Originally, only some of the Bundesländer (federated
states of Germany) had provisions for a general binding referendum (
Volksentscheid, "people's decision") on popular
initiatives (
Volksbegehren, "people's request"), with Hesse and Bavaria also having a mandatory binding referendum on changes to the state constitution. Over the years all states have changed their constitutions to allow various types of statewide and municipal referendums. In all states, there is now a general right for referendums on statewide popular initiatives, which was used in Hamburg to push the state government to pass a law on a facultative binding state referendum in 2007. Most states have a form of non-binding ballot question (
Volksbefragung, "people's inquiry") which has rarely been used - the most important of these had been the
1955 Saar Statute referendum. General forms of direct democracy were introduced in the communities with facultative ballot questions (
Bürgerbefragung, "citizens' inquiry") and public initiatives (
Bürgerbegehren, "citizens' request") which are both non-binding. In some areas, this has been expanded into a binding referendum type (
Bürgerentscheid, "citizens' decision"). == Initiative quorum ==
