Article 48

All citizens, men and women, who have attained the age of majority, are entitled to vote. The vote is personal and equal, free and secret. The exercise of the vote is a civic duty. The law shall lay down the requirements and procedures for the exercise of the right to vote by citizens residing abroad and shall ensure its effectiveness. To this end, for the election of the Houses of Parliament, there shall be established an Overseas Constituency which will be allocated seats in the number set forth by a constitutional provision and in accordance with criteria determined by law. The right to vote cannot be restricted except for civil incapacity or by reason of an irrevocable criminal sentence or in cases of moral unworthiness specified by law.
