Applicable Law and Status of Parties
- Full body of IHL applies to IACs, limited set for NIACs
- of Geneva Conventions and Additional Protocol II primary NIAC sources
- Equality of belligerents in IACs grants equal rights and obligations
- Legal status of non-state armed groups in NIACs remains controversial
- Combatant status and POW protections exist in IACs but not NIACs

Key Terms to Review (25)
Accountability: Accountability refers to the obligation of individuals, institutions, and governments to explain and justify their actions and decisions, particularly in relation to human rights. This concept emphasizes the importance of transparency and responsibility in ensuring that human rights are upheld and that violations are addressed, fostering trust within societies.
Additional Protocols: Additional Protocols are treaties that supplement the Geneva Conventions, designed to enhance the protection of victims in armed conflicts and establish clearer rules governing the conduct of hostilities. These protocols aim to address gaps in the original conventions, ensuring that international humanitarian law evolves to respond to modern warfare challenges and provides comprehensive protections for civilians and combatants.
Civilians: Civilians are individuals who are not members of the armed forces or combatants in a conflict. Their protection is a fundamental principle in international humanitarian law, which aims to minimize suffering during armed conflicts. The distinction between civilians and combatants is crucial, as it guides the conduct of hostilities and informs the obligations of parties involved in warfare to protect those who are not participating in the fighting.
Combatants: Combatants are individuals who are legally permitted to participate directly in hostilities during an armed conflict. They are typically members of the armed forces of a party to a conflict and have the right to engage in military actions against enemy forces, distinguishing them from civilians who do not have this right. Understanding the status and protections afforded to combatants is essential for applying international humanitarian law effectively, as it helps clarify the rules of engagement and the responsibilities of warring parties.
Common article 3: Common Article 3 is a provision in the Geneva Conventions that establishes minimum standards for the humane treatment of individuals not taking part in hostilities, including those who are captured or wounded during an armed conflict. It emphasizes the protection of all persons from violence, torture, and inhumane treatment, ensuring respect for their dignity regardless of their status in the conflict. This article forms a cornerstone of International Humanitarian Law, reinforcing the need for humane treatment during both international and non-international conflicts.
Customary ihl: Customary International Humanitarian Law (IHL) refers to the rules of warfare that arise from established practices and norms, which are generally accepted as binding by states, even without written treaties. This form of law is based on the consistent and general practice of states, accompanied by a sense of legal obligation, making it an essential source of international law during armed conflicts. Customary IHL complements treaty law and plays a critical role in ensuring that humanitarian principles are upheld during warfare.
Distinction: Distinction is a fundamental principle of international humanitarian law that requires parties in an armed conflict to differentiate between combatants and non-combatants, as well as military objectives and civilian objects. This principle aims to protect those who are not participating in hostilities, ensuring that any attacks are directed only at legitimate military targets. Upholding this principle is essential for maintaining the humanitarian nature of armed conflict and minimizing civilian suffering.
Geneva Conventions: The Geneva Conventions are a series of international treaties formulated to protect individuals who are not participating in hostilities, including civilians and those who are wounded or shipwrecked during armed conflicts. These treaties establish standards for humanitarian treatment and aim to limit the effects of armed conflict by protecting those who are not part of the fighting and regulating the conduct of combatants.
Grave breaches: Grave breaches refer to serious violations of the laws of war that are defined in the Geneva Conventions and Additional Protocols, which protect individuals who are not participating in hostilities. These violations are of such severity that they warrant prosecution by states or international courts, as they undermine the fundamental principles of humanitarian law and the protection of human rights during armed conflict.
Grotius: Hugo Grotius was a Dutch jurist and philosopher in the early 17th century, often referred to as the 'father of international law.' His groundbreaking work laid the foundation for modern international humanitarian law by arguing for natural rights and the necessity of lawful conduct during war.
Hague Conventions: The Hague Conventions refer to a series of international treaties and agreements developed at the Hague Conference, primarily aimed at regulating the conduct of warfare and protecting the rights of individuals during armed conflict. These conventions established key principles of International Humanitarian Law, addressing issues such as the treatment of prisoners of war, the protection of civilians, and the rules governing the means and methods of warfare, making them foundational texts in the development of humanitarian norms.
Henri Dunant: Henri Dunant was a Swiss social activist and businessman, best known as the founder of the International Committee of the Red Cross (ICRC) and a pioneer of modern humanitarian law. His experiences during the Battle of Solferino in 1859 inspired him to advocate for the protection of wounded soldiers and led to the establishment of the Geneva Convention, which laid the foundation for International Humanitarian Law.
