Philippine politics just crossed a point of no return. The Senate is convening as an impeachment court on Monday, May 18, 2026, to decide whether to permanently remove Vice President Sara Duterte from office and strip away her right to ever run again. If you think this is just standard legislative theater, you're missing the bigger picture.
This isn't a mere policy dispute. It's a brutal, zero-sum war between the country's two most powerful political dynasties: the Marcoses and the Dutertes. What happens in that Senate hall over the coming weeks will determine who rules the Philippines long after President Ferdinand Marcos Jr. steps down.

The House of Representatives delivered a massive blow on May 11, voting 257 to 25 to send the articles of impeachment to the upper house. But don't assume her removal is a done deal. The Senate is a completely different beast, and a wild leadership shakeup just threw the entire trial into absolute chaos.
The Absolute Chaos Behind the Senate Doors
To understand why this trial could explode into a complete standstill, look at the dramatic events of the past week. Right as the House prepared to impeach Duterte, a political earthquake struck the Senate. More reporting by The Guardian delves into comparable perspectives on the subject.
Senator Ronald “Bato” dela Rosa, a fierce Duterte loyalist and former national police chief, suddenly emerged from six months in hiding. Dela Rosa has been evading arrest from the International Criminal Court (ICC), which is investigating the bloody drug war led by Sara’s father, former President Rodrigo Duterte. Dela Rosa dashed into the Senate plenary hall, claimed sanctuary, and managed to cast a decisive vote that ousted Senate President Vicente Sotto III.
In Sotto's place, the pro-Duterte faction installed Alan Peter Cayetano as the new Senate President. This means Cayetano—a long-time Duterte ally—is now the presiding officer of the very court tasked with trying the Vice President. It's an unbelievable tactical outflanking that nobody saw coming.
Prosecuting the Vice President just got exponentially harder. The minority bloc, led by Senators Erwin and Raffy Tulfo, insists they're fully prepared to proceed with the trial at 3 p.m. on Monday. They argue that the Senate owes it to the public to hold the proceedings without delay. But with Cayetano holding the gavel and rumors of yet another leadership coup swirling through the hallways, the balance of power has completely shifted. To convict Duterte, the prosecution needs a two-thirds majority—16 out of 24 senators. Right now, achieving that number looks like a nearly impossible mountain to climb.
The Serious Charges Stripping the Vice Presidency of Peace
The allegations leveled against Sara Duterte are massive, spanning multiple complaints consolidated by the House Committee on Justice under Representative Gerville Luistro.
- Misuse of Public Funds: The heart of the financial case involves massive, unexplained bank transactions and the alleged mishandling of secret confidential funds during her tenure as Vice President and Secretary of Education.
- Unexplained Wealth: Lawmakers claim Duterte failed to declare significant assets in her Statement of Assets, Liabilities, and Net Worth (SALN), a direct violation of anti-graft laws.
- Death Threats Against the President: The most sensational charge stems from a bizarre, public online press conference where Duterte explicitly warned that she had hired an assassin to kill President Marcos, First Lady Liza Araneta-Marcos, and former House Speaker Martin Romualdez if she herself were to be assassinated.
Duterte hasn't answered these specific criminal allegations in detail. Instead, her legal team argues that the charges are entirely fabricated and politically motivated. Her husband, Manases Carpio, even filed criminal counter-complaints against legislative officials, claiming that the public disclosure of their bank records violated the country’s strict bank secrecy laws.
This entire spectacle is actually Duterte’s second impeachment battle. The House managed to impeach her in early 2025, but she successfully ran to the Supreme Court, which nullified the case on a technicality involving a constitutional "one-year bar rule." That legal shield officially expired early this year, allowing the Makabayan bloc and allied groups like Tindig Pilipinas to unleash a fresh barrage of complaints that stuck.
What Lies Ahead for the Filipino People
This trial isn't happening in a vacuum. The timing couldn't be worse for the country's stability. The Philippines is currently grappling with a massive domestic corruption crisis and an aggressive economic pinch caused by global oil-price spikes. Layering a constitutional crisis on top of an unstable economy is a dangerous gamble.
The real prize here is the 2028 presidential election. Ferdinand Marcos Jr. is constitutionally limited to a single term and cannot run again. Before their bitter fallout, Sara Duterte was widely considered the frontrunner to succeed him. If the Senate convicts her, her political career is dead, and the Marcos faction secures its grip on the state. If she wins an acquittal, she emerges as an incredibly powerful political martyr with a clear path to Malacañang Palace.
If you are trying to track where this crisis goes next, keep your eyes on three specific variables over the next forty-eight hours:
- Watch the Gavel: Monitor whether the anti-Duterte minority tries an immediate counter-coup to unseat Alan Peter Cayetano before the formal reading of the articles of impeachment begins.
- Track the ICC Wildcard: Keep tabs on whether the National Bureau of Investigation attempts to enter the Senate grounds to enforce the international arrest warrant against Senator Dela Rosa, which would trigger a massive constitutional standoff between the executive branch and the legislature.
- Monitor Public Opinion: Watch the streets of Manila. Sara Duterte remains incredibly popular among a large segment of the population, and any sign of massive, organized public protests could quickly spook swing-vote senators who are worried about their own re-election bids in the upcoming midterms.
