Germany - 2004 Party Law

Title Article 7 Organization
Section II Internal Organization
Article

7

(1) Parties shall be organized in regional branches. The size and scope of the regional branches shall be laid down in the statutes. The regional structure of the party must be developed to a sufficient degree to enable individual members to participate on an appropriate scale in the formation of the political will of the party. Any party whose organization is confined to the territory of a city-state does not need to establish regional branches; it constitutes a party within the meaning of the present law. It is permissible for several regional branches to merge for organizational purposes if this does not substantially impair the branch structure of the party organization.
(2) Where there are no Land branches in a party, the provisions set out in the present law for Land branches shall apply for the next level of regional branch below that of the party itself.
