Lagman vs. Medialdea

The Constitution imposes no limit on the number or total duration of extensions of martial law that Congress may approve, provided that (a) the extension is upon the President's initiative, (b) rebellion or invasion persists and public safety requires it, and (c) the extension is subject to judicial review for sufficiency of factual basis. The Court's review power under Section 18, Article VII is limited to determining the sufficiency, not the accuracy or correctness, of the factual basis for the proclamation or extension.

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 entire Mindanao for a period not exceeding sixty days. The proclamation cited attacks by the Maute Group and Abu Sayyaf Group (ASG) in Marawi City, including the takeover of a hospital, establishment of checkpoints, burning of facilities, and flying of the ISIS flag, constituting rebellion. The President submitted his report to Congress within 48 hours as required by the Constitution. Congress, through Senate Resolution No. 388 and House Resolution No. 1050, found no cause to revoke the proclamation.

• The Third Extension Request: On December 4, 2018, Secretary of National Defense Delfin N. Lorenzana recommended to the President the third extension of martial law for one year (January 1 to December 31, 2019) to address continuing rebellion by DAESH-inspired groups (Daulah Islamiyah), local terrorist groups (LTGs), and Communist Party of the Philippines-New People's Army Terrorists (CNTs). AFP Chief of Staff General Carlito G. Galvez, Jr. and PNP Director-General Oscar D. Albayalde supported the recommendation, citing 137 violent incidents by LTGs and 177 by CTRGs from January to November 2018, including bombings, kidnappings, ambuscades, and arson.
• President's Letter to Congress: In his December 6, 2018 letter to Congress, the President cited specific incidents: the Lamitan City bombing (July 31, 2018) killing 11; Isulan IED explosions (August 28 and September 2, 2018) killing 5 and wounding 45; Barangay Apopong IED explosion wounding 8; 342 violent incidents by communist groups killing 87 soldiers; and ongoing recruitment and radicalization activities. He noted that 181 persons in martial law arrest orders remained at large.
• Congressional Approval: On December 12, 2018, the Senate and House of Representatives convened in joint session and adopted Resolution of Both Houses No. 6 by 235 affirmative votes, extending martial law for one year based on findings that rebellion persisted and public safety required it.
• Petitioners' Allegations: Petitioners, members of the House of Representatives, filed consolidated petitions assailing the extension, arguing that no actual rebellion existed post-Marawi, that the extension violated the constitutional proscription against indefinite martial law, and that Congress acted hastily without sufficient factual basis.

• Independent Judicial Determination: Petitioners maintained that the Court must independently determine the sufficiency of the factual basis for the extension, not merely defer to the Executive and Legislative branches' declarations, in fulfillment of its role as ultimate guardian of the Constitution.
• Absence of Actual Rebellion: Petitioners argued that the acts of lawlessness cited by the President were isolated incidents of terrorism or common crimes, not constituting rebellion under Article 134 of the Revised Penal Code, and could be addressed through the President's calling out power.
• Lack of Public Safety Requirement: The alleged rebellion did not endanger public safety to the extent that government could not function; courts and government offices remained operational.
• Functus Officio: Proclamation No. 216 became functus officio upon the cessation of combat operations in Marawi and the death of terrorist leaders (Hapilon and the Maute brothers), rendering further extensions unnecessary.
• Constitutional Limit on Duration: The constitutional 60-day limit implies that extensions must also be of short duration; a cumulative 951-day martial law regime violates the constitutional intent for temporary emergency measures.
• Grave Abuse of Discretion: Congress committed grave abuse of discretion by approving the extension hastily without thorough deliberation or specific detailed reports from the President.
• Human Rights Violations: The extension would perpetuate human rights abuses, warranting nullification to protect citizens' rights.

• Limited Judicial Review: Respondents, through the Office of the Solicitor General, countered that the Court's power under Section 18, Article VII is limited to determining the sufficiency of the factual basis, not the correctness of the President's decision.
• Persistence of Rebellion: Rebellion continued through the activities of LTGs (ASG, BIFF, DI) and CTRGs (CPP-NPA), including recruitment, radicalization, bombings, and armed encounters, as documented in military and police reports.
• Public Safety Necessity: The spate of violence, kidnappings, and destruction of property demonstrated that public safety required the extension to prevent escalation and allow rehabilitation.
• No Constitutional Limit on Extensions: The Constitution does not limit the number or duration of extensions; Congress has sole prerogative to determine the period upon the President's initiative.
• Political Question: The manner by which Congress conducted its joint session, including rules of procedure and deliberation, is a political question not subject to judicial review under Section 16, Article VI.
• Availability of Remedies: Alleged human rights violations do not nullify the extension; adequate legal safeguards and remedies (writ of amparo, habeas data, anti-torture laws) are available to address specific abuses.

