A member of President Rodrigo Duterte's consultative committee expressed his disappointment over the group's choice to adopt a federal-presidential form of government. 

UST political science professor Edmund Tayao said a parliamentary system would have strengthened the executive branch more since the head of the government would have the support of the majority.

"The need for a strong president does not necessarily mean you're going to retain the presidential system. I've been trying to explain that if you adopt a semi-presidential-parliamentary model, the end result could be a stronger executive," he said in an ANC interview. 

Tayao added that a federal-presidential system may only be viewed as more of the same. He said the least they can do now is to put "fail-safe" provisions to prevent the same problems from arising.
