Swiss referendums, 1882 Wikipedia
The referendums on epidemics and the constitution were optional referendums, which meant that only a majority of the public vote was required for the proposals to be approved. The referendum on copyright law was a mandatory referendum, which required both a majority of voters and cantons to approve the proposals.
