Five referendums were held in Switzerland during 1929.[1] The first three were held on 3 March on the issues of grain supply (a proposal and counter-proposal) and a federal law on tariffs.[1] The counter-proposal to the grain supply question and the tariffs law were both approved.[1] The fourth and fifth referendums were held on 12 May on popular initiatives on road traffic and banning spirits.[1] Both were rejected by voters.[1]
The grain supply, road traffic and spirits referendums were popular initiatives,[1] which required 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] The tariffs law question was an optional referendum,[1] requiring only a majority of voters in favour.[2]
