NUGENT JA (CLOETE, PONNAN, SNYDERS and BOSIELO JJA
concurring)

[1] The appellant (AB Ventures) sued the respondent (Siemens) in the
North Gauteng High Court for damages in delict. Siemens excepted to the
particulars of claim on the grounds that they lacked averments necessary
to found an action. The exception was upheld by Fabricius AJ and AB
Ventures now appeals with the leave of that court.

[2] An exception of this kind must be determined as if the allegations
of fact in the particulars of claim have been established. I do not intend
setting out those allegations in detail. It is sufficient for present purposes
for them to be summarized.

[3] AB Ventures concluded a written agreement with Lumwana
Mining Company Limited (Lumwana) under which AB Ventures
undertook to construct to completion the Lumwana Copper Mine in

northern Zambia. A joint venture between Ausenco Americas LLC and
Bateman International Projects BV was to supply four specialized
electrical units (referred to in the particulars of claim as ‘the drives’) that
were to be used by AB Ventures in the project. The joint venture
concluded a written agreement with Siemens under which Siemens
undertook to engineer, design, manufacture, supply and commission the
drives.

[4] Siemens delivered, installed and commissioned the drives at the
construction site. After the drives had been commissioned they
malfunctioned, resulting in a failure of the transformers in which the
drives were used. That caused the completion of the project to be delayed,
in consequence of which, AB Ventures alleged, it became liable to
Lumwana for penalties or damages under the construction contract, and it
also incurred additional expenses. AB Ventures alleged that the
malfunction of the drives and the resultant loss was caused by negligence
on the part of Siemens and it claimed damages to compensate for its loss.

[5] Although not elegantly expressed the issue that was presented by
the exception was whether the conduct of Siemens – which must be
accepted to have been negligent for present purposes – was wrongful and
thus actionable at the hands of AB Ventures. That is quintessentially a
matter that is capable of being decided on exception.1

[6] Liability for negligent conduct has been developed and continues
to develop incrementally as the expectations and needs of society evolve.
The law has for long recognised that physical loss caused by a positive

1 Telematrix (Pty) Ltd t/a Matrix Vehicle Tracking v Advertising Standards Authority SA 2006 (1) SA
461 (SCA) para 3.

act of negligence is actionable. It is now 32 years since this court in
Administrateur, Natal v Trust Bank van Afrika Bpk2 took a significant
step in the development of the law when it placed its imprimatur3 on the
recognition of a claim for recovery of damages for pure economic loss
caused by a misstatement that is made negligently.4 Since then the law
has been developed further to recognize that a bank may be liable to the
true owner of a cheque that it collects negligently,5 and to recognise
claims for pure economic loss in other diverse circumstances,6 and no
doubt the law will continue its development to include other
circumstances. This is one such case in which we are asked to take
another step in that direction.

[7] Various epithets have been used to express the nature of the
enquiry to be made when the law is sought to be developed in that way7 –
whether the ‘legal convictions of the community’ call for the recognition
of liability, whether the plaintiff’s interest falls within ‘the range of
interests that the law sees fit to protect against negligence’, the ‘boni
mores’ of society, the ‘general criterion of reasonableness’ – but in each
case the expression is so wide as not to be a true test at all. They
nonetheless help to direct attention to the nature of the enquiry.

7The same considerations apply when the law is developed to encompass new cases arising from
negligent omissions.

[8] Cases that have been decided in this court for thirty years and more
make it clear that the enquiry underlying those expressions is whether
contemporary social and legal policy calls for the law to be extended to
the exigencies of the particular case.8 Thus as early as Trust Bank Rumpff
JA said that when ‘legal duty’ (wrongfulness) is under consideration
‘policy considerations’ come into play.9 He likened it to the ‘duty
concept’ in the English tort of negligence, which Millner, Negligence in
Modern Law10, described as ‘a device of judicial control over the area of
actionable negligence on grounds of policy’. He went on to cite the
description by Fleming, The Law of Torts11 of the nature of that policy
enquiry:
‘In short, recognition of a duty of care [in the parlance of this country, whether the
conduct is wrongful] is the outcome of a value judgment, that the plaintiff’s invaded
interest is deemed worthy of legal protection against negligent interference by
conduct of the kind alleged against the defendant. In the decision whether or not there
is a duty, many factors interplay: the hand of history, our ideas of morals and justice,
the convenience of administering the rule and our social ideas of as to where the loss
should fall. Hence, the incidence and extent of duties are liable to adjustment in the
light of the constant shifts and changes in community attitudes.’

