The Geneva Conventions are international humanitarian laws consisting of four treaties and three additional protocols that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention colloquially denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel; establish protections for the wounded and sick; and provide protections for the civilians in and around a war-zone. [2]
The Geneva Conventions define the rights and protections afforded to those non-combatants who fulfill the criteria of being protected persons . [3] The treaties of 1949 were ratified, in their entirety or with reservations, by 196 countries. [4] The Geneva Conventions concern only protected non-combatants in war. The use of wartime conventional weapons is addressed by the Hague Conventions of 1899 and 1907 and the 1980 Convention on Certain Conventional Weapons, while the biological and chemical warfare in international armed conflicts is addressed by the 1925 Geneva Protocol.
The Swiss businessman Henry Dunant went to visit wounded soldiers after the Battle of Solferino in 1859. He was shocked by the lack of facilities, personnel, and medical aid available to help these soldiers. As a result, he published his book, A Memory of Solferino , in 1862, on the horrors of war. [5] His wartime experiences inspired Dunant to propose:
The former proposal led to the establishment of the Red Cross in Geneva. The latter led to the 1864 Geneva Convention, the first codified international treaty that covered the sick and wounded soldiers on the battlefield. On 22 August 1864, the Swiss government invited the governments of all European countries, as well as the United States, Brazil, and Mexico, to attend an official diplomatic conference. Sixteen countries sent a total of twenty-six delegates to Geneva. On 22 August 1864, the conference adopted the first Geneva Convention "for the Amelioration of the Condition of the Wounded in Armies in the Field". Representatives of 12 states and kingdoms signed the convention: [6] [7]
For both of these accomplishments, Henry Dunant became co recipient of the first Nobel Peace Prize in 1901. [8] [9]
On 20 October 1868 the first unsuccessful attempt to expand the 1864 treaty was undertaken. With the 'Additional Articles relating to the Condition of the Wounded in War' an attempt was initiated to clarify some rules of the 1864 convention and to extend them to maritime warfare. The Articles were signed but were only ratified by the Netherlands and the United States of America. [10] The Netherlands later withdrew their ratification. [11] The protection of the victims of maritime warfare would later be realized by the third Hague Convention of 1899 and the tenth Hague Convention of 1907. [12]
In 1906 thirty-five states attended a conference convened by the Swiss government. On 6 July 1906 it resulted in the adoption of the "Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field", which improved and supplemented, for the first time, the 1864 convention. [13] It remained in force until 1970 when Costa Rica acceded to the 1949 Geneva Conventions. [14]
The 1929 conference yielded two conventions that were signed on 27 July 1929. One, the "Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field", was the third version to replace the original convention of 1864. [12] [15] The other was adopted after experiences in World War I had shown the deficiencies in the protection of prisoners of war under the Hague Conventions of 1899 and 1907. The "Convention relative to the Treatment of Prisoners of War" was not to replace these earlier conventions signed at The Hague; rather it supplemented them. [16] [17]
There was considerable debate over whether the Geneva Convention should prohibit indiscriminate forms of warfare, such as aerial bombings, nuclear bombings and starvation, but no agreement was reached on those forms of violence. [18]
Inspired by the wave of humanitarian and pacifistic enthusiasm following World War II and the outrage towards the war crimes disclosed by the Nuremberg and Tokyo trials, a series of conferences were held in 1949 reaffirming, expanding and updating the prior Geneva and Hague Conventions. It yielded four distinct conventions:
Despite the length of these documents, they were found over time to be incomplete. The nature of armed conflicts had changed with the beginning of the Cold War era, leading many to believe that the 1949 Geneva Conventions were addressing a largely extinct reality: [23] on the one hand, most armed conflicts had become internal, or civil wars, while on the other, most wars had become increasingly asymmetric. Modern armed conflicts were inflicting an increasingly higher toll on civilians, which brought the need to provide civilian persons and objects with tangible protections in time of combat, bringing a much needed update to the Hague Conventions of 1899 and 1907.
