10 Case Studies · IRAC Format
01
Operation of Partnership Accounts — Unauthorized Signatory
A banker is bound to follow the customer's mandate strictly and cannot act beyond the authority conferred.
Scenario: Raju, Ramu, Ravi and Roja are partners in a firm. They explicitly instruct the banker that only Raju and Ramu will operate the firm's current account. Later, a cheque signed by Raju and Roja is presented. Can the banker honour this cheque?
Whether a banker can honour a cheque signed by a partner who is not authorized under specific instructions given to the bank, despite the partner's implied authority.
Section 18 & 19, Indian Partnership Act, 1932 (Implied Authority of Partners), the Banker-Customer Contractual Agreement, and London Joint Stock Bank v. Macmillan & Arthur (1918).
Under Section 19 of the Indian Partnership Act, 1932, partners generally have the implied authority to bind the firm for transactions in the usual course of business. However, this implied authority can be restricted by an express agreement between partners. When such a restriction (a mandate) is communicated to the banker, it overrides the implied authority. As established in London Joint Stock Bank v. Macmillan & Arthur (1918), the banker must strictly follow the customer's mandate. Payment contrary to a mandate amounts to a breach of contract, and the banker cannot debit the customer's account for such payments.
No.Cannot Honour The banker cannot legally honour the cheque because doing so would violate the customer's mandate. Paying the cheque signed by Raju and Roja is a breach of contract, and the bank cannot debit the firm's account.
02
Payments to Minor Payees
A minor is competent to be a payee or endorsee and can receive payment, giving a valid discharge to the paying banker.
Scenario: Mr. Basappa issues a cheque for Rs. 25,000 from his Kaveri Bank current account in favour of his minor son, Ningappa. Ningappa presents the cheque for payment over the counter. Can the banker pay the amount to the minor son?
Whether a banker can make valid payment of a cheque directly to a minor payee over the counter.
Section 26, Section 10, and Section 82 of the Negotiable Instruments Act, 1881.
Section 26 NI Act states that a minor may draw, endorse, deliver, and negotiate a negotiable instrument so as to bind all parties except himself. Therefore, a minor has the statutory capacity to receive the benefit of the instrument. Under Section 10, "payment in due course" means payment in accordance with the apparent tenor of the instrument, in good faith, and without negligence. If the banker pays the minor payee in good faith, it constitutes a payment in due course, which legally discharges the bank's liability under Section 82.
Yes.Valid Payment The payment to the minor payee is valid. The banker can lawfully pay the amount to Ningappa over the counter, and the payment constitutes a valid discharge of the bank's liability.
03
Validity of Promissory Notes — Marriage Condition
A promissory note must contain an unconditional undertaking to pay; a promise contingent on an uncertain event is invalid.
Scenario: A debtor signs an instrument: "I promise to pay B or order Rs. 50,000 on the marriage day of B." Is it a valid promissory note?
Whether a promise to pay a sum of money upon the marriage of a person constitutes a valid, unconditional promissory note.
Section 4 of the Negotiable Instruments Act, 1881.
According to Section 4 NI Act, a promissory note must contain an unconditional undertaking to pay. The undertaking must not depend on a contingency. Marriage is not a certain event — it may never happen. Therefore, the promise remains conditional. Precedents establish that a promise dependent on a contingency, such as a marriage that may or may not happen, is conditional and therefore invalidates the instrument as a promissory note.
No.Not Valid The instrument is not a valid promissory note because the promise to pay is dependent on a contingency (marriage), which violates the mandatory requirement under Section 4 that a promissory note must contain an unconditional undertaking.
04
Banker's Right of Set-Off vs Joint Accounts
Set-off requires complete mutuality — same name, same capacity, same right.
Scenario: Mr. 'M' maintains a bank account in his sole name and enjoys an overdraft facility which he fails to repay despite demands. The banker adjusts the overdraft amount from the credit balance of a joint savings account held in the names of 'M' and 'N'. 'N' challenges this action. Decide.
Whether a banker has the right to set-off an individual debt of a customer against a credit balance in a joint account held by that customer with another person.
The Principle of Mutuality of Debts (Banker's Right of Set-off) and Messrs Qasim & Co. v. Bolan Bank Limited.
