The Bombay High Court has affirmed that monthly ship-or-pay charges under a gas transportation agreement constitute a contractual debt, not liquidated damages requiring proof of loss. This ruling reinforces the principle that parties bound by clear contractual terms cannot evade payment by recharacterizing obligations as compensatory claims.
Background & Facts
The Dispute
The petitioner, Nagarjuna Fertilizers and Chemicals Ltd., a fertilizer manufacturer in Kakinada, Andhra Pradesh, entered into a Gas Transportation Agreement dated 27.03.2009 with the respondent, Pipeline Infrastructure Ltd., a common-carrier gas pipeline operator. The agreement governed the transportation of natural gas from Gadimoga, Andhra Pradesh, to Oduru, Andhra Pradesh, for use in the petitioner’s urea production facility. The agreement was extended periodically and remained in force until 28.02.2019.
Key Facts
- The agreement included Clause 5.2, which mandated a "Monthly Ship-or-Pay" obligation: the petitioner was required to pay for at least 90% of its contracted monthly gas capacity, regardless of actual usage.
- The "Monthly Ship-or-Pay Quantity" was defined as the sum of daily Maximum Daily Quantity (MDQ) minus specific exclusions such as Force Majeure or Planned Works.
- The "Monthly Ship-or-Pay Payment" was calculated as the deficiency multiplied by the applicable Tariff under Clause 5.2(d).
- A side letter agreement dated 09.11.2017 explicitly agreed to interest at 24% per annum on delayed payments, compounded monthly.
- From 14.07.2018 to 28.02.2019, the petitioner did not utilize its full contracted capacity, but the respondent continued to invoice for ship-or-pay charges.
- The petitioner requested a waiver of these charges via letter dated 25.08.2018; the respondent rejected the request on 19.09.2018.
- The petitioner did not challenge the rejection of the waiver request or dispute the invoices under Clause 8.4 of the agreement, which deemed undisputed invoices as conclusive.
- The respondent alleged that the petitioner’s failure to pay resulted in a contractual debt of Rs. 19,26,63,408/- for the period 14.07.2018 to 28.02.2019.
Procedural History

- 08.06.2026: Judgment pronounced dismissing the petition.
Relief Sought
The petitioner sought to set aside the arbitral award dated 02.01.2023 on grounds of patent illegality, unjust enrichment, and excessive interest. Alternatively, it sought modification of the post-award interest rate from 24% to the statutory rate under Section 31(3)(b) of the Arbitration Act.
The Legal Issue
The central question was whether monthly ship-or-pay charges under a gas transportation contract constitute a contractual debt enforceable without proof of loss, or whether they are liquidated damages requiring the claimant to establish actual financial harm.
Arguments Presented
For the Petitioner
The petitioner contended that the ship-or-pay charges were in the nature of liquidated damages under Section 74 of the Indian Contract Act, 1872, and therefore required the respondent to plead and prove actual loss of earnings. It argued that since the respondent had reallocated the petitioner’s reserved capacity to third parties and earned higher tariffs from them, recovery of ship-or-pay charges amounted to unjust enrichment. The petitioner relied on Hindustan Petroleum Corporation Ltd. v. M/s. Dhampur Sugar Mills and Kailash Nath Associates v. Delhi Development Authority to assert that where a party benefits from the reserved capacity, enforcing fixed charges without loss proof is inequitable. It further challenged the 24% post-award interest as contrary to Section 31(3)(b) of the Arbitration Act, which mandates interest at 2% above the prevailing rate unless otherwise agreed.
For the Respondent
The respondent argued that the ship-or-pay charges were not damages but a fixed contractual obligation under Clauses 5.1 and 5.2 of the agreement, enforceable as a debt. It emphasized that the contract explicitly distinguished between liquidated damages (Clause 6) and ship-or-pay charges (Clause 5), and that the petitioner had never disputed the invoices under Clause 8.4. The respondent relied on India Bulls Properties v. Treasure World Developers to establish that an ascertained contractual sum constitutes a debt. It further contended that the 24% interest rate was contractually agreed upon in the side letter dated 09.11.2017 and was therefore valid under Section 31(7) of the Arbitration Act. The respondent also invoked Ssangyong Engineering v. NHAI and Parsa Kente Collieries v. Rajasthan RVUNL to argue that courts cannot reappreciate contractual terms under Section 34.
