Compulsory voting
Countries that have compulsory voting by law but do not enforce it:Although voting in a country may be compulsory, penalties for failing to vote are not always strictly enforced. In Australia and Brazil, providing a legitimate reason for not voting (such as illness) is accepted. In Argentina, those who were ill on voting day are excused by requesting a doctor to prove their condition; those over away from their voting place are also excused by asking for a certificate at a police station near where they are. Belgian voters can vote in an embassy if they are abroad or can empower another voter to cast the vote in their name; the voter must give a "permission to vote" and carry a copy of the eID card and their own on the actual elections.
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).
