Constitutional Basis

The Commander-in-Chief powers of the President of the Philippines are provided under Article VII, Section 18 of the 1987 Constitution. This section grants the President broad powers to ensure the security of the state, including the power to declare Martial Law and to suspend the privilege of the writ of habeas corpus under specific conditions.

The relevant portion of the Constitution states:

"The President shall be the Commander-in-Chief of all armed forces of the Philippines and whenever it becomes necessary, he may call out such armed forces to prevent or suppress lawless violence, invasion, or rebellion. In case of invasion or rebellion, when the public safety requires it, he may, for a period not exceeding sixty days, suspend the privilege of the writ of habeas corpus or place the Philippines or any part thereof under martial law."

Conditions for Declaration of Martial Law or Suspension of the Privilege of the Writ of Habeas Corpus

The President may declare Martial Law or suspend the privilege of the writ of habeas corpus only under two specific grounds:

Invasion, or
Rebellion, and only when public safety requires it.

Thus, the declaration of Martial Law and the suspension of the writ of habeas corpus are not discretionary powers of the President; they require the existence of actual conditions of invasion or rebellion and the additional requirement that public safety is at risk.

Invasion

Invasion refers to a situation where the sovereignty of the Philippines is under external attack by foreign forces, endangering the integrity of the nation.

Rebellion

Rebellion is defined under the Revised Penal Code (Article 134) as an act involving raising arms against the government for the purpose of removing its allegiance to the State or undermining the government’s authority.

Public Safety

The element of public safety refers to the necessity of protecting the general public from a real and imminent threat to life, property, or public order. It must be a condition present in addition to either invasion or rebellion.

Effect and Scope of Martial Law and the Suspension of the Writ of Habeas Corpus

Effect of Martial Law

Military Supremacy in Affected Areas: Martial Law imposes a regime of military authority over civilian areas. The military may take control of civil governance in areas declared under Martial Law.
Suspension of Certain Civil Rights: Certain civil liberties, including freedom of movement, may be restricted. However, Martial Law does not suspend the operation of the Constitution.

It is crucial to emphasize that under Article VII, Section 18, Martial Law does not suspend the Constitution, nor does it supplant civil courts with military tribunals where the civil courts are open and functioning. The rights of civilians, especially those not involved in the rebellion or invasion, remain protected.

Suspension of the Writ of Habeas Corpus

The writ of habeas corpus is a legal remedy against arbitrary detention, and its suspension allows authorities to detain individuals without immediately charging them with a crime.

The suspension of the writ does not apply to all arrests. It applies only to persons judicially charged for rebellion or offenses inherent in or directly connected to invasion.
Those arrested without a judicial charge must be released after three days, even if the privilege of the writ is suspended.

Duration

Initial Period: Martial Law or the suspension of the privilege of the writ of habeas corpus can only last for 60 days from the date of the declaration.
Extension: The period may be extended only upon the initiative of the President and with the concurrence of Congress. The President must submit a report to Congress within 48 hours from the declaration, either in person or in writing.
Congressional Review: Congress, voting jointly, by a majority vote of all its Members in regular or special session, may either extend or revoke the declaration.
Revocation: Congress may revoke the proclamation or suspension, and the President cannot set aside this revocation.
Supreme Court Review: Any citizen may question the sufficiency of the factual basis for Martial Law or the suspension of the writ before the Supreme Court, which must rule on the matter within 30 days from the filing of a petition.

Congressional Powers

Automatic Convening: Upon the declaration of Martial Law or the suspension of the writ of habeas corpus, Congress must automatically convene within 24 hours to consider the proclamation or suspension, even if Congress is not in session.
Authority to Revoke or Extend: Congress, through a majority vote of all its Members voting jointly, may either revoke or extend the proclamation or suspension. If revoked, the President cannot override this decision. If extended, Congress determines the period of extension.

Judicial Review

Review by the Supreme Court: The Supreme Court has the authority to review the sufficiency of the factual basis of the declaration of Martial Law or the suspension of the writ of habeas corpus.
Filing a Petition: Any citizen can file a petition questioning the sufficiency of the factual basis for Martial Law or suspension of the writ of habeas corpus. The Supreme Court is mandated to decide the matter within 30 days from the filing of the petition.

Extension and Revocation

Extension: As noted earlier, Congress may extend Martial Law or the suspension of the writ upon the President's initiative. There is no limit to how long an extension may last, provided that Congress deems it necessary and votes to approve it.
Revocation: Congress may revoke Martial Law or the suspension of the writ at any time by a majority vote of all its members voting jointly. Once revoked, the President cannot override this revocation. Moreover, if the Supreme Court finds the factual basis insufficient, it may also nullify the proclamation.

Restrictions

No Indefinite Martial Law: Martial Law cannot last indefinitely. While the initial declaration is limited to 60 days, it can only be extended upon approval of Congress.
Civilian Supremacy: Civilian authority must remain supreme even during Martial Law, and the Constitution’s provisions remain in effect, especially those protecting basic rights.
No Suspension of Judicial Processes: Even under Martial Law, the judicial processes of the country continue to function, except in places where military rule is necessary due to the breakdown of law and order. Civil courts that are operational should not be supplanted by military courts.

Historical Precedents

Proclamation No. 1081 (1972): Former President Ferdinand Marcos placed the Philippines under Martial Law, citing threats of communist rebellion and lawlessness. This period was marked by widespread human rights violations, emphasizing the potential dangers of unchecked Martial Law powers.
2017 Mindanao Martial Law: President Rodrigo Duterte declared Martial Law in Mindanao in response to the Marawi siege by the Maute group, citing rebellion. This was extended multiple times by Congress, but remained limited to the Mindanao region and did not encompass the entire Philippines.

Conclusion

The Commander-in-Chief powers of the President, particularly the declaration of Martial Law and the suspension of the writ of habeas corpus, are extraordinary measures that are constitutionally confined to specific circumstances—namely invasion or rebellion when public safety requires it. The 1987 Constitution provides safeguards such as judicial and legislative checks to prevent abuse of these powers. The Philippine legal framework ensures that even in times of crisis, the rule of law prevails, and civil liberties are not unduly trampled.
