this promotes certainty.

The Bombay decision addresses a systemic flaw in infrastructure acquisitions, where state entities often delay to minimize payouts. By empowering district courts, it decentralizes relief, easing High Court burdens. However, it leaves open whether Section 11 applies for initial appointments in such regimes—citing Sayedabad , it does not—potentially spurring legislative tweaks.

Quotes from the judgments underscore urgency. The Supreme Court: "Section 29A aims to ensure time-bound disposal... in consonance with the object of the Act." Bombay HC: "The legislative policy choice of arbitration... stands evidently frustrated on the ground."

In sum, these pronouncements fortify arbitration as a robust, efficient forum. Legal professionals must advise clients on proactive extensions and challenge lapsed mandates swiftly. As India positions itself as an arbitration hub, such judicial interventions ensure the mechanism lives up to its promise of "justice at the speed of business."
