Contract Law

Brief Summary

Contract — Common mistake — The appellants entered into a contract to purchase shares in a company, believing it to be viable based on a balance sheet prepared during due diligence. The respondents, unaware of the company's true financial state, did not provide warranties beyond the audited financial statements. The appellants claimed a common mistake regarding the viability of the business vitiated the contract. The court held that the common mistake did not render the contract void as the parties did not agree that the contract's validity was conditional upon the existence of the assumed fact, and the appellants bore the risk of the assumption proving false.

Comprehensive Summary

Summary of Judgment


1. Introduction


This was an appeal to the Supreme Court of Appeal concerning the alleged invalidity of a written sale agreement on the basis of a failed common assumption (sometimes framed as a common mistake) relating to an existing or past fact. The appellant was Van Reenen Steel (Pty) Ltd (together with another purchaser, Hulton, referred to in the judgment as the second appellant). The respondents were Errol John Barnes Smith NO (the executor in the deceased estate of Rowley) and Richard Rosso (a minority shareholder).


The dispute arose after the purchasers acquired shares and loan account claims in Mortech Industries (Pty) Ltd from the sellers (Smith NO representing the estate, and Rosso). After the transaction, the purchasers contended that the parties had contracted on a shared but incorrect factual premise concerning the company’s viability and the accuracy/existence of assets and liabilities as reflected in a March 1998 balance sheet prepared during due diligence.


In the court a quo (Magid J), the purchasers’ challenge failed. The court below granted a declaratory order that the agreement remained of full force and effect, relying in particular on the Full Court statement in Wilson Bayly Holmes (Pty) Ltd v Maeyane and Others 1995 (4) SA 340 (W) that a common mistake about a state of affairs will not void a contract unless the parties agreed (expressly or tacitly) that the contract’s validity was conditional upon that state of affairs existing. The appeal was directed against that conclusion.


2. Material Facts


Rowley (deceased) had been the majority shareholder in Mortech Industries (Pty) Ltd. After Rowley’s death, Smith, as executor, held the estate’s interest. Rosso and Hulton each held smaller shareholdings. Hulton was the managing director (apparently since Rowley’s death), while Rosso played no significant operational role. Smith was not closely acquainted with the business’s operational details but knew that the company was in serious financial difficulty, including a called-up overdraft of approximately R3 million and the effective worthlessness of a R0.5 million claim against a failed creditor.


Smith was not willing to inject further capital. His practical options were to liquidate the company or sell the estate’s interest. Hulton believed that an injection of capital could make the company viable and introduced Van Reenen (managing director of Van Reenen Steel) as a potential investor/purchaser. Van Reenen conducted a due diligence investigation.


A handwritten balance sheet dated 31 March 1998 was produced, ostensibly prepared by Van Reenen during due diligence. The court accepted that this balance sheet was discussed with Smith during negotiations. However, it was significant (and treated as material by the court) that there was no allegation that Smith or Rosso made representations to the purchasers regarding the correctness of the items in that handwritten balance sheet. The sellers were not prepared to provide warranties or indemnities beyond those contained in the 1997 audited financial statements.


The written agreement was extensive (55 pages), with substantial provisions on warranties and indemnities. Clause 13 was central. It recorded that the sellers bound themselves only to the warranties and indemnities contained in the agreement and Schedule 5; that the purchasers entered into the agreement in reliance on the warranties, indemnities, and representations given “in terms of this Agreement”; and that, save for those recorded warranties, no representations or warranties of any nature (express or implied, oral or written) had been made or given by the sellers relating to the company or its business.


It was also common cause (as treated by the SCA) that the written contract expressed the parties’ consensus. The purchasers’ complaint was framed not as misrepresentation nor as a unilateral mistake induced by the sellers, but as a shared mistaken assumption that what was being sold was a viable business with assets and liabilities accurately reflected (and extant) as per the March 1998 balance sheet.


