With the recent international attention to riot control agents (RCA) people have raised the question how their use against protesting civilians can be legal when the toxic agents are internationally banned from battlefields.
Framed as such, the question is not entirely correct. In my previous blog posting I argued that outlawing RCAs for law enforcement and riot control based on the above reasoning may run into complications in the United States because the country still identifies operational military roles for irritants on the battlefield in contravention of the Chemical Weapons Convention.
This article sketches the convoluted history of harassing agents as a means of combat and a police tool. For hundreds of centuries until the late Middle Ages irritants were part of siege warfare. In the 19th century interest returned because of a new competition between defensive structures and breaching weaponry. Just like in earlier times, toxic fumes could drive defenders from their enclosed positions. The rise of chemistry introduced new compounds with the potential to clear occupants from fortifications.
Just before World War 1 French police had to confront a new form of gangsterism. Bandits used the most advanced weaponry and tools not yet available to police officers, they barricaded themselves in buildings, and resisted arrest until their last bullet. To reduce bloodshed, the police investigated alternatives to dislodge the new creed of brigands.

Origins and negotiation of Article VII of the Biological and Toxin Weapons Convention
A new research report
Article VII of the Biological and Toxin Weapons Convention (BTWC) belongs to the more obscure provisions. It reads as follows:
Each State Party to this Convention undertakes to provide or support assistance, in accordance with the United Nations Charter, to any Party to the Convention which so requests, if the Security Council decides that such Party has been exposed to danger as a result of violation of the Convention.
Since the treaty’s entry into force in 1975, states parties hardly looked at the one-paragraph article. Up to the 7th Review Conference (2011) the only additional understandings and agreements concerned general implementation procedures and possible roles of appropriate international organisations, including the World Health Organisation (WHO), the World Organisation for Animal Health (OIE) and the Food and Agricultural Organisation (FAO), as well as coordination functions for the United Nations (UN). Attention to the article increased markedly at the 7th Review Conference, a consequence of a heightened perceived worldwide risk from emerging and re-emerging diseases, fears of outbreaks resulting from biosecurity and -safety lapses in high-containment laboratories, concerns about scientific and technological advances in the life sciences that could be misused for hostile purposes, potential terrorist or criminal interest in highly contagious pathogens, and so on. The Ebola outbreak in West Africa between 2013–16 and subsequent evaluation of the international response raised concerns among the BTWC states parties about how the international community might respond to a deliberate disease outbreak, whether as a consequence of an act of war or terrorism.
These trends have led to an affirmation of the humanitarian dimension of Article VII. As Nicholas Sims noted in his study of the treaty’s early functioning (The Diplomacy of Biological Disarmament. 1988, p. 24): ‘Statements made in the UN, with an eye on future references to the negotiating history of the convention, indicate that this article is generally understood to refer to humanitarian, not military, assistance.’ With nothing seemingly contradicting today’s humanitarian imperative, most attention has so far gone to the organisation and coordination of international response to the release of a highly infectious biological weapon (BW).
Questions about triggering Article VII
Much less understood is how Article VII can be activated. There are no procedures; there has not been any determination who should be involved in the process. Which are the (possible) roles for the BTWC Implementation Support Unit (ISU), the treaty’s three depositary states (Russia, United Kingdom and United States), the UN Secretary-General (UNSG), or the UNSC is a question that remains unanswered. It should be added in this context that some actors or available tools are of much more recent origin and were consequently not envisaged during the treaty negotiation. The mandate for the ISU was decided at the 6th Review Conference (2006). The UNSG’s mechanism to investigate allegations of chemical and biological weapons (CBW) use received endorsement from the UNSC and the UN General Assembly (UNGA) in 1988 and has since then been strengthened. Through the review process, BTWC states parties have elaborated a consultative mechanism under Article V to address compliance concerns.
