The bicameral Philippine legislature, the Congress, consists of the Senate and the House of Representatives; members of both are elected by popular vote. The Senate is elected at large. There are currently 24 senators. Of a possible 250 members of the House of Representatives, 206 are elected from the single-member districts. The remainder of the House seats are designated for sectoral representatives elected at large through a complex "party list" system, hinging on the party receiving at least 2% to 6% of the national vote total. The upper house is located in Pasay City, while the lower house is located in Quezon City. The district and sectoral representatives are elected with a term of three years. They can be reelected but they are no longer eligible to run for a fourth consecutive term. The senators are elected to a term of six years. They can be reelected but they are no longer eligible to run for a third consecutive term. The House of Representatives may opt to pass a resolution for a vacancy of a legislative seat that will pave way for a special election. The winner of the special election will serve the unfinished term of the previous district representative; this will be considered as one elective term. The same rule applies in the Senate however it only applies if the seat is vacated before a regular legislative election. This case applies when Senator Teofisto Guingona was appointed Vice President before the May 2001 election. Senator Gregorio Honasan was in the 13th position in the Senatorial election and he served the unfinished term of Guingona. Honasan is no longer eligible to run for the 2004 elections. The case did not apply in 1998 when Gloria Arroyo was elected as Vice President and in 2004 when Noli de Castro was elected as Vice President.
