The 1987 Constitution of the Republic of the Philippines — An Article-by-Article Guide
When you think about doing business, investing, relocating or handling legal matters in the Philippines, this Constitution is the wall you eventually run into. The 60/40 foreign ownership limits, the fact that foreigners cannot buy land, the absence of a divorce law, the fact that a president cannot be re-elected — all of these are written not in statutes but in the text of the Constitution. This guide sets out the whole of the Preamble plus 18 Articles, checking the article and section numbers against the original.
The texts relied on: the full text of the 1987 Constitution as carried in the LawPhil Project (Arellano Law Foundation), cross-checked against the full-text PDF (53 pages) held by the University of Minnesota Human Rights Library. Article and section numbers and wording have been verified against the originals. Re-verification of 2026-08-26: Articles XII, XIII and XVII were collated section by section against the original text in full (the complete LawPhil HTML plus a 42-page PDF held by the ICJ, fully extracted with a PDF text extractor), and the main provisions of Articles II, III, VI–XI, XIV, XVI and XVIII were re-checked. 注Use the LawPhil version to fix wording (the ICJ PDF contains scattered transcription errors such as "The Sate shall," "technical of financial assistance," and "communal" → "local" in Article XIII, Section 7). For the full list of corrections see "Verification record (2026-08-26)" at the end.
注This file is the representative file for the four institutional documents (The 1987 Constitution / Agrarian Reform and CARP / Poverty and Social Security / The Japan–Philippines Economic Relationship in Detail), and the verification records for all four are consolidated at the end.
1. How it came about — February 1986 to February 1987
| Date | Event | Primary source |
|---|---|---|
| 1986-03-25 | President Aquino issued Proclamation No. 3 (the "Freedom Constitution"), provisionally adopting only the 1973 Constitution's provisions on national territory, citizenship, the bill of rights and suffrage, and provisionally vesting legislative power in the President | Proclamation No. 3, s.1986 (LawPhil) |
| 1986-04-23 | Proclamation No. 9 created the Constitutional Commission (ConCom). Its members were "not more than fifty national, regional and sectoral representatives," with the work targeted for completion by 2 September 1986 | Proclamation No. 9, s.1986 (LawPhil) |
| 1986-10-12 | The ConCom approved the draft | The certification at the end of the constitutional text (placed immediately after Article XVIII, Section 27: "The foregoing proposed Constitution … was approved by the Constitutional Commission of 1986 on the twelfth day of October, Nineteen hundred and eighty-six…"). 注(Corrected in the 2026-08-26 verification. Article XVIII, Section 27 contains only the effectivity provision; the record of approval and signing is not in that section but in the closing certification. Source: LawPhil consti/cons1987.html) |
| 1986-10-15 | The members signed in the Plenary Hall of the National Government Center, Quezon City | Same as above ("accordingly signed on the fifteenth day of October, Nineteen hundred and eighty-six at the Plenary Hall, National Government Center, Quezon City") |
| 1987-02-02 | The plebiscite. Yes 16,622,111 / No 4,953,375 / abstentions 209,730; total votes cast 21,785,216 (83,288 precincts) | Proclamation No. 58, s.1987 (the LawPhil text. Abstentions and the total added in the 2026-08-26 verification) |
| 1987-02-11 | President Aquino signed Proclamation No. 58 and declared ratification | Same as above |
注When you give an approval percentage, always state the denominator (the indicator) (added in the 2026-08-26 verification). - As a share of valid votes (yes + no = 21,575,486): 77.04% - As a share of total votes cast (21,785,216, including the 209,730 abstentions): 76.30% (Both computed by the author from the COMELEC tallies given in Proclamation No. 58. The "about 77.0%" of the earlier version is the first indicator.)
注 Easily got wrong ①: is the date of effectivity 2 February or 11 February?
- The original text of Article XVIII, Section 27 reads: "This Constitution shall take effect immediately upon its ratification by a majority of the votes cast in a plebiscite held for the purpose and shall supersede all previous Constitutions."
- Proclamation No. 58, on the other hand, is dated 11 February 1987. For this reason Japanese-language material often says "effective 11 February."
- In De Leon v. Esguerra (G.R. No. L-78059, 31 August 1987, En Banc, Gutierrez, Jr., J.), the Supreme Court quoted Article XVIII, Section 27 and stated explicitly that "The 1987 Constitution was ratified in a plebiscite on February 2, 1987. By that date, therefore, the Provisional Constitution must be deemed to have been superseded." — i.e. the date of effectivity is the date of the plebiscite, 2 February 1987.
- 注(Corrected in the 2026-08-26 verification. The earlier version gave "G.R. No. 78059, 31 August 1988" and marked it "注primary source not reached," but the correct citation is G.R. No. L-78059, 31 August 1987, and the text of the decision was reached. Source: LawPhil
judjuris/juri1987/aug1987/gr_l-78059_1987.html) - The case concerned the validity of an OIC governor's designation, dated 8 February 1987 under the Provisional (Freedom) Constitution, of replacements for barangay officials. The Court held that by that date the 1987 Constitution was already in force and the Provisional Constitution had lapsed, and so voided the designation.
- Accordingly, both the text and the case law make the date of effectivity 2 February 1987; 11 February is merely the date of Proclamation No. 58, the declaration of ratification. The "effective 11 February" of Japanese-language material is wrong.
2. The overall structure — a Preamble plus 18 Articles
| Article | Title (original) | Main content |
|---|---|---|
| Preamble | Preamble | "We, the sovereign Filipino people, imploring the aid of Almighty God…" = popular sovereignty and an invocation of God |
| I | National Territory | The archipelago and its internal waters, and the areas over which sovereignty and jurisdiction extend |
| II | Declaration of Principles and State Policies | The national creed. Sections 1–6 are "principles," Sections 7–28 "state policies" |
| III | Bill of Rights | The bill of rights (22 sections) |
| IV | Citizenship | Citizenship |
| V | Suffrage | The right to vote |
| VI | The Legislative Department | The legislature (both chambers) |
| VII | Executive Department | The executive (the President) |
| VIII | Judicial Department | The judiciary (the Supreme Court) |
| IX | Constitutional Commissions | CSC, COMELEC, COA |
| X | Local Government | Local autonomy and autonomous regions |
| XI | Accountability of Public Officers | Accountability of officials, impeachment, the Ombudsman |
| XII | National Economy and Patrimony | The heart of foreign ownership restrictions |
| XIII | Social Justice and Human Rights | Agrarian reform, labor, the CHR |
| XIV | Education, Science and Technology, Arts, Culture and Sports | Education and language |
| XV | The Family | The family |
| XVI | General Provisions | The flag, the armed forces, media ownership and so on |
| XVII | Amendments or Revisions | Procedures for amendment |
| XVIII | Transitory Provisions | Transitory provisions (27 sections) |
注 Article XIV is sometimes given as "Education, Culture, Science and Technology," but the original is "EDUCATION, SCIENCE AND TECHNOLOGY, ARTS, CULTURE AND SPORTS."
