Estonia was the only EU country to allow Internet voting for the European Parliament elections, last June 7. Over than 58 000 voters used e-voting, which is 15% of all the people who voted. The e-voting system has been in Estonia under development since 2002 with the final pilot held at the end of 2004. It has been several times presented at the World eDemocracy Forum. In 2005 the system was used for the first time for local government council elections. In 2007, for the first time in the world it was possible in Estonia to vote online also in parliamentary elections.
At that time, a total of 30,275 out of 940,000 registered voters used that opportunity and cast their ballots via the Internet.
Internet voting in Estonia is presented a supplement, not to replace the traditional methods of voting. The idea is to give voters the possibility to vote from the location of their choice (home or office), without the necessity of going to the polling station. Therefore remote voting is used.
