Political Constitution of Colombia (1991)

Voting is both a right and a duty of citizens. The State shall make sure that it is exercised without any type of coercion and in a secret manner in individual booths installed in every polling station, the use of electronic and computerized means of voting notwithstanding. In the elections of candidates ballot cards which are numbered and printed on a paper offering sufficient security guarantees may be used, and shall be distributed officially. The Election Commission shall also provide the voters with ballot papers on which the political movements and parties with legal personality and the candidates shall appear clearly identified and in equal conditions. An Act may establish voting mechanisms which provide additional and better guarantees for the free exercise of this right of the citizens.

The voting process for the election of members of a public body, governor, mayor or the first round of the presidential election must be repeated one single time when the blank votes constitute the majority of the total number of valid votes. In elections in which a single candidate is to be elected, the candidates of the first ballot may not run again, whereas in elections to public bodies the lists which have not attained the threshold may not be submitted.

The electronic vote may be introduced in order to achieve flexibility and transparency in all voting processes.