[9] For in each such case a court is being asked to extend the common
law, and all of the common law, from its beginnings, is the product of

contemporaneous social and legal policy. That was aptly captured by the
famous statement of Oliver Wendell Holmes Jr in the introduction to his
lectures on the common law – ‘the life of the common law has not been
logic: it has been experience’ – and from what followed:12
‘The felt necessities of the time, the prevalent moral and political theories, intuitions
of public policy, avowed or unconscious, even the prejudices which judges share with
their fellow-men, have had a good deal more to do than the syllogism in determining
the rules by which men should be governed. The law embodies the story of a nation’s
development through many centuries, and it cannot be dealt with as if it contained
only the axioms and corollaries of a book of mathematics. In order to know what it is,
we must know what it has been, and what it tends to become . . . The substance of the
law at any given time pretty nearly corresponds, so far as it goes, with what is then
understood to be convenient . . .’.

[10] Thus by the very nature of the enquiry it will generally not be
helpful in a particular case to look to what has been decided in other cases
of an altogether different kind. Where the case is not one that fits within
the social and legal policy that has led to liability being recognised in
other cases, then what is called for instead is reflection upon what
considerations there might be that necessitate the law also being advanced
to meet the new case. That calls not for a mere intuitive reaction to the
facts of the particular case but for the balancing of identifiable norms.13

[11] For in Telematrix (Pty) Ltd v Advertising Standards Authority SA
AB Ventures14 Harms JA reminded us that the first principle of the law of
delict is that loss ordinarily lies where it falls and that Aquilian liability
provides an exception to that rule. He went on to say that

14Above.

‘[w]hen dealing with the negligent causation of pure economic loss it is well to
remember that the act or omission is not prima facie wrongful . . . and that more is
needed. Policy considerations must dictate that the plaintiff should be entitled to be
recompensed by the defendant for the loss suffered . . .. In other words, conduct is
wrongful if public policy considerations demand that in the circumstances the plaintiff
has to be compensated for the loss caused by the negligent act or omission of the
defendant.’

[12] In this case counsel for AB Ventures placed heavy reliance upon
cases that fall under the rubric of what has come to be called ‘products’ or
‘manufacturer’s’ liability. It was submitted that, analogous to those cases,
Siemens held itself out as having special skill and knowledge relating to
the design and manufacture of units of the kind that are now in issue, and
is thus liable for loss caused to the user by a defect in the product. The
submission aligned itself with what was said in Ciba-Geigy (Pty) Ltd v
Lushof Farms (Pty) Ltd:15
‘[A] manufacturer who distributes a product commercially, which, in the course of its
intended use, and as the result of a defect, causes damage to the consumer thereof,
acts wrongfully and thus unlawfully . . .’..16

[13] The landmark case that commenced that form of liability in
England was the famous case of the snail in the bottle of ginger beer
(Donoghue v Stevenson17) and in the United States the case of the
defective motor vehicle (MacPherson v Buick Motor Co18). The
significance of those cases was that they loosened the contractual nexus
that until then had been required for liability. Professor Boberg19 has
pointed out that there has been no such landmark judgment in this country

in which the more flexible principles of our law have allowed for its
development to encompass those circumstances.20

[14] I do not find it necessary to deal with the cases of that kind that we
were referred to21 or to examine the elements of ‘products liability’
generally.22 Liability has been recognized in cases of that kind for reasons
that have no application in this case. Professor Boberg points out that
they are founded on the perceived need to protect consumers against the
risks to which they are exposed by the impersonal distribution of
consumer goods in modern society:
‘The manufacture and sale of goods that is the essence of an industrialized capitalist
economy is an activity potentially harmful to others. For the ultimate purchaser or a
third party may suffer damage to his person, property or purse through a product that
is defective or even through one that is not. He will demand legal redress, and the law
must determine under what conditions it should be given to him. In so doing the
individual’s interest will have to be weighed against the socio-economic utility of the
damage-producing activity, and the ensuing liability so fashioned that it affords
adequate protection without stifling beneficial industrial progress . . .. The growth of
mass-production and technology tends to increase consumer risk (identical products
suffer from identical defects) and to relegate the intermediate dealer to a position of
mere distributorship, focusing attention upon the manufacturer as the appropriate
defendant. His liability to those with whom he has not contracted can only be found in
delict.’23

