Facts

• Petitioners challenged Sections 3(a), 3(b), 5, 6, 7, 8, 52(i), 57, 58, 59, 63, 65, and 66 of IPRA and related Implementing Rules provisions directly before the Supreme Court. (Isagani Cruz and Cesar Europa sued as citizens and taxpayers, in prohibition and mandamus, against R.A. No. 8371 — enacted 29 October 1997 — and the NCIP's 1998 implementing rules. No concrete land dispute underlay the petition, which is why everything said here about the Regalian Doctrine is said in the abstract.)
• On October 13, 1998, respondent NCIP filed its Comment defending IPRA's constitutionality.
• On October 19, 1998, the DENR and DBM Secretaries, through the OSG, filed a consolidated Comment taking the intermediate position that IPRA is partly unconstitutional insofar as it grants ownership of natural resources to indigenous peoples. Even the Government would not defend the law whole, and it narrowed its objection to natural resources — which is exactly where the Regalian Doctrine bites hardest under Section 2, Article XII.
• Between November 1998 and March 1999, several groups — Senator Flavier with 112 indigenous-peoples' organizations, the Commission on Human Rights, and the Ikalahan Indigenous People with the Haribon Foundation — successfully moved to intervene in defense of IPRA.
• Oral arguments were heard April 13, 1999, followed by memoranda.
• On deliberation, the Court split seven-to-seven: Justice Kapunan's opinion (joined by the Chief Justice and Justices Bellosillo, Quisumbing, and Santiago), plus the separate opinions of Justices Puno and Mendoza, voted to dismiss and sustain IPRA. The tie is the holding. Seven-seven under Rule 56, Section 7 dismisses the petition and leaves IPRA standing, but lays down no doctrine at all on how ancestral domain sits with the Regalian Doctrine — read the separate opinions for argument, never for authority.
• The separate opinions of Justices Panganiban and Vitug (joined by Justices Melo, Pardo, Buena, Gonzaga-Reyes, and De Leon) voted to grant the petition.
• Redeliberation left the vote unchanged.
• The Court issued the instant Per Curiam Resolution on December 6, 2000.

Ruling

Ratio

• Because the Resolution records a tied en banc vote, its operative reasoning is procedural.
• It applies Rule 56§, Section 7 as its sole basis: where the Court en banc is equally divided on an original petition and the deadlock survives redeliberation, the petition is dismissed.
• That single element was met — the vote was seven-to-seven, and "after redeliberation, the voting remained the same."
• Substantively, the Resolution records without resolving the opposing positions: the dismiss-bloc (Kapunan, joined by four justices, plus Puno and Mendoza separately) treated the ancestral domain provisions as consistent with Section 2, Article XII, with Puno excepting Section 57 as limited to "large-scale exploitation of natural resources" and to be read with Section 2, Article XII.
• The grant-bloc (Panganiban and Vitug, joined by five justices) found Sections 3(a)(b), 5, 6, 7(a)(b), 8, and, per Vitug, 57, unconstitutional for vesting resource ownership in ICCs/IPs contrary to Regalian ownership.

• The Regalian Doctrine is the premise, and native title is its recognized exception. Puno traces jura regalia from the Spanish decrees embracing "the feudal theory" that all lands were held from the Crown, through the Philippine Bill of 1902, to Section 2, Article XII of the 1987 Constitution — then records that "[w]hile our legal tradition subscribes to the Regalian Doctrine reinstated in Section 2, Article XII of the 1987 Constitution," our "decisional laws" have "made exception to the doctrine."
• The exception is the Cariño doctrine. It "was first laid down in the case of Cariño v. Insular Government" where "the court has recognized long occupancy of land by an indigenous member of the cultural communities as one of private ownership, which, in legal concept, is termed 'native title.' This ruling has not been overturned."
• Native title works by presumption, not by grant. Land held under native title consists of "pre-conquest rights to lands and domains which, as far back as memory reaches, have been held under a claim of private ownership by ICCs/IPs, have never been public lands and are thus indisputably presumed to have been held that way since before the Spanish Conquest." Hence: "Domains and lands held under native title are, therefore, indisputably presumed to have never been public lands and are private."
• That is what removes the conflict with the Regalian Doctrine. Because such land is presumed never to have entered the public domain, recognising it takes nothing from the State — no State grant is needed, and none is dispensed with. Puno accordingly distinguishes the two routes by which ICC/IP rights are held: "(1) by native title over both ancestral lands and domains; or (2) by torrens title under the Public Land Act and the Land Registration Act with respect to ancestral lands only."
• The contrary bloc rejected exactly this step. Panganiban and Vitug would have held Sections 3(a)(b), 5, 6, 7(a)(b), 8 (and, for Vitug, 57) unconstitutional precisely because, in their view, no statute may convert public dominion into ICC/IP property without a State grant, whatever the length of possession.
• Because neither view drew a majority, neither is doctrine; both are persuasive only.

