III. Where There is no Express Provision

 

It is submitted that the Scottish court was right to reject the agency rationale in Spiersbridge

1 2 .3 4

Property Developments Ltd v. M uir Construction Ltd}1There, it was contended that the bank

 

had paid the beneficiary as agent of the account party because the bank’s undertaking in that

 

case began with the words ‘On behalfof’ the account party. The court rejected that argument

 

and held that the words ‘on behalf of’ in this context meant no more than ‘at the request of’

 

or ‘on the instructions of’.

 

B. Breach of contract

 

The account party’s entitlement to recover is sometimes explained on the basis of breach of

1 2 .3 5

contract by the beneficiary in demanding too much from the bank. Some commentators5758

 

have said that ‘[a]s the making ofan excessivedemand is, basically, a breach of the beneficiary’s

 

underlying contract’, the amount ought to be regarded as received in breach of that contract

 

and therefore the account party is entitled to recover it as damages for breach of contract. This

 

explanation is open to doubt both in terms of principle and as a matter of authority.

 

A demand for payment under a performance bond is not a demand made in breach of con­

1 2 .3 6

tract simply because the amount demanded (and received) is or turns out to be more than

 

the beneficiary’s actual loss. Whether a demand for payment under a bond is in breach of the

 

underlying contract depends on the terms of the underlying contract. But a demand for the

 

amount stated in the underlying contract and specified in the bond is not a demand in breach

 

of contract simply because the amount received turned out to be more than the beneficiary’s

 

actual loss. The underlying contract will normally not stipulate that the beneficiary is allowed

 

to demand no more than the amount of his actual loss, since in most cases the full extent of

 

the beneficiary’s loss will not be known at the time of a demand for payment. In the absence

 

of a provision in the underlying contract restricting the beneficiary’s demand to the amount of

 

his actual loss, it is difficult to see how a demand for the amount stipulated in the underlying

 

contract and reflected in the bond will be a breach of the underlying contract by reason only

 

that the beneficiary’s actual loss turned out to be less than the amount received. Since such a

 

demand is not a breach of the underlying contract, the theory of breach of contract cannot

 

explain the account party’s entitlement to any surplus in the hands of the beneficiary.

 

The breach of contract theory is not only insecure in principle, it lacks support in authority;

1 2 .3 7

there is no reported case which supports it. The Australian cases of Australasian Conference

 

Association Ltd v. Mainline Construction Pty Ltd (in liquidationf9601and Wood Hall Ltd v. The

 

Pipeline Authority™ are sometimes advanced as providing support for the breach of contract

 

analysis.6’ However, it is submitted that neither of these cases affords any support for that analysis. In the first, the Australasian Conference Association case, as has been indicated,62 the High Court ofAustralia decided unanimously that the issue as to which party (as between the issuer and the account party) was entitled to the surplus in the hands of the beneficiary had to be determined by reference to the underlying contract and it concluded, by a majority, that under the contract in that case it was the account party rather than the bank that was entitled to the surplus. In other words, the account party was entitled to the surplus because

Claims Against the Beneficiaryfo r Overpayments

that is what was provided for in the terms of the underlying contract not because the benefi­ ciary committed a breach of that contract by calling on the bond and receiving an amount which exceeded his actual loss.

12.38There was no suggestion that the beneficiary committed a breach of the underlying contract in demanding the full amount of the guarantee. On the contrary, after examining the relevant provisions of the underlying contract, Gibbs A.C.J. concluded that ‘[t]he combined effect of these provisions was that the [beneficiary] was entitled to call on the [issuer] to honour its undertaking to pay the money’.6364Nowhere in the judgment is there any suggestion that the account party’s entitlement to the surplus was based on the beneficiary’s breach of the under­ lying contract in making the demand for the stipulated amount which later turned out to exceed the amount of his actual loss.

