12 The document of 10 September therein referred to is the letter of 10 September 1999 referred to in the particulars. It contains what are described as heads of agreement. The principal provisions in the document are as follows.
3. Default events which render within 7 days of demand payment of principal and interest calculated to end of term in relation to the loan include:
A. The non-repayment of any scheduled item of interest or principal …………………………………………
E. The failure to direct all pack and unpack in Sydney, Melbourne and Brisbane and Sydney air-freight to Port Botany/MPG facilities including transport or as the lender shall advise at agreed cost in line with market conditions.
……………………………………………..
4. AFA Freight Management (USA) Inc will direct all work of pack and unpack LCL nature in Sydney, Melbourne and Brisbane, together with Sydney air freight to the corporations that the lender shall direct. Such work shall include transport.
13 As indicated above, it is agreed for present purposes that the stipulations in cl 3E and cl 4 of the letter are unlawful as contravening s47 of the Trade Practices Act. Sully J held that the offending provisions of the deed of guarantee as incorporated into the deed in terms of the letter of 10 September 1999 were severable. On that basis he upheld the plaintiff's notice of motion and ordered that paras 5, 6, 7 and 8 of the further amended defence and the whole of the defendants' cross claim be struck out. There were consequential orders for costs. See SST Consulting Services Pty Limited v Rieson & Anor [2001] NSWSC 804.
14 His Honour's reasons are given in paras 19 to 24 of the judgment which I set out.
The first practical question posed by that submission is whether the offending provisions of the Deed of Guarantee, as incorporated into the Deed in terms of the letter of 10 September, are severable. If they are, then the operation of section 4L of the Trade Practices Act would, without more, entitle SST to succeed in its present strike-out applications.
The principles of law governing this question of severability are well established. They are summarised conveniently in the judgment of Wilcox J in Pont Data Australia Pty Limited v ASX Operations Pty Limited & Anor [1989] 21 FCR 385 at 425, 426.
The correct application of those principles to the given facts of the present case entails, in my opinion, the following propositions:
[1] The Deed of Guarantee assures, relevantly, to SST two advantages:
(a) The advantage of being paid back, in the form of interest, a greater sum of money than the principal sum advanced by it to the principal borrower and guaranteed by the present defendants; and
(b) The benefit flowing from the exclusive dealing provisions of the Deed of Guarantee and the incorporated terms of the letter of 10 September.
[2] The advantage referred to in [1a] above is a normal and lawful commercial advantage deriving from a normal and lawful agreement to lend money at interest. The correlative obligation of the guarantors is, also, a normal and lawful obligation deriving from a normal and lawful commercial transaction.
[3] The benefit noted at [1b] above is proscribed by section 47 of the Trade Practices Act . If SST were now suing the two defendants in the principal proceedings upon the basis of a default manifested by a breach of the proscribed exclusive dealing requirements of the Deed of Guarantee and its associated Heads of Agreement, then I would think as at present advised, that the better view would be that a Court should not lend its aid to the enforcement of a clearly illegal contractual term.
[4] That situation does not, however, arise in the present case. It is clear from the terms of the Statement of Claim in the principal proceedings that the defaults alleged to give rise to liability in the two defendants are defaults unrelated to the unlawful provisions as to exclusive dealing.
[5] The elimination of the unlawful portions of the Heads of Agreement from the Deed of Guarantee would not entail, in my opinion, a fundamental change to the kind of contract which is embodied in the Deed of Guarantee. One only of a number of unrelated default-triggering events would be excluded; and there would remain on foot a clear, coherent and normal commercial engagement for the advance of a large sum of principal on loan, and for its repayment with interest; such repayment being secured by a normal commercial guarantee.
[6] In those circumstances, it is my opinion that the offending portions of the Heads of Agreement as incorporated into the Deed of Guarantee are severable; and that the balance of the obligations embodied in the Deed of Guarantee and the incorporated Heads of Agreement are valid and enforceable at the instance, relevantly, of SST.
