G.R. No. L-26906 - De Leon vs. Municipality of Calumpit

Plaintiffs: Sancho B. De Leon and Venancio F. Lim, holders of municipal franchises to operate electric plants.
Defendants: The Municipalities of Calumpit and Hagonoy, Bulacan.
The disputes arise from the imposition of municipal license taxes and fees on the operation of electric plants under franchise.

In Calumpit, on April 18, 1962, an ordinance imposed a municipal license tax of P700.00 plus a mayor’s permit fee of P25 on operators of electric plants.
In Hagonoy, on January 19, 1962, an ordinance imposed an annual municipal license tax of P1,200.00 on persons, associations, and corporations engaged in operating electric light, heat, and power plants.
Both municipalities defended the ordinances by invoking provisions of the Local Autonomy Act.

The Local Autonomy Act contained express language that generally negated the municipal power to tax persons operating waterworks, irrigation, and other public utilities.
An exception was provided whereby utilities engaged in the operation of electric light, heat, and power plants were not expressly exempted from local taxation.
A rule of construction in the Act mandated a liberal interpretation in favor of the municipal power unless conclusively prevented by clear statutory provisions.

The complaints challenging the imposition of municipal license taxes were filed before the Court of First Instance of Bulacan.
On November 4, 1964, the lower court, presided over by Judge Samuel F. Reyes, dismissed the complaints sustaining the municipal ordinances based on the Local Autonomy Act’s provisions.
The lower court’s decision was rendered in a context where there was ongoing development in the jurisprudence regarding municipal taxing powers over electric plant operators.

Subsequent decisions in 1966—Butuan Sawmill, Inc. v. City of Butuan and Ilocos Norte Electric Co., Inc. v. Municipality of Laoag—addressed the issue of municipal power to tax electric light and power utilities.
These decisions clarified that local governments cannot impose additional municipal license taxes on electric power companies that are already subject to franchise tax unless explicitly provided for in the franchise.
The controlling jurisprudence influenced the appellate review of the lower court’s decisions in the present cases.

The Supreme Court reviewed both appeals together, noting the similarity of the issues in the Calumpit and Hagonoy cases.
Plaintiffs argued that as holders of municipal franchises, they were exempt from the imposition of the aforementioned municipal license taxes.
The Supreme Court agreed with the controlling jurisprudence and held that the municipalities lacked the power to levy such taxes on franchise holders.

Whether a municipal license tax may be validly imposed by ordinance on a holder of a franchise to operate an electric plant.
Whether the municipal taxing power under the Local Autonomy Act extends to entities already subject to franchise taxation.

How to read the conflicting provisions of the Local Autonomy Act in light of later statutory interpretation, particularly with regard to electric power companies that are franchisees.
Whether the exception for operating waterworks, irrigation, and other public utilities implicitly excludes electric plant operators from municipal taxation unless otherwise authorized.

The extent to which the decisions in Butuan Sawmill, Inc. and Ilocos Norte Electric Co., Inc. override the municipal ordinances enacted by Calumpit and Hagonoy.
Whether the franchise held by the plaintiffs exempts them from local taxation based on the legislative and judicial precedents.
