Surety Discharged Only for Excess Overdrawal Under Section 133 Contract Act: Supreme Court Clarifies Limited Liability

Case Name: Bhagyalaxmi Co-Operative Bank Ltd. v. Babaldas Amtharam Patel (D) through Legal Representatives & Others

Citation: 2026 INSC 205; Civil Appeal No. 3200 of 2016

Date of Judgment/Order: 27 February 2026

Bench: Hon’ble Mrs. Justice B.V. Nagarathna and Hon’ble Mr. Justice Ujjal Bhuyan

Held: The Supreme Court held that under Section 133 of the Indian Contract Act, 1872, a surety is discharged only in respect of transactions subsequent to a variance made without the surety’s consent and not from the entire liability. Where a bank permits the principal debtor to withdraw amounts in excess of the originally sanctioned loan without informing the sureties, such variance discharges the sureties only to the extent of the excess overdrawn amount. Section 139 of the Contract Act would not apply in absence of impairment of the surety’s eventual remedy against the principal debtor.

Summary: The appellant-bank sanctioned a cash-credit facility of Rs. 4,00,000 to the principal borrower, for which respondent Nos. 1 and 2 stood as sureties. The borrower subsequently withdrew amounts far exceeding the sanctioned limit. Upon default, the bank initiated recovery proceedings. The Board of Nominees decreed recovery only against the principal borrower and dismissed the claim against the sureties. The Co-Operative Tribunal reversed this and held the sureties liable to the extent of Rs. 4,00,000 with interest. The High Court, however, allowed the sureties’ writ petition, holding that under Sections 133 and 139 of the Contract Act, the sureties must either be liable for the entire loan or not at all, and that permitting overdrawal discharged them completely. Before the Supreme Court, the bank argued that Section 133 discharges a surety only for transactions subsequent to the variance, whereas the sureties relied on Section 139, contending that their rights were impaired. The Court examined Sections 133 and 139, relevant precedents including Basavaraj, M/s Indexport Registered, and Radha Kanta Pal, and clarified that Section 133 applies where there is variance in contractual terms without the surety’s consent, leading to discharge only for subsequent transactions. Section 139 requires impairment of the surety’s eventual remedy against the principal debtor, which was not established in the present case.

Decision: The appeal was allowed, the High Court’s judgment dated 25.06.2008 was set aside, and it was held that the sureties are liable to the extent of Rs. 4,00,000 with applicable interest as originally sanctioned, but not for excess amounts withdrawn beyond the sanctioned limit. Parties were directed to bear their respective costs.
