Some countries have rules stipulating that the authorities must not only put the text at the disposal of citizens, but also provide additional objective information. In the Netherlands, a summary of the text is sent to voters. Other states arrange for an explanatory note or other information to be made available. In Switzerland, the text put to the vote is sent to voters together with an explanatory note from the Federal Council (Government), which must set out the various points of view in a balanced manner. In France, even if this is not prescribed by law, in practice the authorities have to supply objective information, by providing voters with the text and an explanatory note. The draft note is checked by the Constitutional Council, as a matter of course. In Finland, an objective explanatory note was sent to voters for the referendum on the country’s accession to the European Union in 1994 (a special law is passed for each referendum). Such a note is drawn up in Ireland if the two houses of Parliament make provision for this and it must be neutral. In Portugal, all the authorities are required to ensure the strictest impartiality, while in Latvia the Central Electoral Commission must provide citizens with neutral information, especially on the draft put to the vote.
