1. Meaning

Credit Card Disputes are legal disputes arising between a credit-card holder and a bank/card issuer, merchant, payment intermediary, or other entity concerning the issuance, use, billing, payment, unauthorized transactions, interest, fees, fraud, credit limits, recovery, or cancellation of a credit card.

Common disputes include:

• unauthorized credit-card transactions;
• stolen-card transactions;
• disputed purchases;
• fraudulent online transactions;
• incorrect billing;
• excessive interest;
• penal charges;
• annual or service fees;
• failure to reverse fraudulent transactions;
• wrongful recovery proceedings;
• credit-score/CIBIL consequences;
• unauthorized EMIs;
• merchant disputes;
• defective goods/services purchased through cards;
• cancellation and refund disputes;
• non-compliance with RBI directions.

In India, credit-card disputes can involve contract law, banking law, consumer protection law, RBI regulations, electronic-payment rules, tort principles and civil procedure.

2. Basic Legal Relationship

A credit-card transaction normally involves several parties:

Cardholder → Card Issuing Bank → Payment Network → Merchant/Acquiring Bank → Merchant

For example:

A customer purchases a ₹50,000 laptop using a credit card.

If the customer later claims:

“I never made this transaction,”

the dispute may involve:

1. whether the transaction was authorised;
2. whether authentication occurred;
3. whether the bank followed security procedures;
4. whether the customer reported the transaction promptly;
5. whether the customer disclosed OTP/card credentials;
6. who bears the loss;
7. whether RBI customer-protection rules apply.

3. Major Types of Credit Card Disputes

A. Unauthorized Transaction Disputes

These arise when transactions are made without the cardholder's authority.

Examples:

• stolen physical card;
• card details stolen online;
• phishing;
• card-not-present fraud;
• unauthorized recurring payment;
• fraudulent EMI;
• identity theft.

RBI's customer-protection framework provides for zero or limited liability depending upon the circumstances and the speed with which the customer reports the unauthorized transaction. The framework also places the burden of establishing customer liability on the bank.

4. Zero Liability

A customer can have zero liability where:

Situation 1 — Bank's negligence

The unauthorized transaction results from the bank's contributory fraud, negligence or deficiency.

Situation 2 — Third-party breach

The breach occurs elsewhere in the system and neither the bank nor customer is at fault, provided the customer reports it within the prescribed period.

RBI's framework requires banks to provide 24×7 mechanisms for reporting unauthorized transactions and loss/theft of payment instruments.

5. Customer Negligence

The position is different where the loss results from customer negligence.

Examples:

• sharing OTP;
• sharing PIN;
• disclosing CVV;
• giving card credentials to a fraudster;
• knowingly permitting another person to use the card.

Under RBI's framework, the customer bears the loss attributable to such negligence until the transaction is reported; subsequent losses after reporting are borne by the bank.

Therefore:

Prompt reporting is extremely important in credit-card disputes.

6. Burden of Proof

An important principle is:

The bank bears the burden of proving customer liability in an unauthorized electronic transaction dispute.

This has been emphasised in recent Indian decisions applying the RBI framework.

A bank therefore cannot necessarily defeat a claim merely by saying:

“The transaction was successfully authenticated.”

The bank may need to establish the relevant facts concerning authorization, customer negligence, authentication and applicable security procedures.

7. Case Law 1 — Hongkong & Shanghai Banking Corporation Ltd. v. Awaz & Ors., 2024 INSC 1044

This is presently one of the most important Supreme Court authorities on credit-card disputes involving interest and banking regulation.

The litigation arose from an NCDRC decision concerning credit-card interest rates of approximately 36%–49% per annum.

The NCDRC had treated interest above 30% as an unfair trade practice.

The Supreme Court set aside that approach. It held, among other things, that consumer fora could not simply rewrite the contractual interest terms of credit-card facilities or intrude into the regulatory domain assigned to the RBI.

Principle

Where credit-card terms and applicable regulatory requirements have been disclosed, a consumer forum cannot simply substitute its own preferred interest rate for the contractual arrangement.

Importance

This case is critical for disputes concerning:

• interest rates;
• contractual credit-card terms;
• RBI regulatory authority;
• unfair trade practice allegations;
• jurisdiction of consumer fora.

Important current position: the earlier NCDRC 30% ceiling cannot be treated as the prevailing Supreme Court rule.

8. Case Law 2 — Central Bank of India v. Ravindra, (2002) 1 SCC 367

This Supreme Court case is a foundational authority on interest, penal interest and capitalization in banking transactions.

The Court explained the legal distinction between:

• contractual interest;
• interest on principal;
• penal interest;
• capitalization;
• compound interest.

It emphasized that the contractual and statutory framework governing interest must be considered carefully.

