Introduction
A bank guarantee in India is one of the most widely used instruments of commercial security, appearing in infrastructure and construction contracts, public procurement, supply arrangements and mobilisation advance structures. Its value to the beneficiary lies in the certainty of immediate payment, since the beneficiary does not have to prove a breach or quantify its loss through litigation before the bank pays.
Indian courts have built a consistent body of law around this commercial purpose, treating the unconditional bank guarantee as an autonomous undertaking and confining judicial interference with its invocation to a narrow set of exceptional cases. This article examines how that position has developed, what a party must show to restrain encashment of a bank guarantee, and how recent decisions have tested the boundaries of the rule.
Why a Bank Guarantee Stands Apart from the Underlying Contract
The Three-Party Structure
Every bank guarantee rests on three distinct relationships. The first is the commercial contract between the beneficiary and the party whose performance is being secured, the second is the arrangement under which that party procures the guarantee from its bank, and the third is the guarantee itself, which is a separate contract between the bank and the beneficiary. Indian courts have consistently treated the third relationship as independent of the first.
In State of Maharashtra v. National Construction Co., (1996) 1 SCC 735, the Supreme Court recognised that a claim to enforce a bank guarantee and a claim for damages under the principal contract may arise from separate causes of action. The independence is deliberate, because the beneficiary bargains for security that can be realised without waiting for the outcome of the main dispute.
Bank Guarantee versus a Contract of Guarantee under the Contract Act
A contract of guarantee is defined in Section 126 of the Indian Contract Act, 1872, and under Section 128 the liability of a surety is ordinarily coextensive with that of the principal debtor. An unconditional bank guarantee operates differently, because the bank’s obligation is measured by the terms of the instrument rather than by the debtor’s actual liability under the underlying contract. The bank is therefore not required to ascertain whether a breach has occurred, whether the beneficiary has suffered loss, or whether the beneficiary will ultimately succeed.
In Ansal Engg. Projects Ltd. v. Tehri Hydro Development Corpn. Ltd., (1996) 5 SCC 450, the Supreme Court held that the bank must honour an unconditional guarantee according to its terms regardless of disputes between the contracting parties. The Court added in Vinitec Electronics (P) Ltd. v. HCL Infosystems Ltd., (2008) 1 SCC 544, that a guarantee does not become conditional merely because it refers to the underlying contract, unless its operative part imports conditions into the bank’s payment obligation.
Although the guarantee is autonomous, the forum for an injunction suit is still tested against the material facts of the dispute. In South East Asia Shipping Co. Ltd. v. Nav Bharat Enterprises (P) Ltd., (1996) 3 SCC 443, the Supreme Court held that the execution of a guarantee in Delhi and its transmission to Bombay did not confer jurisdiction on the Delhi High Court where the underlying contract had been concluded and performed in Bombay.
Conditional and Unconditional Bank Guarantees: The Language Governs Liability
Any challenge to the invocation of a bank guarantee begins with the instrument itself, and courts look at its operative terms rather than the label the parties have given it. A conditional bank guarantee makes payment depend on conditions expressly set out in the document, such as certification of default, a prescribed form of demand, or invocation by a named authority, and the beneficiary must satisfy those conditions before the bank is obliged to pay.
The Supreme Court affirmed in Karnataka State Khadi & Village Industries Board v. Punjab National Bank, (2014) 1 SCC 625, that the terms of the guarantee determine whether the obligation is conditional. An unconditional bank guarantee, by contrast, usually contains an undertaking to pay on demand, without demur or notwithstanding any dispute, and the bank must pay once a demand conforming to the instrument is made.
The distinction is substantive rather than formal. In Hindustan Construction Co. Ltd. v. State of Bihar, (1999) 8 SCC 436, the guarantee was described as unconditional, but the bank’s liability was tied to specified events and a particular mode of invocation, and the Supreme Court therefore refused to treat it as an unconditional and unequivocal undertaking. In Standard Chartered Bank v. Heavy Engg. Corpn. Ltd., (2020) 13 SCC 574, the Court held that a guarantee must be read as a whole and that the bank’s liability cannot be stretched beyond what the instrument provides.
The Rule Against Injunctions on Encashment of a Bank Guarantee
The settled position is that courts should be slow to grant an injunction against the encashment of a bank guarantee, because routine interference would destroy the commercial utility of the instrument. The foundation was laid in United Commercial Bank v. Bank of India, (1981) 2 SCC 766, a letter of credit case in which the Supreme Court stressed that courts should not disturb the ordinary course of banking commitments save in exceptional circumstances.
