1. What is Autonomy Principle?

Art 4 and Art 5 UCP 600 + Art 4 eUCP + Spanish Jurisprudence:

A documentary credit, by its nature, is a transaction separate from the sale or other contract on which it may be based. Banks are in no way concerned with or bound by such contract, even if reference is included. Likewise, undertaking of bank to honour is not subject to claims by applicant resulting from relationship with beneficiary.

In Spanish: Principio de autonomía e independencia del crédito documentario.

Three contracts are independent:

1. Contrato subyacente - Sale contract Buyer-Seller
2. Contrato de crédito documentario - Applicant - Issuing Bank
3. Contrato de pago - Issuing Bank - Beneficiary - This is abstract and autonomous

Bank pays if documents comply on their face, even if goods are defective, non-existent, or sale contract is void.

Spanish Legal Basis:

• Not regulated in Código de Comercio - Atypical contract
• Art 1255 CC - Freedom of contract
• UCP 600 incorporated by reference - Considered usos de comercio under Art 2 CCom
• Art 1170 CC - Payment formalities
• Jurisprudence creates law: Tribunal Supremo STS 26/06/1986, 29/11/1991 as founding cases.

2. The Classical Rule in Spain

STS 29 de Noviembre de 1991 - RJ 1991/8574 - First Supreme Court case on autonomy

Facts: Spanish importer opened LC for machinery from Germany. Goods were scrap. Buyer asked bank to stop payment. Bank had already paid against compliant documents.

Held: Tribunal Supremo: Bank must pay if documents are formally compliant. Defect of goods is irrelevant. Autonomy is absolute. Buyer's remedy is against seller, not bank. "El banco examina documentos, no mercancías"

This was absolute autonomy doctrine until 2000.

3. Limits to Autonomy - When Spanish Courts Break Autonomy

Spanish law does NOT accept absolute autonomy like English law. Art 7 CC - Abuse of Right - and Art 11 LOPJ allow limits. There are 5 established exceptions:

Exception 1: Fraude Manifiesto y Notorio - Fraud Exception

The most important limit.

Doctrine: If beneficiary presents documents fraudulently, knowing they are false, and bank knows or fraud is evident without investigation, bank must not pay.

Spanish Leading Cases:

A. STS 27 de Junio de 2000 - RJ 2000/5910
Facts: Beneficiary presented Bill of Lading for goods that never existed. Created false BL by collusion with carrier. Issuing bank (Banco Central Hispano) had telex from carrier saying BL false. Still paid, then claimed reimbursement from applicant.
Held: Supreme Court: Autonomy has limit in fraude manifiesto. If fraud is evident to bank before payment without needing investigation of underlying contract, bank must refuse payment. Bank who pays despite manifest fraud loses right of reimbursement against applicant under Art 1727 CC mandate rules. This adopts Sztejn v J Henry Schroder Banking Corp (NY 1941) doctrine into Spanish law.

B. STS 5 de Julio de 2007 - STS 756/2007
Facts: Export of oranges. Documents showed shipment, but goods were rotten and documents back-dated. Buyer obtained evidence of fraud before payment and notified bank.
Held: Tribunal Supremo reaffirmed: Fraud exception applies only if:

1. Fraud comes from beneficiary himself, not third party
2. Fraud is about documents, not quality of goods
3. Fraud is manifiesto - evident prima facie, without deep investigation, and bank has knowledge before payment.

If fraud is about goods quality (worse quality), autonomy prevails.

C. STS 17 de Marzo de 2004 - RJ 2004/1920
Spanish importer of Chinese textiles. BL showed shipment, but containers empty. Buyer sought injunction to stop payment.
Held: Court denied injunction. Fraud about goods, not documents. Documents were real BL issued by real carrier. Autonomy prevails. Distinction: Fraud in documents vs fraud in transaction.

Spanish courts are stricter than US - require documentary fraud, not just underlying fraud.

Exception 2: Ilicitud de Causa - Illicit Underlying Contract

STS 10 de Febrero de 2010 - RJ 2010/1259

Facts: LC opened for import of goods that were contraband - violation of Spanish customs law and embargo. Underlying sale void for illicit causa under Art 1275 CC.