3. Article II — the Declaration of Principles and State Policies
The six "Principles" are the skeleton of the state.
| Section | Content (the gist of the original) |
|---|---|
| 1 | "The Philippines is a democratic and republican State. Sovereignty resides in the people" |
| 2 | Renunciation of war; adoption of "the generally accepted principles of international law" as part of the law of the land |
| 3 | "Civilian authority is, at all times, supreme over the military." The armed forces are "the protector of the people and the State" |
| 4 | The prime duty of the government is to serve and protect the people. Under conditions provided by law, citizens may be required to render personal military or civil service |
| 5 | The maintenance of peace and order, the protection of life, liberty and property, and the promotion of the general welfare |
| 6 | "The separation of Church and State shall be inviolable" |
The "State Policies" most often cited in practice:
- Section 8: a policy of freedom from nuclear weapons
- Section 12: "protect the life of the mother and the life of the unborn from conception" — the constitutional ground on which abortion is not legalized
- Section 16: the right to a balanced and healthful ecology — the provision underpinning environmental litigation since the Oposa case
- Section 19: "a self-reliant and independent national economy effectively controlled by Filipinos"
- Section 26: the State "shall prohibit political dynasties as may be defined by law"
- Section 28: a policy of full public disclosure
The biggest development of 2026 — the anti-political dynasty bill
Article II, Section 26 is a provision requiring an implementing statute ("as may be defined by law"), and for 39 years since 1987 no such statute had been enacted. On 3 June 2026 the House of Representatives was reported to have passed an anti-political dynasty bill on third reading by 267 to 20 (7 abstentions) (Philippine News Agency / BusinessWorld / GMA, all 2026-06-03). The bicameral conference with the Senate version is expected to be difficult (Inquirer.net, 2026-06-29). 注 As of 2026-08-26 it has not been enacted.
4. Article III, the Bill of Rights — 22 sections
| Section | What is guaranteed |
|---|---|
| 1 and 22 | Due process and the equal protection of the laws / the prohibition of ex post facto laws and bills of attainder |
| 2 and 3 | The prohibition of unreasonable searches and seizures (a warrant requires a judge personally to determine probable cause after examination under oath), the privacy of communication, and the express exclusionary rule for illegally obtained evidence |
| 4, 5 and 8 | Freedom of speech, expression and the press, and the rights of assembly and petition / the prohibition of an established religion, freedom of religion, and the prohibition of religious tests / the right to form associations and unions, in the public and private sectors alike |
| 6 | Liberty of abode and of travel (restrictions only in the interest of national security, public safety or public health) |
| 7 | The right of access to information on matters of public concern |
| 9, 10 and 11 | The prohibition of taking without just compensation / the prohibition of laws impairing the obligation of contracts / the prohibition of denying access to the courts by reason of poverty |
| 12–14, 16, 17, 21 | The rights of the accused (the Philippine Miranda: notification of the right to remain silent and to counsel), the right to bail (except where the offense is punishable by reclusion perpetua and the evidence of guilt is strong), the presumption of innocence, the right to a speedy disposition of cases, the privilege against self-incrimination, and the prohibition of double jeopardy |
| 15 and 18 | The writ of habeas corpus may be suspended only in cases of invasion or rebellion / the prohibition of detention solely by reason of political beliefs, and the prohibition of involuntary servitude |
| 19 | The prohibition of cruel punishment. "Neither shall death penalty be imposed, unless, for compelling reasons involving heinous crimes, the Congress hereafter provides for it" = a conditional prohibition, not an absolute one |
| 20 | The prohibition of imprisonment for debt or non-payment of a poll tax |
注 Section 19 is often simplified to "the Constitution abolished the death penalty," but the text leaves room for Congress to restore it for heinous crimes. That structure is why it was in fact restored in 1993 and abolished again in 2006.
5. Article IV, Citizenship / Article V, Suffrage
Article IV (Citizenship) - Section 1: ① those who were citizens at the time of the Constitution's adoption; ② those whose fathers or mothers are citizens of the Philippines (jus sanguinis through either parent); ③ those born before 17 January 1973 of Filipino mothers who elect Philippine citizenship on reaching the age of majority; ④ those naturalized. - Section 2: "natural-born citizens" are those who are citizens from birth without having to perform any act to acquire or perfect their citizenship. The President, Vice-President, members of both chambers, Justices of the Supreme Court, members of the constitutional commissions, the Ombudsman and others all carry a natural-born requirement. - Section 4: Filipinos who marry aliens retain their citizenship. - Section 5: "Dual allegiance of citizens is inimical to the national interest and shall be dealt with by law." 注 Note that this is not a prohibition of dual citizenship as such (the reacquisition regime under RA 9225 rests on this reading).
Article V (Suffrage) - Section 1: Age 18 and over, resident of the Philippines for at least one year and of the place where they propose to vote for at least six months. No literacy, property or other substantive requirement may be imposed. - Section 2: Congress shall provide a system for absentee voting by Filipinos abroad, and procedures for voters with disabilities and illiterates.
