Electoral system for the president

Federal Constitutional Law (Bundes-Verfassungsgesetz)

Art. 60 (1) The Federal President is elected by the federal people on the basis of equal, direct, personal, free and secret suffrage by men and women having suffrage to the National Council. If there is only one candidate, the election shall take place by way of referendum. Article 26 para 5 to 8 is to be applied accordingly. 

(2) The candidate who polls more than half of all valid votes has been elected. If no such majority results, a second ballot takes place. Votes in this can validly be cast only for one of the two candidates who have polled the most votes in the first ballot.
