Liechtenstein is therefore not a constitutional monarchy in the conventional sense. Rather, it is a worldwide unique mixed system between direct democracy and parliamentary-constitutional hereditary monarchy. In addition to parliament, the people and the Reigning Prince have their own relevant rights of control and co-determination, which are not subject to the influence of the parties; the municipalities may also introduce their own legislative initiatives. In order to counter the danger of unrestricted majority rule through direct democracy, the Liechtenstein system has incorporated two safety valves: on the one hand, the prince's right of veto even against the results of referendums, and on the other, the right of secession of each individual community.
