HARMS DP (NUGENT AND BOSIELO JJA concurring)
INTRODUCTION
[1] The plaintiffs (the present respondents) are the joint liquidators of Agrichicks
(Pty) Ltd (in liquidation). The defendant, Mr F J Smith, farms in the Zeerust district.
Initially, the plaintiffs sued Mr Smith for goods sold and delivered but later amended
their summons and filed a declaration claiming payment of R469 604.96 allegedly due
in terms of a written innominate agreement between Mr Smith and the company. The
declaration quoted the terms of the agreement extensively and concluded by alleging
that the company had performed all its obligations in terms of the agreement and that
the said amount was owing ‘in respect of day old chickens, poultry feed, medication and
vaccination delivered’ to Mr Smith under the agreement. Mr Smith admitted the
agreement but denied liability based on breaches by the company. In essence his plea
raised the exceptio non adimpleti contractus. He, in addition, instituted a counterclaim

for damages, alleging that the company had breached the contract in a number of
respects.
[2] The trial court (Landman J) upheld the claim in part and granted judgment
against Mr Smith for R242 628. The counterclaim was upheld to the extent of an award
of damages in the sum of R317 366.50. Both parties appealed to the Full Court of the
North West High Court, Mafikeng, comprising of Hendricks J and Kgoele and Moloto
AJJ. The plaintiffs’ appeal was upheld and Mr Smith’s cross-appeal was dismissed. The
net effect of that judgment was that Mr Smith was ordered to pay the plaintiffs’ claim in
full and that his counterclaim was dismissed.  Mr Smith sought and obtained special
leave to appeal to this court.
THE CONTRACT
[3] I do not intend to quote the terms of the contract at any length but will set out its
general scheme. As Hendricks J pointed out, the contract was not a ‘simple’ contract of
purchase and sale but rather regulated the relationship between the company as
supplier of day-old chickens and feedstuff and Mr Smith, on the other hand, as contract
farmer-grower. The company had to supply Mr Smith with day-old chickens, with the
required poultry feed for the different stages of their short lives, and with medication and
vaccination as and when required. Mr Smith had to rear them until they reached the
marketable age at about 37 days.  The company, within 45 days after supply of the day-
old chickens, had to collect the live broilers, weigh and slaughter them and market them
as processed broilers (‘slaghoenders’).
[4] Ownership of the chickens, poultry feed, medication and vaccination did not pass
to Mr Smith but remained the property of the company. The goods were to be used
exclusively for rearing the company’s chickens and Mr Smith was not entitled to
purchase feedstuff from other sources or to dispose of chickens to third parties.
[5] An important aspect of the agreement is the fact that it operated in cycles. A
cycle commenced with the first day of delivery of a consignment of day-old chickens
and it ended with the delivery of the next batch – an agreed average period of 56 days.
However, as mentioned, the company had to collect the broilers for slaughter within 45

days after the inception of a cycle. The final date of collection within a cycle was
referred to as the date of completion of that particular crop. This meant that the chicken
houses were to be empty for about 11 days, presumably to prepare them for the next
batch.
[6] Each cycle had to be accounted for individually.  The company had to credit Mr
Smith’s account with the agreed ‘price’ per live kilogram of broilers collected for
slaughter and had to debit his account with the agreed ‘price’ of the day-old chickens,
feed, medication and vaccination. The accounting date was to be 30 days subsequent
to the date of completion of any particular crop, and any credit balance of that particular
crop had to be paid to Mr Smith on that date.
[7] Any debit balance, however, had to be carried forward as the opening balance of
the next cycle. Should the debit balance of any specific cycle be carried forward more
than two times as the opening balance of the following cycle, the amount of the debit
balance had to be paid by Mr Smith to the company.
[8] The agreement also made provision for the issue of certificates of indebtedness
by the company’s auditor who could certify the balance of payments between the
parties ‘for any specific cycle’ – it did not permit the issue of a certificate on any day
within a cycle or in respect of any other indebtedness.
THE CLAIM AND THE EXCEPTIO NON ADIMPLETI CONTRACTUS
[9] The commencement date of the contract, which was signed during February
1999, was 15 June 1999 and it was to continue for five years from this date. Mr Smith
required a signed contract to obtain financing from the Land Bank to build the necessary
infrastructure for rearing chickens. However, a few days after the commencement date,
on 2 July, the company was placed under judicial management and it remained under
such management until its liquidation on 14 August 2002.
[10] In view of the fact that the claim and counterclaim both relate to the last two
cycles it is necessary to consider them closer. The first of these was the May 2002
cycle. It commenced on 15 May and the broilers were slaughtered on 26 June. On the