6. Articles VI–VIII — the three branches
| Item | Provision | Content |
|---|---|---|
| Senate | Art. VI, Secs. 2 and 4 | 24 members elected at large, six-year terms, no more than two consecutive terms |
| House | Art. VI, Secs. 5 and 7 | "Not more than two hundred and fifty members, unless otherwise fixed by law." Three-year terms, no more than three consecutive terms |
| Party-list | Art. VI, Sec. 5(2) | Party-list representatives constitute 20% of the total membership |
| Election day | Art. VI, Sec. 8 | The second Monday of May |
| President | Art. VII, Secs. 2 and 4 | At least 40 years old, natural-born, resident for at least ten years. A six-year term, no re-election whatsoever ("shall not be eligible for any re-election") |
| Vice-President | Art. VII, Secs. 3 and 4 | The same qualifications and term as the President. No more than two consecutive terms. May be appointed to the Cabinet without need of confirmation |
| Martial law | Art. VII, Sec. 18 | Not exceeding 60 days. Report to Congress within 48 hours. A majority of both houses voting jointly may revoke it (the President cannot set that aside). On a citizen's petition, the Supreme Court reviews the sufficiency of the factual basis and must decide within 30 days |
| Judicial power | Art. VIII, Sec. 1 | "Judicial power includes the duty … to determine whether or not there has been a grave abuse of discretion amounting to lack or excess of jurisdiction on the part of any branch or instrumentality of the Government" = the great invention of the 1987 Constitution. It shuts down the political-question doctrine and vastly expands judicial review |
| Supreme Court | Art. VIII, Secs. 3 and 4 | A Chief Justice and 14 Associate Justices, 15 in all. Fiscal autonomy (its appropriation may not be reduced below the previous year's). It sits en banc and in divisions of three, five or seven |
7. Article IX — the Constitutional Commissions
Article IX-A, Section 1: "The Constitutional Commissions, which shall be independent, are the Civil Service Commission (CSC), the Commission on Elections (COMELEC), and the Commission on Audit (COA)."
| Commission | Composition | Term | Basis |
|---|---|---|---|
| CSC | A chairman and two commissioners (three) | Seven years, without reappointment | Art. IX-B, Sec. 1 |
| COMELEC | A chairman and six commissioners (seven) | Seven years, without reappointment | Art. IX-C, Sec. 1 |
| COA | A chairman and two commissioners (three) | Seven years, without reappointment | Art. IX-D, Sec. 1 |
Common provisions (Article IX-A): - Section 2: an absolute prohibition on holding other office, engaging in business, or having a financial interest in government contracts while in office - Section 5: fiscal autonomy (approved annual appropriations are automatically and regularly released) - Section 7: each Commission decides by majority vote within 60 days of submission. A party aggrieved by a decision may bring certiorari to the Supreme Court within 30 days of receipt
注 All three have "seven-year terms without reappointment, including the chairman," but there is a staggering provision under which the first appointees serve seven, five and three years respectively.
8. Article X — local government and autonomous regions
- Section 1: The territorial and political subdivisions are provinces, cities, municipalities and barangays. In addition, "there shall be autonomous regions in Muslim Mindanao and the Cordilleras."
- Section 3: a duty to enact a Local Government Code → RA 7160 (1991).
- Section 6: "Local government units shall have a just share, as determined by law, in the national taxes which shall be automatically released to them." 注 The original says "national taxes," not "internal revenue taxes." The Supreme Court's Mandanas ruling (2018, final in 2019) relied on that wording to order an allotment including customs duties (the NTA = National Tax Allotment).
- Section 8: terms of local elective officials are three years, no more than three consecutive terms (barangay officials excepted).
- Section 10: the creation, division, merger or alteration of boundaries of an LGU requires approval by a majority of the votes cast in a plebiscite in the political units directly affected.
- Section 18: an autonomous region includes only those constituent units that vote in favor in the plebiscite ("only provinces, cities, and geographic areas voting favorably … shall be included in the autonomous region").
- Section 19: the first Congress under the Constitution is obliged to pass the organic acts for both autonomous regions within 18 months of its organization.
- Section 20: nine areas of legislative power for the autonomous regional assemblies (administrative organization, sources of revenue, ancestral domain and natural resources, personal, family and property relations, regional planning, economic, social and tourism development, educational policies, cultural heritage, and other matters).
- Section 21: the preservation of peace and order rests with the regional police force, and national defense and security with the national government.
8-1. Muslim Mindanao — from ARMM to BARMM
| Year | Item | Source |
|---|---|---|
| 1989 | RA 6734 (the ARMM Organic Act) enacted | — |
| 2001 | RA 9054 (amending the ARMM Organic Act) | — |
| 2018-07-23 | RA 11054 (the Bangsamoro Organic Law) enacted, repealing RA 6734 (as amended by RA 9054) and creating BARMM | The text of RA 11054 (LawPhil) |
| 2019 | BARMM was established by plebiscite, governed by the interim Bangsamoro Transition Authority (BTA) | — |
| 2026-03-25 | RA 12317 enacted (corrected in the 2026-08-26 verification; the earlier version gave "2026-03-24," but the date in the original text is [ REPUBLIC ACT NO. 12317, March 25, 2026 ]. Sources: the text of RA 12317 in the Supreme Court E-Library / Manila Bulletin, 27 March 2026, p.7, as an alternative to Official Gazette publication). It again amended Article XVI, Section 13 of RA 11054 (注writing "Section 16, Article 13" reverses article and section. The amending law is RA 12317, Section 1; what is amended is RA 11054, Art. XVI, Sec. 13. The earlier amendments were RA 11593 〈2021-10-29〉 and RA 12123 〈2025-02-19〉, both amending the same Art. XVI, Sec. 13), providing that "The first regular election for the Bangsamoro Government under this Organic Law shall be held on the second Monday of September 2026." Section 6 of the same law sets the term of those first elected from noon of 30 October 2026 to noon of 30 June 2031, and synchronizes subsequent regular elections with the national and local elections every three years from the second Monday of May 2031 | The text of RA 12317 (Supreme Court E-Library) |
| 2026-09-14 | The scheduled date of the first BARMM parliamentary election. The government was reported to have declared it a special holiday in BARMM (PNA / Philstar / GMA, all 2026-08-21) | Press reports |
注 The BARMM parliamentary election was originally to be held with the May 2025 midterms, but after several postponement statutes it became 14 September 2026. As of the writing of this document (2026-08-26) it has not yet been held; there were reports of renewed calls for postponement after a security incident (the attack on Mr. Macacua), but COMELEC and the Office of the President are said to be proceeding as scheduled (Philstar / Daily Tribune, 2026-08-17).
8-2. The Cordilleras — an autonomous region that has not materialized in 39 years
- 1989: RA 6766 enacted → in the plebiscite of 30 January 1990 only Ifugao voted in favor (by a margin of 5,889 votes); the other provinces and Baguio City rejected it by a combined margin of 148,676. 注The areas covered at that time were the five provinces of Benguet, Mountain Province, Ifugao, Abra and Kalinga-Apayao (then a single province), plus Baguio City (added in the 2026-08-26 verification. Source: the findings of fact in the Ordillo decision — "approved by a majority of 5,889 votes in only the Ifugao Province and was overwhelmingly rejected by 148,676 votes in the rest of the provinces and city"). COMELEC declared the approval by Ifugao alone in Resolution No. 2259 of 14 February 1990.
