ARTICLE I: NATIONAL TERRITORY

Comprehensive Study Guide with QuAMTO Questions and Expanded Analysis

CONSTITUTIONAL TEXT

Section 1. The national territory comprises the Philippine archipelago, with all the islands and waters embraced therein, and all other territories over which the Philippines has sovereignty or jurisdiction, consisting of its terrestrial, fluvial, and aerial domains, including its territorial sea, the seabed, the subsoil, the insular shelves, and other submarine areas. The waters around, between, and connecting the islands of the archipelago, regardless of their breadth and dimensions, form part of the internal waters of the Philippines.

I. SCOPE OF NATIONAL TERRITORY (TERRESTRIAL, AERIAL, AND FLUVIAL DOMAINS)

QuAMTO Question 1: Jurisdiction over Foreign Embassies (2009 BAR)

FACTS: William, a private American citizen, was inside the U.S. embassy when he got into a heated argument with a private Filipino citizen. He killed the person in front of many witnesses. The police arrested him and brought him to the police station. During the investigation, William protested his arrest, arguing that since the incident took place inside the U.S. embassy, Philippine courts have no jurisdiction because the U.S. embassy grounds are not part of Philippine territory; thus, technically, no crime under Philippine law was committed.

QUESTION: Is William correct?

ANSWER: No. William is not correct.

EXPANDED ANALYSIS:

Why This Answer?

1. Territorial Sovereignty Over Embassy Grounds

The premises occupied by the United States Embassy do not constitute territory of the United States but of the Philippines. This is a fundamental principle of international law that is often misunderstood by the general public.

Key Principle: Diplomatic premises enjoy immunity from local jurisdiction, but this immunity does not transform the embassy grounds into foreign territory. The distinction is critical:

2. Crimes and Jurisdiction

Crimes committed within embassy premises are subject to the territorial jurisdiction of the Philippines. The determining factor is whether the alleged offender enjoys diplomatic immunity, not whether the location is considered "Philippine territory."

3. William's Status

Since William has no diplomatic immunity (he is described as a "private American citizen"), the Philippines can prosecute him if it acquires custody over him. The mere fact that he was physically present in the embassy does not shield him from Philippine criminal jurisdiction.

Leading Case: Reagan v. Commissioner of Internal Revenue, G.R. No. L-26379, 27 December 1969

Bernas Commentary: Bernas explains that the common misconception about embassy grounds stems from the extensive immunities that embassies enjoy under the Vienna Convention on Diplomatic Relations. However, these immunities relate to inviolability and exemption from local jurisdiction—not to territorial sovereignty. The host state retains ownership and sovereignty; it simply cannot exercise certain powers over the embassy premises out of respect for diplomatic relations.

Practical Implications:

II. ARCHIPELAGIC DOCTRINE

QuAMTO Question 2: Definition and Implementation (2016 BAR)

QUESTION: Define the archipelagic doctrine of national territory, state its rationale and explain how it is implemented through the straight baseline method.

ANSWER:

Definition: By the term "archipelagic doctrine of national territory" is meant that the islands and waters of the Philippine Archipelago are unified in sovereignty, together with "all the territories over which the Philippines has sovereignty or jurisdiction."

EXPANDED ANALYSIS:

What is the Archipelagic Doctrine?

1. Conceptual Foundation

The archipelagic doctrine emphasizes the unity of land and waters. It treats the entire archipelago as an integrated unit rather than as fragmented individual islands surrounded by international waters.

Key Elements:

2. Historical Context

Bernas Commentary: Bernas notes that the archipelagic doctrine was a major concern during the 1973 Constitutional Convention. Before its international recognition, archipelagic states faced the problem of having international waters cutting through their island groups. This fragmented sovereignty and created security vulnerabilities.

The Philippines, along with Indonesia, was instrumental in advocating for international recognition of the archipelagic principle, which was eventually incorporated into the United Nations Convention on the Law of the Sea (UNCLOS).

