According to statements to the media by a Federal Chancellory official, in none of the few cases of accusations against a Federal Councillor has the permission to prosecute ever been granted. Such cases usually involved statements considered offensive by members of the public. However, one unnamed Councillor involved in a traffic accident immediately prior to his date of resignation was reported to have voluntarily waived his immunity, and Councillor Elisabeth Kopp decided to resign upon facing an inquiry over allegations of secrecy violations.
