Age of candidacy is the minimum age at which a person can legally qualify to hold certain elected government offices. In many cases, it also determines the age at which a person may be eligible to stand for an election or be granted ballot access. The first known example of a law enforcing age of candidacy was the Lex Villia Annalis, a Roman law enacted in 180 BCE which set the minimum ages for senatorial magistrates. Many youth rights groups view current age of candidacy requirements as unjustified age discrimination. Occasionally people who are younger than the minimum age will run for an office in protest of the requirement or because they don''t know that the requirement exists. On extremely rare occasions, young people have been elected to offices they do not qualify for and have been deemed ineligible to assume the office.
