The Supreme Court sided with consumers, ruling that MERALCO, the Philippines’ largest electricity distributor, cannot include its income tax payments as part of its operating expenses when calculating rates. This decision prevents MERALCO from passing its income tax burden onto consumers, ensuring fairer electricity pricing. The Court emphasized that public interest should prevail over private profits in the regulation of public utilities.

Power Play: When Should Meralco Shoulder Taxes, Not Consumers?

In 1993, MERALCO sought to increase its rates by an average of 21 centavos per kilowatt-hour (kWh). The Energy Regulatory Board (ERB) provisionally approved an increase of P0.184 per kWh, but with a condition: if an audit showed MERALCO deserved less, the excess would be refunded or credited to customers. The Commission on Audit (COA) then recommended that MERALCO’s income taxes shouldn’t be part of operating expenses for rate calculations. Subsequently, the ERB agreed and authorized MERALCO to implement a rate adjustment of P0.017 per kWh, effectively ordering a refund of the excess amount collected.

MERALCO appealed, and the Court of Appeals reversed the ERB’s decision, allowing MERALCO to include income tax as part of its operating expenses. This prompted the Republic and Lawyers Against Monopoly and Poverty (LAMP) to bring the case to the Supreme Court. The central legal question revolved around whether MERALCO could pass its income tax burden onto consumers and the proper method for valuing MERALCO’s assets for rate determination.

The Supreme Court emphasized that regulating public utility rates falls under the State’s police power, designed to protect the public interest. Rates should balance the utility’s need for a reasonable return on investment with the consumer’s right to fair pricing. The Court quoted Justice Brandeis’ dissenting opinion in Southwestern Bell Tel. Co. v. Public Service Commission, highlighting that utilities act as public servants and their charges must be reasonable. The Supreme Court held that while rate-fixing is a legislative function, the fairness and reasonableness of those rates are subject to judicial review.

The ERB, tasked with regulating energy distribution and setting rates, must ensure these rates are “reasonable and just.” This standard, the Court noted, requires discretion, good judgment, and independence. It means rates can’t be so low as to be confiscatory for the utility, or so high as to be oppressive for consumers. Furthermore, the court acknowledged its deference to the factual findings of administrative bodies like the ERB, especially on technical matters, as long as those findings are supported by substantial evidence. This principle acknowledges the expertise of regulatory bodies in their specific fields.

In determining just and reasonable rates, the Court identified three critical factors: the rate of return, the rate base, and the return itself (the computed revenue). The rate of return, a percentage multiplied by the rate base, determines a fair profit for the utility. The rate base is the value of the property the utility uses to provide its service. The crux of this case was determining which operating expenses should be allowed and how to properly value the rate base.

The Court firmly sided with the ERB’s ruling that income tax should not be included as an operating expense. Operating expenses are those directly related to generating revenue. Income tax, however, is a tax on the privilege of earning income, a payment to the State for protection and services. The Court reasoned that income tax payments don’t directly contribute to the utility’s operations or benefit its customers; therefore, the burden of paying income tax should rest solely on MERALCO. Allowing MERALCO to pass this cost onto consumers would be unjust and inequitable.

MERALCO cited American case law to support its argument. The Supreme Court rejected this, stating that rate determination depends on the specific environment and factors. These include the utility’s financial condition, service quality, competition, risk, and consumer capacity. What constitutes a reasonable return must consider these unique conditions. The Court also expressed concern that allowing income tax to be treated as an operating expense could set a dangerous precedent, turning public utilities into “tax collectors” rather than taxpayers.

Addressing the valuation of MERALCO’s assets, the Supreme Court supported the ERB’s use of the “net average investment method.” This method values assets based on the actual number of months they were in service during the test year. MERALCO argued for the “average investment method,” which averages the value of assets at the beginning and end of the year. The Court found the net average investment method more accurate, reflecting the actual use of the property.

The COA’s report supported the ERB, confirming that MERALCO recorded properties in its books as they were placed in service. This undermined MERALCO’s argument that recording delays justified the trending method. The Court reasoned that using the net average investment method prevents manipulation of the rate base. Otherwise, a utility could include highly capitalized assets used for only a short period, unfairly inflating its rate base.

MERALCO further contended that the ERB violated the rule of stare decisis by not following previous decisions that allegedly upheld the “trending method”. The Supreme Court dismissed this argument, reiterating that no immutable method exists for rate-making. No utility has a vested right to a particular valuation method. The Court emphasized that MERALCO had failed to demonstrate that the ERB-prescribed rates were unjust or confiscatory. A legal presumption exists that rates set by administrative agencies are reasonable. It is the burden of the party challenging the rates to prove otherwise, which MERALCO failed to do.
