August 25, 2006 – Original petition filed with COMELEC.
August 30, 2006 – Amended petition submitted.

Applicable Law

1987 Philippine Constitution, Article XVII, Section 2 (people’s initiative).
Republic Act No. 6735 (Initiative and Referendum Act).
COMELEC Resolution No. 2300 (implementing rules on initiative).

Background and Petition

Petitioners sought a COMELEC-supervised plebiscite under Section 2, Article XVII and RA 6735 to ratify amendments to Articles VI and VII and add transitory provisions (Article XVIII) for the planned shift to a parliamentary-unicameral system. They attached signature sheets they claimed represent at least 12 percent of registered voters, with 3 percent in every legislative district.

COMELEC’s Action and the Santiago Ruling

On August 31, 2006, COMELEC dismissed the petition for initiative, citing the Supreme Court’s decision in Santiago v. COMELEC, which held RA 6735 “inadequate” to implement constitutional amendments by initiative and permanently enjoined COMELEC from entertaining such petitions until Congress enacts a sufficient law.

Issues Presented

• Compliance with Section 2, Article XVII of the Constitution (12 percent/3 percent signature thresholds).
• Adequacy of RA 6735 to implement constitutional initiatives.
• Whether COMELEC abused its discretion in dismissing the petition.
• Nature of the proposed changes: amendments or revisions.

Failure to Comply with Initiative Rules

– Direct proposal requirement: Petition was filed by two individuals “as representatives,” not by the signatories themselves.
– Full-text requirement: Signature sheets did not contain or attach the complete text of proposed constitutional changes, denying signatories an informed vote.
– One-subject rule: The petition covered multiple subjects (government structure, legislative procedure, transitory provisions), violating RA 6735’s prohibition on multi-subject initiatives.

Amendments vs. Revisions

The proposed shift to a unicameral-parliamentary system would fuse legislative and executive powers, dismantling separation of powers and altering fundamental constitutional structures. Such sweeping changes constitute a revision, not a mere amendment, and thus fall outside the scope of people’s initiative under Article XVII, Section 2.

Inadequacy of RA 6735 and COMELEC’s Non-Discretionary Duty

Even if RA 6735 were upheld as adequate, petitioners failed to comply with its provisions (proper verification by election registrars, petition form and content). COMELEC’s dismissal merely followed binding precedent in Santiago and PIRMA v. COMELEC; complying with a Supreme Court en banc decisi
