Amendment and revision are foundational concepts in constitutional change under the 1987 Philippine Constitution. Mastery of their distinction, modes, and limitations is essential for Bar essays, which often test whether a proposed change qualifies as an amendment (via people's initiative) or a revision (requiring constituent assembly or convention), alongside procedural compliance and ratification requirements.
Core Legal Basis and Definition
Article XVII of the 1987 Constitution governs amendments or revisions.
Section 1. Any amendment to, or revision of, this Constitution may be proposed by: (1) The Congress, upon a vote of three-fourths of all its Members; or (2) A constitutional convention.
Section 2. Amendments to this Constitution may likewise be directly proposed by the people through initiative upon a petition of at least twelve per centum of the total number of registered voters, of which every legislative district must be represented by at least three per centum of the registered voters therein. No amendment under this section shall be authorized within five years following the ratification of this Constitution nor oftener than once every five years thereafter.
- Amendment refers to a change that adds, reduces, or deletes provisions without altering the basic principles of the Constitution. It affects specific provisions and improves or carries out the original purpose.
- Revision broadly implies a change that alters basic principles (e.g., form of government, separation of powers) or affects the substantial entirety of the Constitution.
Essential Requisites and Modes
Modes for Proposing Changes (Section 1)
- Congress as Constituent Assembly — Requires a vote of three-fourths of all its Members. Houses vote separately due to bicameral nature.
- Constitutional Convention — Congress may call it by a vote of two-thirds of all its Members, or submit the question to the electorate by a majority vote of all its Members (Section 3).
People's Initiative (Section 2)
- Limited to amendments only (not revisions).
- Requires: (a) petition of at least 12% of total registered voters; (b) at least 3% in every legislative district.
- Subject to 5-year ban after ratification and frequency limit.
Ratification (Section 4): Any amendment or revision becomes valid when ratified by a majority of votes cast in a plebiscite held not earlier than 60 days nor later than 90 days after approval.
Landmark Supreme Court Doctrines
Lambino v. COMELEC (G.R. No. 174153, October 25, 2006): People's initiative is limited to amendments, not revisions. A shift from bicameral-presidential to unicameral-parliamentary system constitutes a revision. The initiative petition must contain the full text of the proposed amendments. The two-part test (quantitative and qualitative) determines amendment vs. revision.
Santiago v. COMELEC (G.R. No. 127325, March 19, 1997): RA 6735 (Initiative and Referendum Act) is inadequate as an enabling law for people's initiative on constitutional amendments.
Key Exceptions, Qualifications, and Distinctions
Distinction between Amendment and Revision (Lambino doctrine):
| Aspect | Amendment | Revision |
|---|---|---|
| Scope | Specific provision(s) | Substantial or basic principles |
| Quantitative Test | Fewer provisions affected | Many provisions affected |
| Qualitative Test | No change in basic governmental plan | Alters nature of government structure |
| People's Initiative | Allowed | Not allowed |
| Typical Examples | Term limits, specific rights | Change to parliamentary system, abolition of Senate |
- Revision requires more deliberative processes (ConAss or ConCon) due to its fundamental impact.
- Congress acting as Constituent Assembly exercises constituent power, not legislative power.
- No judicially imposed limits on the substance of amendments/revisions, but procedural requirements are strictly enforced.
Common Pitfalls:
- Confusing the voting requirement in Congress (3/4 for proposal vs. separate voting).
- Assuming people's initiative can cover revisions.
- Failing to distinguish from ordinary statutory amendments.
How This Topic Appears in Bar Essay Questions
Examiners typically present a factual scenario involving a proposed change (e.g., people's initiative for economic provisions or shift in government form) and ask:
- Whether it is an amendment or revision.
- Validity of the mode used.
- Compliance with requisites.
- Effect if ratified or not.
Best Answer Structure:
- State the rule (cite Article XVII, Sections 1-4).
- Define and distinguish amendment vs. revision (cite Lambino).
- Apply the two-part test to facts.
- Check procedural compliance (signatures, full text, timing).
- Conclude on validity and ratification requirements.
Practical Application Tips
- Memory Aid: "A for Addition/specific (Amendment); R for Radical change (Revision)."
- Always start with: "Under Article XVII, Section 1..." for proposals and "Section 2..." for initiatives.
- In essays, emphasize that while the people are sovereign, constitutional change must follow explicit procedures to prevent chaos.
Key Takeaways
- People's initiative is strictly for amendments only; revisions need ConAss or ConCon.
- Use the quantitative + qualitative test from Lambino to classify changes.
- Strict compliance with signature requirements, full text disclosure, and ratification plebiscite is mandatory.
- The 5-year restriction applies only to people's initiative.
- Congress proposes via 3/4 vote; convention via 2/3 or majority referral.
- Ratification by majority in plebiscite is the final step for validity.
