Maritime Letters of Indemnity: International Regulation, CMI Conferences, Clean Bills of Lading, and Fraud Risk

Maritime Letters of Indemnity: International Regulation, CMI Conferences, Clean Bills of Lading, and Fraud Risk

Letters of Indemnity (LOIs) have been used in international shipping for more than a century to overcome practical difficulties created by Bills of Lading (B/Ls). Their commercial usefulness has always been accompanied by legal risk. An indemnity may allow a transaction to proceed, but it can also weaken the reliability of a Bill of Lading (B/L), prejudice buyers and banks, affect insurers, and expose carriers to liabilities that would not arise if the shipping document accurately reflected the cargo and the agreed carriage.

The international maritime community confronted this problem long before delivery without Original Bills of Lading (B/Ls) became as widespread as it is in modern trade. During the first half of the twentieth century, the principal concern was the use of Letters of Indemnity (LOIs) to persuade carriers to issue clean Bills of Lading (B/Ls) despite reservations about the quantity, condition, packaging, or apparent state of the cargo.

The Comité Maritime International (CMI) examined the issue repeatedly, most notably at the 1927 Amsterdam Conference and the 1955 Madrid Conference. Those debates reveal a persistent conflict between documentary certainty and commercial flexibility. They also show that the problem affected far more than shipowners and shippers. Banks financing international sales, cargo insurers, P&I interests, receivers, consignees, and later holders of Bills of Lading (B/Ls) all depended on the reliability of the transport document.

Why Clean Bills of Lading Became the Central Concern

A clean Bill of Lading (B/L) is commercially important because it contains no clause expressly declaring that the goods or their packaging are in defective apparent condition. Buyers and banks may rely on that documentary appearance when deciding whether the seller has performed the sale contract and whether payment should be made.

The difficulty arises when the carrier believes that the cargo should be claused while the shipper requires a clean document to satisfy the sale contract or Letter of Credit (LC). A Letter of Indemnity (LOI) can then be offered to persuade the carrier to issue the clean Bill of Lading (B/L) and transfer the financial consequences back to the shipper if a claim later arises.

This arrangement can arise in a bona fide disagreement over whether the apparent condition justifies clausing. It becomes fundamentally different where carrier and shipper know that the clean Bill of Lading (B/L) is false and use the indemnity to conceal the true state of the goods from parties who will rely on the document.

Delivery Without Original Bills Was an Earlier but Smaller Problem

Delivery without production of the Original Bill of Lading (B/L) was already known during the first half of the twentieth century, but the source material indicates that it was less prominent than the clean-bill problem. Cargo and documents did not encounter the same timing mismatch seen in many modern string trades.

Early Lloyd's Law Reports nevertheless contain disputes involving delivery without production of the Bill of Lading (B/L), including Strathlorne Steamship Co. v Andrew Weir & Company, Nederlandse Handel v Strathlorne Steamship Co., National Bank of Turkey v Edward & Son, and Stewart & Co. Limited v Lofthouse & Co.

In some cases, carriers sought recovery under a Letter of Indemnity (LOI). In others, recovery was pursued without an express indemnity. These authorities show that contractual recourse for departure from normal Bill of Lading (B/L) presentation had already become part of maritime law before the CMI made clean Bills of Lading (B/Ls) an international policy issue.

Early Belgian Decisions Distinguished Fraud from Good Faith

Before the Amsterdam Conference, Belgian courts had already considered indemnities connected with cargo condition and clean shipping documents.

A judgment delivered in Antwerp on 6 September 1907 treated shipper and master as having committed an illicit and fraudulent act where an indemnity was used in circumstances involving cargo that was not in apparent good order and condition at shipment.

Later Belgian judgments during the 1920s were less absolute. They recognised that use of a Letter of Indemnity (LOI) was not necessarily unlawful and that an undertaking made in good faith could require the shipper to indemnify the master. Other decisions refused enforcement where the obligation was founded on an illicit cause.

The Belgian cases therefore exposed the distinction that would dominate later international discussions: a bona fide indemnity used to resolve uncertainty could stand on a different legal footing from an arrangement designed to support deception.

French Courts Adopted a Similar Distinction

French commercial courts also distinguished between legitimate and fraudulent indemnity arrangements. Decisions from Marseille and Bordeaux were reported as recognising the validity of Letters of Indemnity (LOIs) issued in good faith between carrier and shipper, while fraudulent undertakings were treated as ineffective.

This approach did not remove every uncertainty, but it established an important policy principle. The law did not necessarily need to prohibit every indemnity merely because it affected a Bill of Lading (B/L). The greater concern was an agreement whose purpose was to mislead a third party relying on the document.

