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.
Representative democracy in Singapore
Voting in Singapore is compulsory. Any citizen above 21 years of age who is not disqualified by the factors in section 6 of the Parliamentary Elections Act is required to vote in person. There is no constitutional provision stipulating any qualifications for voters, and as the Act is an ordinary piece of legislation the disqualifying factors may be changed by a simple majority (more than 50%) of votes in Parliament.
