Quorum shortage halts Day 38 of Sara Duterte impeachment proceedings

PHILIPPINE SENATE, MANILA, 13 OCTOBER 2026 —

Vice President Sara Duterte’s Impeachment Trial Hit by Quorum Delays as Minority Senators Raise Constitutional Concerns

The incident marks the second quorum shortfall in less than a week, raising doubts about the trial’s stability as it approaches the defense’s evidence phase. The absence of key minority senators—including Imee Marcos, Alan Peter Cayetano, and Bong Go—has fueled speculation that their participation may be contingent on addressing what they describe as "distortions" in the trial’s conduct.

Meanwhile, the defense’s upcoming evidence presentation, scheduled to begin November 9, could further test the court’s cohesion amid escalating tensions.

The trial’s procedural hurdles come amid broader legal challenges. Padilla and Go previously filed a petition with the Supreme Court (SC) contesting the September 23 decision to lower the conviction threshold from a two-thirds majority to a simple majority, a move they argue violates constitutional safeguards.

Padilla’s weekend remarks—accusing the court of "disregard for law"—sparked a rebuke from fellow senator-judge Panfilo "Ping" Lacson, who demanded clarity on whether the criticism targeted the entire court or specific individuals. Lacson’s response underscored the trial’s fracturing alliances, with minority senators increasingly framing their absence as a protest against perceived judicial overreach.

The quorum issue emerged shortly after the opening prayer led by senator-judge Mark Villar, with only 11 of the 24-member court present at 10:00 AM. The court ultimately proceeded with 13 senators, a number that has become the norm in recent sessions, deviating from the usual attendance of 14 to 15. The afternoon session saw the return of Bong Go and Pia Cayetano, though Imee Marcos remained absent, leaving the court’s composition precarious.

The trial’s presiding officer, Chiz Escudero, has faced scrutiny over procedural decisions, including the lowered conviction threshold, which Padilla and others argue undermines the impeachment process’s integrity.

The trial’s economic and political stakes were highlighted during Monday’s proceedings, when foreign financial analyst Alexander Cabrera testified that Vice President Duterte’s undeclared wealth could total as much as ₱1.5 billion from 2022 to 2025, based on financial records reviewed by the court. Padilla and other minority senators interjected during Cabrera’s testimony, signaling their intent to challenge the prosecution’s evidence.

The defense’s anticipated evidence phase, beginning November 9, may further expose inconsistencies in the trial’s conduct, particularly if minority senators continue to boycott sessions or demand procedural reforms.

The trial’s implications extend beyond political optics, with potential ripple effects for Malaysia’s regional neighbors grappling with similar governance challenges. In Malaysia, the impeachment process—though not a direct parallel—has drawn comparisons to domestic debates over accountability in high-office corruption cases, such as those involving former officials under the previous administration.

The Philippine case serves as a cautionary example of how institutional divisions can derail judicial proceedings, raising questions about the resilience of checks and balances in Southeast Asia’s democracies.

For the Philippine markets, the trial’s volatility has already sparked speculation about economic stability, particularly given Vice President Duterte’s role in policy formulation. The Philippine Stock Exchange (PSE) has seen muted reactions to the impeachment proceedings, but analysts note that prolonged uncertainty could deter foreign investment.

The defense’s evidence phase, if marred by further quorum issues or legal challenges, may exacerbate market jitters, particularly in sectors sensitive to political risk, such as real estate and financial services. The trial’s outcome could also influence regional capital flows, as investors weigh the Philippines’ governance trajectory against peers like Thailand and Indonesia, which have faced their own political turbulence.

The trial’s next critical juncture will be the defense’s evidence presentation, scheduled to begin November 9. If minority senators continue to boycott sessions or escalate their legal challenges, the court’s ability to proceed may face further obstacles. The Supreme Court’s eventual ruling on the lowered conviction threshold petition could also reshape the trial’s trajectory, potentially forcing a rehearing or altering the procedural framework.

For now, the Senate impeachment court remains in limbo, with the fate of Vice President Duterte’s tenure hanging on the fragile consensus of its fractured membership.
