Factual Circumstances
20The factual circumstances giving rise to the proceedings are fully described in the judgment at first instance ([2010] NSWSC 86). The following are particular matters that are relevant to the determination of this appeal.
21On 5 December 2001 Mr Michael Prescott of Prescotts, barristers and solicitors practising in South Australia, wrote to Kreindlers stating that "I confirm that I act as the representative of the families of the deceased in respect of [the aircraft accident of 31 May 2000]" and that "I confirm that on behalf of the families of all of the deceased, we wish to instruct your firm to act in relation to bringing proceedings against [the aircraft and engine manufacturers]".
22The letter contained a list of further representatives of the various deceased. In that list Mr Prescott identified himself and Turner Freeman, solicitors practising in Sydney, as representatives of the family of the late Mr Marshall.
23By letter of 7 February 2002 Mr Prescott reported to the solicitors representing the families of the various deceased, including Turner Freeman, about a trip to the United States that he and Mr Greenwell of counsel had taken "for the purpose of further investigations into the potential claim and to try and come to arrangements with the American Attorneys Kreindler & Kreindler of New York". It appeared from the letter that his discussions with Kreindlers included negotiations as to Kreindlers' fees.
24On 22 February 2002 this Court upheld an appeal against an order made in Ms Carruthers' favour under the now repealed Family Provision Act 1982 ([2002] NSWCA 47). The Court took the view that Ms Carruthers had not shown that she had been left by the late Mr Marshall without adequate provision for her proper maintenance. The Court noted that whilst Ms Carruthers was not a beneficiary under the will of the deceased she had received $360,000 as a result of his death from superannuation and from workers' compensation proceedings. It referred to Ms Carruthers as the de facto wife of the deceased.
25By email of 20 March 2002 Mr Prescott advised various family representatives, including Mr Terry Goldberg of Turner Freeman, that "we have, after long negotiations, been able to arrange funding for the US claim through ILF [that is, Insolvency Litigation Fund Pty Ltd] in Sydney" and requested information to enable him to complete the form of Retainer Agreements for Kreindlers and ILF so that he could "forward them [to] you for completion".
26That obviously occurred because the next day Mr Goldberg advised Mr Prescott that his clients would be coming in to execute the documents that day and that he had "informed Margaret Marshall she will be signing on behalf of Kim Marshall and Linda Carruthers".
27As the Retainer Agreements are dated 21 March 2002 it can be inferred that they were executed on that day, as had been planned. The following appeared under the signature of Mrs Marshall, who was the only signatory:
"Full Name of signatory: Margaret Lesley Marshall (Executor / Personal Representative)".
28Whilst Mr Kim Marshall did not sign the Agreement, the Marshalls' Statement of Claim in the present proceedings alleges that Mrs Marshall signed the Agreement on his behalf. There is no reason, at least at this stage of the proceedings, to doubt that that was the case.
29In his affidavit of 9 June 2009 Mr Goldberg said that he forwarded the signed Retainer Agreements to Mr Prescott to be "on-forwarded by him" to ILF and Kreindlers, as the case may be. In his affidavit of 8 May 2009 Mr Christopher Finn, the solicitor acting for Kreindlers in the present proceedings, gave evidence on information and belief that the Kreindlers' Retainer Agreement was forwarded by Prescotts to Kreindlers on 3 May 2002 and was executed by Mr Green on behalf of Kreindlers at Kreindlers' offices in New York on 16 May 2002. Mr Goldberg said in his affidavit of 9 June 2009 that a copy of the Kreindlers' Retainer Agreement signed on behalf of Kreindlers was not, so far as he was aware, provided to either Mr Prescott or Turner Freeman before the conclusion of the subsequently commenced Pennsylvania proceedings.
30The Kreindlers' Retainer Agreement included the following opening paragraph:
"Plaintiffs as surviving relatives and Personal Representatives of the seven passenger[s] killed in the crash of Piper Chieftain VH-MZK aircraft operated by Whyalla Airlines on May 31, 2000, hereby retain the firm of KREINDLER & KREINDLER, 100 Park Avenue, New York, New York to prosecute all claims in the United States of America arising out of the wrongful death and survival (estate) claims of plaintiffs and plaintiffs dependants" (White Book 1/119).
There was no express identification of the "Plaintiffs" to whom it referred.
