Before HOUGH, MANTON, and HAND, Circuit Judges.
HOUGH, Circuit Judge (after stating the facts as above).
There are several matters discussed at bar as to which discussion in this court may cease; we have expressed views which will remain in force until corrected by higher authority.
War between the United States and Germany ceased on July 2, 1921. Re Miller (C. C. A.) 281 F. 764; c. f. Swiss National Ins. Co. v. Miller, 266 U. S. 42, 45 S. Ct. 213, Feb. 2, 1925. Undoubtedly commercial relations were more or less re-established for approximately two years before that date, but that fact does not affect the material point that until July 2, 1921, a German was an alien enemy.
The date at which exchange is to be computed we have covered in Guiness v. Miller (C. C. A.) 299 F. 538, and sufficiently assigned reasons for our holding.
That the provisions of the Versailles Treaty do not affect nor relate to claims like that against the Deutsche Bank, we have also held in the Guiness Case, supra.
It is fundamental in both these suits to ascertain and declare the legal relation between plaintiffs and the defendant banks. It was admittedly that of depositor and banker, and there is no evidence that the nature of that common relation is not the same under German, Austrian, and American law.
It is therefore so plain as to need no citation in support that the relation of parties was merely that of debtor and creditor, the debt due on demand, and therefore not due until demand was made; and a demand is "a requisition or request to do a particular thing specified under a claim of right on the part of the person requesting." 3 Bouv. Law Dict. p. 2904.
It is useful next to inquire by the law of what country the mutual rights and privileges of the parties are to be determined. We have no doubt that by specific agreement the duties and obligations of the banks were to be determined by German and Austrian law, respectively. But, even without such agreement, since each bank had in effect made a contract to pay on demand at its own banking house, the same result is reached by applying the familiar rule of the law of the place where the contract is to be performed; i. e. Germany or Austria, as the case might be. London Assurance v. Companhia, 167 U. S. 149, 17 S. Ct. 785, 42 L. Ed. 113.
The above holding is made in both of these suits, though, as will appear, it is not from our standpoint material in respect of the Deutsche Bank, but it does greatly affect the claim against the Wiener Bank.
The question which most practically and very vitally affects these suits, and probably many others, may be thus put: What did the banks own plaintiffs? In answer we think it plain that they did not owe a certain number of units of any fixed value, nor could their debts be expressed in any universal currency; they owed only certain quantities of the thing called money within that political subdivision of the world in which the bank existed and to the laws of which it was subject. Therefore neither of these banks ever owed the plaintiffs any dollars. The only method of describing their debts is to speak of so many marks or kronen, which, like dollars, are merely legal and financial entities varying in exchange or purchasing power for reasons with which no court has any concern and over which it has no power or authority.
Therefore all that any American court can do is to translate a demand for marks or kronen into the dollars with which alone can we deal; and we must make that translation according to the facts as proven at a time fixed by law, and what that time is we have declared in the Guiness Case, supra.
Since, therefore, there can be no breach of contracts such as those at bar until a demand and refusal, and no assessment of damages in dollars until such demand, the question of fact is acute: When did plaintiffs make a demand upon these banks or either of them?
We may premise this inquiry by stating our agreement with the lower court in rejecting plaintiff's contention that their rights were created by the declaration of war on April 6, 1917; i. e. that such declaration was equivalent to a demand and refusal. We feel assured that the declaration had no such effect. Of course a declaration of war could do no more than the war itself, and that war does not affect the relations of parties to an executed contract, but merely suspends the remedies available thereunder, was fully held in Hanger v. Abbott, 6 Wall. 532, 18 L. Ed. 939.
*446 It is indeed obvious that, if the results of the declaration of April 6, 1917, were what plaintiffs claim, section 8 of the Trading with the Enemy Act (Comp. St. 1918, Comp. St. Ann. Supp. 1919, § 3115½dd) is quite superfluous, for that statute creates a method of making a demand which admittedly these plaintiffs complied with, and no reason for such a proceeding can be found if the declaration was in and of itself a demand by every American creditor upon every alien enemy debtor.
