Deutsche Bank Filiale Nurnberg v. Humphrey

Background

Humphrey, an American citizen, deposited money payable on demand in a German bank and asked for it around June 12, 1915. The bank did not pay. Humphrey sued in the United States on July 9, 1921 to attach money the government had seized from the bank and held in the U.S. Treasury under wartime controls. The debt was denominated in German marks and the lower courts used the exchange rate on the 1915 demand date to convert marks into dollars.

Reasoning

The Court’s majority, led by Justice Holmes, asked when a U.S. court should measure a foreign-currency debt in dollars. It said the suit enforces an obligation that exists under German law at the time the lawsuit is brought here. Because the obligation was fixed in marks only, the Court held the dollar conversion should reflect the obligation as it stood when the suit was filed, not at the earlier demand date. The majority reversed the lower court’s decree for that reason.

Real world impact

The ruling lowers recoveries for creditors when a foreign currency falls in value after a demand but before a suit is brought. It affects people and businesses who sue in U.S. courts to collect debts payable abroad because their dollar awards will be based on the obligation’s value when the lawsuit starts. The decision emphasizes applying the foreign law’s terms, not adding extra protection for currency fluctuations.

Dissents or concurrances

Justice Sutherland dissented. He argued conversion should start at the date of the wrong or nonpayment, saying that fixes the loss and avoids result variability from delays in bringing or finishing litigation.
