Duckionary's constitution is the country's most important legal document and governs the basic structure of the state, its relations with other nations and constituent states, and the rights and duties of its citizens. It represents the supreme norm to which all state power is bound and which limits its actions. Constituent power emanates from the archduke and takes precedence over all other statutory provisions.
The actions of the state organs are bound by the provisions of the constitution and their observance is monitored by a special constitutional court. This can not only declare laws to be unconstitutional, but also, if necessary, declare constitutional amendments to be ineffective constitutional law. However, it is either not possible at all or only to a limited extent for review by these courts, since the constitution itself represents the measure for assessing the legality of state action. The constitution can only be changed under difficult conditions and therefore requires a separate constitutional legislature to change it.
