From https://en.wikipedia.org/wiki/Direct_democracy :
"Switzerland is a rare example of a country with instruments of direct democracy (at the levels of the municipalities, cantons, and federal state). Citizens have more power than in a representative democracy. At the federal level, citizens can propose changes to the constitution (federal popular initiative) or ask for a referendum to be held on any law voted by the parliament.[16] Swiss citizens vote regularly on any kind of issue on every political level, such as financial approvals of a school house or the building of a new street, or the change of the policy regarding sexual work, or on constitutional changes, or on the foreign policy of Switzerland, four times a year"