The CMI Began a Long International Examination

From 1927 onward, the CMI spent almost three decades considering how international shipping should respond to the increasing use of Letters of Indemnity (LOIs) for clean Bills of Lading (B/Ls).

The debate involved national maritime law associations, shipowners, bankers, insurers, lawyers, and international commercial organisations. The core concern was the credit and reliability of negotiable Bills of Lading (B/Ls). If a clean document could routinely be issued despite known adverse cargo conditions because a private indemnity existed between carrier and shipper, later holders could no longer rely on the face of the document with confidence.

Why LOI Use Increased After the First World War

By 1927, many maritime law associations considered that use of Letters of Indemnity (LOIs) had increased materially compared with the pre-war period.

The growing use of documentary credits was identified as one reason. When payment increasingly depended on presentation of clean and conforming transport documents, the financial importance of avoiding clausing became greater. Changes in packing methods also created more disputes about apparent condition and the adequacy of packaging.

As documentary standards became more closely connected with payment, sellers had stronger incentives to obtain clean Bills of Lading (B/Ls), even where the carrier had reservations.

The 1927 Amsterdam CMI Conference

The CMI placed Letters of Indemnity (LOIs) against clean Bills of Lading (B/Ls) prominently on the agenda of the Amsterdam Conference in 1927. National maritime law associations were asked to report on the scale of the problem, existing legal treatment, and possible international solutions.

Two broad approaches emerged. One favoured international intervention that would invalidate or otherwise regulate problematic indemnities. The other preferred to preserve the existing legal position and allow the shipping, insurance, banking, and trading markets to develop their own solutions.

The Argument for Commercial Flexibility

Several delegates argued that commerce sometimes genuinely required the flexibility provided by Letters of Indemnity (LOIs). The point was not that knowingly false Bills of Lading (B/Ls) should be tolerated, but that apparent cargo condition can involve honest differences of opinion.

The International Chamber of Commerce (ICC) delegate supported the more cautious status-quo approach associated with the United Kingdom, Germany, Italy, and Norway. A United States delegate likewise recognised that some indemnities could be honest and commercially adequate and argued that abusive cases did not necessarily justify abolishing the instrument altogether.

Fraud Was Condemned Even by Opponents of a Ban

Resistance to an international prohibition did not mean acceptance of fraudulent documentary conduct. The Amsterdam discussions included strong condemnation of knowingly false Bills of Lading (B/Ls).

The real disagreement concerned how to distinguish a deliberate fraud from a genuine dispute. A carrier uncertain about whether visible characteristics justify clausing is in a very different position from a carrier that knows cargo is visibly defective and nevertheless agrees to issue a clean Bill of Lading (B/L) so that the seller can obtain payment.

Shipowners Expressed Different Commercial Views

Shipowner representatives did not present a single position. Some regarded Letters of Indemnity (LOIs) as undesirable but occasionally necessary. Others believed abuse was concentrated in particular sectors rather than being a general feature of shipping.

A.P. Moller, then a Copenhagen tramp shipowner, spoke from the perspective of tramp shipping and indicated that abuse had not been a major practical problem in that part of the market. Other shipowners considered that lawyers and legislators should not intervene prematurely and that commercial practice should first be allowed to develop its own corrective mechanisms.

Banks Were Part of the Cause and Part of Any Solution

Several delegates viewed banking practice as one of the forces driving demand for clean Bills of Lading (B/Ls). Banks operating Letters of Credit (LCs) could reject transport documents containing reservations inconsistent with the credit, leaving sellers unable to obtain payment.

A proposal associated with the Chairman of Lloyds Bank suggested that shippers should not induce carriers to issue clean Bills of Lading (B/Ls) where clausing was justified. Instead, bank guarantees could be used to protect against the financial consequences of the reservation so that banks could accept claused documents in appropriate circumstances.

The proposal attempted to move the dispute away from the carrier and toward the seller and banking relationship, where questions of sale-contract conformity and payment more naturally belonged.

Insurance Interests Favoured Strong Controls

Cargo and ship underwriters were also directly concerned. Insurance organisations had criticised the practice of issuing clean Bills of Lading (B/Ls) against private indemnities before the Amsterdam Conference.

Their concern was evidential as well as financial. A false clean Bill of Lading (B/L) could distort the evidence later used to determine when cargo damage arose and who should bear it. An insurer could also discover that facts relevant to policy liability or recovery had been concealed by a private agreement between shipper and carrier.

