Background
3 At the ex parte hearing on 1 February 2011, the Suzlon parties sought and later obtained leave to join CS Group and then serve it in Switzerland (see Beluga (No 5) 278 ALR at 73 [83]) on the basis identified in paragraph 14C of the cross-claim, namely:
"At all material times, the Fifteenth Second Cross Defendant (Credit Suisse) was a banking company incorporated in Switzerland whose business units or division included Credit Suisse Private Banking and Credit Suisse Trust Limited."
4 On 29 June 2011, CS Group refused to accept service of the new pleadings by the Supreme Court of the Canton of Zurich, as an authority for the purposes of the Hague Convention, because they and other documents were not accompanied by translations into German. A certificate to this effect by the Zurich Court dated 30 June 2011 was filed in this Court on 12 July 2011. The evidence before me is that, under Swiss law for the purposes of the Hague Convention, it is not necessary to serve a translation of a document unless the party to be served refuses to accept service of the untranslated document without an accompanying translation, as happened here.
5 On 1 July 2011, two days after CS Group had written to the Zurich Court refusing to accept service, its Australian solicitors, Mallesons Stephen Jaques wrote to the Suzlon parties' solicitors, HWL Ebsworth, asserting that CS Group was not a proper party to the new pleadings "… as it does not operate a banking or trading business and has no client accounts or client relationships of any kind with any person". The letter claimed that CS Group had been joined incorrectly. It insisted that the Suzlon parties file a notice of discontinuance against CS Group by 8 July 2011, failing which it would file a notice of motion seeking orders to set aside the orders for its joinder and service made on 1 February and 4 March 2011 and for indemnity costs.
6 On 4 July, HWL Ebsworth replied saying that they had understood that Credit Suisse Private Banking, Zurich, for which Ms Lea Klee had worked, was a division of CS Group, adding a request that, if this were incorrect, CS Group identify her employer at the relevant time and the entity that conducted the business of Credit Suisse Private Banking, Zurich division. Mallesons Stephen Jaques replied on 6 July repeating its earlier assertion that CS Group did not operate any banking business and stating that they had no instructions as to Ms Klee's employer other than that she was never employed by CS Group. They again insisted that the Suzlon parties file a notice of discontinuance.
7 By 7 July, Joseph Hurley of HWL Ebsworth, the Suzlon parties' solicitor, had made further enquiries about CS Group's legal structure. Mr Hurley deposed in his affidavit of 29 July 2011 that, at the time of the application for joinder:
he had believed that the entity described as CS Group was the relevant Credit Suisse entity that had a business division named Credit Suisse Private Banking and that it employed Ms Klee;
he understood that an entity with the name Credit Suisse Group AG also had an office in Sydney but that it was not the same as the Swiss entity CS Group that he believed was Ms Klee's employer.
8 Mr Hurley deposed that on 7 July 2011 he conducted an internet search that showed that Walter Berchtold was "the Chief Executive Officer, Private Banking", employed by Credit Suisse AG. Based on this search Mr Hurley said he now believed that Credit Suisse AG was Ms Klee's employer and that it was the entity with which Credit Suisse Private Banking maintained the bank accounts referred to in the new pleadings.
9 On 7 July, HWL Ebsworth wrote to Mallesons Stephen Jaques in response to their letter of 6 July. HWL Ebsworth maintained that it was not clear from Credit Suisse's website that there was any difference in the entities CS Group, Credit Suisse Group AG and Credit Suisse Group Limited and that the directors appeared the same. The letter made no mention of Credit Suisse AG or Mr Berchtold, but again asked about which Credit Suisse entity had employed Ms Klee and was the proper cross defendant. It asserted that if there had been a misnomer or misjoinder, the Court could order correction under:
O 13 r 2 of the old Rules (sub-rules (4) and (5) allowed an order correcting the name of a party where there had been a mistake in the name or identity of a party notwithstanding that this may have the effect of substituting another person as a party);
O 6 rr 7 and 8 of the old Rules (that provide that proceedings would not be defeated by reason of misjoinder of a party (O 6 r 7) and that the Court may make an order for the joinder of a person who ought to have been joined (O 6 r 8)).
10 Mallesons Stephen Jaques replied the next day confirming that CS Group, Credit Suisse Group AG and Credit Suisse Group Limited were the same entity and that it did not have a private banking business. They said that the Suzlon parties had purported to make out a prima facie case against CS Group and that this was misconceived. They denied that there was any misnomer of CS Group and asserted that it was the victim of a misjoinder citing Davies v Elsby Brothers Ltd [1961] 1 WLR 170; [1960] 3 All ER 672. The letter argued that any amendment to correct the name CS Group to some other name would necessarily have the effect of removing it as a party and substituting another person. Thus, it contended, CS Group was not a proper party and the Suzlon parties ought to discontinue their cross claim against it.
11 In his affidavit, Mr Hurley noted that the 2010 annual report of CS Group stated that Credit Suisse AG was, first, "… the Swiss bank subsidiary of the Group [and] is substantially similar to the Group" and, secondly, a wholly owned subsidiary of CS Group with identical directors and registered offices. The report stated that the expression "the Group" was a reference to CS Group itself and its consolidated subsidiaries.
12 On 19 July, CS Group filed a notice of motion seeking orders that the order of 4 March 2011 granting leave to serve it in Switzerland be discharged or alternatively set aside (under O 9 r 7(1)(d) or (a) of the old Rules) and for the Suzlon parties to pay its costs on an indemnity basis. Next, on 21 July, CS Group offered to settle on a without prejudice except as to costs basis if the Suzlon parties consented to the orders it sought and paid $11,500 in costs, assessed on a party/party basis. The offer was to remain open until 4 August 2011. The letter claimed that the CS Group had incurred $19,000 in costs up to the date of the letter.
13 On 1 August 2011, the Suzlon parties filed a notice of motion seeking leave to amend the asserted misnomer of the fifteenth second cross defendant to "Credit Suisse AG" under O 13 r 2(4) or to correct the misjoinder of CS Group under O 6 r 7. The motion also sought confirmation of service on the fifteenth second cross defendant. Also on that day, Mallesons Stephen Jaques wrote to HWL Ebsworth noting that the new motion amounted to a concession that the Suzlon parties had proceeded against CS Group incorrectly. This letter repeated the offer made on 21 July.
14 On 2 August 2011, Credit Suisse AG was served at its registered office in Sydney with the Suzlon parties' notice of motion. However, it did not appear on 5 or 8 August 2011 when both CS Group's and the Suzlon parties' motions were returned. Accordingly, I have proceeded ex parte in respect of Credit Suisse AG on the Suzlon parties' motion. Next, on 3 August, HWL Ebsworth replied to Malleson Stephen Jaques' letter of 1 August. This asserted that the nomination of CS Group in the new proceedings was a misnomer based on Bridge Shipping Pty Ltd v Grand Shipping SA (1991) 173 CLR 231. The letter sought consent for an order to be made substituting Credit Suisse AG under O 13 r 2.
15 That offer was rejected on 4 August. Mallesons Stephen Jaques noted that it was now apparent that the Suzlon parties no longer contended that they had a prima facie case against CS Group. They asserted that CS Group's nomination "could not possibly constitute a misnomer" and was a misjoinder, calling in aid Bridge Shipping 173 CLR at 251, 261-262 and an earlier decision of Giles J in John R Quality Meats Pty Ltd v Cains (NSWSC 23 May 1988 unreported). The letter said that if there were a misnomer, CS Group was not able to consent to a substitution of a subsidiary because it had never been a party.
