Case Note & Summary
The Supreme Court considered a civil appeal arising out of a special leave petition against an order of the High Court of Delhi passed under Section 11 of the Arbitration and Conciliation Act, 1996 appointing a separate arbitrator for disputes under the T-Fiber Agreement. The appellant, M/s STL Networks Limited, and the respondent, Caspian India Engicon Pvt. Ltd., were parties to two distinct contracts for optical fiber cable services, namely the Mahanet Agreement and the T-Fiber Agreement. The respondent had initiated arbitration under the Mahanet Agreement before the High Court of Delhi, where Ms. Saumya Tandon was appointed as sole arbitrator on 16.09.2025. Subsequently, disputes arose under the T-Fiber Agreement as well, leading to a separate application under Section 11 before the same High Court, which appointed another arbitrator. The appellant contended that it had a material recovery claim under the T-Fiber Agreement, which was more than double the claim under the Mahanet Agreement, and that this claim was entitled to be exercised as a cross-project set-off against amounts payable under the Mahanet Agreement. The appellant sought modification of the impugned order to have the same arbitrator handle both arbitrations. The Supreme Court granted leave and observed that it would not go into the merits of the matter. However, in the fitness of things, the Court was of the opinion that the arbitration should be carried on by the very same arbitrator, namely the first appointed arbitrator. Accordingly, the Court directed that Ms. Saumya Tandon, appointed as sole arbitrator on 16.09.2025, shall be the arbitrator in the present dispute as well. The impugned order was modified to that extent. The Court clarified that it had not held on the merits of the cross-project set-off or the quantum of claims under the two separate agreements, and that the parties were entitled to raise all contentions before the arbitrator. The appeal was allowed and pending applications were rejected.

The Supreme Court did not address merits but directed that the same first-appointed arbitrator, Ms. Saumya Tandon, shall act as arbitrator in the present dispute also, modifying the impugned order to that extent.

Final Decision