3. Legal Issues


The central legal question was whether a contract is vitiated where both parties share a common assumption relating to an existing or past fact, which assumption later proves false, in circumstances where the parties did not agree (expressly or tacitly) that the correctness of the assumption was a term or condition of the contract.


A related issue was whether the purchasers could avoid the agreement by characterising the mistake as something other than a mere mistaken motive, including reliance on the notion of error in substantia, or by invoking Dickinson Motors (Pty) Ltd v Oberholzer 1952 (1) SA 443 (A) as authority for a broader doctrine.


The dispute primarily concerned a question of law (the legal effect of a failed common assumption/common mistake on contractual validity), applied to largely accepted facts about the nature of the agreement, its warranty structure, and the absence of pleaded representations. The matter also involved an evaluative element in determining risk allocation and whether the alleged assumption could be treated as having been incorporated into the contract as an implied condition.


4. Court’s Reasoning


The SCA approached the matter by distinguishing different kinds of “assumptions” and their effects in contract. It emphasised that assumptions about a future state of affairs, if they operate on the agreement’s efficacy, are usually indistinguishable from conditions (often resolutive conditions, sometimes conditions precedent or ordinary terms). Referring to such matters as “assumptions” rather than conditions was said not to promote clarity.


The court then addressed assumptions relating to present or past facts. A unilateral mistake, on orthodox principles, does not by itself render a contract void unless it is legally operative in the sense discussed in Sonap Petroleum (SA) (Pty) Ltd (formerly known as Sonarep (SA) (Pty) Ltd) v Pappadogianis [1992] ZASCA 56; 1992 (3) SA 234 (A), including that the other party caused or is otherwise legally implicated in the mistake. The purchasers could not rely on unilateral mistake because the respondents were not alleged to have caused the error in the relevant sense.


Because the written contract was accepted to reflect the parties’ consensus and because the agreement confined reliance to the warranties and representations contained in the contract, the SCA treated reliance on the March 1998 statement as being excluded by the parties’ “ultimate agreement”. This supported the conclusion that, if the purchasers’ case depended on the March 1998 balance sheet’s correctness, that correctness had not been contractually secured by appropriate warranties or conditions.


The SCA then characterised a common assumption about an existing fact, where not elevated to a contractual term, as ordinarily amounting to no more than the reasons for contracting—in other words, a common motive (described as dwaling in beweegrede). The court stated that a contract cannot be avoided merely because a party’s (even shared) motive was mistaken, unless the contract was made dependent on that motive, or unless the elements of misrepresentation are present. In support, the court relied on the principle stated in African Realty Trust Ltd v Holmes 1922 AD 389, namely that courts are not concerned with the parties’ motives except insofar as they were expressly made part of the contract or are part of it by clear implication.


The SCA accepted that a failed common assumption can affect contractual validity where the contract expressly or impliedly contains a term making the assumption a condition of the contract’s efficacy, drawing support from Bell v Lever Bros Ltd [1931] UKHL 2; [1932] AC 161 (HL) and from the approach approved in Fourie v CDMO Homes (Pty) Ltd 1982 (1) SA 21 (A). It also referred to McRae and Another v Commonwealth Disposals Commission and Others (1951) 84 CLR 337 for the proposition that the inquiry is fundamentally one of construction: what did the promisor undertake—performance in all events, or only subject to the existence (original or continued) of a contemplated subject matter. This framed the key inquiry as whether, on the language and surrounding circumstances, the assumption was incorporated into the contract as a condition.


Applying these principles, the SCA held that the statement relied upon by the court below from Wilson Bayly Holmes (Pty) Ltd v Maeyane and Others 1995 (4) SA 340 (W) conformed to authority and principle. The purchasers’ alleged assumption (that a viable business with assets as per the March 1998 balance sheet was being sold) was not shown to have been made a contractual condition. On the contrary, the contractual architecture (especially clause 13) signalled that the purchasers relied on the warranties contained in the agreement and that the sellers gave no further warranties or representations beyond them.


