Constitutional law expert and former Integrated Bar of the Philippines (IBP) president Domingo Cayosa has expressed support for a Constitutional Convention (Con-Con) to amend certain provisions of the 1987 Constitution — but with important safeguards in place.

In a radio interview on Wednesday, Cayosa said, “It’s normal to improve the Constitution. The best thing is a Constitutional Convention with the participation of the people.”

Cayosa, however, warned the process may be compromised if just anyone without qualifications is allowed to run for Con-Con delegate, potentially letting in political dynasties and celebrity candidates.

“What we fear is that anyone would be allowed to run, then we will be back to dynasties and artists,” he said.

Cayosa suggested setting minimum requirements for eligibility. He said delegates should possess the necessary legal and governance know-how, experience in government or industry, and a clear understanding of the Constitution’s principles.

He added that revising the Constitution would be easier and more meaningful if those tasked with the job had no vested interests.

“It is crucial that those making the changes are not driven by self-interest,” Cayosa emphasized.

Earlier, President Ferdinand R. Marcos Jr. said he supports a Constitutional Convention if its purpose is to address ambiguities in the 1987 Charter.

He said the goal should be to enhance and clarify provisions so no part of the Constitution is violated.

His remarks came after Deputy Speaker and National Unity Party chairperson Ronaldo Puno on Monday called for a Con-Con to conduct a comprehensive review of the Constitution, address its vague provisions, and introduce needed reforms.

Puno said his proposal is not for discarding the Charter but to “complete and correct it,” adding that a Con-Con would ensure a “singularity of purpose.”

Meanwhile, Palace spokesperson Claire Castro clarified that the President had no firm stance on the matter until the full details of the proposal are released.

Still, she acknowledged that some provisions of the Constitution were ambiguous, sometimes favoring certain individuals.

“In such cases, we will know what the framers of the 1987 Constitution truly intended,” Castro said.

A Con-Con is one of three methods for amending the Charter. Under this setup, delegates elected by the people from each district will review and propose constitutional changes. The two other methods are a Constituent Assembly and a people’s initiative.
