A Philippine Legal Article

I. Introduction

Few issues in Philippine economic law generate more confusion than the relationship between the constitutional 60–40 foreign ownership rule and the more recent liberalization of the Public Service Act. The confusion is understandable. For decades, many Filipinos, lawyers, businesses, and regulators loosely treated “public utilities,” “public services,” and heavily regulated industries as if they were the same thing. They are not.

The modern legal position is this: the 60–40 rule remains alive and binding, but it applies only where the Constitution or statutes actually impose it. The amended Public Service Act narrowed the scope of businesses considered “public utilities,” which means many sectors once assumed to be constitutionally restricted are no longer subject to the 60–40 ownership cap under that theory. That change did not abolish the Constitution’s economic nationalism provisions. It redefined where those provisions operate.

To understand this properly, one must separate constitutional text, statutory definitions, regulatory practice, and jurisprudence.

II. The Constitutional Foundation of the 60–40 Rule

The phrase “60–40 rule” generally refers to the constitutional requirement that certain activities or enterprises be at least 60% owned by Filipino citizens, with foreign equity limited to 40%.

The principal constitutional anchor is Article XII of the 1987 Constitution, especially:

Section 2, on exploration, development, and utilization of natural resources;
Section 11, on the operation of a public utility;
other provisions dealing with land, mass media, educational institutions, advertising, and reserved areas of investment.

For purposes of the present topic, the most important is Article XII, Section 11, which provides in substance that no franchise, certificate, or authorization for the operation of a public utility shall be granted except to citizens of the Philippines or to corporations organized under Philippine law with at least 60% of whose capital is owned by such citizens. It also contains related conditions, including limitations on the participation of foreign investors in governing bodies and the requirement that executive and managing officers be citizens of the Philippines.

This is why, historically, a business classified as a public utility was understood to be constitutionally subject to Filipino control.

Two points are critical:

The Constitution does not impose a blanket 60–40 rule on every regulated industry. It applies only to activities covered by the constitutional text or valid legislation.
The constitutional term is “public utility,” not “public service.” That distinction became decisive after the Public Service Act amendments.

III. The Pre-Liberalization Landscape: Why Confusion Persisted for So Long

Before the recent reforms, the Philippines operated under Commonwealth Act No. 146, the Public Service Act (PSA), a law dating from 1936. Over time, the PSA became the basic framework for the regulation of enterprises “affected with public interest,” many of which required a certificate of public convenience or similar authority from regulators such as the Public Service Commission historically, and later specialized agencies.

The problem was that the PSA’s operative category was “public service,” a broader statutory term, while the Constitution used the narrower term “public utility.” In practice, however, many sectors regulated as public services were also treated as though they were public utilities for foreign ownership purposes.

That regulatory and commercial habit led to a very expansive understanding of what the Constitution supposedly restricted. Sectors such as telecommunications, transportation, shipping, railways, airlines, and others were often placed under the same ownership assumptions because they were franchise-based, regulated, or served the public.

For decades, the line between:

a regulated business,
a public service, and
a constitutionally restricted public utility

was not always sharply maintained.

That older approach was disrupted by legislative reform.

IV. The Public Service Act Liberalization: What Changed

The major turning point came with Republic Act No. 11659 (2022), which amended the Public Service Act.

Its central innovation was to expressly distinguish “public utility” from the broader category of “public service.” Under the amended law, only certain enumerated services are classified as “public utilities.” Everything else may still be a public service or a regulated activity, but it is not automatically a public utility for constitutional ownership purposes.

A. The core effect of RA 11659

RA 11659 effectively narrowed the field of enterprises subject to the constitutional 60–40 ownership rule under Article XII, Section 11 by limiting the statutory definition of public utility to specific sectors.

In substance, the amended law identifies the following as public utilities:

distribution of electricity
transmission of electricity
petroleum and petroleum products pipeline transmission systems
water pipeline distribution systems and wastewater pipeline systems, including sewerage pipeline systems
seaports
public utility vehicles

These are the sectors that continue to be most clearly within the constitutional regime for public utility ownership restrictions.

By contrast, many sectors long treated as restricted—most notably telecommunications—were no longer classified as public utilities under the amended PSA, although they remain regulated and may be subject to separate national security and reciprocity rules.

B. The policy objective

The purpose of the reform was to attract foreign investment into sectors viewed as essential to growth, especially infrastructure and digital connectivity, while preserving Filipino control over a narrower class of businesses deemed fundamental to public welfare and sovereignty.

The amendment was therefore not a repeal of constitutional nationalism. It was a recalibration of the legal map.