accounting date a month later it transpired that Mr Smith had suffered a loss and his
account was debited with R87 154.49. This amount, in terms of the agreement, had to
be carried over to the next cycle as its opening balance.
[11] The second cycle (referred to as the August cycle) began on 12 July which
implied that the anticipated slaughter date was to be 22 August, a week after liquidation.
The company supplied chickens, feed and medication for this cycle for a total of either
R322 088.95 (or R321 576.95 on Mr Smith’s version). However, on about 9 August the
company became unable to deliver the required feed and medicines in terms of the
agreement. Mr Smith was informed accordingly. He was also told that the company was
abandoning the chickens and that he was free to destroy or dispose of them.
[12] To limit his losses he purchased broken maize – which does not qualify as a
balanced diet – and other feed when that became available. No one on behalf of the
company in liquidation took any steps to collect the broilers for slaughter on the
anticipated date, and between 25 and 30 August he disposed of the chickens to third
parties. Only on 18 September the provisional liquidators, cynically, sought to reclaim
possession of the chickens. The application was not successful.
[13] Mr Smith was taken to task during cross-examination at both the liquidation
inquiry and the trial in lawyerly language for having sold the chickens in spite of the
reservation of ownership. I fail to understand the problem. In the light of his uncontested
evidence the company abandoned its ownership and the chickens became res
derelictae. Mr Smith appropriated them and became owner by means of occupatio. See
Reck v Mills 1990 (1) SA 751 (A). In any event, it is not permissible to question
witnesses on legal issues – the more so if the cross-examiner’s knowledge of the law is
not up to scratch – and courts and chairpersons conducting inquiries should not permit
this type of debate.
[14] As mentioned, Mr Smith’s main defence is the exceptio non adimpleti contractus.
The principles of this defence are well established and a detailed restatement is not

required. As stated in the title ‘Contract’ in 5(1) Lawsa 2 ed para 210,1 in the case of
reciprocal contracts, one party undertakes to perform specifically in exchange for a
particular counter performance by the other. In such cases, the principle of reciprocity
applies: the first party is not entitled to demand counter performance from the other
party unless the first party has him or herself performed or is prepared to perform, as
the case may be.
[15] In Motor Racing Enterprises,2 the court laid stress on the following relevant
principles: First, the exceptio presupposes the existence of mutual obligations which are
intended to be performed reciprocally, and that the parties’ intention is to be sought
primarily in the terms of their agreement. Second, interdependent promises are prima
facie reciprocal. Third, the exceptio is often a temporary defence raised in order to
compel the other contracting party to perform unfulfilled obligation(s) but only if
defective performance of an obligatio faciendi can still be remedied. It is otherwise a
complete defence. Fourth, the applicability of the exceptio is (subject to the de minimis
principle) not dependent on the degree of non-performance.
[16] The plaintiffs’ declaration stated, as it had to, that the company had performed all
its obligations in terms of the contract and that the claimed amount represented the
debit balance on Mr Smith’s account with the company, which had been carried forward
for more than two cycles, as contemplated in the agreement. But it is here where the
plaintiffs’ case broke down. The amount of R87 154.49, which represented the loss
incurred in respect of the May cycle, was not carried forward for more than two cycles
due the company’s breach of contract and, accordingly, did not become payable. And
although it is fair to accept that the company supplied chickens, feed and medication for
the August cycle for some R322 088.95, the company failed to comply with its obligation
to supply the necessary feed etc for the full cycle and, instead, abandoned the chickens
and Mr Smith. As the plaintiffs themselves realized when they amended their summons,
the company did not ‘sell’ chickens and feed and the like in batches or at all. In spite of

reported as Motor Racing Enterprises (Pty) Ltd (In Liquidation) v NPS (Electronics) Ltd 1996 (4) SA 950
(A) per H J O van Heerden JA.