Moreover, given the humanitarian framework guiding today’s debates on implementing Article VII, from the perspective of triggering the provision there are several dissonant elements. The article has its origins in a 1968 working paper by the United Kingdom proposing a separate treaty banning biological warfare. The language underwent several reiterations over the next three years and at one point disappeared entirely from the draft convention, only to resurface in its current formulation just before the conclusion of the negotiations. The different versions of the article left traces from earlier intentions and understandings, meaning that the intent behind certain phrases that may be uncertain or appear confusing today. This is particularly the case for the following:
- provide or support assistance: what is the nature of the assistance, humanitarian, military, or any other type?
- in accordance with the United Nations Charter: why does the article include a reference to the UN Charter, particularly since the Charter allows for punitive actions and even resort to military force under Chapter VII? In addition, if the assistance is humanitarian, as assumed today, what prompted the reference to the UN Charter? The word ‘humanitarian’ features only once in the founding text (Chapter I, Article 1, 3); the words ‘aid’ or ‘assistance’ (in the sense of humanitarian or non-military aid) are absent. Furthermore, while the UN’s mandate includes the promotion of arms control and disarmament, nothing in the Charter makes it responsible for monitoring treaty compliance or addressing treaty violations. Besides Article VII, only Articles V and VI refer to the Charter or UNSC. The context concerns the resolution of any problems relating to the BTWC’s objective, way of implementation, or breaches of the convention.
Article V raises the possibility of organising bi- and multilateral consultations and cooperation ‘through appropriate international procedures within the framework of the United Nations and in accordance with its Charter’ in case direct interaction between the parties concerned is impossible or unproductive. Overall the provision is vague. Review conferences have tried to clarify it, in particular with regard to the convening of a consultative meeting. Article VI grants a state party the right to lodge a complaint with the UNSC if it believes that another state party has breached its treaty obligations. Furthermore, should the UNSC initiate an investigation, all states parties undertake to cooperate with such investigation. However, states parties have not elaborated on the references to the UN Charter and the UNSC. They have also not answered whether there is or should be any linkage between either Articles V or VI and Article VII.
- if the Security Council decides that such Party has been exposed to danger: why is there a requirement for Security Council action if assistance can be provided under basic humanitarian principles? On what basis will the UNSC make this decision? The Third and Fourth Review Conferences (1991 and 1996) noted under both Articles V and VI the UNSG’s investigative mechanism as endorsed in UNSC Resolution 620 (1988) and UNGA Resolution 45/57 (1990) and ‘to consult, at the request of any State Party, regarding allegations of use or threat of use of bacteriological (biological) or toxin weapons and to cooperate fully with the United Nations Secretary-General in carrying out such investigations’. Later review conferences refer back to this text and have not elaborated any further on the references to the UN Charter or the UNSC. The UNSC, as its name indicates, bears primary responsibility for the maintenance of international peace and security (Chapter V, Article 24, 1). Logic therefore suggests that Article VII applies exclusively to the deliberate use of a pathogen or toxin as a weapon. This would thus exclude a situation of a country facing an outbreak after an accidental release of a disease-causing agent from a neighbour’s secret BW research or production facility (similar to the anthrax outbreak near Sverdlovsk in 1979). In other words, according to this interpretation Article VII refers to an act of war, even though the BTWC lacks references to ‘use’ in both its title and Article I.
- as a result of violation of the Convention: does this clause imply violation of any part of the BTWC? If affirmative, this could include illicit weapon programmes or outbreaks resulting from illicit activities. How would this square with the interpretation that Article VII only refers to an act of war?
Furthermore, only states parties can violate the BTWC, which implies that dangers arising from other actors—non-states parties (signatory or non-signatory states) or non-state actors—could not be the subject of Security Council action, and therefore not of state party assistance.
Aim of the research paper
In November 2016, in the margins of the 8th Review Conference of the BTWC, the Fondation pour la recherche stratégique (FRS) and UN Institute for Disarmament Research (UNIDIR) held a tabletop exercise (TTX) to understand better the elements that would have to be in place to trigger Article VII and the consequences such action may have on the organisation of international assistance. The TTX revealed that decision-making was severely hampered because of the article’s lack of clarity, uncertainty about possible procedures and their consequences on the process as a whole, and the types of actors that could be called upon (e.g. UNSG, ISU, depositary states, etc.).