V. Public Utility vs. Public Service: The Most Important Distinction

This is the heart of the issue.

Public utility

A public utility is constitutionally significant because Article XII, Section 11 directly imposes nationality restrictions on it. After RA 11659, the term is treated as a narrower category.

If an enterprise is a public utility, then the 60–40 rule generally applies, along with related constitutional requirements.

Public service

A public service is a broader statutory concept. A business may be a public service because it is subject to regulation, franchise requirements, or public-interest obligations. But that does not necessarily mean it is a public utility under the Constitution.

After liberalization, many businesses remain regulated public services without being constitutionally capped at 40% foreign ownership by reason of being public utilities.

Why this matters

This distinction determines whether:

foreign equity is capped at 40%;
foreigners can own a controlling stake;
franchise holders must satisfy constitutional nationality rules;
governing boards and executive positions must satisfy citizenship rules specific to public utilities.

A business may still need licenses, permits, or legislative franchises and yet no longer be bound by the constitutional 60–40 cap if it is not legally classified as a public utility.

VI. What the 60–40 Rule Still Covers

Even after PSA liberalization, the 60–40 rule remains highly important in Philippine law.

A. Public utilities under Article XII, Section 11

Where an enterprise falls within the amended statutory definition of public utility, the constitutional restriction remains in force.

That means the operator must generally be:

a Philippine citizen; or
a Philippine corporation with at least 60% Filipino-owned capital.

There are also governance restrictions. The Constitution provides that:

participation of foreign investors in the governing body of a public utility enterprise must be proportional to their share in the capital; and
all executive and managing officers must be Philippine citizens.

B. Natural resources

Separate from public utilities, the Constitution imposes nationality restrictions on the exploration, development, and utilization of natural resources. This is not really a PSA issue; it is a different constitutional field. But it is part of the broader 60–40 landscape.

The State has full control and supervision over natural resources. Agreements involving private participation are constitutionally structured and heavily regulated. Foreign participation is permitted only within constitutional and statutory limits.

C. Land ownership

Foreign nationals cannot own land in the Philippines, except in limited constitutionally permitted situations such as hereditary succession. Philippine corporations owning land generally must meet nationality requirements. This is distinct from the PSA, but often confused with it.

D. Other nationality-restricted sectors

Philippine law also restricts or regulates foreign participation in:

mass media
advertising
educational institutions
certain areas under the Foreign Investments Act and Foreign Investment Negative List
retail trade, subject to the Retail Trade Liberalization Act as amended
practice of professions, usually subject to citizenship and reciprocity rules
financing, lending, and other sectors subject to specialized statutes

These restrictions do not disappear merely because the PSA was liberalized.

VII. Sectors Most Affected by PSA Liberalization

A. Telecommunications

Telecommunications is perhaps the clearest example of the reform’s impact. Historically, telecoms were widely treated as constitutionally restricted public utilities. Under the amended PSA, telecommunications is no longer automatically classified as a public utility.

The practical effect is that foreign ownership can exceed 40%, subject to other laws, rules, and national security safeguards.

However, this does not mean telecoms became unregulated. It remains a heavily regulated industry subject to:

congressional franchise requirements where applicable,
National Telecommunications Commission regulation,
competition law,
cybersecurity and data-related regulation,
national security review mechanisms under RA 11659 and related rules.

B. Airlines and airports

Air transportation has long been treated as sensitive, but PSA liberalization changed the framework by which nationality restrictions are analyzed. Ownership questions in aviation may still be affected by specialized laws, constitutional interpretation, treaty commitments, and sectoral regulation. The answer is not as simple as “fully open” or “still 60–40.” One must examine the specific activity, the operator, and the applicable aviation laws and franchise requirements.

C. Railways, subways, expressways, and transport infrastructure

These sectors were historically associated with public utility logic. After the PSA amendments, the analysis is now more sector-specific. Some transport activities remain within the public utility sphere, especially those explicitly covered, while infrastructure development or operation may involve separate concession and procurement regimes rather than simple constitutional ownership analysis.

D. Shipping and ports

Seaports remain expressly classified as public utilities under the amended PSA, so the constitutional restriction still matters there. But “shipping” and related logistics activities require careful parsing, because not all maritime activities are identical in legal classification.

E. Digital and other emerging infrastructure

The amended framework was designed partly to make room for greater foreign investment in modern infrastructure and services not intended to remain within the traditional public utility core.

