Court affirms arbitrator’s jurisdiction over disputes arising from void contracts, applying Coal Mines (Special Provisions) Act, 2015 and principles of restitution to safeguard third-party contractors
In a significant judgment dated May 6, 2026, the Calcutta High Court, presided by Justice Shampa Sarkar, dismissed the challenge filed by the West Bengal Mineral Development and Trading Corporation Limited (WBMDTC) against an arbitration award that upheld certain claims of Trans Damodar Coal Mining Pvt. Ltd., the contractor engaged by WBMDTC for mining operations in the Trans Damodar Coal Block.
The dispute arose after the Supreme Court of India’s landmark decisions in 2014 (Manohar Lal Sharma v. Principal Secretary) declared the allotment of coal blocks, including the Trans Damodar sector allotted to WBMDTC, as illegal and void ab initio under the Coal Mines (Nationalization) Act, 1973 (CMN Act). Consequently, the mining contract between WBMDTC and the contractor also became void. The coal mining rights were later reallocated under the Coal Mines (Special Provisions) Act, 2015 (the 2015 Act), enacted to implement the Supreme Court’s directions and ensure energy security for the country.
WBMDTC contended that since the contract was void ab initio, the arbitrator lacked jurisdiction and the claims made by the contractor under the contract were unenforceable. They argued that the 2015 Act was intended only to protect successful bidders and allottees, not contractors of prior allottees, and thus the arbitration award allowing certain claims was patently illegal and against public policy.
However, the Calcutta High Court upheld the award, emphasizing several critical legal principles:
1. Separability of Arbitration Clause: The court relied on Section 16(1)(b) of the Arbitration and Conciliation Act, 1996, recognizing the doctrine of separability of arbitration clauses. This means that even if the underlying contract is void, the arbitration clause survives, and the arbitrator retains jurisdiction to decide disputes arising from such void contracts.
2. Restitution and Prevention of Unjust Enrichment: The arbitrator rightly applied Section 65 of the Indian Contract Act, 1872, which mandates that any person who has received an advantage under a void contract must restore it or compensate the other party. The contractor was thus entitled to refund of amounts wrongfully retained or deducted by WBMDTC despite the contract being void.
3. Application of the Coal Mines (Special Provisions) Act, 2015: The 2015 Act contained non-obstante clauses protecting various stakeholders. Specifically, Section 11(2) protects third-party contractors by providing that if a successful bidder/allottee elects not to adopt contracts entered by prior allottees, those contracts cease to be enforceable against the successful bidder but the remedy remains against the prior allottee. Section 14 further clarifies liabilities of prior allottees for periods before vesting orders. The arbitrator’s interpretation that these provisions protect the contractor’s claims against WBMDTC was held to be a plausible and judicially sound view.
4. Limited Scope for Court Interference under Section 34 of Arbitration Act: The court reiterated that it cannot act as an appellate authority to reappraise evidence or substitute its view for that of the arbitrator. Interference is warranted only in cases of patent illegality, perversity, or violation of fundamental public policy. The arbitrator’s findings were found to be reasoned, supported by evidence and law, and not perverse or illegal.
5. Claims Allowed and Rejected: The arbitrator allowed claims relating to refund of additional levy wrongly appropriated by WBMDTC, penalties wrongfully imposed, dues on mining charges, refund of land advance, and share in escrow accounts, among others. Claims for future loss of profit and damages arising from contract termination were rightly rejected as the contract was void, and such reliefs are unavailable in cases of frustration or illegality.
6. Protection of Public Interest and Legislative Intent: The court acknowledged that the 2015 Act was enacted in public interest to ensure energy security and continuity of coal mining operations, rationalize liabilities and protect innocent third parties, rather than to nullify the Supreme Court’s cancellation of illegal allocations.
The court dismissed the WBMDTC’s challenge, affirming the arbitrator’s award dated June 13, 2019, which granted the contractor reliefs based on the principle of restitution and statutory protections under the 2015 Act. The judgment highlights the evolving jurisprudence on arbitration, the doctrine of separability, and the interplay between statutory law and contract law in mining sector disputes.
This decision also underscores the judiciary’s cautious approach in interfering with arbitral awards, respecting arbitral autonomy except in cases of clear illegality or violation of public policy.
The parties are now expected to execute the award, facilitating financial redress to the contractor despite the void status of the underlying mining contract.
Bottom line:-
Arbitration - Award passed by arbitrator based on principles of restitution and protection provided under the Coal Mines (Special Provisions) Act, 2015 - Arbitrator retains jurisdiction to decide disputes even when the contract is declared void, applying the principle of separability of the arbitration clause.