- The Supreme Court in Ordillo v. COMELEC (G.R. No. 93054, 4 December 1990): "a single province cannot validly constitute the Cordillera Autonomous Region." It relied on the plural forms in Article X, Section 15 — "provinces, cities, municipalities and geographical areas" (the text of the decision on LawPhil).
- 22 December 1997: RA 8438 ("AN ACT TO ESTABLISH THE CORDILLERA AUTONOMOUS REGION") enacted. Under Article XV (Transitory Provisions), Section 11, a plebiscite was to be held 45 to 120 days after approval of the law (注corrected in the 2026-08-26 verification. The earlier version wrote "Section 15, Article 11," but RA 8438 is an organic act in 16 Articles, and the article and section were reversed. The rule this document itself laid down for RA 11054 and RA 12317 — do not confuse Article with Section — applies equally to RA 8438. Source: LawPhil
ra_8438_1997.html). The area covered by the plebiscite is defined in Article I, Section 2(b) as the six provinces of Benguet, Mountain Province, Ifugao, Abra, Kalinga and Apayao, plus Baguio City (the increase from five provinces in 1990 to six is because RA 7878 〈approved 14 February 1995〉 converted the sub-provinces of Kalinga and Apayao into regular provinces. Source: the title of RA 7878 on LawPhil). The same section appropriated ₱80 million for the plebiscite and related costs. 注 This second plebiscite is also said to have been rejected, but the primary source for the result (a COMELEC resolution or the like) could not be reached. - On 3 August 2026, Cordillera regional leaders were reported to have sought the President's support for a new autonomy bill (Philippine News Agency, 2026-08-03). The Cordillera Autonomous Region still does not exist as of August 2026, and CAR (the Cordillera Administrative Region) remains an administrative division only.
9. Article XI — accountability of public officers and impeachment
Section 1: "Public office is a public trust."
Who may be impeached and on what grounds (Section 2)
| Subject | Grounds |
|---|---|
| The President, the Vice-President, the Members of the Supreme Court, the Members of the Constitutional Commissions (CSC, COMELEC, COA), and the Ombudsman | Culpable violation of the Constitution, treason, bribery, graft and corruption, other high crimes, and betrayal of public trust |
注 These five categories only are impeachable (① the President, ② the Vice-President, ③ Justices of the Supreme Court, ④ members of the Constitutional Commissions, ⑤ the Ombudsman). (Corrected in the 2026-08-26 verification. The earlier version said "six categories," but the original text of Article XI, Section 2 enumerates five classes of office: "The President, Vice-President, the Members of the Supreme Court, the Members of the Constitutional Commissions, and the Ombudsman." Counting CSC, COMELEC and COA separately would give seven, but the text's unit of enumeration is "the Members of the Constitutional Commissions," which is one. Source: the text of the 1987 Constitution on LawPhil.) The text goes on to state: "All other public officers and employees may be removed from office as provided by law, but not by impeachment." Cabinet members and legislators are not impeachable.
Procedure (Section 3)
| Stage | Requirement |
|---|---|
| Initiation | The House of Representatives has "the exclusive power to initiate all cases of impeachment" |
| Complaint | A verified complaint filed by a Member of the House, or by a citizen upon a resolution of endorsement by any Member |
| Calendar | Included in the Order of Business within ten session days, and referred to the proper Committee within three session days thereafter |
| Committee | A report within 60 session days of referral. The House calendars it for consideration within ten session days of receipt |
| Plenary | The Articles of Impeachment are affirmed by at least one-third of all Members of the House |
| Shortcut route | If a verified complaint or resolution is filed by at least one-third of all Members, it constitutes the Articles of Impeachment, and trial by the Senate shall forthwith proceed |
| The one-year rule | "No impeachment proceedings shall be initiated against the same official more than once within a period of one year" (Section 3(5)) |
| Senate | The Senate has the sole power to try and decide. When the President is on trial, the Chief Justice presides (without a vote). Conviction requires two-thirds of all Members of the Senate |
| Effect | Removal from office and disqualification to hold any office. The party convicted remains liable to criminal prosecution |
2025–2026 — the impeachment of Vice-President Sara Duterte
- In February 2025 the House transmitted articles of impeachment against the Vice-President to the Senate.
- In Sara Z. Duterte v. House of Representatives (G.R. Nos. 278353 / 278359) the Supreme Court ruled on 25 July 2025 and rendered its final determination on 29 January 2026. The 2025 articles of impeachment were held unconstitutional and void as a violation of the one-year rule in Article XI, Section 3(5) and of due process (the list of the decision and separate opinions on the Supreme Court website, 2025-07-25 / 2026-01-29. The full text PDF of the decision could not be reached). Reporting describes it as "in conflict with the one-year bar, and without due process" (Inquirer.net, 2025-07-26 / ABS-CBN and Rappler, 2026-01-29–30).
- A fresh impeachment complaint was then filed with the House in February 2026; on 11 May 2026 the House passed new articles of impeachment by 257 votes, transmitting them to the Senate on 13 May; the Senate convened as an impeachment court on 18 May; and the impeachment trial opened on 6 July 2026 (Inquirer.net / SunStar / Philstar / PNA, reports from May to July 2026).
- As of 25 August 2026 the trial had reached its 18th day, with the use of the Office of the Vice-President's confidential funds (about ₱125 million) as the issue (ABS-CBN / Philstar, 2026-08-25). The impeachment court is reported to be aiming to conclude within the year.
- 注 The claim that "the Supreme Court held the impeachment unconstitutional" refers to the ruling on the 2025 articles and is a separate matter from the 2026 trial (VERA Files fact check, 2026-06-24).
Other important provisions of Article XI: the Sandiganbayan (the anti-graft court, Section 4); the Ombudsman (Tanodbayan, Sections 5–14; a seven-year term without reappointment, with fiscal autonomy); the right to recover ill-gotten wealth is not barred by prescription (Section 15); the prohibition of loans from government financial institutions to high officials (Section 16); and the sworn statement of assets, liabilities and net worth = SALN (Section 17).