Relevance to credit cards

Credit-card disputes frequently involve arguments concerning:

• interest on outstanding balances;
• delayed-payment charges;
• capitalization;
• penal charges;
• interest calculations.

Principle

Interest liability must be examined in accordance with the governing contract, banking law and applicable regulatory directions.

The decision is particularly useful when calculating disputed credit-card balances.

9. Case Law 3 — Canara Bank v. Canara Sales Corporation, (1987) 2 SCC 666

This Supreme Court decision concerned unauthorized banking transactions and forged instruments.

The Court placed significant responsibility on the bank where the customer disputed the authenticity of transactions and the bank failed to establish the customer's authorization.

Principle

A bank cannot automatically shift the consequences of a disputed unauthorized transaction onto the customer merely because the transaction appears in the bank's records.

Relevance

Although the case predates modern credit-card technology, its reasoning is highly relevant to:

• forged transactions;
• unauthorized debits;
• banking negligence;
• evidentiary burden;
• customer protection.

Modern RBI rules provide a more specific framework for electronic transactions.

10. Case Law 4 — SBI Cards & Payments Services Ltd. v. Vishal Sabharwal, NCDRC, 16 June 2020

The consumer had disputed eight credit-card transactions amounting to ₹39,999, stating that they were carried out without his knowledge. An FIR was also lodged, and the Banking Ombudsman had advised the card issuer to pay the disputed amount.

Principle

Credit-card issuers must properly investigate allegations of unauthorized transactions and cannot simply impose liability upon a cardholder without adequately addressing the dispute.

Importance

The case demonstrates the interaction between:

Credit-card dispute → bank investigation → Banking Ombudsman → consumer forum.

11. Case Law 5 — HDFC Bank Ltd. v. Dikshit Thukral, 2026

This recent consumer decision is particularly relevant to unauthorized credit-card transactions.

The dispute involved unauthorized credit-card transactions from an earlier period. The bank argued that the RBI 2017 framework should protect it because the transactions were from 2011.

The Commission recognised that the 2017 RBI framework could not be applied retrospectively to those transactions, but separately considered whether the bank was deficient under the applicable law.

Principle

RBI customer-protection rules cannot automatically be applied retrospectively to transactions that occurred before their commencement.

However, a bank may still face liability under other applicable principles where deficiency in service is established.

Importance

This case illustrates the need to determine:

1. when the transaction occurred;
2. which RBI circular was applicable at that time;
3. whether the customer was negligent;
4. whether the bank independently committed deficiency.

12. Case Law 6 — Tilak Shankar Mazumder v. Office of RBI Ombudsman, 2026

This recent decision concerned unauthorized use of a stolen credit card.

The bank argued that the card could be used without PIN/OTP and therefore the customer should have exercised additional caution.

The court rejected the bank's attempt to shift liability without evidence establishing customer negligence. It relied on the RBI framework under which the burden of proving customer liability lies on the bank.

Principle

A bank cannot establish customer negligence merely by making an allegation.

It must produce evidence capable of establishing that the customer's conduct caused or contributed to the unauthorized loss.

Importance

This is particularly useful in cases involving:

• stolen cards;
• card-not-present transactions;
• absence of OTP;
• unauthorized POS transactions;
• disputed authentication.

13. Case Law 7 — Hare Ram Singh v. Reserve Bank of India & Ors., 2024

The Delhi High Court considered the RBI framework for unauthorized electronic transactions.

The court reproduced and applied the principles concerning:

• zero liability;
• customer negligence;
• reporting periods;
• limited liability;
• burden of proof.

The court emphasized that where the customer is negligent, liability can attach until the unauthorized transaction is reported; where the customer is not responsible and the applicable reporting requirements are satisfied, RBI's protective framework may provide zero or limited liability.

Principle

The timing of the customer's complaint is legally significant.

14. Case Law 8 — Commissioner of GST & Central Excise v. Citibank N.A., 2024 INSC 808

The Supreme Court considered the nature and scope of credit-card services in the context of taxation.

The case examined the credit-card business model and the distinction between credit-card services and other banking/payment activities.

Principle

Credit-card operations can involve multiple economically and legally distinct components.

Relevance

Although primarily a taxation dispute, the case is useful for understanding the legal structure of:

• credit-card services;
• banking arrangements;
• interchange-related activities;
• merchant/payment relationships.

15. Case Law 9 — Awaz v. RBI, NCDRC, 2008 — Historical Position

Before the Supreme Court's 2024 decision, the NCDRC had held that charging credit-card interest above 30% per annum amounted to an unfair trade practice and also objected to certain forms of penal-interest capitalization.

