The final prosecution witness
National Bureau of Investigation Director Melvin Matibag testified as the third and final prosecution witness on Article IV. He described the bureau’s continuing assessment of Vice President Sara Duterte’s public statements and said investigators were certain that she had contacted someone in connection with the alleged plan she described. At the same time, the NBI had not publicly identified that person. Matibag also referred to other publicly available material that the bureau considered in assessing what he described as a pattern relevant to the threat investigation.
The defense objects to hearsay and inference
The defense challenged portions of Matibag’s testimony as hearsay and questioned whether conclusions drawn from public reports or information gathered by other investigators could establish the truth of the underlying claims. That objection went to the difference between explaining why an agency acted and proving that the alleged conduct actually occurred. An investigator may describe an assessment, but the court must still decide which parts are admissible and how much evidentiary weight they deserve.
What the prosecution said it had proved
After cross-examination, the House prosecution ended its presentation on Article IV. Prosecutors said the combined testimony of Calilung, Lotoc and Matibag authenticated the recording, explained the NBI process and demonstrated the seriousness with which the bureau treated Duterte’s statements. They argued that the evidence was sufficient to require an answer from the defense. That claim did not shift the constitutional duty of the senator-judges, and it was not itself a judgment that the article had been proved.
What the hearings did and did not establish
The three witnesses created a record showing that the recording existed, that the NBI examined it and that bureau officials considered the statements serious. Still unresolved were Duterte’s intent, the identity and role of the person she allegedly contacted, whether a real operational plan existed and whether the conduct constituted betrayal of public trust or another impeachable offense. The defense was entitled to present evidence and alternative interpretations before the court reached any conclusion.
Why It Matters to Us, Filipinos
Article IV tested more than one controversial statement. It tested how the country responds when the language of a senior official appears to invoke political violence. The state cannot casually dismiss such language, especially when it names public officials and refers to killing. But a constitutional trial must also resist turning agency opinion into automatic proof. Filipinos deserve a process that is serious about threats, careful with evidence and honest about what remains uncertain.
What happens next
With the prosecution resting Article IV, attention moved toward the remaining impeachment articles, financial records and proposed changes to the order of presentation. The defense would later have the opportunity to answer the alleged-threat charge and challenge the prosecution’s theory as a whole.
