The Application Of International Humanitarian Law To Non-State Armed Groups.

ABSTRACT

The rise of Non-State Armed Groups (NSAGs) in contemporary armed conflicts presents a significant challenge to the application and enforcement of International Humanitarian Law (IHL). Traditionally, IHL has been designed to regulate the conduct of war between sovereign states. However, with the increasing prevalence of asymmetric warfare, internal armed conflicts, and transnational insurgencies, the role of NSAGs in modern conflicts has become more pronounced. The question of whether, how, and to what extent IHL applies to NSAGs remains a critical legal issue.

This paper examines the legal framework governing NSAGs under IHL, including the applicability of Common Article 3 of the Geneva Conventions, Additional Protocol II, and customary IHL rules. While Common Article 3 provides minimum humanitarian protections applicable to non-international armed conflicts (NIACs), its enforcement on NSAGs remains problematic due to their lack of formal recognition under international law. Similarly, Additional Protocol II offers more detailed provisions for conflicts involving NSAGs but applies only when certain conditions—such as control over territory—are met. The paper also explores the role of customary international law in bridging the gaps left by treaty law, ensuring that even NSAGs that are not party to treaties remain bound by fundamental humanitarian obligations.

One of the central challenges in applying IHL to NSAGs is compliance and enforcement. Unlike states, NSAGs do not have permanent institutions or governance structures capable of ensuring adherence to international legal norms. Additionally, states often resist extending legal recognition to NSAGs due to concerns about legitimizing insurgents, rebels, or terrorist groups. This lack of recognition further complicates the ability of international organizations like the International Committee of the Red Cross (ICRC) and the United Nations (UN) to engage with NSAGs for humanitarian purposes. The paper also highlights the tension between state sovereignty and humanitarian imperatives, where governments may view humanitarian engagement with NSAGs as interference in their internal affairs.

To illustrate these challenges, the paper presents case studies of various NSAGs, including the Taliban in Afghanistan, the Revolutionary Armed Forces of Colombia (FARC), ISIS, and Hezbollah. Each case demonstrates different aspects of NSAGs’ interaction with IHL, such as their treatment of civilians, their use of tactics that violate humanitarian norms, and the extent to which they adhere to ceasefire agreements or peace processes. The paper also examines the role of international tribunals, such as the International Criminal Court (ICC), hybrid courts, and UN war crime tribunals, in holding NSAG members accountable for violations of IHL.

Finally, the paper explores potential mechanisms for improving NSAG compliance with IHL, including deeds of commitment, engagement through humanitarian diplomacy, targeted sanctions, and incentives for adherence to IHL norms. It argues for a more pragmatic approach that balances the need to uphold humanitarian principles while recognizing the political realities of armed conflicts involving NSAGs.

This study contributes to the ongoing discourse on the evolving nature of warfare, the legal and ethical dilemmas of regulating NSAGs, and the future of IHL in an increasingly fragmented global security landscape.

Introduction

The nature of modern armed conflicts has evolved significantly over the past century, with a notable shift from traditional inter-state wars to non-international armed conflicts (NIACs) in which Non-State Armed Groups (NSAGs) play a dominant role. These groups, which function outside formal state control, often engage in prolonged insurgencies, terrorist activities, and asymmetric warfare against state militaries or rival factions. The increasing prevalence of NSAGs presents a legal challenge for the application and enforcement of International Humanitarian Law (IHL) since the framework was historically developed with sovereign states in mind.
While this area of law is distinct from Corporate Legal Advisory, both fields demonstrate how evolving global frameworks, shifting power structures, and compliance obligations shape modern legal systems.

NSAGs vary widely in structure, objectives, and levels of organization. Some, like the Revolutionary Armed Forces of Colombia (FARC) and the Taliban, have exercised territorial control and established quasi-governmental institutions. Others, like ISIS (Islamic State) and Al-Qaeda, function as transnational terrorist networks with fluid organizational structures.[1]The legal status of NSAGs and their obligations under IHL remain contested issues in international law, particularly because NSAGs are not formal signatories to international treaties like the Geneva Conventions.[2]Nevertheless, Common Article 3 of the 1949 Geneva Conventions explicitly extends minimum humanitarian protections to conflicts involving NSAGs, obligating all parties—including non-state actors—to uphold fundamental rules of warfare.