Three Main Solutions Emerged at Amsterdam

The 1927 discussions produced three principal proposals. The first was to replace shipper-issued Letters of Indemnity (LOIs) with bank guarantees. The second was to establish a system of notification so that cargo underwriters or receivers would be informed when an indemnity had been issued. The third, advanced through the French Maritime Law Association, was to regulate the practice through an international convention.

Each approach attempted to protect confidence in Bills of Lading (B/Ls), but each allocated the burden differently among shippers, carriers, banks, buyers, receivers, and insurers.

Replacing the Shipper's LOI with a Bank Guarantee

The Swedish Maritime Law Association supported a proposal under which the shipper-seller's Letter of Indemnity (LOI) would be replaced by a guarantee issued by the seller's bank in favour of the buyer's bank.

The objective was to leave the Bill of Lading (B/L) factually accurate while transferring the commercial consequences of the reservation into the banking system. The seller and its bank, rather than the carrier, would stand behind the risk that the buyer or buyer's bank might otherwise reject the claused document.

How a Bank Guarantee Would Have Reallocated Risk

The bank providing the guarantee could require collateral or other counter-security from its customer. That would create a direct financial incentive to investigate the transaction and the seller's reliability before supporting a disputed documentary tender.

For carriers, the arrangement offered an important advantage. Shipowners are generally outside the underlying sale dispute concerning whether the commodity satisfies contractual quality specifications. A bank-guarantee model could have reduced pressure on the master to convert a genuine cargo reservation into a misleading clean Bill of Lading (B/L).

Problems with the Bank-Guarantee Proposal

The proposal also had significant drawbacks. Banks might lack the technical knowledge needed to decide whether a cargo-condition reservation was serious or merely reflected a minor difference of opinion. The cost of guarantees and counter-security could make international sales more expensive.

Transactions could also be delayed while banks examined the dispute. Buyers might lose part of their traditional ability to reject non-conforming documents if a bank-backed instrument was used to make a documentary discrepancy commercially acceptable.

Notification to Cargo Underwriters and Receivers

A second solution relied on transparency. British underwriters and shipowners had reportedly developed a system under which receivers and cargo underwriters could ask whether a Letter of Indemnity (LOI) had been issued in connection with the Bill of Lading (B/L).

Lloyd's Agents at the port of shipment could obtain the information through survey procedures. The idea was that a party relying on the clean Bill of Lading (B/L) should not remain unaware that the carrier had received a private indemnity concerning cargo condition.

Notice Could Reduce Blind Reliance on a Clean Bill

If a receiver or insurer knew that an indemnity existed, the clean Bill of Lading (B/L) would no longer be viewed in complete isolation. The notified party could investigate before relying on the transport document.

The system nevertheless left the carrier at the centre of the problem and did not eliminate fraud. It was also of limited benefit to banks unless the information reached the documentary-credit system in a recognised form.

Operational Weaknesses of a Notice System

Delegates identified practical weaknesses. Transshipment could interrupt the information chain because a later carrier might have no knowledge that an indemnity had been issued at the original loadport.

Commercial pressure could also weaken disclosure. A carrier competing for valuable business might have an incentive not to draw attention to a private indemnity. A notification regime therefore depended on consistent conduct by market participants whose commercial interests might not always favour complete transparency.

The French Proposal for an International Convention

The French Maritime Law Association favoured stronger legal intervention. Its report accepted that French jurisprudence could recognise a Letter of Indemnity (LOI) made in good faith, but treated fraudulent undertakings as fundamentally different.

The proposal sought to prevent secret agreements concerning cargo condition from contradicting the Bill of Lading (B/L) on which third parties relied. It contemplated invalidity for private arrangements not reflected in the carriage document and stronger consequences where the indemnity formed part of a fraud against consignees or other third parties.

Why France Favoured International Regulation

The French position was that the commercial convenience of Letters of Indemnity (LOIs) did not justify the danger created for innocent third parties when a clean Bill of Lading (B/L) concealed a contradictory side agreement.

The proposed reform assumed that banks would adapt if the law made truthful cargo reservations unavoidable. Instead of forcing carriers to produce clean documents because banks demanded them, the market would learn to work with justified clauses.

Why an Absolute Ban Could Damage Legitimate Trade

An absolute prohibition could also produce serious commercial problems. Genuine disputes frequently arise over whether goods are in apparent good order and condition. The significance of visible rust, staining, packaging damage, moisture, marks, or other external characteristics may not always be obvious.

If every Letter of Indemnity (LOI) connected with a disputed reservation were automatically void, the law could prevent legitimate transactions from finding a practical solution. The challenge was to distinguish bona fide uncertainty from deliberate concealment.

