1 By a summons dated 19 January 2007 the second defendant by counterclaim, Steuler Industriewerke GmbH ("Steuler"), sought leave now for then to amend its defence to the counterclaim brought by the defendant/plaintiff by counterclaim, WMC (Olympic Dam Corporation) Pty Ltd ("WMC") so as to rely on the version of its amended defence filed and served on 20 December 2006. WMC had previously sought, by a summons dated 9 November 2006, an order striking out certain paragraphs of an earlier version of Steuler's defence. Following discussions between the parties, agreement was reached on a number of the matters in dispute between the parties. The only issue remaining for my determination is whether the amendment should be refused because, whereas Steuler once pleaded that certain things had been done or agreed by the plaintiff/first defendant by counterclaim, Protec Pacific Pty Ltd ("Protec"), it now sought to plead that in some cases they had been done or agreed by Protec Pacific (NSW) Pty Ltd ("Protec NSW") and in other cases by one or other of the Protec Pacific companies. WMC opposed leave being given to Steuler to rely on this new part of the pleading on the ground that it would be prejudiced by the late amendments in that it would now be statute barred from joining Protec NSW as a defendant to the counterclaim.
2 The issue about which Protec Pacific company had played what role arose in the following way. It appears from the material before me that Protec Pacific was a corrosion protection business which in 1997 was operated through two companies, Protec Pacific (Tas) Pty Ltd and Protec Pacific (NSW) Pty Ltd. Between 6 October 1982 and 5 July 1993 that Protec was known as Protec Pacific Pty Ltd, from 6 July 1993 to 4 May 1998 it was known as Protec Pacific (Tas) Pty Ltd and on 5 May 1998 it changed its name back to Protec Pacific Pty Ltd. The principal place of business of Protec between 1 March 1991 and 30 December 1997 was in Burnie in Tasmania. On 31 December 1997 it changed its principal place of business to an address in Fairy Meadow in New South Wales, the registered office and principal place of business of Protec NSW. That company had been registered on 15 July 1993.
3 Steuler is a German company which carries on the business of manufacturing, designing, supplying and installing high-density polyethylene ("HDPE") lining products and systems which are marketed under the trade name Bekaplast. In April 1997 Steuler entered into a co-operation agreement with "Protec Pacific, Wear & Corrosion Control Specialists", by which Steuler appointed that entity as its sole and exclusive distributor for Steuler products in Australia and New Zealand. The agreement did not specify which Protec company was the party to the contract. It was signed by Mr Howard Smith, the managing director of both companies, for "Protec Pacific" and the common seal of Protec NSW appeared next to his signature.
4 In early 1997 Protec Pacific, by which I mean one or other or both Protec companies, prepared a tender proposal for the supply and installation of Bekaplast linings in the concrete tanks and ponds forming part of the copper and uranium solvent extraction area at WMC's mine at Roxby Downs in South Australia. This tender was part of WMC's Olympic Dam expansion project. Steuler assisted Protec Pacific in the preparation of the tender. By a facsimile dated 16 July 1997 WMC confirmed its verbal advice that it had awarded the contract to Protec NSW and issued a purchase order to it. That company, in turn, issued a purchase order to Steuler dated 15 July 1997. It also issued a number of other documents to Steuler between July and October 1997. In some Steuler shipping documents dated May and June 1998 Protec NSW was referred to, although the more common description was simply "Protec Pacific".
5 Around March or April 1998 WMC split its July 1997 contract into a purchase order covering the design, fabrication, testing, packaging and shipping of the lining and a contract for the on-site installation and testing of the lining. A revised purchase order dated 10 April 1998 was issued to Protec NSW. The on-site service agreement dated 13 June 1998 was made between WMC and "Protec Pacific Pty Ltd (ACN 060 386 807)". By then, that was again the name of Protec, but the ACN was that of Protec NSW. By a facsimile dated 15 June 1998 Mr Smith wrote to WMC confirming acceptance of the award of the contract by "Protect Pacific Pty Ltd". It was signed by Mr Smith "for and on behalf of Protec Pacific Pty Ltd". Nevertheless, it was said that all of the payments by WMC were made to Protec NSW and were banked by that company.
6 Protec Pacific commenced work on the WMC site in June 1998. There were problems with the installation work, including buckling of lining materials and liquid leaking from welded joints in the lining. In October 1998 Steuler provided a team of welders to assist with the installation. Following a dispute with WMC Protec Pacific left the site. Subsequently, WMC removed and replaced the lining with a different material.