Rationale of the Archipelagic Doctrine

This archipelagic doctrine, as described under Article I of the 1987 Constitution, draws its rationale from the status of the whole archipelago in sovereignty by which under Part IV of UNCLOS, the Philippines is defined as an Archipelagic State in Article 46:

a. "Archipelagic State" means a State constituted wholly by one or more archipelagos and may include other islands;

b. "Archipelago" means a group of islands including parts of islands, interconnecting waters and other natural features which are so closely interrelated that such islands, waters and other natural features form an intrinsic geographic, economic and political entity, or which historically have been regarded as such.

Why This Matters:

  1. Geographic Reality: The Philippines consists of over 7,000 islands. Without the archipelagic doctrine, international waters would separate these islands, fragmenting national sovereignty

  2. Economic Unity: The waters between islands are vital for inter-island commerce, fishing, and resource exploitation. The archipelagic doctrine ensures these waters remain under national control

  3. Political Unity: Recognition of the archipelago as a single entity reinforces national identity and territorial integrity

  4. Security: Treating inter-island waters as internal waters prevents foreign vessels from freely navigating between Philippine islands without permission

Implementation Through Straight Baseline Method

As an archipelagic state, the national territory is implemented by drawing its "straight archipelagic baselines" pursuant to Article 47 of UNCLOS which prescribes among its main elements, as follows:

1. Joining Outermost Points By "joining the outermost points of the outermost islands and drying reefs of the archipelago", including the main islands and an area in which the ratio of the area of the water to the land, including atolls, is between 1:1 and 9:1.

2. Length Limitation Mainly, the length of such baselines "shall not exceed 100 nautical miles."

3. General Configuration "The drawing of such baselines shall not depart to any appreciable extent from the general configuration of the archipelago."

How the Straight Baseline Method Works:

Step 1: Identify the outermost points of the outermost islands Step 2: Draw straight lines connecting these points Step 3: Ensure compliance with UNCLOS limitations (length, water-to-land ratio, general configuration) Step 4: All waters landward of these baselines become internal waters

Bernas Commentary: Bernas emphasizes that the straight baseline method was a revolutionary development in the law of the sea. Previously, territorial waters were measured from the low-water mark of each individual island, creating a patchwork of territorial and international waters. The straight baseline method allows archipelagic states to draw lines around the entire archipelago, unifying the territory.

This method was controversial when first proposed because maritime powers feared it would restrict freedom of navigation. However, UNCLOS balanced archipelagic state interests with navigation rights by providing for archipelagic sea lanes passage.

Philippine Implementation: The Philippines implemented the archipelagic doctrine through:

QuAMTO Question 3: Internal Waters vs. Territorial Sea (2009 BAR)

QUESTION: TRUE or FALSE. Explain your answer in not more than two (2) sentences: Under the archipelago doctrine, the waters around, between, and connecting the islands of the archipelago form part of the territorial sea of the archipelagic state.

ANSWER: FALSE.

EXPANDED ANALYSIS:

Why FALSE?

Constitutional Provision: Under Article I of the 1987 Constitution, the waters around, between and connecting the islands of the Philippines form part of its internal waters.

UNCLOS Provision: Under Article 49(1) of the U.N. Convention on the Law of the Sea, these waters do not form part of the territorial sea but are described as archipelagic waters.

Critical Distinction: Internal/Archipelagic Waters vs. Territorial Sea

1. Internal/Archipelagic Waters

2. Territorial Sea

3. Contiguous Zone

4. Exclusive Economic Zone (EEZ)

Why This Distinction Matters

Bernas Commentary: Bernas explains that the distinction between internal waters and territorial sea is crucial for understanding the extent of Philippine sovereignty. Internal waters are treated the same as land territory—foreign vessels have no right to enter without permission. In contrast, the territorial sea, while still under Philippine sovereignty, must accommodate the right of innocent passage.

Practical Example:

Common Misconception: Many assume that all waters within the baselines are "territorial sea." This is incorrect. The proper terminology distinguishes between:

  1. Internal/archipelagic waters (within baselines)
  2. Territorial sea (12 nautical miles from baselines)

Constitutional Significance: The Constitution's explicit statement that inter-island waters are "internal waters" was a deliberate assertion of maximum sovereignty. This was important for:

QuAMTO Question 4: General Definition (1989 BAR)

QUESTION: What do you understand by the archipelagic doctrine? Is this reflected in the 1987 Constitution?