Shipping Law Alone Could Not Solve the Problem

The French proposal also exposed a structural difficulty. Prohibiting indemnities would not eliminate the seller's need for conforming documents if Letter of Credit (LC) practice still rejected claused Bills of Lading (B/Ls).

Under a CIF (Cost, Insurance, and Freight) sale requiring a clean Bill of Lading (B/L), the seller could still face rejection even if the carrier was legally compelled to record an honest reservation. Any durable solution therefore required cooperation among maritime law, sale-of-goods rules, banking practice, and documentary-credit standards.

Potential Effect on Banks

A prohibition could have increased documentary certainty by reducing the risk that a clean Bill of Lading (B/L) concealed a private indemnity. However, banks would still face the practical question whether to accept a transport document containing cargo-condition reservations.

The assumption that banks would readily accept claused documents once private indemnities were prohibited was uncertain. Banks act under documentary mandates and cannot simply disregard discrepancies because the carrier had good reason to include them.

Potential Effect on Carriers

Carriers could benefit if an international rule discouraged shippers from demanding inaccurate clean Bills of Lading (B/Ls). At the same time, a rigid prohibition could make the carrier the direct battleground for every honest dispute about apparent cargo condition.

Without a recognised mechanism for dealing with borderline cases, masters and owners could face greater commercial pressure rather than less.

Amsterdam Rejected a Universal International Ban

The Amsterdam Conference ultimately declined to establish a uniform international prohibition. The prevailing view was that the problem should continue to be handled by individual countries and by the commercial sectors directly concerned.

The result reflected a widespread belief that the practice involved too many legitimate commercial situations to justify a universal legal ban at that stage. The international problem therefore remained unresolved.

The 1954 Brighton CMI Sub-Committee

The CMI returned to the subject through its sub-committee on claused Bills of Lading (B/Ls), which met in Brighton on 22 September 1954 before the Madrid Conference.

Delegates reported different national approaches. French law could recognise some indemnities and reject others. Sweden had not yet obtained a definitive court ruling. The United States delegation regarded deliberate issue of a false Bill of Lading (B/L) as potentially criminal and supported international regulation. Italian representatives remained sceptical about the need for a convention.

The British Maritime Law Association's Warning

The British Maritime Law Association (BMLA) described increasing commercial pressure on shipowners to issue clean Bills of Lading (B/Ls). A shipper could threaten to move future business to a less cautious competitor if an owner insisted on proper clausing.

Owners sometimes responded by accepting a Letter of Indemnity (LOI). The BMLA criticised this practice because the security could prove worthless if the shipper later lacked the resources to honour the undertaking. The source also records concern that even a local-bank countersignature did not invariably produce reliable recovery.

Commercial Competition Could Produce a Race to the Bottom

The BMLA analysis exposed a broader market problem. A conscientious carrier that insisted on accurate clausing could lose employment to an operator willing to issue clean documents against an indemnity.

If documentary laxity became a competitive advantage, the reliability of Bills of Lading (B/Ls) could deteriorate across the industry. The issue was therefore not merely the private risk assumed by one owner but the collective credibility of maritime documentation.

The BMLA Distinguished Different Types of Cargo Reservations

The BMLA did not treat every reservation as equivalent. Where damage, deterioration, or defects in the goods, packaging, or containers were visible on reasonable external examination at shipment, the Bill of Lading (B/L) should be properly claused.

Where goods were shipped wholly unprotected, the Bill of Lading (B/L) could state that fact directly. Where the carrier considered packing insufficient for the ordinary hazards of an ocean voyage, a marginal clause could record the carrier's view about the adequacy of the packing.

This approach sought to reduce disputes through accurate and specific description rather than forcing every shipment into a choice between a completely clean Bill of Lading (B/L) and a notation that unnecessarily damaged the seller's documentary position.

National Agreements Were Preferred by the BMLA

The BMLA favoured national or industry agreements identifying acceptable types of clausing and the circumstances in which they should be used. Standardisation could help banks and commercial parties understand which reservations were normal and which indicated a significant cargo problem.

If justified clauses became predictable and commercially intelligible, the perceived need for secret Letters of Indemnity (LOIs) could be reduced.

The 1955 Madrid CMI Conference

The CMI again devoted substantial attention to the subject at Madrid in 1955 amid concern that misuse of Letters of Indemnity (LOIs) against clean Bills of Lading (B/Ls) continued to increase.

The conference considered both punitive and commercial solutions. The most severe proposal came from the United States delegation, which sought an international convention criminalising deliberate participation in false negotiable Bills of Lading (B/Ls).

