The wrongful-termination lawsuit filed by George Schwyzer, former compliance officer at New York’s Fiduciary Trust International, against his old company has been dismissed, according to the bank, but the matter that allegedly prompted the complaint raises issues of whether private banks may be violating anti-money laundering laws. Citing industry sources, The New York Post reports that Schwyzer was axed after he expressed concern about an unaccounted-for $2 billion in an account in the name of one of the three wives of the Sultan of Brunei, Sultan Hassanal Boliah, reportedly the richest Muslim leader in the world. The USA Patriot Act requires banks to keep track of all cash coming from abroad, including how it is being used and who is using it. According to the Post, Fiduciary Trust asked a court to seal the records once Schwyzer sued, but not before the New York banking industry got a peek at the allegations. The sultan has not been linked to terrorism, for which the Patriot Act provisions were enacted. The Post says a congressional task will now review the account to see if it violated the Patriot Act.