The Challenge of Applying IHL to NSAGs

The application of IHL to NSAGs faces several legal and practical challenges. First, states often resist acknowledging NSAGs as legitimate conflict parties due to concerns about granting them political recognition. Second, compliance and enforcement mechanisms are weaker for NSAGs than for states, as these groups lack stable governance structures to ensure adherence to legal norms. Third, while some NSAGs explicitly reject IHL, others selectively comply based on strategic interests, highlighting the lack of a uniform approach to NSAG accountability.

The issue is further complicated by the interaction between IHL and international human rights law (IHRL). Unlike IHL, which primarily applies during armed conflicts, IHRL governs the state’s treatment of individuals at all times. However, as NSAGs increasingly perform quasi-governmental functions—such as administering justice, controlling populations, and enforcing local laws—their accountability under both IHL and IHRL has become a subject of legal debate. Courts and international tribunals, including the International Criminal Court (ICC) and ad hoc tribunals like the ICTY (International Criminal Tribunal for the Former Yugoslavia), have expanded the interpretation of IHL obligations to NSAGs, setting important precedents for war crimes prosecution.

Legal Framework of International Humanitarian Law Applicable to Non-State Armed Groups

The regulation of Non-State Armed Groups (NSAGs) under International Humanitarian Law (IHL) presents a complex and evolving legal challenge. Traditionally, IHL has been designed to govern armed conflicts involving sovereign states, with well-defined obligations under the 1949 Geneva Conventions and their 1977 Additional Protocols. However, the rise of internal armed conflicts, insurgencies, and transnational terrorist organizations has necessitated a reevaluation of the legal obligations of NSAGs. While NSAGs are not formal parties to international treaties, several legal instruments and customary law principles impose obligations upon them, ensuring that basic humanitarian protections apply even in conflicts where non-state actors are involved.

Despite these challenges, several legal frameworks impose obligations on NSAGs, ensuring that fundamental humanitarian principles apply even in conflicts involving non-state actors. This section explores the treaty-based obligations, customary international law (CIL), and jurisprudence from international courts that govern NSAGs and examines the challenges in ensuring their compliance with IHL.

Geneva Conventions

The most fundamental IHL provision applicable to NSAGs is Common Article 3 of the 1949 Geneva Conventions, which applies to all NIACs. It establishes minimum humanitarian protections for persons who do not take direct part in hostilities, including civilians, wounded combatants, and detainees.

Common Article 3 prohibits the following acts:

  1. Murder, torture, and cruel treatment;

  2. Taking of hostages;

  3. Humiliating and degrading treatment;

  4. Passing of sentences without a fair trial.

Although NSAGs are not parties to the Geneva Conventions, Common Article 3 is universally binding and applies irrespective of a group’s formal recognition or political status.

B. Additional Protocol II to the Geneva Conventions (1977)

Recognizing the limitations of Common Article 3, the 1977 Additional Protocol II (AP II) was adopted to expand the legal framework for NIACs. AP II applies when an NSAG:

  1. Exercises territorial control;

  2. Has a responsible command structure.

  3. Is capable of implementing IHL obligations.

AP II provides stronger civilian protections and explicitly prohibits:

  • Indiscriminate attacks on civilians;

  • Reprisals against protected persons;

  • Forced displacement of civilians (except for security reasons);

  • Recruitment of child soldiers.

However, AP II applies only to organized armed groups that meet a specific threshold, which excludes loosely structured insurgencies and terrorist organizations.

 

 

Customary International Humanitarian Law and NSAGs

Even when Non-State Armed Groups (NSAGs) are not formally bound by treaties, they are still subject to Customary International Humanitarian Law (CIL), which consists of long-standing principles recognized as legally binding on all conflict parties.[1]The International Committee of the Red Cross (ICRC) has identified 161 rules of CIL, many of which apply to both states and NSAGs.

