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.
Postal voting
A form of postal voting was introduced in Western Australia in 1877, followed by an improved method in South Australia in 1890. On the other hand, concerns about postal voting have been raised as to whether it complies with the requirements of a secret ballot, in that people cast their vote outside the security of a polling station, and whether voters can cast their vote privately free from another person's coercion. There have been cases of electoral fraud with postal votes in the United Kingdom (including in Birmingham at the 2004 European and local government elections in the UK).