Discussions at a workshop on ‘Article VII of the BWC and the UN System’, held in New York on 12–13 December 2017 as part of the Project on strengthening global mechanisms and capacities for responding to deliberate use of biological agents, also touched upon the specific responsibilities of UN organs following activation of Article VII. The question was raised whether there was any relevancy in trying to recover the negotiators’ original intentions. In reply, UN officials said that since the implications of triggering Article VII had never been studied and no procedures have ever been put in place, following a request the first task for the UN would be to study legal and negotiation documents to determine which types of action might be possible and which roles the UNSC and UNSG might play.
This research paper traces the article’s negotiation history between 1968 and 1971. During those three years negotiations took some sharp turns, and draft treaty texts were dropped and replaced by alternatives that framed BW control in radically different ways. In the final two months of negotiation, some degree of synthesis between different approaches took place. With respect to Article VII, when Morocco introduced an amendment to reinsert language based on the British proposal of August 1971, the context had completely changed, not in the least because the original draft provisions banning methods of biological warfare and a mechanism to investigate allegations of BW use had been dropped. Whereas Article IV in the original British draft convention formed part of the fabric to prevent biological warfare, the later Article VII had no obvious connections to the BTWC’s core prohibitions in Articles I – III. It also lacked direct or explicit links to Articles V and VI.
Moreover, the humanitarian intent, systematically affirmed by British government officials and diplomats, became blurred at times, especially after an addition to a draft UNSC resolution that was to accompany the BTWC made explicit reference to Article 51 of the UN Charter on individual and collective self-defence. It shifted the focus away from aiding the victim of a biological attack to possible assistance in countering the aggressor.

The introduction of chemical warfare to the battlefield on 22 April 1915 changed the face of total warfare. Not only did it bring science to combat, it was both the product of societal transformation and a shaper of the 20th century societies.
This collaborative work investigates the unfolding catastrophe that the unleashing of chlorine against the Allied positions meant for individual soldiers and civilians. It describes the hesitation on the German side about the effectiveness, and hence impact on combat operations of the weapon whilst reflecting on the lack of Allied response to the many intelligence pointers that something significant was afoot.
It goes on to describe the massive transformation that societies were undergoing as a consequence of industrialisation, science and technology, and the impact these trends were to have on the emergence of what we know today as ‘total war’. Chemical warfare pitted the brightest minds from the various belligerents against each other and in some ways this competition revealed early thinking about intellectual superiority that was to define the decades after the Armistice. The ability to survive in a chemically contaminated environment was proof of a higher level of achievement. In simple terms, chemical defence equalled survival of the fittest.

Today, 17 June, the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare celebrates its 90th anniversary. Short as the document is, it laid the foundations for the 1972 Biological and Toxin Weapons Convention (BTWC) and the 1993 Chemical Weapons Convention (CWC). How critical that document was to disarmament—the total elimination of a given weapon category—the global community can only appreciate through the growing frustration with the lack of progress in the elimination of nuclear weapons. As the negotiators of the Geneva Protocol came to understand in 1925, without a global ban on use, no other weapon-related activities could legally be curtailed.
This three-part analysis retraces the origins of the Geneva Protocol and identifies its implications for disarmament.
Part 1 focusses on the discovery of the dual-use dilemma posed by toxic chemicals and the conclusions the negotiators drew from their new insights.
Part 2 analyses how the negotiators resolved the dual-use dilemma in meetings preparing the disarmament conference of the 1930s, and in the process came up with solutions that make up the pillars of disarmament today.
Part 3 reflects on how the Geneva Protocol experience may point to a tangible nuclear disarmament strategy in view of the failure of the 2015 review conference of the Nuclear Non-Proliferation Treaty (NPT) and the difficulties in reaching a satisfactory agreement with Iran to shed more transparency on its nuclear activities.