Humanity: Humanity refers to the collective qualities and attributes that characterize human beings, emphasizing the shared moral values, dignity, and rights of individuals. In the context of international humanitarian law, it underlines the essential principles of protecting human life and ensuring humane treatment during armed conflict, regardless of nationality or status. The concept is crucial for promoting compassion, understanding, and respect for all people, especially in situations of war and crisis.
Inhumane treatment: Inhumane treatment refers to actions that cause severe physical or mental suffering, degrading treatment, or violations of personal dignity, particularly in the context of conflict or detention. It is prohibited under international humanitarian law, which seeks to protect individuals who are not participating in hostilities and to limit the effects of armed conflict. Understanding this term is essential as it underscores the necessity for humane treatment and the legal obligations imposed on parties during armed conflicts.
International armed conflicts: International armed conflicts refer to hostilities that occur between two or more states, which involve the use of armed force. These conflicts are governed by international humanitarian law (IHL), specifically the Geneva Conventions, which set out rules aimed at protecting individuals who are not participating in hostilities and regulating the means and methods of warfare.
International Committee of the Red Cross: The International Committee of the Red Cross (ICRC) is a humanitarian organization established to protect the lives and dignity of victims of armed conflict and other situations of violence. It plays a crucial role in the development and enforcement of international humanitarian law, including the Geneva Conventions, while also working to ensure that human rights are respected in times of war and conflict.
International humanitarian law: International humanitarian law (IHL) is a set of rules that aim to limit the effects of armed conflict for humanitarian reasons, protecting individuals who are not participating in hostilities and restricting the means and methods of warfare. It serves to balance military necessity with humanitarian concerns, ensuring that even in times of war, fundamental human rights and dignity are upheld.
Military necessity: Military necessity is a legal doctrine in international humanitarian law that permits measures which are necessary to achieve a legitimate military objective, even if such measures may cause incidental harm to civilians or damage to civilian objects. This concept aims to strike a balance between military objectives and humanitarian considerations during armed conflict, guiding armed forces in their conduct and the limits of permissible actions.
Non-international armed conflicts: Non-international armed conflicts refer to violent confrontations that occur within a single state, involving governmental forces and organized armed groups or between such groups themselves. These conflicts are characterized by their internal nature and can lead to significant humanitarian concerns, triggering specific legal protections under International Humanitarian Law.
Precaution: Precaution refers to the principle of taking proactive measures to prevent harm before it occurs, particularly in situations where there is a risk of significant damage or injury. In the context of humanitarian law, this concept emphasizes the necessity of safeguarding civilians and non-combatants from the dangers arising from military operations, thereby enhancing the protection of human rights during armed conflicts.
Proportionality: Proportionality is a legal and ethical principle that ensures actions taken, especially by states or governing bodies, are appropriate and balanced in relation to their intended goals, particularly in situations involving human rights and humanitarian law. It demands that any interference with rights must be necessary and not excessive, ensuring that measures taken are proportionate to the legitimate aim pursued.
Protected persons: Protected persons are individuals who, in times of armed conflict, are afforded special rights and protections under international humanitarian law, specifically the Geneva Conventions. This term primarily refers to civilians, medical personnel, and aid workers who do not take a direct part in hostilities and are thus entitled to humane treatment and safeguarding from violence and coercion. The legal framework aims to ensure their safety and dignity during conflicts, reflecting the principles of humanity and the need to protect those who cannot defend themselves.
Rome Statute of the International Criminal Court: The Rome Statute of the International Criminal Court is an international treaty that established the International Criminal Court (ICC) in 2002, which aims to prosecute individuals for serious crimes such as genocide, war crimes, and crimes against humanity. This statute represents a significant development in international law by creating a permanent court to hold individuals accountable for heinous acts that threaten global peace and security.
Universal jurisdiction: Universal jurisdiction is a legal principle that allows a national court to prosecute individuals for serious crimes, such as genocide, war crimes, and crimes against humanity, regardless of where the crime was committed or the nationality of the accused or the victims. This principle aims to ensure accountability for egregious violations of human rights and seeks to prevent impunity for perpetrators by enabling states to take action against them, even if they are not connected to the crime by nationality or location.
War crimes: War crimes are serious violations of the laws and customs of war that occur during armed conflicts. They include acts such as intentionally killing civilians, torturing prisoners of war, and using prohibited weapons. Understanding these crimes is crucial for upholding international humanitarian law, ensuring accountability through international criminal law, and addressing atrocities that may fall under the definition of genocide or trigger the Responsibility to Protect doctrine.
