Courts & Tribunals

Mike Lewis has a guest post at Just Security today responding to Ryan Goodman's recent post exploring what the US's claimed "unwilling or unable" test for self-defence against non-state actors means in the context of Syria and ISIS. Ryan, careful scholar as always, rightly points out that the test "remains controversial under international law." Mike doesn't seem to have any such...

Russia has skillfully managed to devote military support to the separatists in Eastern Ukraine. Just how much support -- and what kind of support -- is unclear, since Russia formally denies that they are directly involved in the ongoing hostilities there. Ukrainian officials have insisted that they have specific proof that Russian troops and their equipment have not only crossed the...

My friend Bobby Chesney has responded at Lawfare to my previous post arguing that Title 50 does not provide the CIA with a public-authority justification to kill Americans overseas. He disagrees with both of the limits on presidential authority to authorise covert action I discussed. I will address the Article II question in a separate post; in this post I want...

As readers are no doubt aware, Libya has descended into absolute chaos. As of now, there is quite literally no functioning central government: Libya’s newly elected parliament has reappointed Abdullah al-Thinni as prime minister, asking him to form a “crisis government” within two weeks even as the authorities acknowledged they had lost control of “most” government buildings in Tripoli. Senior officials and the...

Reasonable people can disagree about the legal merits of U.S. court judgments against Argentina requiring it to pay holdout creditor hedge funds. But I can’t say the same about Argentina’s recently announced claim against the United States at the International Court of Justice. Based on Argentina’s own description of its legal arguments, I stand by my earlier assessment: Argentina’s international...

Last November, I wrote a post entitled "Terrorism Is Dead, and Britain Has Killed It." I chose that title because I couldn't imagine a conception of terrorism more absurd than the one argued by the British government and accepted by a Divisional Court: namely, that David Miranda's mere possession of documents illegally obtained by Edward Snowden qualified as terrorism under the Terrorism Act 2000. I obviously...

[Tamar Meshel is an SJD Candidate at the University of Toronto Faculty of Law.] In the early 1990s, a trend emerged among international legal scholars and practitioners aimed at reviving the Permanent Court of Arbitration (PCA) and, by extension, the use of arbitration to resolve interstate disputes peacefully. The PCA was created during the 1899 Hague Peace Conference, following a century of successful interstate arbitrations such as those between the United States and Great Britain under the Jay Treaty and the Treaty of Ghent, and it reflected the high hopes of the conference participants that the institution would bring about world peace through arbitration. However, after a decade or two of glory, the PCA gradually fell into disuse as states lost interest in arbitration as a dispute resolution mechanism, and it became aptly known as the “Sleeping Beauty of the Peace Palace” (Sam Muller & Wim Mijs, “The Flame Rekindled” (1993) 6(2) Leiden Journal of International Law). There are many political, historical, and legal rationales for this downturn, including the outbreak of the two World Wars, changes in the international political system, and the creation of the PCIJ and ICJ. This post focuses on another development that, while perhaps less recognized, is arguably responsible in part for the decline of interstate arbitrations during the 20th century, and is still relevant today. This development is the gradual ‘judicialization’ or ‘legalization’ of interstate arbitration to the point of being effectively equated with judicial settlement and both its original nature and distinctive qualities becoming imperceptible and inconsequential. The evolution of interstate arbitration The origins of arbitration can be traced back to ancient Greece, where arbitrators were seen as quasi-diplomats rather than judges, and could therefore “consider the equity of the case, whereas a judge is bound by the letter of the law” (Aristotle, cited in M.C.W. Pinto, “The Prospects for International Arbitration: Inter-state Disputes” in A.H.A. Soons, ed, International Arbitration: Past and Prospects (Martinus Nijhoff Publishers, 1990)). Arbitration continued to be used during the Middle Ages to end wars by reconciling the warring parties, and when the modern era of interstate arbitration began with the signing of the 1794 Jay Treaty between Great Britain and the United States, it was perceived as a hybrid process that combined legal proceedings with diplomatic negotiations. For instance, some of the disputes submitted to arbitration under the Jay Treaty were to be decided according to “justice, equity, and the laws of nations”, and their successful settlement was largely credited to the commissioners’ “spirit of negotiation and compromise”. While they rendered binding decisions and applied legal principles, the commissioners also “act[ed] to some extent as negotiators rather than as judges … temper[ed] justice with diplomacy [in order] to give a measure of satisfaction to both sides” (Pinto, 1990). This perception of interstate arbitration persisted in the first decades of the 20th century. Some states, for instance, distinguished between judicial settlement, designed to resolve “legal disputes”, and arbitration, designed to resolve all other disputes ex aequo et bono while “having regard to the general principles of international law” (e.g., the 1928 Geneva General Act for the Pacific Settlement of International Disputes (.pdf); the 1957 European Convention for the Peaceful Settlement of Disputes). Arbitrators were also “prepared to waive a strict application of the law in order to achieve an acceptable settlement” in interstate disputes, such as the 1909 Casablanca case and the 1910 North Atlantic Fisheries case (M.C.W. Pinto, “Structure, Process, Outcome: Thoughts on the ‘Essence’ of International Arbitration” (1993) 6 Leiden Journal of International Law). However, as a result of the growing global quest during the 20th century for “orderly” interstate dispute settlement through the application of law, this quasi-diplomatic use of interstate arbitration gradually fell into disuse, and the dominant perception became that of the International Law Commission, which viewed it as “a procedure for the settlement of disputes between States ... on the basis of law” (Pinto, 1990 (.pdf)). Accordingly, states increasingly restricted or excluded the power of arbitrators to decide disputes on the basis of equity or non-legal considerations and in all but a few rare, yet successful, cases (e.g., the 1968 Rann of Kutch arbitration; the 1986 Guinea-Guinea Bissau arbitration) arbitrators followed suit. The perception that only ‘judicial’ arbitration based on law should be “arbitration properly so called” thus became the conventional wisdom, even though in some cases, such as the 1977 Beagle Channel arbitration, it failed to resolve the parties’ dispute (Pinto, 1990, 1993).