10. Article XII — National Economy and Patrimony (the heart of foreign ownership restrictions)
10-1. Section 2 — the Regalian Doctrine
The opening of the original text: "All lands of the public domain, waters, minerals, coal, petroleum, and other mineral oils, all forces of potential energy, fisheries, forests or timber, wildlife, flora and fauna, and other natural resources are owned by the State."
| Issue | What the text provides |
|---|---|
| State ownership | All natural resources — lands of the public domain, waters, minerals, coal, petroleum, potential energy, fisheries, forests, wildlife and the rest — are owned by the State |
| Inalienability | With the exception of agricultural lands, natural resources shall not be alienated |
| Modes of development | The State may undertake it directly, or enter into co-production, joint venture or production-sharing agreements with Filipino citizens, or corporations at least 60% of whose capital is owned by Filipino citizens |
| Duration | 25 years, renewable for not more than 25 years |
| Marine resources | The use of marine wealth in the archipelagic waters, territorial sea and EEZ is reserved exclusively to Filipino citizens |
| The foreign-capital exception | The President may enter into agreements with wholly foreign-owned corporations involving "either technical or financial assistance" (FTAAs) for large-scale exploration and development of minerals, petroleum and the like. Congress must be notified within 30 days of execution |
In La Bugal-B'laan Tribal Association v. Ramos (G.R. No. 127882, 1 December 2004) the Supreme Court read the fourth paragraph's "agreements involving either technical or financial assistance" as including service contracts with appropriate safeguards, and upheld the Mining Act (RA 7942) and its implementing rules as constitutional (the decision on LawPhil). 注 Note that this was a decision on reconsideration reversing the original ruling of January 2004.
10-2. Section 3 — classification of public lands and area ceilings
Lands of the public domain are classified into agricultural, forest or timber, mineral lands, and national parks. Only agricultural lands are alienable.
| Holder | Ceiling on acquisition or lease |
|---|---|
| Private corporations or associations | Lease only. 25 years (renewable for 25), not exceeding 1,000 ha |
| Filipino citizens | Lease of not more than 500 ha; acquisition by purchase, homestead or grant of not more than 12 ha |
10-3. Section 7 — the prohibition on land ownership by foreigners
The original: "Save in cases of hereditary succession, no private lands shall be transferred or conveyed except to individuals, corporations, or associations qualified to acquire or hold lands of the public domain."
- = Except by inheritance, private land may be transferred only to those qualified to acquire or hold lands of the public domain (Filipino citizens, and corporations at least 60% Filipino-owned). This is the constitutional basis of "foreigners cannot buy land in the Philippines."
- Section 8: a natural-born citizen who has lost Philippine citizenship may be a transferee of private lands, subject to limitations provided by law (the former-Filipino exception).
- 注 Easily got wrong: the Constitution does not say "foreigners may own up to 40% of a condominium." That is an interpretive practice under the Condominium Act (RA 4726), not a provision of the Constitution.
10-4. Section 10 — reservation of investment areas and "Filipino First"
- First paragraph: Congress may, upon recommendation of the economic and planning agency (NEDA), when the national interest dictates, reserve certain areas of investment to Filipino citizens or to corporations at least 60% Filipino-owned, and Congress may prescribe a higher percentage.
- Second paragraph: "In the grant of rights, privileges, and concessions covering the national economy and patrimony, the State shall give preference to qualified Filipinos." — the so-called "Filipino First" clause.
- Third paragraph: the State shall exercise the power to regulate and exercise authority over foreign investments.
- This Section 10 is the constitutional foundation of the Foreign Investment Negative List.
10-5. Section 11 — the 60/40 rule for public utilities
The gist of the original: - No franchise, certificate or other authorization for the operation of a public utility shall be granted except to Filipino citizens, or to corporations organized under Philippine law at least 60% of whose capital is owned by Filipino citizens. - No franchise shall be exclusive; the term shall not exceed 50 years. - Subject to amendment, alteration or repeal by Congress when the common good so requires. - Participation by foreign investors in the governing body shall be limited to their proportionate share in the capital, and all the executive and managing officers must be citizens of the Philippines.
In Gamboa v. Teves (G.R. No. 176579, 28 June 2011) the Supreme Court held that "capital" in Article XII, Section 11 refers to shares with voting rights in the election of directors, and not to total outstanding shares including non-voting preferred shares (the decision on LawPhil). In the PLDT case, only common shares form the numerator and denominator of the 60% computation.
10-6. Legislation that loosened the rules without amending the Constitution — RA 11659 (2022)
RA 11659 ("AN ACT AMENDING COMMONWEALTH ACT NO. 146, OTHERWISE KNOWN AS THE PUBLIC SERVICE ACT, AS AMENDED"), enacted on 21 March 2022, defined by statute, as an exhaustive list, the meaning of "public utility" in Article XII, Section 11 (the LawPhil text; Section 13(d) as amended by Section 4).
| What RA 11659 defines as a "public utility" (i.e. subject to 60/40) |
|---|
| ① Distribution of Electricity |
| ② Transmission of Electricity |
| ③ Petroleum and Petroleum Products Pipeline Transmission Systems |
| ④ Water Pipeline Distribution Systems and Wastewater Pipeline Systems |
| ⑤ Seaports |
| ⑥ Public Utility Vehicles |
As a result, telecommunications, aviation, railways, expressways, shipping and the like were reclassified as "public services" but not "public utilities," making 100% foreign ownership theoretically possible. 注 However, the constitutionality of RA 11659 was reported to have been challenged before the Supreme Court in October 2022 (Manila Standard, 2022-12-16), and as of August 2026 no report of a final Supreme Court determination could be confirmed (unconfirmed).
10-7. Other important provisions of Article XII
| Section | Content |
|---|---|
| 12 | Promotion of the preferential use of Filipino labor, domestic materials and locally produced goods |
| 14 | "The practice of all professions in the Philippines shall be limited to Filipino citizens, save in cases prescribed by law" — the basis on which foreigners cannot register as physicians, lawyers, accountants and so on |
| 17 | In times of national emergency, the State may temporarily take over or direct the operation of any privately owned public utility or business affected with public interest |
| 19 | The regulation or prohibition of monopolies, and the prohibition of combinations in restraint of trade and unfair competition (the constitutional basis of competition law) |
| 20 | An independent central monetary authority (i.e. the BSP). Its board members must be natural-born citizens, and the majority must come from the private sector |
| 21 | Foreign loans are subject to law and to regulation by the monetary authority. Information on foreign loans obtained by the government shall be made available to the public |
注 Article XVI, Section 11 is also part of the foreign ownership regime: the ownership and management of mass media is limited to citizens or to corporations or associations wholly owned and managed by Filipino citizens. The advertising industry must be at least 70% Filipino-owned, and all its executive and managing officers must be Filipino citizens.
