Cityhood Laws and the Constitutional Criteria for Creating Philippine Cities

The Supreme Court's 2010 ruling in League of Cities of the Philippines v. COMELEC (G.R. No. 176951) reaffirmed a fundamental constitutional principle: Congress cannot create cities by exempting municipalities from the criteria written in the Local Government Code. The decision, which reinstated an earlier 2008 ruling, struck down 16 separate cityhood laws for violating Section 10, Article X of the 1987 Constitution and the equal protection clause. This case matters because it defines the limits of legislative power over local government units and protects the uniformity of standards for city creation.

The Facts of the Case

In 2001, Congress enacted Republic Act No. 9009, which amended the Local Government Code by raising the income requirement for converting a municipality into a city from ₱20 million to ₱100 million. The law aimed to curb the "mad rush" of municipalities seeking cityhood.

Despite this increased requirement, Congress later passed 16 separate cityhood laws that exempted specific municipalities from the ₱100 million income threshold. These laws allowed municipalities like Baybay, Bogo, Catbalogan, Tandag, Borongan, Tayabas, Lamitan, Tabuk, and others to become cities despite failing to meet the new requirement. The specific Republic Act numbers of these cityhood laws are identified in the Supreme Court decision.

The League of Cities of the Philippines and several existing cities challenged these laws, arguing that they violated the Constitution and unfairly reduced the internal revenue allotment shares of established cities.

The Constitutional Issue

Section 10, Article X of the 1987 Constitution provides that no city shall be created except in accordance with the criteria established in the local government code. The Court interpreted this provision strictly: all criteria for creating cities must be found exclusively in the Local Government Code, not in any other law.

The Court reasoned that the Constitution's clear intent is to ensure that the creation of cities follows uniform, non-discriminatory criteria found solely in the Local Government Code. When Congress enacted the cityhood laws with exemptions from the income requirement, it wrote criteria into laws other than the Code—a direct violation of the constitutional mandate.

The Equal Protection Analysis

The Court also found the cityhood laws violative of the equal protection clause. The classification used—mere pendency of a cityhood bill in the 11th Congress—did not rest on a substantial distinction. As the Court noted, the pendency of a bill does not affect or determine the level of income of a municipality. Municipalities with pending bills might even have lower incomes than those without.

The classification also failed because it was limited to existing conditions only. The specific circumstance of having a pending bill before the end of the 11th Congress could never happen again, violating the requirement that valid classifications apply to all similarly situated parties. Municipalities with the same income as the 16 respondents could not convert into cities, while the respondents could.

The Operative Fact Doctrine

The Court clarified that the operative fact doctrine—which recognizes the effects of an unconstitutional law before its nullification—does not validate an unconstitutional law. While acts done in reliance on the cityhood laws, such as payment of salaries or issuance of licenses, may be recognized for equity and fair play, the laws themselves remain void.

The Court warned against the dangerous precedent of allowing unconstitutional laws to become permanent simply because they were implemented before being struck down. Such a view, the Court said, would open the floodgates to the wanton enactment of unconstitutional laws.

Practical Takeaways

• Congress cannot bypass the Local Government Code. Any criteria for creating cities, including exemptions from income requirements, must be written into the Code itself—not into special laws.
• The ₱100 million income requirement is the current standard. Municipalities seeking cityhood must satisfy the income requirement set by the Local Government Code, as amended by RA 9009, unless the Code itself is amended.
• Classifications must rest on substantial distinctions. A classification based on the mere pendency of a bill—an arbitrary date—cannot survive equal protection scrutiny.
• The operative fact doctrine has limits. It protects innocent parties who relied on an unconstitutional law, but it never makes the law constitutional.
• Legislative power is not unlimited. While Congress can amend the Local Government Code, it cannot achieve the same result indirectly through piecemeal exemptions in separate laws.
