Case Summary (G.R. No. 174153)
COMELEC’s ruling and rationale
On 31 August 2006 COMELEC denied due course to the petition, relying on this Court’s ruling in Santiago v. COMELEC that RA 6735 was “incomplete, inadequate or wanting in essential terms and conditions” to implement initiative on amendments to the Constitution and that COMELEC was enjoined from entertaining such petitions until a sufficient enabling law was enacted. COMELEC applied Santiago and dismissed the initiative petition without making a merits determination on the sufficiency of signatures or the petition’s contents.
Parties’ positions before the Court
Petitioners sought writs of certiorari and mandamus to set aside COMELEC’s denial and compel it to give due course and call a plebiscite. They argued Santiago is not binding precedent or did not apply to them and urged that RA 6735 and COMELEC rules sufficiently implement the initiative clause. Opposing intervenors argued Santiago is binding, raised standing and verification challenges, contended the petition lacked the required form and substance (the signature sheets lacked the full text), alleged fraud and defective signature verification in many districts, argued the petition proposed a constitutional revision rather than an amendment, and invoked RA 6735’s single‑subject rule (Section 10(a)) and other defects.
Issues presented to the Court
The consolidated petitions raised three principal issues:
- Whether the Lambino Group’s petition complied with Section 2, Article XVII of the 1987 Constitution and RA 6735 (i.e., the people’s initiative requirements and how they must be satisfied in practice);
- Whether this Court should revisit Santiago v. COMELEC and the Court’s conclusion that RA 6735 is inadequate to implement initiative on constitutional amendments; and
- Whether COMELEC committed grave abuse of discretion in denying due course to the petition.
Governing constitutional standard on people’s initiative (Section 2, Article XVII)
The Court emphasized that Section 2, Article XVII allows amendments “directly proposed by the people through initiative upon a petition,” and that the Constitution’s framers expressly envisioned the people signing a petition that contains the full text of the proposed amendments (or a clearly stated attachment showing the full text). The framers’ deliberations, and comparative U.S. state jurisprudence cited by the Court, require that signatories be shown the full text before they sign so their assent is truly informed and to guard against fraud, deception and logrolling.
Full‑text and petition‑form requirement; application to the Lambino petition
The Court found as an indisputable factual and legal defect that the signature sheets submitted did not contain the full text of the proposed constitutional amendments, nor did they indicate that the full text was attached to the signature sheets. The only document showing the full proposal filed with COMELEC was not the paper that the people signed; petitioners admitted they printed only 100,000 copies of the petition text while claiming over 6.3 million signatures were collected, and could not prove wide distribution. The Court held that an initiative isValid only if signatories sign a petition that contains or incorporates the full text (either on the face or properly attached and noted), so the people have seen the full text before signing. Because the Lambino Group’s signature sheets were limited to an abstract question and omitted the text, the Court concluded the initiative did not satisfy Section 2, Article XVII’s requirement that the amendment be “directly proposed by the people through initiative upon a petition.”
Full‑text requirement: reasons, authorities, and risks (fraud/logrolling)
The Court explained rationale and supporting authorities: signatories must see the full text to make an intelligent choice, prevent fraud by promoters who might misrepresent the proposal, and prevent logrolling (combining unrelated subjects in one proposition so voters are forced to accept undesirable measures to obtain desired ones). The Lambino petition included transitory provisions authorizing the interim parliament to propose further amendments within 45 days, a provision materially unrelated to the basic institutional change; that provision looked like logrolling and further demonstrated why the people must sign a petition showing the complete text.
Amendment versus revision; qualitative and quantitative tests; application to the proposed changes
The Court reiterated the distinction between amendment and revision under Article XVII: Section 1 (Congress/Constitutional Convention) applies to “any amendment to, or revision of, this Constitution,” while Section 2 (people’s initiative) applies only to “amendments.” Drawing on comparative jurisprudence and commentary, the Court described two tests: a quantitative test (how many provisions/articles are affected) and a qualitative test (whether the basic structure/framework of government is altered). The Lambino Group’s proposal would eliminate the presidential executive and merge the legislative and executive powers into a unicameral parliament, abolish a chamber of Congress, and make sweeping structural changes. The Court held those changes are a revision — a fundamental alteration of the Constitution’s basic plan and separation of powers — and therefore outside the scope of a people’s initiative under Section 2, Article XVII.