The US Proposal to Criminalise Fraudulent Bills of Lading

The proposed convention targeted knowingly false statements concerning the number of packages or pieces, quantity, weight, or apparent condition of goods shown in negotiable Bills of Lading (B/Ls).

The intended offences extended beyond the person physically signing the document. Those knowingly assisting, procuring, negotiating, or transferring a false Bill of Lading (B/L) for value could potentially be caught.

The proposal also sought to criminalise the act of requesting a carrier or carrier representative to issue a negotiable Bill of Lading (B/L) containing knowingly false cargo information, even if the request was not ultimately accepted.

Why Criminalisation Was Controversial

The proposed regime was controversial because it could potentially involve shipowners, agents, sellers, banks, P&I interests, and others connected with the documentary chain.

Critics questioned whether the number of fraudulent cases justified a new international criminal convention when domestic legal systems already dealt with fraud and related misconduct.

There was also a classification problem. New packing methods, containers, and increasing use of CIF (Cost, Insurance, and Freight) trading created situations in which reasonable parties could disagree about the proper description of apparent cargo condition. A criminal rule needed to avoid treating an honest documentary judgment as deliberate fraud.

Bona Fide Disputes and Fraud Required Different Treatment

The central distinction remained the same as in 1927. If carrier and shipper know that cargo is visibly damaged but deliberately issue a clean Bill of Lading (B/L) so a third party will rely on a false statement, the policy case for refusing enforcement and imposing serious consequences is strong.

If the parties genuinely disagree about whether a condition is material, visible, or sufficient to justify clausing, an absolute prohibition may be excessive. International regulation therefore had to preserve room for honest disagreement without providing cover for deception.

The Proposed Shipper's Supplemental Indemnity

Alongside the criminalisation proposal, the United States delegation proposed a more constructive solution for bona fide disputes: a standard Shipper's Supplemental Indemnity.

The concept did not require the carrier to conceal its reservation. The Bill of Lading (B/L) would remain claused, and a separate document would explain the disagreement and allocate responsibility among shipper, carrier, consignee, indorsee, or other holder.

This was fundamentally different from a secret Letter of Indemnity (LOI) used to obtain a clean Bill of Lading (B/L). The supplemental instrument was designed to preserve transparency.

How the Supplemental Indemnity Was Intended to Operate

The proposed form would reproduce the reservation appearing on the Bill of Lading (B/L) and explain why the shipper nevertheless considered that the sale and financing transaction should proceed.

It contemplated genuine differences of opinion concerning cargo condition, marks, number, quantity, or weight, and situations in which the damage producing the reservation was considered negligible compared with the expense or delay required to remedy it.

The shipper would assume a direct liability toward the consignee, indorsee, or Bill of Lading (B/L) holder for losses connected with the disputed reservation. The carrier would also provide protection toward the documentary holder while preserving recourse against the shipper.

Why the Supplemental Form Was More Transparent

The proposed form addressed one of the central weaknesses of a traditional private Letter of Indemnity (LOI): secrecy.

Instead of presenting a clean Bill of Lading (B/L) while hiding the carrier-shipper disagreement, the supplemental structure would place the reservation and the indemnity mechanism into the documentary transaction itself.

The consignee or holder would know that the carrier had concerns and would receive contractual protection for the consequences. That transparency could reduce the risk of an innocent buyer or bank relying on a statement that the carrier itself did not believe to be accurate.

Potential Benefits for Sellers and Buyers

For sellers, the supplemental form could provide a method of continuing a sale where a cargo reservation was genuinely disputed rather than losing the transaction automatically because the Bill of Lading (B/L) was claused.

For buyers, the system could provide direct compensation rights without depriving them of information about the cargo condition. It might also reduce opportunistic rejection of documents in a falling market where the underlying discrepancy was minor and the buyer was financially protected.

The form would not eliminate deliberate fraud, because parties willing to falsify documents might also try to circumvent a transparent supplemental mechanism.

Potential Benefits for Banks

The supplemental instrument could have increased certainty for financing banks because the cargo reservation would remain visible while defined undertakings supported the documentary transaction.

Instead of paying against a clean Bill of Lading (B/L) that secretly contradicted a private indemnity, the bank would see both the reservation and the financial protection. This could reduce the information imbalance that makes fraudulent clean Bills of Lading (B/Ls) particularly dangerous to Letter of Credit (LC) banks.

Potential Benefits for Carriers

For carriers, the proposed form could discourage unreasonable pressure because the shipper would assume a separate liability toward the Bill of Lading (B/L) holder rather than merely promising privately to reimburse the shipowner.

