San Juan City lone district Rep. Ysabel Maria Zamora has echoed the notion that alleged non-disclosure of certain statements of assets, liabilities and net worth (SALN) details is enough to get an official impeached.

Speaking in an online interview Monday, Zamora--a vice chairperson of the House Committee on Justice that's handling the impeachment case against Vice President Sara Duterte--cited the impeachment case of the late Supreme Court (SC) Chief Justice Renato Corona.

“The non-disclosure of certain assets or even just one asset in the SALNs and the failure to show the proper increase or the reason for that increase was, well, that was used against Corona,” Zamora said.

Corona was impeached by the House of Representatives and subsequently convicted by a Senate impeachment court in 2012 for failing to fully disclose his assets, including bank accounts not reflected in his SALN.

The case established that even a single material omission or an unexplained increase in wealth could constitute a violation of the Constitution and grounds for impeachment under betrayal of public trust.

Earlier, Manila 6th district Rep. Bienvenido "Benny" Abante Jr. an endorser of one of the two active impeachment complaints filed against Duterte, pointed to the Corona case as proof that accountability mechanisms hinge on compliance to constitutional requirements, such as the truthful execution of one's SALN.

“During the time of Chief Justice Corona, isa lang naman nakapag-convict sa kanya (he was convicted because of just one offense)…He was not able to declare all his assets in his SALN,” Abante said.

The 2026 impeachment complaints against the Vice President has placed a focus on her SALNs, among the other allegations that have technically remained unanswered since her 2025 impeachment case.

Zamora said the justice panel subpoenaed last week Duterte’s SALNs to determine whether assets were properly declared and whether increases in wealth were adequately explained.

The complaints allege non-disclosure of assets and discrepancies in Duterte’s financial declarations, as well as possible links to bank accounts and corporate interests not reflected in her SALNs.

The committee has also sought records from the Securities and Exchange Commission (SEC) to examine these alleged connections.

Zamora said the SALN review forms part of a broader set of allegations being examined by the panel, including possible ill-gotten wealth.

“In the last hearing (March 25), we identified the issues or the grounds by which we will conduct our hearing on probable cause. And yes, ill-gotten wealth was mentioned in the complaint as well,” she said.

The panel has ordered the production of Duterte’s SALNs covering her years in public office, along with related financial and corporate records, to trace the source and movement of her declared wealth.

The impeachment complaints also include allegations of misuse of P612.5 million worth of confidential funds, alleged threats against President Marcos and other officials, and other acts categorized under bribery and betrayal of public trust.

The March 25 hearing was the first in the committee's attempt to determine probable cause in the impeachment complaints against Duterte.
