Various voting systems have been used in the history of the contest to determine the placing of the competing songs. The current system has been in place since 2023, which works on the basis of
positional voting. Each country awards two sets of points: one set is based on the votes of each professional jury appointed by each participating broadcaster, consisting of five music professionals from that country; and a second set is based on the views of the general public in the competing countries conducted through
telephone and SMS voting or via voting conducted through the official Eurovision
app. Each set of points consists of 1–8, 10, and 12 points to the jury and public's 10 favourite songs, with the most preferred song receiving 12 points. In the semi-finals, each country awards one set of points based on the votes cast by that country's viewing public, while in the final, each country awards two sets of points, with one set awarded each by the viewers and the professional jury. National juries and the public in each country are not allowed to vote for their own country, a rule first introduced in 1957. Historically, each country's points were determined by a jury, which has at times consisted of members of the public, music professionals, or both in combination. The was the first to make televoting mandatory for all competing countries, however each country was obligated to provide a "backup jury", which would be used in case of voting failure, or if the number of votes registered did not pass a set threshold to be considered valid. A jury was reintroduced for the final of the , with each country's points comprising both the votes of the jury and public in an equal split. This mix of jury and public voting was expanded into the semi-finals from 2010, and was used until 2023, when full public voting was reintroduced to determine the results of the semi-finals. The mix of jury and public voting continues to be used in the final. Prior to 1994 the announcements were made through
telephone lines from the countries of origin, with the audio piped through into the auditorium for the audience to hear and over the television transmission; the saw the introduction of
satellite links for the voting, which has allowed the spokespersons to be seen visually by the audience and television spectators. The votes from each country are tallied via a
scoreboard, which typically shows the total number of points each country has so far received, as well as the points being given out by the country currently being called upon by the presenter(s). The scoreboard was first introduced in 1957; voting at the first contest was held behind closed doors, but taking inspiration from the UK's
Festival of British Popular Songs which featured voting by regional juries, the EBU decided to incorporate this idea into its own contest. This scoreboard was historically situated physically to the side of the stage and was updated manually as each country gave their votes; a
graphical representation of this scoreboard was first introduced at the , which in recent contests is able to sort itself to place the country with the most votes at the top. Historically, each country's spokesperson would announce sequentially the number of points being given to a specific country, which would then be repeated by the contest's presenter(s) in both English and French. With the increase in the number of competing countries, and therefore the number of countries voting in the final, the voting sequence soon became a lengthy process. From 2006, to save time, only each country's 8, 10 and 12 points were announced by their spokesperson, with points 1–7 displayed on-screen and then automatically added to the scoreboard. Since the introduction of the new voting system in 2016, the spokespersons now announce only their country's 12 points, with their 8 and 10 points now also being shown and added automatically. With the introduction of semi-finals in 2004, a new system to determine the order of voting was required to account for the countries which failed to qualify for the final: in 2004, the countries were called upon in alphabetical order according to their
two-letter ISO country codes; and in 2005, the votes of the non-qualifying semi-finalists were announced first, in the order in which they performed in the semi-final, followed by the finalist countries in the order in which they performed in the final. From 2006 to 2010, similar to 1974, a separate draw was held to determine the voting order; this draw was scrapped in 2011, and a new logarithmic system was implemented which used the jury votes submitted following the "jury final" dress rehearsal in an attempt to ensure the winner did not become apparent early on in the voting sequence, and subsequently to create a more suspenseful and exciting experience for the viewers. Since 2016, the voting presentation begins with each country's spokespersons being called upon in turn to announce the points of their country's professional jury. Once the jury points from all countries have been announced, the contest's presenter(s) will then announce the total public points received for each finalist, with the votes for each country being consolidated and announced as a single value. As there was no rule in place to break the tie, all four were declared joint winners. This result led to complaints from a number of other competing broadcasters, and several refused to take part in in protest. To date, on only one occasion since 1969 has there been a tie for first place: in , the entries from and had received 146 points each at the end of the voting. The tie-breaking rule in place at the time specified that the country which had received the most sets of 12 points would be declared the winner; if there was still a tie, then the 10 points received, followed by 8 points, etc. would be used to break the tie. Both France and Sweden had received four sets of 12 points, however as Sweden had received more individual 10 points than France, Sweden's
Carola was declared the winner.
Validation and observation A number of steps have been established to ensure that a valid voting result is obtained and that transparency in the vote and results is observed. Each country's professional jury, as well as individual jury members, must meet a set criteria to be eligible, regarding professional background, and diversity in gender and age. A set criteria against which the competing entries should be evaluated is published by the EBU, and all jury members pledge in writing that they will use these criteria when ranking the entries, as well as stating that they are not connected to any of the contestants in any way that could influence their decision. Additionally, jury members may only sit on a jury once every three years. Each jury member votes independently of the other members of the jury, and no discussion or deliberation about the vote between members is permitted. Since 2004, the televoting in each country has been overseen by the contest's official voting partner, the Germany-based Once (formerly Digame). This company gathers all televotes and, since 2009, jury votes in all countries, which are then processed by the company's pan-European response platform, based out of its voting control centre in
Cologne. This system ensures that all votes are counted in accordance with the rules, and that any attempts to unfairly influence the vote are detected and mitigated. == Broadcasting ==
