When people hear the words insurgent, belligerent, or national liberation movement, they often assume these labels automatically give an armed group the same legal standing as a country. That is not how international law or Philippine law works. A non-state armed group may acquire limited rights and duties under the laws of armed conflict without becoming a state, gaining sovereignty, receiving diplomatic immunity, or escaping prosecution under Philippine criminal law. The key is to separate three different questions: what the group is called, whether international humanitarian law applies to the conflict, and whether any government has formally recognized a special international status.

What international legal personality means

International legal personality is the capacity of an entity to possess rights, duties, and legal capacities under international law.

States have the fullest form of international legal personality. They can enter treaties, establish diplomatic relations, claim sovereign immunity, and participate in international organizations.

Other entities may have only limited or functional personality. These may include:

International organizations
Certain peoples exercising the right to self-determination
National liberation movements in narrowly defined circumstances
Insurgent or belligerent groups for particular humanitarian or conflict-related purposes
Individuals who may bear direct responsibility for genocide, war crimes, or crimes against humanity

International legal personality is therefore not always an all-or-nothing concept. An armed group may be bound by humanitarian rules and may be capable of entering a ceasefire or humanitarian agreement, while still lacking statehood, diplomatic recognition, or immunity from prosecution.

This distinction is especially important in the Philippines because Article II, Section 2 of the 1987 Constitution adopts generally accepted principles of international law as part of Philippine law. Philippine courts and government agencies may therefore apply international humanitarian law alongside statutes such as Republic Act No. 9851. (Lawphil)

Insurgents, belligerents, and national liberation movements compared

Category	Basic meaning	Typical legal threshold	Possible international effect
Insurgents	An organized group using armed force against an established government	Sufficient organization and sustained armed violence may create a non-international armed conflict	The group and government become bound by applicable international humanitarian law
Belligerents	A highly organized armed opposition historically recognized as a party to a civil war	Traditionally requires organized command, substantial territorial control, sustained hostilities, and recognition	May produce broader law-of-war and neutrality consequences, but not automatic statehood
National liberation movements	Movements representing peoples fighting colonial domination, alien occupation, or racist regimes	Must fall within the narrow situations covered by Article 1(4) of Additional Protocol I	May participate in an international armed conflict framework and assume treaty rights and duties through the required declaration

The labels sometimes overlap in political discussion, but their legal meanings and consequences are different.

The Philippine legal framework

The Constitution and customary international law

The Constitution declares that the Philippines adopts generally accepted principles of international law as part of the law of the land. This is often called the incorporation clause.

In Kuroda v. Jalandoni, the Supreme Court recognized that generally accepted principles and customs governing warfare may bind the Philippines even when the relevant rules are not found in an ordinary domestic statute. The case remains an important foundation for applying the laws and customs of war in Philippine law. (Lawphil)

Common Article 3 of the Geneva Conventions

Common Article 3 applies to an armed conflict that is not international in character and occurs within the territory of a state party. It establishes minimum protections for persons who are not actively participating in hostilities, including captured fighters, wounded persons, and civilians.

It prohibits:

Murder and other violence against life and person
Mutilation, cruel treatment, and torture
Hostage-taking
Humiliating or degrading treatment
Executions without judgment by a regularly constituted court
Failure to collect and care for the wounded and sick

Most importantly, Common Article 3 states that applying these protections does not affect the legal status of the parties. A government can comply with humanitarian law without recognizing the armed group as a legitimate government, state, or belligerent. (Lawphil)

Additional Protocol II

Additional Protocol II applies to certain non-international armed conflicts occurring within a state.

Its threshold is higher than the minimum threshold under Common Article 3. It generally requires fighting between state armed forces and organized armed groups that:

Operate under responsible command
Exercise enough control over part of the territory
Conduct sustained and coordinated military operations
Can implement the Protocol

The Protocol does not apply to ordinary riots, isolated violence, demonstrations, or sporadic criminal acts. The Philippines deposited its accession on December 11, 1986, and the Protocol entered into force for the country on June 11, 1987. (Lawphil)

Additional Protocol I and national liberation conflicts

Additional Protocol I mainly governs international armed conflicts.

