MANILA, Philippines — Former Senate President Franklin Drilon has weighed in on the intensifying legal standoff between the Vice Presidency and the House of Representatives, calling any potential Supreme Court (SC) intervention an “interesting study” on the boundaries of judicial power.
Speaking on Sunday, April 12, 2026, during the launch of his autobiography, “Being Frank,” the veteran lawmaker and former senator-judge noted that the case would help define the limits of what the court considers a “political question.”
Drilon, who participated in two impeachment trials during his 24-year Senate career, highlighted the constitutional tension at play:
- Political vs. Legal: Impeachment is traditionally seen as a political process. Drilon noted that the current case tests how far the SC can step into this process using its power to correct “grave abuse of discretion.”
- Defining Precedent: “To what extent the Supreme Court will invoke its constitutional power… will be an interesting study for all of us,” Drilon stated. He expressed hope for a decision that will serve as a clear, generally accepted basis for the Philippine legal system.
- Separation of Powers: The case centers on whether the judiciary can halt a process that the Constitution explicitly grants to the legislative branch.
The “study” follows a significant precedent set last year when the SC first intervened in the proceedings against Vice President Sara Duterte.
- The 2025 Ruling: The high court previously declared articles of impeachment against the VP unconstitutional, citing a violation of the one-year ban rule and a lack of due process (the VP was not given a chance to present her side).
- The New Petition: With the process effectively restarting in the House, the Vice President has already filed a new petition to halt the current inquiry. As of April 13, the Supreme Court has not yet acted on this latest request.
Drilon’s comments mirror concerns raised by other legal experts, such as Paolo Tamase of the UP College of Law, who warned that premature intervention could “effectively amend impeachment out of the Constitution.” However, Drilon’s perspective as a former senator-judge adds a unique layer of insight into how the legislative and judicial branches may clash over their respective prerogatives.
The outcome of the VP’s petition is expected to set a landmark precedent for the 1987 Constitution, clarifying whether the Supreme Court acts as a final arbiter of fairness even within the walls of Congress during an impeachment.
