The Calcutta High Court has clarified that a contractual lock-in period does not automatically override an exit clause requiring notice, and that arbitral awards must strictly adhere to the express terms of the agreement. In a significant ruling under Section 34 of the Arbitration and Conciliation Act, 1996, the Court set aside an arbitral award granting ten years of future commitment charges, holding that such relief was inconsistent with the parties’ agreed exit mechanism.
Background & Facts
The Dispute
The dispute arose from a contract dated 27.01.2016 between Mintech Global Pvt. Ltd. (claimant) and Ultra Tech Cement Limited (respondent) for the establishment of captive manufacturing units to produce fly ash bricks, AAC blocks, and ready mix mortar exclusively for the respondent’s internal consumption. The total project cost was ₹65.74 crores, of which the respondent paid ₹31.98 crores as a mobilisation advance - 50% of the total investment - repayable in 96 equated monthly instalments at 14.5% interest on reducing balance. The contract included a lock-in period of ten years, extendable by six years, and required the respondent to utilise 100% of the plant capacity.
Key Facts
- The manufacturing units became operational on: August 29, 2016 (fly ash bricks), November 2, 2016 (AAC blocks), and March 29, 2017 (ready mix mortar).
- On March 7, 2017 and March 8, 2017, the respondent sent emails directing the claimant to cease procurement of raw materials until further instructions.
- No formal termination notice under Clause 1.11 was issued.
- The respondent continued paying commitment charges until June 2017.
- The claimant filed an application under Section 17 of the Arbitration and Conciliation Act, 1996, resulting in an order dated April 16, 2018, relieving it of further obligations under the contract.
- The claimant never resumed production after March 2017.
- The claimant claimed future commitment charges for ten years from the commencement of production, amounting to ₹127.12 crores.
- The contract’s Clause 1.11 permitted exit upon six months’ written notice and full indemnification under Annexure III.
- Annexure III provided two exit scenarios: one where the claimant retained the plant, and another where the respondent did.

The Parties' Positions
Claimant (Mintech): Argued that the contract was not validly terminated; the emails did not constitute notice under Clause 1.11; the lock-in period bound the respondent to pay commitment charges for ten years regardless of usage; the Arbitral Tribunal’s interpretation was plausible and entitled to deference.
Respondent (Ultra Tech): Contended that the conduct of the parties, including cessation of production and non-resumption, amounted to mutual termination; the Arbitral Tribunal ignored Annexure III and the exit mechanism; future commitment charges were speculative and unproven; the interest reduction was contrary to the express contract.
Relief Sought
The claimant sought restoration of the Arbitral Tribunal’s award of ₹127.12 crores in future commitment charges and the 9% interest rate on mobilisation advance. The respondent sought confirmation of the Single Judge’s order setting aside the commitment charges and restoring the 14.5% interest rate.
The Legal Issue
Can a party claim future commitment charges for the full lock-in period under a contract when the other party has effectively terminated the agreement without formal notice, and the contract contains a specific exit mechanism requiring notice and indemnification?
Arguments Presented
For the Appellant/Petitioner
The claimant relied on OPG Power Generation Pvt. Ltd. v. Enexio Power Cooling Solutions and Reliance Infrastructure Ltd. v. State of Goa to argue that courts must not reappreciate evidence or substitute their view for that of the arbitrator. It contended that the Arbitral Tribunal’s finding that no valid termination occurred was plausible, given the absence of a six-month notice under Clause 1.11. It further argued that the lock-in period under Clause 1.10(A) was a binding obligation, and the exit clause could not override it without strict compliance. The claimant cited Ssangyong Engineering v. NHAI and Associate Builders v. DDA to assert that the Single Judge erred in introducing the doctrine of mitigation without pleadings or evidence.
For the Respondent/State
The respondent relied on Indian Oil Corp. v. Amritsar Gas Service to argue that where parties act as if a contract is terminated, courts may infer mutual termination even without formal notice. It contended that the Arbitral Tribunal’s award of ten years of commitment charges ignored Annexure III and the contractual exit mechanism. It further argued that the reduction of interest from 14.5% to 9% was a manifest error under Section 34(2)(a) and violated Section 31(7)(a) of the Act. It cited Gayatri Balasamy v. ISG Novasoft to support the Court’s power to correct such errors.
The Court's Analysis
The Court began by affirming the narrow scope of judicial review under Sections 34 and 37 of the Arbitration and Conciliation Act, 1996. It reiterated that courts cannot act as appellate forums and must not substitute their interpretation for that of the arbitrator unless the award is perverse, irrational, or violates fundamental policy of Indian law.
"An arbitral award can be set aside only if the arbitrator’s interpretation is not even a possible view, or if vital evidence is ignored, or if the award is contrary to the express terms of the contract."
The Court examined Clause 1.10(A) (lock-in) and Clause 1.11 (exit) together. It held that the contract explicitly contemplated exit through Annexure III, which required six months’ notice and indemnification. The fact that the respondent ceased directing production and the claimant did not resume operations after March 2017, coupled with the interim order under Section 17 relieving the claimant of obligations, established a mutual understanding that the contract was terminated.
The Court found the Arbitral Tribunal’s award of commitment charges for ten years from the date of plant commencement to be legally unsustainable. The contract’s lock-in period ran from the date of execution (27.01.2016), not from the date of production. More critically, the Tribunal ignored Annexure III, which governed the consequences of exit. The Court held that the Arbitral Tribunal had effectively rewritten the contract by ignoring the exit mechanism.
Regarding interest, the Court noted that the contract expressly prescribed 14.5% on reducing balance. The Arbitral Tribunal’s reduction to 9% was not supported by any contractual provision or legal principle. The Court cited Union of India v. Bright Power Projects to hold that an arbitrator cannot unilaterally alter a fixed contractual interest rate absent mutual agreement or statutory mandate.
The Court also rejected the claimant’s argument that mitigation was not pleaded. It held that the issue of termination and its consequences was central to the dispute, and the Single Judge’s reliance on the parties’ conduct was not a new plea but a logical inference from admitted facts.
The Verdict
The Calcutta High Court dismissed both appeals. The Arbitral Tribunal’s award of ₹127.12 crores in future commitment charges was set aside. The interest rate on the mobilisation advance of ₹31.98 crores was restored to 14.5% per annum on reducing balance from March 2017 until repayment. The Court held that commitment charges were limited to six months from March 2017, in accordance with the exit mechanism under Annexure III, as interpreted in Amritsar Gas Service. No costs were awarded.
What This Means For Similar Cases
Contractual Exit Clauses Trump Lock-in Periods Without Notice
- Practitioners must now argue that a lock-in period does not prevent termination if a valid exit mechanism exists and is triggered by conduct.
- Even in the absence of formal notice, consistent conduct indicating mutual termination may be sufficient to invoke exit provisions.
- Arbitrators cannot ignore express contractual exit conditions to award indefinite future liabilities.
Interest Rates Must Follow Contractual Terms
- Arbitrators lack authority to reduce contractually stipulated interest rates unless the contract permits discretion or the rate is unconscionable.
- Reductions based on equity or fairness are impermissible if the contract contains a clear, unambiguous rate.
- Courts may correct such errors under Section 34(2)(a) as manifest errors on the face of the award.
Mitigation Is Inherent in Termination Disputes
- The doctrine of mitigation does not require separate pleading if the issue of termination is central to the dispute.
- Conduct of parties post-alleged breach is admissible to infer mutual termination.
- Arbitrators must consider the practical reality of the parties’ actions, not just the formality of notice.
