Facts

• On April 1, 1990 the DENR's Environmental Management Bureau issued an Environmental Compliance Certificate (ECC) to Marcopper Mining Corporation, expressly conditioned on containment of run-off and silt from reaching the Mogpog and Boac River systems.
• On March 24, 1996 mine tailings gushed out at the base of the Mt. Tapian drainage tunnel, where Marcopper had placed a concrete plug, discharging millions of tons of pollutants into the Boac and Makalupnit rivers in Marinduque.
• In August 1996 the DOJ filed twelve separate Informations in the MTC of Boac against John Eric Loney (President/CEO), Steven Paul Reid (Senior Manager) and Pedro B. Hernandez (Resident Manager), on four distinct charges — violation of P.D. No. 1067 (Water Code, dumping without permission), P.D. No. 984 (National Pollution Control Decree, actual pollution), R.A. No. 7942 (Philippine Mining Act, gross neglect of the ECC terms), and Article 365§ (reckless imprudence resulting in damage to property). Twelve sheets, each charging one offence — the fact that decides the duplicity question.
• Petitioners moved to quash on duplicity of charges, on the claim that two of them were not yet officers, and on alleged legal excuses in the Informations.
• On April 28, 1997 the MTC partially granted the motion, quashing the P.D. No. 1067 and P.D. No. 984 charges as "absorbed" by the Mining Act, while keeping R.A. No. 7942 and Article 365§.
• On May 28, 1997 petitioners were arraigned on the surviving charges and, refusing to plead to the Mining Act count, had "not guilty" entered for them.
• On March 20, 1998 the RTC, Branch 94 set aside the quashal and reinstated the two decrees.
• On November 5, 2001 the Court of Appeals affirmed in toto, holding duplicity unavailable where separate offences are charged in separate Informations; reconsideration denied March 14, 2002. Decided February 10, 2006 (Third Division).

Issue

Ruling

"WHEREFORE, we DENY the petition. We AFFIRM the Decision dated 5 November 2001 and the Resolution dated 14 March 2002 of the Court of Appeals.

SO ORDERED."

Ratio

• The Court read Section 13 literally. It prohibits charging more than one offence "in a single complaint or information": "Duplicity of offense. — A complaint or information must charge but one offense, except only in those cases in which existing laws prescribe a single punishment for various offenses." Its rationale is "to avoid confusing the accused" and let him prepare a defence — and with twelve Informations each charging one offence, the ground was "structurally and procedurally untenable."
• The multiple-prosecution question is answered by the additional-element test (People v. Doriquez): "where two different laws … define two crimes, prior jeopardy as to one of them is no obstacle to a prosecution of the other, although both offenses arise from the same facts, if each crime involves some important act which is not an essential element of the other."
• The Court then walked the four statutes and named the distinguishing element of each. P.D. No. 1067 — dumping without a prior permit; "[o]ne can be prosecuted … even in the absence of actual pollution." P.D. No. 984 — actual pollution; without it there is no liability … even if there was unauthorized dumping. R.A. No. 7942 — willful violation and gross neglect of the ECC terms. Article 365§ — lack of necessary or adequate precaution, a malum in se requiring criminal negligence.
• Relova is distinguished on the constitutional text itself. There the prosecutions were under a municipal ordinance and then a national statute, engaging the second sentence of Section 21, Article III: "If an act is punished by a law and an ordinance, conviction or acquittal under either shall constitute a bar to another prosecution for the same act." Here all four are national statutes, so the first sentence governs — which bars only a second prosecution for the "same offense," and these are not the same.
• Absorption fails on the mala in se / mala prohibita divide: RPC felonies require intent or negligence, special-law offences require only "the mere commission of the prohibited act," and [a] mala in se felony cannot absorb mala prohibita crimes.

Doctrine

• It "exists only when a single complaint or information charges more than one offense," and cannot be pleaded as a ground for quashal when the prosecution files separate sheets of Information for each offence.
• The distinct-offences doctrine: a single act may offend two or more entirely distinct provisions, and where each "requires proof of an additional fact or element which the others do not," prosecution under all is proper and raises no double jeopardy.
• The two sentences of Section 21, Article III do different work: the first bars a second prosecution for the "same offense," permitting multiple national prosecutions for one act where the offences are distinct; the second bars a second prosecution for the "same act" where one law is a local ordinance and the other a national statute.
• No absorption across the mala in se / mala prohibita line.

