Senators are elected to a term of six years. They can be re-elected but may not run for a third consecutive term. The House of Representatives may opt to pass for a vacancy of a legislative seat, which leads to a special election. The winner of the special election will serve the unfinished term of the previous district representative, and will be considered as one elective term. The same rule also applies in the Senate, however it only applies if the seat was vacated before a regular legislative election.
