A Surety Is Not Automatically Liable for Unauthorized Overdrawings Beyond the Guaranteed Limit

The Background

A cooperative bank had sanctioned a cash-credit facility of Rs.4 lakh to the borrower, backed by contracts of guarantee executed by the sureties. The bank later alleged that, in connivance with its own officers, the borrower withdrew amounts far beyond the sanctioned limit and eventually defaulted.

The dispute travelled through the cooperative adjudicatory hierarchy, where the main controversy became whether the sureties could be made liable at all once the bank had permitted such excess withdrawals.

What the Court Considered

The Supreme Court examined the distinction between total discharge of a surety and discharge limited to transactions subsequent to a variation in the underlying contract. It treated the issue through the framework of Sections 133 and 139 of the Contract Act.

The Court rejected the proposition that the sureties must either be held liable for everything or for nothing. Instead, it emphasized that an unauthorized variance without the surety’s consent may discharge the surety only in respect of the later, altered transactions.

The Final Decision

The Supreme Court disapproved the High Court’s all-or-nothing approach and accepted the bank’s limited claim that the sureties could still be made answerable up to the originally sanctioned extent, while not being saddled with liability arising from the later overdrawings.

Why This Judgment Matters

This judgment is important because it clarifies that guarantee law does not always operate in absolutes. A creditor’s unilateral conduct may reduce or reshape the surety’s obligation without wiping out the original guarantee altogether.

It also sends a practical message to lenders: if they materially vary the risk without the surety’s consent, they cannot expect the guarantee to travel with that altered bargain automatically.
