Case Digest: Tolentino v. COMELEC, G.R. No. L-34150, October 16, 1971
Political Law Review | The 1973 Constitution
A Constitutional Convention convened in 1971, under the 1935 Constitution, approved Organic Resolution No. 1 on September 28, 1971, proposing to lower the voting age from 21 to 18 (Section 1, Article V).
President Macapagal tasked COMELEC with conducting a plebiscite on this single amendment, coinciding with the November 8 local and senatorial elections.
Arturo Tolentino filed a petition for prohibition to stop the plebiscite, arguing that submitting one amendment separately breached the 1935 Constitution.
Organic Resolution No. 1, COMELEC’s implementing acts, and the proposed plebiscite is null and void in so far as they pertained to the separate ratification of the voting-age amendment.
All proposed amendments by a Constitutional Convention must be submitted in a single plebiscite, because Section 1, Article XV refers to submission in "an election", taken to mean only one.
Allowing piecemeal ratification would deprive voters of a complete “frame of reference”, as they could not meaningfully assess the proposed amendment in relation to the rest of the constitutional revisions.
