Umali vs. COMELEC

The conversion of a component city into a highly urbanized city constitutes a substantial alteration of boundaries under Section 10, Article X of the Constitution, requiring the participation of all qualified registered voters of the political units directly affected — including the mother province — in the plebiscite called for that purpose. Section 453 of the Local Government Code must be construed in harmony with this constitutional mandate, the phrase "qualified voters therein" being interpreted to mean the qualified voters not only of the city proposed for conversion but also of the political units directly affected.

Petitioner Aurelio M. Umali is the Governor of Nueva Ecija, the mother province within which Cabanatuan City is geographically located as a component city. Private respondent Julius Cesar Vergara is the city mayor of Cabanatuan. The dispute arises from the interplay between Section 10, Article X of the 1987 Constitution — which requires plebiscite approval by the "political units directly affected" whenever a province, city, municipality, or barangay is created, divided, merged, abolished, or its boundaries substantially altered — and Section 453 of the Local Government Code (LGC), which governs the President's duty to declare a city as highly urbanized upon ratification "by the qualified voters therein." The constitutional provision delegates legislative power over local government units subject to twin safeguards: compliance with LGC criteria and plebiscite approval. Section 453, in turn, delegates to the President the ministerial function of declaring a city as highly urbanized once the requirements under Section 452 are met, automatically triggering a plebiscite.

On July 11, 2011, the Sangguniang Panglungsod of Cabanatuan City passed Resolution No. 183-2011, requesting the President to declare the conversion of Cabanatuan City from a component city of Nueva Ecija into a highly urbanized city (HUC). The President acceded, issuing Presidential Proclamation No. 418, Series of 2012, which proclaimed Cabanatuan City as an HUC subject to ratification in a plebiscite as provided under Section 453 of the Local Government Code of 1991.

Acting on the proclamation, the COMELEC issued Minute Resolution No. 12-0797 on September 11, 2012, resolving that only registered residents of Cabanatuan City should participate in the plebiscite. The COMELEC based this ruling on Section 453 of the LGC, citing prior conversion cases involving Puerto Princesa City in Palawan, Tacloban City in Southern Leyte, and Lapu-Lapu City in Cebu, where only the residents of the city proposed for conversion were allowed to vote. Petitioner Aurelio M. Umali, Governor of Nueva Ecija, filed a Verified Motion for Reconsideration, maintaining that the conversion would necessarily and directly affect the mother province. He argued that Section 453 should be read in conjunction with Section 10, Article X of the Constitution, which requires plebiscite approval by the "political units directly affected," and that the phrase "qualified voters therein" in Section 453 should be interpreted to include the voters of all units directly affected, not just those in the component city proposed for upgrade. Private respondent Julius Cesar Vergara, city mayor of Cabanatuan, opposed the motion on the ground that Section 10, Article X does not apply to conversions and that Section 453, as couched, allows only the qualified voters of Cabanatuan City to vote.

After a hearing on October 4, 2012, the COMELEC En Banc ruled by a vote of 5-2 in favor of respondent Vergara through Minute Resolution No. 12-0925 dated October 16, 2012, denying the motion for reconsideration and scheduling the plebiscite with only registered residents of Cabanatuan City to participate. Governor Umali thereupon filed a Petition for Certiorari with prayer for injunctive relief before the Supreme Court, docketed as G.R. No. 203974, reiterating the same arguments raised before the poll body. The COMELEC, through the Office of the Solicitor General, maintained in its Comment that Cabanatuan City was merely being converted and that no political unit would be created, merged, or removed, and no boundaries altered; the conversion would merely reinforce the powers already exercised by the city. Private respondent Vergara adopted the COMELEC's Comment.

Meanwhile, on October 25, 2012, the COMELEC promulgated Resolution No. 9543, setting the plebiscite for December 1, 2012. A certain Dr. Rodolfo B. Punzalan filed a Petition for Declaratory Relief before the RTC, Branch 40 in Palayan City, praying that Minute Resolution No. 12-0797 be declared unconstitutional and that all qualified voters of Nueva Ecija be included in the plebiscite. On October 19, 2012, the RTC granted a TRO. The COMELEC suspended preparations on November 6, 2012, and the plebiscite was rescheduled to give way to the May 13, 2013 national elections. After the 2013 elections, the COMELEC issued Resolution No. 1353 scheduling the plebiscite to January 25, 2014, but the Supreme Court issued a TRO on January 15, 2014.

