Even before he was elected as President of the Philippines, Rodrigo Duterte is an ardent advocate of federalism. He has been firm at his vow in changing the present form of government from unitary to a federal system of government.

To change the form of government requires a change of the Constitution.

What are the ways of changing the Constitution?

Constituent Assembly (Con-Ass) and Constitutional Convention are two of the three the ways of changing the 1987 Philippine Constitution. The other way of revising/amending is through “people initiative”. There have been renewed discussions on this topic since the election of President Duterte.

What is Constituent Assembly?

The Congress, acting as a constituent assembly, directly propose the amendments or revisions by a three-fourths vote of all its members. It is not clear, however, if the Congress should vote as a single body or as separate houses.

What is Constitutional Convention?

Under this method, the Congress, by a vote of two-thirds of all its Members, call a constitutional convention. There will be a creation of a group of respected authorities to propose changes or revisions in the Constitution. It is the members of the Constitutional Convention, not the members of Congress, propose the amendments or revisions.