12.39That the rationale of the decision in the.Australasian Conference case is that the account party was entitled to the surplus not because the demand of the beneficiary was in breach of con­ tract but because the underlying contract indicated that that was the intention of the parties is further supported by the statement ofGibbs J. in the subsequent case of WoodHallLtd v. The PipelineAuthority.™ There, Gibbs J., with whose judgment Barwick C. J. and Mason J. agreed, explained that in the Australasian Conference case it ‘was held that since the guarantee was given for the purposes of a provision of the building contract it was right to conclude that the parties to the guarantee mutually contemplated and agreed that the moneys whenprovided by the bank would be dealt with as the building contract required’.65 In the Wood Hall case the underlying transaction was one for the construction of a pipeline. Bank guarantees and reten­ tion guarantees were provided as substitutes for cash security and retention of moneys under conditions G4 and G24 respectively of the contract. When the work was almost complete the employer demanded payment from the bank under the guarantees. Tire account party commenced proceedings to restrain the bank from making payment to the employer on the ground that the employer was not entitled, under the terms of the underlying contract, to call on the guarantees. The High Court of Australia rejected the contention that the demand was made in breach of die underlying contract. It was held that the beneficiary was entitled to call on the bond but that once paid, the ‘money must be held as security for the [account party’s] due and faithful performance of the [underlying contract] ’.66 The decision in this case affords no support for the view that the account party’s right to recover any surplus is based on the idea that the beneficiary’s demand is in breach of the underlying contract because the amount demanded and received turned out to be more than the beneficiary’s loss.

C. Term implied into demand guarantee

12.40A further legal route that has been suggested for the account party’s claim is that of a term implied into the performance bond to the effect that the issuer shall recover the surplus on behalf of the account party. Even if such a term is implied into the performance bond it will only be effective to allow the issuer to recover the money from the beneficiary. For the account party to recover the money from the issuer, it may be necessary to imply another term into the contract between the issuer and the account party to the effect that if the account party

III. Where Utere is no Express Provision

has already reimbursed the issuer, any surplus recovered by the issuer will be held for the benefit of the account party. This view was advanced recently in the Scottish case of

Spiersbridge Properly Developments Ltd v. M uir Construction Ltd.67 A building contract required the contractor to procure a performance bond for the benefit of the employer. The employer demanded and received payment under the bond. The contractor claimed that it was obliged to and had reimbursed the bank pursuant to the terms of a counter-indemnity it gave the bank. The contractor also claimed that the grounds on which the employer (ben­ eficiary) called on the bond were erroneous and without foundation in that it, the contractor, was not in breach of contract as alleged. On this basis it contended that the employer was obliged to account to it for the sums received under the bond. There was a dispute between the parties as to whether the contractor was in breach of the building contract as alleged and, if so, as to the amount of any damages to which the employer was entitled. That dispute had not yet been determined. However, the parties were also in dispute as to whether, assuming the employer was ultimately found to be entitled to less than the amount it was paid under the

bond, it was obliged to account to the contractor for the surplus.

 

The employer accepted that it was not entitled to retain any such excess but contended that

1 2 .4 1

its duty to account was owed to the bank and not to the contractor. It was argued that the

 

bank’s entitlement to the surplus is based on a term implied into the performance bond to

 

the effect that where there is a surplus the beneficiary would repay it to the bank. To deal with

 

the contractor’s point that it had already reimbursed the bank, it was argued for the employer

 

that the implication of a term into the performance bond will be matched by a correspond­

 

ing term implied into the banking contract between the bank and the contractor under

 

which, if the bank had already been reimbursed by the contractor, the bank would repay the

 

surplus received from the beneficiary to the account party.

 

However, this contention was rejected because the two-stage process involving the implica­

1 2 .4 2

tion of terms into two separate contracts is unnecessarily complicated. As the court said, it

 

would give rise to difficult problems. For example, if the right to recover the overpayment

 

lies with the bank, how can the account party force the bank to sue effectively for it in a case

 

where the bank has already been reimbursed by the account party? There is also the practical

 

difficulty of the bank having to undertake the action at great expense to itself in respect of a

 

dispute about which it knows nothing and in the outcome of which it has no interest, since

 

it has the security of its counter-indemnity from the account party.