Doctrine

• The binding holding is procedural: "[P]ursuant to Rule 56§, Section 7 of the Rules of Civil Procedure, the petition is DISMISSED" upon an unbroken equally divided vote. No majority doctrine on Section 2, Article XII's application to IPRA was laid down.

• This case cannot be cited for a holding that IPRA's ancestral domain provisions are constitutional, or unconstitutional, under the Regalian Doctrine — only for its procedural survival, and for the persuasive, non-binding value of the separate opinions.

• Classification: DIRECT as to subject matter, institutionally inconclusive as to result. Read the case at two levels, and do not collapse them:
• What it holds. Only the procedural rule on tied en banc votes — Rule 56§, Section 7. IPRA survives by default, not by adjudication.
• What it is assigned for. The Regalian Doctrine's single recognized exception: native title. Puno, J.'s Separate Opinion is the standard exposition of jura regalia's development in Philippine law and of the Cariño v. Insular Government exception, under which land held since before the Spanish conquest under a claim of private ownership is "indisputably presumed to have never been public lands and [is] private." That presumption, not any grant from the State, is what reconciles ancestral domain with Section 2, Article XII.
• How to recite it. State the Regalian premise, state the Cariño/native-title exception and its "never been public land" presumption, then state that the Court divided 7–7 so that no majority doctrine issued — the exception is settled by Cariño itself and by IPRA's own text, not by Cruz.

III. Arguments of the Parties

A. Petitioner / Prosecution

• Petitioner Isagani Cruz, Petitioner Cesar Europa, and the Solicitor General argued that Section 3(a), Section 3(b), Section 5, Section 6, Section 7, Section 8, Section 57, and Section 58 of Republic Act No. 8371 violate the Regalian Doctrine under Section 2, Article XII of the 1987 Constitution by unlawfully depriving the State of ownership over lands of the public domain and natural resources.
• The petitioners contended that the all-encompassing definitions of ancestral domains and ancestral lands include private lands, thereby violating the due process rights of private landowners.
• The petitioners asserted that the administrative relationship of the National Commission on Indigenous Peoples to the Office of the President as lateral but autonomous infringes upon the power of control of the President over executive departments under Section 17, Article VII of the 1987 Constitution.
• The Solicitor General specifically argued that any native title over ancestral lands was extinguished upon the ratification of the 1935 Constitution, and that the State restructured land ownership to assume full control and supervision over natural resources under the police power.

B. Respondent / Defense

• The National Commission on Indigenous Peoples and the intervenors argued that Republic Act No. 8371 is constitutional because ancestral domains and ancestral lands are private properties of indigenous cultural communities and do not constitute part of the public domain.
• The respondents contended that the ownership granted over ancestral domains is a limited form of ownership that does not include the right of alienation, and that the State retains ownership and full control over natural resources.
• The respondents asserted that the law fulfills the constitutional mandate to protect the rights of indigenous cultural communities to ancestral lands to ensure economic, social, and cultural well-being under Section 5, Article XII and Section 22, Article II of the 1987 Constitution.

C. Common Ground

• The adversarial parties did not stipulate to any common ground on the substantive issues of land ownership; however, both the petitioners and the respondents recognized that the Regalian Doctrine is a foundational concept of Philippine property law and that the 1987 Constitution requires the balancing of national development goals with the protection of indigenous rights.

IV. Issues

A. Main Issue

B. Secondary Issues

1. Whether the provisions of Republic Act No. 8371 defining the powers and jurisdiction of the National Commission on Indigenous Peoples and making customary law applicable to dispute settlements violate the due process clause of the 1987 Constitution.
2. Whether Rule VII, Part II, Section 1 of the Implementing Rules and Regulations of the National Commission on Indigenous Peoples violates the President's power of control over the Executive Department under Section 17, Article VII of the 1987 Constitution.

