EJIL Talk! Book Discussion: Djemila Carron’s Response

Published on June 2, 2017        Author: 

This post is part of our book discussion on Djemila Carron’s “L’acte déclencheur d’un conflit armé international“.

Introduction

I am grateful to the editors of EJIL: Talk! for organizing this discussion – the first one around a book in French! I also would like to warmly thank Professor Julia Grignon and Doctor Tristan Ferraro – whose articles, books and reflections were very important while writing L’acte déclencheur d’un conflit armé international – for their thoughtful comments on my work. In this contribution, I consider some of the questions they raise in each of their pieces, mainly on the capture of a soldier as a triggering act of an IAC (response to Julia Grignon) and on the classification of transnational armed conflict (response to Tristan Ferraro).

Animus belligerendi

I will not respond in detail to Julia Grignon’s development of my rejection of a criteria of animus belligerendi for the existence of an IAC (Part II, Question VI). She perfectly summed up my main arguments. The intent of a State to be in an IAC or in a state of war has no influence on the existence of an IAC. Once again, to exclude subjective elements from the definition of an IAC was one of the key reason for the shift in 1949 from the notion of war to the one of IAC. This said, as explained in the book, for such a conflict to take place, a State must nevertheless have the intent to use force against another one. I propose to defend this element through the objective requirements on the origin of an IAC (Part II, Question IV). In other words, if a State uses force against another one through its organs, acting in their capacity, following instructions and not mistakenly, the animus to use force is considered fulfilled.

Arms Exports to Saudi Arabia in the High Court: what is a “serious violation of international humanitarian law”?

Published on April 3, 2017        Author: 

As readers will be aware, the UK High Court is presently considering a high-profile case challenging UK arms exports to Saudi Arabia. Arguments in the judicial review proceedings brought by Campaign Against Arms Trade were heard in February and judgment is awaited.

Although brought under English law, the case potentially implicates various international law questions. This post focuses on the interpretation of the expression “serious violation of international humanitarian law” (“IHL”) which the government appears to be advancing in the case. By narrowing the concept to include only war crimes, its position has significant implications for the international law regulation of the arms trade in general. This post will argue that the proposed definition should be rejected.

For further information on this and other international law issues arising in the case, the claimant has posted much of the open documentation produced by both sides on its website. This post draws heavily on those documents, and on the author’s notes of the open hearings.

The Issue Before the Court

The claimant challenges the government’s decisions to continue granting licences (and not to suspend existing licences) for arms exports to Saudi Arabia. That challenge is based primarily on alleged breaches of IHL by Saudi forces involved in the ongoing armed conflict in Yemen. Criterion 2(c) of the UK statutory guidance applicable to arms exports (the “Consolidated Criteria”) prohibits granting a licence “if there is a clear risk that the items might be used in the commission of a serious violation of international humanitarian law”. The claimants argue that given the evidence of previous breaches, the government should have concluded that such a clear risk existed. Read the rest of this entry…

North Korea and the Law on Anticipatory Self-Defense

Published on March 28, 2017        Author: 

Media reports over the last few weeks indicate that the already tense relationship between North Korea and the United States is getting worse. Now that North Korea is nearly ready to test an intercontinental ballistic missile, the United States has said that it will get more confrontational. U.S. Secretary of State Rex Tillerson even suggested that U.S. military action against North Korea is “on the table.” Such talk is sometimes part of a broader strategy to pressure other countries to negotiate, whether at the Security Council or elsewhere. But it can also be a precursor to war. And it comes at an acute time for the law on anticipatory self-defense.

As readers of this blog no doubt know, Article 51 of the UN Charter recognizes that states have an “inherent” right to use force in self-defense “if an armed attack occurs.” There is an ongoing debate about whether and, if so, when Article 51 permits states to use force to avert an attack that has not yet occurred. Claims for interpreting Article 51 expansively—to permit defensive force even if the attack is only speculative—have been made with respect to “rogue” states that are developing nuclear weapons. In this post, I situate the North Korea case within that debate and explain why the United States might find it to be a particularly challenging case in which to press its expansive claim.