• The ordinance–statute bar is absolute where it applies. Under the second sentence, if a single act is penalised by both a national law and an ordinance, conviction or acquittal under either bars the other — regardless of whether the technical elements of the offenses are different. That is why Relova went the other way, and it is the one situation in which the additional-element test does not save the second prosecution.
• The holding is procedural, not substantive: nothing was decided about guilt, about whether the officers held their posts at the time, or about the alleged legal excuses — only that the Informations survive a motion to quash.
• And note the practical shape of the rule: the State's protection against a duplicity attack is simply to file separately, which is what makes Section 13 a rule about drafting rather than about how many charges one act may bear.

Facts

• April 1, 1990: The Environmental Management Bureau of the Department of Environment and Natural Resources (DENR) issues an Environmental Compliance Certificate (ECC) to Marcopper Mining Corporation, with the explicit condition that Marcopper must ensure the containment of run-off and silt materials from reaching the Mogpog and Boac River systems.
• March 24, 1996 (also alleged in some records as March 24, 1994): Mine tailings gush out of or near the base of the Mt. Tapian drainage tunnel, where Marcopper had placed a concrete plug, discharging millions of tons of pollutants into the Boac and Makalupnit rivers in Marinduque.
• August 1996: The Department of Justice (DOJ) files separate criminal Informations in the Municipal Trial Court (MTC) of Boac, Marinduque, separately charging petitioners John Eric Loney (President/CEO), Steven Paul Reid (Senior Manager), and Pedro B. Hernandez (Resident Manager for Mining Operations) with four distinct offenses across twelve separate sheets:
  1. Criminal Case Nos. 96-44, 96-45, and 96-46: Violation of Article 91(B), sub-paragraphs 5 and 6 of P.D. No. 1067 (Water Code of the Philippines) for dumping mine tailings without permission.
  2. Criminal Case Nos. 96-47, 96-48, and 96-49: Violation of Section 8 of P.D. No. 984 (National Pollution Control Decree of 1976) for causing actual pollution.
  3. Criminal Case Nos. 96-50, 96-51, and 96-52: Violation of Section 108 of R.A. No. 7942 (Philippine Mining Act of 1995) for gross neglect to abide by the terms of the ECC.
  4. Criminal Case Nos. 96-53, 96-54, and 96-55: Violation of Article 365§ of the Revised Penal Code (RPC) for Reckless Imprudence Resulting in Damage to Property.
• Subsequent Date (Exact Date NOT IN RECORD): Petitioners file a Motion to Quash the Informations on three grounds: (a) duplicity of charges; (b) Loney and Reid were not yet officers of Marcopper when the incident occurred; and (c) the Informations contain legal excuses or justifications.
• January 16, 1997: The MTC of Boac, Marinduque (Judge Celso De Jesus Zoleta) issues a Joint Order deferring its ruling on the motion for lack of "indubitable ground for the quashing of the informations."
• April 28, 1997: Upon petitioners' motion for reconsideration, the MTC issues a Consolidated Order partially granting the motion and quashing the charges under P.D. No. 1067 and P.D. No. 984 on the ground of "absorption" by the Philippine Mining Act (R.A. No. 7942). However, the MTC maintains the charges under R.A. No. 7942 and Article 365§ of the RPC.
• May 28, 1997: Petitioners are arraigned on the charges for violation of R.A. No. 7942 and Article 365§ of the RPC. Upon their refusal to plead to the Mining Act, the MTC orders the entry of "not guilty" pleas for both offenses.
• Subsequent Date (Exact Date NOT IN RECORD): Petitioners file a petition for certiorari with the Regional Trial Court (RTC) of Boac, Marinduque (Branch 94) assailing the maintenance of the Mining Act charges. Concurrently, the People of the Philippines file an ordinary appeal with Branch 38 challenging the quashal of the Water Code and Anti-Pollution Law charges. The cases are subsequently consolidated before Branch 94.
• March 20, 1998: The RTC of Boac, Marinduque, Branch 94 (Judge Rodolfo B. Dimaano), issues a Resolution granting the People's appeal, setting aside the quashal of P.D. No. 1067 and P.D. No. 984, ordering their reinstatement, and denying petitioners' petition.
• Subsequent Date (Exact Date NOT IN RECORD): Petitioners file a petition for certiorari under Rule 65 with the Court of Appeals (CA) assailing the RTC's Resolution.
• November 5, 2001: The CA (Special Thirteenth Division) renders a Decision affirming in toto the RTC Branch 94 Resolution, holding that duplicity is not a valid ground for quashal when separate offenses are charged in separate Informations, and that the offenses are distinct.
• March 14, 2002: The CA issues a Resolution denying petitioners' motion for reconsideration.
• Subsequent Date (Exact Date NOT IN RECORD): Petitioners file the instant Petition for Review on Certiorari under Rule 45 before the Supreme Court.
• February 10, 2006: The Supreme Court Third Division promulgates its Decision denying the petition and affirming the Court of Appeals.

