A special election will be held in Negros Oriental's 3rd congressional district on December 9, 2023, to fill the district's vacant seat in the House of Representatives of the Philippines for the remainder of the 19th Congress.

The vacancy arose when the House of Representatives expelled the incumbent, Arnolfo Teves Jr. Teves had refused to return to the country after being tagged as the mastermind behind the assassination of the governor of Negros Oriental, Roel Degamo.

Electoral system

Each congressional district of the Philippines sends one representative to the House of Representatives. An election to the seat is via first-past-the-post, in which the candidate with the most votes, whether or not one has a majority, wins the seat. Based on Republic Act (RA) No. 6645, for a special election to take place, the seat must be vacated, the relevant chamber notifies the Commission on Elections (COMELEC) the existence of a vacancy, then the COMELEC schedules the special election. There is a dispute in the procedure as a subsequent law, RA No. 7166, supposedly amended the procedure, bypassing the need for official communication from the relevant chamber of the vacancy. The COMELEC has always waited on official communication from the relevant chamber before scheduling a special election.

Meanwhile, according to RA No. 8295, should only one candidate file to run in the special election, the COMELEC will declare that candidate as the winner and will no longer hold the election.

Background

Arnolfo Teves Jr. defended his House seat in the May 2022 elections. His brother, then Bayawan mayor Pryde Henry Teves, defeated incumbent Roel Degamo for governor of Negros Oriental. Degamo appealed his defeat, saying a third candidate, Ruel Degamo, caused confusion and took away his votes.

In October 2022, the Commission on Elections disqualified Ruel Degamo, allocating his votes to the defeated governor, allowing the latter to emerge as the candidate with the highest number of votes. The commission then proclaimed erstwhile governor Degamo as the actual winner. Governor Teves sought relief from the Supreme Court, but later relinquished the governorship later that month. In February 2023, the Supreme Court dismissed Teves's petition, affirming Degamo's victory.

On March 4, 2023, Degamo was assassinated by unknown assailants in his Pamplona residence. Aside from Degamo, nine other people died in the attack. Former members of the Armed Forces of the Philippines were implicated in the attack. Degamo's wife, Pamplona mayor Janice Degamo, said that the mastermind was "very known in the country today" but did not specify any name. The arrested suspects implicated a certain "Cong Teves" as the mastermind. In a privilege speech, TGP congressman Jose "Bong" Teves Jr. denied he was the "Cong Teves" mentioned, saying that while he shared the surname, his family hails from Catanduanes and not Negros. Arnolfo Teves Jr. said that he could not be the mastermind, as he was undoing stem cell treatments in the United States when the attack took place. Teves was previously cleared to travel abroad for a "personal trip", and it was set to expire on March 9, 2023.

On March 22, Teves was then unanimously suspended by the House of Representatives for 60 days, then he refused to return to the Philippines, citing threats to his life. In May 2023, Timor-Leste rejected Teves's request to seek political asylum in their country. Speaker Martin Romualdez urged Teves to come home, threatening additional disciplinary action if he doesn't do so. On another unanimous vote, he was then suspended for another 60 days. On July, the Teves brothers were designated as terrorists by the Anti-Terrorism Council.

Teves was expelled by the House on August 16, 2023, for "continued pursuit of political asylum," "indecent behavior" and "continued absence", becoming the first congressman to be expelled since the restoration of Congress in 1987. Only three lawmakers, all from the Makabayan bloc, abstained from the otherwise unanimous vote, citing the inclusion in the House committee report of Teves being designated as a terrorist by the Anti-Terrorism Council, of which its creation Makabayan opposes. According House Secretary-General Reginald Velasco, Teves was the first legislator expelled without being convicted of a crime. The House then declared Teves's seat as vacant, seeking for a special election.

Later that month, the Department of Justice announced that they will file murder charges against Teves in a Manila Regional Trial Court (RTC) in relation to the Pamplona attack. A Manila RTC then issued a warrant of arrest against Teves and nine others on early September.
