Padilla, et al. vs. Congress of the Philippines

Article VII, Section 18 of the 1987 Constitution requires Congress to convene in joint session and vote jointly only when acting to revoke or extend a presidential proclamation of martial law or suspension of the privilege of the writ of habeas corpus; it does not mandate a joint session for mere deliberation or review of the proclamation's factual basis, which Congress may conduct separately in accordance with its own rules.

On May 23, 2017, President Rodrigo Roa Duterte issued Proclamation No. 216 declaring a state of martial law and suspending the privilege of the writ of habeas corpus in the whole of Mindanao following armed attacks by the Maute and Abu Sayyaf terrorist groups. This was issued pursuant to Article VII, Section 18 of the 1987 Constitution. Within forty-eight hours, the President submitted a report to Congress detailing the factual and legal basis for the declaration.

• On May 23, 2017, President Duterte issued Proclamation No. 216 declaring martial law and suspending the privilege of the writ of habeas corpus in Mindanao due to rebellion and public safety concerns.
• Within forty-eight hours, on May 25, 2017, the President transmitted his Report to Congress while Congress was in session.
• On May 29, 2017, the Senate conducted a four-hour closed-door briefing with the Secretary of National Defense, National Security Adviser, and AFP Chief of Staff.
• On May 30, 2017, the Senate deliberated on P.S. Resolution No. 388 (expressing support) and P.S. Resolution No. 390 (calling for joint session). Resolution No. 388 was adopted as Senate Resolution No. 49 with 17 affirmative votes and 5 negative votes, while P.S. Resolution No. 390 was rejected with 9 votes in favor and 12 against.
• On May 31, 2017, the House of Representatives constituted itself as a Committee of the Whole and received a six-hour briefing from Executive and security officials.
• On the same day, the House passed House Resolution No. 1050 expressing full support for the proclamation via viva voce voting and rejected a proposal to call for a joint session.
• Both Houses separately determined not to revoke Proclamation No. 216 and declined to adopt concurrent resolutions necessary to convene a joint session under their respective rules.
• On July 22, 2017, prior to the expiration of the initial 60-day period, Congress convened in joint session and extended the martial law declaration until December 31, 2017.

• The plain text of Article VII, Section 18, supported by the intent of the 1986 Constitutional Commission and the precedent in Fortun v. Macapagal-Arroyo, mandates that Congress automatically convene in joint session to deliberate and vote as a single deliberative body upon a presidential proclamation of martial law.
• The duty to convene jointly is a mandatory, ministerial constitutional duty enforceable by writ of mandamus, not a discretionary act.
• The phrase "voting jointly" necessarily implies a joint session for deliberation, as Congress cannot determine whether to revoke without first convening to deliberate.
• Separate deliberations in each House violate the public's right to information and transparent proceedings regarding the factual bases for martial law.
• Petitioners possess legal standing as citizens, taxpayers, and (for Senator De Lima) as a legislator whose constitutional prerogatives were allegedly impaired by the refusal to convene jointly.

• Article VII, Section 18 requires joint voting only for the specific actions of revoking or extending a martial law proclamation; it does not mandate a joint session for mere deliberation or review.
• The Constitution explicitly requires the President to report to Congress, but does not prescribe the manner by which Congress must review the proclamation, leaving such procedure to the discretion of each House under Article VI, Section 16(3).
• The non-convening of a joint session does not present an actual case or controversy, or alternatively, presents a political question beyond judicial review.
• Mandamus does not lie to compel the performance of a discretionary act, and certiorari does not lie absent grave abuse of discretion, as Congress acted within its constitutional authority by separately reviewing the proclamation and expressing support.
• Petitioners lack standing because they assert generalized interests rather than direct, personal injury.

• Procedural Issues:
  • Whether the Supreme Court has jurisdiction over the petitions involving the internal affairs of Congress.
  • Whether petitioners possess legal standing to file the petitions.
  • Whether the petitions are moot and academic given the expiration of the initial 60-day period and Congress's subsequent joint session to extend martial law.
  • Whether the remedies of mandamus and certiorari are available against Congress.
• Substantive Issues:
  • Whether Article VII, Section 18 of the 1987 Constitution mandates Congress to automatically convene in joint session to deliberate on a presidential proclamation of martial law or suspension of the writ of habeas corpus.

