In the summer of 2017, the UN International Law Commission adopted Draft Article 7 and an associated draft annex for its project on immunity of state officials from foreign criminal jurisdiction.Footnote 1 The draft article identifies six “crimes under international law in respect of which immunity ratione materiae shall not apply”: genocide; crimes against humanity; war crimes; crime of apartheid; torture; and enforced disappearance. Given the divergences within the Commission when considering and adopting Draft Article 7 (as evidenced by the plenary debate in 2016 and 2017, the unusual recorded vote on whether to refer the matter to the Commission's drafting committee, and the CommentaryFootnote 2), it is difficult to conclude that the Commission is expressing a view that Draft Article 7 reflects lex lata.
But there is a further reason to doubt its status as lex lata: the lack of state practice—let alone widespread, representative, and consistent state practice Footnote 3—in support of denying immunity for those crimes under customary international law. The lack of practice may be seen by scrutinizing the materials cited in the Commission's commentaryFootnote 4 and in the Fifth Report of the Special RapporteurFootnote 5 that purportedly support each exception. This exercise is difficult because both the Commentary and the Fifth Report aggregate disparate practice into lengthy footnotes that are not targeted to the individual exceptions and that contain references to sources that are not directly germane to the issue at hand (such as citing to civil rather than criminal cases, or citing to national laws on immunity of foreign states rather than of foreign officials).Footnote 6
State Practice in Support of the Six Exceptions
With respect to genocide (Draft Article 7(1)(a)), the Commission's Commentary and the Fifth Report cite to provisions in just six national laws that provide an exception for immunity ratione materiae in national criminal proceedings for this crime.Footnote 7 As a general matter, states have not included exceptions to such immunity in either their general criminal codes or in their legislation implementing the Rome Statute of the International Criminal Court.Footnote 8 Further, the Commission's Commentary and the Fifth Report cite to just one national court caseFootnote 9 and no international court case supporting an exception to immunity ratione materiae in a national criminal proceeding for the crime of genocide. There is no international treaty containing such an exception for the crime of genocide.Footnote 10 Although the Rome Statute is cited in the draft annex to define the crime, the Rome Statute itself is silent on the issue of immunity of a state official from prosecution in a foreign criminal jurisdiction.Footnote 11
With respect to crimes against humanity (Draft Article 7(1)(b)), the Commission's Commentary cites to the same six national laws containing an exception for immunity ratione materiae in national criminal proceedings for such crimes.Footnote 12 Further, it cites to just one national court caseFootnote 13 and to no international court decision supporting such an exception. To the contrary, the ICJ in the Arrest Warrant case indicated circumstances where a former foreign minister might be prosecuted for crimes against humanity, but those circumstances did not include prosecution in a foreign criminal jurisdiction for an official act undertaken while in office.Footnote 14
With respect to war crimes (Draft Article 7(1)(c)), the Commission's Commentary again cites to just six national laws containing an exception for immunity ratione materiae in a national criminal proceeding for war crimes.Footnote 15 It cites to no international court decision and to just four national court cases supporting such an exception, all of which are from European courts.Footnote 16 Here, too, the Arrest Warrant case suggests otherwise, as the foreign minister in that case was also alleged to have committed war crimes.Footnote 17 Further, in the Jurisdictional Immunities of the State case, the ICJ found no exception for war crimes, albeit in the context of state immunity.Footnote 18 There is no international treaty containing an exception to immunity ratione materiae of a state official from foreign criminal jurisdiction for war crimes. The 1949 Geneva Conventions and their Additional Protocols, as well as the Rome Statute, are all silent on this issue.
The crime of apartheid (Draft Article 7(1)(d)), was something of a surprise entry on the list of crimes appearing in Draft Article 7, given that no proposal on this crime was made by the Special Rapporteur in her Fifth Report (rather, it was proposed in the plenary debate and added in the drafting committee). Neither the Commission's Commentary nor the Fifth Report cite to any national law, national case law, or international case law, supporting an exception for immunity ratione materiae in a national criminal proceeding for the crime of apartheid. There is also no international treaty containing such an exception.Footnote 19
With respect to the crime of torture (Draft Article 7(1)(e)), neither the Commission's Commentary nor the Fifth Report cite to any national laws containing an exception to immunity ratione materiae in a national criminal proceeding for the crime of torture. The Commission's commentary cites to just five national court cases supporting such an exception;Footnote 20 of those five cases, two are from the United Kingdom,Footnote 21 two are from the Netherlands,Footnote 22 and one is from Belgium. Neither the Commentary nor the Fifth Report cites to any international court decision supporting such an exception. Although there are no international court cases directly on point, the European Court of Human Rights has indicated that state immunity will not be lifted for civil claims just because torture has been alleged.Footnote 23 There is no international treaty containing such an exception.Footnote 24
For enforced disappearance (Draft Article 7(1)(f)), the Commission's Commentary and the Fifth Report cite to just one national law that denies immunity ratione materiae for allegations of enforced disappearance.Footnote 25 The Fifth Report cites to no national or international case law supporting such an exception. Although there is such an exception in the 1994 Inter-American Convention on Forced Disappearance of Persons,Footnote 26 when states negotiated the 2006 International Convention for the Protection of All Persons from Enforced Disappearance Footnote 27 (which occurred after entry into force of the Rome Statute), the negotiators expressly considered and rejected a proposal Footnote 28 that would deny immunity to state officials.
Reactions by States
In October 2017, forty-nine statesFootnote 29 debated the Commission's work at a meeting of the UN General Assembly's Sixth Committee. Having attended most of the debate, and thereafter reviewed the written statements, my impression is that twenty-three states expressed a largely positive view regarding Draft Article 7(1), although eleven of those states expressed certain reservations, such as the need to link Draft Article 7 with procedural safeguards. By contrast, an almost equal number (twenty-one states) expressed a largely negative view. The remaining five states expressed an ambiguous view. As for whether Draft Article 7(1) reflects existing customary international law, only five states seemed to say that it did, while sixteen states essentially said that it did not. The remaining states did not directly address the point, but twenty-one of the forty-nine states maintained that Draft Article 7(1) was not based on sufficient state practice, while even more (twenty-six of the forty-nine states) expressed reservations or criticism regarding the Commission's method or procedure when adopting the text.
Conclusion
All told, the state practice in support of the six exceptions listed in Draft Article 7 is not widespread, representative, or consistent. Rather than relying on existing practice, the Commission justifies Draft Article 7 on two grounds. First, it claims that there is a “discernible trend” towards limiting such immunity,Footnote 30 a claim that also is not borne out by the extremely limited practice cited. Second, the Commission claims that its draft articles must be shaped to fit “an international legal order whose unity and systemic nature cannot be ignored.”Footnote 31 That vague and cursory claim does not explain how the text of Draft Article 7 takes account of rules that seek to avoid interstate conflict, nor why some crimes are “in” (apartheid) while other crimes are “out” (slavery, trafficking in persons, aggression). What both claims do suggest, however, is that Draft Article 7 is not grounded in law, but in policy-making by the Commission. The divided views within the Sixth Committee appear to suggest the same. In that light, Draft Article 7 might be regarded as a proposal by the Commission for a new rule that could be embodied in a treaty, which states might choose to accept or reject. It cannot be regarded, however, as reflecting existing law.