VIII. The Role of National Security Exceptions and Safeguards

One common misunderstanding is that PSA liberalization simply allows unrestricted foreign control in all newly opened sectors. That is incorrect.

RA 11659 built in national security protections, especially for investments in sectors considered critical infrastructure.

A. Critical infrastructure

The amended law defines and regulates critical infrastructure, generally referring to public services so vital that their incapacity or destruction would have a debilitating impact on national security, public safety, economy, or public health.

A public service can be not a public utility and yet still be critical infrastructure.

That is a major conceptual shift.

B. Foreign state-owned enterprises

The amended law subjects investments by foreign state-owned enterprises in critical infrastructure to tighter scrutiny or restriction. This reflects concern that strategic assets could be influenced by foreign governments rather than ordinary private investors.

C. Reciprocity

Foreign nationals or entities from countries that do not accord reciprocity to Filipinos may face limitations in investing in certain public services involving critical infrastructure.

D. Executive review

The law empowers the government, through appropriate agencies and review mechanisms, to examine investments for national security implications. Thus, even where the 60–40 cap no longer applies, foreign investment is not automatically free from public-law control.

IX. How to Analyze a Sector Today: The Correct Legal Method

When a lawyer, regulator, or investor confronts a foreign ownership issue, the proper sequence is no longer “Is this a public service?” It is more precise.

Step 1: Identify the exact activity

Do not analyze the industry label alone. Ask what the enterprise actually does. Is it electricity distribution, telecom operation, water distribution, port operation, transport service, data infrastructure, concession management, or something else?

Step 2: Check the Constitution

Is the activity one of those directly covered by constitutional nationality restrictions, such as:

public utility,
natural resources,
land,
mass media,
educational institutions,
advertising?

Step 3: Check the amended Public Service Act

If the issue is whether the business is a public utility, determine whether it falls within the sectors expressly enumerated by the amended PSA.

Step 4: Check sector-specific statutes and regulations

Even if the enterprise is not a public utility, there may be restrictions under:

franchise laws,
regulatory codes,
special charters,
nationality rules under other statutes,
foreign investment negative list entries,
national security review mechanisms.

Step 5: Examine corporate structure and beneficial ownership

Even where 60–40 formally applies, compliance is not merely nominal. One must analyze voting rights, beneficial ownership, board composition, control rights, and any arrangements that may undermine Filipino control.

X. The “Capital” Question and the Control Test

No serious discussion of the 60–40 rule is complete without addressing how Filipino ownership is measured.

A. “Capital” in constitutional law

The Supreme Court’s jurisprudence, especially Gamboa v. Finance Secretary and subsequent clarifications, significantly affected how the 60–40 rule is computed in constitutionally restricted enterprises.

The essential point associated with the Gamboa doctrine is that in corporations operating public utilities, the constitutional requirement of at least 60% Filipino ownership must not be satisfied by superficial arithmetic alone. The rule must ensure real Filipino control, especially over voting shares.

The case is often discussed for the proposition that:

compliance must be examined with attention to the class of shares carrying voting rights; and
Filipino ownership must not be diluted through structures that leave control effectively in foreign hands.

Later jurisprudence and implementing rules refined the application, but the anti-circumvention principle remains central.

B. Full beneficial ownership and control

Philippine regulators and courts generally look beyond paper compliance. Arrangements such as:

nominee structures,
side agreements,
preferred economic rights with disproportionate control effects,
shareholder covenants that effectively transfer control,
debt-to-control devices,

may draw scrutiny if they defeat the constitutional objective.

C. Why this still matters after liberalization

Because PSA liberalization narrowed but did not abolish the category of public utility, the Gamboa framework remains important in sectors that still fall within constitutional restriction.

XI. Does PSA Liberalization Override the Constitution?

No.

This is the most fundamental legal point.

A statute cannot amend the Constitution. The amended Public Service Act did not repeal Article XII, Section 11. What it did was define, for statutory and regulatory purposes, the scope of public utility more narrowly than before.

So the legal logic is:

the Constitution restricts public utilities;
Congress, through the PSA as amended, identified which public services are to be treated as public utilities under the current statutory framework;
therefore, only those falling within that narrower category remain subject to the constitutional 60–40 rule by reason of being public utilities.

The statute operates within the Constitution, not above it.

That said, because constitutional meaning is ultimately for the courts to interpret, the final word on contested classifications always remains judicial.

XII. Can Congress Narrow the Meaning of “Public Utility”?

This is one of the most debated legal questions.

