Sara Duterte Impeachment Trial — September 14, 2026

Sara Duterte Impeachment Trial on September 14, 2026: Article II Opens with a Legal Framework on Unexplained Wealth

The Senate impeachment court began hearing Article II of Vice President Sara Duterte’s impeachment case on Monday, September 14, 2026. The article concerns allegations that Duterte acquired wealth disproportionate to her lawful income, failed to accurately disclose it in her Statements of Assets, Liabilities and Net Worth (SALNs), and did not divest from business interests after becoming vice president.

The prosecution presented retired Sandiganbayan Presiding Justice Amparo Cabotaje-Tang as its first witness for this phase. Her role was mainly to explain the legal principles that the court will later apply to bank, tax, corporate, anti-money-laundering, and SALN records. 

Article II begins

Day 24 marked the start of the third article in the prosecution’s order of presentation. The prosecution said it expected to use about 12 trial days and roughly 14 witnesses for Article II. Only Article III, which concerns alleged bribery, remained after this phase in the announced sequence.

The prosecution’s planned evidence included Anti-Money Laundering Council reports involving ₱6.77 billion in cumulative transactions associated with Duterte and her husband, lawyer Manases “Mans” Carpio, along with bank, tax, Securities and Exchange Commission, and SALN records from 2022 to 2024.

The transaction figure describes the volume of money that moved through the accounts. It is not, by itself, a finding that the couple owned ₱6.77 billion in unexplained wealth or that every transaction was unlawful.

Defense objects to Tang as a surprise witness

Defense lawyer Mark Vinluan asked the court to exclude Cabotaje-Tang, arguing that she was not named in the Articles of Impeachment or the pretrial order and that the defense had not received the materials related to her testimony in advance. He also described her presentation as the prosecution’s third use of a witness not properly disclosed ahead of time.

Presiding officer Chiz Escudero denied the motion. He ruled that the pretrial order allowed the prosecution to present additional witnesses.

During cross-examination, Vinluan questioned whether Tang was sufficiently objective to explain the legal framework. He asked about her unsuccessful applications for appointment to the Supreme Court during the administration of former President Rodrigo Duterte and whether she was “anti-Duterte,” a supporter of former Vice President Leni Robredo, or close to prosecutor Chel Diokno.

Tang said she had remained apolitical and agreed to testify because she was complying with a court subpoena. She also said she and Diokno had previously appeared as opposing counsel in cases involving former President Gloria Macapagal-Arroyo. When asked whether she had been promised anything in exchange for testifying, she denied it and said her testimony was not for sale.

The court’s decision allowed Tang to testify, but it did not decide whether her testimony would ultimately prove any allegation against Duterte.

What Tang explained about unexplained wealth

Tang told the court that wealth disproportionate to a public official’s salary and lawful income may be treated under the laws on public accountability as grounds for removal. She explained that the analysis can include property held in the official’s name and, in some circumstances, assets registered to a spouse, child, nominee, or other third party.

She also discussed the legal presumption under Republic Act No. 1379. In her explanation, wealth presumed to have been unlawfully acquired may be rebutted if the official gives a satisfactory account of how it was lawfully obtained.

Her testimony was presented as a legal framework for evaluating evidence. It was not a finding that Duterte’s wealth was unlawful or that the allegations in Article II had already been established.

SALNs, spouse’s assets, and business divestment

Tang testified that cash on hand and cash in bank should be declared separately in the cash portion of a SALN rather than placed under a general “others” category. She said repeated omissions could become a red flag suggesting intentional concealment, although an omission alone would not automatically prove unexplained wealth.

She also explained that a public official generally must declare a spouse’s assets unless the couple has a complete separation-of-property arrangement. If property is registered to a spouse or another person who lacked the financial capacity to acquire it, the court may examine whether ownership can be traced back to the public official.

On business interests, Tang said the Constitution and related public-accountability rules impose strict limits on the president and vice president participating in business. She told the court that divestment must take place within the required period after assuming office, which she identified as 30 days under the rules discussed during the hearing.

Again, these were explanations of the legal standards the prosecution intends to use. They did not settle whether Duterte complied with those standards.

Senator-judges test the limits of the testimony

Several questions from the senator-judges used hypothetical situations that resembled issues expected to arise from Duterte’s financial records.

One question asked what happens when billions of pesos pass through an official’s bank account but are not declared in the SALN, with the official claiming the money belonged to someone else. Tang said money in an account held in the official’s name generally must be declared, but she also emphasized that an omission alone does not prove unexplained wealth. The official must have an opportunity to explain whether the money was lawfully acquired or merely held temporarily.

She also said that money deposited and withdrawn before the end of the reporting year may not need to appear as an asset in that year’s SALN if it was no longer held at year-end. Such transactions could still raise questions for the AMLC or other investigators.

The questions helped define the issues for the next hearings, but no senator-judge made a final factual finding about Duterte’s accounts on September 14.

More financial records expected

Before the hearing ended, the court ordered Philippine National Bank and UnionBank to submit Duterte’s bank records by September 17. The deadline was described as non-extendable after the banks requested additional time to produce voluminous documents.

The prosecution also said it was considering documents concerning 19 overseas trips Duterte reportedly made from 2025 to 2026 as part of its broader presentation on alleged unexplained wealth.

The defense, meanwhile, raised questions about business interests reflected in President Ferdinand Marcos Jr.’s 2025 SALN, testing how broadly the witness’s interpretation of the business-participation rules should apply.

What Day 24 added to the case

September 14 moved the impeachment trial from the confidential-funds evidence under Article I to the financial and SALN issues under Article II. The prosecution introduced a legal framework for evaluating unexplained wealth, omitted assets, family-held property, proxies, and business divestment.

But the day’s testimony was not itself proof that Duterte acquired unlawful wealth. The court still had to examine the actual financial records, hear challenges from the defense, and decide whether the prosecution’s evidence met the required burden.

There was no conviction, acquittal, dismissal, or final ruling on September 14, 2026. The Senate impeachment trial remained ongoing.
