The appeal body’s minimum powers are specified, insofar as respect for free suffrage and the results of the ballot are expressly mentioned. Other aspects specific to referendums and popular initiatives should be subject to judicial review, at least in the last instance: the completion of popular initiatives and requests for referendums from a section of the electorate, along with the procedural and, where applicable, substantive validity of texts submitted to a referendum. The review of validity, whether obligatory or optional, should take place before the text is put to the vote: this will avoid the voters having to express their views – in vain – on a text that is subsequently ruled invalid because it is contrary to superior law (substantive invalidity) or the content of which breaches the requirements for procedural validity (point II.4.3.d, cf. points III.1-2).
