The impeachment trial of Philippine Vice President Sara Duterte has reached a critical stage, with recent hearings highlighting potential conflicts of interest and unexplained financial movements. Testimony from the Securities and Exchange Commission (SEC) suggests that Duterte and her husband, Manases Carpio, maintained ties to 18 different corporations throughout her time in office. Under the 1987 Philippine Constitution, public officials are strictly prohibited from holding business interests that could create conflicts, yet SEC records indicate that the Vice President remained listed as a stockholder and board member well into 2025. Adding to the scrutiny, government procurement data revealed that GenCorp Industries—a firm linked to Duterte—secured numerous state contracts, including several from the Davao City government currently led by her brother, Sebastian Duterte.

The prosecution team is utilizing this data to build a case centered on allegations of unexplained wealth and the filing of inaccurate Statements of Assets, Liabilities, and Net Worth (SALN). Prosecutors point to records from the Anti-Money Laundering Council showing that roughly P6.77 billion in financial activity passed through accounts associated with the couple over nearly two decades, a figure that far exceeds her declared net worth. While Duterte’s defense team has dismissed these claims as speculative and politically motivated, the Senate is now preparing to determine the voting threshold required for a potential conviction. As the proceedings move toward a final vote, the core debate remains whether these corporate ties and financial flows constitute a violation of the constitutional ban on public officials engaging in private business.
