ZURICH, (Reuters) – A Swiss court rejected the appeal of an Arab businessman seeking to stop Japanese prosecutors getting details from bank accounts in order to investigate Carlos Ghosn. The verdict was released Friday.

Ghosn is the architect of Renault-Nissan’s auto alliance. He has faced multiple investigations since he fled to Lebanon in late 2019 from Japan.

Ghosn was the chairman of Nissan (OTC-:) as well as Mitsubishi. He also served in chief executive of Renault (PA:), when he was detained in Japan in 2018. He was accused of using company funds to pay personal expenses and under-reporting salary. He denied any wrongdoing.

Japanese prosecutors requested legal help from Switzerland in order to obtain documents from Ghosn’s bank accounts. Zurich prosecutors consented last year to give them over. The appeal was made by an unidentified associate which the Federal Criminal Court dismissed on Friday.

According to the verdict, “The Japanese authorities provide concrete evidence that funds of allegedly illegal origin might have been deposited into two accounts in the complainant’s name” at two banks unidentified.

Although the appellant was not named in the verdict, it did not identify him as a businessman. Zurich authorities identified him only to be an Arab businessman. The accounts at question were held in two Zurich-based bank accounts they didn’t identify.