11. Article XIII — Social Justice and Human Rights (the constitutional basis of agrarian reform)
- Section 1: Congress shall give highest priority to measures that "protect and enhance the right of all the people to human dignity, reduce social, economic, and political inequalities, and remove cultural inequities by equitably diffusing wealth and political power."
- Section 3 (Labor): the rights to self-organization, collective bargaining and to strike (in accordance with law), security of tenure, and an express living wage. "Local and overseas" = overseas workers are also constitutionally protected.
- Section 4 (Agrarian reform): "The State shall, by law, undertake an agrarian reform program founded on the right of farmers and regular farmworkers who are landless, to own directly or collectively the lands they till…" = a duty to carry out, by statute, agrarian reform founded on landless farmers' right to own the land they till. Subject to priorities set by Congress, reasonable retention limits, and the payment of just compensation.
- The implementing statutes are RA 6657 (the Comprehensive Agrarian Reform Law, CARP, 1988) and RA 9700 (CARPER, 2009).
- Even in 2026 the headlines read "35 years of CARP: are the farmers free?" (Rappler, 2026-08-22) and "Farmers: Agrarian reform remains unfinished" (Inquirer.net, 2026-06-16) — the constitutional promise is still being performed.
- Section 6: the principles of agrarian reform are applied to other natural resources, including the lease and concession of public lands. The rights of indigenous communities to their ancestral lands are reserved.
- Section 7: the preferential use of communal marine and fishing resources by subsistence fisherfolk, and protection of offshore fishing grounds from "foreign intrusion" — one of the domestic legal bases in the South China Sea (West Philippine Sea) question.
- Sections 17–19: the creation of the Commission on Human Rights (CHR). A chairman and four members, a majority of whom must be members of the Bar. Its powers include "investigating all forms of human rights violations involving civil and political rights." 注 The CHR has no prosecutorial power; only fiscal autonomy (automatic release of approved appropriations) is guaranteed to it by the Constitution.
12. Article XIV — Education, Science and Technology, Arts, Culture and Sports
- Section 2(2): a system of free public education at the elementary and high school levels, with elementary education compulsory.
- Section 3(1): all educational institutions are required to include the study of the Constitution (the reason every Philippine university has a constitution course).
- Section 4(2): ownership of educational institutions is limited to citizens or corporations at least 60% Filipino-owned (except those established by religious groups and mission boards). Control and administration must vest in Filipino citizens. No educational institution may be established exclusively for aliens, and aliens may not exceed one-third of enrollment.
- Section 4(3): the revenues and assets of non-stock, non-profit educational institutions used actually, directly and exclusively for educational purposes are exempt from taxes.
- Section 5(2): academic freedom shall be enjoyed in all institutions of higher learning.
The language provisions (Sections 6–9)
| Section | Content |
|---|---|
| 6 | "The national language of the Philippines is Filipino." It shall be further developed and enriched, and the Government shall take steps to use Filipino as a language of official communication and of instruction |
| 7 | "For purposes of communication and instruction, the official languages of the Philippines are Filipino and, until otherwise provided by law, English." The regional languages are the auxiliary official languages in the regions and auxiliary media of instruction. Spanish and Arabic shall be promoted on a voluntary and optional basis |
| 8 | The Constitution shall be promulgated in Filipino and English, and translated into the major regional languages, Arabic and Spanish |
| 9 | The establishment of a national language commission (the Komisyon sa Wikang Filipino) |
注 The misconception that "English is not an official language" is in circulation, but the original says "until otherwise provided by law, English" = English is also an official language until changed by statute. RA 12027 of 10 October 2024 ended mother-tongue instruction (MTB-MLE) from kindergarten to Grade 3 as a rule, and stated explicitly that the medium of instruction "shall revert to Filipino and, until otherwise provided by law, English (pursuant to Article XIV, Section 7 of the 1987 Constitution)" (the LawPhil text). A good example of Article XIV, Section 7 directly driving actual education policy.
13. Article XV — The Family (part of why divorce is difficult)
| Section | Content |
|---|---|
| 1 | The family is the foundation of the nation |
| 2 | "Marriage, as an inviolable social institution, is the foundation of the family and shall be protected by the State." |
| 3 | The right of spouses to found a family in accordance with their religious convictions and the demands of responsible parenthood; the protection of children; the right to a family living wage; the right of families to participate in policy-making |
| 4 | The duty of the family to care for its elderly members, and social security provided by the State |
注 Sorting out the misunderstandings about divorce
- The Constitution does not say "divorce is prohibited." That Article XV, Section 2 casts marriage as "an inviolable social institution," and Article II, Section 12 protects the family as "a basic autonomous social institution," creates a strong normative and political hurdle to divorce legislation.
- Under current law there are declarations of nullity, annulment and legal separation, and for Muslims, Presidential Decree 1083 (the Code of Muslim Personal Laws) allows divorce.
- An absolute divorce bill has passed the House but has stalled in the Senate. On 22 August 2026 the Commission on Human Rights was reported to have called for its enactment (Newswav, 2026-08-22). 注 As of 2026-08-26 there is no general divorce law in the Philippines (Rappler fact check, 2025-01-14).
14. Article XVII — the three ways of amending the Constitution
| # | Method | Requirement for proposal | Basis |
|---|---|---|---|
| ①Con-ass (Constituent Assembly — Congress proposing as a constituent body) | Congress | Three-fourths of all its Members | Art. XVII, Sec. 1(1) |
| ②Con-con (Constitutional Convention) | A constitutional convention | Congress may call a convention by a two-thirds vote of all its Members, or by a majority vote of all its Members submit to the electorate the question of calling such a convention | Art. XVII, Secs. 1(2) and 3 |
| ③People's Initiative | The people | A petition of at least 12% of the total number of registered voters, of which every legislative district must be represented by at least 3% of its registered voters. Not available within five years of ratification, and thereafter not more often than once every five years | Art. XVII, Sec. 2 |
- Methods ① and ② can effect either an "amendment" or a "revision," but a people's initiative can propose only "amendments" (the original limits it: "Amendments to this Constitution may likewise be directly proposed by the people").
- Section 4: any of these becomes valid when ratified by a majority of the votes cast in a plebiscite held not earlier than 60 nor later than 90 days after the approval of the proposal.
- 注 Whether "three-fourths of all Members" in a Con-ass is counted with both chambers voting jointly or each chamber separately is the greatest unresolved constitutional question, and charter-change debates founder on it every time. The text of the Constitution does not specify.