V. Ruling / Disposition

• A. MAIN ISSUE: NO. The Supreme Court dismissed the petition because the votes of the members of the Supreme Court were equally divided (7 to 7) after redeliberation. Consequently, the constitutionality of the challenged provisions of Republic Act No. 8371 was deemed upheld as valid under Rule 56§, Section 7 of the Rules of Civil Procedure. The separate opinions of Associate Justice Reynato S. Puno and Associate Justice Santiago M. Kapunan explained that ancestral lands and ancestral domains held under native title since time immemorial are private lands that never formed part of the public domain, making the Regalian Doctrine inapplicable.
• B. SECONDARY ISSUES:
  1. NO. The Supreme Court dismissed the petition due to the equal division of votes. The separate opinions of Associate Justice Reynato S. Puno and Associate Justice Santiago M. Kapunan clarified that the application of customary law is authorized under paragraph 2, Section 5, Article XII of the 1987 Constitution and applies only to disputes where all the parties are members of the same indigenous group, while procedural safeguards protect the due process rights of non-members.
  2. NO. The Supreme Court dismissed the petition due to the equal division of votes. The separate opinion of Associate Justice Santiago M. Kapunan explained that characterizing the National Commission on Indigenous Peoples as an independent agency under the Office of the President does not remove the commission from the President's administrative control and supervision.

Verbatim Dispositive Portion

"As the votes were equally divided (7 to 7) and the necessary majority was not obtained, the case was redeliberated upon. However, after redeliberation, the voting remained the same. Accordingly, pursuant to Rule 56§, Section 7 of the Rules of Civil Procedure, the petition is DISMISSED."

VI. Ratio Decidendi and Doctrines

A. Ratio Decidendi

• The capacity of the State to own or acquire property is the power of dominium, which served as the foundation for the feudal theory of jura regalia introduced through the Laws of the Indies.
• Under Section 2, Article XII of the 1987 Constitution, all public lands and natural resources are owned by the State, but this state ownership is subject to existing private rights.
• The United States Supreme Court in the landmark case of Cariño v. Insular Government established that long occupancy of land by indigenous members under a claim of private ownership since time immemorial is recognized as "native title".
• Lands held by virtue of native title are indisputably presumed to have been held in the same way since before the Spanish Conquest, and therefore, such lands are private and never formed part of the public domain.
• Because ancestral domains and ancestral lands are private properties of the Indigenous Cultural Communities and Indigenous Peoples, the recognition of native title under Republic Act No. 8371 does not violate the Regalian Doctrine.
• The right of ownership granted under Section 7(a) of Republic Act No. 8371 is limited to lands, bodies of water traditionally and actually occupied, sacred places, and traditional hunting and fishing grounds, and does not extend to the natural resources found on or under the land.
• The State retains ownership of all natural resources within the ancestral domains; thus, Section 1, Part II, Rule III of the Implementing Rules, which purports to grant ownership of "natural resources" to indigenous peoples, is unconstitutional and ultra vires.
• The limited rights of "management and use" over natural resources under Section 7(b) contemplate small-scale utilization for daily sustenance and survival, which is expressly permitted under paragraph 3, Section 2, Article XII of the 1987 Constitution.
• The "priority rights" granted to indigenous peoples under Section 57 for the large-scale development and exploitation of natural resources do not mean exclusive ownership, but rather a right of preference under which the State, as owner of the natural resources, may enter into co-production, joint venture, or production-sharing agreements with the indigenous communities or non-members under State control and supervision.
• Vested rights of ownership over ancestral lands and ancestral domains existed prior to the 1935, 1973, and 1987 Constitutions, and the constitutional protection of existing rights under the due process clause prevents the State from unilaterally extinguishing such private property rights.
• Section 3(a) of Republic Act No. 8371 merely defines the geographic extent and composition of ancestral domains for the purpose of delineation; the definition does not automatically convert natural resources into the private property of indigenous peoples.
• The concept of "private but community property" under Section 5 represents a communal character of ownership under customary law where the property belongs to all generations and cannot be sold, disposed, or destroyed, which coexists with the civil law concept.
• The National Commission on Indigenous Peoples acts as an additional administrative safeguard under Section 59, where the requirement of prior informed consent is not a grant of veto power over natural resource utilization, but an additional regulatory requirement to protect indigenous interests.

