Ozaeta vs. Oil Industry Commission

The Court held that a petition for prohibition becomes moot and academic when supervening events eliminate the actual controversy between the parties. Because the Oil Industry Commission had already decided the main applications on the merits and expressly opted not to act on the provisional relief motions, the Court dismissed the petition without ruling on the Commission's statutory authority, emphasizing that judicial power extends only to actual cases and not to abstract or hypothetical disputes.

Between November 12 and 18, 1971, major oil companies filed applications with the Oil Industry Commission seeking the establishment of maximum selling prices for gasoline and other petroleum products. The companies concurrently filed motions for provisional relief requesting temporary price increases pending final determination of the main applications. The Commission issued a "Notice of Public Hearing" outlining proposed wholesale price adjustments and scheduling a preliminary hearing. Petitioners filed oppositions contesting the Commission's jurisdiction over the provisional motions, arguing that the Oil Industry Commission Act withheld such authority and that the Commission's procedural rules did not apply. The Commission denied the oppositions, asserted jurisdiction, and scheduled hearings, prompting the filing of the instant petition.

• Respondent oil companies filed separate applications with the Oil Industry Commission from November 12 to 18, 1971, docketed as OIC Cases Nos. 01-06, seeking the fixing of maximum selling prices for gasoline and other petroleum products.
• Concurrently, the oil companies filed separate motions for provisional relief requesting temporary price increases pending the final determination of their main applications.
• The Commission issued a "Notice of Public Hearing" outlining proposed wholesale price increases and setting a preliminary hearing for December 2, 1971.
• On December 1, 1971, petitioners filed oppositions to both the main applications and the motions for provisional relief, alleging that the Commission lacked statutory authority to grant provisional increases, that Section 2, Rule 13 of the Commission's Rules was inapplicable, and that the motions lacked merit.
• The Commission denied the oppositions via a December 20, 1971 Order, asserting jurisdiction over the motions and noting that interlocutory orders could be issued ex parte, though it opted to conduct a hearing.
• Petitioners filed a motion for reconsideration on December 28, 1971, reiterating that the Oil Industry Commission Act withholds authority for provisional price increases.
• The Commission denied the motion on January 7, 1972, citing Section 8(f) of Republic Act No. 6173 as conferring sufficient powers to perform acts necessary to discharge its functions.
• Petitioners filed the instant petition for prohibition on January 14, 1972, praying that the Commission be declared without jurisdiction to grant provisional price increases and that its December 20, 1971 and January 7, 1972 Orders be annulled.
• The Supreme Court issued a Restraining Order on January 21, 1972, enjoining the Commission from conducting a hearing or acting on the provisional relief motions, while expressly permitting proceedings on the main applications to continue.
• The Commission issued an Order on January 24, 1972, stating that it would not act ex parte on the provisional motions and would instead hear the basic applications on their merits.
• On September 18, 1972, the Commission rendered a Decision on the main applications, authorizing an across-the-board increase of not more than P0.02 per liter for locally refined petroleum products, subject to specified conditions.
• Respondents subsequently argued that the petition had become moot and academic due to the Commission's final disposition of the main applications and its explicit refusal to rule on the provisional relief motions.

• Petitioners maintained that the Oil Industry Commission Act (RA 6173) expressly withholds from the Commission the authority to grant provisional or temporary increases in the prices of petroleum products.
• Petitioners argued that Section 2, Rule 13 of the Rules of Practice and Procedure of the Oil Industry Commission was inapplicable to the pending motions for provisional relief.
• Petitioners contended that the motions lacked substantive merit and sought to prohibit the Commission from proceeding with hearings on provisional relief, while praying for the annulment of the Commission's December 20, 1971 and January 7, 1972 Orders asserting jurisdiction over the matter.

• Respondents countered that Section 8(f) of RA 6173 vested the Commission with sufficient powers to perform acts necessary or conducive to the exercise of its functions, including the granting of provisional relief.
• Respondents argued that the petition had become moot and academic because the Commission had already declined to act ex parte on the provisional motions, had proceeded to hear the main applications on their merits, and had rendered a final decision on said applications.
• Respondents asserted that no actual controversy remained between the parties, rendering judicial intervention unnecessary.

• Procedural Issues: Whether the petition for prohibition remains viable or has become moot and academic following the Oil Industry Commission's disposition of the main applications on the merits.
• Substantive Issues: Whether the Oil Industry Commission possesses statutory authority to grant provisional or temporary increases in the prices of petroleum products pending final adjudication of rate-setting applications.

• Procedural: The Court ruled that the petition must be dismissed for being moot and academic. The Court reasoned that the Commission had already resolved the main applications on the merits and had expressly decided not to act on the provisional relief motions. Because the action sought to be prohibited was no longer forthcoming, no actual controversy remained for judicial resolution.
• Substantive: N/A (The Court expressly declined to rule on the merits of the substantive issue, stating there was no necessity to determine the Commission's authority over provisional relief given the dismissal on procedural grounds.)

• Moot and Academic Doctrine — The doctrine provides that courts will not adjudicate cases that no longer present an actual, live controversy between the parties, as judicial power under the Constitution extends only to actual cases or controversies. The Court applied this doctrine by finding that the Commission's decision on the main applications and its explicit refusal to rule on the provisional motions eliminated the actual controversy. The Court found no overriding reason to address the hypothetical issue prospectively, thereby mandating dismissal.

• "We see no necessity in ruling on the merits of the petition and We reiterate the consistent holding of the Court that its duty is to decide actual controversies and not mere hypothetical cases." — This passage articulates the constitutional limitation on judicial power and directly supports the dismissal, emphasizing that the Court will not issue advisory opinions when supervening events have resolved the underlying dispute.

• In re Estate of Jose Ma. Ceballos — Cited as foundational precedent establishing the Court's duty to decide actual controversies and not mere hypothetical cases.
• Garron vs. Arca and Pineda — Followed to reinforce the requirement that a justiciable controversy must exist at the time of adjudication.
• Testate Estate of Jose Castillo y Refuerzo — Cited to affirm the established rule against adjudicating moot questions absent exceptional circumstances.
• Villacarlos vs. Jimenez — Referenced as supporting authority for dismissing petitions that have lost practical relevance due to supervening developments.

• Section 8(f), Republic Act No. 6173 (Oil Industry Commission Act) — Cited as the statutory basis for the Commission's asserted authority to perform acts necessary or conducive to its functions, though the Court did not rule on its substantive application due to the petition's mootness.
• Section 2, Rule 13 of the Rules of Practice and Procedure of the Oil Industry Commission — Referenced as the procedural rule allegedly inapplicable to motions for provisional relief, forming part of the underlying dispute that was left unresolved.

• Justice Aquino — Concurred in the result, aligning with the dismissal of the petition as moot and academic without articulating separate legal reasoning.
