A constitutional referendum was held in Switzerland on 31 October 1880 aiming at a complete overhaul of the constitution.[1] The constitutional amendments were rejected by 68.2% of voters and a majority of cantons.[1]
In order to pass, any amendments to the constitution needed 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]