 

Secondly, the two-stage implied term route will present the court with a number of legal

1 2 .4 3

difficulties and could open up a wide scope for disputes and uncertainty. In the Spiersbridge

 

case the court identified some of the issues on which there will be uncertainty. These include the questions whether the bank is to be left on its own to sue, or whether it will be under the instructions of the account party as a kind ofdominus litis? What terms will be implied as regards expenses? Will the bank be held liable to the account party for its conduct of the litigation? Will the court imply into the banking contract reciprocal obligations on the account party to cooperate in the litigation, to provide documents and witnesses, to act diligently, etc.? How will claims to privilege and confidentiality be dealt with?678

Claims Against the Beneficiaryfo r Overpayments

12.44One may add that the complications involved in this two-stage process will only increase in an international transaction involving two banks, where it will become a three-stage process.

12.45Moreover, as already indicated,69 courts should be and are generally reluctant to imply terms into performance bonds since it is desirable that banks and other financial institutions deal­ ing with them should be able to determine the extent of the issuer’s liability on the face of the document. Therefore, just as the courts will not imply a term into the performance bond to enable the issuer to recover (for its own benefit) any excess from the beneficiary, so too they should be reluctant to imply a term into the performance bond to enable the issuer to recover on behalfof the account party.

D. Term implied into the underlying contract

12.46The legal route adopted by the English courts is that of a term implied into the underlying contract. In the absence of clear words to the contrary, a term is implied into the underlying contract to the effect that any surplus in the hands of the beneficiary will be repaid to the account party. This implied term route was first advanced by Morison J. in his very thoughtful judgment in Cargill International v. Bangladesh Sugar &Food Industries Corporation70 where he held that the ‘basis upon which recovery can be made in respect of an overpayment is, I think, contractual rather than quasi contractual. It seemjs] to me that it is necessary to imply into the contract that moneys paid under the bond which exceeded the [beneficiary’s] actual loss would be recoverable by the [account party]’.71723Morison J.’s decision was approved by the Court of Appeal in the CargillInternationalcase*1and also in Corndel Commodities Ltd v. Siporex Trade SA.13More recently, in Tradigrain v. State Trading Corporation ofIndia,74 Christopher Clarke J. concluded that the Cargill cast is authority for the proposition that there is an implied term (which we may refer to as the Cargill implied term) in the contract of sale that the buyer will account to the seller for any amount that has been paid under a performance bond to the extent that the amount paid exceeds the true amount of the buyer’s loss.

12.47When the term was first implied in the Cargillcase Morison J. said that it was implied either as a matter of necessity or on the basis that the implication of such a term was so obvious that its incorporation in the contract went without saying. However, today the Cargill implied term may be regarded as one implied by law75 since it is now a general rule of law that in all contracts (requiring one party to procure a performance bond for the benefit of the other) a Cargill- type term will be implied, unless the implication of such a term would be contrary to the clear words of the contract.76

12.48 It is submitted that the Cargill implied term route should be preferred (as opposed to the other suggested legal routes) because it avoids the practical and legal difficulties raised by the other legal routes advanced and it is consistent with the fundamental principle of

IV. Where There is no Contractual Relationship

independence of the performance bond obligation. Since the beneficiary is entitled to the performance bond in accordance with the terms of the underlying contract, it is right that the question whether or not he retains any overpayment under the bond should be deter­ mined by the same contract. Where the underlying contract contains an express term as to how any surplus is to be dealt with, effect is given to the term. It is not too much to say that

in the absence of an express term a term should be implied into the contract.

IV. W H ERE TH ERE IS NO CONTRACTUAL

RELATIONSHIP

Although the Cargill implied term is an appropriate legal response to the problem of over­ 1 2 .4 9 payments in most cases, it is incapable of providing a satisfactory answer in cases where there

is no contractual relationship between the beneficiary and the account party. Consider, for example, a case where the underlying contract for the sale of goods requires the performance bond to be issued for the benefit of a third party bank, as security for a financing facility provided by the bank to the buyer who has used it to make an advance payment to the seller. In such a case, there is no contractual relationship between the account party (the seller) and the beneficiary of the performance bond (the third party bank). Therefore, if there is any over­ payment to the beneficiary, the account party cannot recover it on the basis ofa Cargillimplied term. Consequently, unless the law can impose liability on the beneficiary on a different basis, he will retain the surplus as a windfall gain. This is hardly a result which can be viewed with much satisfaction. In the Tradigrain v. State Trading Corporation o fIndia,11for example, Christopher Clarke J. explained that a beneficiary who receives an overpayment must return it. ‘Otherwise they will retain a windfall in the form of money to which they were not entitled’.7879In view of the limitations of the Cargill implied term, can liability be imposed on the beneficiary on some other basis as a response to the windfall problem?

