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.
Mandated choice
Mandated choice or mandatory choice is an approach to public policy questions in which people are required by law to state in advance whether or not they are willing to engage in a particular action. The approach contrasts with "opt-in" and "opt-out" ("presumed consent") models of policy formation. The approach has most frequently been applied to cadaveric organ donation, but has increasingly been considered for advance directives as well. One bioethicist, in advocating for a mandatory choice model for living wills, argues that "while all Americans should have a right to decide how they want their lives to end, it does not follow that they should be able to avoid confronting such a choice."