The court further tested the correctness of the approach by considering the parties’ respective positions regarding the contested assumption. It reasoned that even if the purchasers would probably not have contracted had they known the true facts, there was no reason to believe the sellers would not have sold on the same terms even if they had known the business was not viable; viability was not shown to have been causally significant to their decision to sell. The SCA adopted the analytical lens described (with attribution) as focusing on risk allocation: determining which party assumed responsibility for the assumed facts being true, and therefore which party took the risk of those facts turning out otherwise. On the court’s assessment, the purchasers assumed that risk, particularly because Hulton knew the business, Van Reenen conducted due diligence, and the purchasers accepted warranties tied to the 1997 audited statements without insisting on warranties tied to the March 1998 balance sheet.


The purchasers’ reliance on Dickinson Motors (Pty) Ltd v Oberholzer 1952 (1) SA 443 (A) was rejected. The SCA construed Dickinson Motors as a case where the validity of the underlying agreement was not in issue; rather, the dispute concerned the nature/construction of the transaction and, in the context of the condictio indebiti, whether payment was made indebite. Schreiner JA’s reference to an agreement founded on a common mistake “impliedly treated as a condition” was read as consistent with the requirement that the assumption must be reflected at least as an implied condition to affect contractual efficacy. The SCA also noted that attempting to parse judicial language as though it were a statute was inappropriate, and that the quotation from Huddersfield Banking Company Limited v Henry Lister & Son Limited 1895 (2) Ch 273 in any event reinforced the condition-based approach.


Finally, the SCA addressed reliance on a supposed doctrine of error in substantia. Referring to academic commentary cited in the judgment and to Papadopoulos v Trans-State Properties and Investments Ltd 1979 (1) SA 682 (W), the court stated there was no need for such a doctrine in South African law and that courts had not vitiated contracts on that basis. It treated the notion as unhelpful: if the error excludes consensus, it is operative; if it does not, it is inoperative—so the label “error in substantia” merely reformulates rather than resolves the central inquiry.


On this reasoning, the SCA concluded that Magid J was correct to declare that the agreement remained in force.


5. Outcome and Relief


The Supreme Court of Appeal dismissed the appeal and upheld the declaratory order that the agreement between the parties was of full force and effect.


The appeal was dismissed with costs.

Held


The court held that a false common assumption relating to an existing or past fact does not render a contract void merely because it was shared by both parties. For such a mistake/assumption to vitiate the contract, the correctness of the assumption must have been incorporated into the contract as a term or condition (express or implied), or the requirements for another recognised vitiating factor (such as misrepresentation) must be satisfied.


On the facts, the alleged assumptions about Mortech’s viability and the March 1998 balance sheet were not made contractual conditions; the written agreement confined warranties and representations to those recorded (notably linked to the 1997 audited statements) and disavowed any other warranties or representations. The purchasers, having undertaken due diligence and contracted without warranties based on the March 1998 statement, bore the risk that their assumptions might be incorrect. The agreement therefore remained valid and enforceable, and the appeal failed with costs.


LEGAL PRINCIPLES


A common mistake/shared assumption about an existing or past fact does not, without more, void a contract where consensus exists; such an assumption will generally amount to a common motive (dwaling in beweegrede) unless incorporated into the contract.


Courts are not concerned with parties’ motives for contracting except insofar as those motives are made part of the contract expressly or by clear implication, in line with African Realty Trust Ltd v Holmes 1922 AD 389.


A contract may be avoided for common mistake only where the contract expressly or impliedly makes the truth of the assumed fact a condition of contractual efficacy, consistent with the approach discussed in Bell v Lever Bros Ltd [1931] UKHL 2; [1932] AC 161 (HL) and approved in South African authority such as Fourie v CDMO Homes (Pty) Ltd 1982 (1) SA 21 (A).