1. Term Implied into the Demand Guarantee?

A likely alternative source of a liability could be the terms (express or implied) of the perfor­

1 2 .5 0

mance bond. There should be no difficulty where the instrument contains a clear term stipu­

 

lating what is to happen to any surplus. But, as indicated above, in practice such an express

 

term is extremely rare. So, the question is whether, in a case where there is no contractual

 

relationship between the account party and the beneficiary, the court should imply a term

 

into the performance bond to the effect that the beneficiary is liable to account to the paying

 

bank (as opposed to the account party) for any surplus.

 

A. Uxinterimpex v. Standard Bank

 

In Uxinterimpex JSC v. Standard Bank Pic19 the courts answered that question firmly in the

1 2 .5 1

negative. The claimant, an Uzbek state cotton trading company (U), entered into a sale

Claims Against the Beneficiaryfo r Overpayments

contract with an English purchasing company (AMJ) concerning a series of consignments of cotton on FOB terms. The contract required AMJ to make advance payment to U in respect of 90 per cent of the value of the cotton, with the balance of the payment to be by letter of credit against documents of title. To make the advance payment, AMJ obtained a pre-export finance facility from a syndicate ofbanks for which the defendant bank (S) was the agent and issuing bank. In the ordinary way, the sale contract would have required Us bank to issue a performance bond in favour of AMJ as security for U’s performance of the sale contract. However, since the advance payment was to be made using funds provided by the syndicate, the sale contract specifically called for a guarantee to be issued by U’s bank in favour ofAMJ s nominated bank. And, when issued, the advance payment guarantee (APG) took the form of a direct undertaking by U’s bank to S.

1 2 .5 2 The guarantee provided for the amount payable to be automatically reduced by the value of each consignment of cotton delivered to AMJ. Under a security deed AMJ assigned to S all its rights under the sale contract and in the cotton, although AMJ was free to deal with and sell the cotton in the ordinary course of its business. AMJ was also required to remit the entire proceeds of the sale of the cotton to a ‘Transaction Account’ at S from which it would be distributed to the members of the syndicate (including S itself) and to AMJ insofar as the sub-sale had made a profit.

1 2 .5 3 After some consignments of cotton were delivered by U, disputes arose between U and AMJ about U ’s performance of the contract. S made a demand on the guarantee and received the full amount then outstanding. However, at the time of the demand AMJ had succeeded, with the assistance of S, not only in obtaining control of some of the con­ signments of cotton in respect of which the demand had been made but had sold some to its own customers and the proceeds of sale had been paid into the Transaction Account at S. In other words, when S received full payment under the guarantee it effectively received the value of the goods twice; once in the form of the proceeds of sub-sale which had been remitted into the Transaction Account and once in the form of a recovery of the price under the guarantee. This situation had come about because the parties failed to operate the con­ tractual arrangements in the manner intended, which would have ensured that there was no overpayment. At an arbitration, in which AMJ admitted obtaining possession of some amounts of the disputed cotton, arbitrators found a balance in favour of U in the sum of about US$ 8 million. However, U was unable to recover the money from AMJ because it went into liquidation. U then obtained an assignment from its bank of the bank’s claims under the APG and commenced proceedings against S to recover the overpayment. U ’s primary claim based on fraud failed because the evidence fell far short of the standard necessary to establish fraud.

