The Senate of the Philippines (Filipino: Senado ng Pilipinas, also Mataas na Kapulungan ng Pilipinas or "upper chamber") is the upper house of the bicameral legislature of the Philippines, the Congress; the House of Representatives is the lower house. The Senate is composed of 24 senators who are elected at-large with the country as one district under plurality-at-large voting.
Senators serve 6-year terms, with half of the senators elected every three years to ensure that the Senate is maintained as a continuous body, though staggered. When the Senate was restored by the 1987 Constitution, the 24 senators who were elected in 1987 served until 1992. In 1992 the candidates for the Senate obtaining the 12 highest number of votes served until 1998, while the next 12 served until 1995. Thereafter, each senator elected serves the full 6 years.
Aside from having its concurrence on every bill in order to be passed for the president's signature to become a law, the Senate is the only body that can concur with treaties, and can try impeachment cases. The Senate Presidency is currently held by Franklin Drilon.
