Election silence, pre-election silence, electoral silence, or campaign silence is a ban on political campaigning prior to a presidential or general election. Under this rule, in some jurisdictions, such as Slovenia, any mention of the candidate on the day of election was prohibited. Some jurisdictions have declared that, legally, election silence is in violation of law regarding freedom of speech. It is however used in some of the world's democracies "in order to balance out the campaigning and maintain a free voting environment".
An election silence operates in some countries to allow a period for voters to reflect on events before casting their votes.[need quotation to verify] During this period no active campaigning by the candidates is allowed. Often polling is also banned. The silence is generally legally enforced, though in some countries it is just a "gentlemen's agreement" between leading parties.
The U.S. Supreme Court ruled in Burson v. Freeman (1992) that campaigning can only be limited on election day in a small area around the polling station. Any broader ban on speech would be unconstitutional. In Bulgaria, the constitutional court ruled in 2009 that both electoral silence and ban on opinion polls before the election day represented a violation of freedom of speech. The Constitutional Court of Hungary ruled in 2007 that a ban on opinion polls was unconstitutional, but upheld electoral silence. The Constitutional Court of Slovenia ruled in 2011 that a ban on opinion polls was unconstitutional. Per Section 329 of the Canada Elections Act, Canada formerly banned the distribution of election results in regions of the country where polls have not yet closed, so results from ridings in the Eastern and Atlantic provinces would not influence results in the west. This ban, although upheld by the Supreme Court, was repealed in 2012.
In Slovenia until 2016 any mention of the candidate on the day of election was prohibited. Those who published positive or critical statements about parties or candidates on social media, online forums, or stated them for example in restaurants, were prosecuted and fined. For over two decades, media and voters refrained from talking about politics on the day before the elections and on election day. In 2016, the Supreme Court ruled that "not every opinion is propaganda", published a new definition of the term 'propaganda' and reverted a lower court judgement, which convicted a person who published "Great interview! Worth reading!" on Facebook.