In light of these developments, two Protocols were adopted in 1977 that extended the terms of the 1949 Conventions with additional protections. In 2005, a third brief Protocol was added establishing an additional protective sign for medical services, the Red Crystal, as an alternative to the ubiquitous Red Cross and Red Crescent emblems, for those countries that find them objectionable.
The Geneva Conventions of 12 August 1949. Commentary (The Commentaries) is a series of four volumes of books published between 1952 and 1958 and containing commentaries to each of the four Geneva Conventions. The series was edited by Jean Pictet who was the vice-president of the International Committee of the Red Cross. The Commentaries are often relied upon to provide authoritative interpretation of the articles. [24]

The Geneva Conventions are rules that apply only in times of armed conflict and seek to protect people who are not or are no longer taking part in hostilities.
The first convention dealt with the treatment of wounded and sick armed forces in the field. [25] The second convention dealt with the sick, wounded, and shipwrecked members of armed forces at sea. [26] [27] The third convention dealt with the treatment of prisoners of war during times of conflict. [28] The fourth convention dealt with the treatment of civilians and their protection during wartime. [29]
Individuals who fulfill the criteria of protected persons in international armed conflicts are protected by the 1949 conventions. Those not listed as protected persons in such conflicts are instead protected by international human rights law and general treaties concerning the legal status of aliens in belligerent nations. [3]
In international law and diplomacy the term convention refers to an international agreement, or treaty.
With two Geneva Conventions revised and adopted and two added in 1949, the whole is referred to as the "Geneva Conventions of 1949" or simply the "Geneva Conventions". Usually only the Geneva Conventions of 1949 are referred to as First, Second, Third or Fourth Geneva Conventions. The treaties of 1949 were ratified, in whole or with reservations, by 196 countries. [4]
The 1949 conventions have been modified with three amendment protocols:
The Geneva Conventions apply at times of war and armed conflict to governments who have ratified its terms. The details of applicability are spelled out in Common Articles 2 and 3.
This article states that the Geneva Conventions apply to all the cases of international armed conflict (IAC), where at least one of the warring nations has ratified the Conventions. Primarily:
Article 1 of Protocol I further clarifies that armed conflict against colonial domination and foreign occupation also qualifies as an international conflict.
When the criteria of international armed conflict have been met, the full protections of the Conventions are considered to apply.
This article states that the certain minimum rules of war apply to armed conflicts "not of an international character." [41] The International Committee of the Red Cross has explained that this language describes non-international armed conflict (NIAC) "where at least one Party is not a State." [42] For example, it would apply to conflicts between state forces and non-state actors (NSAs), or between two NSAs, or to other conflicts that have all the characteristics of war, whether carried out within the confines of one country or not. [43]
There are two criteria to distinguish non-international armed conflicts from lower forms of violence. The level of violence has to be of certain intensity, for example when the state cannot contain the situation with regular police forces. Also, involved non-state groups need to have a certain level of organization, like a military command structure. [44]
The other Geneva Conventions are not applicable in this situation but only the provisions contained within Article 3, [27] and additionally within the language of Protocol II. The rationale for the limitation is to avoid conflict with the rights of Sovereign States that were not part of the treaties. When the provisions of this article apply, it states that: [45]
Persons taking no active part in the hostilities, including members of armed forces who have laid down their arms and those placed hors de combat by sickness, wounds, detention, or any other cause, shall in all circumstances be treated humanely, without any adverse distinction founded on race, colour, religion or faith, sex, birth or wealth, or any other similar criteria. To this end, the following acts are and shall remain prohibited at any time and in any place whatsoever with respect to the above-mentioned persons:
- violence to life and person, in particular murder of all kinds, mutilation, cruel treatment and torture;
- taking of hostages;
- outrages upon dignity, in particular humiliating and degrading treatment; and
- the passing of sentences and the carrying out of executions without previous judgment pronounced by a regularly constituted court, affording all the judicial guarantees which are recognized as indispensable by civilized peoples.