1 2 .5 4 An alternative claim was that itwas an implied term oftheAPG that in the event drat any demand under it was ultimately found to have exceeded the loss suffered by AMJ and/or S or was other­ wise found to have been excessive, S should repay to U the surplus. The surplus in this casewas said to be die extent to which S received both the proceeds ofthe APG and the proceeds of the cotton to which it related. It was contended that the term should be implied into the instrument in this case because it was given not for the benefit ofa party to the underlying contract (the buyer) but rather to its bank. It was said that such a term was to be implied by law or as necessary in order to give business efficacy to the contract or to reflect the obvious intentions of the parties. It was also argued that if the term were not implied the bank, S, would obtain

288

I V

Where There is no Contractual Relationship

 

a windfall. That contention was firmly rejected by the Court of Appeal on the basis of the

 

policy reasons explained above.80

 

In addition, it was held that apart from the policy reasons, in the circumstances of this

1 2 .5 5

particular case the term could not be implied on any one of the grounds on which terms

 

are normally implied into a contract. First, the argument that the term was to be implied by

 

law was held to be untenable since no such term was to be implied into every performance

 

bond. Secondly, it was not necessary to imply a term of this kind in order to give business

 

efficacy to the contract because the guarantee stood as an independent contract between the

 

issuer and the beneficiary and was capable of operating effectively without the need for such a

 

term. Thirdly, although the court recognized that a term could be implied into a contract in

 

order to give effect to the parties’ intentions as to the manner of performance, in this case the

 

alleged term could not be implied on this basis because the contractual terms were designed

 

to make sure that there could be no excessive demand under the guarantee. The excess received

 

by the beneficiary only came about because the parties departed from the agreed method of

 

performance. In other words, the existence of contractual arrangements designed to avoid an

 

overpayment made the argument for an implied term to repay such overpayment Very

 

difficult to sustain because a term of that kind is only necessary if the parties have failed to

 

comply in some way with their obligations under the contractual arrangements’.81

 

The logic of the independence principle is that in the circumstances of the Uxinterimpex case,

1 2 .5 6

since the beneficiary’s liability to repay any overpayment could not be found on the basis of

 

the Cargill implied term, it could not be imposed on the basis of a term implied into the

 

guarantee itself. But was not the beneficiary in that case unjustly enriched by receiving the

 

proceeds of the advance payment guarantee and also receiving the proceeds of the cotton

 

to which it related? This

is the problem of windfall gain. In the Uxinterimpex case the

 

Court of Appeal said82 that the answer to the ‘windfall’ argument is that the account party,

 

the seller, was entitled to maintain a claim for the surplus against the buyer (AMJ) on the

 

basis of the Cargill implied term, despite the fact that in that case that remedy was of no

 

practical value to the seller since AMJ was insolvent. It is, with respect, submitted that if the

 

Cargill implied term is an answer to the windfall argument, it is not a very satisfactory

 

answer because the result in the Uxinterimpex case was that the beneficiary was actually

 

allowed to retain the surplus, which was a windfall gain, and the account party, the seller, was

 

left without a practical remedy.

 

The problem can also arise in the context of a counter-guarantee. The issuer of a perfor­

1 2 .5 7

mance bond, who has obtained a counter-guarantee from the account party, is a beneficiary

 

under the counter-guarantee but he is not a party to the underlying contract between the account party and the beneficiary of the performance bond. If there is an overpayment under the counter-guarantee, the Cargill implied term will not be able to provide the basis for a claim by the account party. The question then arises whether the account party can recover the surplus on the basis of a term implied into the counter-guarantee (as opposed to the underlying contract).

Claims Against the Beneficiaryfo r Overpayments

B. Technical & Guarantee Co v. Patterson

12.58In Technical & General Guarantee Co Ltd v. Patterson,m Mr Lancelot Henderson Q.C., sitting as a DeputyJudge of the High Court, expressed the view that ifat the end of the day the beneficiary of a counter-indemnity has suffered no loss*84 then it would be necessary to imply into the counter-indemnity an obligation to repay the money received.85 In that case the underlying contract was a building contract. At the request of the contractor, a guarantee company issued a performance bond to the employer in return for a counter-indemnity given to the guarantee company by the contractor. By the counter-indemnity the contractor undertook to place the guarantee company on demand in cleared funds sufficient to cover any actual and contin­ gent liability arising out of the performance bond. In addition, the defendant, who was a director of the contractor company, gave the guarantee company a personal guarantee, by which he undertook to pay on first demand all moneys owing or payable by the contractor to the guarantee company. The contractor having gone into liquidation, the guarantee com­ pany demanded payment under the defendant’s personal guarantee at a time when the employer had not yet demanded payment under the performance bond. The question was whether the defendant was liable under the personal guarantee even though a demand had not yet been made under the performance bond issued by the guarantee company.