The argument in favor

Supporters of the amendment argue that the Constitution did not itself define “public utility” exhaustively. Therefore, Congress may validly determine, by legislation, which activities count as public utilities for purposes of regulation and nationality restrictions, so long as it does not contradict the Constitution.

This view treats “public utility” as a term with room for legislative specification.

The critical argument

Critics argue that Congress cannot, by simple statute, reduce the constitutional scope of activities that should properly be considered public utilities if those activities inherently belong to that constitutional category.

In other words, if a business is constitutionally a public utility in substance, Congress should not be able to escape the 60–40 rule by relabeling it.

The practical position

As a matter of operative law, RA 11659 is in force, and the legal framework now distinguishes public utilities from other public services according to its text. Unless and until the Supreme Court rules otherwise in a particular controversy, regulators and investors generally work within that framework.

XIII. Public Utility Franchises After Liberalization

A related area of confusion concerns franchises.

Many industries require a legislative franchise, certificate, permit, or regulatory authorization. But a franchise requirement does not automatically trigger the constitutional 60–40 rule.

The correct question is not simply, “Does the business need a franchise?” The correct question is:

Is the franchise for the operation of a constitutionally restricted public utility?

If yes, Article XII, Section 11 applies.

If no, then other laws may govern, but the public utility nationality rule may not.

This distinction is especially important in telecommunications and other formerly assumed restricted sectors.

XIV. Relationship with the Foreign Investments Act and the Negative List

The Foreign Investments Act (FIA) and the Foreign Investment Negative List (FINL) remain essential to understanding foreign ownership in the Philippines.

A. The FINL is separate from the PSA

A sector may be open under the PSA and still restricted under the Constitution or another statute reflected in the FINL.

B. The FINL is not the source of constitutional restrictions

The FINL operationalizes restrictions for investment purposes, but constitutional limitations exist independently.

C. Sector-specific analysis remains necessary

An investor cannot rely on a general statement that the PSA is liberalized. One must still examine:

whether the activity is on the FINL,
whether other sectoral statutes impose limits,
whether licensing agencies apply nationality standards,
whether national security screening is triggered.

XV. Corporate Governance Consequences in Public Utilities

Where a business remains a public utility, ownership is only one part of the constitutional regime.

A. Board participation

Foreign investors may participate in the governing body only in proportion to their capital share.

B. Executive and managing officers

These must be Philippine citizens in public utility corporations.

C. Control rights in shareholder agreements

Even if equity percentages appear compliant, governance agreements that effectively place control in foreign hands may be vulnerable.

D. Regulatory disclosures

Public utility applicants and operators may be required to disclose nationality, ownership chains, beneficial ownership, and governance arrangements more rigorously than ordinary corporations.

XVI. The Anti-Dummy Law and Circumvention Risks

The Anti-Dummy Law remains relevant in constitutionally or statutorily restricted sectors.

Its purpose is to prevent schemes by which foreign nationals circumvent nationality requirements through dummies, nominees, or backdoor control mechanisms.

Potential risk areas include:

sham Filipino shareholders,
voting arrangements that nullify Filipino control,
management agreements giving effective foreign operation of a restricted enterprise,
debt or security arrangements functioning as disguised control transfers.

Even after PSA liberalization, the Anti-Dummy framework continues to matter wherever nationality restrictions survive.

XVII. Common Misconceptions

Misconception 1: “The 60–40 rule is gone.”

False. It still applies to public utilities and other constitutionally or statutorily restricted sectors.

Misconception 2: “All public services are still subject to 60–40.”

False. After RA 11659, many public services are no longer public utilities.

Misconception 3: “Telecommunications is still automatically 60–40 because it is important.”

Importance alone is not the test. Under the amended PSA, telecoms is no longer automatically within the narrowed list of public utilities, though it remains regulated and may be treated as critical infrastructure.

Misconception 4: “If a business is regulated, it must be a public utility.”

False. Regulation and public utility status are not the same.

Misconception 5: “A franchise requirement means foreigners cannot control the company.”

Not necessarily. The key is whether the franchise concerns a constitutionally restricted public utility or another restricted activity.

Misconception 6: “As long as 60% of total shares are Filipino-owned, the Constitution is satisfied.”

Not always. One must consider the Gamboa line of cases, voting rights, and actual control.

XVIII. Practical Implications for Investors, Regulators, and Lawyers

For investors

The amended PSA creates opportunities for foreign majority ownership in sectors once treated as closed or capped. But diligence must go beyond headlines. Investors must examine classification, licensing, national security review, reciprocity, sectoral law, and corporate governance.

