MANILA, Philippines — The impeachment trial of Vice President Sara Duterte is entering a critical procedural stage as House prosecutors move to formally submit documentary and other evidence supporting their remaining allegation of unexplained wealth.
The formal offer of evidence is a significant step in the Senate impeachment proceedings because it identifies the exhibits prosecutors want the impeachment court to admit and consider in deciding the case. However, filing evidence does not automatically mean that the court has accepted every exhibit or that the allegations have been proven.
The case has drawn renewed attention after prosecutors narrowed their impeachment strategy to focus on Article II, which concerns allegations of unexplained wealth, potentially undeclared assets and business interests involving Duterte and her husband, lawyer Manases “Mans” Carpio.
Why the formal offer matters
A formal offer of evidence allows prosecutors to identify the documents and other exhibits they want the Senate impeachment court to consider. The defense can challenge the admissibility, relevance or evidentiary value of those materials before the court determines which items may be considered.
According to reports by GMA News and the House of Representatives, prosecutors had been preparing their submission following the conclusion of their presentation of evidence. The Senate impeachment court set an October 23 deadline for the formal offer, while the defense was given time to submit its comments and objections.
The next major question is how the impeachment court will rule on the submitted exhibits and how the defense will respond to the prosecution’s financial allegations.
Prosecutors cite alleged ₱817.87-million wealth discrepancy
One of the most consequential points in the prosecution’s presentation came from forensic accounting expert Alexander Cabrera.
According to the House prosecution’s account of his testimony, Cabrera estimated that approximately ₱817.87 million in assets and income involving Duterte and Carpio from 2022 to 2025 remained unexplained under his analysis. He also discussed a higher estimate of as much as ₱1.5 billion under less conservative assumptions.
The figures were based on his examination of financial materials, including bank records, income tax returns, insurance documents, corporate filings and Statements of Assets, Liabilities and Net Worth, or SALNs.
These figures represent the expert’s findings as presented by the prosecution. They should not be interpreted as a final judicial determination that Duterte or Carpio unlawfully acquired or concealed wealth.
The defense has disputed the allegations, and the evidence must be evaluated through the impeachment process.
Why prosecutors dropped three other impeachment articles
The formal offer comes after a major change in the prosecution’s strategy.
On October 13, the Senate impeachment court accepted the prosecution’s withdrawal of three of the four impeachment articles, leaving Article II on alleged unexplained wealth as the remaining charge in the trial.
The withdrawn articles involved allegations concerning the misuse of confidential funds, bribery, and grave threats or an alleged assassination plot. The withdrawal narrowed the scope of the impeachment proceedings and reduced the number of issues the Senate must address in the remaining trial.
GMA News reported that prosecutors viewed the decision to concentrate on Article II as a legal strategy intended to keep the proceedings from dragging on into 2027. The defense, however, has maintained that it will decide independently how to present its case.
The withdrawal of the articles from the impeachment trial should not, by itself, be interpreted as a judicial finding that every underlying allegation was either true or false. Separate allegations may be subject to other legal processes where applicable.
What happens next in Sara Duterte’s impeachment trial?
The immediate issue is the admissibility of the prosecution’s exhibits.
After the formal offer, the defense may submit objections and comments. The Senate impeachment court must then determine how to treat the evidence before the proceedings move forward.
The defense is expected to begin presenting its evidence when the trial resumes, with November 9 identified in previous reports as the scheduled date, subject to the court’s procedural decisions.
The remaining case is therefore likely to turn on how the Senate evaluates the documentary record, the expert testimony and the defense’s responses—not simply on the size of the figures cited by prosecutors.
A consequential test for the impeachment court
The formal offer marks an important transition from presenting witnesses to determining which evidence the court may properly consider.
For the prosecution, the challenge is to demonstrate that its financial analysis and supporting documents substantiate the allegations under Article II. For the defense, the task is to contest the prosecution’s interpretation and present its own account of the evidence.
The outcome remains uncertain. The Senate impeachment court’s assessment of the evidence, together with the defense’s presentation, will be central to determining the direction of the case.
For now, the central question is whether the prosecution’s documentary record will withstand the defense’s objections and persuade the Senate that the remaining impeachment charge has been established under the applicable standard.
