"(a) In English law, the payment of the debt by the bank will give the bank a [sic] implied contractural [sic] or restitutionary right to recover the sum paid from the Judgment Debtor; (b) It is also a demand for payment by the Judgment Debtor, compliance with which even in the absence of an account in this country, entitles the bank to reimbursement; (c) There is therefore an English law liability created in favour of the bank against the Judgment Debtor; (d) This debt the bank is entitled to set against the credit balance pursuant to clause 1(I) of the terms and conditions ….."
"1. GENERAL (applicable to all accounts) i. The account holder agrees that the Institution's indebtedness to the account holder shall not exceed the net amount owing by the Institution to the account holder after deducting from any credit balance held by the Institution or providing for the aggregate of all the account holder's liabilities ….. whether such liabilities be actual, present, future, deferred, contingent, primary, collateral, several, joint or otherwise (together the "account holder's aggregate liabilities"). Without prejudice to the generality of the foregoing and in addition to any general lien, right of set-off or other right by way of security which the Institution may have on any account whatsoever, the account holder agrees that the Institution shall have the right, at its sole and absolute discretion and without notice to the account holder. to refuse to repay when demanded or when the same falls due any of the Institution's indebtedness to the account holder if and to the extent that the account holder's aggregate liabilities at the relevant time are equal to or exceed the Institution's indebtedness at that time. …"
"1.-(1) Where a person (in this order referred to as "the judgment creditor") has obtained a judgment or order for the payment by some other person (in this order referred to as "the judgment debtor") of a sum of money amounting in value to at least£50 , not being a judgment or order for the payment of money into court, and any other person within the jurisdiction (in this order referred to as "the garnishee") is indebted to the judgment debtor, the court may, subject to the provisions of this order and of any enactment, order the garnishee to pay the judgment creditor the amount of any debt due or accruing due to the judgment debtor from the garnishee, or so much thereof as is sufficient to satisfy that judgment or order and the costs of the garnishee proceedings. (2) An order under this rule shall in the first instance be an order to show cause, specifying the time and place for further consideration of the matter, and in the meantime attaching such debt as is mentioned in paragraph (1) or so much thereof as may be specified in the order, to answer the judgment or order mentioned in that paragraph and the costs of the garnishee proceedings. ….. 3.- (1) Unless the court otherwise directs, an order under rule 1 to show cause must be served – (a) on the garnishee personally, at least 15 days before the time appointed thereby for the further consideration of the matter; and (b) on the judgment debtor, at least 7 days after the order has been served on the garnishee and at least 7 days before the time appointed by the order for the further consideration of the matter. (2) Such an order shall bind in the hands of the garnishee as from the service of the order on him any debt specified in the order or so much thereof as may be so specified. ….. 8. Any payment made by a garnishee in compliance with an order absolute under this order, and any execution levied against him in pursuance of such an order, shall be a valid discharge of his liability to the judgment debtor to the extent of the amount paid or levied notwithstanding that the garnishee proceedings are subsequently set aside or the judgment or order from which they arose reversed."
"The Order deals with the case where "any person is indebted to the judgment debtor and is within the jurisdiction"
"…. as a matter of discretion, a garnishee order will not be made against such a person if it would not operate to discharge the garnishee in whole or pro tanto from his liability in respect of the debt. Such a situation can arise where the garnishee, although himself within the jurisdiction, is not indebted within the jurisdiction"
"(1) The underlying judgment by the English court in favour of the judgment debtor has been entered by a court which is, by generally accepted principles of international law, a court of competent jurisdiction. (2) The situs of the attached debt, owing by the garnishee to the judgment debtor, is England. (3) Payment of the attached debt by the garnishee pursuant to the garnishee order absolute has the effect of discharging that debt."
"But the question arises whether cases of this kind are to be solved by exclusive reference to this assumption. The point may arise in two ways. First, let it be supposed that one or other of the two criteria is not fulfilled, i.e. that the English court is not, by accepted principles of international law, competent with regard to the underlying judgment against the judgment debtor, or alternatively that the situs of the attached debt is not England. Will the English court in such circumstances automatically decline to make the garnishee order absolute, on the ground that there is a real risk that a foreign court may, despite payment by the garnishee pursuant to such a garnishee order absolute, nevertheless enforce the attached debt against the garnishee overseas? Second, let it be supposed that both criteria are fulfilled. Will an English court, in such circumstances, make a garnishee order absolute in accordance with the assumption, and exclude as irrelevant and inadmissible any evidence that a foreign court will nevertheless not recognise payment under the English order as effective to discharge the attached debt?"
"I have mentioned that there are these two questions, for the sake of completeness; but I doubt whether the answer to the first question has much bearing on the answer to the second question with which your Lordships' House is here concerned. In fact, Martin v Nadel indicates that, in that case at least, there was consideration whether the courts in Berlin (the situs of the attached debt) would or would not recognise a payment under a garnishee order absolute in England as effective to discharge the attached debt. It was taken to be the fact that they would not, though this was by admission. In any event, the court was there concerned with a situation where the assumption was not available to provide a solution with reference to the position in this country. All that can be said of the case is that the question whether there was a real risk of the garnishee being compelled to pay twice over was being answered by reference to the factual situation."
"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."
"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. ….. 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."
"If the burden lies on the Garnishee, it has discharged it by reliance on the law of Hong Kong. The Judgment Creditor's argument by reference to restitutionary principles is misconceived. If the burden lies on the Judgment Creditor it has failed to discharge it."
