01

Witnesses and evidence

Col. Manaros M. Boransing II testified that his duties as the 1st Infantry Division's civil-military operations officer included advising the commander, drafting plans, supervising implementation and collecting data from subordinate units.

Col. Magtangol G. Panopio testified that he formally learned during the October 17, 2024 House hearing that DepEd had used his December 5, 2023 certification as a liquidation document; he said the certification attested that YLS activities occurred in his unit's area, not to money or funds.

02

Prosecution position

The prosecution offered Boransing's testimony to show that the 1st Infantry Division conducted its 2023 YLS and IEC activities without DepEd confidential funding and that his certification did not identify information sources, informer payments or a link to DepEd confidential funds.

The prosecution argued that DepEd submitted Army certifications to COA as support for ₱15.54 million reportedly paid as rewards from confidential funds, although the cited activities were planned, funded and conducted by the Army and local governments.

After the parties narrowed the AFP proof, the prosecution offered Panopio to show that he did not know his certification would be used in DepEd's confidential-fund liquidation and that his unit did not receive or know of receiving confidential information from DepEd for the activities.

03

Defense position

The defense argued that the certifications described collaboration with DepEd and that one stated the summit locations were identified through information primarily obtained from DepEd.

The defense declined to stipulate that the officers were unaware their certifications would be used in DepEd's COA response, pointing to language that the documents were issued for whatever legal purpose they might serve.

04

Senator-judge interventions

Senate President Sherwin Gatchalian asked whether DepEd supplied confidential or surveillance information for the activities; Boransing said the 1st Infantry Division received none and described DepEd's inputs as open-source information about students.

Erwin Tulfo asked whether the YLS and IEC were community-relations rather than intelligence-gathering activities; Panopio agreed and limited his answer to civil-military operations.

05

Court rulings and directions

The court barred testifying witnesses from possessing or accessing communication devices or receiving prompts until they were discharged, and directed the clerk to secure the devices and obtain confirmation from each witness.

The chair ordered that the stipulated COA, DepEd, AFP-certification and related documents required no further proof apart from completing the witness narration.