this the plaintiffs sought to rely on an auditor’s certificate which certified the alleged
balance on a date during the August cycle while, as mentioned, it could only certify the
balance of payments between the parties ‘for any specific cycle’.3
[17] Landman J, in the first instance, and the full court in the second instance,
although conscious of the nature of the contract and Mr Smith’s defence, did not deal
squarely with the issue. It would appear that sight was lost of the impact of their own
findings that that the agreement operated in cycles and was, within a cycle, not divisible,
and that the company had failed to comply with its obligations during the August cycle
and that the May debit had not become payable.
[18] Landman J referred to the fact that Mr Smith used the feed and this, too, appears
to have influenced the full court. Obviously, as was said in Motor Racing Enterprises in
connection with the fourth point mentioned above, a plaintiff who fails to prove full and
proper performance is not necessarily remediless. If a proper case is made out for such
relief, he may be entitled to claim a lesser amount than that provided for in the
agreement. However, unless the lesser amount is claimed, it is not for the court to
speculate what the amount should be. In claiming a lesser amount, it is necessary for
the plaintiff to allege and prove:4
(a)
that the employer has utilised his or her work to the employer’s own advantage
even though it fell short of the required contractual standards;
(b)
the cost of remedying defects and supplementing shortfalls;
(c)
that it would be equitable to award the contractor some remuneration even
though he or she breached the agreement;
(d)
that the circumstances as a whole are such that the court ought to exercise its
discretion in awarding the contractor a reduced contract price.

3 It is not necessary to deal with the other palpable defects in the certificate such at that it does not
purport to have been issued by the company’s auditor or that it merely stated what the company books
reflected and the effect of an alleged admission at the pre-trial conference. Furthermore, as Landman J
correctly found, the amount certified was even on the plaintiffs’ case patently incorrect.

The liquidators did not seek to avail themselves of this alternative and it need not be
considered. In any event, it is questionable that they would have succeeded in the light
of the facts of the case.
[19] It follows that the plaintiffs’ submission that it is immaterial that the company did
not comply with its contract after 9 August because Mr Smith’s indebtedness was for
payment in respect of chickens and goods actually supplied before that date is fatally
flawed. This means that the plaintiffs’ claim in convention should have been dismissed
at the outset and that both courts below have erred in granting judgment against Mr
Smith.
THE COUNTERCLAIM
[20] As mentioned, Mr Smith’s counterclaim, which was based on particular breaches
of contract, was upheld by Landman J but dismissed by the full court. The two
breaches, which were also used to ground the exceptio, will be dealt with briefly for
reasons that follow.
[21] The plaintiffs submitted that they suffered under a disability in conducting their
case because they could not reasonably be expected to have had direct knowledge of
events prior to the winding-up of the company and that, consequently, the dearth of
evidence on their side should not be held against them. The submission is without merit.
The company was at all relevant times under judicial management and there is no
indication that the judicial manager or the employees could not supply the necessary
evidence.
[22] Mr Smith relied on a tacit term of the contract which obliged the company to
deliver F1 day-old chickens. F1 crosses or hybrids are high quality because, in terms of
Mendel’s law, they tend to be uniform. Instead, he alleged, the company breached this
term by having provided poor quality day-old chickens instead of F1 chickens. In this
regard he was able to show that F1 chickens were used industry-wide for producing
broilers, that the company initially provided F1s, that as the company’s financial
difficulties increased it began supplying cheaper F2s, and that it instructed its
employees to hide the change from the farmer-growers. All this, as found by Landman