Key customary IHL principles applicable to NSAGs include:

  • Distinction – NSAGs must distinguish between combatants and civilians.

  • Proportionality – Attacks that cause excessive civilian harm are prohibited.

  • Humane Treatment – Detainees and civilians must be treated humanely.

  • Prohibition of certain weapons, including chemical and biological weapons.

CIL reinforces IHL obligations on NSAGs, even if they refuse to recognize or sign international treaties.

Jurisprudence and International Court Decisions

A. Prosecutor v. Tadić (ICTY, 1995)

The landmark case Prosecutor v. Tadić before the International Criminal Tribunal for the Former Yugoslavia (ICTY) expanded the interpretation of IHL’s applicability to NSAGs. The ICTY ruled that customary IHL applies to all parties in Non-International Armed Conflicts (NIACs), including NSAGs, reinforcing Common Article 3 and Additional Protocol II (AP II) obligations.

B. The Rome Statute and the International Criminal Court (ICC)

The Rome Statute of the International Criminal Court (ICC) establishes criminal liability for individuals, including NSAG members, who commit war crimes. Article 8 of the Rome Statute criminalizes:

  • Intentional attacks on civilians;

  • Use of child soldiers;

  • Torture and inhumane treatment;

  • Sexual violence as a war crime.

The ICC has prosecuted NSAG leaders, including the conviction of Thomas Lubanga, leader of the Union of Congolese Patriots, for child soldier recruitment.

 

 Challenges in Enforcing IHL Against NSAGs

Despite the existence of a clear legal framework, enforcing IHL against NSAGs presents significant challenges, including:

  • Lack of Treaty Ratification – NSAGs are not formal parties to international treaties.[1]

  • Weak Compliance Mechanisms – Unlike states, NSAGs lack structured enforcement institutions.

  • Political Reluctance – Governments often refuse to recognize NSAGs as legitimate conflict parties.

  • Fragmentation Within NSAGs – Internal divisions hinder adherence to IHL commitments.

 

Challenges in Enforcing International Humanitarian Law Against Non-State Armed Groups

The enforcement of International Humanitarian Law (IHL) against Non-State Armed Groups (NSAGs) presents significant legal, political, and practical challenges. Although NSAGs are bound by Common Article 3 of the Geneva Conventions, Additional Protocol II (AP II), and Customary International Humanitarian Law (CIL), ensuring compliance and accountability remains a major difficulty.[1] Unlike states, NSAGs lack formal treaty obligations, structured enforcement mechanisms, and political recognition, which complicates the enforcement of IHL.

This section examines the key challenges in enforcing IHL against NSAGs, including:

  1. Lack of Treaty Ratification
  2. Weak Compliance Mechanisms
  3. Political Reluctance and State Sovereignty Issues
  4. Fragmentation and Lack of Centralized Authority
  5. Limited Access to Accountability Mechanisms
  6. Humanitarian Engagement Constraints

 

A. Lack of Treaty Ratification

One of the primary challenges in enforcing IHL against NSAGs is their inability to ratify international treaties. Treaties such as the Geneva Conventions (1949), Additional Protocols (1977), and the Rome Statute (1998) are only binding on states. Since NSAGs do not have statehood, they cannot become formal parties to these treaties, even though they operate within the framework of armed conflicts.

However, some legal mechanisms attempt to extend IHL obligations to NSAGs:

  • Common Article 3 of the Geneva Conventions explicitly applies to all parties in a non-international armed conflict, including NSAGs.
  • AP II further establishes rules for NSAGs that exercise territorial control, but it applies only if the state concerned has ratified AP II.
  • Customary International Humanitarian Law (CIL) applies to all conflict actors, including NSAGs, but its enforcement is inconsistent.

B. Weak Compliance Mechanisms

Even when NSAGs are deemed bound by IHL, ensuring compliance remains difficult due to a lack of structured enforcement mechanisms. Unlike states, which have judicial, military, and administrative institutions to ensure adherence, NSAGs often operate without internal legal frameworks.

