Some states impose restrictions, however, as to the legal nature of the acts that may be submitted to referendum. In the Czech Republic, municipal regulations cannot be submitted to referendum; in Malta, on the other hand, they are the only possible subject-matter of a referendum; in Ireland, this instrument is confined to draft financial schemes. In Switzerland, a wide range of acts are submitted to referendum: except for referendums on cantonal constitutions, which are mandatory under the federal constitution, these acts – at both cantonal and local level – are specified by cantonal law; at cantonal level, for instance, there is usually provision for referendums on laws and on certain items of expenditure (financial referendums). In Austria too, the law of the federate entities (Länder) specifies the acts that can be submitted to referendum: at the level of the Länder, these are usually bills passed by the Landtag (regional Parliament); at local level, municipal council decisions.
