The
Bank of Tokyo was a Japanese Bank operating in
London and a wholly owned subsidiary of the Bank of Tokyo Trust Co, a New York corporation. Mr Karoon, an Iranian employee of the Iranian Maritime Co had personal accounts with both banks. He left Iran and transferred his money from the New York to the London bank. In February 1980 the London bank was notified that Mr Karoon was sentenced to prison by the Iranian government, and requested his assets be sent to the Iranian government. Mr Karoon asked the bank to transfer his accounts to another bank. The bank, unsure of what to do, applied for an
interpleader summons and the money was eventually paid into court. Mr Karoon sued the New York bank claiming breach of the duty of confidentiality in disclosing information to the London bank, and the London bank sought to restrain him taking proceedings in the American courts. ==Judgment==