Article 1(4) extends that framework to conflicts in which peoples fight against:

Colonial domination
Alien occupation
Racist regimes

The struggle must be connected with the exercise of the right of self-determination. This is a narrow legal category. It does not automatically include every separatist movement, communist insurgency, autonomy campaign, religious armed group, or opposition force.

Under Article 96(3), an authority representing a people engaged in a qualifying conflict may make a unilateral declaration addressed to the treaty depositary. Once effective, the Geneva Conventions and Additional Protocol I become applicable to the conflict, and the authority assumes corresponding treaty rights and obligations.

The Philippines ratified Additional Protocol I on March 30, 2012, and it entered into force for the Philippines on September 30, 2012. (Lawphil)

Republic Act No. 9851

Republic Act No. 9851, enacted in 2009, is the main Philippine statute criminalizing serious violations of international humanitarian law, genocide, and crimes against humanity.

The law recognizes that an armed conflict may involve protracted armed violence between government authorities and organized armed groups. It excludes internal disturbances such as riots, isolated incidents, and sporadic violence from the definition of armed conflict.

RA 9851 expressly provides that its application:

Does not affect the legal status of the parties
Does not imply recognition of belligerency
Does not limit the Philippine Government’s responsibility to maintain or restore law and order
Does not prevent lawful measures to defend national unity and territorial integrity

This means Philippine authorities may prosecute war crimes or enforce humanitarian protections without conceding that an armed group is a sovereign entity or recognized belligerent. (Lawphil)

What is an insurgent?

An insurgent is generally a member of an organized movement engaged in sustained armed opposition against an established government.

The term is often descriptive rather than a formal legal status. Philippine statutes do not provide a single procedure through which a group applies to be declared an “insurgent organization.”

A group described as insurgent may range from a relatively small armed organization to a force capable of conducting prolonged military operations. What matters for international humanitarian law is not merely the label but the facts on the ground.

Relevant factors include:

The intensity and duration of fighting
The frequency and seriousness of armed encounters
The group’s command structure
Its capacity to plan and coordinate operations
Its ability to recruit, train, and discipline members
Its capacity to implement humanitarian rules
The government forces deployed against it

An insurgent group does not need diplomatic recognition before Common Article 3 can apply. Once the factual threshold of a non-international armed conflict is met, both government forces and the organized armed group must observe applicable humanitarian rules.

Insurgency is different from rebellion under Philippine criminal law

Article 134 of the Revised Penal Code defines rebellion or insurrection as publicly rising and taking arms against the Government for specified political purposes, such as removing Philippine territory or armed forces from allegiance to the Government or depriving the President or Congress of their powers.

This is a domestic criminal definition. It is not the same as international recognition of insurgency or belligerency.

A person may be charged with rebellion under Philippine law even though the armed group has no separate international legal personality. Conversely, the fact that humanitarian law applies to a conflict does not prevent prosecution for rebellion or other domestic offenses. (Lawphil)

What is belligerency?

Belligerency is a more developed and historically significant status than ordinary insurgency. It traditionally arises when a civil conflict has reached a scale resembling war and an organized opposition is recognized as a belligerent party.

Traditional indicators include:

A substantial armed conflict rather than isolated unrest
An organized authority and responsible military command
Effective control over a meaningful part of the state’s territory
Sustained military operations
Capacity and willingness to observe the laws and customs of war
Recognition by the territorial state or, in some circumstances, by another state

No single factor automatically establishes belligerency. Recognition is a deliberate legal and political act, not merely a conclusion that can be drawn from the size, age, or publicity of an insurgency.

Historically, recognition of belligerency could trigger consequences involving neutrality, maritime operations, detention, and the legal treatment of the parties by third states. Modern humanitarian law has reduced the need for such recognition because Common Article 3 imposes minimum protections based on factual conditions rather than political recognition.

