Compulsory voting
Compulsory voting is increasingly resented by citizens in some countries such as Brazil, the largest country where compulsory voting is enforced: at the last presidential election in 2014, some 30 million voters, about 21% of registered voters, did not vote, despite the fact that Brazil has some of the most severe penalties enforced against non voters.

A counter argument to opponents of compulsory voting is that in these systems the individual still has the practical ability to abstain at the polls by voting informally if they so choose, due to the secrecy of the ballot. A spoilt vote does not count towards any political party and effectively is the same as choosing not to vote under a non-compulsory voting system. However, Singer argues that even the appearance of voluntary participation is sufficient to create an obligation to obey the law.
