Court affirms limited interference under Sections 34 and 37 of Arbitration and Conciliation Act, rejects challenge to arbitral tribunal's contract interpretation and evidentiary findings in Mumbai International Airport Limited v. Airports Authority of India
In a significant pronouncement on arbitration law, the Delhi High Court (Division Bench) on 16th October 2026 dismissed the appeal filed by Mumbai International Airport Limited (MIAL) challenging an arbitral award in its dispute with Airports Authority of India (AAI). The judgment clarifies the limited scope of judicial interference under Sections 34 and 37 of the Arbitration and Conciliation Act, 1996, particularly emphasizing that courts cannot sit in appeal over arbitral awards or substitute their interpretation merely because another view is possible.
The dispute arose from MIAL's claim that AAI was contractually obligated to transfer or assign its lessor's interest under a lease executed with Sahara Hospitality Private Limited, concerning land at the Chhatrapati Shivaji Maharaj International Airport in Mumbai. Despite several communications, interim payments by AAI to MIAL, and government policy inputs regarding airport privatization, the three-member arbitral tribunal unanimously rejected MIAL's claims. MIAL's subsequent petition under Section 34 challenging the arbitral award was dismissed by a Single Judge of the Delhi High Court.
On appeal under Section 37, the Division Bench, comprising Justices Anil Kshetarpal and Bharat Parashar, scrutinized the grounds raised by MIAL, including allegations that the Single Judge's judgment was non-speaking because it reproduced portions of the arbitral award, and objections to the tribunal's contractual interpretation and handling of evidence.
The Court reaffirmed the settled legal principle that jurisdiction under Section 34 is limited to grounds explicitly recognized by the statute, such as patent illegality or procedural irregularities, and does not permit courts to reappraise evidence or re-interpret contracts as if they were appellate courts. The appellate jurisdiction under Section 37 is even narrower, confined to ensuring the Section 34 court acted within its legal bounds.
Addressing the claim that the judgment under Section 34 was non-speaking due to reproduction of arbitral award passages, the Court clarified that adoption or reproduction of arbitral tribunal reasoning does not, per se, indicate non-application of mind. The validity of the judgment must be assessed on substance, not form. The Court distinguished between legitimate adoption of reasoning and mechanical reproduction without judicial engagement. The impugned judgment showed meaningful adjudication and application of the correct statutory standard, making the non-speaking objection unsustainable.
Regarding contractual interpretation, the Court analyzed relevant provisions of the Operation, Management and Development Agreement (OMDA) and the lease deed. While certain clauses excluded existing leases from the demised premises, another provision contemplated transfer or novation of existing contracts during the transition phase. The tribunal's interpretation, which harmonized these provisions to hold that the lessor's interest under existing leases was not automatically transferred, was found to be a plausible and reasonable construction. The Court held that mere possibility of an alternative interpretation does not justify interference.
On evidentiary matters, the Court considered MIAL's reliance on a letter dated 9th June 2006, subsequent rent payments by AAI to MIAL, and communications from the Ministry of Civil Aviation. It was held that post-contractual communications and conduct may inform contract construction but cannot amend contract terms. The tribunal's treatment of these evidentiary aspects did not disclose patent illegality or failure of jurisdiction. The Ministry's communications were correctly treated as non-binding views rather than statutory policy directions under the Airports Authority of India Act, 1994.
Summarizing, the Court found no jurisdictional error or perversity in the arbitral tribunal's reasoning or the Single Judge's judgment upholding the award. The appeal was dismissed, reinforcing the principle that courts must exercise restraint in interfering with arbitral awards and uphold arbitration's finality and efficacy.
This judgment will be a key reference for arbitration practitioners and parties engaged in complex contract disputes, especially involving public-private partnerships and government contracts, underlining the judicial deference accorded to arbitral tribunals' findings within the statutory framework.
Bottom Line:
Arbitration and Conciliation Act, 1996 - Scope of interference under Sections 34 and 37 - Mere reproduction of portions of arbitral award in judgment under Section 34 does not by itself render judgment non-speaking - Court can adopt reasoning of arbitral tribunal if it shows meaningful adjudication - Contractual interpretation by arbitral tribunal cannot be interfered with merely because another view is possible.
