THE prosecution’s decisive challenge is no longer merely reaching a legal threshold of 14 votes; it is making conviction politically defensible to senators whose judgment will turn on both the evidence and public legitimacy. For months, the arithmetic of Vice President Sara Duterte’s impeachment trial was brutal and simple: 16. Sixteen of 24 senator-judges had to say “guilty,” and anyone who could count the Senate’s blocs knew the prosecution was stuck short of that line.
Then, on Sept. 23, the legal threshold moved. Senator-judges voted 13 to 1, with six Duterte allies abstaining, to interpret the two-thirds verdict required from “all members of the Senate” as counting only those legally and factually capable of participating. With four senators unable to take part, prosecutors now need 14 votes instead of 16; the Supreme Court has since rejected petitions challenging that rule.
The four exclusions are publicly identifiable but arise from different circumstances: Jinggoy Estrada and Rodante Marcoleta are detained while facing separate plunder charges; Bato dela Rosa remains out of public view after the International Criminal Court reportedly issued an arrest warrant over his alleged role in the drug war; and Loren Legarda has been on medical leave since early August. The court now targets a verdict by Dec. 16.
The legal question is settled for this trial; the political question is not. The prosecution appears to have 13 votes to preserve, but it still needs one senator willing to make conviction publicly defensible.
It is tempting to treat the 13 who lowered the threshold as 13 votes to convict, but that is inference, not fact. A vote on how to count is not a vote on guilt: some may have backed the new rule because they accepted its legal reasoning, not because they had decided the allegations involving confidential funds, bribery, or assassination threats.
Risa Hontiveros, Kiko Pangilinan and Bam Aquino are no secret. But the 13 also include senators who have built careers on reading the public mood, which means the prosecution’s first job is not finding a 14th vote; it is keeping the 13 it appears to have.
Escudero was the lone dissenter on Sept. 23. But he said that while he took exception to the decision, he accepted it as the court’s judgment. That was a defense of his procedural position, not a signal of his verdict.
Escudero matters because a guilty vote from the lone procedural dissenter would be unusually persuasive. But that possibility remains a political reading, not a declared position, and his cross-camp instincts counsel caution.
The most consequential name may belong to someone who has not sat in the court since August. Legarda is being treated in France for a serious lung condition, with a leave that now runs to Oct. 9. Her spokesman, Tony La Viña, says she is eager to come home but will return only when treatment is done.
Could she vote? Erwin Tulfo has argued that any senator physically present on voting day may cast a ballot, even one who missed the hearings, while La Viña has admitted he is unsure which reading will prevail. If Legarda returns, she could add a vote without raising the threshold, making her absence or presence central to the prosecution’s path.
Legarda has not publicly aligned herself with Duterte, and her camp says it will not rule out rejoining the Senate majority. An Ombudsman probe involving solar energy deals linked to her and her son adds pressure, but whether that pushes her toward independence or caution is unknowable from the public record.
Then there is legitimacy. A senator who missed the entire trial and arrives in December to cast the deciding vote would face fair questions about whether she weighed the evidence. With the court recessing from mid-October to late November, Legarda has time; if she means to judge this case, she should be back while the defense is still presenting it.
Mark Villar broke with the minority to back the new threshold while his bloc-mates sat it out. He is already one of the 13, which makes him a swing vote in reverse: if he stays, the prosecution is one away; if he retreats, it needs two.
Camille Villar remains harder to read: her emotional defense of absent minority colleagues showed loyalty to colleagues, not necessarily to the vice president. Until the evidence and public mood harden, any forecast that the Villars would follow an emerging majority remains speculation.
Bong Go and Robin Padilla are widely regarded as highly unlikely to convict, given their longstanding political alignment with the Duterte family. Imee Marcos, who has repeatedly sided with the Dutertes even against her brother’s political interests, would also be an improbable defector; Alan Peter Cayetano, as minority leader, is another unlikely source of the decisive vote.
The 14th senator will not be secured through arithmetic alone. As the prosecution closes its case on alleged ill-gotten wealth and the defense prepares its response, the record must become strong enough that conviction can be defended as a judgment on proved misconduct, not political convenience.
That standard is the final test: no senator wants to cast the vote that saves a vice president the public believes is guilty or removes one the public believes was railroaded. The decisive vote will go only where evidence and legitimacy converge.
The Senate may have changed how it counts, but history will judge why it counted that way. In the end, the prosecution still bears the harder burden: proving misconduct so clearly that the 14th vote can answer not only to politics, but to history.
