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.
Conscience vote
In most countries, conscience votes are quite rare and are often about issues which are very contentious, or a matter on which the members of any single party differ in their opinions; thus making it difficult for parties to formulate official policies. Usually, a conscience vote will be about religious, moral or ethical issues rather than about administrative or financial ones. Matters such as the prohibition of alcohol, homosexuality law reform and the legality of prostitution are often subject to conscience votes.