Some factors contributing to weak compliance include:

  • Absence of Military Discipline – Unlike regular state armies, many NSAGs lack centralized command structures that enforce IHL norms.
  • Lack of Training and Awareness – NSAG members often do not receive formal training in IHL, leading to violations out of ignorance.
  • Pragmatic Over Ideological Compliance – Many NSAGs follow IHL only when it aligns with their strategic interests, rather than due to legal obligations.

C. Political Reluctance and State Sovereignty Issues

States often refuse to acknowledge NSAGs as legitimate conflict parties, fearing that doing so may grant them political legitimacy. This reluctance hinders IHL engagement efforts and peace negotiations.

Key political challenges include:

  • Criminalization of NSAGs – Many governments classify NSAGs as terrorist organizations, making it difficult to negotiate compliance with IHL.
  • State Denial of Internal Conflicts – Some states refuse to acknowledge the existence of a Non-International Armed Conflict (NIAC) to avoid legal responsibilities under Common Article 3 and AP II.
  • Use of Military Force Over Legal Compliance – Governments often prioritize military suppression over legal accountability, reducing incentives for NSAGs to follow IHL.

D. Fragmentation and Lack of Centralized Authority

Many NSAGs lack unified leadership, making it difficult to enforce compliance within their ranks. Armed groups often experience:

  • Internal Factionalism – Rival factions within NSAGs may have conflicting policies on IHL compliance.
  • Breakaway Splinter Groups – If a faction disagrees with peace processes, it may split from the main NSAG and continue hostilities.
  • Multiple Chains of Command – In some conflicts, NSAGs operate as loosely affiliated networks rather than hierarchical organizations, leading to inconsistent adherence to IHL.

E. Limited Access to Accountability Mechanisms

Even when NSAGs commit grave breaches of IHL, prosecuting them under international law remains difficult due to:

  • Lack of Jurisdiction – International tribunals such as the International Criminal Court (ICC) focus primarily on individual criminal responsibility, making it harder to prosecute NSAGs as entities.
  • State Protection of NSAGs – In some conflicts, states provide covert support to NSAGs, shielding them from legal accountability.
  • Challenges in Evidence Collection – Investigating war crimes by NSAGs is challenging due to restricted access to conflict zones.

F. Humanitarian Engagement Constraints

Despite efforts by organizations like the International Committee of the Red Cross (ICRC) and Geneva Call, engaging NSAGs in humanitarian dialogue remains difficult due to:

  • Security Risks – Many humanitarian agencies face threats from hostile NSAG factions.
  • Legal Barriers – Some states criminalize interactions with NSAGs, preventing NGOs from promoting IHL compliance.
  • Lack of Trust – NSAGs often view humanitarian organizations with suspicion, believing them to be aligned with state interests.

Case Studies on the Application of International Humanitarian Law to Non-State Armed Groups

The application of International Humanitarian Law (IHL) to Non-State Armed Groups (NSAGs) is an evolving legal issue, particularly in non-international armed conflicts (NIACs). While IHL binds all conflict parties, ensuring compliance by NSAGs remains challenging.[2] Various case studies highlight the complexities surrounding NSAGs’ obligations, their violations, and efforts to enforce accountability. This section examines four significant case studies where NSAGs were scrutinized under IHL:

  1. Prosecutor v. Tadić (ICTY, 1995) – Establishing the applicability of IHL to NSAGs.
  2. The Rome Statute and the Prosecution of NSAG Leaders – Examining individual criminal responsibility.
  3. The FARC in Colombia – A case study on peace negotiations and IHL obligations.
  4. The Taliban and IHL Violations in Afghanistan – Analysing compliance and accountability issues.

A. Prosecutor v. Tadić (ICTY, 1995) – Establishing the Applicability of IHL to NSAGs

One of the landmark cases in international criminal law, Prosecutor v. Tadić was adjudicated by the International Criminal Tribunal for Former Yugoslavia (ICTY). The case expanded the interpretation of IHL’s applicability to NSAGs, emphasizing that customary IHL binds all conflict parties, including non-state actors.