- The wounded and sick shall be collected and cared for.
During the negotiation of the Geneva Conventions, France and Britain were initially staunchly opposed to Common Article 3. However, to save face during negotiations and make strategic concessions, France and Britain deliberately introduced ambiguous language in the text of Common Article 3 that made it easy for states to avoid the obligations of the rule. [46] As a consequence, Common Article 3 only concerns with humane treatment and does not deal with methods and means of hostilities, [47] such as bombings committed by non-state armed groups or state forces against civilian targets in the Algerian War and the Troubles.
On February 7, 2002, President Bush adopted the view that Common Article 3 did not protect al Qaeda prisoners because the United States-al Qaeda conflict was "not of an international character." [48] The Supreme Court of the United States invalidated the Bush Administration view of Common Article 3, in Hamdan v. Rumsfeld , by ruling that Common Article Three of the Geneva Conventions applies to detainees in the "War on Terror", and that the Guantanamo military commission process used to try these suspects was in violation of U.S. and international law. [49] In response to Hamdan, Congress passed the Military Commissions Act of 2006, which President Bush signed into law on October 17, 2006. Like the Military Commissions Act of 2006, its successor the Military Commissions Act of 2009 explicitly forbids the invocation of the Geneva Conventions "as a basis for a private right of action." [50]
"... Common Article 3 continues the conventional practice (reflected in both the 'Lieber' and 'The Hague' provisions) of according humanitarian protections only to 'belligerents' who defer to the laws and customs of war: not to 'insurrectionists' who defy these norms from the very outset of hostilities. Observance of the rules of warfare is what elevates an 'insurrectionist' to the legally cognizable status of 'belligerent' under the 'International law of war'; nothing short of such an 'observance' suffices to effect this transformation from the infra legal to legal." [51] [ self-published source ]
Whether the conflict is an IAC or a NIAC or both depends on the nature and circumstances of the situation. Since there is a general prohibition against the use of force between States (as is reflected within article 2(4) of the United Nations Charter) with respect to Common Article 2, it is generally presumed that any use of such military force which is governed by international humanitarian law (IHL) is attributable to deliberate belligerent intent. [52]
Regarding Common Article 3, the ICRC in its 2016 commentary stated the provision includes not just a conflict between territorial government forces and NSAs or NSAs themselves, but also a foreign military intervention against a NSA only if the territorial state consents to such intervention in its territory. Should the intervening country do so without the consent of the territorial state or in support of a NSA against that state, then Common Article 2 applies. [52] [53]
For example, the American-led intervention in the Syrian civil war became both an IAC with Syria and a NIAC with the Islamic State because the U.S. intervened in Syrian territory without the former's consent. [53] On the other hand, Russia intervened in Syrian territory against the Free Syrian Army upon invitation by Syria, making Russia's participation subject only to Common Article 3 and therefore Protocol II (which Russia ratified on September 29, 1989). [52] [54]
The U.S.-led NATO invasion of Afghanistan from October 7 to December 17, 2001 was initially an IAC because it waged war against the Islamic Emirate of Afghanistan under Taliban rule. Once the new Karzai administration was established and recognized internationally, the conflict changed from an IAC to a NIAC, with NATO troops under International Security Assistance Force (ISAF) and Resolute Support Mission (RSM) auspices assisting the Islamic Republic of Afghanistan with its consent in battling Taliban insurgents. [52] In contrast, the Soviet–Afghan War was an IAC because the Soviet Union invaded the Democratic Republic of Afghanistan (DRA) to remove Afghan communist leader Hafizullah Amin from power, then installed puppet leader Babrak Karmal, who "invited" Soviet troops to intervene against the Afghan mujahideen fighters. [55]
While non-state armed groups are automatically presumed to engage in NIACs, they also can cross into the threshold of an IAC. The 2020 ICRC commentary on the Third Geneva Convention requires two elements for this classification: "the group must in fact fight on behalf of that Party" and "that Party must accept both the fighting role of the group and the fact that the fighting is done on its behalf." It further states that "[w]here a Party to a conflict has overall control over the militia, volunteer corps or organized resistance movement that has a fighting function and fights on the State's behalf, a relationship of belonging for the purposes of Article 4A(2) [56] exists." [57] For example, the Viet Cong was under effective control and direction by North Vietnam during the Vietnam War, therefore Common Article 2 solely applied to the conflict. [58] [59]
The term protecting power has a specific meaning under these Conventions. A protecting power is a state that is not taking part in the armed conflict, but that has agreed to look after the interests of a state that is a party to the conflict. The protecting power is a mediator enabling the flow of communication between the parties to the conflict. The protecting power also monitors the implementation of these Conventions, such as by visiting the zone of conflict and prisoners of war. The protecting power must act as an advocate for prisoners, the wounded, and civilians.