[Priya Urs has recently received a Master of Law (LL.M.) with a specialisation in International Law from the University of Cambridge, U.K.] The recent Whaling in the Antarctic decision of the International Court of Justice (ICJ) has unraveled existing debates about the propriety of whaling today, illustrated by the pivotal determination of whether the Japanese Whale Research Program under Special Permit in the Antarctic (JARPA II) was in line with the object and purpose of the International Convention for the Regulation of Whaling 1946, and what that object and purpose might be. This issue, in turn, raises less discussed questions about the nature of the obligations the Convention imposes on contracting states; specifically, whether it includes an obligation erga omnes to refrain from commercial whaling. In this brief post I describe what the dispute does and does not tell us about the increasingly multilateral quality of state obligations, allowing even non-injured states like Australia to hold others accountable for obligations owed to the international community as a whole. Multilateralism in International Law Australia in its application to the Court alleged that the Japanese Government’s authorization of commercial whaling under the guise of scientific research was a violation of its obligations under international law - the Convention in particular, as well as ‘other obligations’ for the preservation of marine mammals and the marine environment. New Zealand (intervening) went a step further, suggesting that Japan’s actions were a challenge to the system of collective regulation established by the Convention, including contracting parties’ duty of ‘meaningful co-operation’. Japan on the other hand insisted that JARPA II was in line with the treaty’s Article VIII exception for scientific research, also claiming that there exists in customary international law a freedom to engage in whaling. Considered collectively, the tenor of these various arguments raises a larger question about the very nature of state obligations: have multilateral ‘law-making’ treaties become the dominant source of obligations among states in contemporary international law? Professor James Crawford in a recent publication argues that to a large extent, they have. This trend is evident not only from the pleadings of Australia and New Zealand that conservation is a collective interest among states, but from the framework of the Convention itself. The Court’s discussion of the system of regulation set up by the Convention alludes to the cooperative effort among states contemplated during its drafting. In particular, the majority opinion notes the ‘significant role’ accorded to the Whaling Commission in regulating the activities of contracting states. In sum, whether the Convention amounts to a prohibition on or merely the regulation of commercial whaling, its law-making effect is well established. The obvious conclusion to be drawn, then, is that multilateral agreements - such as the present Convention - are not merely aggregations of bilateral relationships. Their multilateral effect is manifested in the interest of states like Australia and New Zealand in ensuring mutual compliance irrespective of their ability to make claims to specific injury arising out of Japan’s violation. As a result, irrespective of whether the Convention was intended to prohibit commercial whaling as a conservationist effort, or simply to regulate states’ access to a common resource, this emphasis by the Court reaffirms this trajectory in the development of international law. Obligations Erga Omnes What is interesting about the proceedings in this dispute, then, is an issue that was not debated at all. Japan made no challenge to Australia’s standing before the Court (only making a challenge to ICJ jurisdiction using Australia’s reservation to the Convention), seemingly accepting as law the proposition that even though Australia was not an injured state in a bilateral relationship with Japan, it had a legal interest in ensuring widespread compliance among contracting states. This conclusion is purely conjecture, yet, regardless of whether this omission was a conscious decision or a glaring mistake by Japan, it is indisputable that all three parties’ positions in the Whaling dispute fall in line with the ICJ’s gradual recognition of obligations erga omnes over the last half-century. Quick to offer an apology for its rejection of Ethiopia and Liberia’s public interest claim against South Africa in the South West Africa Cases, in 1970 the Court in its famous dictum in Barcelona Traction identified obligations erga omnes for the first time as obligations owed to the international community generally. It was only in 2012, however, that the question of standing was addressed by the Court directly, affirming in Obligation to Prosecute or Extradite that all states – including Belgium, a non-injured state – had a legal interest in ensuring Senegal’s compliance with the Convention Against Torture 1984. This trend is reflected most clearly in Article 48 of the ILC’s Articles on the Responsibility of States for Internationally Wrongful Acts 2001 (ARSIWA), a progressive development of the law in which, instead of diluting the definition of an injured state, the ILC ultimately chose to recognise the right of a non-injured state to invoke the responsibility of a state in violation of its international obligations. Though not formally, the ICJ has affirmed the text of Article 48(1)(a) in its 2012 decision in Belgium v Senegal. It is worth noting, however, that the Court indulged Belgium as a complaining state in a situation where the obligations involved were erga omnes partes only. As a result, its position on the broader category of obligations erga omnes in Article 48(1)(b) – owed to the international community as a whole - remains uncertain. It would appear that Article 48(1)(a) might have been similarly applied in the Whaling decision as involving obligations erga omnes partes on the basis of which Australia could defend its standing before the ICJ. Indeed, the Court seems to have subconsciously restricted itself to its position in 2012, determining the whaling dispute entirely on the basis of the Convention and choosing not to address Australia’s claims to Japan’s ‘other obligations’ outside of it.    The ICJ’s silence on these developments in the law of standing in the Whaling decision is perhaps an unfortunate result of Japan’s failure to challenge to Australia’s locus standi. It might have been worthwhile for Japan to have argued that Australia had no legal interest in its alleged non-compliance with its treaty obligations, refuting Australia and New Zealand’s characterization of the dispute as involving multilateral obligations of the sort contemplated by Article 48(1)(a). Conversely, Japan could have taken greater advantage than it did of Australia’s characterization of the Convention as a ‘multilateral regime for the collective management of a common resource’ in its jurisdictional challenge, precluding the need for the ICJ’s resolution of the dispute in the first place. Judges Owada and Bennouna hint at this in their dissenting opinions, each arguing that the self-contained institutional framework created by the Convention should be allowed to take effect in the interest of genuine multilateral cooperation, but stopping short of challenging Australia’s right of standing before the Court. Is it possible to conclude that the ICJ is inclined towards expanding the content of obligations erga omnes to include efforts towards conservation of common resources? While the peremptory norm against torture might have been persuasive in recognizing Belgium’s claim to locus standi in Obligation to Prosecute or Extradite, strictly speaking, the peremptory status of the norm in question is irrelevant to the determination of whether the obligation to adhere to it is erga omnes. Consequently, it would be inaccurate to suggest that the Court in the Whaling decision has recognized the existence of an international norm against whaling.