B. Doctrines/Rules

1. The Regalian Doctrine (Jura Regalia)

"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."

2. The Concept of Native Title

"Sec. 3 [l]. Native Title - refers to pre-conquest rights to lands and domains which, as far back as memory reaches, have been held under a claim of private ownership by ICCs/IPs, have never been public lands and are thus indisputably presumed to have been held that way since before the Spanish Conquest."

3. The Cariño Doctrine

"when, as far back as testimony or memory goes, the land has been held by individuals under a claim of private ownership, it will be presumed to have been held in the same way from before the Spanish conquest, and never to have been public land."

4. The Indigenous Concept of Ownership

"Sec. 5. Indigenous concept of ownership.- Indigenous concept of ownership sustains the view that ancestral domains and all resources found therein shall serve as the material bases of their cultural integrity. The indigenous concept of ownership generally holds that ancestral domains are the ICCs/IPs private but community property which belongs to all generations and therefore cannot be sold, disposed or destroyed. It likewise covers sustainable traditional resource rights."

C. Limitations/Exceptions

• Ban on Alienation of Ancestral Domains: Under the indigenous concept of ownership, ancestral domains are communally held for all generations and therefore cannot be sold, disposed, or destroyed. Individual ancestral lands may be transferred, but such transfers are strictly limited to members of the same Indigenous Cultural Communities or Indigenous Peoples and are subject to customary laws and a fifteen-year right of redemption.
• Exclusion of Natural Resources: Native title applies only to lands, bodies of water traditionally and actually occupied, sacred places, and traditional hunting and fishing grounds. The right of ownership does not extend to the natural resources, such as minerals, forests, or waters, found within the ancestral domains, which remain properties of the public dominion owned by the State under Section 2, Article XII of the 1987 Constitution.
• Preservation of Existing Vested Rights: Section 56 of Republic Act No. 8371 expressly provides that property rights within the ancestral domains already existing and/or vested upon the effectivity of the Act shall be recognized and protected, ensuring that Torrens titles held by non-indigenous landowners are not impaired.
• Primacy of Customary Law Limited: The application of customary law under Section 62 and Section 63 is limited to disputes concerning property rights or relations in determining the ownership and extent of ancestral domains where all the parties involved are members of the same indigenous group. When one of the parties to the dispute is a non-member, customary law does not apply, and the dispute must be resolved under the regular Rules of Procedure.

D. Topic Integration

VII. Separate Opinions

A. Separate Opinion of Associate Justice Artemio V. Panganiban (Concurring and Dissenting)

• Associate Justice Artemio V. Panganiban argued that Republic Act No. 8371 is unconstitutional insofar as the law recognizes rights of ownership over lands of the public domain and natural resources, which are owned by the State and cannot be alienated under Section 2, Article XII of the Constitution.
• The separate opinion of Associate Justice Artemio V. Panganiban rejected the contention that ancestral domains are not public lands, stating that such a sweeping statement places substantial portions of Philippine territory (amounting to one-third of the land and eighty percent of the natural wealth) outside the scope of the Constitution and beyond the reach of the Filipino people.
• Associate Justice Artemio V. Panganiban contended that the concept of native title in Cariño v. Insular Government was modified and superseded by the absolute terms of the 1935, 1973, and 1987 Constitutions, which declare that all public lands belong to the State.
• The separate opinion of Associate Justice Artemio V. Panganiban also asserted that the law abdicates the State's duty to take full control and supervision of natural resources by relinquishing the power to develop and manage those resources to the indigenous communities.

B. Separate Opinion of Associate Justice Jose C. Vitug (Dissenting)

• Associate Justice Jose C. Vitug opined that Section 3(a) and Section 7 of Republic Act No. 8371 virtually withdraw millions of hectares of ancestral domains from the public domain and cede virtual ownership and control over natural resources to the indigenous communities.
• The separate opinion of Associate Justice Jose C. Vitug concluded that these provisions exceed the context of the fundamental law and amount to an undue delegation and unacceptable abdication of State authority over a significant area of the country and its patrimony.
• Associate Justice Jose C. Vitug emphasized that the Constitution requires a careful balancing of interests between the specific needs of indigenous communities and the imperatives of national interest, and urged Congress to re-examine the law.
