The clarity of the question is a crucial aspect of voters’ freedom to form an opinion. The question put to the vote must be clear and comprehensible; it must not be misleading; it must be unbiased, not suggesting any or a specific answer, particularly by mentioning the presumed consequences of approving or rejecting the proposal. Voters must be able to answer the questions asked solely by yes, no or a blank vote. An open question necessitating a more detailed answer must not be asked. Lastly, electors must be informed of the impact of their votes (effect of the referendum), and thus of the legal effects of the referendum (is it legally binding or consultative? does a positive outcome lead to the adoption or repeal of a measure, or is it just one stage in a longer procedure?) It is suitable that the questions follow a fixed format. Multiple-option questions can be envisaged (point I.3.1.c).