The banker's right of set-off (combination of accounts) allows a bank to combine accounts of the same customer to satisfy a debt. However, this right is strictly subject to the rule of mutuality: the accounts must be in the same name, same capacity, and same right. As established in Messrs Qasim & Co. v. Bolan Bank Limited, joint and several accounts operated by two or more persons cannot be adjusted against the individual deposits or debts of just one of them. There must be a strict mutuality of claim between the bank and the depositor. An individual debt of 'M' cannot be adjusted against the joint account of 'M' and 'N' as there is no mutuality.
No.Set-Off Invalid The banker cannot legally combine the accounts or set off M's individual debt against the joint account because the accounts are not held in the same right and capacity. The bank must restore the wrongfully adjusted funds to the joint account.
05
Safe Custody — Bailment vs Debtor-Creditor
Valuables deposited for safe custody create a bailment — bank must return the identical items, not equivalent value.
Scenario: A customer gives the banker a sealed cover containing 200 Re. 1 coins for safe custody. Later, when the customer demands return, the banker returns a cover containing two Rs. 100 currency notes. Is the banker's action justifiable?
Whether the deposit of a sealed cover for safe custody creates a debtor-creditor relationship or a bailment, and whether the bank can return equivalent value instead of the specific deposit.
Section 148 of the Indian Contract Act, 1872 (Bailment) and the landmark precedents: Foley v. Hill (1848), UCO Bank v. Hem C. Sarkar, and Punjab National Bank v. K.B. Shetty.
In Foley v. Hill (1848), standard money deposited in a bank ceases to be the customer's property and creates a debtor-creditor relationship. However, when a customer deposits valuables (such as a sealed cover) specifically for safe custody, the relationship changes. As held in UCO Bank v. Hem C. Sarkar and Punjab National Bank v. K.B. Shetty, safe custody deposits create a relationship of Bailor and Bailee under Section 148 ICA. In a bailment, the bank has only possession and not ownership. The bank is bound to return the identical goods and has no right to open the cover or substitute its contents.
No.Not Justifiable The banker's action is not justifiable because the transaction was a bailment, which requires the return of the identical sealed cover containing the 200 Re. 1 coins. Substituting the coins constitutes a breach of the bailee's duty and conversion of goods.
06
Cheque Presentation on a Public Holiday
If the final day of a cheque's validity falls on a holiday, the period extends to the next working day.
Scenario: Mr. Ganesh received a cheque from his friend. Due to a busy schedule, he could not present it. The 3-month validity period of the cheque is about to expire on a day which happens to be a holiday. Advise Mr. Ganesh.
Whether a cheque whose validity period expires on a public holiday can be validly presented for payment on the next working day.
Section 10 of the General Clauses Act, 1897, Section 4 of the Limitation Act, 1963, and N. M. Minerals India Private Ltd. v. P. K. Raju (2024).
Under general legal principles, if the last day of a period falls on a Sunday or public holiday, the deadline naturally extends to the subsequent open working day. In N. M. Minerals India Private Ltd. v. P. K. Raju (2024), the court affirmed that when the final day for cheque presentation falls on a holiday, the deadline naturally extends to the subsequent open working day. The cheque remains valid, and such presentation is valid for proceedings under Section 138 NI Act.
Present on next working day.Valid Presentation Mr. Ganesh should present the cheque on the immediate next working day when the bank opens. The presentation is legally valid because the law extends the validity period to the next working day when the last day falls on a holiday.
07
Cheque Dishonour — Signature Mismatch & S.138
Signature mismatch falls within the scope of Section 138 NI Act.
Scenario: A has issued a cheque for Rs. 5,000 to B for the purchase of goods. The cheque is dishonoured by the bank with the reason "drawer's signature differs/mismatch". Can B file a criminal complaint against A under Section 138 of the NI Act?
Whether dishonour of a cheque due to a signature difference/mismatch attracts criminal liability under Section 138 NI Act.
Section 138 of the Negotiable Instruments Act, 1881 and Laxmi Dyechem v. State of Gujarat (2012).
