In a four-page resolution, the Court of Appeals dismissed the petition of Enrile and the other petitioners because of a technicality. The appellate court ruled that the petitioners failed to comply with its resolution dated July 20, mandating both parties to file their manifestation if there are supervening events that would render the case moot and academic.
The court also pointed out that Enrile and the other petitioners have shown lack of interest in the case in line with provisions in the Rules of Court. The decision was penned by Associate Justice Ramon Garcia.
Other appellate justices who concurred in the ruling are magistrates Josefina Guevara-Salonga and Vicente Roxas.
In its July 20 resolution, the Court of Appeals warned that the petitioners' failure to file their manifestation would be ground for the case's dismissal.
Enrile, Bacani, Linda Montayre, Herman Tiu Laurel and several other personalities filed their petition for certiorari with prayer for a temporary restraining order and/or writ of preliminary injunction on June 11, 2002, before Pasig Regional Trial Court Judge Alfredo Flores assailing the constitutionality of section 34 of Republic Act 9136, or the "Electric Power Industry Reform Act (EPIRA) Law."
The petitioners wished to enjoin Napocor and Meralco from imposing and collecting the power purchase adjustment and power purchase cost adjustment.
Judge Flores junked the petition on June 21, 2002, and the subsequent motion for reconsideration on October 3, 2002. The petitioners elevated the case with the Court of Appeals, which was assigned to then-Presiding Justice Ruben Reyes. The case was unloaded by Reyes when he was promoted to the Supreme Court. It was later raffled off to Justice Garcia.
In the Court of Appeals, Napocor asked for the dismissal of the case since supervening events had set in since "the subject PPA and PPCA charges are no longer included in the rate structures being charged by respondent Napocor to its customers, including respondent Meralco."
Napocor also argued that "there is in place a generation rate adjustment mechanism (GRAM) and incremental currency exchange rate adjustment (ICERA), which replaced PPCA and FOREX bundled rates. The implementation of these cost adjustments (is) subject t regulatory process, such as public hearings, before their approval by the (ERB)."
Meralco also prayed for the junking of the case since the power costs are now computed based on the guidelines for the automatic adjustment of generations rates and system loss rates of distribution utilities (AGRA) adopted by the Energy Regulatory Commission.
Adjusting the power rates is part of Meralco's mandate, while the validity of the power purchase adjustment as a special power rate has been upheld by the Supreme Court since 1986.