20P 194.
21Amongst which were Cooper & Nephews v Visser 1920 AD 111, A Gibb & Son (Pty) Ltd v Taylor &
Mitchell Timber Supply Co (Pty) Ltd 1975 (2) SA 457 (W) and Ciba-Geigy (Pty) Ltd v Lushof Farms
(Pty) Ltd, above. In those cases the claim was for physical loss but a claim for pure economic loss was
allowed in Freddy Hirsch Group (Pty) Ltd v Chickenland (Pty) Ltd 2010 (1) 8 (GSJ). Subsequent to the
hearing of the appeal in this case judgment was handed down by this court on appeal against that
decision: Freddy Hirsch Group (Pty) Ltd v Chickenland (Pty) Ltd [2011] ZASCA 22. The quite
different facts of that case, and the basis upon which the claim was upheld, make it unhelpful to
deciding this case. Reliance was also placed on the decision of this court in Chartaprops 16 (Pty) Ltd &
another v Silberman 2009 (1) SA 265 (SCA). In that case the defendant was held vicariously liable for
the act of its servant and it has no application.
22J Neethling, JM Potgieter, PJ Visser Law of Delict 5ed ( translated and edited by JC Knobel), pp 291-
301.
23Pp 193-194.

To the same effect Professor Neethling et al24 say that the problem that
has given rise to products liability
‘is inherent in modern highly industrialised communities. Increasing industrialisation
and mechanisation have brought about a constant and daily potential of prejudice in
the form of the unavoidable risk which defective consumer products create for the
individual.’25

[15] The considerations of policy that underlie cases of products
liability have no bearing upon a case of the present kind. We are not
concerned in this case with anonymous consumers of mass-produced
goods. We are concerned with a major construction project involving a
multiplicity of contractors and sub-contractors whose co-operation was
defined through a web of inter-related contractual rights and obligations.
That bears no resemblance to the distant and impersonal relationship that
characterises the distribution of bottles of ginger beer and motor vehicles.

[16] It seems to me that there would be major implications for a multi-
partied project of this kind if each of the participants was to be bound not
only to adhere strictly to the terms of its specific contractual relationship
but, in addition, it was to be held bound to all the other participants by a
general regime of reasonableness. As pointed out in Lillicrap, Wassenaar
and Partners v Pilkington Brothers (SA) (Pty) Ltd,26 in a related context
that finds equal application in this case:
‘[In] general, contracting parties contemplate that their contract should lay down the
ambit of their reciprocal rights and obligations. To that end they would define,
expressly or tacitly, the nature and quality of the performance required from each
party. If the Aquilian action were generally available for defective performance of
contractual obligations, a party’s performance would presumably have to be tested not

24Law of Delict, above.

only against the definition of his duties in the contract, but also by applying the
standard of the bonus paterfamilias. How is the latter standard to be determined?
Could it conceivably be higher or lower than the contractual one?’
In this case in which Siemens bound itself to the joint venture to conform
to the standards specified in its contract, it would be most anomalous if it
was to be bound to a stranger to conform to a different standard.

[17] That points to why it is fallacious to align a case of this kind to
cases concerning products liability. In those cases it is not possible in any
practical sense for a consumer to protect himself or herself against harm
caused by the negligence of the manufacturer. But where an activity is
engaged in that is itself the product of a contractual arrangement then
generally the very contract that brought about the engagement will be
capable of regulating exposure to loss. That is the ground upon which the
claim failed in Pilkington Brothers and why it must similarly fail in this
case.

[18] Pilkington Brothers was also decided on exception. The facts
alleged were that Pilkington Brothers (the plaintiff) appointed Lillicrap,
Wassenaar and Partners (the defendant) as its consultant engineer to
investigate the suitability of a site for the construction of a glass
manufacturing plant. If the site was found to be suitable then the
defendant was to design and supervise construction of the plant. The
defendant advised the plaintiff that the site was suitable and it proceeded
to design the works. A formal agreement was then executed confirming
the appointment. (The rights and duties under the agreement were later
assigned to a third party but for present purposes I need deal only with
the position before that occurred.) The plaintiff alleged that the defendant
was negligent in failing to incorporate in its design sufficient safeguards

against soil movement and that it was negligent in its supervision of the
works and it claimed loss alleged to have been incurred through such
negligence. Its claim was brought in delict and an exception was taken to
the particulars of claim on the same grounds that the exception was taken
in this case – that the conduct complained of was not wrongful for
purposes of delictual liability.27