ANSWER:

The archipelagic doctrine emphasizes the unity of land and islands surrounded by waters or a body of waters studded with islands. For this purpose, it requires that baselines be drawn by connecting the appropriate points of the outermost islands to encircle the islands within the archipelago. The waters on the landward side of the baselines regardless of breadth or dimensions are merely internal waters. The entire archipelago is regarded as one integrated unit instead of being fragmented into so many thousand islands.

Constitutional Reflection:

Yes, the archipelagic doctrine is reflected in Article I(1), 1987 Constitution which provides that:

EXPANDED ANALYSIS:

Evolution of the Archipelagic Doctrine in Philippine Constitutions

1935 Constitution: The 1935 Constitution defined Philippine territory by reference to the Treaty of Paris (1898), Treaty of Washington (1900), and Treaty with Great Britain (1930). It did not explicitly embrace the archipelagic doctrine.

Bernas Commentary: Bernas notes that the 1935 Constitution's definition was designed primarily to bind the United States to preserve Philippine territorial integrity. Since the Constitution required U.S. Presidential approval, including a territorial definition was meant to prevent American dismemberment of Philippine territory.

1973 Constitution: The 1973 Constitution was the first to explicitly incorporate the archipelagic doctrine. Article I stated:

"The waters around, between and connecting the islands of the archipelago, irrespective of their breadth and dimensions, form part of the internal waters of the Philippines."

This was a bold assertion because, at the time, the archipelagic doctrine was not yet universally accepted in international law.

1987 Constitution: The 1987 Constitution retained the 1973 provision almost verbatim, with minor stylistic changes. The retention signified:

  1. Continued commitment to the archipelagic principle
  2. Consistency with UNCLOS (1982), which by then recognized archipelagic states
  3. Educational value—teaching Filipinos about the nature of Philippine territory

Significance of "Regardless of Their Breadth and Dimensions"

This phrase is crucial. It means:

Bernas Commentary: Bernas emphasizes that this provision was designed to prevent arguments that certain inter-island waters were "too wide" to be considered internal waters. The Constitution settles the matter definitively—all inter-island waters are internal waters.

International Law Context

UNCLOS Recognition: The 1982 United Nations Convention on the Law of the Sea (UNCLOS) formally recognized the concept of archipelagic states. Part IV of UNCLOS (Articles 46-54) codified the archipelagic doctrine that the Philippines had long advocated.

Philippine Ratification: The Philippines ratified UNCLOS in 1984, making the Convention part of domestic law. R.A. 9522 (2009) further aligned Philippine baselines with UNCLOS requirements.

Relationship Between Constitution and UNCLOS:

The Constitution and UNCLOS complement each other:

Bernas Commentary: Bernas notes that the 1986 Constitutional Commission debated extensively whether to reference UNCLOS explicitly in the Constitution. Ultimately, they decided that the Constitution should make a general assertion while leaving specific implementation to legislation. This allows flexibility as international law evolves.

Practical Applications

1. Maritime Boundaries: The archipelagic doctrine affects how the Philippines measures its maritime zones:

2. Navigation Rights:

3. Resource Exploitation:

4. National Security:

III. HISTORICAL AND THEORETICAL FOUNDATIONS

Why Include a Territorial Definition in the Constitution?

Bernas Commentary:

Bernas provides extensive historical analysis of why Philippine constitutions include territorial definitions, noting that this is unusual—most constitutions do not define national territory.

1935 Constitution Rationale

Unique Purpose: The 1935 Constitution had a special reason for defining national territory. To be effective, the Constitution had to be accepted by the President of the United States. Since there was fear that the U.S. might dismember Philippine territory, delegates believed that including a territorial definition would prevent this.

Logic: If the U.S. President approved a Constitution defining Philippine territory, the U.S. would be bound to preserve that territory's integrity.

