Senate caucus convenes to set impeachment trial rules for VP Duterte

The minority is opposed to the presiding arrangement
A senator revealed the core tension at Friday's caucus over who would lead Vice President Duterte's impeachment trial.

Three days before a historic impeachment trial was set to begin, the Philippine Senate gathered behind closed doors to wrestle with a question that cuts to the heart of institutional legitimacy: who holds the gavel shapes how justice is perceived. Vice President Sara Duterte's fate now awaits not only the verdict of senators, but the procedural choices they make before a single witness is called. A quietly amended rule — one that loosens the Senate president's traditional grip on the presiding chair — has introduced both flexibility and friction into a process that demands the appearance, as much as the reality, of fairness.

  • The impeachment trial of Vice President Sara Duterte is set to open Monday, but the Senate adjourned its Friday caucus without resolving who will actually lead the proceedings.
  • A freshly amended Senate rule now allows the chamber to elect an alternative presiding officer by majority vote, breaking from decades of protocol that reserved the chair for the Senate president.
  • The lopsided caucus attendance — ten majority senators against two from the minority — made clear that the coalition with the votes also holds the power to decide who sits at the head of the trial.
  • Minority senators have signaled open opposition to the new presiding officer arrangement, raising questions about whether the trial's leadership will be seen as impartial or politically engineered.
  • With the name of Senator Francis Escudero surfacing as a possible alternative presider, the unresolved question of who holds the gavel now threatens to overshadow the substance of the trial itself.

The Philippine Senate convened in closed session on Friday to settle the procedural groundwork for an impeachment trial against Vice President Sara Duterte, scheduled to open on Monday, July 6. Twelve senators attended — ten from the majority coalition, two from the minority — a composition that quietly announced where the chamber's power resided before a single procedural vote was cast.

At the center of the caucus was a recently amended Senate rule that altered decades of practice. Traditionally, the Senate president presided over all impeachment trials, with one narrow exception for cases involving a sitting president. The new language preserved that default but introduced a condition: the chamber could now elect a different presiding officer by majority vote. The change was subtle in wording but significant in implication, opening a door that had long been sealed.

One senator, speaking without attribution, confirmed that the caucus focused on the trial's schedule and procedural framework. When the possibility of Senator Francis Escudero assuming the presiding role was raised, the response was telling: the minority was opposed. That objection suggested the majority was at least entertaining the idea — and that the two minority senators present understood the stakes of the choice.

When the caucus ended, the most fundamental question remained unanswered. Would Senate President Gatchalian preside as the rules nominally required, or would the majority exercise its new authority to install someone else? The minority's resistance signaled that they viewed the selection of a presiding officer not as a procedural formality, but as a decision with direct bearing on the trial's fairness and legitimacy. The trial was now seventy-two hours away, and the chamber had yet to agree on who would lead it.

The Philippine Senate gathered in closed session on Friday to hammer out the procedural details for an impeachment trial set to begin three days later. Vice President Sara Duterte faced removal proceedings scheduled for Monday, July 6, and the chamber needed to settle fundamental questions about how the trial would unfold—most pressingly, who would sit in the presiding officer's chair.

Twelve senators attended the caucus: Senate President Sherwin Gatchalian, Senate President Pro Tempore Vicente Sotto III, and nine others including Panfilo Lacson, Risa Hontiveros, JV Ejercito, Erwin Tulfo, Juan Miguel Zubiri, Francis Escudero, Loren Legarda, and Robin Padilla. The split was lopsided—ten from the majority coalition, two from the minority. The composition itself signaled where power lay in the chamber.

The central tension involved a recent change to Senate rules. Until now, the Senate president had always presided over impeachment trials, with a single exception carved out for cases involving the sitting president of the Philippines. The Senate had just amended that protocol. Under the new language, the Senate president would still normally preside—but only unless the chamber voted by majority to elect someone else instead. It was a subtle shift with real consequences. It opened the door to alternative leadership of the trial.

One senator, speaking anonymously to protect relationships in the chamber, confirmed that the caucus focused squarely on the trial's schedule and procedural framework. When asked whether Francis Escudero might take the presiding role, the senator offered a telling response: the minority was opposed. The comment suggested that the majority was at least considering it, and that the two minority senators present had made their objection known.

The amendment itself represented a departure from decades of practice. Previously, the rules had been explicit and inflexible: the Senate president presided in all impeachment cases except when the president of the Philippines stood trial. That clarity had been replaced with conditional language that required a majority vote to deviate from the default. The change gave the Senate flexibility but also introduced ambiguity into a process that demanded legitimacy and clarity.

What remained unresolved after the Friday caucus was whether the Senate would actually exercise that new power. Would Gatchalian preside as the rules nominally required, or would the majority vote to install someone else—perhaps Escudero, a senator with a reputation for judicial temperament? The minority's opposition suggested they feared the latter, and that they saw the choice of presiding officer as consequential to the trial's fairness.

The trial was now seventy-two hours away. The Senate had the procedural machinery in place, but the most basic question—who would lead the proceedings—remained unsettled. That ambiguity would hang over the chamber when the trial convened on Monday.

Why did the Senate need to change the impeachment rules at all? What problem were they trying to solve?

Model

The old rules locked the Senate president into the chair automatically. The amendment gave the majority flexibility to choose a different presiding officer if they wanted to—but it also meant the choice itself became political.

Inventor

And the minority opposed that flexibility?

Model

Yes. Two minority senators were in the room, and they signaled opposition to the idea of Escudero presiding. They seemed to understand that who sits in that chair shapes how the trial unfolds.

Inventor

Does it matter that much who presides?

Model

Absolutely. The presiding officer controls the pace, rules on procedural objections, manages witness testimony. In a trial where one side has overwhelming numbers, the presiding officer's temperament and fairness become the only real check.

Inventor

So the minority was protecting themselves?

Model

They were protecting the trial's legitimacy. If the majority installs a presiding officer seen as partisan, the whole proceeding loses credibility—even if the outcome was always predetermined.

Inventor

Did the caucus actually decide who would preside?

Model

The source doesn't say they did. They discussed it, the minority objected, and then the meeting ended. The question was still open when senators left the room.