Separately, petitioner J.V. Bautista filed a Petition for Mandamus on December 3, 2012, docketed as G.R. No. 204371, praying that the COMELEC be ordered to schedule the plebiscite either on December 15 or 22, 2012, arguing that the RTC's TRO had expired and that the duty to hold the plebiscite had become mandatory and ministerial under the 120-day requirement from the President's declaration. The COMELEC countered that mandamus would not issue to enforce a right in substantial dispute and relied on Section 5 of the Omnibus Election Code to justify the postponements. The two petitions were consolidated on March 18, 2014.

• Constitutional Basis for Plebiscite Participation: Petitioner Umali argued that Section 453 of the LGC should be interpreted in conjunction with Section 10, Article X of the Constitution, which requires plebiscite approval by the "political units directly affected." He maintained that while the conversion does not involve the creation or dissolution of a city, the spirit of the constitutional provision calls for the people of the LGU directly affected to vote whenever there is a material change in their rights and responsibilities.
• Interpretation of "Qualified Voters Therein": Petitioner Umali contended that the phrase "qualified voters therein" in Section 453 of the LGC should be construed to refer to the qualified voters of the units directly affected by the conversion, not just those in the component city proposed to be upgraded, and he enumerated the adverse effects of the conversion on the political and economic rights of the province as a whole.
• Ministerial Duty to Hold Plebiscite: Petitioner Bautista argued that since the TRO issued by the RTC had expired, the COMELEC's duty to hold the plebiscite had become mandatory and ministerial, and that the delay was inexcusable given the requirement that the plebiscite be held within 120 days from the date of the President's declaration.

• Section 10, Article X Inapplicable to Conversions: Private respondent Vergara argued that Section 10, Article X of the Constitution does not apply to conversions, which is the meat of the matter, and that the specific provision of the LGC, Section 453, allows only the qualified voters of Cabanatuan City to vote in the plebiscite.
• Prior Precedent of Santiago City: Private respondent Vergara pointed out that when Santiago City was converted in 1994 from a municipality to an independent component city pursuant to RA 7720, the plebiscite was limited to the registered voters of the then municipality of Santiago.
• No Alteration of Political Units: The COMELEC, through the OSG, maintained that Cabanatuan City was merely being converted and that the political unit directly affected would only be the city itself; no political unit would be created, merged, or removed, and no boundaries would be altered. The conversion would merely reinforce the powers already exercised by the city.
• Mandamus Improper: The COMELEC argued that mandamus would not issue to enforce a right in substantial dispute, and that there was no clear showing of petitioner Bautista's entitlement to the relief sought. It likewise relied on Section 5 of the Omnibus Election Code to justify the postponements, citing incidents of violence during the plebiscite period.

• Applicability of Section 10, Article X: Whether the conversion of a component city into a highly urbanized city falls within the scope of Section 10, Article X of the Constitution, which governs the creation, division, merger, abolition, or substantial alteration of boundaries of local government units.
• Harmonization of Section 453 with the Constitution: Whether the phrase "qualified voters therein" in Section 453 of the LGC should be construed to include the qualified voters of the entire province, in order to harmonize the provision with Section 10, Article X of the Constitution.
• Directly Affected Political Units: Whether the entire province of Nueva Ecija is "directly affected" by the conversion of Cabanatuan City into an HUC, such that its qualified registered voters should participate in the plebiscite.
• Mandamus: Whether the COMELEC may be compelled by mandamus to hold the plebiscite.

