9The late Neil Marshall ("the deceased") was the husband and father of the first and second named plaintiffs respectively. In or about June 1995, the deceased separated from the first named plaintiff and commenced to reside in a de-facto relationship with Linda Carruthers ("Carruthers"). In 1996 a property settlement was reached between the deceased and the first named plaintiff. However, no proceedings were brought seeking dissolution of the marriage.
10On 31 May 2000 an aircraft in which the deceased was a passenger crashed near South Australia. The deceased, along with some twenty other passengers and the pilot, died as a result of that crash.
11Following the deceased's death, Carruthers brought proceedings pursuant to the Family Provision Act seeking an order that provision be made to her from the deceased's will. At about the same time, she also commenced proceedings in the Compensation Court of NSW, seeking a death benefit on the basis that she was the de-facto spouse of the deceased.
12On 26 July 2001, in the proceedings brought in the Compensation Court, Carruthers received a death benefit of approximately $200,000.00 which was paid by the GIO, who was the Workers Compensation Insurer of the deceased's employer, the Australian Manufacturing Workers Union. Although Carruthers was successful at first instance in the proceedings brought pursuant to the Family Provision Act, the Court of Appeal ultimately concluded that she was not entitled to any provision from the deceased's will (see Marshall v Carruthers [2002] NSWCA 47), and that the deceased's estate was held by the first named plaintiff on trust for the second named plaintiff (who at that stage had not attained the age of 18 years). The finding which had been made at first instance that Carruthers and the deceased were in a de-facto relationship at the time of the deceased's death was not the subject of any challenge.
13On or about 22 May 2002 a series of separate sets of proceedings were commenced in the United States District Court for the District of Pennsylvania ("the United States proceedings"). Those proceedings were brought by the surviving family members of each person who had died in the air crash, against Textron Lycoming Inc. ("Textron"), the manufacturer of the engines that were attached to the aircraft. The first and second named plaintiffs were plaintiffs in one of those actions, all of which were ordered to be tried together. All of the plaintiffs in the United States proceedings were represented by a firm of lawyers in New York, Messrs Kriendler and Kriendler ("Kriendlers"). The United States proceedings were required to be commenced, for jurisdictional reasons, in the District of Pennsylvania. That necessitated Kriendlers engaging another lawyer in Pennsylvania to act as their agent.
14The defendant in the current proceedings before this court is a South Australian lawyer who was instructed by some (but not all) of the plaintiffs in the United States proceedings. To the extent that he was not instructed by the remainder of those plaintiffs (including the first and second named plaintiffs in the current proceedings before this court) he appears to have acted as, for want of a better term, the "Australian representative" of Kriendlers. In particular, it appears to have been part of his role to liaise with the Australian legal representatives of those plaintiffs in the United States proceedings for whom he did not act, and to appraise them of aspects of the progress of such proceedings.
15On 21 February 2003 the United States proceedings were settled. As might be expected, it was necessary for various Deeds to be executed to give effect to the settlement which had been reached. Following the settlement being reached, but whilst the necessary Deeds were being prepared, Carruthers made a claim for the payment, to her, of that part of the settlement money from the United States proceedings which was due to the first and second named plaintiffs in these proceedings. She did so notwithstanding the fact that she was not, and never had been, a party to the United States proceedings.
16The notification of Carruthers' claim caused Kriendlers to advise that no part of the settlement money from the United States proceedings would be distributed to the first and second named plaintiffs in the present proceedings unless and until Kriendlers received some form of acceptable confirmation that Carruthers had no entitlement to it. In view of the advice of Kriendlers, the first and second named plaintiffs brought proceedings in this court against Carruthers seeking (inter alia) declaratory relief as to their entitlement to a share of the settlement monies from the United States proceedings ("the Carruthers proceedings"). Carruthers filed a cross claim in those proceedings seeking declaratory relief as to her entitlement.
17Initially, Carruthers was represented in those proceedings by the present defendant. When this became apparent, the first named plaintiff sought and obtained (in separate proceedings) an injunction against the defendant restraining him from, in effect, acting against her. From that point onwards, Carruthers was represented in the Carruthers proceedings by Teece Hodgson and Ward ("THW"), a firm of solicitors in Sydney.
18Ultimately, the first named plaintiff succeeded in obtaining relief against Carruthers in the Carruthers proceedings, the effect of which was to declare that Carruthers had no entitlement to any part of the settlement monies from the United States proceedings. In addition, the first and second named plaintiffs received the benefit of an order for costs in their favour. However, almost the entirety of the settlement monies from the United States proceedings to which the first and second named plaintiffs were adjudged to be entitled had, by that time, been expended in costs.
19Accordingly, the first and second named plaintiffs commenced the present proceedings against the defendant seeking, by way of damages, the costs which were expended. It is in these proceedings that the current notices of motion have been brought.
20There are a number of aspects of the Carruthers proceedings which are relevant in determining the present privilege claims, and to which I should make specific reference.
21As I have noted, upon the present defendant being restrained from acting for Carruthers in the Carruthers proceedings, Carruthers was thereafter represented by THW.
22Turks Legal were the solicitors for the GIO. They retained Mr Jenkins of counsel to advise the GIO. The GIO was never itself a party to the Carruthers proceedings although it had, in the circumstances which are more fully set out below, an interest in the outcome of those proceedings.
23Mr Jenkins acted for Carruthers in the Carruthers' proceedings. He did so originally on the instructions of the defendant, and later on the instructions of THW.
24Mr Hick's affidavit of 26 June 2012 establishes that the following funding arrangements were in place:
(i)Turks Legal, as solicitors for the GIO, submitted its tax invoices to the GIO for payment;
(ii)THW, initially as the defendant's agent and later as the solicitors for Carruthers, submitted tax invoices for work undertaken by them in the Carruthers proceedings, to the GIO for payment;
(iii)Mr Jenkins, as counsel for Carruthers in the Carruthers proceedings, provided his tax invoices to Turks Legal who, in turn, forwarded them to the GIO parties for payment.