Not all violations of the treaty are treated equally. The most serious crimes are termed grave breaches and provide a legal definition of a war crime. Grave breaches of the Third and Fourth Geneva Conventions include the following acts if committed against a person specifically protected by the conventions: [60]
Also considered grave breaches of the Fourth Geneva Convention are the following: [60]
Nations that are party to these treaties must enact and enforce legislation penalizing any of these crimes. Nations are also obligated to search for persons alleged to commit these crimes, or persons having ordered them to be committed, and to bring them to trial regardless of their nationality and regardless of the place where the crimes took place. [61]
The principle of universal jurisdiction also applies to the enforcement of grave breaches when the United Nations Security Council asserts its authority and jurisdiction from the UN Charter to apply universal jurisdiction. The UNSC did this when they established the International Criminal Tribunal for Rwanda and the International Criminal Tribunal for the former Yugoslavia to investigate and/or prosecute alleged violations.
Soldiers, as prisoners of war, will not receive a trial unless the allegation of a war crime has been made. According to article 43 of the 1949 Conventions, soldiers are employed for the purpose of serving in war; engaging in armed conflict is legitimate, and does not constitute a grave breach. [62] Should a soldier be arrested by belligerent forces, they are to be considered "lawful combatants" and afforded the protectorate status of a prisoner of war (POW) until the cessation of the conflict. [63] Human rights law applies to any incarcerated individual, including the right to a fair trial. [64]
Charges may only be brought against an enemy POW after a fair trial, but the initial crime being accused must be an explicit violation of the accords, more severe than simply fighting against the captor in battle. [64] No trial will otherwise be afforded to a captured soldier, as deemed by human rights law. This element of the convention has been confused during past incidents of detainment of US soldiers by North Vietnam, where the regime attempted to try all imprisoned soldiers in court for committing grave breaches, on the incorrect assumption that their sole existence as enemies of the state violated international law. [64]
Although warfare has changed dramatically since the Geneva Conventions of 1949, they are still considered the cornerstone of contemporary international humanitarian law. [65] They protect combatants who find themselves hors de combat, and they protect civilians caught up in the zone of war. These treaties came into play for all recent non-international armed conflicts, including the War in Afghanistan, [66] the Iraq War, the invasion of Chechnya (1994–2017), [67] and the Russo-Georgian War. The Geneva Conventions also protect those affected by non-international armed conflicts such as the Syrian civil war.[ dubious – discuss ]
The lines between combatants and civilians have blurred when the actors are not exclusively High Contracting Parties (HCP). [68] Since the fall of the Soviet Union, an HCP often is faced with a non-state actor, [69] as argued by General Wesley Clark in 2007. [70] Examples of such conflict include the Sri Lankan Civil War, the Sudanese Civil War, and the Colombian Armed Conflict, as well as most military engagements of the US since 2000.
