Mariano, Jr. vs. Commission on Elections

The conversion of a municipality into a highly urbanized city via a special law is constitutional, and the territorial description therein need not strictly comply with the metes-and-bounds requirement of the Local Government Code when a bona fide boundary dispute exists, so long as the jurisdiction is reasonably ascertainable from existing boundaries.

Republic Act No. 7854, enacted in 1994, converted the Municipality of Makati into a highly urbanized city. The law was challenged before the Supreme Court via two consolidated petitions. Petitioners, including residents of Makati and an adjacent municipality (Taguig), as well as a senator, questioned the constitutionality of specific provisions concerning the city's territorial boundaries, the continuity of terms for incumbent officials, and the creation of a second legislative district.

• Nature of the Action: Two petitions were filed challenging the constitutionality of Republic Act No. 7854, "An Act Converting the Municipality of Makati Into a Highly Urbanized City to be known as the City of Makati."
• The Territorial Challenge: Petitioners argued that Section 2 of R.A. No. 7854, which described Makati's territory as comprising its "present territory" bounded by neighboring cities and municipalities, violated the Local Government Code's requirement that the land area of a new city be described by "metes and bounds, with technical descriptions." At the time of the law's passage, a territorial dispute over Fort Bonifacio between Makati and Taguig was under litigation.
• The Term Limit Challenge: Petitioners contended that Section 51 of the Charter, which stated the new city would "acquire a new corporate existence," unconstitutionally restarted the three-term limit for incumbent elective officials, specifically benefiting then-Mayor Jejomar Binay.
• The Legislative District Challenge: Petitioners assailed Section 52, which created a second legislative district for Makati. They argued that reapportionment could only be done via a general law, not a special charter; that the increase was not expressed in the bill's title; and that Makati's population (450,000 based on the 1990 census) did not justify two districts.

• Territorial Description: Petitioners maintained that the failure to describe Makati's territory by metes and bounds with technical descriptions rendered R.A. No. 7854 unconstitutional, as it violated mandatory provisions of the Local Government Code (Sections 7 and 450).
• Term Limits: Petitioners argued that Section 51's "new corporate existence" clause effectively erased the terms served by incumbent officials as municipal officials, allowing them to serve more than three consecutive terms as city officials, in violation of constitutional term limits.
• Legislative Districts: Petitioners argued that reapportionment must be done through a general apportionment law as mandated by the Constitution; that the creation of a new district was a subject not covered in the law's title; and that Makati's population did not meet the threshold for a second district.

• Territorial Description: The Solicitor General countered that the metes-and-bounds requirement was a tool to achieve the purpose of reasonably ascertaining a city's territory, not an end in itself. The description using common boundaries with neighboring LGUs was sufficient, especially given the pending court litigation over the boundary with Taguig.
• Term Limits: Respondents argued that the challenge was hypothetical, as it depended on contingent future events (Mayor Binay's candidacy and re-election).
• Legislative Districts: Respondents contended that the Constitution allows Congress to fix the number of representatives "by law," which includes special charters. They also argued the population requirement was met and the subject was germane to the law's title.

• Territorial Sufficiency: Whether Section 2 of R.A. No. 7854 is unconstitutional for failing to describe the city's territory by metes and bounds with technical descriptions.
• Actual Controversy (Term Limits): Whether the challenge to Section 51 of R.A. No. 7854 presents a justiciable case or controversy.
• Method of Reapportionment: Whether the creation of an additional legislative district for Makati via its city charter violates the constitutional requirement that reapportionment be made through a general law.
• Population Requirement: Whether the creation of a second district for Makati violates the constitutional population standard.
• One Title-One Subject Rule: Whether the inclusion of a reapportionment provision violates the constitutional requirement that every bill embrace only one subject expressed in its title.