Held: If underlying contract has illicit causa known to beneficiary and contrary to public policy, and LC is instrument to execute illicit contract, autonomy cannot protect it. Bank can refuse payment if illegality is evident and affects international public order. Based on English case Mahonia Ltd v JP Morgan Chase[2004]

Limit: Must be illegality that is obvious and international - drug trafficking, arms embargo, money laundering.

Exception 3: Nulidad Radical del Crédito por Falta de Causa

If LC itself has no causa - e.g., issued without applicant mandate, or without consideration.

STS 20 de Julio de 2006 - RJ 2006/6548
Bank issued LC without proper consent of applicant company board. Applicant claimed nullity of LC for falta de causa under Art 1261 CC.
Supreme Court held: Relationship bank-applicant is mandate. If mandate void, bank cannot claim reimbursement, but if bank already paid in good faith to bona fide beneficiary, payment is valid due to autonomy. Applicant's remedy is against bank for breach of mandate, not to stop payment.

Exception 4: Abuso de Derecho - Art 7.2 CC - Unjust Calling of Guarantee

When beneficiary calls LC knowing he has no right to payment under underlying contract, even if documents comply.

STS 12 de Marzo de 2015 - STS 108/2015 - Very important for practice

Facts: Construction contract with LC as guarantee. Seller delivered 10% of goods, but presented documents for 100% and claimed payment. Documents compliant - required only shipping documents, not proof of quantity.

Held: Supreme Court imported English Edward Owen Engineering Ltd v Barclays Bank International doctrine. Even if documents comply, if beneficiary's call is abusive - knowingly demanding what is not due under underlying contract - and bank has clear evidence before payment, payment can be enjoined as abuse of right under Art 7 CC. Court granted medida cautelar to stop payment.[1978]

Test established: Abuse requires:

1. Beneficiary's lack of right is clear and undisputed
2. Evidence is liquid, not requiring complex trial
3. Immediate payment would cause irreparable harm

Exception 5: Medidas Cautelares - Injunction to Stop Payment

Spanish Procedural Law allows medida cautelar to stop LC payment under LEC Art 721.

Requirements per Audiencia Provincial de Barcelona 28/09/2018 - SAP B 8922/2018:

1. Fumus boni iuris: Strong prima facie fraud
2. Periculum in mora: Payment will occur before trial
3. Caución: Applicant must post bond to indemnify beneficiary if injunction wrong.

Spanish courts are reluctant: Must prove fraude manifiesto, not just dispute.

4. Comparative Case Law Spanish Courts Cite

Spanish Tribunal Supremo systematically cites:

Sztejn v J. Henry Schroder Banking Corp 177 Misc 719 (NY Sup Ct 1941) - Founding fraud exception - false documents.

United City Merchants v Royal Bank of Canada 1 AC 168 - House of Lords - Lord Diplock: Fraud exception is narrow - only fraud by beneficiary, not by third party carrier. Spanish STS 2000 adopts this.[1983]

Edward Owen Engineering Ltd v Barclays Bank International 1 QB 159 - Demand under performance guarantee with no right. Adopted in Spain STS 2015.[1978]

Banco Santander SA v Bayfern Ltd - English case on strict compliance.[2000]

6. Practical Advice for Spanish Banks and Importers

For Banco Emisor in Spain:

1. Never investigate underlying goods - examine documents only under UCP 600 Art 14 - strict compliance on face.
2. If applicant alleges fraud, demand prueba líquida - telex, email from carrier, admission - before refusing. Otherwise you breach UCP and lose reimbursement.
3. If fraud manifest, you must refuse and notify immediately under Art 16 UCP.
4. File consulta to applicant but do not await authorization if fraud manifest - you have independent duty.

For Ordenante wanting to stop payment:

1. Do not go to bank, go to Juzgado Mercantil for medida cautelar under LEC 721 - need fumus of fraude manifiesto en documentos.
2. Provide caución 100% of LC value - Spanish courts require high bond.
3. You must prove fraud in documents, not just breach of sale contract - bring carrier declaration that BL false.

Article 7 CC is your weapon: Spanish law is more flexible than English law because Art 7 abuse of right allows court to stop abusive call even without classic documentary fraud, if injustice is clear. English law after Alternative Power Solution v Central Electricity Board UKPC is much stricter.[2014]
