1987 Philippine Constitution: Rights, Branches, and Accountability

The 1987 Philippine Constitution is the supreme law of the Philippines, ratified by national plebiscite on February 2, 1987, after the People Power Revolution ended two decades of authoritarian rule.¹ It creates three co-equal branches of government, guarantees a detailed set of individual rights, places hard limits on martial law, distributes economic control in favor of Filipino citizens, and lays out three separate routes for its own amendment. Every statute, executive order, and government action in the country must conform to its provisions or risk being struck down as unconstitutional.

The Three Branches of Government

Articles VI, VII, and VIII distribute authority across the legislative, executive, and judicial branches, each with defined powers and the ability to check the others.²

The President and the Executive Branch

Executive power belongs to the President, who is both Head of State and Commander-in-Chief of the Armed Forces. The President is elected by direct popular vote for a single six-year term and cannot run for reelection.² Day-to-day governance runs through cabinet departments. The President implements laws, negotiates treaties, and appoints officials across the executive branch and the judiciary.

Congress

Legislative power rests in a bicameral Congress. The Senate has 24 members elected at large nationwide.³ The House of Representatives includes district representatives elected from geographic constituencies and party-list nominees representing marginalized sectors such as labor, indigenous communities, women, youth, and overseas workers. Party-list representatives fill 20 percent of total House seats.⁴

Congress creates and repeals laws, approves the national budget, and confirms certain presidential appointments. When the President vetoes a bill, Congress can override that veto by a two-thirds vote of both chambers.⁵

The Supreme Court and the Judiciary

Judicial power is vested in the Supreme Court and lower courts established by law. The Supreme Court consists of one Chief Justice and 14 Associate Justices appointed by the President from a shortlist prepared by the Judicial and Bar Council.⁶ Congress plays no role in confirming these appointments, unlike in many other systems.

Article VIII grants the judiciary broad power of judicial review, including the authority to determine whether any branch of government has committed a grave abuse of discretion. The Supreme Court can strike down laws, executive orders, and other government actions that violate the Constitution.²

The Bill of Rights

Article III enshrines individual freedoms that the government cannot override absent extraordinary justification. These protections run against the state, meaning they limit what the government can do to people rather than regulating private conduct.

Due Process and Equal Protection

Section 1 guarantees that no person will be deprived of life, liberty, or property without due process of law, and that everyone receives equal protection under the law.² The government must follow fair procedures before taking action against anyone, and laws must apply uniformly rather than singling out particular groups for worse treatment.

Searches, Seizures, and Illegally Obtained Evidence

Section 2 protects people against unreasonable searches and seizures. For a search or seizure to be valid, a judge must personally determine that probable cause exists and issue a warrant specifically describing the place to be searched or the person or things to be seized.² Section 3(2) then declares that any evidence obtained in violation of these protections is inadmissible for any purpose in any proceeding.⁷ Even evidence that clearly proves guilt cannot be used if it was seized illegally. Placing this exclusionary rule directly in the Constitution makes it far harder to weaken than an ordinary statute.

Religious Freedom, Expression, and Access to Information

Section 5 prohibits the government from establishing a state religion or restricting the free exercise of religious worship. No religious test can be required for the exercise of civil or political rights.⁷

Section 4 bars the government from passing laws that restrict freedom of speech, expression, or the press. Section 7 recognizes the public’s right to access official records, documents, and government research data used as a basis for policy decisions.² Citizens can criticize government action and obtain the information needed to do so meaningfully.