The case arose from ethnic violence in Bosnia and Herzegovina (1992–1995), where Dusko Tadić, a Bosnian Serb paramilitary leader, was prosecuted for war crimes, including torture, inhumane treatment, and unlawful confinement. The ICTY established that non-international armed conflicts (NIACs) are governed by customary IHL, reinforcing the binding nature of Common Article 3 and Additional Protocol II (AP II) on NSAGs.

Key Takeaways

  • The ruling confirmed that NSAGs are subject to IHL, regardless of treaty ratification.
  • It reinforced that serious violations of IHL by NSAG members could lead to individual criminal responsibility.
  • It clarified the distinction between internal disturbances and armed conflicts, setting precedents for future cases involving NSAGs.

The Tadić case remains foundational in international law, demonstrating that NSAGs cannot evade IHL obligations, even if they are not formal treaty signatories.

B. The Rome Statute and the Prosecution of NSAG Leaders

The Rome Statute (1998) established the International Criminal Court (ICC), which prosecutes war crimes, crimes against humanity, and genocide, including those committed by NSAGs. While states are directly bound by the treaty, the ICC has held individual NSAG leaders accountable for grave IHL violations[3].

A notable example is the prosecution of Thomas Lubanga Dyilo, leader of the Union of Congolese Patriots (UPC), for recruiting and using child soldiers in the Democratic Republic of the Congo (DRC). The Lubanga case (2012) was the first ICC conviction for war crimes committed by an NSAG leader.

Key Takeaways

  • The case confirmed that NSAG commanders can be held criminally responsible for IHL violations.
  • It set legal precedents for the prosecution of child soldier recruitment as a war crime.
  • The ICC’s jurisdiction over NSAGs remains limited, as it relies on state cooperation for enforcement.

The prosecution of Lubanga and other NSAG leaders, such as Joseph Kony (Lord’s Resistance Army), has reinforced the individual criminal liability of NSAG members under IHL and international criminal law.

C. The FARC in Colombia – A Case Study on Peace Negotiations and IHL Obligations

The Revolutionary Armed Forces of Colombia (FARC) provides a compelling example of an NSAG engaged in both armed conflict and peace negotiations. The FARC, one of Latin America’s longest-running insurgencies, was involved in a five-decade-long armed conflict with the Colombian government, committing grave IHL violations, including hostage-taking, forced recruitment, and attacks on civilians.

Despite being designated as a terrorist organization, the FARC engaged in peace talks, leading to the 2016 Peace Agreement with the Colombian government[4]. A critical aspect of the peace process was the accountability of FARC members for war crimes[5]. The Special Jurisdiction for Peace (JEP) was established to investigate and prosecute serious IHL violations, ensuring justice for victims while facilitating NSAG reintegration into society.

Key Takeaways

  • The FARC case demonstrates that peace negotiations can incorporate IHL accountability mechanisms.
  • The JEP’s restorative justice model has been a controversial yet innovative approach to prosecuting NSAG members.
  • The case highlights the role of transitional justice in ensuring NSAGs comply with IHL in post-conflict scenarios.

The FARC’s transition from an armed insurgency to a political movement underscores the complex relationship between NSAGs, IHL enforcement, and peacebuilding efforts.

D. The Taliban and IHL Violations in Afghanistan

The Taliban, an NSAG turned de facto government in Afghanistan (2021), presents one of the most complex cases concerning IHL compliance. Since its emergence in the 1990s, the Taliban has been accused of numerous IHL violations, including targeting civilians, extrajudicial killings, and using human shields.

During the U.S.-led war in Afghanistan (2001–2021), the Taliban engaged in asymmetric warfare, often blurring the distinction between combatants and civilians. The Taliban’s use of suicide bombings, targeted assassinations, and attacks on humanitarian workers raised serious concerns under Common Article 3 and AP II.