I. The Law on Anticipatory Self-Defense

A. A Restrictive Position

 The majority view on anticipatory self-defense is probably a restrictive one: that anticipatory self-defense can be lawful only if an attack is truly “imminent”—as in, about to occur. Under this view, states may not use force unilaterally to nip in the bud latent threats or attacks that are still conjectural. They must instead address those situations using non-forcible means or by obtaining the UN Security Council’s authorization. Read the rest of this entry…

The Use of Cluster Munitions by Saudi Arabia in Yemen and the Responsibility of the United Kingdom

Published on March 7, 2017        Author: 

In December 2016, after repeated denials, Ahmed Asiri, a spokesman for the Saudi-led coalition fighting in Yemen, said: ‘It has become apparent that there was limited use by the coalition of the UK-manufactured BL755 cluster munition in Yemen’. This admission opened up questions about the United Kingdom’s potential responsibility for the use of cluster munitions by the Kingdom of Saudi Arabia. Britain’s Defence Secretary Michael Fallon informed the Commons that the munitions used by Saudi Arabia had been delivered in the 1980s, well in advance of the entry into force for the United Kingdom of the Convention on Cluster Munitions (‘the Convention’) on 1 November 2010. The treaty was implemented through the Cluster Munitions (Prohibitions) Act 2010 (‘the Act’).

 A judicial review of the granting of export licences to Saudi Arabia is currently taking place in the English High Court, following an application by the Campaign Against the Arms Trade (see here). The application focuses on export licences for weapons in general, and follows allegations of violations of international humanitarian law by Saudi Arabia, including, but not limited, its use of cluster munitions.

In this post, I focus on the specific responsibility of the UK arising under the Convention on Cluster Munitions for the use by Saudi Arabia of UK-provided aircraft, and support by British personnel.

The post addresses three issues: first, whether issuing export licences for aircraft to Saudi Arabia can be construed as a breach of Article 1(c) of the Convention; second, whether the exception on interoperability in Article 21 of the Convention covers the acts by the UK in respect to the use of cluster munitions by Saudi Arabia; and third, whether the UK’s responsibility could also arise also under Article 16 of the Draft Articles on the Responsibility of States for Internationally Wrongful Acts (‘the 2001 Articles’).

Due Diligence Obligation in Times of Crisis: A Reflection by the Example of International Arms Transfers

Published on March 1, 2017        Author: 

This post is part of the ESIL Interest Group on International Human Rights Law blog symposium on ‘The Place of International Human Rights Law in Times of Crisis’.

In this blog post, I would like to take up a question that I discussed at the ESIL Human Rights Interest Group in Riga and analyze whether the due diligence obligation under international human rights law (IHRL) plays a role in the regulation of crisis in order to prevent or mitigate state action that has a negative impact on human rights, and what role that might be.

In doing so, I will use the debate emerging in the wake of the ongoing ‘crisis’ in the Middle East on international arms transfers by foreign governments, for instance, to the Syrian rebels or the Kurdish forces in Northern Iraq, to support the fight against IS. International arms transfers in the form of emergency military aid has drawn into the limelight the issue as to whether the recipients of the supplied arms would be able to control them or if these weapons may fall into the hands of non-intended end-users, such as private parties, likely be used to commit human rights violations on the recipient’s territory (which is what in fact happened, see here or here).

The Problématique: Attribution of Conduct

As a general principle, the acts of non-state actors fall out of the scope of the rules of state responsibility, unless they are acting under the direction or control of a state (see Article 8 of the ILC Draft Articles on State Responsibility). Crisis-related scenarios are especially characterized in a way that human rights abuses occur either due to a general situation where the wrongful conduct in question is not identifiable (e.g. in armed conflicts, natural disasters or disease outbreaks) or where acts of non-state actors are not attributable to a state due to lack of control. This might be the case in armed conflicts where third states do not engage in direct attacks but are interfering indirectly by means of state assistance (e.g. military aid in the form of arms transfers).

