Compulsory voting
Compulsory voting is an effect of laws which require eligible citizens to register and vote in elections, and may impose penalties on those who fail to do so. , 22 countries provide for compulsory voting, and 11 democracies — about 5% of all United Nations members — enforce it.
Right of foreigners to vote
The 1992 Maastricht Treaty imposed reciprocity inside the European Union concerning voting rights in local elections; this already existed for the European elections. In several European states, the public debate on the right of foreigners to vote was therefore renewed, as some foreign residents had the right to vote (European foreign residents) while others, non-Europeans, did not. As a result of this debate, Luxembourg, Lithuania, Slovenia and Belgium extended the right to vote, in different manners, to all foreign residents (which was already the case in Sweden, Denmark, Finland and Netherlands).
