Case Summary (G.R. No. 254440)
Factual Background
The EPIRA established the Wholesale Electricity Spot Market (WESM) and provided for a Market Operator initially constituted as an Autonomous Group Market Operator (AGMO) and later to be succeeded by an Independent Market Operator (IMO) jointly endorsed by the Department of Energy (DOE) and electric power industry participants pursuant to Section 30. The Philippine Electricity Market Corporation (PEMC) initially served as AGMO and, pursuant to DOE initiative, the DOE issued D.C. No. DC2018-01-0002 adopting policies for the transition to an IMO. The PEMC board approved an IMO Transition Plan and the members ratified it. Thereafter, Independent Electricity Market Operator of the Philippines, Inc. (IEMOP) was organized as a non-stock, non-profit private corporation to act as the IMO. PEMC and IEMOP executed an Operating Agreement in September 2018 transferring market operator functions, personnel, assets, and liabilities from PEMC to IEMOP, and IEMOP assumed those functions on 26 September 2018. WESM commercial operations began in stages in 2006, 2010, and 2017 in Luzon, Visayas, and Mindanao respectively.
Petition and Administrative Interaction
On 18 August 2020, IEMOP filed before the ERC the Market Fees Application for Calendar Year 2021 together with the documents required under the ERC Rules' pre-filing requirements. The ERC acknowledged receipt and referred the Application for technical pre-filing. On 01 September 2020, an ERC Market Operations Service officer sent an e-mail returning the Application “as directed by superiors,” advising that PEMC should be the applicant and attaching a pre-filing checklist. IEMOP submitted additional documents on 28 September 2020 and 12 October 2020 and sought certification of completion of technical pre-filing. After repeated follow-ups by IEMOP in December 2020 and January 2021 with no substantive response, IEMOP filed the present Petition for Mandamus on 11 December 2020 to compel the ERC to act on its Market Fees Application. The ERC, through the Office of the Solicitor General, answered that it had acted by returning the Application for lack of certain documentary requirements and that PEMC remained the proper applicant because it continued to exist as AGMO. IEMOP replied and later supplemented the petition with communications showing that the DOE Secretary and PEMC itself had confirmed IEMOP’s assumption as the IMO and its entitlement to file for market fees.
Parties’ Contentions
IEMOP contended that it was the duly constituted IMO and therefore had the statutory right and obligation to file the Market Fees Application with the ERC for approval, that it complied with the ERC pre-filing requirements, and that the ERC unlawfully neglected its duty by refusing to verify completeness and to act on the Application. IEMOP sought only an order compelling the ERC to proceed with dispatch and to act on the Application, not a directive on the merits. The ERC contended that it had acted when it returned or rejected the Application by e-mail for lack of documentary requirements and that PEMC remained the Market Operator and the proper party to file the application. The ERC further argued that mandamus was improper because the approval of market fees involved the exercise of discretion rather than a purely ministerial act.
Issue Presented
Whether a writ of mandamus was a proper remedy to compel the ERC to act upon the Market Fees Application for Calendar Year 2021 filed by IEMOP.
Ruling
The petition was granted. The Court exercised jurisdiction under Section 78 of the EPIRA, which confines the Court’s jurisdiction to matters involving implementation of EPIRA provisions. The Court found the requisites for mandamus satisfied and ordered the ERC to immediately act upon and resolve IEMOP’s Market Fees Application.
Legal Reasoning — Right to File and Compliance with Pre‑filing Requirements
The Court held that IEMOP had a clear legal right to file the Market Fees Application because Section 30 of the EPIRA, the EPIRA IRR, the WESM Rules, the DOE Department Circular, the IMO Transition Plan, and the Operating Agreement assigned the Market Operator role to the IMO after transition and vested in the Market Operator the right and obligation to recover WESM administration costs through market fees subject to ERC approval. The Operating Agreement expressly made IEMOP responsible for filing the application. The Court found documentary proof that IEMOP complied with Rule 6 of the ERC Rules' pre-filing requirements, including proof of service on the Pasig City legislative body, an affidavit of publication, and supplementary documents submitted within the time allowed under ERC guidelines following the ERC’s 01 September 2020 e-mail. Consequently, the Court concluded that there was no factual basis for the ERC’s rejection of the Application on the ground of lacking documentary requirements.
Legal Reasoning — Duty of ERC, Unlawful Neglect, and Inaction
The Court emphasized that the ERC, while an independent quasi‑judicial regulatory body under Section 38 of EPIRA, was duty‑bound to enforce and apply the rules, regulations, and circulars issued by the DOE pursuant to EPIRA, and lacked authority to disregard or amend those DOE issuances. The ERC had three duties imposed by law and its own rules and guidelines: to implement the DOE‑endorsed transition to the IMO; to act on market‑fee applications filed by the Market Operator; and to verify the completeness of pre‑filing requirements and notify the pre‑filer with either a Confirmation of Completeness E‑mail or a Notice of Incomplete Submission E‑mail. The Court found that the ERC unlawfully neglected those duties by refusing to recognize IEMOP as the Market Operator, by failing to issue either a CCE or a proper NISE after IEMOP’s compliant submissions, and by communicating to PEMC rather than properly notifying IEMOP. The Court held that the 01 September 2020 e-mail could not be treated as an official denia