Whose Security is it Anyway? Towards a Treaty Prohibition of Nuclear Weapons

Published on May 31, 2016        Author: 

On Friday, 13 May 2016, the UN’s Open Ended Working Group (OEWG), convened pursuant to UNGA resolution 70/33 (7 Dec 2015) and mandated, inter alia, to “substantively address concrete effective legal measures, legal provisions and norms that would need to be concluded to attain and maintain a world without nuclear weapons”, closed its second session with a majority of states calling for negotiations of a legally binding instrument (or instruments) to prohibit nuclear weapons to start in 2017.

Although (or perhaps because) the nuclear-armed states have chosen not to play ball, for the first time in decades, a treaty outlawing nuclear weapons is a real possibility. The OEWG, which will meet for a third time in August to agree on recommendations to the UNGA, and the ensuing tug-of-war in the UNGA’s First Committee in October, offer an historic opportunity for multilateral nuclear disarmament negotiations to take a big step forward. The reframing of nuclear disarmament as a humanitarian concern has been instrumental in generating strong momentum in support of negotiations. This post surveys some of the legal controversies that arose during the OEWG and explains why, from a humanitarian disarmament perspective, a treaty prohibition of nuclear weapons is both imperative and an effective disarmament measure, even without the participation of the nuclear-armed states.

Open to all, the OEWG’s May session has been attended by 100 states, as well as international organizations and civil society representatives, including survivors of the atomic bombings. None of the nuclear-armed states, i.e. the Nuclear Weapon States (NWS) recognized under the 1968 Nuclear Non-Proliferation Treaty (NPT) –China, France, Russia, the UK and the US – nor the DPRK, India, Israel or Pakistan, participated, casting further doubt on the good faith performance of nuclear disarmament obligations by the respondents in the RMI cases pending before the ICJ.

There is general agreement that the ultimate objective is a world free of nuclear weapons. To that end, all states parties to the NPT (and arguably, all states) have a legal duty to “pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament” pursuant to Art. VI, NPT and customary international law. Views diverge, however, on the pathways, means and urgency with which this goal should be attained. Read the rest of this entry…

“Are you smarter than Professor Hawking?” Higher Forces and Gut-Feelings in the Debate on Lethal Autonomous Weapons Systems

Published on April 27, 2016        Author: 

“Professor Hawking says that artificial intelligence without control may cause the extinction of the human race”, noted a Chinese delegate following a session on ‘mapping autonomy’ at the Convention on Conventional Weapons (CCW) meeting of experts which took place from 11-15 April 2016 at the United Nations in Geneva. The CCW convened its third meeting of experts to continue discussions on questions related to emerging technologies in the area of lethal autonomous weapons systems (LAWS) and I had the privilege of participating.

LAWS are most often described as weapons that are capable of selecting and attacking targets without human intervention; one of the key questions addressed at the meeting was what exactly this means. According to most of the commentators present at the meeting, LAWS do not yet exist however, the possibility of using autonomous weapons in targeting decisions raises multidisciplinary questions that touch upon moral and ethical, legal, policy, security and technical issues. The meeting addressed all of these, starting with the technical session aimed at mapping autonomy.

Without expressing their position on a ban, the six technical experts on the panel presented a nuanced view of the state of current autonomous weapons technology and the road that lies ahead. The Chinese were one of the first delegations to respond to the panel and the delegate seemed startled; some of what was said seemed to contradict the conclusions reached by Professor Hawking et al. China read the Open Letter issued by the Future of Life Institute (FLI) and signed by thousands of artificial intelligence (AI) and robotics researchers, as well as by a number of other endorsers including the well-known Professor Stephen Hawking. The Open Letter calls for a ban on offensive autonomous weapons beyond meaningful human control, claiming that these weapons would be feasible within years, not decades. The Open Letter attracted a good deal of attention, largely because it is signed by a number of well-regarded figures including, Tesla CEO Elon Musk, Apple co-founder Steve Wozniak and as previously mentioned, Professor Stephen Hawking.

