UBS Group AG's attempt to clarify a $1.25 billion legal settlement regarding claims from Holocaust victims was thwarted by US District Judge Edward Korman. UBS argued that the 1999 accord, which involved several Swiss banks, shielded it from any new financial claims related to Nazi-linked accounts. The bank is currently in a federal court dispute in Brooklyn, New York, with the Simon Wiesenthal Center, an organization dedicated to pursuing justice for Nazi victims. UBS's attorney, David Burns, emphasized the need for clarification to prevent the Wiesenthal Center from pursuing additional claims, which could expose the bank to liabilities potentially worth billions of dollars. However, Judge Korman ruled that he could not provide an advisory opinion without an active lawsuit before him. UBS acknowledged the ongoing controversy and reiterated that the settlement aimed to achieve a definitive resolution to the claims against it. The case is known as Friedman v. UBS, 96-cv-04849, in the US District Court for the Eastern District of New York.