• Applicability of Section 10, Article X: Yes. The conversion of a component city into a highly urbanized city constitutes a substantial alteration of boundaries within the meaning of Section 10, Article X of the Constitution, as it entails a change in both the physical and political boundaries of the LGUs involved.
• Harmonization of Section 453 with the Constitution: Yes. The phrase "qualified voters therein" in Section 453 of the LGC must be construed to mean the qualified voters not only of the city proposed for conversion but also of the political units directly affected, in order to harmonize the provision with Section 10, Article X and avoid unconstitutionality.
• Directly Affected Political Units: Yes. The entire province of Nueva Ecija is directly affected by the conversion, given the substantial reduction in its territorial jurisdiction, internal revenue allotment, taxing power, and political supervision over the city, warranting the participation of all its qualified registered voters in the plebiscite.
• Mandamus: Dismissed as moot. Resolution of the certiorari petition necessarily settled the question of who should participate, rendering the mandamus petition academic.

• Applicability of Section 10, Article X: The Court first established that the power to create, divide, merge, abolish, or substantially alter the boundaries of LGUs is essentially legislative in nature, and that Section 10, Article X of the Constitution permits the delegation of this power subject to twin safeguards: compliance with LGC criteria and plebiscite approval. Section 453 of the LGC delegates to the President the ministerial function of declaring a city as highly urbanized once the requirements under Section 452 are met, automatically triggering a plebiscite. The source of this delegation is Section 10, Article X itself. Applying the reasoning in Miranda vs. Aguirre, which held that the downgrading of an independent component city into a component city falls within the purview of Section 10, Article X, the Court found that conversions — whether upward or downward — result in material changes in the economic and political rights of the LGUs and people affected. Furthermore, the conversion of a component city into an HUC constitutes a substantial alteration of boundaries, because "boundaries" should not be limited to physical metes and bounds but also includes political boundaries — the demarcation lines between political subdivisions where one LGU's exercise of corporate power ends and another's begins. Article 12(c) of the LGC's Implementing Rules and Regulations provides that the conversion of a component city into an HUC makes it independent of the province where it is geographically located. Nueva Ecija stands to lose 282.75 sq. km. of its territorial jurisdiction — nearly 5% of its 5,751.3 sq. km. area — which sufficiently satisfies the requirement that the alteration be "substantial."

• Harmonization of Section 453 with the Constitution: The Court applied the cardinal principle of constitutional supremacy: a statute should be construed in harmony with, rather than in repugnance to, the Constitution. If the plain meaning of "qualified voters therein" in Section 453 were taken to refer only to the city's voters, the provision would clash with the explicit constitutional requirement that voters in the "political units directly affected" shall participate. Such a construction must be avoided. The Court also found that Section 10 of the LGC, entitled "Plebiscite Requirement," is the applicable provision on the conduct of plebiscites, requiring a majority of votes cast in the political unit or units directly affected, while Section 453, entitled "Duty to Declare Highly Urbanized Status," merely mandates the President to make the declaration upon proper application and ratification. Thus, Section 10 of the LGC prevails over Section 453 on the plebiscite requirement. The phrase "qualified voters therein" in Section 453 was construed to mean the qualified voters of all political units directly affected by the conversion, harmonizing the provision with Section 10, Article X. The Court rejected respondents' reliance on prior plebiscites in Puerto Princesa, Tacloban, and Lapu-Lapu Cities, noting that the issue of voter participation was never properly raised in those cases and that the operative fact doctrine preserves the validity of those past conversions.

• Directly Affected Political Units: Drawing on Tan vs. COMELEC and Padilla vs. COMELEC, the Court held that the LGUs whose boundaries are altered and whose economy would be affected are entitled to participate in the plebiscite. The phrase "political units directly affected" contemplates a plurality of political units, as confirmed by the deliberations of the Constitutional Commission and the Senate. The Court then examined the economic and political impacts on Nueva Ecija. Economically, the province would suffer a substantial reduction in its Internal Revenue Allotment (IRA) — estimated at ₱125,550,744.85 — due to the decrease in population and land area used as multipliers under Section 285 of the LGC. The province would also lose shares in provincial taxes imposed in Cabanatuan City, as Section 151 of the LGC provides that taxes levied by HUCs accrue to them. The income criterion for an HUC (₱50,000,000) exceeds the income requirement for the creation of a province (₱20,000,000), meaning the separation would leave a crippling effect on the province's operations. Politically, the province would lose administrative supervision over the city under Section 4, Article X of the Constitution, as HUCs are independent of the province under Section 12, Article X. The province would be divested of the power to review executive orders, approve ordinances, and adjudicate disciplinary cases involving city officials. The registered voters of the city would no longer be entitled to vote for or be voted upon as provincial officials. In light of these material changes in both economic and political rights, the entire province of Nueva Ecija was held to be directly affected, and all its qualified registered voters were entitled to participate in the plebiscite.

