The Decision in Caswell
20In the absence of statutory authority the Court does not have power to issue a subpoena for service in a foreign State (Ward v Interag Pty Ltd [1985] 2 Qd R 552; Re Austral Oil Estates (in liq) (1986) 7 NSWLR 440). Rule 11.5 or its predecessor (Supreme Court Rules 1970, Pt 10 r 3) has been construed as providing such statutory authority. Where there is statutory authority for the extra-territorial exercise of jurisdiction, the jurisdiction has been described as "exorbitant", although the expression has been criticised (Arhill Pty Ltd v General Terminal Company Pty Ltd (1990) 23 NSWLR 545 at 551 citing The Siskina [1979] AC 201 at 254). Where possible, statutes are to be construed conformably with the comity of nations and established rules of international law (Barcelo v Electrolytic Zinc Co of Australasia Ltd (1932) 48 CLR 391 at 423-424; Polites v Commonwealth (1945) 70 CLR 60 at 68-69; Minister for Immigration and Ethnic Affairs v Teoh (1995) 183 CLR 273 at 287; Plaintiff M70/2011 v Minister for Immigration and Citizenship (2011) 244 CLR 144 at 234).
21 In Arhill Pty Ltd v General Terminal Co Pty Ltd, Rogers CJ Comm D said of a similar earlier rule of court (at 553):
"Part 10, r 3 is in terms clear authority for the Court to give leave to serve a subpoena outside Australia. The fact that an order made pursuant to it could, in some instances, involve an infringement of the sovereignty of another country does not mean that it is a reason for holding the rule to be invalid. Nonetheless, the rule should be construed consistently with 'the established criteria of international law with regard to comity': cf [Re Tucker; ex parte Tucker] [1988] 2 WLR 748 at 758; [1988] 1 All ER 603 at 611]"
22Rogers CJ Comm D held that Part 10, r 3 of the Supreme Court Rules (the predecessor to UCPR, r 11.5) did not authorise the grant of leave for the service of a subpoena on a Japanese company in Japan (at 553). The reason was that to do so would be contrary to principles of international law and comity that require respect to be given to the sovereignty of the foreign State where that sovereignty would be infringed by the exercise of judicial power by this Court in the foreign State.
23In Re Deposit and Investment Co Ltd (1991) 30 FCR 463, Lockhart J held that a rule of the Federal Court similar to UCPR, r 11.5 was not to be read as an extension of the Court's jurisdiction. His Honour said (at 466):
"To invade the sovereignty of another country's jurisdiction and interfere with its sole power over persons present within it, stronger and clearer language is needed ..."
24In that case counsel had relied on Order 8, r 3 of the Federal Court Rules as authority for the service of examination orders under s 597 of the Corporations Law on persons resident in Hong Kong and Japan. His Honour held that although the rule was couched in very wide terms, it must be read as a procedural provision and not as an extension of the Court's jurisdiction over persons outside Australia. (Examination summonses pursuant to ss 596A and 596B of the Corporations Act 2001 (Cth) may be issued to persons overseas pursuant to UCPR Pt 11.5 and its equivalents because of the express extra-territorial operation of that Act provided by s 5 (Waller v Freehills [2009] FCAFC 89; (2009) 258 ALR 67 at [53]-[58]).)
25Other decisions to the same effect of Arhill and Re Deposit and Investment Co. Ltd include Aetna Pacific Securities Limited v Hong Kong Bank of Australia Limited (Supreme Court of NSW, Giles J, 29 April 1993, unreported; BC9301701); News Corporation Limited v Lenfest Communications Inc (1996) 40 NSWLR 250 at 261; Gao v Zhu [2002] VSC 64 at [13]; Stemcor (A/sia) Pty Ltd v Oceanwave Line SA [2004] FCA 391 at [11]; Ives v Lim [2010] WASC 136 at [18]; Levy Schneider v Caesarstone Australia Pty Ltd [2012] VSC 126 at [6]; and Federal Treasury Enterprise (FKP) Sojuzplodoimport v Spirits International NV [2007] FCAFC 43; (2007) 157 FCR 558 at [13]-[16]. In all these cases it has been held either that the relevant rule does not confer power to issue a subpoena or make an order requiring the production of documents from a person overseas, or that, assuming such power to exist, it would not be proper to exercise the power because to do so would invade the sovereignty of the foreign State. Some cases have held that it is only in exceptional or most exceptional circumstances that such a power should be exercised (e.g. Mackinnon v Donaldson, Lufkin and Jennette Securities Corporation [1986] Ch 482 at 493; Stemcor (A/sia Pty Ltd v Oceanwave Line SA at [11]; Gao v Zhu at [15]; but cf Hua Wang Bank Berhad v Commissioner of Taxation [2013] FCAFC 28; (2013) 296 ALR 479 at [15]-[26]). (Different considerations may apply if the overseas person is a party in respect of whom the Court has jurisdiction, as in Hua Wang Bank Berhad v Commissioner of Taxation at [26]).
