Constitutional revision – contemplates a re-writing of the entire Constitution or a major portion thereof, such as a change in the form of government from presidential to parliamentary or the replacement of the present bicameral Congress with a unicameral legislature. (see Philippine Constitutional Law, vol. 2, p. 1161 ).
Any amendment to, or revision of, this Constitution may be proposed by: (1) The Congress, upon a vote of three-fourth of all its Members; or (2) A constitutional convention. (Constitution, Art. XVII, Section 1)
Unlike the 1935 Constitution which expressly provides that the Senate and the House of Representatives, voting separately, may propose amendments or revisions to the Constitution, the present Constitution does not state how the vote of all the members of Congress should be determined. (see Philippine Constitutional Law, vol. 2, p. 1163 ).
Can 200 members of the House of Representative (out of 250 members), together with 5 senators (out of 24 senators), validly propose amendments or revisions to the Constitution?