A recognised form could also help masters and carriers refuse requests falling outside the defined bona fide categories. The carrier could insist that a genuine dispute be documented openly rather than concealed through a private arrangement designed to produce a clean Bill of Lading (B/L).

Financial Backing Was Essential

The supplemental system would only have been as strong as the parties standing behind the undertakings. A promise from an insolvent shipper would provide little practical security. Cargo interests would also need confidence that the carrier could honour its own undertaking.

The source therefore suggests that support from banks and P&I interests would have been important. Financial institutions could countersign or otherwise support the relevant obligations so that the indemnity structure was backed by credible security rather than merely contractual language.

Documentary-Credit Rules Also Needed to Change

The most serious obstacle to the Supplemental Indemnity was banking acceptability. If the Bill of Lading (B/L) remained claused, a bank operating under a Letter of Credit (LC) requiring a clean transport document could still refuse the presentation.

The United States delegation therefore proposed that the International Chamber of Commerce amend its documentary-credit rules so that a credit could expressly permit a claused Bill of Lading (B/L) when accompanied by the recognised Supplemental Indemnity.

Without such a change, the form would not solve the seller's payment problem and would not remove the commercial incentive to obtain a clean document through other means.

Madrid Did Not Produce a Binding Universal Solution

The Madrid Conference did not immediately transform the proposals into a binding international regime. The CMI instead resolved to circulate the United States draft convention and other proposals among national associations for further study and comment.

The subject therefore remained open after 1955 despite almost three decades of international debate.

International Attention Declined After the 1955 Conference

Official attention to Letters of Indemnity (LOIs) decreased in the years after Madrid. The CMI Conferences at Rijeka in 1959 and Athens in 1962 did not give the issue the same prominence.

The problem remained under study, but the international maritime-law agenda moved elsewhere. This decline did not mean that clean-bill disputes or indemnity practices had disappeared.

Brown Jenkinson Gave English Law a Clear Rule

A major legal development came in 1957 when the English Court of Appeal decided Brown Jenkinson & Co. v Percy Dalton (London) Ltd.

The case became the leading English authority concerning an indemnity used to obtain a clean Bill of Lading (B/L) where the carrier knew that the cargo condition required qualification.

Its central significance is that a Letter of Indemnity (LOI) cannot safely be treated as an ordinary commercial risk-allocation device where enforcement would require the court to support deliberate documentary misrepresentation.

Brown Jenkinson Did Not Invalidate Every Maritime LOI

The decision should not be read as declaring all Letters of Indemnity (LOIs) unenforceable. Its force is strongest where the indemnity is connected with a knowingly false clean Bill of Lading (B/L) and the arrangement is intended to mislead persons relying on that document.

A bona fide disagreement over apparent cargo condition remains legally and commercially different from deliberate fraud. This distinction is consistent with the earlier Belgian and French decisions and with the central policy debate running through the Amsterdam and Madrid conferences.

The Hamburg Rules Later Addressed the Problem Expressly

The 1978 United Nations Convention on the Carriage of Goods by Sea, commonly known as the Hamburg Rules, later addressed shipper-carrier guarantee or indemnity arrangements concerning omitted Bill of Lading (B/L) reservations.

The source explains that Article 17 treats such an arrangement as ineffective against third parties where it concerns omission of reservations relating to cargo particulars or apparent condition.

As between carrier and shipper, the arrangement may retain effect in appropriate circumstances, but the carrier loses the right of indemnity where the omission was intended to defraud a third party acting in reliance on the Bill of Lading (B/L).

The provision reflects the same policy line developed during the earlier CMI debates: protect innocent documentary holders while distinguishing genuine commercial disagreements from fraud.

Protection of Third Parties Was the Central Policy Objective

The strongest objection to secret Letters of Indemnity (LOIs) was not simply that they changed the relationship between shipper and carrier.

Those two parties may know the true cargo condition and may agree between themselves how resulting losses should be allocated. The greater danger arises when the clean Bill of Lading (B/L) is transferred to a buyer, bank, consignee, indorsee, or insurer that does not know a contradictory side agreement exists.

The international policy debate therefore focused on preserving confidence for parties outside the indemnity relationship.

Why Banks Were Particularly Vulnerable

A bank financing a sale under a Letter of Credit (LC) deals primarily with documents rather than physically inspecting cargo.

The value of the Bill of Lading (B/L) lies in its ability to provide documentary evidence and security while the goods remain in the carrier's custody. If a clean Bill of Lading (B/L) secretly contradicts a Letter of Indemnity (LOI), the bank may pay against a document that appears to represent cargo in acceptable apparent condition even though carrier and shipper know otherwise.