RA 6735’s adequacy and Santiago; whether the Court should revisit Santiago
The Court explained that even assuming arguendo RA 6735 were adequate (contrary to Santiago), the Lambino petition would still be constitutionally defective for the independent reasons above (lack of full‑text petition and the petition sought a revision). Thus the Court declined to revisit Santiago because doing so would not change the outcome. The Court also reiterated the principle that courts should avoid constitutional adjudication when a case can be resolved on other grounds.
COMELEC’s denial of due course and grave abuse of discretion
Because COMELEC followed this Court’s controlling ruling in Santiago and refused to give due course, the Court held there was no grave abuse of discretion attributable to COMELEC. The Court reaffirmed that COMELEC’s action mirrored this Court’s prior decisions on the adequacy of RA 6735 and the limits on ente
Case Syllabus (G.R. No. 174153)
Case Caption and Nature of Proceedings
- En banc consolidated petitions (G.R. Nos. 174153 and 174299) filed at the Supreme Court contesting the Commission on Elections (COMELEC) Resolution dated 31 August 2006 denying due course to an initiative petition to amend the 1987 Constitution.
- Petitioners: Raul L. Lambino and Erico B. Aumentado, together with alleged 6,327,952 registered voters.
- Respondent: Commission on Elections (COMELEC).
- Reliefs sought: issuance of writs of certiorari and mandamus to set aside COMELEC Resolution and compel COMELEC to give due course to the initiative petition and call the plebiscite required by Article XVII, Sec. 4 of the Constitution.
- Intervenors and oppositors on both sides filed numerous pleadings; the Solicitor General filed a Comment supporting the petitioners’ position that RA 6735 should be treated as adequate.
Antecedent Facts — Signature Gathering and Filings
- On 15 February 2006 the Lambino group (Sigaw ng Bayan, ULAP and others) began gathering signatures nationwide for an initiative petition to change the Constitution.
- On 25 August 2006 petitioners filed a petition with COMELEC under Sections 5(b), 5(c) and 7 of Republic Act No. 6735 (Initiative and Referendum Act), alleging they secured 6,327,952 signatures (≥ 12% of registered voters) and that each legislative district was represented by at least 3% of its registered voters.
- On 30 August 2006 an Amended Petition was filed modifying proposed transitory provisions (Article XVIII).
- Petitioners claimed COMELEC election registrars had verified the signatures; they appended voluminous signature sheets and certificates to the petition submitted to COMELEC.
Petitioners’ Proposed Changes (substance of the initiative)
- Amend Sections 1–7 of Article VI (Legislative Department) and Sections 1–4 of Article VII (Executive Department).
- Add a new Article XVIII (Transitory Provisions).
- Core institutional change: shift from a bicameral-presidential system to a unicameral-parliamentary system.
- Transitory provisions: creation of an interim Parliament composed of incumbent Senators, Representatives and certain executives; provisions on terms and succession; provisions directing the interim Parliament to provide for the election of Members of Parliament, and within 45 days to convene to propose further amendments/revisions.
COMELEC Resolution (31 August 2006) — Denial of Due Course
- COMELEC denied due course to the petition for lack of an enabling law governing initiative petitions to amend the Constitution.
- COMELEC relied on Santiago v. Commission on Elections (G.R. No. 127325, March 19, 1997; Motion for Reconsideration denied June 10, 1997) which declared RA 6735 "incomplete, inadequate or wanting in essential terms and conditions insofar as initiative on amendments to the Constitution is concerned" and permanently enjoined COMELEC from entertaining petitions for initiative on constitutional amendments until Congress enacted a sufficient enabling law.
- COMELEC concluded that even if signatures appeared to meet numerical thresholds the petition could not be given due course because of Santiago.
Issues Presented to the Supreme Court
- Whether the Lambino Group’s initiative petition complied with Article XVII, Sec. 2 of the Constitution (people’s initiative requirements: ≥12% of registered voters nationwide and ≥3% in every legislative district).