Some scholars hold that Common Article 3 deals with these situations, supplemented by Protocol II (1977).[ dubious – discuss ] These set out minimum legal standards that must be followed for internal conflicts. International tribunals, particularly the International Criminal Tribunal for the former Yugoslavia (ICTY), have clarified international law in this area. [71] In the 1999 Prosecutor v. Dusko Tadic judgement, the ICTY ruled that grave breaches apply not only to international conflicts, but also to internal armed conflict.[ dubious – discuss ] Further, those provisions are considered customary international law.
Controversy has arisen over the US designation of irregular opponents as "unlawful enemy combatants" (see also unlawful combatant), especially in the Supreme Court of the United States judgments over the Guantanamo Bay detention camp brig facility Hamdi v. Rumsfeld , Hamdan v. Rumsfeld and Rasul v. Bush , [72] and later Boumediene v. Bush . President George W. Bush, aided by Attorneys-General John Ashcroft and Alberto Gonzales and General Keith B. Alexander, claimed the power, as Commander in Chief of the Armed Forces, to determine that any person, including an American citizen, who is suspected of being a member, agent, or associate of Al Qaeda, the Taliban, or possibly any other terrorist organization, is an "enemy combatant" who can be detained in U.S. military custody until hostilities end, pursuant to the international law of war. [73] [74] [75]
The application of the Geneva Conventions in the Russo-Ukrainian War (2014–present) has been troublesome[ vague ] because some of the personnel who engaged in combat against the Ukrainians were not identified by insignia, although they did wear military-style fatigues. [76] The types of comportment qualified as acts of perfidy under jus in bello doctrine are listed in Articles 37 through 39 of the Geneva Convention; the prohibition of fake insignia is listed at Article 39.2, but the law is silent on the complete absence of insignia. The status of POWs captured in this circumstance remains a question.
Educational institutions and organizations including Harvard University, [77] [78] the International Committee of the Red Cross, [79] and the Rohr Jewish Learning Institute use the Geneva Convention as a primary text investigating torture and warfare. [80]
Artificial intelligence and autonomous weapon systems, such as military robots and cyber-weapons, are creating challenges in the creation, interpretation and application of the laws of armed conflict. The complexity of these new challenges, as well as the speed in which they are developed, complicates the application of the Conventions, which have not been updated in a long time. [81] [82] Adding to this challenge is the very slow speed of the procedure of developing new treaties to deal with new forms of warfare, and determining agreed-upon interpretations to existing ones, meaning that by the time a decision can be made, armed conflict may have already evolved in a way that makes the changes obsolete.
In a speech given at the Graduate Institute of International and Development Studies in 13 March 2019, International Committee of the Red Cross President Peter Maurer argued that the "collective challenge [for the ICRC] today is to find ways to ensure greater respect within the changing dynamics of conflict." This would involve "more tailor-made rules to protect civilians from conflict’s future front lines" regarding issues such as "armed actors and civilians intermingling and individuals changing from fighters at night to civilians by day; different forms of violence blending together, on increasingly fuzzy battlefields," as well as “fierce public defence” of any new suggested rules. [83]
Tilman Rodenhäuser and Mauro Vignati, advisors on legal issues and digital technology at the ICRC, have since proposed rules of engagement for civilian hackers in 2023. [84] The rules seek to mitigate or prevent any cyber attacks on civilian objects, infrastructure, and essential services, while encouraging states to implement "national laws that regulate civilian hacking."
The organized International Red Cross and Red Crescent Movement is a humanitarian movement with approximately 16 million volunteers, members, and staff worldwide. It was founded to protect human life and health, to ensure respect for all human beings, and to prevent and alleviate human suffering.
