(2) The effect of Swiss banking secrecy laws
40 In the present circumstances, the Suzlon parties opposed the Banks' applications to be relieved from answering the notices to produce based on the effect of Swiss law. The documents called for in each notice are highly likely to be held by the Banks in Switzerland. The Suzlon parties suggested that electronic documents could be kept on a server that is not in Switzerland. That suggestion is speculative and there is no evidence to support it. I am not satisfied that any officer of any of the Banks could access outside Switzerland, including from any server, any record sought in the notices to produce.
41 Ms Wassmer's evidence of Swiss law suggests that there is a strong likelihood that if the Banks are required by this Court to answer the notices to produce, they, and the officers in Switzerland who assist in the production of documents, would breach Art 47 and or Art 273. That raises the question of what is each Bank to do? Should it obey this Court's requirement in r 30.28(3) to produce the documents, or risk incurring a sanction, such as its interlocutory applications being dismissed and judgment being entered against it (see e.g. rr 5.22(a), 5.23(2), 1.32 and s 37P of the Federal Court Act)? And, if it does comply with the notice to produce, the Bank will be likely to have committed serious criminal offences in Switzerland, the place of its head office. As Lehane J said in Australian Securities Commission v Bank Leumi Le-Israel (Switzerland) (1996) 69 FCR 531 at 552G, Lockhart and ML Foster JJ agreeing:
"… it is no light matter to enforce Australian laws in circumstances which infringe the legislative policies of other countries …"
42 His Honour made clear that the Court retained a discretion to refuse specific relief if, by granting that relief against a person, he or she would be compelled to breach the law, including a foreign law: Bank Leumi 69 FCR at 545B-C; see too Bank of Valletta plc v National Crime Authority (1999) 164 ALR 45 at 57 [48], 59 [55] per Hely J, affirmed by the Full Court in Bank of Valletta plc v National Crime Authority (1999) 90 FCR 565 at 567 [10] per Wilcox, Whitlam and Lehane JJ. This reflects an important aspect of international law, namely, the caution or self restraint exercised ordinarily by one sovereign power in respect of the governmental powers of a foreign sovereign over who and what is in that foreign sovereign's territory. In CSR Ltd v Cigna Insurance Australia Ltd (1997) 189 CLR 345 at 395-396, Dawson, Toohey, Gaudron, McHugh, Gummow and Kirby JJ quoted with approval the following passage in which the Supreme Court of the United States explained this aspect of "comity" (Hilton v Guyot 159 US 113 (1895) at 163-164 per Gray J):
" "Comity", in the legal sense, is neither a matter of absolute obligation, on the one hand, nor of mere courtesy and good will, upon the other. But it is the recognition which one nation allows within its territory to the legislative, executive or judicial acts of another nation, having due regard both to international duty and convenience, and to the rights of its own citizens or of other persons who are under the protection of its laws."
43 The following principles of international law have been developed by English courts to avoid the risk of jurisdictional conflicts in respect of attempts to use court processes to obtain documents from international banks. I am of opinion that these principles are appropriate to apply in the present matter. I have taken the principles from obiter dicta in Société Eram Shipping Co Ltd v Cie Internationale de Navigation [2004] 1 AC 260 at 274-275 [22]-[23] per Lord Bingham of Cornhill, 286-287 [67] per Lord Hoffmann, with whom Lord Nicholls of Birkenhead at 277 [31], Lord Hobhouse of Woodborough at 287 [70] and Lord Millett at 299 [113], agreed. The principles are:
save in exceptional circumstances, an order should not be made by a court in the forum to compel a bank to produce books or records held by it in a branch or office outside the forum; and
a State (including courts exercising its judicial power) should refrain from demanding obedience by foreigners to its sovereign authority in respect of their conduct outside the jurisdiction.
44 Their Lordships approved the reasoning of Lord Denning MR, Shaw and Oliver LJJ in Reg. v Grossman (1981) 73 Cr App R 302 at 308-309 and Hoffmann J in Mackinnon v Donaldson, Lufkin and Jenrette Securities Corpn [1986] Ch 482. As Lord Bingham pointed out ([2004] 1 AC at 274 [22]), Hoffmann J in Mackinnon [1986] Ch at 493C-D identified a distinction between "personal jurisdiction, i.e. who can be brought before the court" and "subject matter jurisdiction, i.e. to what extent the court can claim to regulate the conduct of those persons". In that case, a plaintiff obtained an order against an American bank in an English proceeding and served it on the bank's London office requiring production of the bank's books and papers held in its New York head office. Hoffmann J said ([1986] Ch at 493G-H):
"In principle and on authority it seems to me that the court should not, save in exceptional circumstances, impose such a requirement upon a foreigner, and, in particular, upon a foreign bank. The principle is that a state should refrain from demanding obedience to its sovereign authority by foreigners in respect of their conduct outside the jurisdiction." (emphasis added)
45 His Lordship elaborated on the basis of the above principle of self-imposed limitation upon the sovereign authority of a State ([1986] Ch at 494 C-E) as follows:
"The need to exercise the court's jurisdiction with due regard to the sovereignty of others is particularly important in the case of banks. Banks are in a special position because their documents are concerned not only with their own business but with that of their customers. They will owe their customers a duty of confidence regulated by the law of the country where the account is kept. That duty is in some countries reinforced by criminal sanctions and sometimes by "blocking statutes" which specifically forbid the bank to provide information for the purpose of foreign legal proceedings: compare section 2 of our Protection of Trading Interests Act 1980. If every country where a bank happened to carry on business asserted a right to require that bank to produce documents relating to accounts kept in any other such country, banks would be in the unhappy position of being forced to submit to whichever sovereign was able to apply the greatest pressure." (emphasis added)
46 Hoffmann J had drawn on what Lord Denning MR said in Grossman 73 Cr App R at 307-308, namely, that while the English courts had jurisdiction to order the head office of a bank in London to produce books held in a branch in a foreign jurisdiction, the Isle of Man, that should not occur as a matter of discretion. Shaw LJ agreed and Oliver LJ, in a passage quoted by Hoffmann J, came to the same conclusion. And, pertinently, Hoffmann J said ([1986] Ch at 496D-E):
"The nature of banking business is such that if an English court invokes its jurisdiction even over an English bank in respect of an account at a branch abroad, there is a strong likelihood of conflict with the bank's duties to its customer under the local law. It is therefore not surprising that any bank, whether English or foreign, should as a general rule be entitled to the protection of an order of the foreign court before it is required to disclose documents kept at a branch or head office abroad."
47 I do not consider that the principles identified by their Lordships are affected by the circumstance that in those cases each of the banks was served as a non-party with a subpoena: see too Bank of Valletta 164 ALR at 59 [55].
