Nomination rules in elections regulate the conditions under which a candidate or political party is entitled to stand for election. The right to stand for election is sometimes called passive suffrage, as distinct from active suffrage, which is the right to vote. The criteria to stand as a candidate depends on the individual legal system. They may include the age of a candidate, citizenship, endorsement by a political party and profession. Laws restrictions, such as competence or moral aptitude, can be used in a discriminatory manner. Restrictive and discriminatory nomination rules can impact the civil rights of candidates, political parties, and voters.