Determining whether a common assumption operates as a condition is fundamentally a matter of construction: what, on the language and surrounding circumstances, did the promisor undertake, and who assumed the risk of the assumption being false, as reflected in the reasoning drawn from McRae and Another v Commonwealth Disposals Commission and Others (1951) 84 CLR 337.


The concept of error in substantia is not required as an independent vitiating doctrine in South African contract law; the operative question remains whether the error prevents consensus (operative mistake) or not (inoperative mistake), as indicated in the judgment’s discussion (with reference to Papadopoulos v Trans-State Properties and Investments Ltd 1979 (1) SA 682 (W)).

JOHN BARNES SMITH NO First Respondent

Second Respondent

JJA and LEWIS AJA
Heard: 14 MARCH 2002

JUDGMENT
HARMS JA/
HARMS JA:
[1] The issue in this appeal is whether a contract
between the appellants on the one side and the respondents on the
other is vitiated
by the failure of a common assumption in relation
to an existing or past fact in the absence of an agreement which
elevated the correctness
of the assumption to a term or condition of
the contract. The Court below (Magid J) found against the appellants
by relying on a
statement of the Full Court in
Wilson Bayly Holmes
(Pty) Ltd v Maeyane and Others
1995 (4) SA 340
(W) 344I that –
‘
a common mistake relating to the existence of a
particular state of affairs will not render the contract void unless
it can be said
that the parties expressly or tacitly agreed that the
validity of the contract was conditional upon the existence of that
state of
affairs.’
[2] The first respondent (Smith) is the executor
in the deceased estate of one Rowley. Rowley was the majority
shareholder in Mortech
Industries (Pty) Ltd. The second respondent
(Rosso) and the second appellant (Hulton) each held a small number of
the remaining
shares. Hulton was, presumably since Rowley’s death,
the managing director and Rosso did not, it would appear, play any
significant
role in the affairs of the company. Smith was not
au
fait
with the details of the business but he was aware that the
company was in a dire financial position: the bank had called up an
overdraft
of R3m and a claim of R0.5m against a failed creditor was
worthless. He was not prepared to introduce further capital into the
business
and had either to liquidate the company or sell the estate’s
interest therein.
[3] Hulton, nevertheless, believed that an injection of capital would
make the company viable. He was able to attract the interest
of one
Van Reenen, the managing director of the first appellant (‘Van
Reenen Steel’), and after a ‘due diligence’ undertaken
by Van
Reenen, who holds a chartered accountancy degree but is a
businessman, Van Reenen Steel and Hulton purchased in an agreed
proportion from Smith and Rosso all their shares and claims to loan
accounts in the company.
[4] The appellants’ case is that it was –
‘
the common intention of the
parties that what was being bought and sold was a viable business,
the assets and liabilities of which
being known and disclosed by the
balance sheet [of 31 March 1998]’
and that consequently –
‘
all the parties to the agreement
laboured under the common and incorrect assumption of fact or common
mistake of fact that Mortech
had certain important attributes which
it did not have.’
Further –
‘
The mistake lay in the fundamental
assumptions of the value of the underlying assets being purchased,
the assumption that what was
being bought and sold was a viable
business as well as the assumption that the assets were known and
extant as disclosed by the balance
sheet [of 31 March 1998].’
[5] The 31 March 1998 balance sheet is a handwritten document,
ostensibly prepared by Van Reenen during his due diligence
investigation.
It has to be accepted that the balance sheet was
discussed with Smith during the negotiations preceding the conclusion
of the contract
but it should be noted that there is no allegation
that Smith, or for that matter Rosso, had made any representations to
the appellants
concerning the correctness of anything contained
therein. On the contrary, the sellers were not prepared to provide
any warranties
or indemnities beyond what was contained in the 1997
audited financial statements.
[6] The warranties and indemnities given or not given should be seen
in the context of a contract of fifty-five pages, twenty of
which
deal with warranties and indemnities. Of special significance is
clause 13:
‘
13.1 The Sellers bind themselves jointly and
