Stefan Buck, former head of private banking at Bank Frey, wants to fight the charges of helping rich US clients avoid taxes. Reuters reports that he asked ‘for an unusual hearing in which a judge in New York would proceed with the bail application in his absence. In the filing, he said he sought a waiver that would allow him to return to Switzerland while the case is ongoing’.

A Swiss attorney who was charged alongside S.Buck, Edgar Paltzer, pleaded guilty in 2013 and has since been allowed to return to Switzerland and travel throughout Europe.
