Republic vs. Pilipinas Shell Petroleum Corporation

Administrative rules and regulations intended to enforce or implement existing law must be published in the Official Gazette or a newspaper of general circulation and filed with the Office of the National Administrative Register (ONAR) to be effective; non-compliance renders them ineffective and incapable of being the basis of any sanction, regardless of actual knowledge by the regulated party or subsequent legislative affirmations of the rule-making authority.

The Oil Price Stabilization Fund (OPSF) was created under Presidential Decree No. 1956 to minimize frequent oil price changes caused by exchange rate adjustments and world market price increases. To implement the OPSF, Ministry of Finance (MOF) Circular No. 1-85 was issued, imposing a surcharge for late remittance of foreign exchange risk charges. The Department of Energy (DOE) demanded that Pilipinas Shell Petroleum Corporation pay surcharges for underpayments covering the period December 1989 to October 1991. Shell paid the principal underpayment but refused to pay the surcharges, challenging the validity of the circular imposing them.

• OPSF Creation: Presidential Decree No. 1956 created the OPSF, supplemented by Letter of Instructions Nos. 1431 and 1441, and later amended by Executive Order No. 137 to expand its sources and utilization.
• Imposition of Surcharges: MOF Circular No. 1-85, as amended by Department of Finance Circular No. 2-94, prescribed a 15% surcharge for late payment of OPSF remittances, plus 2% per month if paid after 30 days.
• Demand for Payment: In December 1991, the OEA informed Shell of underpayments for December 1989 to March 1991, imposing surcharges. A subsequent letter in December 1991 demanded payment for underpayments from April to October 1991, with additional surcharges.
• Partial Payment: Shell paid the principal underpayment of P24,554,387.31 in March 1992 but refused to pay the surcharges, maintaining that its calculations were based on a valid interpretation of MOF Order No. 11-85 and MOE Circular No. 85-05-82.
• Administrative Appeal: In March and July 1996, the OEA and DOE reiterated the demand for surcharges and threatened to draw on Shell's Irrevocable Standby Letter of Credit. Shell appealed to the Office of the President.

• Legislative Vitality: Petitioner argued that MOF Circular No. 1-85 was affirmed by Executive Order No. 137, receiving vitality from a legislative enactment, thus obviating the need for registration with the ONAR.
• Waiver: Petitioner maintained that respondent waived its objection based on non-registration when it paid the principal amount of underpayment.
• Actual Knowledge: Petitioner insisted that registration was unnecessary because respondent knew of the circular's existence despite its non-registration.

• Ineffectivity for Non-Compliance: Respondent countered that MOF Circular No. 1-85, as amended, is ineffective for failure to comply with the mandatory requirements of publication and filing with the ONAR under the Administrative Code of 1987.
• No Waiver: Respondent argued that payment of the principal underpayment did not constitute a waiver of the right to question the surcharges, as the underpayment was based on a different issuance (MOF Order No. 11-85) than the surcharges (MOF Circular No. 1-85).

• Effectivity of Administrative Issuances: Whether MOF Circular No. 1-85, as amended, is ineffective for failure to comply with the publication and filing requirements under the Administrative Code of 1987, notwithstanding its alleged affirmation by Executive Order No. 137.
• Waiver: Whether respondent waived its objection to the imposition of surcharges based on non-registration when it paid the principal amount of underpayment.

• Effectivity of Administrative Issuances: MOF Circular No. 1-85, as amended, was declared ineffective for non-compliance with the mandatory requirements of publication and filing. Under the doctrine in Tañada v. Tuvera and Section 3, Chapter 2, Book VII of the Administrative Code of 1987, administrative rules intended to enforce existing law must be published and filed with the ONAR. Certifications from the ONAR confirmed the circulars were not filed, and petitioner failed to prove publication. The subsequent enactment of Executive Order No. 137, which reiterated the rule-making power of the Minister of Finance, did not exempt the circular from these due process requirements.
• Waiver: No waiver occurred. The payment of the principal underpayment was based on MOF Order No. 11-85, which is distinct from MOF Circular No. 1-85 that imposed the surcharges. Furthermore, strict compliance with publication requirements cannot be annulled by mere allegation of actual knowledge or notification of the circular's existence.

• Doctrine of Publication — Publication in the Official Gazette or a newspaper of general circulation is indispensable for statutes and administrative rules intended to enforce or implement existing law to attain binding force and effect. The Court applied this to invalidate MOF Circular No. 1-85, which lacked proof of publication.
• Filing Requirement under the Administrative Code of 1987 — Administrative rules in force on the date of the effectivity of the Administrative Code of 1987 must be filed with the ONAR within three months; otherwise, they cannot thereafter be the basis of any sanction against any party or persons. The Court applied this to invalidate the circular based on ONAR certifications confirming non-filing.

• "Administrative rules and regulations must also be published if their purpose is to enforce or implement existing law pursuant also to a valid delegation." — Reaffirming the mandatory nature of publication for administrative issuances.
• "Strict compliance with the requirements of publication cannot be annulled by a mere allegation that parties were notified of the existence of the implementing rules concerned." — Emphasizing that actual knowledge is not a substitute for compliance with publication and filing requirements.

• Tañada v. Tuvera, G.R. No. L-63915, 29 December 1986, 146 SCRA 446 — Controlling precedent establishing the mandatory requirement of publication for administrative rules and regulations intended to enforce existing law.
• National Association of Electricity Consumers for Reforms v. Energy Regulatory Board, G.R. No. 163935, 2 February 2006, 481 SCRA 480 — Followed; emphasized that both publication and filing are mandatory for effectivity of administrative issuances and that public consultation or actual knowledge does not substitute for publication.
• Republic v. Express Telecommunications Co., Inc. — Cited; held that publication is a condition sine qua non before statutes, rules, or regulations can take effect, even if filed with the ONAR.

• Section 3, Chapter 2, Book VII, Administrative Code of 1987 — Requires agencies to file certified copies of every rule adopted with the UP Law Center (ONAR) and mandates that rules in force upon the Code's effectivity must be filed within three months, or else they cannot be the basis of any sanction. Applied to invalidate MOF Circular No. 1-85 for non-filing.
• Presidential Decree No. 1956 — Created the Oil Price Stabilization Fund (OPSF). MOF Circular No. 1-85 was intended to implement this decree.
• Executive Order No. 137 — Amended PD 1956, expanding the sources and utilization of the OPSF. Did not exempt MOF Circular No. 1-85 from publication and filing requirements.
• MOF Circular No. 1-85 (as amended by DOF Circular No. 2-94) — Imposed a 15% surcharge for late payment of OPSF remittances. Declared ineffective for non-compliance with publication and filing requirements.