severally to the Purchasers in accordance with the warranties and
indemnities given by
them in the attached Schedule 5.
13.2 The Sellers acknowledge that the Purchasers are
entering into this Agreement in reliance on the warranties,
indemnities and representations
given by the Sellers in terms of this
Agreement.
13.3 Each warranty and indemnity given by the Sellers in
terms of this Agreement shall be a separate warranty and shall in no
way
be limited or restricted by the provisions of any other warranty
or indemnity.
13.4 The Purchasers acknowledge and agree that, save for
the warranties set out in this Agreement and in the attached Schedule
5,
no representations or warranties of whatsoever nature, whether
express or implied, and whether oral or in writing, have been made
or
are given by the Sellers or by anyone else on behalf of the Sellers,
relating to the Company or to the affairs or business of
the
Company.’
[7] The first problem facing the appellants is
that they are unable to rely on a unilateral mistake because, as
mentioned, the respondents
were not the cause of the mistake in the
sense discussed in
Sonap Petroleum (SA) (Pty) Ltd (formerly known
as Sonarep (SA) (Pty) Ltd v Pappadogianis
[1992] ZASCA 56
;
1992 (3) SA 234
(A).
The next problem is that it is common cause that the written contract
expresses the parties’ consensus. Reliance on the
March statement
is not permitted by their ultimate agreement. It is for these
reasons that they take refuge in the ‘doctrine’
relating to
assumptions and that they argue that a false common assumption
relating to a present or past fact vitiates a contract
even if it is
not a term or condition of the contract.
[8] Assumptions or suppositions can have many forms and have
different effects depending upon the circumstances. An assumption
relating
to a future state of affairs –
‘
relates to an agreement which is
in operation and its recognition would have a direct bearing upon one
of the terms of the agreement.
Such a supposition is
indistinguishable from a condition,’
1
usually a resolutive condition, perhaps also a
condition precedent or an ordinary term of the contract.
2
The use of the word ‘supposition’ or ‘assumption’ instead of
‘condition’ in this context is not conducive to clear thinking.
[9] Assumptions may also relate to present or past
facts. If unilateral, one is back to the effect of a unilateral
mistake on a contract.
If common, unless elevated to terms of the
agreement, they invariably amount to no more than the reasons for
contracting (on those
terms)
3
or, expressing the same idea, common mistakes relating to a motive in
entering into the agreement (‘dwaling in beweegrede’).
4
Whether or not a motive leading up to an agreement is based upon an
assumption of fact, it remains a motive. A party cannot vitiate
a
contract based upon a mistaken motive relating to an existing fact,
even if the motive is common,
5
unless the contract is made dependent upon the motive, or if the
requirements for a misrepresentation are present.
6
The principle is as stated in
African Realty Trust Ltd v Holmes
1922 AD 389
403 –
‘
But as a Court, we are after all not concerned with
the motives which actuated the parties in entering into the contract,
except in
so far as they were expressly made part and parcel of the
contract or are part of the contract by clear implication.’
[10] In
Bell v Lever Bros Ltd
[1931] UKHL 2
;
[1932] AC 161
(HL), Lord Atkin
dealt likewise with common mistakes (although he referred to them as
mutual mistakes) and pointed out that there
is an alternative mode of
dealing with their effect (at 224)
‘
It is said that in such a case as the present there
is to be implied a stipulation in the contract that a condition of
its efficacy
is that the facts should be as understood by both
parties . . .’
and that (at 225) –
‘
if the contract expressly or impliedly contains a
term that a particular assumption is a condition of the contract, the
contract is
avoided if the assumption is not true.’
The latter statement accords with the views of De
Wet & Yeats
7
that were quoted with approval by this Court in
Fourie v
CDMO Homes (Pty) Ltd
1982 (1) SA 21
(A) 27 esp
in fine
.
[11]
In
McRae and Another v Commonwealth
Disposals Commission and Others
8
the Court in this context said that one must have regard to the basic
theory of contract and pose the fundamental question: ‘What
did the
promisor really promise?’ –
‘
Did he promise to perform his part
in all events, or only subject to the mutually contemplated original
or continued existence of
a particular subject matter? So questions