- Whether the Court should revisit/reverse Santiago v. COMELEC holding RA 6735 inadequate to implement initiatives to amend the Constitution.
- Whether COMELEC committed grave abuse of discretion in denying due course to the Lambino petition.
- Ancillary factual and legal questions raised by oppositors: standing of petitioners to file on behalf of signatories; sufficiency and verification of signatures; whether the initiative embraces more than one subject (RA 6735, Sec. 10(a)); whether proposed changes constitute a revision not amendable by initiative (Art. XVII, Sec. 1–2); and compliance with RA 6735 formalities (full text requirement, attachments, abstracts).
Parties’ Main Contentions — Petitioners
- The petition is the expression of the will of the sovereign people and complies with the numerical signature thresholds.
- Santiago is not binding precedent (claimed non-majority effect) or in any event does not bar the COMELEC from acting on this petition.
- If RA 6735 is questionable, COMELEC should still give effect to the people’s will; RA 6735 and implementing rules should be treated as sufficient or as temporary devices.
- Petitioners asserted they circulated copies of the draft petition together with signature sheets and that signatures were verified by COMELEC registrars.
Parties’ Main Contentions — Oppositors / Intervenors
- Santiago is a binding precedent: COMELEC rightly followed it in dismissing the petition.
- Petitioners lacked standing/authority to file "on behalf of" the 6.3M signatories.
- Contested the validity and sufficiency of the signature-gathering and verification process: allegations of verification done by barangay officials or incomplete verification, mass rejections in some districts (e.g., Makati), allegations of forgery, withdrawals, signatures of dead or ineligible persons, minors, or multiple scribbles.
- Argued proposed changes are a revision, not an amendment, and therefore outside the scope of a people’s initiative (Art. XVII Sec. 2 limits initiative to amendments).
- Alleged petition embraces more than one subject, violating RA 6735 Sec. 10(a) (prohibition on petitions embracing more than one subject, to prevent logrolling).
Solicitor General and Supporting Intervenors
- The Solicitor General filed a Comment joining petitioners, urging that the Court grant the petition and treat RA 6735 and its implementing rules as adequate or temporarily operative to implement initiative on amendments.
- Supporting intervenors argued COMELEC committed grave abuse of discretion in relying on Santiago.
Oral Arguments and Notices on Record Evidence
- During oral argument petitioners admitted they caused printing and distribution of 100,000 copies of the petition text (February–March 2006) and asked sympathetic supporters to print additional copies; they could not confirm total distribution.
- Signature sheet reproduced in the record contained only an abstract/proposition question and space for names, addresses, birthdates and signature; it did not contain the full text of the proposed constitutional changes nor a statement that the text was attached.
- Petitioners later filed a copy of a signature sheet (exhibit) which on its face did not show the proposed constitutional text nor attach a copy; petitioners subsequently claimed privately circulated text had accompanied the signature sheets but proof of distribution to all signatories was not shown.
- Numerous election officer certifications were submitted by both sides; intervenors pointed to certifications and affidavits that alleged verification was incomplete, done ex parte, or undertaken by barangay officials.
Governing Constitutional Provision — Article XVII, Sec. 2
- Text: “Amendments to this Constitution may likewise be directly proposed by the people through initiative upon a petition of at least twelve per centum … of which every legislative district must be represented by at least three per centum of the registered voters therein. … The Congress shall provide for the implementation of the exercise of this right.”
- Constitutional Commission deliberations (quoted in the record) demonstrate that the framers intended: (a) the “draft of the proposed constitutional amendment” should be shown to signatories before they sign; and (b) the people must sign the entire proposal (petition) containing the full text (or a plainly stated attachment) — i.e., signatories must have seen the full text of the proposal before signing.
Full-Text Requirement — Legal Rationale and Foreign Analogues
- Deliberations of Constitutional Commission: framers explicitly assumed the draft would be shown to people before signing and that the people should sign the proposal itself.
- Core requirement derived: an amendment is “directly proposed by the people through initiative upon a petition” only if petition signatories sign a petition that contains or
