The rule of unity of content is not imposed any more often in respect of local and regional referendums than for national referendums. It applies, for instance, in Armenia, Bulgaria, Italy, Portugal, Switzerland and Hungary, where, as is the case in national referendums, parts of a question must not be contradictory, their relationship with one another must be clear and they must flow from one another or be linked by their content. In Austria, the approach adopted depends on the Land.