12.59One reason advanced for the view that the defendant’s liability had not yet arisen was that if he were to pay and it later turned out that no demand was made under the performance bond there would be no way of recovering die money paid, since there was no provision for refund under the guarantee. However, Lancelot Henderson Q.C. rejected that contention, holding that in such a case a term requiring a refund should be implied into the guarantee. In other words, in a situation where the Cargill implied term could not apply, the Deputy Judge was prepared to impose on the beneficiary a liability to repay by means of a term implied into the payment instrument in order to reverse the windfall gain which the beneficiary would other­ wise enjoy.

12.60However, it is not clear whether this view remains good law in light of the subsequent decision of the Court of Appeal in the Uxinterimpex case. But the fact that the Deputy Judge was moved to resort to a term implied into the guarantee is an indication of the sense of potential injustice that can result if the beneficiary is allowed to retain his windfall gain.

2.Restitution

12.61Another possible basis of liability is unjust enrichment. It may be argued that the account party has a right to repayment of the surplus by means of a claim in restitution to reverse the beneficiary’s unjust enrichment. The beneficiary may be said to be unjustly enriched at the expense of the account party who will normally be under a liability to reimburse the bank.86 This argument is fortified by the fact that, as indicated above, one policy reason for the ben­ eficiary’s liability under the Cargill implied term is to reverse the beneficiary’s windfall gain.

IV. Where There is no Contractual Relationship

 

However, the unjust enrichment route to liability is not without difficulty. As is well-known,

 

for a claim of unjust enrichment to succeed it is not enough for the claimant to show that the

 

defendant has been enriched (in this context there is no doubt that the beneficiary is enriched

 

by the amount of the surplus). The claimant must in addition show that the enrichment was

 

at the claimant’s expense and that the enrichment was unjust.87 In a claim to recover an

 

overpayment from the beneficiary it might be difficult for the account party to establish these

 

two additional requirements,

 

A. Is the payment at the account party’s expense?

 

Concerning the requirement that the enrichment is at the claimant’s expense, the general

1 2 .6 2

rule88 is that a benefit conferred by a third party rather than the claimant himself is not

 

considered to be a benefit received at the expense of the claimant.89 In the context ofa claim by

 

the account party, the benefit received by the defendant (the beneficiary) is a benefit conferred

 

by a third party, the bank that paid under the performance bond as a principal. O f course, the

 

position would be different if the paying bank is regarded as the account party’s agent when

 

making payment to the beneficiary.90 However, as explained above,91 the agency analysis is

 

difficult to support. If the paying bank does not pay as agent for the account party, it could be

 

argued that, in keeping with the general rule, the beneficiary’s enrichment is not at the account

 

party’s expense. If so, a claim by the account party based on unjust enrichment will fail.

 

A possible answer to this argument may be found in the decision in Khan v. Permeyer,92 In that

1 2 .6 3

case, В paid money to C in the mistaken belief that he was discharging As debt to C. A, also

 

acting in the mistaken belief that he had an outstanding debt to C, reimbursed B. Unbeknown

 

to the parties the debt had already been discharged by a voluntary arrangement. It was held

 

by the Court of Appeal that A could maintain a restitutionary claim against C based on C ’s

 

unjust enrichment. Morritt L.J. said that a ‘payment by a third party under a mistaken belief which gives rise to unjust enrichment of the defendant may be recoverable by the person at whose ultimate expense it was paid if that person is also acting under the same mistake as the third party’.93 Applied to the context of the account party’s claim, this means that a payment by a third party, the bank, which results in unjust enrichment by the beneficiary (the amount of the overpayment) may be recoverable by the account party if it was paid at the ultimate expense of the account party. This may be the case where, as in Khan, the claimant has already reimbursed the third party who made the payment. It may therefore apply to the account party who has already reimbursed the paying bank. However, if this is so, it means that the account party may be able to bring a claim in restitution for unjust enrichment only in cases where the account party has already reimbursed the bank. Restitution for unjust enrichment will not be available in cases where the account party has not yet reimbursed the bank.94