This explains why banking practice was inseparable from every serious attempt to regulate indemnities connected with clean Bills of Lading (B/Ls).

Why Cargo Insurers Were Also Exposed

Cargo insurers depend on accurate facts when determining whether damage arose before shipment, during the voyage, or after discharge.

A clean Bill of Lading (B/L) obtained through a secret indemnity can distort that evidential picture. If goods were already visibly damaged at shipment but the document records no reservation, the insurer may initially evaluate the claim on a false factual premise.

The indemnity can later become evidence of the parties' knowledge and may affect insurance coverage or recovery proceedings.

Carriers Could Also Become Victims of the Practice

Although the carrier voluntarily accepts the Letter of Indemnity (LOI), the shipowner can still suffer serious consequences.

The carrier may face a direct claim from the lawful Bill of Lading (B/L) holder, prejudice P&I cover, incur substantial legal costs, provide security, and then discover that the indemnifier is insolvent or that the undertaking is unenforceable because the underlying conduct was fraudulent.

A private indemnity can therefore replace documentary and insurance protection with direct credit exposure to the shipper or other indemnifier.

Why Shippers Continued to Seek Clean Bills

Shippers had powerful commercial incentives to preserve clean documentation. A claused Bill of Lading (B/L) could prevent payment under a Letter of Credit (LC), permit rejection under the sale contract, disrupt a string sale, or expose the seller to a falling commodity market.

From the seller's perspective, a Letter of Indemnity (LOI) could keep the transaction moving while transferring liability toward the carrier. The difficulty was that the seller's immediate benefit could prejudice a buyer, bank, or insurer that never agreed to the private arrangement.

Clean Bills of Lading Under CIF Sales

In a CIF (Cost, Insurance, and Freight) sale, documentary obligations can make the cleanliness of the Bill of Lading (B/L) decisive. Where the sale contract or Letter of Credit (LC) requires a clean transport document, a claused Bill of Lading (B/L) can render the tender non-conforming.

This explains why the indemnity problem could not be solved simply by instructing carriers to clause more rigorously. Unless buyers and banks were also prepared to accept justified reservations, sellers would continue to face strong commercial incentives to seek clean documents.

FOB Sales Also Depend on Documentary Accuracy

FOB (Free On Board) sales allocate shipment and carriage responsibilities differently from CIF (Cost, Insurance, and Freight) contracts, but the Bill of Lading (B/L) remains commercially important.

Depending on the contractual structure, the buyer may be more directly involved in nominating the ship or arranging carriage, while the seller remains responsible for placing the contractual goods on board. A clean Bill of Lading (B/L) can still affect proof of shipment, cargo condition, payment, and rights against the carrier.

The Historical Debate Anticipated Modern Shipping Problems

The Amsterdam and Madrid discussions occurred long before electronic trade documents, modern container logistics, instant communications, and today's complex commodity chains.

Yet the essential questions remain familiar: who should bear the risk when commercial performance requires departure from strict documentary procedure, how should innocent third parties be protected, and when does practical flexibility cross the line into deception?

The historical proposals anticipated modern concerns about transparency, bank support, standard forms, insurer involvement, and coordination between shipping law and trade-finance rules.

Accurate Clausing Is Preferable to Concealed Side Agreements

One enduring lesson is that accurate descriptive clausing is often preferable to forcing every transaction into a binary choice between a perfectly clean Bill of Lading (B/L) and commercial failure.

If the transport document records observable facts precisely, the parties can evaluate the significance of the reservation. Standardised clauses can also distinguish visible damage from unprotected cargo, inadequate packaging, or matters the carrier cannot reasonably verify.

Greater precision can reduce pressure to use Letters of Indemnity (LOIs) simply to erase reservations that should properly appear on the Bill of Lading (B/L).

Transparency Is Safer Than a Secret LOI

The Supplemental Indemnity proposal remains conceptually important because it attempted to preserve the reservation rather than conceal it.

A transparent structure allows buyers, banks, consignees, and holders to know that carrier and shipper disagree and to evaluate the accompanying financial protection. A secret Letter of Indemnity (LOI), by contrast, allows a clean Bill of Lading (B/L) to circulate as though no dispute ever existed.

Bank Support Does Not Cure Fraud

The CMI proposals repeatedly considered bank guarantees or countersignatures because an indemnity is only commercially valuable if the responsible party can pay.

A financially strong bank can improve the credit quality of an undertaking, but banking support does not make a fraudulent clean Bill of Lading (B/L) lawful. Creditworthiness and legal enforceability are separate questions.