But there is an important qualification

This NCDRC ruling was subsequently set aside by the Supreme Court in Hongkong & Shanghai Banking Corporation Ltd. v. Awaz.

Therefore, it should be cited only as historical background, not as the current governing rule.

16. Unauthorized Transaction Dispute — Legal Test

A practical legal analysis can follow these questions:

Step 1 — Was the transaction authorized?

Ask:

• Did the cardholder make it?
• Did the cardholder permit someone else?
• Was the card stolen?
• Was the transaction online?

Step 2 — Was there customer negligence?

For example:

• OTP disclosed?
• PIN disclosed?
• CVV disclosed?
• Card credentials shared?

Step 3 — Was the bank negligent?

Examples:

• inadequate security;
• failure to block after notification;
• failure to investigate;
• failure to follow RBI directions.

Step 4 — When was the transaction reported?

The reporting date can determine liability.

Step 5 — Can the bank prove customer liability?

The RBI framework places this burden on the bank.

17. Billing Disputes

A cardholder may dispute:

• duplicate billing;
• incorrect amount;
• transaction never received;
• wrong merchant;
• unauthorized EMI;
• cancelled transaction still appearing;
• refund not credited;
• interest calculated incorrectly.

The cardholder should preserve:

• card statement;
• transaction alert;
• merchant invoice;
• cancellation/refund confirmation;
• emails;
• SMS;
• complaint number;
• bank correspondence.

18. Merchant Disputes

A credit-card purchase may generate a dispute between the customer and merchant.

Examples:

Goods not delivered

The customer paid but never received the goods.

Defective goods

The product was delivered but defective.

Cancelled service

A hotel, airline, subscription or service was cancelled but money was not refunded.

Duplicate charge

The merchant charged twice.

The cardholder may have contractual or consumer remedies against the merchant, while the bank/card issuer may separately have obligations concerning the card transaction.

19. Interest and Late-Payment Disputes

Credit-card statements may contain:

• annual percentage rate/interest;
• late-payment charges;
• cash-advance charges;
• finance charges;
• GST/taxes;
• over-limit charges;
• EMI conversion charges.

After Hongkong & Shanghai Banking Corporation Ltd. v. Awaz, courts and consumer fora should not simply impose an arbitrary 30% ceiling on credit-card interest contrary to the applicable regulatory and contractual framework.

The correct inquiry is instead:

What did the contract provide, what did the applicable RBI framework permit/require, and were the charges properly disclosed and applied?

20. Credit Card and CIBIL/Credit Reporting Disputes

A dispute can become more serious if the bank reports a disputed debt to a credit-information company.

Potential issues include:

• wrongful default reporting;
• failure to update repayment;
• reporting a fraudulent transaction as customer's debt;
• failure to correct inaccurate information.

Possible remedies may include:

• correction of the credit report;
• compensation where legally established;
• injunction/declaration;
• regulatory complaint;
• consumer remedy where maintainable.

The important principle is:

A genuinely disputed or fraudulent transaction should not automatically be treated as an admitted consumer debt merely because it appears on a card statement.

21. Defences Available to Banks

Banks may argue:

1. Customer authorized the transaction

Evidence may include authentication records.

2. Customer disclosed credentials

This may establish customer negligence.

3. Delay in reporting

The bank may rely on applicable RBI rules concerning delayed reporting.

4. Contractual authorization

The customer accepted the card's terms and conditions.

5. Transaction was properly authenticated

The bank may produce transaction logs.

6. Dispute is against merchant

Where the issue concerns quality or delivery rather than unauthorized payment, the bank may distinguish the merchant dispute from the banking service.

7. Limitation

A claim brought beyond the applicable limitation period may be barred.

22. Defences Available to Cardholders

Cardholders may argue:

• transaction was unauthorized;
• card was stolen;
• no OTP/PIN was disclosed;
• transaction was reported immediately;
• bank failed to investigate;
• bank failed to comply with RBI requirements;
• amount was already paid;
• duplicate billing occurred;
• refund was not credited;
• interest was incorrectly calculated;
• contractual terms were not properly disclosed;
• disputed debt was wrongly reported;
• bank failed to establish customer negligence.

23. Consumer Protection Dimension

A credit-card holder may potentially approach consumer authorities where the bank's conduct constitutes a deficiency in service or other actionable consumer-law violation.

Examples:

• failure to investigate fraud;
• wrongful charges;
• failure to reverse unauthorized transactions;
• improper service;
• failure to provide contracted services.

However, not every disagreement over a contractual banking term constitutes a consumer-law violation. The Supreme Court's Awaz decision is especially important concerning attempts to have consumer fora rewrite banking-interest terms.

24. Civil Remedies

Depending upon the circumstances, a cardholder may seek:

A. Declaration

That the disputed amount is not legally payable.

