Lead disposal beyond contractually agreed limits entitles contractor to extra payment under Quantum Meruit principles.

The Union of India (Appellant) challenged a judgment dated 09.07.2025 by the Commercial Court, Gangtok, which refused to set aside an arbitral award in favor of the Respondent contractor

The dispute arose from a contract for road works where the Respondent claimed additional payment for the disposal of surplus material (muck) beyond a 1,000-meter lead

The Sole Arbitrator, Justice Pranab Kumar Chattopadhyay, awarded the Respondent ₹7,48,74,932.80 with 9% interest, finding that the Appellant failed to provide dumping yards within the contractually agreed 1,000-meter limit

The Appellant contended that a specific document (Annexure A3) barred extra payment and that the award lacked cogent evidence

The court primarily applied Section 34 of the Arbitration and Conciliation Act, 1996, which governs the limited grounds for setting aside an arbitral award

Section 37 regarding the limited scope of appellate interference

The principle of Quantum Meruit, which allows for reasonable compensation for services rendered outside specific contractual terms unless expressly excluded

The evidentiary rule that the scope of inquiry under Section 34 cannot be enlarged by producing new documents not placed before the Arbitrator

The Court observed that the Arbitrator’s findings were rooted in the contract and applicable specifications (MORT&H), which provide for computing claims for muck disposal beyond 1,000 meters

It rejected the Appellant's reliance on Annexure A3, noting that it was not produced during arbitration and, even if considered, it applied to material used for "filling" rather than the "transportation" for dumping currently in dispute

The Court emphasized that in a Section 37 appeal, it cannot re-appreciate evidence or act as a regular appellate court; its role is restricted to ensuring the lower court correctly applied Section 34 parameters

The Court found that the Arbitrator had properly appreciated evidence regarding the actual dumping distances (up to 23.70 KM) and the lack of fault on the contractor's part

The Court held that the Arbitral Tribunal stayed within the bounds of the contract and the Commercial Court correctly declined to intervene under Section 34

The appeal was dismissed, the lower court's order was affirmed, and trial court records were ordered to be remitted