Bernas Observation: This reasoning was "valid for strengthening the force of our territorial definition as municipal law. However, they did not prove that a constitutional definition would strengthen Philippine legal position in international law."

1973 Constitution Rationale

No special international reason existed for including a territorial definition in 1973. However, delegates argued it was necessary for:

  1. Preservation of national wealth
  2. National security
  3. Manifestation of solidarity as a people
  4. Most importantly: Projection of Philippine adherence to the archipelagic principle

Bernas Observation: The 1973 definition served more of a political and educational purpose than a strictly legal one.

1987 Constitution Rationale

Bernas Commentary: The 1986 Constitutional Commission debates largely repeated the 1973 arguments. In the end, there was recognition that:

  1. An article on national territory has educational value
  2. It would be difficult to explain why, after 1935 and 1973 provisions, the new Constitution should omit one
  3. The archipelagic doctrine needed constitutional recognition

Key Insight: "Although the 1986 Constitutional Commission spent a considerable amount of time on Article I, in the end the provision that emerged was in substance a copy of its 1973 counterpart."

IV. COMPONENTS OF NATIONAL TERRITORY

A. Philippine Archipelago

What/Where is the Philippine Archipelago?

Although the Constitution does not explicitly reference the treaties, the Philippine archipelago is delineated by:

  1. Treaty of Paris (December 10, 1898) - Spain ceded the Philippines to the United States
  2. Treaty of Washington (November 7, 1900) - Additional islands ceded
  3. Treaty with Great Britain (January 2, 1930) - Further territorial clarification

Bernas Commentary: Bernas explains that the 1973 and 1987 Constitutions deliberately omitted specific mention of these treaties because delegates wanted to "erase every possible trace of our colonial history from the organic document." However, these treaties remain the historical basis for delimiting the archipelago.

Why This Matters: Understanding the treaty basis is essential for:

B. "All Other Territories Over Which the Philippines Has Sovereignty or Jurisdiction"

Change from 1973: The 1973 Constitution used: "all other territories belonging to the Philippines by historic right or legal title"

The 1987 Constitution changed this to: "all other territories over which the Philippines has sovereignty or jurisdiction"

Why the Change?

Bernas Commentary: The debates were "prolonged and emotionally intense" and focused primarily on avoiding the impression of constitutional abandonment of the Philippine claim to Sabah.

Sabah Controversy:

What's Included? This clause includes:

  1. Current territories: Any territory presently under Philippine sovereignty
  2. Future acquisitions: Any territory that might in the future belong to the Philippines through internationally accepted modes of acquiring territory
  3. Administrative territories: All territory over which the Philippine Government exercises jurisdiction

C. Terrestrial, Fluvial, and Aerial Domains

1. Terrestrial Domain

2. Fluvial Domain

3. Aerial Domain

Bernas Commentary: The aerial domain is based on the 1944 Chicago Convention on International Civil Aviation, which entered into force in 1974. Article 1 states: "The contracting States recognize that every State has complete and exclusive sovereignty over the airspace above its territory."

Outer Space Limitation: Sovereignty over airspace extends only until outer space begins. While there's no definitive answer on where airspace ends and outer space begins, different authorities suggest 50-100 miles from earth. Technological capabilities of conventional aircraft help determine this boundary.

D. Maritime Zones

1. Territorial Sea

2. Contiguous Zone

3. Exclusive Economic Zone

4. Continental Shelf

5. Insular Shelves

Bernas Commentary: The 1973 Constitution had a separate provision (Section 5) allowing the National Assembly to define control over the contiguous zone and superjacent waters of the continental shelf. This was based on the Geneva Conventions of 1958. The 1987 Constitution integrates these concepts directly into Article I.

V. KEY CONSTITUTIONAL PRINCIPLES

1. Unity of Territory

The archipelagic doctrine treats all islands and waters as a unified whole, not separate entities. This principle prevents fragmentation of sovereignty.

2. Completeness of Sovereignty

The Philippines exercises complete sovereignty over internal/archipelagic waters, territorial sea, and airspace. In maritime zones beyond, there are varying degrees of sovereign rights.

