1949 Swiss referendums

Background

The referendum on revising the constitution was a mandatory referendum. Together with the popular initiative, 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 referendums on federal laws on tuberculosis and civil servants were both optional referendums, which required only a simple majority of votes in favour.
