Every person of Swiss nationality who has reached the age of 18 has the right to vote at federal level, i.e. they can participate in the election of the National Council, as well as in federal popular votes, but can also launch and sign referendums and initiatives at federal level. However, persons lacking legal capacity are ineligible to vote.
Please note: Voting rights for cantonal elections (including the election to the Council of States) are regulated at cantonal level and can vary from canton to canton.