• Mandamus: The Court noted that resolving the certiorari petition either way would necessarily render the mandamus petition moot, as the COMELEC would ultimately be ordered to hold the plebiscite, the only variation being the participants. The mandamus petition was accordingly dismissed.

• Substantial Alteration of Boundaries — The phrase "substantial alteration of boundaries" under Section 10, Article X of the Constitution is not limited to physical or geographical boundaries (metes and bounds) but also encompasses political boundaries — the demarcation lines between political subdivisions where one LGU's exercise of corporate power ends and another's begins. The conversion of a component city into an HUC, which severs the city from the mother province and reduces the latter's territorial jurisdiction, constitutes a substantial alteration of boundaries. In this case, Nueva Ecija's loss of 282.75 sq. km. — nearly 5% of its total area — satisfied the "substantial" qualifier.

• Political Units Directly Affected — The phrase "political units directly affected" under Section 10, Article X of the Constitution contemplates a plurality of political units, not merely the unit proposed for creation, division, merger, abolition, or conversion. LGUs whose boundaries are altered and whose economy and political rights would be affected are entitled to participate in the plebiscite. The deliberations of the Constitutional Commission and the Senate confirmed that the deletion of the words "unit or" from the 1973 Constitution formulation was intended to ensure that all units affected — including the parent province — participate.

• Constitutional Supremacy in Statutory Construction — A statute must be construed in harmony with the Constitution. If a provision is fairly susceptible of two interpretations, that which avoids unconstitutionality must be adopted, even if it requires disregarding the more usual or apparent import of the language used. Section 453's phrase "qualified voters therein" was thus construed to include voters of all directly affected political units to avoid conflict with Section 10, Article X.

• Operative Fact Doctrine — The actual existence of a statute or executive act prior to a judicial determination of unconstitutionality is an operative fact and may have consequences which cannot always be erased by a new judicial declaration. The Court invoked this doctrine to preserve the validity of prior HUC conversions in Puerto Princesa, Tacloban, and Lapu-Lapu Cities, where the issue of voter participation had never been raised.

• "A close analysis of the said constitutional provision will reveal that the creation, division, merger, abolition or substantial alteration of boundaries of local government units involve a common denominator - - - material change in the political and economic rights of the local government units directly affected as well as the people therein." — This passage, quoted from Miranda vs. Aguirre, articulates the rationale underlying the plebiscite requirement and explains why conversions — though not expressly enumerated in Section 10, Article X — fall within its ambit.

• "To limit the plebiscite to only the voters of the areas to be partitioned and seceded from the province is as absurd and illogical as allowing only the secessionists to vote for the secession that they demanded against the wishes of the majority and to nullify the basic principle of majority rule." — This passage captures the Court's reasoning on why excluding the mother province's voters from the plebiscite would undermine the democratic principle underlying the constitutional plebiscite requirement.

• "The phrase 'boundaries' should not be limited to the mere physical one, referring to the metes and bounds of the LGU, but also to its political boundaries. It also connotes a modification of the demarcation lines between political subdivisions, where the LGU's exercise of corporate power ends and that of the other begins." — This defines the expanded meaning of "boundaries" under Section 10, Article X, establishing that political severance qualifies as a substantial alteration even without a change in physical metes and bounds.

• Miranda vs. Aguirre, G.R. No. 133064, September 16, 1999, 314 SCRA 603 — Controlling precedent applied by analogy. Held that the downgrading of an independent component city into a component city falls within the purview of Section 10, Article X of the Constitution, requiring plebiscite ratification. RA 8528 was declared unconstitutional for downgrading Santiago City without a plebiscite. The Court extended its rationale to upward conversions (component city to HUC), finding that both result in material changes in political and economic rights.

