Courts will not ordinarily interfere with the invocation of a bank guarantee — the instrument’s commercial value rests on its unconditional nature, and injunctions are available only in the narrowest circumstances of fraud, irretrievable harm, or special equities.
A bank guarantee is a legal commitment provided by a bank to pay a specified amount to a beneficiary if the bank’s customer (the debtor) fails to meet their obligations. It is a type of contract of guarantee under Section 126 of the Indian Contract Act, 1872, where a third party (the bank) promises to discharge the liability of another if that party defaults. In State Trading Corp. of India Ltd. v. Jainsons Clothing Corp., the Supreme Court recognised a bank guarantee as a trilateral agreement between the bank, debtor, and beneficiary, where the bank commits unconditionally to honour the guarantee. Conditional guarantees can only be invoked when certain conditions are met (e.g., proof of default); unconditional guarantees must be paid on demand without the bank examining the underlying dispute.
The Supreme Court has consistently held that courts should generally avoid granting injunctions that prevent fulfilment of obligations under bank guarantees. Banks’ commitments must be honoured without judicial interference: if injunctions were easily granted, it would undermine the entire banking system. However, three narrow exceptions exist where a court may restrain invocation.
First, Fraud: if there is clear and serious fraud proven with strong evidence, going to the root of the deal (not merely alleged), courts may intervene. In U.P. Cooperative Federation Ltd. v. Singh Consultants and Engineers, the Court emphasised that there must be clear evidence both of the fraud and of the bank’s knowledge of it. Second, Irretrievable Harm or Injustice: where encashment of an unconditional guarantee would cause irretrievable harm so exceptional and irreversible that it justifies overriding the guarantee’s terms. In Svenska Handelsbanken v. M/s Indian Charge Chrome & Others, the Supreme Court upheld the exception where absence of relief would cause genuine, immediate, and non-speculative irreparable harm. Third, Special Equities: a broader but controversial and rarely invoked exception for unique circumstances; courts have cautioned that it should not be stretched too far, or the purpose of having a bank guarantee would be defeated.
The jurisprudence discussed primarily addresses unconditional guarantees. Courts have consistently held that invocation of a conditional guarantee can be restrained if the specific conditions mentioned in the guarantee are not met by the beneficiary. Banks are not meant to adjudicate disputes; their role is limited to assessing prima facie compliance with stated conditions. Parties should consider including objective and verifiable conditions — such as certification by an independent expert or prior negotiation requirements — to reduce risk of arbitrary invocation and promote commercial fairness.