A war crime is a violation of the laws of war that gives rise to individual criminal responsibility for actions by combatants in action, such as intentionally killing civilians or intentionally killing prisoners of war, torture, taking hostages, unnecessarily destroying civilian property, deception by perfidy, wartime sexual violence, pillaging, and for any individual that is part of the command structure who orders any attempt to committing mass killings including genocide or ethnic cleansing, the granting of no quarter despite surrender, the conscription of children in the military and flouting the legal distinctions of proportionality and military necessity.
The Convention relative to the Protection of Civilian Persons in Time of War, more commonly referred to as the Fourth Geneva Convention and abbreviated as GCIV, is one of the four treaties of the Geneva Conventions. It was adopted in August 1949, and came into force in October 1950. While the first three conventions dealt with combatants, the Fourth Geneva Convention was the first to deal with humanitarian protections for civilians in a war zone. There are currently 196 countries party to the 1949 Geneva Conventions, including this and the other three treaties.
A civilian is a person who is not a member of an armed force nor a person engaged in hostilities.
An unlawful combatant, illegal combatant or unprivileged combatant/belligerent is a person who directly engages in armed conflict in violation of the laws of war and therefore is claimed not to be protected by the Geneva Conventions. The International Committee of the Red Cross points out that the terms "unlawful combatant", "illegal combatant" or "unprivileged combatant/belligerent" are not defined in any international agreements. While the concept of an unlawful combatant is included in the Third Geneva Convention, the phrase itself does not appear in the document. Article 4 of the Third Geneva Convention does describe categories under which a person may be entitled to prisoner of war status. There are other international treaties that deny lawful combatant status for mercenaries and children.
The law of war is a component of international law that regulates the conditions for initiating war and the conduct of hostilities. Laws of war define sovereignty and nationhood, states and territories, occupation, and other critical terms of law.
Combatant is the legal status of a person entitled to directly participate in hostilities during an armed conflict, and may be intentionally targeted by an adverse party for their participation in the armed conflict. Combatants are not afforded immunity from being directly targeted in situations of armed conflict and can be attacked regardless of the specific circumstances simply due to their status, so as to deprive their side of their support.
Non-combatant is a term of art in the law of war and international humanitarian law to refer to civilians who are not taking a direct part in hostilities; persons, such as combat medics and military chaplains, who are members of the belligerent armed forces but are protected because of their specific duties ; combatants who are placed hors de combat; and neutral persons, such as peacekeepers, who are not involved in fighting for one of the belligerents involved in a war. This particular status was first recognized under the Geneva Conventions with the First Geneva Convention of 1864.
The Second Geneva Convention, officially the Convention for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea, is one of the four treaties of the Geneva Conventions. The Geneva Convention for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea was first adopted in 1949, replacing the Hague Convention (X) of 1907. It adapts the main protective regime of the First Geneva Convention to combat at sea.
The First Geneva Convention, officially the Convention for the Amelioration of the Condition of the Wounded in Armies in the Field, held on 22 August 1864, is the first of four treaties of the Geneva Conventions. It defines "the basis on which rest the rules of international law for the protection of the victims of armed conflicts."
International humanitarian law (IHL), also referred to as the laws of armed conflict, is the law that regulates the conduct of war. It is a branch of international law that seeks to limit the effects of armed conflict by protecting persons who are not participating in hostilities and by restricting and regulating the means and methods of warfare available to combatants.
Protocol I is a 1977 amendment protocol to the Geneva Conventions concerning the protection of civilian victims of international war, including "armed conflicts in which peoples are fighting against colonial domination, alien occupation or racist regimes". In practice, Additional Protocol I updated and reaffirmed the international laws of war stipulated in the Geneva Conventions of 1949 to accommodate developments of warfare since the Second World War (1937–1945).
Protocol II is a 1977 amendment protocol to the Geneva Conventions relating to the protection of victims of non-international armed conflicts. It defines certain international laws that strive to provide better protection for victims of internal armed conflicts that take place within the borders of a single country. The scope of these laws is more limited than those of the rest of the Geneva Conventions out of respect for sovereign rights and duties of national governments.
