When the contracting parties to the Rome Statute establishing the International Criminal Court met in Kampala in 2010 to discuss possible amendments to the statute, the main focus was, and has thereafter remained, on the crime of aggression. In addition to amending the statute to include the crime of aggression, however, the contracting parties amended Article 8 of the statute to include a broader range of war crimes in noninternational armed conflicts over which the ICC can have jurisdiction—inter alia, by including the use of chemical weapons. Although the latter amendment received much less attention from both the Kampala drafters and outside observers than the former, it is the use of chemical weapons that has come most quickly into play in world events. In particular, the use of chemical weapons by Syrian government forces in 2013 (and perhaps subsequently) has acutely raised questions concerning the extent of the ICC’s treaty-based jurisdiction, both under the unamended text of the Rome Statute or in situations where the amendment to Article 8 applies. These events have also provoked consideration concerning the Security Council’s legal powers to extend the ICC’s jurisdiction to certain crimes involving chemical weapons that would otherwise be beyond its subject matter jurisdiction. These questions are considered in this Note.

44 Id., Amend. 2. This latter proposal was cosponsored by only fourteen states: Argentina, Belgium, Bolivia, Burundi, Cambodia, Cyprus, Ireland, Latvia, Luxembourg, Mauritius, Mexico, Romania, Samoa, and Slovenia. see ICC-ASP/8/43/Add.1, supra note 41, at 3–4.

46 The respective part of the Elements of Crimes (namely, element 2) relating to both Article 8(2)(e)(xiii) (“War crime of employing poison or poisoned weapons”) and (xiv) (“War crime of employing prohibited gases, liquids, materials or devices”), as adopted in Kampala, requires in identical terms that “[t]he substance was such that it causes death or serious damage to health in the ordinary course of events, through its [additional for Article 8(2)(e)(xiv): asphyxiating or] toxic properties.” Res. RC/Res.5, supra note 3, Annex II. The one difference is that the elements relating to Article 8(2)(e)(xiv) contain, in a footnote, a disclaimer providing that “[n]othing in this element shall be interpreted as limiting or prejudicing in any way existing or developing rules of International Law with respect to the development, production, stockpiling and use of chemical weapons.” Id., n.1.

56 Given that the Security Council was not acting under Chapter VII when it adopted Resolution 2118, it could have not referred the situation to the ICC anyway. But see the statements made by Luxemburg, UN SCOR, 68th Sess., 7038th mtg., UN Doc. S/PV.7038, at 7 (Sept. 27, 2013) (“The time has come to finally refer the situation in Syria to the International Criminal Court.”) Australia, id. at 15 (“Australia’s assessment is that the evidence available shows that it was the Syrian authorities who were responsible for this crime, and this incident has confirmed what Australia has said for a long time—that the Council should refer the situation in Syria to the International Criminal Court.”).
57 On January 14, 2013, Switzerland had sent a letter to the Security Council on behalf of fifty-eight countries urging the council to refer the situation in Syria to the ICC. see Letter Dated 14 January 2013 from the Charge d’Affaires A.I. of the Permanent Mission of Switzerland to the United Nations Addressed to the President of the Security Council, UN Doc. S/2013/19. See also the conclusions that the European Union Foreign Affairs Council adopted in December 2012 calling on the Security Council to refer the situation in Syria to the ICC.

61 Id.,para. 15 (“refer[ring] the situation in Syria since 1 March 2011 to the Prosecutor of the International Criminal Court”). The resolution would have been mutatis mutandis identical to the two previous Security Council resolutions referring situations to the ICC—namely, Resolution 1593 (Mar. 31, 2005) (Sudan) and Resolution 1970 (Feb. 26, 2011) (Libya).
62 The Syrian Arab Republic signed the Rome Statute on November 29, 2000, and unlike other states such as Israel, Sudan, and the United States, it has not indicated its intention not to ratify it. see UN Treaty Collection, Rome Statute of the International Criminal Court, at http://treaties.un.org/pages/ViewDetails.aspx?src=TREATY&mtdsg_no=XVIII-10&chapter=18&lang=en.

68 This argument is consistent with the terms of the May 2014 Security Council draft resolution to refer violations of international humanitarian law committed in the course of the conflict in Syria (since March 2011) to the ICC prosecutor. see UN Doc. S/2014/348 (May 22, 2014). Unlike the French draft resolution of September 13, 2013, this draft resolution did not contain a specific reference to the use of chemical weapons. This May 2014 draft resolution, while receiving thirteen votes in favor, was not adopted; China and the Russian Federation were opposed. see Referral of Syria to International Criminal Court Fails as Negative Votes Prevent Security Council from Adopting Draft Resolution, UN Doc. SC/11407 (May 22, 2014), at http://wwyw.un.org/News/Press/docs/2014/sc11407.doc.htm. In the context of that discussion, the U.S. representative did make reference to the use of chemical weapons and indicate that such crimes, if proven, ought to be punished by the ICC. UN Doc.