B. Injunction

Restraining wrongful recovery action.

C. Refund

Recovery of unauthorized amounts.

D. Compensation

For legally recognised loss caused by deficiency or wrongful conduct.

E. Correction

Correction of account statements and credit records.

F. Interest

Interest on amounts wrongfully withheld, where legally justified.

25. Regulatory Remedies

A cardholder may also use regulatory mechanisms such as:

1. bank's internal grievance mechanism;
2. RBI-regulated complaint mechanisms;
3. Banking Ombudsman framework where applicable;
4. consumer commissions;
5. civil courts;
6. criminal authorities in cases of fraud.

The correct forum depends upon the nature of the dispute and applicable law.

26. Important Distinction: Unauthorized Transaction vs Merchant Dispute

27. Credit Card Fraud — Evidence

Important evidence includes:

• transaction date and time;
• transaction location;
• IP/device records where available;
• OTP records;
• SMS alerts;
• email alerts;
• authentication records;
• card-blocking records;
• customer complaint;
• police complaint;
• bank investigation report;
• CCTV footage where relevant;
• merchant records;
• statement of account.

In a dispute, documentary evidence can be more important than merely asserting:

“I did not make this transaction.”

28. Practical Example

Suppose ₹80,000 is charged to a person's credit card without authorization.

The cardholder notices the transaction and immediately reports it.

The bank says:

“The transaction was authenticated, so you are liable.”

The proper legal analysis is not simply:

Authentication = customer liability.

Instead, the questions are:

1. Was the transaction actually authorized?
2. Was the cardholder negligent?
3. Were credentials shared?
4. Was there third-party fraud?
5. When was the transaction reported?
6. What RBI provisions applied at the relevant time?
7. Can the bank prove customer liability?

The RBI framework specifically places the burden of proving customer liability on the bank.

29. Best Procedure for a Cardholder

When an unauthorized transaction occurs:

Immediately

1. Block the card.

Next

2. Notify the bank through an official channel.

Then

3. Obtain a complaint/reference number.

Also

4. Dispute each transaction individually.

Preserve

5. Save SMS, emails and statements.

If fraud is suspected

6. File an appropriate cybercrime/police complaint.

Finally

7. Escalate through the bank's grievance mechanism and appropriate regulatory/consumer forum if unresolved.

The RBI framework requires banks to maintain 24×7 mechanisms for reporting unauthorized transactions and card loss/theft.

30. Key Legal Principles from the Case Law

Principle 1

Unauthorized transactions are not automatically the customer's liability.

Principle 2

Customer negligence can affect liability.

Principle 3

Prompt reporting is extremely important.

Principle 4

The bank bears the burden of proving customer liability under the RBI unauthorized-transaction framework.

Principle 5

Banks cannot automatically rely upon the existence of a transaction entry as conclusive proof of authorization.

Principle 6

Contractual credit-card terms remain important.

Principle 7

Consumer fora cannot simply rewrite banking contracts or impose an arbitrary interest ceiling contrary to the applicable regulatory framework.

Principle 8

RBI regulatory directions must be considered when determining bank/customer liability.

Principle 9

The applicable regulatory framework depends upon the date of the transaction.

Principle 10

Merchant disputes and unauthorized-transaction disputes must be analytically distinguished.

31. Important Case-Law Table

The recent decisions reinforce that credit-card disputes are highly fact-sensitive, especially where unauthorized transactions are alleged.

32. Exam-Oriented Definition

Credit Card Disputes are legal disputes arising from the issuance, operation or use of credit cards, including unauthorized transactions, fraudulent charges, billing errors, interest and fee disputes, merchant disputes, contractual disagreements, wrongful recovery and credit-reporting issues.

33. Short Exam Formula

Credit Card Dispute = Authorization + Contract + RBI Regulation + Customer Conduct + Bank Duty + Evidence + Reporting Time + Appropriate Remedy

34. Conclusion

Credit-card disputes occupy the intersection of banking law, consumer protection, contract law, electronic transactions and financial regulation.

The most important modern issue is unauthorized transactions. RBI's framework provides a structured system of zero and limited customer liability, while placing the burden of proving customer liability on the bank.

At the same time, Hongkong & Shanghai Banking Corporation Ltd. v. Awaz has significantly clarified the law relating to credit-card interest: consumer fora cannot simply rewrite contractual banking terms or impose their own interest-rate ceiling merely because they consider the rate excessive.

Thus, the governing approach is:

Protect the genuine cardholder from fraud and banking deficiency, while respecting valid contractual arrangements and the specialised regulatory authority of the RBI.

This balance forms the foundation of modern Credit Card Dispute Law in India.
