1. Core Legal Framework

a) Autonomy Principle - UCP 600 Articles 4 & 5
An LC is independent from the underlying sale contract. Banks are not concerned with or bound by the sale contract even if the LC refers to it. You cannot refuse payment because goods are bad quality, delayed, or contract is breached. That is buyer's risk.

b) Strict Compliance - UCP 600 Articles 14-16
Banks must examine documents strictly on their face. If documents comply, they must pay. If there is discrepancy, they may refuse, but must do so within 5 banking days with all discrepancies listed.
Banks cannot refuse payment based on quality disputes if documents comply. And as per Article 7, bank's obligation is documentary, not goods inspection.

c) Irrevocability
Under UCP 600, all LCs are irrevocable unless agreed otherwise. They cannot be cancelled or modified without consent of all parties.

2. Risk Taxonomy in Documentary Trade Finance

1. Applicant Risk: Buyer defaults, issuing bank cannot get reimbursement.
2. Beneficiary / Fraud Risk: Fake documents, non-existent shipment, over-invoicing, round-tripping.
3. Issuing Bank Risk: Credit risk on issuing bank for confirming/nominated bank.
4. Documentary Risk: Discrepancies, non-documentary conditions, expired LC, late shipment.
5. Country / Sanctions Risk: Sanctions, exchange controls, FEMA / RBI violation.
6. Operational Risk: Wrong field in MT700, failure to catch fraud, mis-examination.
7. Legal Risk: Injunction restraining payment, conflicting laws.

3. Risk Controls Across Lifecycle - What Banks Actually Do

A. At Issuance - Applicant Side

• Credit approval, LC limit, margin money / cash collateral, FEMA declaration.
• KYC, Trade Based Money Laundering check: Price check vs market, dual-use goods, related party.
• Sanctions screening: Applicant, beneficiary, vessel, ports, origin of goods - OFAC, EU, UN, RBI alert list.
• Precise LC drafting: Avoid non-documentary conditions. As per UCP 600 Art 14(h) - If a credit contains a condition without stipulating the document to indicate compliance, banks will deem such condition as not stated. Use ISBP 745 for document wording.
• RBI Controls: AD Bank to check current account transactions, ODI/FDI compliance, ensure BoE, RCMC, Import Export Code.

B. At Advising / Confirmation

• Verify authenticity of SWIFT MT700 via RMA, check for alterations.
• Confirming bank takes issuing bank risk - needs counterparty limit, country limit.
• Never confirm for high-risk country bank without cash cover.

C. At Document Examination - The Critical Control

• 5-Day Rule + One Notice: All discrepancies must be listed in one refusal notice via SWIFT MT734.
• ISBP 745 Checklist: Invoice, Packing List, Transport document (B/L must show on-board, clean, freight prepaid/collect), Insurance (110% of CIF), Certificate of Origin, Inspection.
• Red Flags: Container number mismatch, vessel age >25 years, last minute B/L with no tracking, photocopied transport docs, back-dated documents, circular trade.
• No Goods Inspection: Bank does not open container. Your only shield is document wording.

D. At Payment / Negotiation

• Control for negotiation without recourse: Under UCP 600 Art 12, if nominated bank finds complying presentation and negotiates, it cannot get recourse to beneficiary. So negotiate only if you are comfortable with issuing bank risk.
• Hold documents under approval, reserve, or indemnity only with proper risk approval.

4. Case Laws - Where Controls Failed

Indian Supreme Court - The Twin Exception Doctrine

Indian courts have consistently held: Courts ought not to grant injunction to restrain encashment of bank guarantees or LCs. Two exceptions only: (i) Fraud and (ii) Irretrievable damage.

This was settled in:

1. United Commercial Bank v. Bank of India (1981) 2 SCC 766
Landmark. SC held LC is independent contract. Irrevocable LC cannot be interfered with except on ground of fraud. Objections to underlying contract irrelevant.

2. Federal Bank Ltd. v. V.M. Jog Engineering Ltd. (2001) 7 SCC 158
SC restated: injunction can be issued only if plaintiff prima facie establishes fraud of egregious nature and that bank had notice of such fraud, plus irretrievable injustice. Mere allegation of fraud is not enough.

3. U.P. State Sugar Corporation v. Sumac International Ltd. (1997) 1 SCC 568 & Svenska Handelsbanken v. Indian Charge Chrome (1994) 1 SCC 502
Reiterated that confirmed bank guarantee / irrevocable LC cannot be interfered with unless established fraud or irretrievable injustice involved. Irretrievable injury was defined with reference to US case Itek Corp. v. First National Bank of Boston, 566 Fed Supp 1210 - injury that cannot be compensated in money, e.g., losing entire project/business in a foreign country.

4. UBS AG v. State Bank of Patiala (2006) 5 SCC 416
Most important for fraud exception in India. Facts: Fraud by beneficiary companies on STC. STC alleged fraud after Swiss bank had already negotiated LC.
SC held: For fraud exception to apply, beneficiary's fraud must be to the knowledge of the bank before it made payment. If fraud detected after negotiation, no triable issue. Applying these principles, SC said if fraud had been detected earlier and bank put on caution prior to making payment, case might be different. This is why banks need a real-time fraud alert mechanism to issuing bank.

5. Hindustan Steelworks Construction Ltd. v. Tarapore & Co. (1996) 5 SCC 34
Reaffirmed principle: Bank guarantee or irrevocable LC cannot be interfered with except in case of fraud.

6. United Bank of India Ltd. v. Nederlandsche Standard Bank - Calcutta High Court, 8 June 1961
Early Indian case on strict compliance. Court delved into interpretation and compliance of LC. Established that recovery depends on exact compliance, not substantial compliance.

International Landmark Cases - Origin of Doctrine

7. Sztejn v. J. Henry Schroder Banking Corp. (NY Supreme Court 1941)
First fraud exception. Shipment was rubbish instead of bristles. Court held fraud that vitiates entire transaction allows bank to refuse.

8. United City Merchants v. Royal Bank of Canada AC 168 (House of Lords)
Lord Diplock: Fraud exception applies only to fraud by beneficiary, not by third party (e.g., freight forwarder falsifying B/L date) unless beneficiary knew. Narrow interpretation.[1983]

9. Letters of Credit Court of Appeal Case - CACIB
English Court of Appeal clarified scope of fraud exception, letters of indemnity. Held that widening fraud exception would significantly undermine whole system of documentary credits.

5. Practical Control Checklist for Your Trade Desk

Before Issuing:

•  LC text reviewed by Trade Ops - no "quality acceptable to buyer" type conditions
•  Sanctions check on all 6 points: Applicant, Beneficiary, Notify, Ports, Vessel, Goods
•  Credit approval + margin earmarked

At Negotiation/Import Bill:

•  Docs received within 21 days of shipment + within LC expiry
•  B/L verified on shipping line site, container tracking, not CLC (combined transport vs port to port)
•  Invoice value = draft value = LC value tolerance (+/-5% if not prohibited)
•  Insurance date on/before B/L date, covers 110%

Fraud Controls:

•  Price inflated >30% vs market? Flag TBML
•  Related party applicant-beneficiary? Enhanced due diligence
•  Photocopy B/L, no original? Refuse.

In practice, Indian banks lose cases because they grant injunctions on commercial disputes. As settled law, alleging fraud by the beneficiary companies upon itself is not enough unless you prove bank knew before payment and fraud is egregious.
