Article 6 limits to one “the number of issues to be submitted” to referendum (6.3) and prohibits holding referenda “on the same day” as any political elections (6.2). These rules are in theory quite logical, but it is not clear at all that they should be fixed as legal – absolute – rules, because it may perfectly happen – and in practice, it is quite common in comparative terms- to hold a referendum on the same election day, or with other different referendums. Of course, this possibility is much easier if the whole referendum organisation (voter lists, polling stations and commissions) is common with the electoral one.