Arguments of the Parties

• Substantial Insufficiency via Duplicity of Charges: The petitioners argued that charging them with four different offenses for a single act or incident of dumping mine tailings constitutes "duplicity of charges" which is prohibited under Section 13, Rule 110§ of the Rules of Court, and that they should only be charged with a single offense—Reckless Imprudence Resulting in Damage to Property under Article 365§ of the RPC.
• Violation of the Relova Doctrine: They argued that their prosecution under multiple national statutes violates their constitutional right against multiple prosecutions as enunciated in People v. Relova, which bars harassment of an accused through overlapping sets of technical elements.
• Doctrine of Absorption: They argued that the element of "negligence, recklessness, and imprudence" under Article 365§ of the RPC is common to all charges, and therefore the RPC charge absorbs the offenses penalized under the Water Code (P.D. 1067), the National Pollution Control Decree (P.D. 984), and the Philippine Mining Act (R.A. 7942).

• No Duplicity of Charges: The prosecution argued that "duplicity of charges" arises only when a single Information charges more than one offense. In this case, each of the twelve separate Informations charged only one distinct offense; hence, there is no duplicity of offenses in a single information.
• Distinct and Separate Offenses: The prosecution contended that a single act can violate multiple distinct national statutes if each statute requires proof of an additional element that the others do not. Each of the four laws defines a separate offense with distinct elements and purposes.
• Mala In Se vs. Mala Prohibita: The prosecution argued that Article 365§ of the RPC is a malum in se felony requiring criminal negligence, whereas the offenses under the three special laws are mala prohibita which cannot be absorbed by a negligent felony.
• Inapplicability of Relova: The prosecution argued that the Relova doctrine applies only when a single act is prosecuted under both a municipal/city ordinance and a national statute. Since all four charges in this case were filed under national statutes, Relova is inapplicable.

• Factual Identity of the Incident: The parties stipulated/agreed that all the charges arose from the single incident on March 24, 1994 (or March 24, 1996), involving the spill/discharge of mine tailings from Marcopper's Mt. Tapian pit drainage tunnel into the Boac and Makalupnit rivers.

Issue

1. Whether a single act or incident can be prosecuted under multiple separate national statutes without violating the rule against double jeopardy or the doctrine in People v. Relova.
2. Whether the felony of Reckless Imprudence Resulting in Damage to Property under Article 365§ of the Revised Penal Code absorbs the mala prohibita offenses penalized under the Water Code (P.D. 1067), the National Pollution Control Decree (P.D. 984), and the Philippine Mining Act (R.A. 7942).

Ruling

• MAIN ISSUE: NO. The Supreme Court held that there is no duplicity of charges because each of the separate Informations filed against the petitioners charged only one distinct offense. Duplicity under Section 13, Rule 110§ arises only when a single Information charges more than one offense.
• SECONDARY ISSUES:
  1. YES. A single act may offend against two or more entirely distinct and unrelated provisions of law, and if one provision requires proof of an additional fact or element which the others do not, prosecution for each distinct offense is proper.
  2. NO. A mala in se felony under Article 365§ of the RPC (requiring criminal negligence) cannot absorb mala prohibita crimes under special laws, as the latter are punished by virtue of the special laws enacting them, where intent or negligence is immaterial.

"WHEREFORE, we DENY the petition. We AFFIRM the Decision dated 5 November 2001 and the Resolution dated 14 March 2002 of the Court of Appeals.

SO ORDERED."

Ratio

1. The Strict Literal Interpretation of Duplicity under Section 13, Rule 110§: The Court began by analyzing the concept of "duplicity of offenses" as defined in Section 13, Rule 110§ of the Rules of Court. It held that the rule prohibits the charging of more than one offense in a single complaint or information:

   "Duplicity of offense. — A complaint or information must charge but one offense, except only in those cases in which existing laws prescribe a single punishment for various offenses."