The Court's Analysis
The Court undertook a meticulous review of the contract’s structure, focusing on the distinction between Clause 5 (ship-or-pay charges) and Clause 6 (liquidated damages). It noted that Clause 5.2(d) defined the Monthly Ship-or-Pay Payment as a direct multiplication of deficiency by tariff, with no reference to loss, damage, or estimation of harm. In contrast, Clause 6.2 explicitly addressed liquidated damages for breach of other obligations. This textual distinction was decisive.
"The claim is not for damages arising from breach, but for enforcement of a pre-agreed payment mechanism tied to capacity reservation. The contract does not treat this as compensation for loss; it treats it as a price for the reserved right to transport gas."
The Court rejected the petitioner’s reliance on Hindustan Petroleum and Kailash Nath, distinguishing those cases where the contractual clause explicitly described the payment as a "true estimate of loss." Here, the language was purely operational and commercial, consistent with industry norms under the Petroleum and Natural Gas Regulatory Board Act, 2006.
Regarding unjust enrichment, the Court held that the respondent’s use of reserved capacity to serve other shippers under the Access Code was not a breach but a permitted practice under Clause 10 of the Operating Code. The petitioner had no contractual right to prevent such reallocation, and the respondent’s earnings from third parties did not negate its right to enforce the agreed ship-or-pay mechanism.
On interest, the Court found no illegality. The side letter dated 09.11.2017 clearly stipulated 24% interest on delayed payments, and the arbitrator applied this rate only to the principal claim amount from the date of filing, not compounding it as in the side letter. The Court emphasized that Section 31(7) permits parties to agree on interest rates, and the arbitrator’s application of 24% as simple interest from the claim filing date was within contractual bounds. The Court further held that Gayatri Balasamy did not empower it to substitute a reasonable rate where the parties had expressly agreed to a higher rate.
The Court reiterated the narrow scope of Section 34 review: courts cannot reappreciate evidence or substitute their interpretation for a plausible one. The arbitrator’s reading of the contract was not only possible but also commercially rational and consistent with regulatory frameworks.
The Verdict
The petition was dismissed. The arbitral award dated 02.01.2023 stands confirmed. The petitioner is directed to pay Rs. 19,26,63,408/- as the principal amount, with simple interest at 24% per annum from 19.11.2019 until the date of award, and further simple interest at 24% per annum from 02.01.2023 until full realization. The Court upheld the arbitrator’s interpretation of the contract and rejected all grounds of challenge under Section 34 of the Arbitration Act.
What This Means For Similar Cases
Contractual Debt Trumps Claims of Unjust Enrichment
- Practitioners must distinguish between contractual payment obligations and liquidated damages clauses. Where a clause fixes a payment based on capacity reservation, not breach, it is a debt.
- Evidence of third-party usage or higher earnings by the service provider does not invalidate a ship-or-pay obligation unless the contract explicitly prohibits such reallocation.
Interest Rates Agreed in Side Letters Are Binding
- Parties may contractually agree to interest rates exceeding statutory limits under Section 31(7). Courts will not interfere unless the rate is unconscionable or the agreement is void.
- Post-award interest at agreed rates is enforceable even if higher than Section 31(3)(b)’s default rate.
Section 34 Review Is Extremely Limited
- Arbitrators’ interpretations of commercial contracts are final unless perverse or contrary to law.
- Courts must not reweigh evidence or substitute their view for a plausible one, even if another interpretation seems more equitable.
- Challenges under Section 34 cannot be used as a disguised appeal on merits.
Key Takeaway for Practitioners
- Drafting clarity is critical: Use separate clauses for "payment obligations" and "liquidated damages."
- Always document side agreements on interest and penalties in writing.
- In arbitration, focus on contractual language, not equitable arguments, when defending fixed charges.
