1. The Four Corner Model

Originator / Service User: Merchant, utility, lender who wants to collect. Must be sponsored by a bank.
Sponsor Bank / Originator's Bank: Vets originator, holds originator account, submits file to BACS / NACH / SEPA CSM.
BACS / NPCI NACH / SEPA - The Scheme: Rule maker. Pay.UK runs BACS in UK, NPCI runs NACH in India, EPC runs SEPA.
Paying Bank / Payer's PSP: Debtor's bank. Must debit if valid mandate, and refund under Guarantee.

Coordination fails at 3 points: Mandate creation, Collection, and Refund/Indemnity.

2. Legal Framework

• UK: Payment Services Regulations 2017, BACS Service User's Guide and Rules, Direct Debit Guarantee - unconditional immediate refund by paying bank if error.
• EU: PSD2 Art 62, 62, 71-73 - Payer entitled to refund within 8 weeks for authorized, 13 months for unauthorized. SEPA Direct Debit Core Rulebook.
• India: RBI Circular on Customer Protection - Limiting Liability 06.07.2017, NACH Procedural Guidelines by NPCI, E-mandate Framework 2020 - zero liability extended to e-mandates, mandate validation by destination bank.

3. Core Conflicts

Conflict 1: Valid Mandate vs No Mandate - Who proves?

Originator says: "Customer gave mandate on website." Bank says: "We never received ADDACS/mandate image."

Under NACH - If bank cannot produce mandate, bank is liable to refund. Under BACS, originator must retain mandate for 7 years.

Case Law:

a) MSC v BCP Bank - CJEU Case C-295/18
MSC Shipping discovered its account was debited for 3 years by direct debits to a third party with whom it had no relationship and without authorization. BCP Bank confirmed no authorization.[2019]

Held: Under Art 62 PSD, payer entitled to reimbursement for unauthorized debits up to 13 months from notification. Bank must reimburse immediately, then bank can claim against originator's bank. Paying bank cannot refuse saying originator is at fault. Coordination burden is on bank network, not customer.

This established paying bank first, interbank recovery later.

b) ICICI Bank Ltd & Anr vs Sarita Vashisht & Anr (NCDRC, 12 Oct 2017) - Indian Originator Fault Case
Remitter wrongly mentioned beneficiary account number. Money credited to wrong account. Consumer fora blamed beneficiary bank.

Held NCDRC: Fault for wrong credit was upon remitter/originator. Orders of District/State fora perverse as they did not examine sender/originator role. Originator bank must verify account name vs number under RBI guidelines. Originator liable for failed coordination.

Conflict 2: Indemnity Claim - Paying Bank vs Originator

Under UK Direct Debit Guarantee:
If payer claims error, paying bank must give full and immediate refund. Then paying bank raises Direct Debit Indemnity Claim (DDIC) against originator's sponsor bank via BACS. Sponsor bank debits originator.

Originator can dispute indemnity via Indemnity Claim Dispute.

Case Law:

c) Financial Ombudsman Service DRN6323122 - Barclays Case
Employee claimed employer debited after employment ended. Barclays as paying bank allowed payment. Employer (originator) said mandate valid.

Ombudsman: Barclays correctly allowed indemnity. Under Direct Debit Scheme Rules, once payer denies mandate, paying bank must refund. Originator's remedy is civil claim against payer, not to force bank coordination to reject refund. Indemnity is bank-to-bank, not payer-to-originator.

d) Direct Debit Indemnity Claim Process - BACS Rules Challenge
In BankAccountAdvice.co.uk - Originator Disputes Indemnity, originators often dispute saying "customer had contract". BACS Rules: Originator cannot challenge indemnity on basis of underlying contract dispute. Only challenge allowed is "payer was not entitled to refund" - e.g., advance notice given, mandate valid. Underlying goods/services dispute is irrelevant - similar to bank guarantee independence principle.

This creates tension: Originator thinks it has right to collect, bank must still honor Guarantee.

Conflict 3: Sponsor Bank vs Originator - Due Diligence Failure

Sponsor bank is responsible for vetting originator.

e) RBI E-mandate and NACH Disputes - Indian Cases

Allahabad High Court - Burden to Prove Customer Liability Lies on Bank (2024) Livelaw
Under RBI Circular 06.06.2017 Customer Protection, burden to prove customer liability for unauthorized electronic debit lies on bank. Bank must show IP, password modification, beneficiary addition by customer. If bank cannot produce e-mandate log, bank fully liable.

Chandigarh District Commission - Standard Chartered Bank Liable March 2024
Unauthorized debit of Rs 2.6L. Bank argued customer shared OTP. Commission held: Bank ought to reverse unauthorized transactions if informed within 3 days under zero liability. Bank failed to produce e-mandate validation from NACH. Originator's failure to coordinate mandate check makes both originator and paying bank jointly liable.

RBI Rule on NACH Returns: NPCI has set return codes: "Mandate not received", "Account closed", "No such account". If sponsor bank presents without mandate, paying bank returns and penalty on sponsor bank.

Conflict 4: SEPA - Cross Border Coordination Failure

f) Verein für Konsumenteninformation v Deutsche Bahn AG C-28/18 - SEPA Discrimination Case
Deutsche Bahn refused SEPA direct debit if payer not resident in Germany. Austrian consumer body sued.

Held CJEU: Art 9(2) Regulation 260/2012 prohibits IBAN discrimination. Payee must accept any SEPA account. Originator cannot force local account. Bank coordination must be SEPA-wide, originator must coordinate with any paying bank in SEPA.

Risk: Originator faces higher R-transaction risk for foreign accounts, but cannot refuse.

4. Why Conflicts Happen - Summary

5. How Courts Resolve

1. Paying Bank Pays First: Under PSD2 and Direct Debit Guarantee, customer gets immediate refund. Interbank recovery is separate. Customer should not suffer from originator-bank coordination failure.
2. Originator Cannot Resist Indemnity on Contract Grounds: Dispute about goods/services is separate civil suit. Direct debit indemnity is independent, like demand guarantee.
3. Burden of Proof on Banks: To prove mandate, originator/sponsor must produce signed mandate, e-mandate audit trail with IP, Aadhaar eSign, or UMRN in NACH.
4. Sponsor Bank Vicariously Liable: If originator disappears, sponsor bank bears loss and must have collateral.

Best Practice for Originators to Avoid Conflict:

• Use e-mandate with Aadhaar eSign / net banking authentication, not paper
• Give 5-day advance notice with amount variance as per BACS/NACH rules
• Keep mandate proof for 7 years / as per NPCI 10 years
• Implement BACS AUDDIS or NACH mandate management system, not manual Excel.
