[Federal guarantee of Land constitutions and of local self-government]

(1) The constitutional order in the Länder must conform to the principles of a republican, democratic, and social state governed by the rule of law, within the meaning of this Basic Law. In each Land, county, and municipality the people shall be represented by a body chosen in general, direct, free, equal, and secret elections. In county and municipal elections, persons who possess citizenship in any member state of the European Community are also eligible to vote and to be elected in accord with European Community law. In municipalities a local assembly may take the place of an elected body.

(2) Municipalities must be guaranteed the right to regulate all local affairs on their own responsibility, within the limits prescribed by the laws. Within the limits of their functions designated by a law, associations of municipalities shall also have the right of self-government according to the laws. The guarantee of self-government shall extend to the bases of financial autonomy; these bases shall include the right of municipalities to a source of tax revenues based upon economic ability and the right to establish the rates at which these sources shall be taxed.
(3) The Federation shall guarantee that the constitutional order of the Länder conforms to the basic rights and to the provisions of paragraphs (1) and (2) of this Article.