Rights of the Accused

Section 12 guarantees that anyone under investigation for a crime has the right to remain silent and to have independent legal counsel. These rights cannot be waived except in writing and in the presence of a lawyer, a safeguard specifically aimed at preventing coerced confessions.²

Section 14 adds protections at trial. Every accused person is presumed innocent until proven otherwise and has the right to be heard by counsel, to be informed of the charges, to a speedy and public trial, to confront witnesses, and to compel the attendance of witnesses and production of evidence.⁷ Section 19 prohibits excessive fines and cruel, degrading, or inhuman punishment.²

The Right to Unionize

Article III, Section 8 protects the right of people in both the public and private sectors to form unions, associations, or societies for lawful purposes.⁸ Placing this right in the Bill of Rights gives it the same constitutional weight as freedom of speech or due process. Article XIII adds specific labor guarantees: workers are entitled to organize, engage in collective bargaining, conduct peaceful concerted activities including strikes, and enjoy security of tenure, humane working conditions, and a living wage.⁹

Writs of Amparo and Habeas Data

Beyond the rights listed in Article III, the Philippine legal system provides two specialized writs for urgent situations where ordinary court processes move too slowly to prevent harm. The Supreme Court created both under its rule-making authority, drawing on the constitutional rights to life, liberty, security, and privacy.

The Writ of Amparo, introduced in 2007, is available to any person whose right to life, liberty, or security is violated or threatened, and was developed specifically to address extrajudicial killings and enforced disappearances.¹⁰ Courts hearing amparo petitions can issue temporary protection orders, authorize inspections, and order the production of documents. Government officials named as respondents face a heightened standard: they must prove they exercised extraordinary diligence and cannot simply invoke the presumption that official duties were regularly performed.

The Writ of Habeas Data protects informational privacy. Any person whose privacy is violated or threatened by the unlawful gathering, collecting, or storing of personal data can petition the court to correct, suppress, or destroy the offending records.¹¹

Limits on Martial Law and Emergency Powers

The 1987 Constitution’s treatment of martial law reflects hard lessons from the Marcos era. Article VII, Section 18 allows the President to declare martial law or suspend the privilege of the writ of habeas corpus, but surrounds that power with restrictions that did not exist under the previous constitution.¹²

Martial law can only be declared in cases of actual invasion or rebellion when public safety requires it, and it automatically expires after 60 days. The President must report to Congress within 48 hours of the declaration. Congress can revoke it at any time by a majority vote of all its members voting jointly, and that revocation cannot be overridden by the President. If Congress is not in session, it must convene within 24 hours without waiting for a presidential call.¹²

Any citizen can challenge the factual basis of a martial law declaration before the Supreme Court, which must rule within 30 days.¹³ The Court reviews whether the President had probable cause to believe an actual invasion or rebellion existed and that public safety required the declaration.

The Constitution also draws bright lines around what martial law cannot do. It does not suspend the Constitution, replace the functioning of civil courts or Congress, or authorize military tribunals to try civilians where civil courts still operate. Any person arrested during a suspension of the writ of habeas corpus must be judicially charged within three days or released.¹²

Accountability for Public Officials

Article XI declares that public office is a public trust, and it creates several overlapping mechanisms to enforce that principle.

Impeachment

Only five categories of officials can be removed through impeachment: the President, the Vice-President, members of the Supreme Court, members of the Constitutional Commissions, and the Ombudsman. The grounds are culpable violation of the Constitution, treason, bribery, graft and corruption, other high crimes, and betrayal of public trust.² All other public officers can be removed through ordinary legal proceedings but not through impeachment.

The Ombudsman and Sandiganbayan

The Office of the Ombudsman is an independent watchdog with power to investigate and prosecute any public official or employee whose actions appear illegal, unjust, or inefficient. It holds primary jurisdiction over cases heard by the Sandiganbayan, the country’s special anti-graft court.¹⁴ The Ombudsman can issue subpoenas, compel testimony, access bank records, inspect government premises, and preventively suspend officials under investigation for up to six months without pay when the evidence of guilt is strong.

The Sandiganbayan itself has exclusive jurisdiction over graft and corruption cases involving officials at the level of regional director or higher (Salary Grade 27 and above). Its reach extends to provincial governors, city mayors, military colonels and above, members of Congress, and heads of government-owned corporations, among others.¹⁵

Independent Commissions

Article IX establishes three commissions that operate outside the control of the other branches.² The Civil Service Commission oversees merit-based hiring and career progression across the government bureaucracy and adjudicates administrative cases involving government workers. The Commission on Elections (COMELEC) manages all elections and enforces election laws, with authority to adjudicate disputes over candidate qualifications and results. The Commission on Audit examines all government accounts involving public revenue and expenditures, defining auditing rules and inspecting government projects to prevent waste. The approved budgets of these commissions are automatically released, preventing the legislature from using budget cuts as leverage over their work.