Key Takeaways

  • The Taliban’s IHL violations illustrate the difficulty in enforcing international norms against NSAGs in asymmetric warfare.
  • The 2020 U.S.-Taliban Agreement raised questions about whether diplomatic negotiations can improve NSAG compliance with IHL.
  • The Taliban’s return to power in 2021 has renewed concerns about the enforcement of humanitarian norms under NSAG governance.

The Taliban’s evolving status—from NSAG to governing entity—raises broader questions about whether NSAGs should be treated differently when they control territory and act as de facto authorities.

Mechanisms to Strengthen Compliance with International Humanitarian Law by Non-State Armed Groups

Ensuring compliance with International Humanitarian Law (IHL) by Non-State Armed Groups (NSAGs) remains one of the most significant challenges in contemporary armed conflicts. While states are bound by international treaties and customary international law[6], NSAGs often operate outside formal legal structures, making enforcement difficult. Strengthening compliance mechanisms requires a multifaceted approach, including legal accountability, humanitarian engagement, incentive-based compliance strategies, and improved enforcement mechanisms.

This section explores various mechanisms to strengthen NSAG compliance with IHL, focusing on:

  1. Legal Accountability through International and Domestic Courts
  2. Engagement with NSAGs for Voluntary Compliance
  3. Monitoring and Reporting Mechanisms
  4. Humanitarian Dialogue and Special Agreements
  5. The Role of the United Nations and Regional Organizations
  6. Economic and Political Incentives for Compliance

A. Legal Accountability through International and Domestic Courts

One of the most direct mechanisms for enforcing IHL is legal accountability. Several international courts and domestic legal frameworks aim to hold NSAG members responsible for war crimes, crimes against humanity, and genocide.

1. The Role of the International Criminal Court (ICC)

The Rome Statute of the International Criminal Court (ICC)[7] provides a legal framework to prosecute individuals, including NSAG members, who commit grave violations of IHL. Cases such as Prosecutor v. Thomas Lubanga Dyilo have demonstrated the ICC’s ability to convict NSAG leaders for crimes like child soldier recruitment. However, the ICC’s enforcement power remains limited, as it relies on state cooperation to arrest and prosecute offenders.

2. Domestic Prosecution Under Universal Jurisdiction

Some states exercise universal jurisdiction to prosecute NSAG members for war crimes committed outside their territory. Countries like Germany and Spain have initiated cases against foreign NSAG fighters based on the principle that certain IHL violations, such as torture and genocide, are crimes against all humanity.[8]

3. Hybrid Tribunals and Special Courts

Hybrid courts, such as the Special Court for Sierra Leone (SCSL) and the Extraordinary Chambers in the Courts of Cambodia (ECCC), have successfully prosecuted NSAG members for war crimes. Establishing context-specific hybrid tribunals can enhance accountability while ensuring greater local legitimacy.

B. Engagement with NSAGs for Voluntary Compliance

Since legal enforcement is often difficult, engaging directly with NSAGs to promote voluntary compliance with IHL has proven effective.

1. Geneva Call and Declarations of Commitment

Geneva Call, a humanitarian organization, has successfully negotiated Deeds of Commitment with NSAGs, persuading them to abide by IHL norms, such as:

  • Banning child soldier recruitment
  • Prohibiting landmines
  • Protecting civilian populations

Several NSAGs, including groups in Myanmar, Sudan, and Colombia, have signed these agreements, showing that engagement strategies can influence NSAG behaviour.

2. The Role of the International Committee of the Red Cross (ICRC)

The ICRC plays a critical role in training NSAG fighters on IHL, promoting awareness, and engaging them in humanitarian dialogue. Field manuals, workshops, and negotiations help NSAGs understand their legal obligations under IHL.

C. Monitoring and Reporting Mechanisms

Publicly exposing IHL violations can increase pressure on NSAGs to comply with international norms.

1. United Nations Monitoring Mechanisms

The UN Security Council regularly monitors and reports grave violations committed by NSAGs, particularly regarding:

  • The recruitment and use of child soldiers
  • Sexual violence in conflict
  • Attacks on humanitarian personnel

The Secretary-General’s annual report on children and armed conflict has led to sanctions and public condemnations against groups like Al-Shabaab, Boko Haram, and the Taliban[9].

