The declaration of martial law is the most potent extraordinary power of the President of the Philippines. Historically shadowed by the abuses of the 1972 Marcos regime, the 1987 Philippine Constitution was specifically engineered with multiple "safety switches" to ensure that the suspension of certain legal procedures does not result in the total collapse of civil liberties.
1. The Constitutional Basis and Grounds
Under Article VII, Section 18 of the 1987 Constitution, the President, as Commander-in-Chief, may suspend the privilege of the writ of habeas corpus or place the Philippines or any part thereof under martial law. However, this is restricted to two specific conditions:
- Invasion or Rebellion: When actual (not merely imminent) hostilities exist.
- Public Safety Requirement: The gravity of the situation must necessitate the declaration to ensure the safety of the populace.
2. The "No-Supplanting" Principle
A common misconception is that martial law replaces the entire civilian government with military rule. The Constitution explicitly negates this:
- Civil Courts and Legislatures: Martial law does not suspend the operation of the Constitution, nor does it supplant the functioning of the civil courts or legislative assemblies.
- Military Jurisdictions: Military courts have no jurisdiction over civilians as long as civil courts are able to function. The civilian authority remains supreme over the military at all times.
3. Suspension of the Privilege of the Writ of Habeas Corpus
While martial law and the suspension of the privilege of the writ of habeas corpus often go hand-in-hand, they are distinct legal actions.
The Scope of Suspension
The suspension of the privilege does not mean the writ itself is gone; it means the court’s ability to order the immediate release of a person is restricted. However, this is strictly qualified:
- Limited Applicability: The suspension applies only to persons "judicially charged for rebellion or offenses inherent in or directly connected with invasion."
- The Three-Day Rule: Any person arrested or detained during the suspension must be judicially charged within three days (72 hours). If no charges are filed within this window, the person must be released. Failure to do so constitutes an illegal detention.
4. The Trinity of Safeguards
The 1987 Constitution established a tripartite system of checks and balances to prevent Executive overreach:
I. The Temporal Safeguard
A declaration of martial law is valid for a maximum of 60 days. Any extension requires the explicit approval of Congress.
II. Legislative Oversight
- Review and Revocation: Within 48 hours of the declaration, the President must submit a report (in person or in writing) to Congress.
- Joint Session: Congress, voting jointly, has the power to revoke the proclamation. The President cannot set aside this revocation.
III. Judicial Review
The Supreme Court is empowered to review the sufficiency of the factual basis of the proclamation or the suspension of the privilege of the writ. Any citizen may file a petition, and the Court must promulgate its decision within 30 days.
5. Civil Rights During Martial Law
Despite the heightened security state, fundamental rights enshrined in the Bill of Rights (Article III) remain operative:
| Right | Status During Martial Law |
|---|---|
| Right to Bail | The right to bail remains available even when the privilege of the writ of habeas corpus is suspended. |
| Right against Torture | Absolute and non-derogable; no state of emergency justifies "extraordinary" interrogation. |
| Freedom of Speech | Remains protected; martial law does not authorize prior restraint or censorship of the press. |
| Right to Counsel | All persons under investigation for the commission of an offense must still be informed of their right to remain silent and to have competent and independent counsel. |
6. Procedural Shifts and Military Involvement
In practice, the declaration allows the military to perform functions usually reserved for the police, such as:
- Establishing Checkpoints: Heightened security checks for arms and contraband.
- Curfews: Restricted movement to isolate insurgents or invaders.
- Warrantless Arrests: Permissible only under the strict conditions of Rule 113, Section 5 of the Rules of Court (in flagrante delicto, hot pursuit, or escaped prisoner), unless the privilege of the writ is also suspended and the person is linked to rebellion/invasion.
Conclusion
In the Philippine legal context, martial law is a "law of necessity." It is a tool for the preservation of the State, not a license for the dissolution of the law. The 1987 Constitution ensures that while the President may wield the sword to defend the Republic, the shield of the Bill of Rights remains firmly in the hands of the citizenry.