P&I Support Also Has Limits

P&I involvement can provide guidance on acceptable procedures and forms, but insurance cannot safely be assumed to respond where the member knowingly participates in improper documentary conduct.

The historical opposition of insurance interests to fraudulent clean Bills of Lading (B/Ls) reflects the same principle: a shipowner should not deliberately create a misleading documentary position and assume that mutual insurance will automatically absorb the resulting liability.

Practical Test for a Bona Fide Cargo-Condition Dispute

Where a shipper seeks a clean Bill of Lading (B/L), the carrier should first ask whether the disagreement concerns facts that reasonable parties could genuinely assess differently.

Relevant considerations include whether the alleged defect is externally visible, whether it concerns the goods or packaging, whether loading conditions obstruct inspection, whether the issue relates to quality rather than apparent condition, and whether the proposed wording accurately describes what the carrier can observe.

If the carrier knows that the cargo is visibly damaged and that the proposed clean Bill of Lading (B/L) would communicate a false representation, the matter has moved beyond a bona fide dispute.

Practical Test Before Accepting an LOI

A carrier considering a Letter of Indemnity (LOI) should separate four questions.

First, is the requested act lawful and honest? Second, which third parties may rely on the Bill of Lading (B/L)? Third, will insurance respond if a claim arises? Fourth, is the indemnifier financially capable of meeting the resulting exposure?

If the requested act is knowingly deceptive, stronger wording or better financial security cannot cure that problem. If the other questions are not answered satisfactorily, the indemnity may provide far less protection than its formal wording suggests.

Practical Test for Banks Financing the Transaction

Banks should be alert to any structure in which a Bill of Lading (B/L) may have been presented as clean despite a private dispute or indemnity concerning cargo condition.

Where a Letter of Credit (LC) requires a clean transport document, the bank's documentary mandate should not be confused with an independent judgment about the physical goods. A transparent mechanism for justified reservations can reduce the incentive for false clean documents only if the credit expressly permits that structure.

Practical Test for Buyers and Receivers

Buyers and receivers rely on the Bill of Lading (B/L) not only for delivery but also for information about the apparent condition in which the carrier received the cargo.

A clean Bill of Lading (B/L) obtained against a concealed Letter of Indemnity (LOI) can deprive them of the opportunity to reject non-conforming documents or investigate the cargo before payment.

Where an indemnity forms part of a transparent bona fide arrangement, the buyer should understand the reservation, the scope of the undertaking, and the financial standing of the parties providing protection.

No International Proposal Provided a Perfect Solution

The CMI debates demonstrate why the issue resisted simple regulation. An outright ban could obstruct genuine trade disputes. Unrestricted acceptance could encourage false clean Bills of Lading (B/Ls). Notification depended on effective disclosure. Bank guarantees shifted risk but added cost and complexity. Supplemental indemnities depended on banking acceptance and credible financial backing.

Each proposal protected some participants better than others, and none completely resolved the tension between documentary certainty and commercial necessity.

The Strongest Principle Was the Distinction Between Honesty and Deception

Across the early Belgian and French decisions, the Amsterdam debates, the Brighton sub-committee, the Madrid proposals, the Hamburg Rules, and Brown Jenkinson, one principle emerges consistently.

A Letter of Indemnity (LOI) used to manage a genuine commercial uncertainty is fundamentally different from an indemnity used to procure a knowingly false Bill of Lading (B/L).

The law can recognise contractual allocation of risk. It is far less willing to enforce an arrangement whose purpose is to deceive a buyer, bank, consignee, or other party relying on the transport document.

Continuing Importance of the International LOI Debate

The historical international debate remains relevant because modern shipping still depends on the credibility of Bills of Lading (B/Ls) while using Letters of Indemnity (LOIs) to solve practical problems.

Today's commercial environment is faster and more complex than the one considered by delegates in 1927 and 1955, but the allocation of interests remains recognisable. Sellers need documents that permit payment. Buyers and banks need reliable representations. Carriers need protection from claims. Insurers need accurate facts. Receivers need cargo without unnecessary delay.

The CMI discussions demonstrate that no indemnity should be evaluated only from the perspective of the two parties signing it. Its effect on the entire documentary chain must be considered.

For clean Bills of Lading (B/Ls), the safest dividing line remains the one developed through decades of maritime law: a bona fide disagreement may justify carefully structured protection, but a Letter of Indemnity (LOI) should not be treated as a lawful mechanism for concealing facts that make a clean Bill of Lading (B/L) knowingly false.

Brown Jenkinson ultimately gave English law a clear expression of that principle, while the earlier CMI work explains why the issue became so important to international shipping, banking, insurance, and trade.