Related case law (all verified against the originals on LawPhil)
- Santiago v. COMELEC (G.R. No. 127325, 19 March 1997): RA 6735, taken as the implementing law for people's initiative, is inadequate for proposing constitutional amendments and lacks essential details such as signature verification procedures.
- Lambino v. COMELEC (G.R. No. 174153, 25 October 2006): a people's initiative may be used only for amendments, not for revisions. A shift from a presidential, bicameral system to a parliamentary, unicameral one affects more than a hundred provisions and is therefore a "revision."
- As of 26 August 2026 the 1987 Constitution has never been amended (i.e. zero amendments ratified in a plebiscite).
15. Articles XVI and XVIII — general and transitory provisions
- Article XVI, Section 11: mass media 100% Filipino, advertising 70% (as above).
- Article XVIII, Section 25: "After the expiration in 1991 of the Agreement between the Republic of the Philippines and the United States of America concerning military bases, foreign military bases, troops, or facilities shall not be allowed in the Philippines except under a treaty duly concurred in by the Senate and, when the Congress so requires, ratified by a majority of the votes cast by the people in a national referendum held for that purpose, and recognized as a treaty by the other contracting State."
- = Foreign military bases, troops or facilities are not allowed except under a treaty concurred in by the Senate, and the other State must also recognize it as a treaty.
- In Bayan v. Zamora (G.R. No. 138570, 10 October 2000) the Supreme Court upheld the Visiting Forces Agreement (VFA) as constitutional, the Senate having concurred by 18 votes (16 being required) and the United States acknowledging its binding force (the decision on LawPhil). This Section 25 is the starting point of every constitutional argument over EDCA, the VFA and the Mutual Defense Treaty.
- Article XVIII, Section 26: the authority to issue sequestration orders concerning ill-gotten wealth runs to 18 months after ratification (extendable by Congress).
- Article XVIII, Section 27: the effectivity provision only ("This Constitution shall take effect immediately upon its ratification…"). 注(Corrected in the 2026-08-26 verification. The earlier version treated the record of ConCom approval on 12 October 1986 and signing on 15 October as part of that section, but that record is the closing certification placed immediately after Section 27, not part of Section 27. Source: the text of the 1987 Constitution on LawPhil.)
- Article XVIII has 27 sections in all (Article III, the Bill of Rights, has 22). When you state a number of sections, recount it in the original.
16. Comparison with the earlier constitutions
| Constitution | Adoption / ratification | Form of government | President / Prime Minister | Foreign capital in natural resources and public utilities | Features |
|---|---|---|---|---|---|
| The 1935 Constitution | Ratified 14 May 1935 (per the text on LawPhil) | Presidential. Initially a unicameral National Assembly → bicameral by the 1940 amendment | Initially six years without re-election → four years, two terms, by the 1940 amendment | Natural resources vested in the State by Article XIII, Section 1. Public utilities 60% Filipino under Article XIV, Section 8 | Adopted under American rule (the Tydings-McDuffie Act). The 1947 "Parity Amendment" granted US citizens equal rights |
| The 1943 Constitution | The constitution of the Second Republic under Japanese occupation. The text gives no ratification date; Article XI provides for ratification "by a vote of the people or by a specially convened assembly" (the text on LawPhil) | A republic (in substance, under occupation) | The President was chosen by the National Assembly for a six-year term | — | The preamble refers to the "Greater East Asia War." It lapsed in 1945 |
| The 1973 Constitution | Declared ratified on 17 January 1973 by Proclamation No. 1102 through the "barangays" (citizens' assemblies). Yes 14,976,561 / No 743,869; separately, 14,298,814 opposed holding a further plebiscite | Parliamentary (initially). 17 Articles in all | "The executive power shall be exercised by the Prime Minister with the assistance of the Cabinet"; "legislative power shall be vested in the National Assembly" | 60% for both natural resources and public utilities | It took effect under martial law. Amended in 1976, 1980, 1981 and 1984, reverting in substance to a presidential system |
| The Freedom Constitution (1986) | Proclamation No. 3 of 25 March 1986 | A provisional revolutionary government | Provisional legislative power in the President | Selectively adopted the relevant provisions of the 1973 Constitution | It provisionally adopted only the 1973 Constitution's provisions on national territory, citizenship, the bill of rights and suffrage. Article V required a ConCom within 60 days and a plebiscite within 60 days of the draft's submission |
| The 1987 Constitution | Plebiscite of 2 February 1987 (Yes 16,622,111 / No 4,953,375); Proclamation No. 58 of 11 February | Presidential and bicameral | A six-year presidency with no re-election whatsoever | 60/40 (Art. XII, Secs. 2, 10 and 11) | "Grave abuse of discretion" review (Art. VIII, Sec. 1), congressional and judicial control of martial law, the independence of the constitutional commissions, the prohibition of political dynasties (awaiting an implementing law) |
注 Saying "the Philippine Constitution has been amended X times" tends to conflate separate constitutions (1935/1943/1973/1987) with amendments within a single constitution. The number of amendments to the 1987 Constitution itself is zero.
17. The charter-change debate as of 2026
| Date | Development | Source |
|---|---|---|
| 2024-02 to 03 | RBH 7 (Resolution of Both Houses No. 7, the House version) and RBH 6 (the Senate version) proposed "charter change limited to the economic provisions." They would insert the words "unless otherwise provided by law" into the foreign-equity provisions of Article XII (natural resources and public utilities), Article XIV (educational institutions) and Article XVI (advertising), leaving subsequent liberalization to ordinary legislation (the so-called "Bernas method") | Inquirer.net / PNA / GMA reports (2024-02-19 to 03-20) |
| 2024-03-20 | The House passed RBH 7 on final reading and transmitted it to the Senate | Inquirer.net / Manila Bulletin, 2024-03-20 |
| 2024-05 to 2025 | Deliberation stalled in the Senate. It lapsed with the end of the 19th Congress in June 2025 | Journal News Online, 2024-05-26 and others. 注 No primary source expressly recording the lapse could be reached |
| 2025-07-15 | A legislator said in the 20th Congress that "economic charter change is still possible" | Inquirer.net, 2025-07-15 |
| 2025-10-07 | The Office of the President: "what is needed now is not charter change but a change of heart" | Inquirer.net / PNA, 2025-10-07 |
| 2025-11-12 to 13 | The NUP (National Unity Party) proposed a constitutional convention in 2026 and clarification of the "forthwith" clause in impeachment. Former Chief Justice Puno: "since Congress is not trusted, a con-con is preferable" | Philstar.com, 2025-11-12 / Inquirer.net, 2025-11-13 |
| 2025-11-21 | Economists advocated abolishing the "Filipino-first" rule | Manila Bulletin, 2025-11-21 |
| 2026-01-29 to 31 | The Supreme Court finalized its ruling on the Vice-President's impeachment → Senate President Sotto said the Constitution "had been shaken" ("Nabulabog yung Konstitusyon") and expressed openness to charter change clarifying the impeachment provisions | ABS-CBN, 2026-01-30 / Inquirer.net, 2026-01-31 |

| 2026-02-13 | Senate President Sotto faced an indirect contempt petition over his criticism of the Supreme Court | PNA, 2026-02-13 |
| 2026-05 | Senator Imee Marcos claimed there was a charter-change plan "to do away with the 2028 elections" (no-el), which the Office of the President flatly denied as "fake news." She withdrew the video | Daily Tribune, 2026-05-21 / Philstar.com, 2026-05-25 and 30 / PNA, 2026-05-26 / Rappler fact check, 2026-06-03 |
The issues as they stand in 2026
- Economic charter change (economic Cha-cha): the leading approach is not to abolish 60/40 but to insert "unless otherwise provided by law" and leave it to Congress's discretion. 注 As of August 2026, however, no report of a concrete passage in the 20th Congress could be confirmed (unconfirmed).