2. Independent Human Rights Organizations

Groups like Human Rights Watch, Amnesty International, and the UN Human Rights Council document NSAG abuses, providing critical evidence for international prosecutions and advocacy efforts.

D. Humanitarian Dialogue and Special Agreements

1. Common Article 3 and Special Agreements Under Additional Protocol II

Common Article 3 of the Geneva Conventions encourages NSAGs and states to enter special agreements, which formalize IHL obligations. The 2016 peace agreement between the Colombian Government and FARC is an example of how special agreements can lead to greater IHL compliance.

2. Negotiations with NSAGs During Armed Conflicts

The ICRC and other neutral actors facilitate conflict mediation, ensuring that NSAGs commit to protecting civilians, allowing humanitarian access, and ceasing indiscriminate attacks.

E. The Role of the United Nations and Regional Organizations

1. UN Peacekeeping Missions

UN peacekeeping forces monitor IHL compliance by NSAGs and provide humanitarian protection in conflict zones. The UN’s presence in South Sudan, the Central African Republic, and the Democratic Republic of the Congo has contributed to reducing IHL violations by NSAGs.

2. Sanctions by the UN and Regional Organizations

Targeted economic and travel sanctions against NSAG leaders have been used to deter war crimes and human rights abuses. The African Union and European Union have also imposed restrictive measures on NSAGs involved in grave IHL violations.

F. Economic and Political Incentives for Compliance

Providing incentives for NSAGs to follow IHL can improve compliance rates.

1. Amnesty and Reintegration Programs

Offering conditional amnesty to NSAG fighters who demobilize and comply with IHL has been successful in countries like Sierra Leone, Colombia, and Nepal. Transitional justice mechanisms balance accountability with peacebuilding efforts.

2. Recognition in Peace Negotiations

Governments that recognize NSAGs as legitimate negotiating parties create incentives for compliance. The Moro Islamic Liberation Front (MILF) in the Philippines agreed to uphold IHL standards during peace talks, leading to greater protection of civilians.

Conclusions and Recommendations

The role of Non-State Armed Groups (NSAGs) in contemporary armed conflicts has significantly reshaped the landscape of International Humanitarian Law (IHL). While NSAGs are often perceived as unregulated actors operating outside the scope of international law, the legal framework governing their conduct has evolved to impose clear obligations under Common Article 3 of the Geneva Conventions, Additional Protocol II (AP II), Customary International Humanitarian Law (CIL), and international court decisions. Despite these legal provisions, enforcing IHL against NSAGs remains a major challenge due to lack of treaty ratification, weak compliance mechanisms, political reluctance, and fragmentation within NSAG structures.

Just as evolving Business Law frameworks guide corporate responsibility and regulatory compliance, strengthening IHL enforcement mechanisms is essential for ensuring accountability and lawful conduct among conflict actors

The jurisprudence of international criminal tribunals, including the International Criminal Tribunal for the Former Yugoslavia (ICTY) and the International Criminal Court (ICC), has further reinforced the accountability of NSAGs for war crimes, crimes against humanity, and other serious violations of IHL. However, enforcement gaps continue to exist due to political constraints, logistical challenges, and the reluctance of states to recognize NSAGs as legitimate parties to a conflict.

To ensure better compliance with IHL by NSAGs, it is necessary to adopt a comprehensive approach that goes beyond legal enforcement. Mechanisms such as direct engagement, monitoring and reporting, humanitarian dialogue, economic incentives, and transitional justice frameworks have proven to be effective in influencing NSAG behaviour. The involvement of international organizations like the International Committee of the Red Cross (ICRC), Geneva Call, and the United Nations (UN) has played a crucial role in promoting IHL awareness and fostering voluntary compliance among NSAGs.

Ultimately, while progress has been made in developing legal and practical mechanisms to regulate NSAGs, there is a pressing need to strengthen enforcement mechanisms, enhance accountability measures, and expand engagement strategies to ensure greater protection of civilians and adherence to IHL principles in non-international armed conflicts (NIACs).