90In such a case, the payment will be considered to be at the account party’s expense so that he can maintain a restitutionary claim against the beneficiary. See, e.g. Stevenson v. Mortimer (1778) 2 Cowp. 805; Holt v. Ely

Claims Against the Beneficiaryfo r Overpayments

B. Is the beneficiary’s enrichment unjust?

12.64 Moreover, even if the approach in Khan extends to the account party’s claim where he has not yet reimbursed the bank, there is still a difficulty with the other requirement for an unjust enrichment claim, namely that the enrichment must be unjust. The question of what is ‘unjust’ depends not on the idiosyncratic idea of what a particular judge considers to be unfair but rather on what is legally unjust as demonstrated by the authorities.95 Recognized unjust factors include:96 mistake, duress, undue influence, unconscionable dealing, and failure of consideration. In Khan, the payment was unjust because it was made under mistake and the claimant, acting under the same mistake, reimbursed the payer. In the case of the account party’s claim it is difficult to identify the possible unjust factor. The payment by the issuer (the bank) is not made under a mistake. It is made in accordance with the bank’s obligation under the instrument.97 The account party who reimburses the bank does not do so under a mistake. He does so, in the ordinary case, in accordance with his obligations under his counter-guarantee or indemnity to the bank. There is also no duress, undue influence, unconscionable dealing, necessity, failure of consideration, or any other recognized unjust factor.

12.65It is true that the categories of unjust factors are not closed98 and new unjust factors could be recognized in the future through the usual incremental development of the common law. And it may be that if English law of unjust enrichment decides to abandon its attachment to unjust factors and adopt the civilian model of a condictio indebiti (a claim for the recovery of money on the ground that it was not due)9910it will be possible for the beneficiary’s liability to repay any overpayment to be based on unjust enrichment. But, as the authorities now stand, a claim based on unjust enrichment requires an unjust factor and it is difficult to see the unjust factor on which the account party’s claim could be based.

12.66The same is true of a claim by the issuer instead of the account party. In the recent case of

Sucden FinancialLtd v. Fluxo-cane Oversears L td'00an individual, Mr Garcia, issued a perfor­ mance bond to secure the liability of his own companies to sugar brokers. There was a clause in the bond to the effect that a notice of default given by the brokers shall be conclusive evi­ dence of Mr Garcia’s liability under the bond. When a dispute arose between the company and the sugar brokers, the brokers made a demand for payment under the bond. Beatson J. held that Mr Garcia was liable to pay. In his application for permission to appeal he argued, inter alia, that if the demand was wrong he would have no remedy, since the only indemnity

97And the instrument itselfwould have been issued pursuant to the account party’sobligation under the under­ lying commercial contract. Thus, in Lane-Mtdlins v. Warrenby Pty Ltd [2004] NSWSC 817 at [56], Nicholas J. rejected an argument based on unjust enrichment saying that a payment validly made to a beneficiary under a demand guarantee cannot be said to be a benefit ‘unjustly received. No question of unjust enrichment can arise where the [beneficiaries] are paid the moneys which the Plaintiffarranged to be provided to them unconditionally.’

98See, e.g. CTN Cash and Carry Ltd v. Gallaher Ltd [1994] 4 All ER714, 720, per Sir Donald Nicholls V-C.

99In Deutsche Morgan Grenfell Group Pic v. IRC [2007] 1 AC 558 at [358], Lord Walker expressed a ‘tenta­ tive inclination to welcome any tendency of the English law of unjust enrichment to align itselfwith the civilian model. However, if the civilian model is adopted in the form of the pyramid suggested by Professor Birks, Unjust Enrichment (2nd edn, OUP, 2005) 116, then it will not do away with the need for careful analysis of particular unjust factors at the base of the pyramid.