- Amending the impeachment provisions: after the Supreme Court's January 2026 ruling, there is a push to clarify the meaning of the "one-year rule" and "forthwith" in the text of the Constitution. There are objections that this would encroach on judicial independence.
- Term extension and the "no-el" suspicion: every time charter change comes up, suspicions of "extending the terms of the President and legislators" or "cancelling the 2028 elections" erupt, and this has been the single biggest factor making charter change politically impossible. The Office of the President has repeatedly denied it.
- The procedural wall: the dispute over whether the Con-ass "three-fourths" is counted jointly or separately remains unresolved. For people's initiative, the inadequacy of the implementing law identified in Santiago has still not been cured.
18. Seven points Japanese practitioners must grasp
注(Corrected in the 2026-08-26 verification. The earlier heading said "nine points," but the items enumerated are seven.)
- Foreign individuals and foreign corporations cannot own land (Art. XII, Sec. 7). Inheritance and former Filipinos (Sec. 8) are the exceptions.
- All natural resources are owned by the State (Art. XII, Sec. 2). Development follows 60/40 as a rule, with room for 100% foreign capital only through an FTAA for large-scale minerals and petroleum.
- The 60/40 rule for "public utilities" is constitutional (Art. XII, Sec. 11). But RA 11659 (2022) narrowed "public utility" to an exhaustive list of six areas, taking telecommunications, aviation, railways and the like outside it. 注 The outcome of the constitutional challenge is unconfirmed.
- Under Gamboa, the 60% is computed on voting shares.
- Mass media is 100% and advertising 70% (Art. XVI, Sec. 11). The practice of professions is limited to Filipino citizens (Art. XII, Sec. 14). Educational institutions are also 60/40 (Art. XIV, Sec. 4(2)), with foreign enrollment capped at one-third.
- Public utility franchises run no more than 50 years and are non-exclusive; foreigners may sit on the board only in proportion to their shareholding, and all executive and managing officers must be Filipino citizens.
- All of these are constitutional and cannot be repealed by ordinary legislation. Liberalization comes down to two choices: rewriting the definitions (the RA 11659 approach) or amending the Constitution.

B. Places where indicators or definitions were supplied for clarity (rankings, superlatives, estimates)
| # | File | Content |
|---|---|---|
| B-1 | Japan–Philippines economic relationship | The indicator for cumulative ODA of "about ¥4.9 trillion" was made explicit: the sum of yen loans, grants and technical cooperation (yen loans alone are ¥4,330.273 bn). The basis is exchange of notes (technical cooperation on a budget-year expenditure basis). 注The cumulative note in the 2023 Data Book says yen loans are "on a loan-agreement basis," so the explanations differ by edition and both are presented |
| B-2 | Japan–Philippines economic relationship | The indicator for "the top DAC donor" = calendar year, gross disbursements, bilateral donors only. The latest published edition is the "Country Data Book 2024" = through 2022 actuals. It therefore cannot be written as "top as of 2026"; "consistently top through calendar 2022" is accurate. The 2022 row was newly added (Japan 1,468.13 / US 155.72 / Korea 125.18 / Australia 76.82 / Germany 34.29) |
| B-3 | Japan–Philippines economic relationship | MOFA's "Basic Data on the Philippines" gives a different ranking (by recipient of Japan's cumulative ODA, the Philippines is third after India and Bangladesh), added with its indicator so that it is not confused with being the top DAC donor |
| B-4 | Japan–Philippines economic relationship | The indicator for "Japan's eighth EPA partner" = order of entry into force (fourth by order of signature). The list of the eight in force is given |
| B-5 | Japan–Philippines economic relationship | The indicator for "19th in exports / 16th in imports" = rank by value in US dollars among countries and regions. The JETRO source file (xlsx) was re-read with openpyxl, and the −US$52.7 bn with China and +US$49.8 bn with the US were re-computed and confirmed |
| B-6 | Japan–Philippines economic relationship | A 注 was attached to the Philippine side's "second in imports from Japan," noting that it is effectively tied with third-place Korea, about US$30 million apart |
| B-7 | Japan–Philippines economic relationship | Made explicit that the EPA tariff-elimination ratios are the values at entry into force, on 2003 trade data (not the current applied tariffs) |
| B-8 | Japan–Philippines economic relationship | The indicator for steel's "more than 60% eliminated immediately" = by volume of Japanese exports |
| B-9 | The 1987 Constitution | The denominator was made explicit for the approval percentage in the 1987 plebiscite (77.04% on valid votes / 76.30% on total votes cast including abstentions). The 209,730 abstentions, the 21,785,216 total votes and the 83,288 precincts were added from the original |
| B-10 | Agrarian reform | Made explicit that "the 2026 DAR budget of ₱17.4 bn" is the amount proposed in the NEP, not the enacted GAA figure (the enacted figure is primary-source-unreached) |
| B-11 | Poverty and social security | Clarified the indicator for the number of 4Ps households: a ceiling of 4.4 million / a peak actual of more than 4.3 million / distinguishing the three stages of "request, NEP and GAA" |
| B-12 | Poverty and social security | Made explicit that the table of international agencies' cooperation with the Philippines is a table of grant-type actuals and does not include ADB and World Bank lending |