On 20–21 March the University of Rome III hosted a roundtable discussion to reflect on the current status of the prohibition on chemical weapons (CW) and the future challenges to that ban. Although convened by the Law Department, the speakers represented an eclectic group of experts with backgrounds in international law, political sciences, chemistry and biology, as well as practitioners. Notwithstanding, the meeting yielded considerable coherence in arguments, with questions, challenges and supplementary insights contributing further to an already rich multi-disciplinary texture.
The Chemical Weapons Convention (CWC) is at the heart of today’s prohibition on CW and their use in armed conflict. However, it does not stand in isolation. In fact, one could build a case that the norm against CW has a variable geometry. Approach it from the ban on chemical warfare, and the 1925 Geneva Protocol and its links to the International Criminal Court or the United Nations—in particular, the UN Secretary-General’s mechanism to investigate alleged use of chemical or biological weapons (CBW)—may take centre stage. Approach it from the angle of scientific and technological developments, and the 1972 Biological and Toxin Weapons Convention (BTWC) emerges as a possible point of entry. Approach it from the threats posed by terrorism and UN Security Council resolutions, including 1540 (2004), with their demands for national legislative action come into play. And so on. The various tools available today have created mutually reinforcing bridges. However, they are also the source of contradictions and large gaps remain between them. As the Rome roundtable brought out, it is not always clear how they can be reconciled or filled.
And then, of course, there are the politics. As we are about to commemorate the centenary of the outbreak of the First World War and are just eight days before the 99th anniversary of the chlorine attack near Ypres, Syria’s civil war shows that humanity still has not been fully able to relegate these weapons to history. And while political leaders of the great powers loudly invoke the inhumanity of poison weapon use, their actions today—just like those during the Abyssinian war in the 1930s, the Yemen war in the 1960s, the Iran–Iraq war of the 1980s—demonstrate once again that other geopolitical considerations, national security interests or domestic political agendas trump halting chemical warfare and holding the culprits accountable under international law. (True, some would argue that the 2003 invasion of Iraq served such a purpose, but alas, few are those who believe the proffered unbelievable unbelievables.)
Unsurprisingly therefore, Syria made up one of the main threads tying the various sessions together. But it was not the only one: other recent issues pose remarkably similar challenges to the future of the prohibition on CW. This blog posting summarises the presentations and offers a few personal reflections on points raised during the discussions.
This morning the UN Human Rights Council published the report of the Independent International Commission of Inquiry on the Syrian Arab Republic (ICI).
While detailing the horrors of the escalating civil war and the atrocities committed by both sides, the document was eagerly awaited after Commissioner Carla del Ponte had claimed on Swiss-Italian television four weeks ago that the ICI has evidence of rebel use of chemical weapons (CW). She added that it still had to see direct evidence of government chemical warfare. The next day the ICI clarified that ‘it has not reached conclusive findings as to the use of chemical weapons in Syria by any parties to the conflict. As a result, the Commission is not in a position to further comment on the allegations at this time’. Despite its terseness, it did not exactly refute del Ponte’s asseveration.
The 29-page ICI report, however, supports none of the details in her television interview. The introductory summary notes that ‘there are reasonable grounds to believe that chemical agents have been used as weapons’, but ‘the precise agents, delivery systems or perpetrators could not be identified’. CW are addressed in more detail in Part IV(D) on Illegal Weapons:
136. As the conflict escalates, the potential for use of chemical weapons is of deepening concern. Chemical weapons include toxic chemicals, munitions, devices and related equipment as defined in the 1997 Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and Their Destruction. Also applicable is the 1925 Geneva Protocol which Syria has ratified. The use of chemical weapons is prohibited in all circumstances under customary international humanitarian law and is a war crime under the Rome Statute.
137. The Government has in its possession a number of chemical weapons. The dangers extend beyond the use of the weapons by the Government itself to the control of such weapons in the event of either fractured command or of any of the affiliated forces gaining access.
138. It is possible that anti-Government armed groups may access and use chemical weapons. This includes nerve agents, though there is no compelling evidence that these groups possess such weapons or their requisite delivery systems.
