Africa’s contribution towards the development of the International Law Commission (ILC) Draft Articles should not be assessed exclusively on the basis of the limited engagement of African States or individuals in the discursive processes within the ILC, but from a historical perspective. When analysed from that perspective, it becomes clear that Africa has had a long connection to atrocity crimes due to the mass victimization of its civilian populations during the colonial and postcolonial periods and apartheid in South Africa. Following independence in the 1960s, African States played a leading role in the elaboration of legal regimes to deal with international crimes such as apartheid, or in the development of accountability mechanisms to respond to such crimes. Although some of these efforts proved unsuccessful in the end, the normative consensus that was generated went a long way in laying the foundations for the Rome Statute of the International Criminal Court, which, in turn, influenced the conceptual framework of the ILC Draft Articles. This article proposes that given this historical nexus, the substantive provisions and international cooperation framework provided for in the future crimes against humanity convention, Africa has more reasons to support than to oppose it when negotiations begin at the United Nations General Assembly or an international diplomatic conference.

Most post-Soviet States have introduced penal responsibility for crimes against humanity, either explicitly or under alternative headings. As a rule, their respective criminal laws are modelled after relevant provisions of the Draft Code of Crimes against the Peace and Security of Mankind or the Rome Statute of the International Criminal Court. The International Law Commission’s adoption of the Draft Articles on Prevention and Punishment of Crimes Against Humanity represents an appropriate occasion for post-Soviet States that have not yet penalized crimes against humanity to bring their criminal laws into fuller conformity with customary international criminal law.

The Western Europe and Other Group of states have a long history with crimes against humanity. They were pivotal in the juridical creation of this concept, in launching prosecutions in both international and national courts, and in formulating the modern definition of the crime. However, some members have expressed concerns around the International Law Commissions Draft Articles on the Prevention and Punishment of Crimes Against Humanity. This article provides a summary of the history of crimes against humanity in the Western Europe and Other Group of states, as well as the current status of crimes against humanity in their legal systems. It argues that although these states have successfully incorporated crimes against humanity into their legal frameworks, it would be beneficial for them to embrace the proposed Crimes Against Humanity Convention.

No Asian States expressed regret over the failure of the Sixth Committee to reach a consensus on the elaboration of a convention on crimes against humanity. This article examines the comments of Asian States during the Sixth Committee debate on the final Draft Articles submitted by the International Law Commission, demonstrating that most States believed further discussions were needed. It situates these comments against the wider Asian approach to international criminal law, and argues that the concerns of the Asian States during the Sixth Committee are part of a broader context. In doing so, it suggests a common ground for future discussion and the progression of a convention.

The international community has been engaged with the topic of crimes against humanity since the International Law Commission (ILC) began work on it in 2013, with a view to draft articles for a future convention. Between 2013 and 2019, 86 States as well as several entities and subregional groups made comments on the ILC’s work at the United Nations Sixth Committee or through written comments to the ILC. This article is the culmination of the Whitney R. Harris World Law Institute’s work cataloguing and analysing States’ comments by assigning each statement to one of five categories – strong positive, positive, neutral, negative, and strong negative – examining both specific words and the general tenor of the comments. This article analyses the development of States’ reactions to the ILC’s work over time, as well as specific issues that frequently arose, observing that there is a pattern of growing support from States to use the ILC’s Draft Articles on Prevention and Punishment of Crimes Against Humanity as the basis for a new convention.

In a relatively short period of time, the International Law Commission has accomplished the impressive task of drafting and adopting the text of the Draft Articles on Prevention and Punishment of Crimes against Humanity. The Draft Articles circulated to states are promising. However, a number of substantive amendments appear to be necessary if the Draft Convention is to become a powerful tool “to put an end to impunity for the perpetrators of these crimes and thus to contribute to the prevention of such crimes”, as stated in the Preamble. Moreover, in order to avoid the rapid ossification of the new potential treaty, it is advisable for the articles to reflect the most significant developments in international law, and also allow for future progressive developments in the law, instead of reflecting a lowest common denominator acceptable to all states. This article suggests some revisions to existing provisions, new provisions which may make the text much stronger and finally identifies some important omissions which should be fixed by states at the time of adopting the Draft Convention.

Since crimes against humanity were first defined in the Charters of the International Military Tribunals at Nuremberg and for the Far East, various international, hybrid and national institutions have adopted definitions that differ in important respects. The International Law Commission’s draft articles are the latest definition, using language that is almost identical to the definition in the Rome Statute of the International Criminal Court. This article explains that decision, as well as the few divergences between the draft articles and the Statute. Defining crimes against humanity involves balancing the value of respecting state sovereignty against that of protecting human rights, and the values of consistency and clarity against those of breadth and flexibility. It argues that in adopting the draft articles, states will affirm the balance among these values that was struck in Rome, but that both definitions contain sufficient flexibility to permit new balances to be found as global values evolve.