In the light of that conclusion it is, strictly speaking, unnecessary to consider the question whether, had I come to the view that the offending provisions of the Heads of Agreement as incorporated in the Deed of Guarantee were not severable, the inclusion of those offending provisions would have rendered the entirety of the Deed of Guarantee unenforceable at the instance of SST. I propose, however, and in deference to the extensive submissions made by both counsel on the point, to express briefly my opinion in that connection.
The relevant guiding principles are to be derived, in my view, from the decision of the High Court of Australia in Yango Pastoral Company Pty Limited & Ors v First Chicago Australia Limited & Ors [1978] 139 CLR 410. The application of those principles to the given facts of the present case entail, in my opinion, the following propositions:
[1] The proper construction of section 47 of the Trade Practices Act reveals a public policy that exclusive dealing of the kinds proscribed by section 47 ought not to be permitted because they tend to inhibit what Parliament regards as a proper level of economic competition in the community.
[2] That public policy can be enforced, and enforced in very stringent ways, by the appropriate penalty provisions of the Act. Any breach of the law as to exclusive dealing can attract draconian pecuniary penalties and a wide range of injunctive and other remedial measures.
[3] There is no reason to think that those remedies, if enforced resolutely according to law, will be inadequate, at least in a case of the present kind, to protect to the full all relevant and legitimate public interests.
[4] As I have earlier said, there is in my opinion a difference between a case in which a lender in the position of SST is seeking to enforce the very provision which has been proscribed by the Act; and the case where such a lender is seeking to have normal and lawful recourse in order to enforce normal and lawful obligations to repay the loan of a large amount of money. To deny the lender any legal recourse at all in the latter type of case seems to be to be, as a matter of common sense, unconscionable, and to confer upon the guarantors a benefit that seems to me to amount, in a real and practical way, rather than in any pedantic technical sense, to unjust enrichment.
Had it been necessary to do so, I would have concluded. Therefore, that on the given facts of the present case, the guarantors were not entitled as a matter of law to plead as a complete defence the offending provisions of the Heads of Agreement as incorporated into the Deed of Guarantee upon the basis of which they have been sued.
15 It can be seen that he held, in effect: first, that the offending provisions of the deed of guarantee were so clearly severable as to render the pleaded defence and cross-claim untenable; and secondly, that the inclusion of the offending provisions did not spell invalidity as distinct from exposure to the penal and injunctive sanctions of the Trade Practices Act.
16 In my view, the relevant portions of the pleadings should not have been struck out because they present triable issues. I respectfully disagree with his Honour's conclusions on both the matters referred to above. I say this in essence for three reasons, explaining that I am only concerned to show that the matter should not have been summarily disposed of.
17 First, the application of the law as to severability is contestable in its impact in the present case. The circumstances in which a term made illegal by statute may be severed from the remainder of the contract are usually expressed in the frequently approved test stated by Jordan CJ in McFarlane v Daniell (1938) 38 SR(NSW) 337 at 445.
18 It should, however, be observed that in the words of McHugh J in Humphries v The Proprietors "Surfers Palms North" Group Titles Plan 1955 (1994) 179 CLR 597 at 619:
However [Chief Justice Jordan's test] is not an exclusive test. The test of severability is a flexible one. 'There are not set rules which will decide all cases.
19 The passage in single quotes is taken from the Privy Council decision in Carney v Herbert [1985] AC 301 at 311. In Carney the Privy Council said that there are two matters to be considered. First whether, "as a matter of construction" or intention the lawful part can be severed from the unlawful part and second, "whether despite severability there is a bar to enforceability" arising out of the illegality.
20 I say no more than that the severability issue is complicated in the present case by the possibility that the loan transaction itself might be tainted by the overarching impact of s47 of the Trade Practices Act. If the loan is thus affected then it is at least arguable that the guarantee is affected. All the more so since it refers in terms to the offending parts of the heads of agreement (see the reference to "positive acts to be done").
21 Second, it is to my mind debatable whether s4L of the Trade Practices Act has the effect asserted by the plaintiff and implicitly found by Sully J. Section 4L provides;
