In its General Comment on Art. 25 of the ICCPR, the Human Rights Committee points to the connection between passive and active electoral rights: the effective implementation of the right and the opportunity to stand for elective office ensures that persons entitled to vote must have a free choice of candidates. The General Comment also emphasizes that any restrictions on the right to stand for election, such as minimum age, must be justifiable on objective and reasonable criteria and that persons who are otherwise eligible to stand for election should not be excluded by unreasonable or discriminatory requirements such as education, residence or descent, or by reason of political affiliation.
