MANILA, Philippines — As the political machinery grinds toward an unprecedented institutional showdown in the capital, legal scholars are warning that the upcoming prosecution of the nation’s second-highest official hinges almost entirely on unmasking her financial trail. Former Ateneo School of Government Dean Tony La Viña stated that Vice President Sara Duterte’s official bank accounts could single-handedly decide the outcome of her upcoming trial.
Speaking at a public accountability forum at the University of the Philippines Diliman on Saturday, May 23, La Viña stressed that hiding these records from public scrutiny would deal a severe blow to the integrity of the state’s case.
The legal timing sets up a massive collision course between the executive branch and a volatile upper chamber, with the official impeachment calendar rapidly narrowing down:

“It might be fatal to the case if we do not see the official bank accounts of Sara Duterte,” La Viña told attendees at the forum, which was organized by the Taumbayan Ayaw sa Magnanakaw at Abusado Network Alliance (Tama Na). He emphasized that among the broad multi-point complaints filed against the Vice President, allegations centering on unexplained wealth and the systemic misuse of state confidential funds carry the greatest legal weight.
The push to subpoena the Vice President’s financial history follows explosive baseline disclosures submitted by the Anti-Money Laundering Council (AMLC) during initial House Committee on Justice hearings:

and 16 suspicious transactions (₱2.99B total).
In addition to the AMLC data, the prosecution is leveraging a major notice of disallowance issued by the Commission on Audit (COA) involving ₱73.28 million of the Office of the Vice President’s (OVP) 2022 confidential funds. COA recently upheld this decision in a definitive April 10, 2026 ruling, finding that the funds were funneled into activities completely detached from their intended national security mandates.
Despite the heavy paper trail compiled by state auditors and financial intelligence units, La Viña noted that securing an absolute conviction remains a steep climb due to a pair of intense structural barriers:
| Major Institutional Obstacles | Primary Operational Challenges & Countermeasures |
| 1. The Supreme Court Block | The defense camp is highly expected to file an immediate, aggressive appeal to the high court to legally seal the bank data under strict bank secrecy statutes. |
| 2. The 16-Vote Senate Margin | Conviction requires a supermajority of 16 affirmative votes out of the 24 sitting senators. Amid highly fluid Senate factions, locking down 16 votes is a monumental political challenge. |

Duterte’s legal representatives have previously countered the AMLC’s assertions, labeling the ₱6.7-billion figure as a “bloated, simple mathematical addition of multi-decade fund movements” rather than a representation of actual net personal wealth. However, prosecution allies counter that the sheer volume of unexplained cash inflows creates a massive discrepancy with her publicly declared Statements of Assets, Liabilities, and Net Worth (SALNs)—establishing a critical pattern of potential irregular enrichment that the Vice President must legally account for when the Senate floor officially transforms into an active courtroom this July.