139. Allegations have been received concerning the use of chemical weapons by both parties. The majority concern their use by Government forces. In four attacks – on Khan Al-Asal, Aleppo, 19 March; Uteibah, Damascus, 19 March; Sheikh Maqsood neighbourhood, Aleppo, 13 April; and Saraqib, Idlib, 29 April – there are reasonable grounds to believe that limited quantities of toxic chemicals were used. It has not been possible, on the evidence available, to determine the precise chemical agents used, their delivery systems or the perpetrator. Other incidents also remain under investigation.
140. Conclusive findings – particularly in the absence of a large-scale attack – may be reached only after testing samples taken directly from victims or the site of the alleged attack. It is, therefore, of utmost importance that the Panel of Experts, led by Professor Sellström and assembled under the Secretary General’s Mechanism for Investigation of Alleged Use of Chemical and Biological Weapons, is granted full access to Syria.
Is there anything new?
The strongest refutation of del Ponte comes in §138: insurgents ‘may access and use’ CW refers to a future possibility, not events in a recent past. The 430 interviews and other evidence collected between 15 January and 15 May 2013 yielded ‘no compelling evidence that these groups possess such weapons or their requisite delivery systems’.
Although the next paragraph states that ‘allegations have been received concerning the use of chemical weapons by both parties’, it does not specify from whom the ICI obtained this information. Listing the main allegations between March and mid-May, the sources may just as well have been the UN Secretary General, the formal requests to Ban Ki-moon by Syria, UK and France to launch a formal investigation of alleged use, or the many media reports. It does not assert, as del Ponte did, that ‘Our investigators have been in neighbouring countries interviewing victims, doctors and field hospitals and, according to their report of last week which I have seen, there are strong, concrete suspicions but not yet incontrovertible proof of the use of sarin gas, from the way the victims were treated.’ As a matter of fact, the ICI document does not mention sarin a single time. The mere assumption that no UN member would submit to the Secretary general a frivolous request for an onsite investigation allows the Commissioners to write in the introductory summary that there are reasonable grounds to believe that CW have been used, possibly by both sides. In §140 the ICI nonetheless comes to the obvious conclusion that confirmation or refutation of the allegations will be possible only after samples retrieved directly from victims or the site of the alleged attack by an independent international expert team have been tested.
Much ado about nothing?
It is a plain shame that Carla del Ponte has felt the need to join the global chorus of blabberati. Commentaries will invariably focus on her statements, or on whether the ICI document buttresses the Obama Administration’s position that its self-proclaimed red line has not yet been crossed.
Yet, despite the brevity of the section on CW allegations, the report adopts some remarkably thinking in §136:
- It accepts the Chemical Weapons Convention (CWC) as a foundation of international criminal law. In particular, it embraces the wide-ranging definition of a CW, which means that for criminal prosecution no discrimination between warfare agents based on an ill-defined lethality criterion is acceptable. The CWC applies to incapacitants and irritants (such as riot control agents, for instance, tear gas), as well as to industrial chemicals such as chlorine (a warfare agent of World War I vintage). Whatever toxicant any belligerent may choose to use, it will fall under the remit of an international criminal court for Syria. This statement may well be a first! (See, for example, Yasemin Balci’s discussion of criminal law in Future of the CWC in the Post-Destruction Phase.)
- It also refers to the applicability of 1925 Geneva Protocol prohibiting the use of chemical and biological weapons in armed conflict and emphasises Syria’s ratification. The phrasing is interesting, because it juxtaposes rather than cascades both international agreements, thus implying that the scope of the CWC definition of a CW also applies to the Geneva Protocol.
- It declares CW use as prohibited in all circumstances under customary international humanitarian law and determines that it is a war crime under the Rome Statute. Most significantly, it does so in a separate sentence and without specific referral to the Geneva Protocol. Usually, scholars, lawyers and officials will assert that the Geneva Protocol has entered customary international law. According to their phrasing, the ICI Commissioners strongly suggest that the CWC equally informs the customary norm, which is not without consequence given their emphasis on the CWC definition of a CW. It definitely sharpens the boundaries of a war crime as defined under the Rome Statute.
These points will be and have to be the subject of legal debate to bolster the CW prohibition under any and all circumstances.