• Territorial Sufficiency: The challenge was rejected. The Court ruled that the existence of a bona fide boundary dispute provided a legitimate reason for Congress to refrain from using a technical description. The description using established boundaries was sufficient to reasonably ascertain the city's territorial jurisdiction, complying with the spirit of the law.
• Actual Controversy (Term Limits): The Court found no actual case or controversy. The challenge was based on a series of hypothetical future events (Mayor Binay's candidacy and successive victories), making it premature and speculative. The petitioners (mostly non-residents) were also not the proper parties to raise this abstract issue.
• Method of Reapportionment: The Court upheld the method, following its ruling in Tobias v. Abalos. The Constitution provides that the House shall have a specific number of members "unless otherwise fixed by law." A special city charter is a "law" that can validly fix an increase in representation, preventing newly created cities from being denied legislative representation.
• Population Requirement: The argument was rejected. The Constitution (Article VI, Sec. 5(3)) provides that each city with a population of at least 250,000 shall have at least one representative. Makati's population of 450,000 exceeded this minimum, making the creation of a second district permissible.
• One Title-One Subject Rule: The Court found no violation. The title of the bill, which concerned converting Makati into a city, expressed the general subject. The creation of legislative districts is germane to the subject of creating a city, as representation is an essential attribute of a local government unit.

• Substantial Compliance with Territorial Requirements for LGU Creation: The requirement in the Local Government Code to describe a new LGU's territory by metes and bounds is a means to achieve the end of reasonably ascertaining its jurisdiction. When a bona fide boundary dispute exists, Congress may use a description based on existing, established boundaries without technical descriptions, provided the jurisdiction remains reasonably ascertainable.
• Justiciability / Actual Case or Controversy Requirement: Courts will not decide hypothetical, contingent, or abstract questions. A constitutional challenge must be premised on an existing, concrete dispute, not on a chain of speculative future events.
• Legislative Reapportionment via Special Law: Congress may validly increase the number of legislative districts for a specific locality through a special law (like a city charter), pursuant to its constitutional authority to fix the total number of House members "by law." This is distinct from the periodic general reapportionment required after a census.

• "The importance of drawing with precise strokes the territorial boundaries of a local unit of government cannot be overemphasized... Given the facts of the cases at bench, we cannot perceive how this evil can be brought about by the description made in section 2 of R.A. No. 7854... Congress maintained the existing boundaries of the proposed City of Makati but as an act of fairness, made them subject to the ultimate resolution by the courts."
• "The petition is premised on the occurrence of many contingent events... Considering that these contingencies may or may not happen, petitioners merely pose a hypothetical issue which has yet to ripen to an actual case or controversy."
• "To hold that reapportionment can only be made through a general apportionment law... would create an inequitable situation where a new city or province created by Congress will be denied legislative representation for an indeterminate period of time. The intolerable situations will deprive the people of a new city or province a particle of their sovereignty."

• Tobias v. Abalos, G.R. No. 114783, December 8, 1994 — Controlling precedent followed. The Court reiterated its ruling therein that reapportionment may be effected through a special law (a city charter) and that the "one title-one subject" rule should be liberally construed.
• Dumlao v. COMELEC, 95 SCRA 392 (1980) — Cited for the four requisites before a litigant may challenge the constitutionality of a law, particularly the requirement of an actual case or controversy.

• Section 10, Article X, 1987 Constitution — Provides that no LGU may be created, divided, or its boundary altered except in accordance with criteria established in the Local Government Code and subject to a plebiscite. The Court interpreted this in light of the pending boundary dispute.
• Sections 7 and 450, Local Government Code (R.A. No. 7160) — Require the territorial jurisdiction of a newly created city to be "properly identified by metes and bounds with technical descriptions." The Court held this was not an absolute, inflexible rule when a boundary dispute exists.
• Section 8, Article X & Section 7, Article VI, 1987 Constitution — Establish the three-year term limit for local officials and members of the House of Representatives. The Court found the challenge based on these provisions to be non-justiciable.
• Section 5(1) & (3), Article VI, 1987 Constitution — Provide that the House shall have not more than 250 members "unless otherwise fixed by law" and that each city with a population of at least 250,000 shall have at least one representative. The Court used these to uphold the creation of a second district for Makati.
• Section 26(1), Article VI, 1987 Constitution — The "one title-one subject" rule. The Court held it was not violated as the district creation was germane to the city conversion.

• Justice Hilario G. Davide, Jr. (Concurring) — While concurring in the result, Justice Davide offered additional reasoning. He emphasized that the metes-and-bounds requirement in the Local Government Code applied only to the conversion of a municipality into a component city, not a highly urbanized city like Makati. He also clarified that the increase in Makati's legislative district was permissible not under the "unless otherwise fixed by law" clause (which he argued pertains to general reapportionment), but under Section 3 of the Transitory Ordinance appended to the Constitution, which entitles a city whose population increases to over 250,000 to at least one representative.