31There were two ILF Retainer Agreements, one with each of the Marshalls. By them, ILF agreed, inter alia, to pay the costs to be charged by Mr Prescott and Mr Greenwell to the Marshalls for legal services provided in connection with the aircraft crash. The Agreements expressly provided that, whilst ILF would pay the relevant invoices, Mr Prescott and Mr Greenwell would be retained by the Marshalls.
32On 29 May 2002 proceedings were commenced in Pennsylvania by local attorneys acting on the instructions of Kreindlers against the aircraft and engine manufacturers. The Marshalls were named as plaintiffs and were said in the title to the proceedings to be suing "individually and as Executors and Personal Representatives of the Estate of Neil Marshall, Deceased". In the body of the Complaint that initiated the proceedings it was said that the Marshalls commenced the proceedings "on behalf of the Estate and surviving family members of Neil Marshall". Later it asserted that the Marshalls, "the decedent's survivors and the Estate of Neil Marshall are entitled to recover full wrongful death and survival compensatory damages, including damages for loss of the decedent's earnings, loss of support, loss of services ... ".
33On 25 July 2002 Mr Goldberg of Turner Freeman sent an email to Mr Green of Kreindlers, with a copy to Mr Prescott, stating the following:
"I act for Margaret Marshall and Kim Marshall, and Michael Prescott acts for Ms Carruthers in the action relating to the death of Neil Marshall in the Whyalla Airlines crash.
I now understand that you would like us to provide you with more information as to the assessment of damages. I can only do that in respect of Kim and Margaret, but not Linda. Michael Prescott and I have an agreement that I will send material to you directly. By way of background, I advise that my clients and Linda have been involved as opposing parties in various actions in Court here over the estate of Neil Marshall, and their relationship is not good".
34In an email to Mr Goldberg of 30 July 2002 Mr Green said the following:
"The action in the US [has] been, and had to be, brought by the personal representative of the decedent's estate, but [is] brought on behalf of the estate and the decedent's survivors. If the court applies US law, each dependant survivor will obtain an award for loss of support and an award will be made to the estate for the decedent's pre-death pain and suffering.
If there are no dependent survivors, an estate accumulations award will be made to the estate and will go to the estate beneficiaries. The award for pain and suffering would not be a 'personal' recovery as I understand your question".
35On 26 August 2002 Mr Kim Marshall swore a "Declaration" for use in the Pennsylvania proceedings in opposition to a motion for dismissal of the proceedings. The Declaration included the following paragraph:
"Neil was survived by the following family members: Margaret Lesley Marshall, Kim Neil Marshall and Linda Hope Carruthers. My mother Margaret Lesley Marshall was emotionally devastated by Neil's death, I was financially and emotionally devastated by Neil's death and Linda Hope Carruthers has stated that she was financially and emotionally devastated by Neil's death".
36Ms Carruthers also swore a Declaration in August 2002 for use for the same purpose. She described herself as the "surviving de facto wife" of Neil Marshall and said that she had been "financially and emotionally devastated" by his death.
37After negotiation in the following year of a settlement of the Pennsylvania proceedings Mr Green sent an email dated 8 April 2003 to Mr Greenwell, with copies to Mr Goldberg and Mr Prescott amongst others, stating the following:
"... We need to make sure that all of the persons even arguably entitled under Australian law [agree] to the settlement distribution. We need releases signed in favor of the estate representatives and lawyers.
As you know, the Estate representatives have a fiduciary duty to all potential distributees. If a potential distributee is cut out of the settlement, they can sue the estate representative and the lawyers. No settlement money will be distributed until everyone is on board. If a particular distributee acts unreasonably in a given case, we will have to get court approval of the distribution".
38In a letter of 15 April 2003 to Mr Goldberg, Mr Fleming of Kreindlers stated the following:
"Under Pennsylvania law, since Ms. Carruthers has been recognized by an Australian court as the de facto spouse, she would have a claim to the wrongful death recovery assuming that Australian law treats de facto spouses as de jure spouses in these types of actions".
39Further correspondence ensued, culminating in the requirement of Kreindlers, to which I have earlier referred, that prior to payment of the settlement proceeds to the Marshalls they obtain in Australia a court determination that Ms Carruthers was not entitled to a share of those proceeds. In the subsequent proceedings concerning Ms Carruthers, Mr Green gave evidence that the making of this requirement reflected the practice of experienced and reasonably prudent US litigation attorneys (affidavit of 23 April 2004 at [10]).
