Election silence, pre-election silence, electoral silence, or campaign silence is a ban on political campaigning prior to a presidential or general election. 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. 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 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.
The most common phrase used in English is "blackout period".