Recognition of belligerency does not create a new state

Even where belligerency is recognized, it does not necessarily mean that:

The group becomes a sovereign country
Its controlled territory becomes independent
Its leaders obtain diplomatic immunity
Its documents become valid passports
Its members receive permanent immunity from prosecution
Other states must establish diplomatic relations with it

Recognition of belligerency is concerned mainly with the legal consequences of an ongoing conflict. Recognition of statehood is a separate and much broader matter.

Is an armed group a belligerent simply because it controls territory?

No. Territorial control is relevant, but it is not enough by itself.

A criminal organization, private militia, or armed faction may temporarily control a community without acquiring belligerent status. Authorities must also examine the group’s organization, command structure, military operations, capacity to implement humanitarian law, and whether any legally meaningful recognition has occurred.

Under RA 9851, applying the laws of armed conflict cannot be treated as implied recognition of belligerency.

What is a national liberation movement?

A national liberation movement is an organization claiming to represent a people engaged in a struggle for self-determination.

In ordinary political language, the term may be used broadly. Under Additional Protocol I, however, the relevant legal category is much narrower. It concerns peoples fighting colonial domination, alien occupation, or racist regimes.

A group does not qualify merely because it:

Seeks independence or autonomy
Claims to represent an ethnic or religious community
Opposes the current government
Controls territory
Has foreign supporters
Calls itself a liberation front
Participates in peace negotiations

The legal inquiry focuses on the nature of the domination or occupation, the people represented, the right to self-determination being asserted, and compliance with the treaty mechanism.

The Article 96(3) declaration

For a qualifying movement, Article 96(3) permits the authority representing the people to address a declaration to the depositary of the Geneva Conventions and Additional Protocol I.

The declaration is significant because it can make the Conventions and Protocol applicable to the conflict on a reciprocal basis. The movement then assumes treaty obligations, including obligations concerning:

Protection of civilians
Treatment of prisoners and detainees
Conduct of hostilities
Protection of medical personnel and facilities
Command responsibility
Compliance by its armed forces

This mechanism is not a shortcut to statehood or membership in the United Nations. It primarily places the conflict and the participating authority within the treaty’s humanitarian framework.

How to determine the possible status of an armed group

There is no Philippine government form titled “Application for Belligerent Status.” There is also no fixed filing fee, processing period, or certificate issued by a barangay, court, the Department of Foreign Affairs, or the Armed Forces.

Status is assessed through legal and factual analysis.

Step 1: Identify the nature and intensity of the violence

Determine whether the situation involves:

Demonstrations or civil unrest
Isolated terrorist or criminal attacks
Sporadic clashes
Protracted armed violence
Sustained military operations between organized parties

Riots and isolated violence generally do not amount to an armed conflict under RA 9851 or Additional Protocol II.

Step 2: Examine the organization of the armed group

Relevant evidence may include:

Identifiable commanders and chains of command
Written or recorded orders
Internal rules and disciplinary systems
Recruitment and training structures
Units capable of coordinated operations
Mechanisms for detention, negotiation, or humanitarian coordination
Ability to communicate and implement orders across units

A group does not need to operate like a conventional army, but it must have enough organization for its operations and humanitarian obligations to be meaningfully attributed to it.

Step 3: Examine territorial control

Territorial control becomes particularly important when assessing the higher threshold of Additional Protocol II or traditional belligerency.

The question is not simply whether armed members occasionally enter an area. Authorities examine whether the group can maintain an operational presence, conduct sustained activities, administer forces, and implement humanitarian obligations.

Step 4: Identify the applicable legal framework

Depending on the facts, the situation may fall under:

Philippine criminal law only
Common Article 3
Common Article 3 and Additional Protocol II
Additional Protocol I in a qualifying international or national liberation conflict
RA 9851 and other domestic statutes
More than one framework at the same time

Domestic criminal law and international humanitarian law can apply simultaneously.

