1903 Swiss referendums

Background

The referendums on tariffs and the federal criminal law were optional referendums, which required only a majority of the public vote. The referendum on the changes to National Council elections was popular initiative and the referendum on the constitutional amendment was a mandatory referendum, both of which required a double majority; a majority of the popular vote and majority of the cantons. The decision of each canton was based on the vote in that canton. Full cantons counted as one vote, whilst half cantons counted as half.