[19] Pointing out that our law ‘does not extend the scope of the
Aquilian action to new situations unless there are positive policy
considerations which favour such an extension,’28 Grosskopf AJA said
that the first question to be asked was whether there was a need for the
law to be extended to protect the plaintiff against negligence. He
concluded that there was no such need because the existing law enabled
the plaintiff to protect itself through the contract that it had concluded. He
reasoned as follows:
‘In my view, the answer [to the question whether an extension of Aquilian liability is
justified in the present case] must be in the negative, at any rate in so far as liability is
said to have arisen while there was a contractual nexus between the parties. While the
contract persisted, each party had adequate and satisfactory remedies if the other were
to have committed a breach . . .. When parties enter into such a contract, they
normally regulate those features which they consider important for the purpose of the
relationship which they are creating . . .. [I]n general, contracting parties contemplate
that their contract should lay down the ambit of their reciprocal rights and obligations.
To that end they would define, expressly or tacitly, the nature and quality of the
performance required from each party.’ 29
And later:
‘Apart from defining the parties’ respective duties (including the standard of
performance required) a contract may regulate other aspects of the relationship

27At 496I-497B. There were further grounds for the exception that are not relevant to this case.

29At 500F-I.

between the parties. Thus, for instance, it may limit or extend liability, impose
penalties or grant indemnities, provide special methods of settling disputes (eg by
arbitration) etc. A Court should therefore in my view be loath to extend the law of
delict into this area and thereby eliminate provisions which the parties considered
necessary or desirable for their own protection. The possible counter to this argument,
viz that the parties are in general entitled to couch their contract in such terms that
delictual liability is also excluded or qualified, does not in my view carry conviction.
Contracts are for the most part concluded by businessmen. Why should be law of
delict introduce an unwanted liability which, unless excluded, could provide a trap for
the unwary?’ 30
In conclusion:
‘To sum up, I do not consider that policy considerations, require that delictual
liability be imposed for the negligent breach of a contract of professional employment
of the sort with which we are here concerned.’ 31

[20] Counsel for AB Ventures pointed out, correctly, that in that case a
contractual nexus existed between the plaintiff and the defendant, but that
in this case AB Ventures and Siemens are not in contractual privity. He
submitted that in those circumstances AB Ventures was not capable of
protecting itself against the negligence of Siemens in the same way.

[21] The principle that emerged from Pilkington Brothers was that there
was no call for the law to be extended when the existing law provided
adequate means for the plaintiff to protect itself against loss.32 There is no
principial distinction between the two cases. The distinction lies only in
the form in which each plaintiff might have protected itself.

32Followed in Trustees, Two Oceans Aquarium Trust v Kantey & Templer (Pty) Ltd 2006 (3) SA 138
(SCA).

[22] If AB Ventures indeed sustained loss then the reason that it did so
was because it attracted the loss to itself in its contract with Lumwana. By
its own contractual act it took upon itself the risk of liability arising from
delay and expenses that might be caused by the default of other
contractors. The act of Siemens in causing delay and expense was no
more than the trigger for that liability to arise. Had AB Ventures not
contracted to accept that risk in the first place then it would not have
suffered the loss at all. That it had no contractual nexus with Siemens
means only that it was not capable of shifting the loss that it had brought
upon itself to Siemens contractually but that is beside the point. We are
concerned with whether it was capable of avoiding the loss, and not
whether it was capable of shifting it elsewhere, and clearly it was capable
of doing so.

[23] Indeed, the standard-form general conditions of the construction
contract that AB Ventures concluded with Lumwana anticipated that
there might be delay caused by defective performance by other
contractors and clause 8.4 entitled AB Ventures to an extension of time
for completion if that came about. Whether or not that clause protected
AB Ventures in the present circumstances is not an issue that is before us.
I refer to it only to illustrate how it might have protected itself. No doubt
it could also have protected itself against additional expenses in a similar
way. The only reason that the case is before us is that AB Ventures took
liability upon itself when it might just as well not have done so.

[24] It was submitted that there is no certainty that AB Ventures would
have secured the contract had it insisted on excluding liability caused by
the default of other contractors or sub-contractors and that evidence
should be required on that point. Whether or not it would have secured

the contract is immaterial. It is not entitled as of right to secure a contract
and has no cause for complaint if it chooses to contract on unfavourable
terms. The question to be asked is only whether the law calls for
extension to recover loss where the law already provides a means for it to
be avoided. Pilkington Brothers answered that in the negative and the
same must be said for this case.

[25] In my view the exception was correctly upheld and the appeal
should be dismissed with costs that include the costs of two counsel.