Step 5: Look for formal acts, not political claims

Useful documents may include:

Official government proclamations or diplomatic communications
Treaty declarations
Statements by foreign governments
Peace agreements or ceasefires
United Nations documents
Court decisions
Official military and humanitarian assessments

A movement’s own declaration that it is a “state,” “government,” or “belligerent” is not conclusive.

Step 6: Separate humanitarian status from criminal labels

The following questions must be analyzed separately:

Is there an armed conflict?
Is the group organized enough to be a party to that conflict?
Has belligerency been formally recognized?
Does the group qualify as a national liberation movement under treaty law?
Has a person committed rebellion, terrorism, murder, kidnapping, or another domestic offense?
Has a war crime or crime against humanity been committed?

A person or group may fall within more than one legal framework. One label does not automatically cancel the others.

Step 7: Identify the specific legal consequence being claimed

Status disputes usually arise because someone is claiming a particular right or consequence, such as:

Prisoner-of-war treatment
Immunity from ordinary prosecution
Humanitarian access
Protection of medical personnel
Validity of a ceasefire
Authority to enter an agreement
Neutrality obligations of another state
Criminal responsibility for attacks on civilians

The answer may differ depending on the legal consequence being requested.

What international humanitarian law changes—and what it does not

Issue	Effect of IHL applying to a non-state armed group
Humane treatment of persons in custody	Required
Protection of civilians	Required
Care for wounded and sick persons	Required
Prohibition against torture and summary execution	Required
Prosecution for war crimes	Possible
Command responsibility	Possible
Automatic recognition as a state	No
Automatic recognition as a belligerent	No
Automatic diplomatic immunity	No
Automatic immunity from Philippine criminal law	No
Automatic prisoner-of-war status in an ordinary non-international armed conflict	No
Ownership or sovereignty over controlled territory	No

The legal system deliberately separates humanitarian protection from political legitimacy. Otherwise, governments might resist applying humanitarian rules out of fear that humane treatment would legitimize an armed group.

Practical Philippine scenarios

A captured member of an armed group

A captured fighter must be treated humanely. Torture, disappearance, cruel treatment, hostage-taking, and execution without a proper judicial process are prohibited.

However, in an ordinary non-international armed conflict, the person does not automatically receive prisoner-of-war status or combatant immunity. Philippine authorities may investigate and prosecute the person for rebellion, illegal possession of firearms, homicide, kidnapping, terrorism-related offenses, or other crimes when supported by admissible evidence.

Philippine jurisprudence recognizes a political-offense doctrine under which certain acts committed in furtherance of rebellion may, depending on the allegations and evidence, be absorbed into rebellion. The doctrine associated with People v. Hernandez concerns domestic criminal charging. It does not grant an armed group international recognition or erase liability for war crimes under RA 9851. (Lawphil)

Civilians living in an area affected by conflict

A person does not lose civilian protection merely because:

The person lives in a community influenced by an armed group
A relative is suspected of being a fighter
The person provides ordinary food, shelter, or medical assistance under coercion
The person holds political views sympathetic to one side
The person attends a public meeting

The legal question is whether the civilian directly participates in hostilities and, if so, for what period. Mere suspicion, association, or residence does not justify torture, disappearance, collective punishment, or indiscriminate attack.

A peace agreement with an armed movement

A government may negotiate with a non-state armed group without recognizing it as a state.

Ceasefires, humanitarian agreements, and peace negotiations can be legally and practically necessary. They do not automatically grant sovereignty.

In Province of North Cotabato v. Government of the Republic of the Philippines Peace Panel, the Supreme Court examined whether proposed commitments under the Memorandum of Agreement on Ancestral Domain exceeded constitutional limits. The Court emphasized that executive negotiations cannot create an entity with sovereign or state-like powers beyond what the Constitution permits. (Lawphil)

A child recruited or used by an armed group

Republic Act No. 11188 provides special protection for children in situations of armed conflict. Children involved in, affected by, or displaced by armed conflict are treated as victims.