• Procedural:
  • The Court has jurisdiction to interpret constitutional provisions defining the duties of Congress, as this does not violate separation of powers but fulfills the judiciary's duty to say what the law is.
  • Petitioners have standing: citizens and taxpayers have standing to assert public rights, and legislators have standing to ensure their constitutional prerogatives remain inviolate.
  • The petitions are not moot despite supervening events because they involve issues of transcendental importance concerning the constitutional check on martial law powers, capable of repetition yet evading review.
  • Mandamus does not lie because the duty to convene jointly is not ministerial; it is discretionary when the purpose is not revocation. Certiorari does not lie because Congress did not gravely abuse its discretion in determining its own rules for reviewing the proclamation.
• Substantive:
  • The Court interpreted Article VII, Section 18 using the plain meaning rule (verba legis). The provision states: "The Congress, voting jointly, by a vote of at least a majority of all its Members in regular or special session, may revoke such proclamation or suspension..."
  • The phrase "voting jointly" and the requirement for a joint session apply specifically to the act of revocation (and by reference, extension), not to the initial deliberation or review of the proclamation.
  • The framers of the 1987 Constitution intended to remove the requirement of prior congressional concurrence for the initial imposition of martial law to allow the President to act quickly in emergencies, while providing that Congress could revoke the action jointly to prevent deadlock between the two Houses.
  • Congress may deliberate separately; the mode of deliberation is within its discretion under Article VI, Section 16(3) (each House determines its own rules). Since both Houses separately expressed support and no intent to revoke, the provision on revocation never came into operation, and there was no obligation to convene jointly.
  • The Court distinguished Fortun v. Macapagal-Arroyo, noting that in that case, the Senate had expressed intent to revoke, necessitating a joint session, whereas here, both Houses supported the proclamation.

• Separation of Powers — While courts generally respect the internal rules and autonomy of Congress, they may intervene to interpret constitutional provisions that define the scope of congressional duties and powers.
• Plain Meaning Rule (Verba Legis) — When the language of the Constitution is clear, plain, and unambiguous, it must be given its literal meaning and applied without attempted interpretation; the intent is deemed embedded in the text itself.
• Political Question Doctrine (Limited Application) — The expanded jurisdiction of the courts under Article VIII, Section 1 allows judicial review of actions by other branches even involving political questions, provided the issue involves grave abuse of discretion or requires interpretation of constitutional duties.
• Ministerial vs. Discretionary Duty — Mandamus lies only to compel the performance of a ministerial duty (a specific legal obligation performed in a prescribed manner without regard to discretion), not a discretionary act involving judgment or choice.

• "The Congress is not constitutionally mandated to convene in joint session except to vote jointly to revoke the President's declaration or suspension."
• "The plain language of the subject constitutional provision does not support the petitioners' argument that it is obligatory for the Congress to convene in joint session following the President's proclamation of martial law and/or suspension of the privilege of the writ of habeas corpus, under all circumstances."
• "The power to revoke intrinsically and logically includes the duty to deliberate on whether or not to revoke." — Associate Justice Marvic M.V.F. Leonen, Concurring and Dissenting Opinion
• "To defer to the actions of the respondents today and grant the veneer of constitutionality ensure the unworkability of the constitutional provision at bar in the future." — Associate Justice Marvic M.V.F. Leonen, Concurring and Dissenting Opinion

• Fortun v. Macapagal-Arroyo — Cited by petitioners for the phrase "automatic duty" regarding congressional review; distinguished by the Court as involving different factual circumstances where the Senate had resolved to revoke the proclamation, thereby triggering the joint session requirement.
• Civil Liberties Union v. The Executive Secretary — Cited for the principle that constitutional intent is ascertained primarily from the language of the provision itself, and that resort to framers' intent is only necessary when the text is ambiguous.
• Angara v. Electoral Commission — Cited for the classic formulation of the separation of powers doctrine and the constitutional demarcation of governmental powers.
• Belgica v. Ochoa — Cited for the reaffirmation of the separation of powers as the backbone of the tripartite system of government.

• Article VII, Section 18, 1987 Constitution — The central provision governing the President's power to declare martial law and suspend the writ of habeas corpus, and Congress's power to revoke or extend such proclamation, and the requirement for joint voting.
• Article VI, Section 16(3), 1987 Constitution — Grants each House of Congress the authority to determine the rules of its proceedings, supporting the discretion of each House to deliberate separately.
• Article III, Section 7, 1987 Constitution — The right to information on matters of public concern, discussed in relation to the public's access to congressional deliberations on martial law.

• Associate Justice Marvic M.V.F. Leonen — Concurred in the result (dismissal) on the ground of mootness but dissented on the doctrine. Argued that the power to revoke logically includes the duty to deliberate jointly; warned that allowing separate deliberations creates a risk of deadlock between the two Houses, undermines the efficiency of congressional review within the 60-day limit, and fragments the constitutional check on executive power. Maintained that Congress should automatically convene as a single body to deliberate and decide on martial law proclamations.
