2022 Philippine Senate election

The 2022 Philippine Senate election will be the 34th election of members to the Senate of the Philippines for a six-year term. It is scheduled to be held on May 9, 2022.
The seats of 12 senators elected in 2016 were contested during this election, and the senators that were elected in this election will serve up to June 30, 2028. The winners in this election will join the winners of the 2019 election to form the 19th Congress of the Philippines. The senators elected in 2019 will serve until June 30, 2025.
As the Senate election is held on the day when the presidency is also on the ballot, most presidential candidates may present slates of candidates for senator.
Background.
Hugpong ng Pagbabago (HNP), the electoral coalition backed by the Duterte administration, won nine of twelve seats, with three seats going to other parties and independents, and the primary opposition coalition, the Liberal Party-backed Otso Diretso, failing to win any seats. This led to the senators not affiliated with the Liberals to elect Tito Sotto to the Senate presidency in 2019. Sotto has not seen a challenge to his leadership to date, unlike in the House of Representatives.
Electoral system.
The Philippines has a 24-member Senate elected nationally. Every three years since 1995, 12 seats are disputed. For 2022, the seats disputed in 2016 will be contested. Each voter has 12 votes, of which one can vote one to twelve candidates, or a multiple non-transferable vote; the twelve candidates with the most votes are elected.
Senators are term limited to two consecutive terms, although they are eligible for a third (and succeeding) non-consecutive term. Only half of the seats are up in every senatorial election. The winning senators will succeed those elected in 2016, and will join those elected in 2019 in the 19th Congress.
Each party endorses a slate of candidates, typically not exceeding a 12-person ticket. A party may also choose to invite "guest candidates" to complete its slate. The party may even include, with the candidates' consent, independent candidates and candidates from other parties as the party's guest candidates. Parties also may form coalitions to endorse a multi-party slate of candidates.
Winning candidates are proclaimed by the Commission on Elections (COMELEC), sitting as the National Board of Canvassers. Candidates are proclaimed senators-elect if the thirteenth-place candidate no longer has a mathematical chance of surpassing the twelfth-place candidate. Post-proclamation disputes are handled by the Senate Electoral Tribunal, a body composed of six senators and three justices from the Supreme Court.
