"Swiss bank secrecy does not protect private banking information; the protections afforded under Swiss law are similar to confidentiality protections between doctors and patients or lawyers and their clients. The Swiss government views the right to privacy as a fundamental principle that should be protected by all democratic countries. While secrecy is protected, in practice all bank accounts are linked to an identified individual, and a prosecutor or judge may issue a "lifting order" in order to grant law enforcement access to information relevant to a criminal investigation."