J, sufficed to establish the tacit term and it is not an answer to a reliance on a tacit
term to hold, as the full court did, that the written contract did not mention F1s but
‘chicken’ only. If the word in context cannot include bantam or ostrich chickens there is
little reason to hold that it cannot in context be limited to F1 chickens.
[23] The other ground on which Mr Smith relied was that that the company delivered
sub-standard chicken feed in contravention of the Fertilizers, Farm Feeds, Agricultural
Remedies and Stock Remedies Act 36 of 1947. There were two aspects to this part of
his case: it meant that having acted illegally the company was not entitled to recover the
contract price and also that the company had breached a tacit term that only standard
feedstuffs would be supplied. Landman J found in favour of Mr Smith but the full court,
relying on an interpretation of the Act, held otherwise. Although I prefer the approach of
Landman J, it is not necessary to decide the point for reasons that follow.
[24] I am prepared to assume for purposes of the judgment that the terms of the
contract and the breaches have been established and that Mr Smith is in principle
entitled to recover any losses suffered in consequence of the breaches. However, I am
not satisfied that Mr Smith has suffered any recoverable loss and will consequently limit
the judgment to that aspect.
[25] A certain Dr Viljoen was called by Mr Smith to quantify his loss. Landman J
accepted Dr Viljoen’s assumptions and calculations and held that the loss amounted to
R317 366.50 This was only R9.00 less than Dr Viljoen’s calculation. Because the full
court had found that the breaches were not established, its findings about quantum
were obiter and can be discounted.
[26] The counterclaim was limited to losses suffered during the May and August
cycles. During the May cycle Mr Smith received 85 889 day-old chickens and produced
and delivered 65 784 broilers to the company but, as mentioned, he suffered a loss of
R87 154,49 after deducting the cost of the chickens, feed etc. During the August cycle
he received 63 927 day-old chickens. We do not know the mortality rate or how many
were sold as broilers but one can fairly assume that not more than 60 000 would so
have been sold. One could also assume in Mr Smith’s favour that if the company had

complied with the relevant contractual obligations the mortality rate would have been
lower and that he would have been able to deliver some 80 000 chickens during the
May cycle. This means that one has to determine what Mr Smith’s reasonable margin of
profit on 140 000 broilers should have been.
[27] The evidence of Dr Viljoen was that a reasonable return per broiler would have
been between 70c and R1.00 each. He later sought to up the figure to R1.77 with
reference to the profit made during the relevant period by another farmer, Mr Harman,
who also produced broilers under contract with the company and, presumably, received
more or less the same type of day-old chickens and feedstuff. Although Mr Harman’s
results are prima facie destructive of Mr Smith’s case that the losses suffered were as a
result of the company’s breaches, I am prepared to assume in his favour that his return
would have been R1.00 per broiler, giving a total of R140 000.
[28] In assessing Mr Smith’s loss, if any, it is necessary to take into account any
benefits received from the company and his income from the sale of the abandoned
broilers to third parties. It will be recalled that Mr Smith did not pay the company
anything for the goods received during the August cycle. The only expenses which can
be taken into account for present purposes were the costs relating to the purchase of
feed after the company had reneged on its contract. These amounted to R58 595.00.
But with sales of R249 743.48 it means that Mr Smith made a profit of some R191
148.48, which is substantially more that the projected loss of R140 000.00. It would
have been different if he had paid or had to pay the company or the plaintiffs, in which
event his loss in respect of the August cycle would have been R130 428.47 plus the
assumed R80 000.00 loss in relation to the May cycle.
CONCLUSION
[29] This means that the correct order in the high court should have been a dismissal
of both the claim and the counterclaim. Since both were upheld the parties were justified
in appealing and the full court should have upheld both appeal and cross-appeal. The
appeal in this court has to succeed. Costs are to follow the different results.
[30] The following order issues:

1 The appeal is upheld with costs.
2 The order of the full court is set aside and replaced with an order in the following
terms:
a. The appeal of the liquidators is upheld with costs.
b. The cross-appeal of the defendant is upheld with costs.
c. The order of the trial court is amended to read: ‘Claim and counterclaim
are both dismissed with costs.’