Section 138 imposes criminal liability for cheque bounce. In the landmark case of Laxmi Dyechem v. State of Gujarat (2012), the Supreme Court clarified that dishonour due to the drawer's signature mismatch falls within the ambit of Section 138. The Court noted that a signature difference is often a unilateral act of the drawer to avoid payment, and letting drawers escape liability under this pretext would defeat the purpose of the Act. A signature mismatch is treated similarly to "insufficient funds" for the purpose of Section 138.
Yes.Can File S.138 B can file a cheque bounce case against A under Section 138 because a signature mismatch is legally equated to insufficiency of funds under the Laxmi Dyechem precedent. B must first serve the 30-day statutory demand notice.
08
Minor's Fixed Deposit as Security for Parent's Loan
A guardian cannot pledge a minor's property for personal benefit — it violates the duty to act for the minor's evident benefit.
Scenario: Mr. Ishwar approaches the banker for a personal loan facility against a Fixed Deposit (FD) receipt issued in the sole name of his minor son, Ganesh. Can the banker grant the loan against this security?
Whether a natural guardian can pledge a minor's fixed deposit receipt as security for a personal loan, and whether the banker can accept such security.
Section 8 of the Hindu Minority and Guardianship Act, 1956.
Under Section 8 HMGA, a natural guardian only has the power to do acts that are necessary, reasonable, and for the evident benefit of the minor's estate. The guardian cannot mortgage, pledge, or otherwise encumber the minor's property unless permitted by law or by court order. Pledging a minor's FD for a parent's personal loan does not meet this threshold, as it exposes the minor's property to risk for the father's personal benefit. If the banker accepts the minor's FD as security, it constitutes negligence and a breach of trust, making the bank liable to the minor upon attaining majority.
No.Cannot Grant The banker cannot legally grant the loan against the minor's FD receipt because the guardian is prohibited from pledging the minor's property for personal debt, and doing so violates Section 8.
09
Firm Cheque Credited to Partner's Personal Account
Crediting a firm cheque into a partner's personal account constitutes negligence — banker loses S.131 protection.
Scenario: A cheque drawn in favour of XYZ & Co. (a partnership firm) is sent to the bank by partner Y, with a request to credit the amount directly to Y's personal savings account. Can the banker credit the cheque as requested?
Whether a collecting banker can credit a cheque drawn in favour of a partnership firm to the personal account of one of its partners without being liable for conversion.
Section 131 NI Act (Protection to Collecting Banker) and A.L. Underwood Ltd. v. Bank of Liverpool & Martins (1924).
Under Section 131 NI Act, a collecting banker receives protection against conversion if they collect in good faith and without negligence. In A.L. Underwood Ltd. v. Bank of Liverpool & Martins (1924), it was held that a bank acts negligently if it allows a partner or director to endorse cheques payable to the firm directly into their own personal account without inquiry. Such conduct amounts to negligence and deprives the banker of statutory protection under Section 131, making the bank liable to the firm for conversion.
No.Cannot Credit The banker must not credit the cheque to Y's personal account because doing so constitutes negligence, which deprives the banker of statutory protection under Section 131, rendering the bank liable for conversion.
10
I.O.U. as a Promissory Note
A mere acknowledgment of debt (I.O.U.) is not an express undertaking to pay — it is not a valid promissory note.
Scenario: R has executed an instrument in favour of X as follows: "Mr. X, I.O.U. Rs. 5,000". Is this a valid Promissory Note?
Whether a simple acknowledgement of debt (an I.O.U. — "I Owe You") constitutes a valid promissory note.
Section 4 of the Negotiable Instruments Act, 1881 and the Privy Council precedent Mohammad Akbar Khan v. Attar Singh (1936).
According to Section 4 NI Act, a promissory note must contain an unconditional undertaking to pay. In the landmark Privy Council decision of Mohammad Akbar Khan v. Attar Singh (1936), it was ruled that a document must contain an express and unconditional undertaking to pay; a mere receipt or implied promise (like an I.O.U.) is insufficient. The classic rule is that "an acknowledgment of debt is not an undertaking to pay". Since an I.O.U. is merely an acknowledgement of debt, it lacks the required express promise to pay.
No.Not Valid The instrument is not a valid promissory note because a mere acknowledgment of debt (I.O.U.) does not contain an express and unconditional undertaking to pay, as established in the Attar Singh precedent.