3. Flexibility for Future Acquisitions

The phrase "all other territories over which the Philippines has sovereignty or jurisdiction" allows for future territorial acquisitions through recognized international law methods.

4. Compliance with International Law

The constitutional definition exists within the framework of international law, particularly UNCLOS. The Constitution asserts Philippine rights while recognizing international obligations.

VI. RELATIONSHIP BETWEEN CONSTITUTION AND INTERNATIONAL LAW

Constitution as Municipal Law

Bernas Commentary: "A constitution is municipal law. As such, it binds only the nation promulgating it. Hence, a definition of national territory in the constitution will bind internationally only if it is supported by proof that can stand in international law."

Key Principles:

1. Municipal vs. International Law

2. Self-Limitation The Constitution cannot create territorial rights not recognized by international law. It can only assert rights that can be defended internationally.

3. Incorporation Clause Section 2, Article II: "The Philippines... adopts the generally accepted principles of international law as part of the law of the land."

This means:

Bernas Commentary: "The silence of a constitution regarding the territorial limits of a sovereignty does not deprive such sovereignty of any portion of territory it is entitled to under international law. Neither, however, does a constitutional definition of territory have the effect of legitimizing a territorial claim not founded on some legal right protected by international law."

UNCLOS and the Constitution

Complementary Relationship:

Constitution:

UNCLOS:

R.A. 9522:

Why Both Are Necessary:

The Constitution alone cannot define territorial waters in a way binding on other states. International law, through UNCLOS, provides the necessary recognition. The Constitution asserts Philippine sovereignty while UNCLOS provides the legal framework for international acceptance.

VII. CONTEMPORARY ISSUES

West Philippine Sea/South China Sea Disputes

Application of Archipelagic Doctrine:

The archipelagic doctrine and baselines are crucial in the Philippines' territorial disputes:

1. Baseline Determination:

2. EEZ Claims:

3. Nine-Dash Line:

Bernas Observation: While the Constitution provides domestic legal basis, resolution of these disputes ultimately depends on international law and diplomatic negotiations.

Environmental Protection

Constitutional Basis: The territorial waters clause provides constitutional foundation for:

Connection to Article II: Section 16, Article II: "The State shall protect and advance the right of the people to a balanced and healthful ecology..."

This, combined with Article I's territorial definition, gives the Philippines authority to:

Resource Exploitation

Sovereignty Over Resources:

The territorial definition establishes Philippine sovereignty over:

Constitutional Limitations:

Constitutional Significance

Bernas' Final Observations:

  1. Educational Function: The territorial definition teaches Filipinos about the nature and extent of Philippine territory

  2. Political Statement: Asserts Philippine sovereignty and territorial integrity

  3. Legal Foundation: Provides constitutional basis for territorial claims, though international law recognition remains necessary

  4. Historical Continuity: Maintains connection to pre-independence territorial understanding while adapting to modern international law

Integration with Other Constitutional Provisions

Article II (Declaration of Principles):

Article XII (National Economy and Patrimony):

Article XIII (Social Justice and Human Rights):

X. CONCLUSION

Why Article I Matters

The National Territory provision is not merely descriptive—it is a fundamental assertion of Philippine sovereignty and identity. Understanding Article I requires:

  1. Historical Perspective: Knowing the evolution from colonial treaties to constitutional assertion
  2. International Law Context: Understanding UNCLOS and the archipelagic doctrine's development
  3. Practical Application: Recognizing how territorial definitions affect jurisdiction, resources, and international relations
  4. Constitutional Integration: Seeing connections to other constitutional provisions on sovereignty, economy, and environment

Bernas' Ultimate Insight:

While the Constitution makes vital assertions about Philippine territory, these assertions gain force from:

The Constitution provides the domestic legal foundation; international law provides the framework for recognition; and actual governance makes sovereignty real.

Final Takeaway

Article I is brief but profound. Its few sentences encapsulate:

Mastering Article I means understanding not just constitutional text, but the intersection of history, international law, and national sovereignty.
