(1) The name of the party must be clearly distinguishable from that of any existing party; this shall also apply to acronyms. In canvassing and the electoral procedure, only the registered name or acronym may be used; supplementary designations may be omitted.
(2) Regional branches shall bear the name of the party and the designation of their organizational status. This supplementary designation in connection with the name of regional branches is only permissible if it is placed after the name of the party. The supplementary designation may be omitted in general advertising and canvassing.
(3) Regional branches which withdraw from a party shall lose the right to continue to use the party's name. A newly chosen name may not merely consist of an addendum to the previous name. The same shall apply to acronyms.
