G.R. No. 14019 - Ayson vs. Provincial Board of Rizal

Plaintiffs/Appellants: Jose Ayson and Pedro Ignacio.
Defendants/Appellees: The Provincial Board of Rizal and the Municipal Council of Navotas.
The case arose from a petition challenging the validity of a municipal ordinance affecting the fishing industry, and subsequently, the constitutionality of a provision in the Administrative Code.

On September 17, 1916, the Municipal Council of Navotas, Rizal, adopted Ordinance No. 13.
Section 2 of the ordinance required:

All owners and proprietors engaged in the fishing industry using nets known as “cuakit” and “pantukos” to secure a license before fishing in the bay within three leagues of the municipality’s shore-line.
Submission of a license, issued by the municipal government, after payment of a fee of ₱50 annually, payable every three months.

At the time the ordinance was enacted, Section 2270 of the Administrative Code of 1916 was in force.
The section stated that if a municipal council had not granted the exclusive privilege of fishery in municipal waters, it could impose a license tax upon the privilege of taking fish using nets, traps, or other fishing tackle; however, such a license did not confer an exclusive right to fishery.
The legal question centered on whether this statutory grant of authority was valid.

Plaintiffs contended that the authority for regulating the use of public waters had already been provided by:

They argued that the Legislature was precluded from abrogating these preexisting provisions through the enactment of Section 2270.
Plaintiffs further argued that the Administrative Code was unconstitutional because it embraced more than one subject, thereby violating the rule that a bill should not combine multiple subjects.

At the time the Administrative Code of 1916 was enacted, the control of the Philippine Bill and its provisions (e.g., paragraph 17, section 5) applied only to private or local bills, not a general codification such as the Administrative Code.
When the Administrative Code of 1917 was enacted, it was subject to paragraph 17, section 3 of the Act of Congress of August 29, 1916, which similarly required bills to embrace only one subject—a provision that did not adversely affect the general revision of statutes.
The appellants highlighted the potential conflict between the requirement for single subject bills and the nature of the Administrative Code, but this argument was met with counterargument regarding the nature of codification.

Whether Section 2270 of the Administrative Code of 1916 (now Section 2324 of the Administrative Code of 1917) is constitutionally valid as a basis for the municipal ordinance imposing a license tax on fishing activities.

Whether legislative provisions already regulating the use of public waters (via the Civil Code and Spanish Law of Waters) restrict or invalidate a legislative amendment that imposes additional regulatory measures through the Administrative Code.

Whether the inclusion of multiple subjects in the Administrative Code (given its title and form) violates the constitutional requirement that a bill shall embrace only one subject.