The expert panelists offered some divergent views on the claims and predictions made in the Open Letter. In response to these, China asked the panelists “do you think you are smarter than Professor Hawking?” A number of delegates, academics, NGO members and panelists seemed quite amused by the provocative question posed by China. Who dares to disagree with Hawking? Fortunately, some of the experts did. “Isn’t Hawking a physicist, and not an AI expert?”, asked one panelist. Another expert confidently said, “Yes, I am smarter than Stephen Hawking.” Why? “Because, like Plato, I know that I do not know.” The debate is amusing, but also a little bit troublesome. What is the effect of well-regarded figures on the discourse about autonomous weapon systems? Read the rest of this entry…

Corbyn, Trident, and the Letter of Last Resort: Legality of Use of Nuclear Weapons

Published on October 6, 2015        Author: 

Jeremy Corbyn’s election to the leadership of the Labour Party in the United Kingdom by a landslide victory last month has renewed discussions in the UK about the ‘nuclear deterrent’. Corbyn, a long time anti-war activist and Vice-Chair of the Campaign for Nuclear Disarmament (CND) has, for many years, taken a very public and unequivocal stance against the use of nuclear weapons and in favour of scrapping the UK’s Trident nuclear weapons system. The Trident system is composed of submarine-launched ballistic missiles carried by four Vanguard-class submarines: HMS Vanguard, HMS Victorious, HMS Vigilant, and HMS Vengeance. One of those submarines is constantly on patrol somewhere around the globe. During the recent Labour Party conference, the party failed to take a position in favour of scrapping Trident, but its leader clearly and unequivocally stated that should he become Prime Minister of the UK, he would not use nuclear weapons. For this he was criticized both from within his own party, and beyond, as his statement would mean that were he to become Prime Minister, the UK would have effectively given up the possibility of any deterrent value of its nuclear arsenal.

It might be thought that even if Corbyn were to become Prime Minister the circumstances in which he would have to make a call as to whether to use nuclear weapons are very remote. Far from it! Each new Prime Minister of the UK must decide on the use of nuclear weapons in his or her first few days in office! This is when each new UK Prime Minister must draft the so-called ‘Letter of Last Resort’. This letter contains an instruction from the Prime Minister (indeed the final instruction) to the commanders of the Royal Navy submarines carrying the Trident system. The letter sets out what the commander is to do in case Britain has suffered a nuclear attack that has effectively destroyed the British state, resulted in the death of the Prime Minister and his or her nominated deputies, and led to a loss of contact between the submarine and the UK. There are a number of checks that must be carried out before the commander can presume that the UK has been attacked so devastatingly that nothing of the state and the chain of command remains. Apparently, one of those checks is to establish that BBC Radio 4 is no longer broadcasting! At that stage, the commander of the submarine is to obtain and fulfill the order stated in the letter of last resort, which is kept in the ship’s safe. No letter of last resort has been published. Each one is destroyed when a new PM takes office and issues a new letter of last resort. However, we do have some idea of the options available to the PM, which range from ‘scuttle the ship’, to ‘find and join the US or Australian Navy’, ‘retaliate’ or perhaps even ‘use your judgement’. (For a serious discussion of the Letter, listen to this BBC Radio 4 programme, for a more humorous discussion of the nuclear deterrent, watch this) .

Presumably, Corbyn’s letter of last resort will not involve a command to use the nuclear weapons aboard the vessel. However, it is interesting to consider whether an order to retaliate, in the circumstances in which a letter of last resort is actually opened, would be legal under public international law. To be sure, if such horrendous circumstances were to occur, we would be right at the vanishing point of the utility of law. Indeed, law, as well as other frameworks for organizing human society, would have failed us. However, thinking about whether a use of nuclear weapons (indeed any use of force) would be lawful in those circumstances helps us to understand what we think the purpose of the right of self-defence is, and how it ought to operate in international law.