In U.P. Coop. Federation Ltd. v. Singh Consultants and Engineers (P) Ltd., (1988) 1 SCC 174, the Court extended this reasoning to bank guarantees, holding that banks must be allowed to honour their commitments free from judicial interference, since any other approach would erode trust in domestic and international commerce, and that a dispute between the principal debtor and the beneficiary is no ground for restraining payment.
Subsequent decisions applied the rule firmly. In General Electric Technical Services Co. Inc. v. Punj Sons (P) Ltd., (1991) 4 SCC 230, the Court held that the bank has no concern with disputes over the amount due under the main contract, and in National Thermal Power Corpn. Ltd. v. Flowmore (P) Ltd., (1995) 4 SCC 515, it held that the pendency of arbitration does not by itself justify restraining encashment. Hindustan Steelworks Construction Ltd. v. Tarapore & Co., (1996) 5 SCC 34, rejected serious disputes over breach, pending arbitration and counterclaims as grounds for an injunction.
The principles were consolidated in Himadri Chemicals Industries Ltd. v. Coal Tar Refining Co., (2007) 8 SCC 110, where the Supreme Court held that the beneficiary of an unconditional bank guarantee may realise it irrespective of pending disputes and that interference is permissible only in cases of egregious fraud or irretrievable injustice. The party resisting encashment thus carries a heavy burden, and showing that the demand is harsh, disputed or possibly unjustified does not discharge it.
Fraud as an Exception to Encashment
The fraud exception is available only where the fraud is egregious, goes to the root of the transaction, is one of which the beneficiary seeks to take advantage, and is known to the bank. In the U.P. Coop. Federation case, the Supreme Court required the fraud to be of a kind that vitiates the very foundation of the guarantee or the underlying transaction, and made clear that an allegation of breach or wrongful invocation does not meet that standard. Svenska Handelsbanken v. Indian Charge Chrome, (1994) 1 SCC 502, held that averments in a plaint do not establish a strong prima facie case of fraud and that suspicion is insufficient.
The courts have also insisted on proper pleading. In Dwarikesh Sugar Industries Ltd. v. Prem Heavy Engg. Works (P) Ltd., (1997) 6 SCC 450, the Supreme Court held that bald allegations of fraud unsupported by particulars cannot sustain an injunction and criticised the grant of injunctions on grounds outside the recognised exceptions.
Reliance Salt Ltd. v. Cosmos Enterprises, (2006) 13 SCC 599, held that a mere breach of contract does not amount to fraud, and Mahatma Gandhi Sahakra Sakkare Karkhane v. National Heavy Engg. Coop. Ltd., (2007) 6 SCC 470, cautioned that invoking the word fraud or pointing to disputes cannot defeat a guarantee that is otherwise invocable on its terms. On the requirement of the bank’s knowledge, Millenium Wires (P) Ltd. v. State Trading Corpn. of India Ltd., (2015) 14 SCC 375, decided in the context of letters of credit, rejected vague and unsupported allegations of collusion against the negotiating bank.
Irretrievable Injustice and Special Equities
The second exception covers cases of irretrievable injustice, often described as special equities, and it is equally narrow. The harm must be such that the party opposing encashment would be left without an effective remedy even if it ultimately succeeds, and ordinary financial loss does not qualify.
In Svenska Handelsbanken, the Supreme Court adopted this threshold by reference to Itek Corpn. v. First National Bank of Boston, 566 F Supp 1210, where recovery had become practically impossible because of political upheaval in Iran and the freezing of Iranian assets, and Indian courts have since treated that case as illustrating the degree of hardship required. U.P. State Sugar Corpn. v. Sumac International Ltd., (1997) 1 SCC 568, held that the injustice must make it impossible for the guarantor to reimburse itself if it succeeds, and that apprehended difficulty in recovery is not enough.
The courts have refused to let special equities become a general fairness ground. Dwarikesh Sugar warned against diluting the rule of non-interference through broad equitable arguments, and in BSES Ltd. v. Fenner India Ltd., (2006) 2 SCC 728, the Supreme Court held that the beneficiary is generally the best judge of whether and why a performance bank guarantee should be invoked, so that the court should not examine whether a breach has occurred at the stage of invocation. In Himadri Chemicals, the Court rejected the argument that the absence of a foreign beneficiary’s assets in India amounted to irretrievable injustice.
