Three referendums were held in Switzerland during 1908.[1] The first two were held on 5 July on amending the federal trade law and on banning absinthe.[1] Both were approved by a majority of voters and cantons.[1] The third was held on 25 October on adding article 24bis to the constitution, concerning hydroelectricity and electricity.[1] It was also approved by a majority of voters and cantons.[1]
The referendum on banning Absinthe was a popular initiative, whilst the referendums on the trade law and amending the constitution were mandatory referendums.[1] Both types required a double majority; a majority of the popular vote and majority of the cantons.[2] The decision of each canton was based on the vote in that canton.[2] Full cantons counted as one vote, whilst half cantons counted as half.[2]