The International Committee of the Red Cross (ICRC) is a humanitarian organization based in Geneva, Switzerland, and is a three-time Nobel Prize laureate. The organization has played an instrumental role in the development of rules of war and promoting humanitarian norms.
Protective signs are legally protected symbols to be used during an armed conflict to mark persons and objects under the protection of various treaties of international humanitarian law. While their essential meaning can be summarized as "don't shoot" or "don't attack", the exact conditions implied vary depending on the respective sign and the circumstances of its use. The form, shape and color of these signs are defined by the rules of international humanitarian law. Usually, they are easy to draw in order to make even an improvised use as easy as possible, and they were chosen to be as concise, recognizable and visible as possible under all circumstances.
The Martens Clause is an early international law concept first introduced into the preamble of the 1899 Hague Convention II – Laws and Customs of War on Land. There are differing interpretations of its significance on modern international law, with some scholars simply treating the clause as a reminder international customary law still applies after a treaty is ratified while others take a more expansive approach where the clause provides that because international treaties cannot be all encompassing, states cannot use that as a justification for an action.
The Rule of Law in Armed Conflicts Project is an initiative of the Geneva Academy of International Humanitarian Law and Human Rights to support the application and implementation of the international law of armed conflict.
The Geneva Convention for the Amelioration of the Condition of the Wounded and Sick in Armies in the Field, consisting of 39 articles in French, was adopted on 27 July 1929, at the end of the Diplomatic Conference of Geneva of 1929, which met from the 27 July until the 1 August of that year.
Protected persons is a legal term under international humanitarian law and refers to persons who are under specific protection of the 1949 Geneva Conventions, their 1977 Additional Protocols, and customary international humanitarian law during an armed conflict.
The prohibition of torture is a peremptory norm in public international law—meaning that it is forbidden under all circumstances—as well as being forbidden by international treaties such as the United Nations Convention Against Torture.
The undersigned Plenipotentiaries of the Governments represented at the Diplomatic Conference held at Geneva from April 21 to August 12, 1949, for the purpose of revising the Geneva Convention for the Relief of the Wounded and Sick in Armies in the Field of July 27, 1929 [...]
The undersigned Plenipotentiaries of the Governments represented at the Diplomatic Conference held at Geneva from April 21 to August 12, 1949, for the purpose of revising the Xth Hague Convention of October 18, 1907 for the Adaptation to Maritime Warfare of the Principles of the Geneva Convention of 1906 [...]
The undersigned Plenipotentiaries of the Governments represented at the Diplomatic Conference held at Geneva from April 21 to August 12, 1949, for the purpose of revising the Convention concluded at Geneva on July 27, 1929, relative to the Treatment of Prisoners of War [...]
In the relations between the Powers who are bound by the Hague Conventions respecting the Laws and Customs of War on Land, whether that of July 29, 1899, or that of October 18, 1907, and who are parties to the present Convention, this last Convention shall be supplementary to Sections II and III of the Regulations annexed to the above-mentioned Conventions of The Hague.
Article 49 of the 1949 Geneva Convention I, Article 50 of the 1949 Geneva Convention II, Article 129 of the 1949 Geneva Convention III and Article 146 of the 1949 Geneva Convention IV provide: The High Contracting Parties undertake to enact any legislation necessary to provide effective penal sanctions for persons committing, or ordering to be committed, any of the grave breaches of the present Convention defined in the following Article. Each High Contracting Party shall be under the obligation to search for persons alleged to have committed, or to have ordered to be committed [grave breaches of the 1949 Geneva Conventions], and shall bring such persons, regardless of their nationality, before its own courts. It may also, if it prefers, and in accordance with the provisions of its own legislation, hand such persons over for trial to another High Contracting Party concerned, provided such High Contracting Party has made out a prima facie case.