• Sufficiency of Factual Basis: Whether sufficient factual basis exists for the third extension of martial law in Mindanao, specifically whether rebellion persists and public safety requires the extension.
• Constitutional Limits on Extensions: Whether the Constitution limits the number or duration of extensions of martial law that Congress may grant.
• Functus Officio: Whether Proclamation No. 216 became functus officio with the cessation of the Marawi siege and death of terrorist leaders.
• Political Question: Whether the manner by which Congress approved the extension constitutes a non-justiciable political question.
• Grave Abuse of Discretion: Whether the extension was attended by grave abuse of discretion on the part of Congress.
• Human Rights Violations: Whether allegations of human rights violations in the implementation of martial law warrant nullification of the extension.

• Sufficiency of Factual Basis: Sufficient factual basis exists for the extension. Rebellion persists through the coordinated activities of Local Terrorist Rebel Groups (ASG, BIFF, DI) and Communist Terrorist Rebel Groups (CPP-NPA-NDF), evidenced by 314 violent incidents in 2018 including bombings, ambuscades, kidnappings, and recruitment activities. Public safety requires the extension, as evidenced by resolutions from Regional and Provincial Peace and Order Councils and the continuing threat to security.
• Constitutional Limits on Extensions: The Constitution imposes no limit on the number or total duration of extensions. The framers deliberately rejected a 60-day limitation on extensions, granting Congress flexibility to determine the period upon the President's initiative, provided rebellion persists and public safety requires it.
• Functus Officio: Proclamation No. 216 did not become functus officio. Rebellion is a continuing crime that transcends specific localities; the cessation of the Marawi siege did not terminate the broader rebellion waged by affiliated and other rebel groups throughout Mindanao.
• Political Question: The manner by which Congress conducted its joint session, including rules of procedure and deliberation, is a political question not reviewable by the Court in the absence of constitutional violation or denial of due process.
• Grave Abuse of Discretion: No grave abuse of discretion attended the approval of the extension. Congress acted within its constitutional authority based on the President's request and supporting security reports.
• Human Rights Violations: Allegations of human rights violations are insufficient to nullify the extension. The Bill of Rights remains in effect during martial law, and specific remedies (writs of amparo and habeas data, anti-torture laws) are available to address individual abuses without invalidating the proclamation itself.

• Standard of Review in Martial Law Cases: Judicial review under Section 18, Article VII is limited to determining the sufficiency, not the accuracy or correctness, of the factual basis for the proclamation or extension of martial law. The Court assesses whether the President acted arbitrarily, not whether the decision was correct.
• Nature of Rebellion: Rebellion under Article 134 of the Revised Penal Code is a continuing crime consisting of a public uprising and taking arms against the Government for the purpose of removing territory or armed forces from allegiance, or depriving the Chief Executive or Legislature of powers. It is not confined to specific localities or time periods of actual fighting, and includes clandestine activities such as recruitment, financing, and propaganda.
• Totality of Circumstances Test: In assessing sufficiency of factual basis, the Court must view reported incidents in their totality, not as isolated events, to determine if they constitute a consistent pattern of rebellion.
• Political Question Doctrine: Congress has full discretionary authority under Section 16, Article VI to determine its own rules of proceedings; the exercise of this power is exempt from judicial interference absent a clear showing of arbitrary use constituting denial of due process or violation of constitutional provisions.
• Quantum of Proof: The President need only satisfy himself of probable cause or evidence showing that more likely than not rebellion exists; proof beyond reasonable doubt is not required.

• "The test of sufficiency is not accuracy nor preciseness but reasonableness of the factual basis adopted by the Executive in ascertaining the existence of rebellion and the necessity to quell it."
• "Rebellion, within the context of the situation in Mindanao, encompasses no definite time nor particular locality of actual war and continues even when actual fighting has ceased."
• "The Constitution imposes no limit on the number or total duration of extensions Congress may grant, provided rebellion persists and public safety requires it."
• "The Court must not fall into or be tempted to substitute Our own judgment to that of the People's President and the People's representatives."
• "The visible and invisible facets of rebellion... it is difficult, if not impossible, to fix the territorial scope of martial law in direct proportion to the 'range' of actual rebellion and public safety simply because rebellion and public safety have no fixed physical dimensions."

• Lagman v. Medialdea, G.R. Nos. 231658, 231771 and 231774, July 4, 2017 — Controlling precedent establishing the standard of review (sufficiency of factual basis, not correctness) and defining rebellion in the context of the 1987 Constitution.

• Section 16(3), Article VI, 1987 Constitution — Grants each House of Congress the power to determine its own rules of proceedings.
• Article 134, Revised Penal Code — Defines rebellion or insurrection as rising publicly and taking arms against the Government for the purpose of removing territory or armed forces from allegiance or depriving the Chief Executive or Legislature of powers.