Recruitment and use of children by state or non-state forces are prohibited. When a child is captured, rescued, surrendered, or separated from an armed group, the response should prioritize protection, recovery, rehabilitation, and reintegration rather than treating the child in the same manner as an adult combatant. The Department of Social Welfare and Development and the Inter-Agency Committee on Children in Situations of Armed Conflict have important roles in these cases. (Supreme Court E-Library)

A foreign national accused of an international crime

RA 9851 may apply even when the accused is not Filipino.

Philippine courts may exercise jurisdiction when:

The accused is a Filipino citizen
The accused is present in the Philippines, regardless of citizenship or residence
The victim is a Filipino citizen

Cases under RA 9851 fall within the original and exclusive jurisdiction of designated Regional Trial Courts. The law also provides for investigation and prosecution by designated government authorities. (Lawphil)

Liability of commanders and individual members

Recognition disputes do not shield individuals from criminal responsibility.

Under RA 9851, a person may be liable for:

Directly committing an international crime
Ordering, inducing, or soliciting its commission
Aiding or assisting its commission
Contributing to a crime committed by a group
Attempting certain offenses
Failing, as a commander or superior, to prevent or repress crimes committed by subordinates under the legal requirements for superior responsibility

The law applies to state officials and non-state actors. A commander cannot avoid responsibility merely by arguing that the armed group lacks recognized international personality.

RA 9851 also provides that covered crimes do not prescribe, meaning the passage of time does not automatically extinguish criminal liability. Victims and witnesses are entitled to protective measures, and courts may order appropriate reparations. (Lawphil)

Government offices involved in the Philippines

Office or institution	Typical role
Department of Foreign Affairs	Treaty interpretation, diplomatic communications, international recognition issues, and dealings with treaty depositaries
Department of National Defense and Armed Forces of the Philippines	Operational assessment of armed conflict, military implementation of IHL, and documentation of hostilities
Department of Justice, Philippine National Police, and National Bureau of Investigation	Criminal investigation and prosecution under Philippine law
Commission on Human Rights	Documentation and investigation of human-rights and humanitarian-law violations within its mandate
Regional Trial Courts	Trial of offenses under RA 9851 through courts designated under the law
Department of Social Welfare and Development	Protection, rehabilitation, and reintegration of conflict-affected children and vulnerable civilians
Office of the Presidential Adviser on Peace, Reconciliation and Unity	Peace negotiations, ceasefire mechanisms, and peace-process coordination
Inter-Agency Committee on International Humanitarian Law	Government coordination, policy advice, education, monitoring, and compliance reporting

Executive Order No. 77, issued in 2024, reorganized the Philippine Inter-Agency Committee on International Humanitarian Law. It is co-chaired by the Department of National Defense and the Department of Foreign Affairs and includes agencies involved in justice, policing, health, social welfare, indigenous peoples, education, peace processes, and human rights. (Lawphil)

Evidence commonly needed in an actual investigation

There is no universal document checklist for proving insurgency or belligerency. The evidence depends on the issue being investigated.

Commonly relevant materials include:

Incident reports and police blotters
Military after-operation reports
Medical and autopsy records
Photographs, videos, satellite data, and geolocation evidence
Witness affidavits
Command orders and internal communications
Organizational charts
Training manuals and codes of conduct
Proof of territorial presence or administration
Records of detention or prisoner exchanges
Ceasefire and peace-agreement documents
Public declarations and diplomatic communications
Forensic evidence linking weapons or ammunition to an incident
Evidence showing whether an attack was directed at a military target or civilians

In practice, major bottlenecks include insecurity at incident sites, delayed access to witnesses, displacement of communities, fear of retaliation, loss of digital evidence, incomplete medico-legal documentation, and breaks in the chain of custody.

Affidavits intended for court use will normally need to comply with Philippine procedural rules. Foreign-issued public documents may require an apostille or other authentication, depending on the issuing country and the purpose for which the document will be used.