26In Sweeney v Howard [2007] NSWSC 262, Windeyer J dismissed a notice of motion seeking to set aside a subpoena served on the applicant in the United Kingdom by way of substituted service on her solicitors. His Honour said (at [11]):
"[11] I consider that r 11.5 does give authority for a subpoena to be served outside Australia and, in the circumstances of the present case, there is nothing in the comity of nations which would require the court to resist this. According to information made public by the Attorney-General, the government of the United Kingdom does not consider service in the United Kingdom of a subpoena issued out of a foreign court to be an interference with the governance of that country, or an interference in its sovereign affairs. Nevertheless, the position has at least ordinarily been accepted that there is no jurisdiction to serve this type of process overseas. It is true that in cases where the court has assumed extended jurisdiction under Pt 11 of the Rules originating process can, as a matter of course, be served overseas. However, in such a case, if there is no appearance, leave to proceed is necessary before the matter can be taken further."
27Windeyer J did not further identify the information made public by the Attorney-General that the Government of the United Kingdom does not consider service in the United Kingdom of a subpoena issued out of a foreign Court to be an interference with its sovereign affairs. There is no such evidence about the attitude of the Government of the People's Republic of China in relation to the Special Administrative Region of Hong Kong.
28In Caswell, Hallen AsJ referred to many of these cases and said:
"[101] The conclusion I draw from this survey of authority is that the court, under UCPR r 11.5, has power to authorise a subpoena to be served outside Australia, with the leave of the court, and it has power to subsequently confirm service of that subpoena. The burden of convincing the court to accept jurisdiction is on the Plaintiff. Doubt should be resolved in favour of the recipient located outside Australia and the court should be careful in acceding to jurisdiction.
[102] I then turn to the question whether leave in this case should have been granted, or whether having been granted, the subpoena should be set aside, now, on discretionary grounds. In doing so, I recognise the special need for care when exercising an extra-territorial discretionary power and the use of the phrase 'exceptional circumstances' in some of the authorities. (I take that phrase to apply to a variety of circumstances. It generally means circumstances that are unusual, or special, or uncommon, or out of the ordinary. They need not be unique, or unprecedented, or very rare, but they cannot be circumstances that are regularly, routinely or normally encountered. The circumstances may be considered either singularly or combined. No definition that limits the application of the phrase should be adopted.)
...
[112] However, all of the authorities to which I have referred, have discussed the caution that is required where there is an intrusion upon the sovereignty of a foreign state."
29With respect, the authorities establish more than that. They establish that the Court's power to grant leave to issue a subpoena to a person outside Australia is to be exercised in accordance with the principle of comity that respects the sovereignty of a foreign country, unless it is shown that the foreign country does not object to the purported exercise of judicial power by this State against persons in the foreign State. Thus in Spirits International, the Full Court of the Federal Court set aside an order of a primary judge requiring discovery against an overseas third party whom the primary judge considered to be the "real" applicant on the cross-claim saying:
"[13] ... In considering, however, whether there was an error of principle in making the order, its effect must be looked at to see whether appropriate regard has been paid to international comity and to whether the order involves an inappropriate intrusion upon the sovereignty of a foreign state.
[14] It is in these respects that we are persuaded that his Honour made an error of principle. His Honour was undoubtedly concerned about the invasion of the sovereignty of a foreign state. He considered the principles referred to in Stemcor (Australasia) Pty Ltd v Oceanwave Line SA [2004] FCA 391 at [12] per Allsop J; Arhill Pty Ltd v General Percival Company (1990) 23 NSWLR 545 and Aetna Pacific Securities Ltd v Hong Kong Bank of Australia Ltd (unreported, Supreme Court of New South Wales, Giles J, 29 April 1993) in respect of applications for leave to serve subpoenas outside the jurisdiction upon a non-party foreign entity. Nevertheless, his Honour did not, we consider, act with the caution that the principled exercise of the discretion requires where there is an intrusion upon the sovereignty of a foreign state.
[15] The nature of the required caution was explained by Rogers CJ Comm D in Arhill 23 NSWLR 545. His Honour there emphasised the need for restraint upon subjecting a foreign entity (not, of course, in that case a foreign state) to local jurisdiction and the need to construe any powers conferred upon the court 'consistently with the established criteria of international law with regard to comity' (at 553). It is important to note that, as in this case, the third party affected by the order in Arhill 23 NSWLR 545 was regarded by the judge as a 'real' party to the action (at 555). Despite this, the subpoenas were set aside. The approach in Arhill 23 NSWLR 545 was adopted by Allsop J in Stemcor [2004] FCA 391 at [12] where his Honour said that 'the service of an order upon a German company demanding that it do something in Australia on pain of punishment in proceedings to which it has not submitted is such an invasion of German sovereignty as not to be contemplated except in the most exceptional circumstances'. His Honour there was discussing service in Germany of a subpoena issued by an Australian court, in circumstances where there was no sanction for non-compliance. Whilst the only sanction for non-compliance in this case would have been a stay of the main proceedings, which would have operated only indirectly on the Russian Federation, we are of the view that the approach adopted in Arhill 23 NSWLR 545 and Stemcor [2004] FCA 391 ought to have guided the exercise of the discretion in the present case."
30The better view, consistently with the principle that statutes are to be construed conformably with the comity of nations and established rules of international law, where that is possible, is that this is a restriction on power and not merely a guide to the proper exercise of discretion. But if the question is characterised as one of discretion, all of the cases, except Sweeney v Howard, where issues of comity did not arise, are authority for the proposition that the discretion to make such orders against an overseas non-party should not be exercised where to do so would be to infringe the sovereignty of the foreign State.