[Lucas E. Barreiros is a Professor of Public International Law and Coordinator of International Human Rights Law Masters Program at the University of Buenos Aires.] While much attention has been paid to the differences and similarities between the European Court of Human Rights (ECHR) and the Inter-American Court of Human Rights (IACHR) as well as to the dialogue between them [see here, here, here and here for examples], none of that attention has been devoted to comparing the one aspect of their work that best and most synthetically captures all that sets them apart – that is, the doctrines of “margin of appreciation” and “control of conventionality”. It is proposed here that more attention should be paid to the explanatory power of these two doctrines in understanding the different identities and diverging trajectories of the ECHR and the IACHR. As known, the “margin of appreciation” doctrine was developed by the ECHR starting in its Handyside v. United Kingdom judgment. It has been understood to refer, as pointed out by Steven Greer, to “the room for manoeuvre that the Strasbourg institutions are prepared to accord to national authorities in fulfilling their obligations under the European Convention on Human Rights”. The rationale for allowing this margin of appreciation, as pointed out by the ECHR in Handyside when referring to the conditions set out in the Convention to lawfully restrict the freedom of expression, is that national authorities, “by reason of their direct and continuous contact with the vital forces of their countries (…) are in a better position than the international judge to give an opinion on the exact content of these requirements”. For its part, the “control of conventionality” was first mentioned by the IACHR in its judgment in the Case of Almonacid Arellano et al v. Chile.The IACHR held that:
“(…) domestic judges and courts are bound to respect the rule of law, and therefore, they are bound to apply the provisions in force within the legal system. But when a State has ratified an international treaty such as the American Convention, its judges, as part of the State, are also bound by such Convention. This forces them to see that all the effects of the provisions embodied in the Convention are not adversely affected by the enforcement of laws which are contrary to its purpose and that have not had any legal effects since their inception. In other words, the Judiciary must exercise a sort of “conventionality control” between the domestic legal provisions which are applied to specific cases and the American Convention on Human Rights. To perform this task, the Judiciary has to take into account not only the treaty, but also the interpretation thereof made by the Inter-American Court, which is the ultimate interpreter of the American Convention.” (emphasis added).
It should be noted that there are two components to the doctrine – one deals with the responsibility of national authorities to ensure that the application of national legislation does not adversely affect the rights under the American Convention of Human Rights; the other, however, is the direct opposite of the “margin of appreciation” as it leaves no room for national authorities to conduct their own assessment and requires them to apply the interpretation of the IACHR.
