1947 Swiss referendums

Background

The May referendum, which was a popular initiative, and the July referendum on amending the constitution, which was a mandatory referendum, both 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. The July referendum on the federal law on aged and bereavement insurance was an optional referendum, which required only a simple majority of votes in favour.