The International Law Commission’s Draft Articles on the Prevention and Punishment of Crimes Against Humanity document is the latest international instrument to address gender-based crimes under international law and the first to do so outside the context of international courts. The elaboration of a treaty on crimes against humanity provides a critical opportunity to affirm that gender-based crimes are among the gravest crimes under international law. This article examines discussions on the meaning of the term ‘gender’ under the ILC’s Draft Articles, with reference to the discussions two decades prior on the definition of ‘gender’ in the Rome Statute of the International Criminal Court, the basis for the Articles’ consideration of sexual and gender-based violence. It then turns to the ILC consultation process, and the 2019 discussion of the ILC’s Draft Articles in the Sixth (Legal) Committee of the United Nations General Assembly on the term ‘gender’. Additionally, it considers a number of concerns raised by States and civil society on the definition of some of the gender-based crimes included in the Draft Articles and concludes by arguing for a comprehensive gender analysis of all of the Draft Articles.

This article values as an important milestone the Draft Articles on the Prevention and Punishment of Crimes Against Humanity. They greatly contribute to the development of international law, inter alia, seeking to prevent impunity and to establish the duty to prosecute or extradite those who have allegedly committed crimes against humanity. They are a solid basis for a possible diplomatic conference designed to adopt a convention that will establish binding obligations for all ratifying States. The Draft Articles took as a point of departure the Rome Statute of the International Criminal Court to list and define crimes against humanity, and, considering current developments in international law, departed from the Rome Statute so far in two matters: the definition of gender and the treatment of persecution. This article argues why it is essential to follow a similar approach and adopt the definition of enforced disappearance currently used in international conventions that deal with such a horrendous crime. The article also shows why the ‘without prejudice’ clause currently proposed by the Draft Articles is unsatisfactory, depriving States that do not follow the restrictive definition incorporated more than two decades ago in the Rome Statute from the benefits of the proposed convention.

The International Law Commission’s Draft Articles on the Prevention and Punishment of Crimes Against Humanity does not include the inchoate crimes of conspiracy or incitement. However, this choice has generated a great deal of academic commentary. This article critically assesses the choice of the drafters to exclude conspiracy and incitement liability, arguing that their decision was flawed. It examines the comments made by academics, as well as participants in the work of the Commission on this draft convention. Additionally, it scrutinizes the methodology employed by the Commission in reaching this conclusion. Finally, it presents a conceptual analysis of the desirability for the inclusion of these two inchoate crimes, arguing that their inclusion would assist in meeting the policy of preventing crimes against humanity.

The International Law Commission’s Draft Articles on the Prevention and Punishment of Crimes Against Humanity contain an obligation to implement an interstate cooperation regime. This article argues that although this regime is ‘horizontal’, it also has the potential to enhance the efficacy of investigations by the International Criminal Court (ICC). It provides a brief overview of the regime as set out in the Draft Articles, and the ICC’s cooperation regime, before exploring how the Draft Articles can fill some gaps in the ICC system. It also makes suggestions to improve the Draft Articles and strengthen the cooperation regime.

The International Law Commission (ILC) Draft Convention on Crimes Against Humanity and the Mutual Legal Assistance (MLA) Initiative have largely run in tandem throughout their development. Both projects are motivated by similar gap-filling desires and both projects aim to expand the international criminal justice toolkit; however, these similarities have led to questions if both projects are necessary. This article addresses that question, looking at how different actors have answered this question during the respective processes of maturation of both projects and where both projects stand today. It argues that, while there is significant overlap between the projects, both instruments have merits which the other is lacking, and the optimal solution would be to bring both projects to fruition.

The International Law Commission, on completion of its work on the draft articles on prevention and punishment of crimes against humanity, recommended to the General Assembly the elaboration of a convention by the said Assembly or by an international conference of plenipotentiaries based on the said draft articles. The Sixth Committee of the United Nations General Assembly at the first opportunity only took note of the draft articles and postponed consideration of the recommendation to its next session. The resolution of the General Assembly, as recommended by the Sixth Committee, does not readily disclose the full extent of the debate, proposals and concerns expressed in the Sixth Committee that prevented the General Assembly from acting on the Commission’s recommendation. This article, in considering the cornucopia of views expressed by States, outlines a path to unlock the Sixth Committee’s potential to act, by proposing a separation of the organizational and substantive matters and future-proofing the further consideration of elaborating a convention through the adoption of a structured approach.

In 2019, the International Law Commission (ILC) adopted its articles on the prevention and punishment of crimes against humanity and referred them to the UN General Assembly with the recommendation of adopting a multilateral treaty based on them. The General Assembly’s Sixth Committee was unable to take a decision on this matter and deferred its consideration to 2020. This article focuses on how, in resuming its discussion, the Sixth Committee will have a unique opportunity to define the process towards intergovernmental negotiations. This will close a gap in international criminal law, while generating a new dynamic in its relationship with the ILC on codification, breaking its current cyclical inertia of inaction.