For regulators

Regulators must avoid using obsolete assumptions. The question is no longer whether a business is “public-facing” or “regulated,” but whether it falls within the legally defined public utility category or some other restriction.

For Philippine corporations

Corporate structuring now requires sharper legal engineering. Some industries can now accommodate higher foreign equity, but only if the enterprise is properly classified and structured.

For litigators and constitutional lawyers

The amended PSA may continue to generate challenges on the extent of Congress’s authority to define public utility. The line between legislative classification and constitutional substance remains fertile ground for litigation.

XIX. The Broader Constitutional Policy Tension

This subject sits at the intersection of two recurring constitutional values:

economic nationalism and Filipino control of strategic sectors, and
economic liberalization and openness to foreign capital.

The 1987 Constitution strongly reflects national patrimony concerns. At the same time, modern development policy often argues that excessive ownership restrictions deter investment, weaken competition, and slow infrastructure growth.

RA 11659 is a legislative attempt to balance those values by:

retaining Filipino control over a smaller set of core public utilities,
opening many other public services to greater foreign participation,
preserving national security review over strategic assets.

Whether that balance is optimal is a matter of policy debate. But as a legal matter, that is the architecture now in place.

XX. Illustrative Comparison Table in Narrative Form

To avoid reducing the issue to oversimplified charts, it is useful to state the contrast directly.

Under the traditional understanding, a broad range of businesses serving the public were often treated as if they were constitutionally restricted public utilities. Ownership analysis was correspondingly conservative, and many sectors assumed they had to remain 60% Filipino-owned.

Under the post-RA 11659 framework, only those sectors expressly treated as public utilities remain clearly within Article XII, Section 11 by reason of that status. Other public services may now admit greater foreign ownership, unless some separate constitutional or statutory restriction applies.

Thus:

public utility = still generally subject to 60–40;
public service but not public utility = may be open beyond 40%, subject to other laws;
critical infrastructure = may still face national security restrictions even if not a public utility.

That three-part distinction is the modern key.

XXI. Where Future Legal Controversy Is Most Likely

Several issues may continue to evolve in doctrine and practice:

1. Constitutional challenges to statutory narrowing

Courts may be asked whether Congress validly narrowed the category of public utilities.

2. Critical infrastructure review

How aggressively the government reviews foreign investment in strategic sectors may shape the practical reach of liberalization.

3. Beneficial ownership and control

As foreign investors seek creative structures, regulators may intensify scrutiny of who really controls strategic enterprises.

4. Interaction with sector-specific laws

Different industries may produce different answers depending on franchise laws, agency rules, and treaty commitments.

5. Digital infrastructure and convergence

As telecom, data, cloud, energy, transport, and platform services converge, legal classification may become harder.

XXII. Bottom-Line Legal Conclusions

The clearest way to state the law is this:

The Philippine Constitution still restricts foreign ownership in public utilities to 40%, requiring at least 60% Filipino ownership.
The amended Public Service Act did not remove that constitutional rule. It narrowed the class of enterprises considered public utilities.
Not all public services are public utilities. This is now the controlling statutory framework.
Many sectors once assumed to be constitutionally restricted are no longer automatically covered by the 60–40 rule under the public utility clause.
Foreign ownership may now exceed 40% in many public services, but not without limits. Other statutes, constitutional provisions, regulatory requirements, reciprocity rules, and national security safeguards may still apply.
Where the 60–40 rule still applies, compliance must reflect real Filipino control, not merely formal share-counting.
Every foreign ownership issue in the Philippines must be analyzed sector by sector, statute by statute, and structure by structure.

XXIII. Final Synthesis

The phrase “60–40 rule vs. Public Service Act liberalization” suggests a conflict, but legally the relationship is more precise than adversarial.

There is no true contradiction.

The 60–40 rule is a constitutional command that continues to govern areas the Constitution protects, especially public utilities. The Public Service Act liberalization is a statutory reform that narrows which enterprises are classified as public utilities and therefore narrows the set of businesses to which that constitutional rule applies under that category.

So the real legal development is not that the Constitution gave way. It is that the statutory gateway into the constitutional restriction became narrower.

That is why the modern Philippine foreign investment analysis can no longer rely on slogans. It requires disciplined classification:

Is the activity a public utility?
Is it merely a public service?
Is it critical infrastructure?
Is it separately restricted by the Constitution or another statute?
Who actually owns and controls the corporation?

Only after those questions are answered can one determine whether the 60–40 rule still governs, or whether PSA liberalization allows a more open ownership structure.

In Philippine law today, that is the difference between getting the issue generally right and getting it legally right.