There is no fixed timeline for determining the international status of an armed group. A criminal complaint may be filed as soon as sufficient evidence is available, but complex conflict-related investigations can take substantially longer because they often involve remote locations, multiple incidents, classified information, and numerous witnesses.

Common mistakes to avoid

Assuming every rebel group is a belligerent

“Rebel,” “insurgent,” and “belligerent” are not interchangeable. Rebellion may describe a Philippine criminal offense, while belligerency normally requires a much more developed factual situation and a legally meaningful act of recognition.

Treating the application of IHL as political recognition

Government forces must respect humanitarian law even when the government considers the armed group unlawful. Compliance protects human beings; it does not concede sovereignty.

Assuming a long-running conflict automatically creates recognition

Duration matters when assessing the intensity of armed violence, but decades of fighting do not by themselves create belligerent status or statehood.

Assuming peace talks create a new government

A group may negotiate, sign a ceasefire, operate a monitoring mechanism, or participate in a peace process without becoming a state or acquiring sovereign authority.

Using “national liberation movement” too broadly

Additional Protocol I uses the concept in a narrow historical and legal setting involving colonial domination, alien occupation, or racist regimes. A movement’s preferred name does not establish the treaty classification.

Assuming humane treatment means immunity

A detainee may be protected from torture and summary execution while still facing lawful investigation and prosecution.

Ignoring obligations of non-state armed groups

International humanitarian law is not directed only at government soldiers. Organized armed groups may also incur obligations, and their leaders and members may face individual criminal responsibility.

Frequently Asked Questions

Are insurgents subjects of international law?

They may have limited international rights and duties, especially when they are organized parties to an armed conflict. This limited personality does not make them states or give them full diplomatic capacity.

What is the main difference between an insurgent and a belligerent?

Insurgency generally describes organized armed resistance. Belligerency is a higher and historically more formal status associated with sustained war-like conflict, territorial control, organized command, and recognition. Modern humanitarian law can apply to insurgents without recognizing belligerency.

Is the New People’s Army automatically a belligerent?

No. The existence of an organized armed group, prolonged hostilities, peace negotiations, or the application of international humanitarian law does not automatically produce recognition of belligerency. RA 9851 expressly states that applying the law does not imply such recognition. (Philippine News Agency)

Does signing a peace agreement make an armed group a state?

No. An armed group may enter a ceasefire, humanitarian agreement, or peace accord without becoming a sovereign state. Any agreement involving changes to Philippine territory, governmental powers, or constitutional structures must remain within the Constitution or follow the proper constitutional process.

Do captured insurgents automatically become prisoners of war?

Not in an ordinary non-international armed conflict. They are entitled to humane treatment and fair judicial guarantees, but they do not automatically receive prisoner-of-war status or immunity from domestic prosecution.

Different rules may apply in a qualifying international armed conflict, including a conflict covered by Article 1(4) of Additional Protocol I.

Can insurgents commit war crimes?

Yes. Members and commanders of non-state armed groups may be prosecuted for serious violations of Common Article 3 and other applicable humanitarian rules. These may include murder, torture, cruel treatment, hostage-taking, attacks against civilians, and sentencing or execution without proper judicial guarantees.

Is a national liberation movement the same as a separatist movement?

No. A separatist movement seeks political separation or independence. A national liberation movement under Additional Protocol I must fit the Protocol’s specific framework involving colonial domination, alien occupation, or racist regimes and the exercise of self-determination.

Who decides whether belligerency has been recognized?

Recognition normally comes from an official act of the territorial state or, historically, from another state addressing the legal consequences of the conflict. Courts may later examine the act and its consequences. News reports, academic opinions, or a group’s own declaration are not sufficient by themselves.

Can a foreign commander be prosecuted in the Philippines under RA 9851?

Potentially, yes. Philippine courts may exercise jurisdiction when the accused is present in the Philippines, when the accused is Filipino, or when the victim is Filipino, subject to the statute’s requirements and applicable procedural rules.