• Tan vs. COMELEC, No. L-73155, July 11, 1986, 142 SCRA 727 — Followed. Held that in the division of Negros Occidental for the creation of Negros del Norte, the LGUs whose boundaries are altered and whose economy would be affected are entitled to participate in the plebiscite. Established that a plurality of political units may be "directly affected."

• Padilla vs. COMELEC, G.R. No. 103328, October 19, 1992, 214 SCRA 735 — Followed. Affirmed the ruling in Tan that the phrase "political units directly affected" contemplates a plurality of political units, notwithstanding the deletion of the words "unit or" from the 1973 Constitution formulation.

• Fernandez vs. Cuerva, No. L-21114, November 28, 1967, 21 SCRA 1095 — Cited for the orthodox view that an unconstitutional act is not a law, confers no rights, imposes no duties, and affords no protection, and for the operative fact doctrine. Also cited for the principle that a law should be construed in harmony with the Constitution.

• Section 10, Article X, 1987 Constitution — Requires that no province, city, municipality, or barangay may be created, divided, merged, abolished, or its boundary substantially altered except in accordance with LGC criteria and subject to approval by a majority of votes cast in a plebiscite in the political units directly affected. Held to govern the conversion of a component city into an HUC, as such conversion constitutes a substantial alteration of boundaries.

• Section 453, Local Government Code (RA 7160) — Mandates the President to declare a city as highly urbanized within thirty days after it meets the minimum requirements under Section 452, upon proper application and ratification in a plebiscite by the "qualified voters therein." Construed in harmony with Section 10, Article X, the phrase "qualified voters therein" was interpreted to include voters of all political units directly affected, not just those of the city.

• Section 10, Local Government Code — Entitled "Plebiscite Requirement," provides that no creation, division, merger, abolition, or substantial alteration of boundaries of LGUs shall take effect unless approved by a majority of votes cast in a plebiscite in the political unit or units directly affected. Held to prevail over Section 453 on the plebiscite requirement.

• Section 6, Local Government Code — Authorizes the creation, division, merger, abolition, or substantial alteration of boundaries of LGUs by law or ordinance, subject to limitations prescribed in the Code. Recognized as a valid delegation of legislative power under Section 10, Article X.

• Section 285, Local Government Code — Prescribes the formula for IRA allocation based on population (50%), land area (25%), and equal sharing (25%). Applied to demonstrate that Nueva Ecija would suffer a substantial IRA reduction upon Cabanatuan City's conversion, estimated at ₱125,550,744.85.

• Section 151, Local Government Code — Provides that taxes, fees, and charges levied by HUCs and independent component cities shall accrue to them. Applied to show that the province would lose its taxing jurisdiction and corresponding shares in local tax collections upon the city's conversion.

• Sections 4 and 12, Article X, 1987 Constitution — Section 4 provides for the President's general supervision over local governments and the provinces' supervision over component cities and municipalities. Section 12 provides that HUCs shall be independent of the province. Applied to demonstrate the loss of provincial administrative supervision over Cabanatuan City upon conversion.

• Article 12(c), IRR of the Local Government Code — Provides that the conversion of a component city into an HUC shall make it independent of the province where it is geographically located. Relied upon to establish that the conversion entails a substantial alteration of political boundaries.

Antonio T. Carpio, Teresita J. Leonardo-De Castro, Arturo D. Brion, Diosdado M. Peralta, Lucas P. Bersamin, Mariano C. Del Castillo, Jose Portugal Perez, Bienvenido L. Reyes, and Estela M. Perlas-Bernabe concurred in the decision. Roberto A. Abad took no part.

• Marvic Mario Victor F. Leonen — Justice Leonen dissented and issued a separate opinion. Chief Justice Ma. Lourdes P. A. Sereno, Justice Martin S. Villarama, Jr., and Jose Catral Mendoza joined the dissent. The text of the dissenting opinion is not included in the provided case material, precluding a summary of its specific legal reasoning.
