15th Congress of the Philippines: The Senate

[last updated November 12, 2011]

The Philippine Senate has 24 members, elected at-large, with a term of six years. No Senator could serve for more than two consecutive terms. Half of its composition, or 12 seats, are up for election every three years.

In the 15th Congress, the Senate only has 23 members, due to the election of Benigno Aquino III, in the middle of his term, as the 15th President of the Philippines.

Senators Batch 2013

These are the Senators elected on May 14, 2007.

Senators (2007 - 2013)Re-elected were Sens. Edgardo Angara, Joker Arroyo, Panfilo Lacson, Francis Pangilinan and Manuel Villar, Jr.

Returning to the halls of the Senate were Loren Legarda, who served from 1998 to 2004; and, Gregorio Honasan, who previously served from 1995 to 2001, and from 2001 to 2004 (to complete the term of Sen. Teofisto Guingona, Jr., who was elected Vice President).

Outgoing Rep. Francis Escudero (Sorsogon, 1st District) is the son of longtime Sorsogon Rep. Salvador Escudero III. Aquilino Pimentel III is the son of outgoing Senator Aquilino “Nene” Pimentel, Jr.

Sen. Aquilino Pimentel III replaced Juan Miguel Zubiri, who resigned on August 3, 2011, in response to allegations of poll fraud during the 2007 Senatorial elections. Zubiri placed 12th, with only a 20,000-vote margin against 13th placer Pimentel. Pimentel assumed office on August 15.

Sen. Antonio Trillanes IV held office at the Senate only on December 2010, after being granted provisional release from prison. Trillanes was detained in July 2003, after seizing a hotel in Makati City to demand the resignation of then-President Gloria Macapagal-Arroyo. He committed the same act in November 2007, after walking out of his own trial.

Sen. Panfilo Lacson was absent in Senate sessions from January 2010 to March 2011. He went into hiding days before he was about to be formally charged by the Department of Justice for the murders of PR man Salvador “Bubby” Dacer and driver Emmanuel Corbito in 2000. He returned a month after the Court of Appeals dismissed the cases against him.