of intention or ‘presumed intention’ arise, and these must be
determined in the light
of the words used by the parties and
reasonable inferences from all the surrounding circumstances. That
the problem is fundamentally
one of construction is shown clearly by
Clifford v Watts
[(1870)
LR 5 CP 577].’
[12] Van der Merwe
et al
9
sum it all up:
‘
A
common mistake
is said to be present where
both parties to an agreement labour under the same incorrect
perception of a fact external to the minds
of the parties. Such a
mistake, of course, does not lead to dissensus: the parties are in
complete agreement, although their consensus
is based on an incorrect
assumption or supposition. This kind of mistake can be related to
the concept of a common underlying supposition
(’veronderstelling’)
on which the parties base their contract. In this manner the parties
can introduce a common motive into
the (terms of the) contract so
that a mistake in their common motive will render the contract
without further effect.’
[13] It follows from this that the quoted
statement in
Wilson Bayly Holmes
conforms to authority and
principle.
10
The correctness of the conclusion can be tested in other ways. If
the question were to be asked whether the appellants would not
have
concluded the agreement had they known of the true facts, the answer
is probably in the affirmative. There is, however, no
reason to
believe that the respondents, had they known the business was not
viable, would not have sold it on exactly the same terms
and
conditions. Whether the business was viable or not was to them of no
concern. The existence of the agreement was in their minds
not
subject to the correctness of their assumption. The viability of the
business was not causally connected to their decision to
sell, either
at all or on the agreed terms. PS Atiyah
11
suggests that the answer is to be found in determining which of the
parties assumed the responsibility for the truth of the assumed
facts, or, in other words, which of the parties has (or ought to be
treated as having) taken the risk of the facts turning out otherwise
than expected; only in the rare and unlikely event of neither party
having assumed this responsibility the falsity of the assumption
will
render the contract inoperative. There can be no doubt that it was
the appellants who took that risk especially since Hulton
knew the
business, Van Reenen had conducted a due diligence and they were
satisfied with a warranty based upon the 1997 audited statements
and
did not insist on one based upon the March 1998 statement.
[14] But, say the appellants, all of this is in
conflict with the judgment in
Dickinson Motors (Pty) Ltd v
Oberholzer
1952 (1) SA 443
(A) 450. A similar argument was
rejected in
Wilson Bayly Holmes
. The facts in
Dickenson
were these: the plaintiff claimed with the
condictio indebiti
repayment of an amount paid in error to the defendant. The substance
of the plaintiff's case was that he had paid the amount in
error
because both he and the defendant thought that the car which was to
be delivered to him in return for the payment was a Plymouth
motorcar
A, which had been sold to A G Oberholzer (plaintiff’s son) by the
defendant and had no idea that it was Plymouth B, which
belonged to
Alris Motors. The defendant then delivered Plymouth B to the
plaintiff and thereafter Alris Motors repossessed it.
‘
That there was this error common to both the parties
was not in dispute and the real issues in the case were what was the
nature of
the transaction which led to the payment and what legal
consequences flowed therefrom.’
(Per Schreiner JA at 448D.) The common error
referred to was the fact that the car delivered was car A and not car
B. It follows
from this quotation that the validity of the contract
was not in issue, only the nature of the contract. There was
consensus about
the vehicle involved and the amount payable. The
court was divided on the question of whether the contract was one of
sale or not.
Schreiner JA (Fagan JA concurring) held that it was and
that because of the fact that the issues in the case were fully
explored
it was unnecessary to decide the matter with reference to
the
condictio indebiti
. Since the plaintiff was lawfully
evicted and the defendant had failed to give him quiet possession,
the plaintiff was in any event
entitled to repayment of the money (at
449D-H.) Van den Heever JA did not agree that the agreement was one
of sale (at 451G) and
found that it was an agreement to release car A
by payment of the son’s debt.
[15] In dealing with this construction of the agreement Schreiner JA