7 On 12 November 1999 Mr Smith and Steuler entered into two written agreements. The first agreement was a sharesale agreement whereby Mr Smith agreed to sell, or grant options to sell, to Steuler 50% of his shares in Protec, although subsequently Steuler only purchased 12.5% of the shares. Mr Smith also agreed that he would arrange for Mr Michael Steuler, the managing director of Steuler, to be appointed a director of Protec; that he would delete the reference to "Protec" in the name of Protec NSW and not seek to incorporate any other company utilising the name "Protec"; and that any plant and equipment used by Protec in its business and which had in the past been owned by Protec NSW would be transferred to Protec for the sum of one dollar. Further, the parties acknowledged that "all trading activities of the business will be operated by Protec Pacific Pty Ltd and have been effectively since 1 July 1998." The second agreement was a shareholders agreement which provided, among other things, that unless otherwise agreed Protec would exclusively work with Steuler in Australia and New Zealand and that Steuler would exclusively use Protec for the installation of all of its products in those countries and that Mr Smith and Steuler would each be entitled to appoint one director to the Board of Protec.
8 According to an affidavit by Mr Smith the negotiations, which resulted in the two agreements being executed in November 1999, had commenced in about January 1998. He said that the agreement was that Steuler would purchase a stake in Protec's business effective from 1 July 1998, so that it could receive dividends from that financial year.
9 It can be seen, therefore, that there is some confusion surrounding which Protec Pacific company entered into the relevant agreements with WMC and Steuler in 1997 and 1998. However, for the reasons given below, it is not necessary to decide this question or the question of what effect the two November 1999 agreements had on this issue.
10 What is clear is that, for whatever reason, Protec acted on the basis that it was the company which had contracted with WMC because on 19 June 2000 Protec issued a generally endorsed writ seeking payment by WMC of over $2.1 million for work performed on the site of the Olympic Dam expansion project. Protec's statement of claim was delivered in August 2000. It pleaded that the debt was owing pursuant to two agreements with WMC made respectively on or about 31 March and 13 June 1998. WMC delivered its defence in September 2000, in which it admitted that it had entered into an agreement with Protec in June 1998, although its scope and effect was disputed. WMC also counterclaimed against Protec for damages for breach of the June 1998 agreement. Thus, WMC also accepted that its contractual arrangements had been with Protec.
11 On 18 December 2001 WMC joined Steuler as the second defendant by counterclaim by filing and serving its third amended defence and counterclaim on Steuler pursuant to the leave granted by the Court that day. Steuler filed its notice of appearance on 9 January 2002. On 31 May 2002 the Court ordered that WMC have leave to file and serve its fourth amended defence and counterclaim. By agreement between the parties' solicitors, Steuler's defence had been delayed pending delivery of this new pleading. On 10 July 2002 Steuler filed its defence to WMC's latest counterclaim. Steuler's pleading consisted largely of denials and not pleading to paragraphs said to make no material allegations of fact against it. One presently relevant part of the defence was that, although it denied the allegation that Protec and Steuler had both prepared a tender or proposal to WMC by a letter dated 27 April 1997 "in conjunction with one another" and were its "joint authors", Steuler admitted that it provided information to Protec by a number of communications between them in March and April 1997.[1]
12 On 29 July 2004 WMC filed its second amended defence and fifth amended counterclaim against Protec and second amended counterclaim against Steuler pursuant to an order made on 11 June 2004. Relevantly, WMC pleaded that Protec and Steuler had engaged in misleading and deceptive conduct contrary to s.52 of the Trade Practices Act 1974 ("the TPA") by making numerous false express and implied representations about the goods and their businesses in April, May and July 1997, and by making false post-contractual representations between about July 1998 and April 1999. Further or alternatively, WMC pleaded that Protec and Steuler contravened s.53 of the TPA and further or alternatively that Steuler had contravened s.75B of the TPA by aiding and abetting Protec to breach s.52 and s.53 of the TPA. WMC also pleaded a case in negligent misstatement against both Protec and Steuler. WMC's damages were said to exceed $22 million.
13 Steuler filed its defence to the second amended counterclaim against it on 8 December 2004. This was a substantive pleading which contained a number of positive allegations by Steuler of the role played by Protec, such as:
