Voting for senators is via nationwide, at-large basis via plurality-at-large voting system. A voter has twelve votes: the voter can vote less than twelve but not more than it. Then votes are tallied nationwide and the twelve candidates with the highest number of votes are elected to the Senate. The Commission on Elections administers elections for the Senate, with the Senate Electoral Tribunal deciding election disputes after a Senator has taken office.