Under Article XIII, the Commission on Human Rights operates as a separate independent office. It is composed of a chairperson and four members, a majority of whom must be members of the Bar.⁹ The CHR investigates civil and political rights violations, exercises visitorial powers over jails and detention facilities, grants immunity to witnesses, and monitors the government’s compliance with international human rights treaties. Its annual appropriations are also automatically released.

Economic Nationalism and Land Ownership

Article XII regulates the national economy to ensure that Philippine resources primarily benefit Filipino citizens. All lands of the public domain, minerals, petroleum, forests, fisheries, wildlife, and other natural resources are owned by the state. Except for agricultural lands, natural resources cannot be sold or permanently transferred into private hands. The state may enter into co-production, joint venture, or production-sharing agreements with Filipino citizens or with corporations at least 60 percent owned by Filipino citizens, for periods of up to 25 years, renewable once for another 25 years.¹⁶

No franchise for operating a public utility can be granted except to Filipino citizens or to corporations organized under Philippine law with at least 60 percent Filipino ownership. These franchises cannot be exclusive in character or last longer than 50 years. Foreign investors are limited to proportionate representation on the governing body of any public utility, and all executive and managing officers must be Filipino citizens.¹⁷

Private land can only be transferred to individuals or entities qualified to acquire public domain lands, which effectively means Filipino citizens and corporations meeting the 60 percent ownership threshold. The Constitution itself carves out one exception: hereditary succession, where a foreign heir can inherit land from a Filipino relative. Former Filipino citizens who lost their citizenship may also acquire private land, subject to limits set by Congress.¹⁶ Those who reacquire citizenship under the Citizenship Retention and Re-acquisition Act regain full property rights as Filipino citizens.¹⁸ Other foreigners cannot own land, though separate legislation permits ownership of condominium units and long-term leases.

Local Governments and Autonomous Regions

Article X divides the country into provinces, cities, municipalities, and barangays, and guarantees each local government unit local autonomy.¹⁹ Each unit can create its own revenue sources and levy taxes, fees, and charges, with the proceeds belonging exclusively to that unit. Local governments are entitled to an automatic, legally determined share of national taxes and an equitable share in the proceeds from developing natural resources within their territory.

The Constitution also mandates the creation of autonomous regions in Muslim Mindanao and the Cordilleras, recognizing their distinct historical and cultural heritage. Congress must enact an organic act for each region, which only takes effect when constituent provinces and cities approve it by majority vote in a plebiscite.¹⁹ Each autonomous region has its own executive department and elected legislative assembly, along with special courts handling personal, family, and property law.

How the Constitution Can Be Changed

Article XVII provides three routes for changing the Constitution, distinguishing between amendments (targeted changes to specific provisions) and revisions (fundamental overhauls of the entire document).²⁰

Congress itself can propose amendments or revisions by a vote of three-fourths of all its members acting as a Constituent Assembly.² This is the most direct route because it uses the existing legislature.

Congress may also call a Constitutional Convention by a two-thirds vote of all its members, or it may submit the question of whether to call a convention to the voters by a majority vote of all its members.² Delegates are elected specifically for the task of drafting constitutional changes. Like a Constituent Assembly, a convention can propose either amendments or a full revision.

Citizens can also propose amendments directly through a people’s initiative, a petition signed by at least 12 percent of all registered voters, with at least 3 percent of the registered voters in every legislative district represented.²⁰ A people’s initiative can only propose amendments, not a full revision, and cannot be exercised within five years of the Constitution’s ratification or more often than once every five years.

No matter which method produces a proposed change, it does not take effect until ratified by a majority of votes cast in a national plebiscite held no earlier than 60 days and no later than 90 days after the proposal is approved.²⁰ The final decision on changes to the fundamental law rests with the voters.
