A Quezon City regional trial court has dismissed a legal challenge filed by Mans Carpio, the husband of Vice President Sara Duterte, effectively clearing a significant judicial hurdle for lawmakers seeking to impeach the second-highest official in the Philippines.
The ruling, issued by Branch 81 of the Quezon City Regional Trial Court, rejected Carpio’s petition to halt the impeachment proceedings, citing a fundamental lack of jurisdiction. The court maintained that the challenge was filed in the wrong venue, asserting that any attempt to restrain the House of Representatives—a co-equal branch of government—must be elevated to the Supreme Court.
This legal setback arrives at a critical juncture for the Vice President. With the House of Representatives preparing for a plenary vote on May 11, the dismissal removes one of the primary legal barriers attempting to stall the investigation into allegations of unexplained wealth.
The core of Carpio’s petition centered on the House Committee on Justice’s authority to compel the Bureau of Internal Revenue (BIR) to release the couple’s private tax documents. Carpio argued that these subpoenas were an overreach of power; however, the court disagreed, ruling that the committee’s ability to gather evidence is an inherent and valid power necessary to fulfill its constitutional mandate.
Jurisdiction and the Co-Equal Branch Doctrine
In its decision, the court emphasized the principle of separation of powers. By ruling that the respondents were acting in their official capacity as members of the House Committee on Justice, the court noted that it could not interfere with the functions of another branch of government.
“To enjoin the public individuals in the performance of their duty in the determination of the sufficiency of the impeachment complaint is to prevent said body to exercise its quasi-judicial or ministerial functions,” the ruling stated. This suggests that the court views the impeachment process as a political and constitutional mechanism that should not be obstructed by lower regional courts.
Legal analysts suggest that by directing the petitioner toward the Supreme Court, the RTC is adhering to a strict interpretation of judicial hierarchy. In the Philippine legal system, matters involving the constitutionality of acts by high-ranking government officials or the conflict between branches of government are typically reserved for the highest court in the land.
The Battle Over Financial Records
The conflict over the Vice President’s financial history has become a focal point of the proceedings. The House Committee on Justice has been aggressively pursuing tax records to evaluate claims of unexplained wealth, which the committee has already cited as a potential impeachable offense.

The tension surrounding these documents reached a peak in March when the BIR surrendered a sealed box containing the tax records of both Sara Duterte and Mans Carpio. In a move that highlighted the legal volatility of the case, lawmakers initially decided not to open the box due to prevailing legal concerns and the pending challenges filed by the couple’s legal team.
Despite the temporary hesitation to open the records, the BIR has since launched its own audit probe into the couple’s finances. This dual-track investigation—one political and one administrative—increases the pressure on the Vice President to provide transparent accounting of her assets.
The court’s ruling reinforces the legitimacy of the subpoenas used to acquire these documents, signaling that the House Committee has the legal standing to demand financial transparency from the Vice President as part of its clarificatory hearings.
Road to May 11: The Impeachment Process
The dismissal of the plea brings the proceedings closer to a definitive vote. The House of Representatives is scheduled to conduct a plenary vote on the impeachment on May 11. This vote will determine whether the charges are sufficient to move the case forward to the Senate for trial.
Current indicators within the House suggest a strong likelihood that the Vice President will be indicted. If the plenary vote succeeds, it would mark a second time the Vice President faces such an indictment, further complicating her political standing and her relationship with the current administration.
| Phase | Action/Event | Status/Date |
|---|---|---|
| Evidence Gathering | BIR surrenders sealed tax records to House | March (Completed) |
| Legal Challenge | Mans Carpio files plea to stop proceedings | Dismissed by QC RTC |
| Committee Report | Unexplained wealth cited as impeachable offense | Adopted |
| Final House Action | Plenary vote on impeachment | Scheduled: May 11 |
The stakes of the May 11 vote extend beyond the legalities of tax records. An impeachment indictment would trigger a trial in the Senate, where the Vice President would have to defend her record and financial disclosures before a body of her peers. This process often leads to significant political realignment and can result in removal from office if the required two-thirds majority is met.

For now, the Vice President’s camp faces a narrowing window of legal options. With the regional court refusing to intervene, any further attempts to block the proceedings will likely require a high-stakes petition to the Supreme Court, which must then decide whether to grant a temporary restraining order (TRO) before the May 11 deadline.
