Freedom to vote presupposes that “the question submitted to the electorate must be clear (not obscure or ambiguous); it must not be misleading; it must not suggest an answer; electors must be informed of the consequences of the referendum; voters must answer the questions asked by yes, no or a blank vote”. A number of national legal systems explicitly uphold these rules, especially the requirement that the question be clear. In Albania, questions of principle (particularly important questions) submitted to the electorate must be clear, complete and unequivocal; in Armenia, the question must be straightforward; in Hungary, devoid of ambiguity; in Portugal, questions must be formulated in an “objective, clear and precise manner”, and may not contain any suggestion or preliminary considerations; in France three conditions are attached: fairness, clarity and absence of ambiguity. The requirement for clarity relates to the rules providing that the voter should be able to reply yes or no (Austria, Croatia, Greece, Malta, “the former Yugoslav Republic of Macedonia”) or to vote on a specificallyworded text (Ireland). The requirement that the question be clear and non-leading is also upheld in Bulgaria, Italy, Poland, Portugal and Switzerland. Elsewhere it should apply in pursuance of the principle of freedom to vote.
