The candidate who receives a majority of valid votes cast shall be elected mayor.

If no candidate receives a majority of votes, a second round of elections shall be held between the two candidates receiving the most votes. If multiple candidates receive the same highest number of votes, or if two or more candidates receive the same second-highest number of votes, the candidates for the second round of elections shall be decided by drawing lots. The ballot paper shall list the candidates in the order of the number of votes received in the first round of elections. If the number of votes received is equal, the order shall be determined by drawing lots.

The second round of regular elections shall be called by the National Electoral Commission, while the second round of all other elections shall be called by the municipal electoral commission. The second round of elections shall be held 14 days after the first round of elections.