Tears in Our Eyes: Third State Obligations in International Law

Published on July 30, 2015        Author: 

In early January 2015 the Republic of South Korea sold 1.9 million tear gas canisters to Turkey. With this sale came much campaigning against it. Amnesty International’s “Korea, do not sell us tear gas” campaign received over 50,000 signatures of support. The goal of this campaign was to highlight how the Turkish police force has been and continues to be to this day reckless and excessive in its use of tear gas on certain domestic demonstrations. Reckless and excessive use which, according to data collected by the Turkey Human Rights Joint Platform, led to the death of 19 Turkish citizens between 2006 and 2013 — including four children.

The sale of such large quantities of tear gas to a country that has a proven track record of using it frequently and recklessly raises important questions of international law. It raises questions in particular with regard to the responsibility of third states for internationally wrongful acts and the standard of proof required to establish such responsibility. Put simply, did South Korea commit an internationally wrongful act when it sold tear gas to Turkey?

Tear gas and international law

The name tear gas encompasses a group of substances that irritate mucous membranes and cause stinging sensations and tears. The effect of tear gas is normally considered temporary for a healthy adult so long as they are able to breathe fresh air shortly after exposure. Fatalities have been caused when tear gas has been used in closed spaces, on unhealthy adults or the elderly, or when canisters have been fired directly at protesters.

The use of tear gas is prohibited in wartime both by the 1925 Gas Protocol and the 1993 Chemical Weapons Convention.  The 1993 Convention, however, explicitly includes a clause in Article 1(5), inserted at the insistence of the United States, stating that “Each State Party undertakes not to use riot control agents as a method of warfare.” Article II(7) of the 1993 Convention further defines a “Riot Control Agent” as “Any chemical not listed in a Schedule, which can produce rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.” This clause, by implication, signals a regime of permissibility for riot control agents — including tear gas — during peacetime.

Security Council Resolution 2231 and the Joint Comprehensive Plan of Action on Iran’s Nuclear Program

Published on July 27, 2015        Author: 

Last week I did a couple of posts elsewhere on the Joint Comprehensive Plan of Action (JCPOA), agreed on July 14 between the P5+1 and Iran regarding Iran’s nuclear program. See here and here. These posts may be of interest in explaining the essential agreement contained in the JCPOA, and in examining some of its key legal implications.

The JCPOA is the culmination of twenty months of negotiations between the P5+1 and Iran, since the initial Joint Plan of Action (JPOA) was agreed by the parties in November 2013. I wrote a post discussing the JPOA here at EJIL:Talk! at the time it was agreed.

I’d like to focus this post on the unanimous passage by the U.N. Security Council on July 20 of Resolution 2231, which can be found here. Resolution 2231 comprises 104 pages of text, inclusive of two annexes, one of which is the entire JCPOA text. I mention this because my primary impression in reading over Resolution 2231 and is annexes for the first time, was frankly astonishment that the parties had been able to agree on such an amazingly complex, thorough and comprehensive diplomatic accord. I was also impressed by the precision of the text of Resolution 2231 itself (apart from a couple of typos) in implementing, in what appears to be a very sophisticated and, as far as I can tell, correct way, the agreement reached by the parties on July 14.

The JCPOA itself and Resolution 2231 appear to represent a major success of international diplomacy, as well as a significant achievement of international law in facilitating the implementation of the diplomatic accord. Again, it is difficult to overstate the complexity of the issues that had to be resolved among the parties to arrive at both the JCPOA and Resolution 2231. And the specificity with which these issues were addressed in both documents – down to weights and measures and dates of implementation – is frankly astonishing, and far exceeds my expectations.  And so I compliment all of the diplomats and lawyers involved.
