Lagman vs. Medialdea

By Michael Henry Yusingco, LL.M

Our information ecosystem today is shaped by journalists, social media influencers, and political actors. Believe it or not, the Supreme Court also impacts public discourse. Judicial decisions determine what the state may conceal, what it may regulate, and how much institutional scepticism democratic systems are willing to tolerate.

Specifically in cases involving national security, the Supreme Court confronts a difficult choice between constitutional scrutiny and executive deference. Lagman vs. Medialdea (G.R. No 231658, 4 July 2017) illustrates how choosing the latter can influence not merely the legality of state action, but the broader information ecosystem itself.

This case arose from the declaration of martial law in Mindanao following the siege of Marawi by Islamist militants in 2017. Petitioners challenged the factual basis of President Rodrigo Duterte’s proclamation, arguing that the constitutional requirements for martial law had not been sufficiently established. The Supreme Court ultimately upheld the declaration, adopting a deferential posture toward executive findings regarding security threats and military necessity.

While the Supreme Court recognized its authority to review the factual basis of martial law under the 1987 Constitution, it applied that power cautiously, emphasizing institutional limitations and the executive’s superior access to intelligence and operational information.

On one level, this deference is understandable. Courts are not military institutions. Judges do not command troops, gather battlefield intelligence, or manage real-time security operations. Democratic constitutions therefore often permit some degree of executive flexibility during national security emergencies.

The problem emerges when deference devolves from institutional prudence into informational asymmetry so severe that meaningful constitutional scrutiny becomes difficult. In such situations, the Supreme Court reinforces state narratives by automatically conceding complete trust to the administration’s determination and disclosure of the underlying facts.

This dynamic matters deeply in a degraded information ecosystem like ours. Modern democratic discourse increasingly depends on the credibility of institutions capable of producing authoritative information. During crises, governments possess immense narrative advantages: access to classified intelligence, command over law enforcement agencies, and influence over public communication systems.

Lagman vs. Medialdea demonstrates this tension clearly. Notably, the Supreme Court made it clear here that total deference to the President is the doctrine that must be followed:

“After all, the Court’s review is confined to the sufficiency, not accuracy, of the information at hand during the declaration or suspension; subsequent events do not have any bearing insofar as the Court’s review is concerned.”

The Supreme Court simply accepted broad executive assertions regarding the scale and scope of the threat in Mindanao, despite concerns raised about whether the factual basis extended beyond Marawi itself. In doing so, the decision reinforced the constitutional legitimacy of the administration’s framing of the crisis.

When the Supreme Court defers heavily to executive claims without demanding substantial public justification, the judiciary may inadvertently strengthen the state’s ability to shape political narratives with limited independent verification. And crippling civil society’s ability to challenge the government’s official narratives can lead to the further degrading of an already corrupted information ecosystem.

This does not necessarily mean the Supreme Court acted incorrectly as a matter of constitutional law. The issue is more structural: judicial deference can amplify official narratives because the Supreme Court itself remains among the most authoritative institutions within a democratic system. Once judicial approval is granted, public contestation becomes significantly harder.

Still, it would be simplistic to argue that the Supreme Court should abandon all deference during emergencies. Excessively aggressive judicial intervention may undermine legitimate security operations and push courts beyond their institutional competence. The deeper issue is whether deference is accompanied by sufficient safeguards against narrative monopolization.

Keep in mind, however, that the 1987 Constitution itself emerged partly as a response to the abuses of the Marcos dictatorship, where judicial deference enabled authoritarian consolidation under the language of national security and public order. The framers attempted to prevent a repetition of that experience by granting the Supreme Court explicit authority to review the factual basis of martial law declarations.  

Ultimately, judicial deference shapes the information ecosystem because they influence which narratives acquire institutional legitimacy and which remain contestable. The Supreme Court does not merely interpret the constitution and laws; they also attribute public credibility. In democratic societies already struggling with disinformation and declining trust, that function carries enormous consequences.