Invocation Contrary to the Terms of the Guarantee
A separate ground for interference arises where the invocation does not conform to the guarantee itself. This is not an exception to a valid invocation but a direct consequence of treating the guarantee as an independent contract enforceable only according to its terms. In Larsen & Toubro Ltd. v. Maharashtra SEB, (1995) 6 SCC 68, the Supreme Court examined several guarantees furnished under one contract, declined to interfere with most of them, but restrained invocation of a guarantee linked to retention money whose purpose had already been served.
In Gangotri Enterprises Ltd. v. Union of India, (2016) 11 SCC 720, the Court restrained encashment of a guarantee furnished under one contract that was sought to be invoked for disputes arising under another, a decision that rests on its facts and confirms that a guarantee can be invoked only for the purpose and in the manner for which it was given. The same reasoning applies where a demand is made by someone other than the beneficiary or in a form the instrument does not permit, and in such cases the court confines itself to the terms of the guarantee without entering into the merits of the underlying dispute.
Bank Guarantee Disputes in Arbitration under Sections 9 and 17
Challenges to the invocation of a bank guarantee often arise as applications for interim relief under Section 9 of the Arbitration and Conciliation Act, 1996 before a court, or under Section 17 before the arbitral tribunal. The choice of forum does not change the substantive test, and the applicant must still bring its case within the recognised exceptions. Because the guarantee is independent, the pendency of arbitration is not a ground for restraint, and a party that succeeds in the arbitration retains its remedy of restitution, damages or adjustment.
The Supreme Court’s decision in N.N. Global Mercantile (P) Ltd. v. Indo Unique Flame Ltd., (2021) 4 SCC 379, is relevant on the separate question of arbitrability, and its discussion on this point should be kept distinct from its later history on stamp duty. Relying on A. Ayyasamy v. A. Paramasivam, (2016) 10 SCC 386 and Rashid Raza v. Sadaf Akhtar, (2019) 8 SCC 710, the Court held that allegations of fraudulent invocation of a bank guarantee are arbitrable where they concern civil or commercial rights between the parties and do not raise serious issues of public law or criminality.
Arbitrability and interim restraint remain different questions, so a dispute may be referable to arbitration while an injunction against encashment still depends on meeting the fraud or irretrievable injustice threshold.
Recent Judicial Trends: Covid-19, Proportionality and Regulatory Guarantees
Litigants have attempted to widen special equities through newer arguments, and the decisions show a cautious response. In Halliburton Offshore Services Inc. v. Vedanta Ltd., 2020 SCC OnLine Del 542, the Delhi High Court granted limited ad interim protection against invocation in the extraordinary setting of the sudden Covid-19 lockdown, but the decision did not create a general pandemic exception. In Zee Entertainment Enterprises Ltd. v. Railtel Corpn. of India Ltd., 2021 SCC OnLine Del 5004, the same Court indicated that financial difficulty or commercial hardship does not by itself amount to special equities.
Proportionality has also entered the discussion. In Chennai Metro Rail Ltd. v. Transtonnelstroy – Afcons (JV), 2021 SCC OnLine Mad 5637, affirmed by the Supreme Court in (2024) 6 SCC 211, the Madras High Court treated proportionality as part of the special equities analysis on highly specific facts, including the size of the guarantee, whether it should already have stood reduced, the absence of a crystallised claim, liquidity concerns and a direction to keep the guarantee alive. The decision is best understood as an exceptional case rather than an invitation to review the merits of every invocation on proportionality grounds.
For guarantees furnished in regulatory settings, the ordinary principles continue to apply. In A.P. Pollution Control Board v. CCL Products (India) Ltd., (2019) 20 SCC 669, the Supreme Court held that where a guarantee securing compliance with environmental directions is invoked in accordance with its terms, neither the bank nor the court should question the justification for invocation in the absence of fraud, irretrievable injustice or special equities.
Conclusion
The law on encashment of bank guarantees in India is anchored in commercial certainty. The beneficiary of an unconditional bank guarantee is ordinarily entitled to payment according to its terms, the bank is not expected to adjudicate the underlying dispute, and the court does not review the merits of the principal contract at the stage of invocation. Interference remains possible only where the fraud is egregious, particularised and known to the bank, where the injustice is genuinely irretrievable rather than merely financial, or where the invocation departs from the terms of the guarantee.
Decisions on Covid-19 disruption, proportionality and regulatory guarantees have tested these limits without displacing them, and a party seeking to resist encashment must therefore build its case on the language of the instrument and the recognised exceptions rather than on the strength of its position in the underlying contractual dispute.
