"Universal franchise is a key element of modern democracies. It is important that the right to vote and the process of voter registration are not unreasonably restricted on the basis of race, gender, religion, ethnic origin, past or present political affiliation, language, literacy, property or registration fees. However, the right to vote, may be subject to a number of reasonable conditions, the most usual being age, citizenship and residency. Furthermore, there might be provisions for clauses suspending political rights due to lawful detention, criminal convictions or mental incapacity. "
