There is nothing quite as magical in Philippine democracy as watching a 24-member Senate suddenly discover the fine art of fractions. When retired Supreme Court Chief Justice Reynato Puno took to the rostrum on September 16, 2026, as an amicus curiae (friend of the court) in the impeachment trial of Vice President Sara Duterte, he gave lawmakers a masterclass in constitutional law. But for the veteran politicians in the gallery, the lesson sounded remarkably like a high-stakes numbers racket.
At the center of the spectacle is Article XI, Section 3(6) of the 1987 Constitution, which demands the concurrence of "two-thirds of all the Members of the Senate" to convict an impeached official. In normal times, basic elementary school arithmetic dictates that two-thirds of 24 is 16. But in the theater of Philippine politics, "normal" is a myth and constants are negotiable.
The Flexible Denominator: Constitutional Nuance or Trapong Mahika?
Puno, flanked by fellow legal heavyweights Hilario Davide Jr. and Artemio Panganiban, argued for a "contextual and functional" interpretation of the voting base. Drawing upon the historic 1949 precedent of Avelino v. Cuenco, Puno explained that the denominator does not have to be mathematically carved in stone at 24. If a senator dies, resigns, is legitimately expelled, or languishes under lawful detention outside the coercive jurisdiction of the Senate, the voting threshold can shrink accordingly.
Yet Puno was quick to issue a stern constitutional warning that sent chills through the plenary: the Senate cannot simply engineer exclusions out of thin air. Arbitrarily disqualifying senator-judges or trampling upon the respondent's due process rights constitutes grave abuse of discretion—an open invitation for the Supreme Court to step in and blow up the entire trial into legal oblivion.
The Miraculous Timing of Philippine "Lawfare"
Of course, this is where the legal theory crashes headfirst into the swamp of Philippine political reality. Observers could not help but notice the sudden, almost divinely inspired efficiency of the justice system in recent weeks. Complaints, ethics probes, and Ombudsman subpoenas targeting key senators—such as Rodante Marcoleta, Jinggoy Estrada, and other vocal figures—seemed to sprout with impeccable comedic timing just as the impeachment numbers began tightening.
In a country where ordinary court dockets gather dust for decades, the lightning-fast resurrection of legal liabilities ahead of a historic vote has all the hallmarks of classic political lawfare. If you can't convince a senator to vote against the respondent, you simply suspend them, jail them, or threaten them into inhibiting. Reduce the denominator from 24 down to 21, and suddenly the mountain of 16 votes becomes a much more manageable molehill of 14.
Senatorial Gymnastics: The Art of Political Survival
Then there is the acrobatic choreography of the Senate itself. Political heavyweights and fence-sitters—from Senate President Francis "Chiz" Escudero to Joel Villanueva—find themselves performing Olympic-level balancing acts. Every press statement is framed as solemn fidelity to constitutional duty, even as rumors swirl of backroom arm-twisting, threatened committee chairmanships, and midnight realignments.
When senators switch tones overnight from fiery defenders to cautious agnostics, the public knows better than to credit sudden intellectual enlightenment. In the arena of Philippine dynastic warfare, survival instinct always trumps party loyalty.
"When the Constitution says 'two-thirds of all members,' it envisioned a court of statesmen, not a casino table where players are systematically disqualified until the house wins."
The Real Danger at Padre Faura
What makes Chief Justice Puno’s testimony crucial is the reminder that political hubris has consequences. The Senate may pride itself on being the sole master of its impeachment rules, but a conviction engineered through manufactured absences, intimidation, or procedural disenfranchisement is a hollow victory.
If lawmakers treat the Constitution like silly putty to achieve a predetermined verdict, they risk turning the entire impeachment process into a constitutional crisis that the Supreme Court will inevitably have to dismantle. For now, the Filipino public is left watching another classic episode of national drama: where principles are cheap, timing is suspect, and the math always conveniently favors whoever holds the gavel.