   The Court explained that the rationale for this prohibition is to avoid confusing the accused and to ensure that they are sufficiently informed of the precise nature of the charge to prepare a suitable defense. In this case, however, the prosecution filed twelve separate Informations, each charging only one distinct offense. Consequently, because no single Information charged more than one offense, the petitioners' invocation of duplicity as a ground to quash under Section 3(f) of Rule 117§ was structurally and procedurally untenable.
2. The "Same Evidence" or "Additional Fact" Test for Multiple Prosecutions: The Court reaffirmed the long-standing rule that a single physical act or transaction can give rise to multiple distinct offenses under different laws if each offense requires proof of an element or fact that the others do not. Citing People v. Doriquez, the Court declared:

   "where two different laws (or articles of the same code) define two crimes, prior jeopardy as to one of them is no obstacle to a prosecution of the other, although both offenses arise from the same facts, if each crime involves some important act which is not an essential element of the other."

   The Court approved the RTC's comparative analysis of the four statutes to show that each has a distinct and essential element not required by the others:
   • P.D. No. 1067 (Water Code): The additional element is the dumping of mine tailings without a prior permit from the concerned authorities. The gravamen of the offense is the absence of the proper permit. One can be prosecuted under this law even in the absence of actual pollution.
   • P.D. No. 984 (National Pollution Control Decree): The additional fact that must be proved is the existence of actual pollution. The gravamen of the offense is the pollution itself. In the absence of pollution, there is no liability under this law, even if there was unauthorized dumping or lack of precaution.
   • R.A. No. 7942 (Philippine Mining Act): The additional fact is the willful violation and gross neglect on the part of the accused to abide by the terms and conditions of the ECC (specifically, to ensure the containment of run-off).
   • Article 365§ of the RPC (Reckless Imprudence): The additional element is the lack of necessary or adequate precaution, negligence, recklessness, and imprudence on the part of the accused to prevent damage to property. This is a malum in se felony requiring proof of criminal negligence, unlike the special laws which are mala prohibita and impose strict liability. Therefore, because each statute requires proof of a distinct element, the prosecution of the petitioners under all four laws for the same underlying physical act is proper and valid.
3. The Inapplicability of the Relova Doctrine: The Court explicitly distinguished this case from People v. Relova. In Relova, the accused was prosecuted under a municipal ordinance and subsequently under a national statute (the Revised Penal Code) for the same act. The Court explained that Relova was decided under the second sentence of Section 21, Article III of the 1987 Constitution (formerly Section 22, Article IV of the 1973 Constitution), which states:

   "If an act is punished by a law and an ordinance, conviction or acquittal under either shall constitute a bar to another prosecution for the same act."

   In contrast, the petitioners in this case are being prosecuted under four national statutes. Thus, their case falls under the first sentence of Section 21, Article III, which prohibits multiple prosecutions for the "same offense." Since the offenses under the four national statutes are distinct and have different elements, they are not the "same offense," and Relova cannot be invoked to quash the charges.
4. No Absorption of Mala Prohibita by Mala In Se: The Court dismissed the petitioners' argument that the negligent felony under Article 365§ of the RPC absorbed the special law violations. Felonies under the RPC are mala in se, requiring criminal intent or negligence. In contrast, offenses under special laws are mala prohibita, where the mere commission of the prohibited act is sufficient for conviction, regardless of intent or negligence. A mala in se felony cannot absorb mala prohibita crimes, as they are distinct categories of criminal liability governed by different legal standards.

Doctrine

• The Definition of Duplicity: Duplicity of charges exists only when a single complaint or information charges more than one offense. It cannot be pleaded as a ground for quashal when the prosecution files separate sheets of Information for each offense.
• The Distinct Offenses Doctrine: A single act may offend against two or more entirely distinct provisions of law. If each law requires proof of an additional fact or element which the others do not, prosecution under all of them is proper and does not violate the rule against double jeopardy.
• The Constitutional Distinction under Section 21, Article III: The first sentence of the double jeopardy clause protects against multiple prosecutions for the same offense, allowing multiple national prosecutions for a single act if the offenses are distinct. The second sentence protects against multiple prosecutions for the same act only when one is under a local ordinance and the other is under a national statute.

• The Single Act Ordinance-Statute Bar: Under the second sentence of Section 21, Article III of the Constitution, if a single act is penalized by both a national law and a municipal or city ordinance, a conviction or acquittal under either constitutes an absolute bar to another prosecution, regardless of whether the technical elements of the offenses are different.