On this point of demand the evidence compels us to disagree with the court below. Passing the point that no demand was pleaded other than those of December 15, 1921, on the Custodian, it is argued that plaintiffs did in legal effect make several earlier demands, viz.: In March, 1919, by filing documents with the Custodian, and in August, 1919, by an interchange of letters and telegrams with both banks.
It would serve no useful purpose to recite the lengthy statutory demands of March, 1919; suffice it to say that we are convinced that all these documents related to the property of customers or clients of Zimmerman & Forshay which had either been impounded by the German authorities or lost track of in the fog of silence which had enveloped the Austrian bank. It is impossible to find in these documents any evidence of a demand for plaintiffs' own deposit account.
We are confirmed in this result by observing that as to each bank account, as soon as commercial relations were re-established, plaintiffs expressed the desire to go on with prewar business and maintain their old deposit accounts, and these desires were expressed after March, 1919.
Again in August, 1919, plaintiffs sent to each bank telegrams substantially as follows: "Regarding our old balance will you consent that Alien Property Custodian pay out of your firm funds in his custody equivalent in dollars at March 15, 1917, rate? * * * If you agree, wire us to that effect, and we will send you necessary papers to be filled out and signed by you. This will obviate lawsuit which we otherwise will be compelled to institute."
This was not a demand for plaintiffs' deposit accounts. It certainly, as was remarked by the court below, lacks some of the elements of a demand. We think it lacks too many to be a demand at all. What plaintiffs were entitled to were marks or kronen payable in Germany or Austria; what they asked for was the defendants' co-operation in their getting a certain number of dollars out of the Alien Property Custodian.
In the case, therefore, of the Deutsche Bank (and here the cases of the two banks diverge) we are constrained to the conclusion that the only demand for this deposit account was the one pleaded in the bill, i. e., of December, 1921; so that plaintiffs can recover only the number of marks sued for and agreed upon at the rate of exchange of the date of demand, i. e., said December.
But, in respect of the Deutsche Bank, that concern had a deposit account with plaintiffs in like manner, and for the same purposes that plaintiffs had their deposit account in Germany. By amendment duly allowed, Deutsche Bank had pleaded this deposit as a set-off, and also similarly pleaded indebtednesses arising on new and wholly different banking transactions be-between itself and Zimmerman & Forshay, amounting to a considerable sum of money.
The court below allowed as an offset Deutsche Bank's bank balance with Zimmerman & Forshay as the same existed on April 6, 1917; but refused to permit any further offsets though arising out of banking transactions of a somewhat similar nature. In this we think error was committed. At law a set-off is known to be of comparatively recent statutory origin, but law derived its whole doctrine from equity, and this suit is governed by equitable principles. One of those principles is to ascertain what was due by one party to the other at the commencement of the suit, so that, generally speaking, one party should be prevented from asserting offsets arising after suit begun. Holden v. Gilbert, 7 Paige, 208; Pate v. Gray, Fed. Cas. No. 10,794a.
The record does not inform us how much of defendant's offsets were due and payable on or before February 28, 1922. Therefore in the case of the Deutsche Bank the decree must be reversed and the cause remanded, with directions to strike an account as of February 28, 1922, between the parties, and to grant plaintiffs' recovery for whatever excess there may be in its favor; plaintiffs' claim being, of course, liquidated at the rate of exchange of December, 1921.
In the case of the Wiener Bank, the foregoing recital of facts shows that no demand had been made prior to April 1, 1920. But there had arisen a difference of opinion as to the rate at which plaintiffs' old account would be available for exchange. Therefore, as we have held that these parties were subject to the operation of Austrian law, payment into court of all the kronen due *447 was a complete extinguishment of plaintiffs' demand on the Wiener Bank.
Let the decree in that case be reversed, and the cause remanded, with directions to dismiss the bill. The Wiener and Deutsche Banks will recover the costs of this court. No other costs here. The costs of the District Court are left to the discretion of that tribunal.