made the statement upon which the appellants so heavily rely
(at
450A-F):
‘
But if the transaction be regarded
not as a fresh sale by the defendant to the plaintiff but as a
release of the car by the payment
of what was owing by A. G.
Oberholzer to the defendant the result is the same. For once it is
clear, as it undoubtedly is, that the
plaintiff, to the defendant's
knowledge, was only interested in obtaining the car and not in paying
his son's debts except as a means
of obtaining the car, the identity
of the car at Vereeniging as the one that A. G. Oberholzer had bought
from the defendant was of
vital importance. The plaintiff would not,
and the defendant knew that he would not, have considered paying his
son's indebtedness
except to secure the release of the car on which
the money was owing. It was only because the defendant's officers
believed that
the car at Vereeniging was the one they had sold to A.
G. Oberholzer that they were prepared to release it to his father
against
payment of his indebtedness. The £291 was paid under a
common mistake in regard to a matter which was vital to the
transaction
and if either of them had been aware of the true position
the transaction would not have gone through. In
Huddersfield
Banking Company Ltd v Henry Lister & Son Ltd.
,
1895 (2) Ch.
273
, LINDLEY, L.J., states the proposition,
“
that an agreement founded upon a common mistake,
which mistake is impliedly treated as a condition
12
which must exist in order to bring the agreement into operation, can
be set aside, formally if necessary, or treated as set aside
and as
invalid without any process or proceedings to do so.”
This seems to me to express in clear language a
principle which is inherent in all developed systems of law. No
question arises here
of neglect on the plaintiff's part giving rise
to the mistake; if blameworthiness were in issue the defendant, in
whose possession
the car was and who had the means of identifying it,
was the more to blame. Assuming that so long as the plaintiff
remained in possession
of Plymouth B he could not have recovered the
£291, once this was duly taken from him he was entitled to
recover from the defendant
what he had owing to a reasonable and
common error paid for it. It follows that on this alternative view
of the transaction, also,
the appeal could not succeed.’
[16] Once again, the existence of the release
agreement was not in issue. The parties were in agreement as to what
was to be released.
The reference to a reasonable and common error
relates to the payment of the money and not to the underlying
transaction. The payment
was for the release of car A; by delivering
car B, car A was not released; the payment was consequently
indebite
.
Counsel attempted to analyse the judgment as if it were a statute.
It is not. In any event, the quotation from
Huddersfield Banking
(a case that dealt with past or present facts) disposes conclusively
of the argument because it postulates that for a failed common
assumption to vitiate a contract it must at least be reflected in an
implied condition. It makes no difference if one were to call
the
mistake an incorrect assumption.
[17] The appellants finally relied upon the
‘doctrine’ of
error in substantia
. As Van der Merwe
et
al
(at 18) point out, there is no need for such a doctrine in our
law and our courts have yet to vitiate a contract on that ground.
13
If the
error in substantia
excludes consensus, it is
operative or material; if it does not do so, it is inoperative or
immaterial. In other words, by enquiring
whether the error is one
relating to substance, one is merely reformulating the primary
question and making it more difficult to
answer.
[18] Magid J was consequently correct in issuing a declaratory order
to the effect that the agreement between the parties is of full
force
and effect.
The appeal is dismissed with costs.

Banks v Cluver

458-459 accepted Von Savigny’s
classification. According to the latter an error in motive is one
that does not affect the will
of the contracting party but relates
to the preliminary process of the formation of the will. It is
contrasted with an error in
respect of the transaction. See R

In the reported
Huddersfield
judgment the word is
‘consideration’. I have checked the signed judgment in the
archives and Schreiner JA in fact used the
word ‘condition’.
Whether this was a slip of the pen or the correction of an obvious
mistake we do not know. The word ‘consideration’
–
considering its technical meaning in English law – appears to make
no sense in this context.
