The First Review Conference of the Rome Statute of the International Criminal Court
Twelve years ago this summer, hundreds of delegationsâfrom governments, non-governmental organizations, international organizations and elsewhereâcheered the establishment of the first permanent international criminal court in Rome. At the time, Rome Conference Chairman Philippe Kirsch exulted to the Conference newspaper, Terraviva: "This is an extraordinary moment, a historical moment. I am not sure to what extent those present here know how important this is for the future of humankind." Much has happened in the years since Rome to clarify the significance of that moment. The Rome Statute of the International Criminal Court (ICC) entered into force in 2002. The ICC has become a fully operational tribunal, seeking the arrests of individuals from Uganda, the Democratic Republic of Congo, Sudan and the Central African Republic, launching an investigation in Kenya, examining other situations and beginning three trials. It not only seeks to hold accountable those it accuses of war crimes, crimes against humanity, and genocide; it has become an actor in domestic and international politics, in the countries where it pursues cases and in those countries that are non-States Parties anxious about the reach of its jurisdiction.
From May 30th to June 11th, the 111 States Parties to the Rome Statuteâalong with observer delegations from non-States Parties, NGOs, civil society, and othersâwill have an opportunity to assess the development of the ICC over the past decade when they gather in Kampala, Uganda, to hold their first Review Conference. While the Conference will take stock of the progress of the Court in a variety of areas and consider a handful of proposals on other matters, the negotiation of an amendment to add aggression as a crime under ICC jurisdiction promises to overshadow all else. At the same time, the United States will participate as an observer, bringing to Kampala not only a new level of American engagement and support but also strong opposition to any resolution of the aggression issue that fails to give the United Nations Security Council a pivotal role. All the while, the absence from the Courtâs detention facility in The Hague of several high-profile accused individualsâsuch as Sudanâs President Omar Hasan al-Bashir and the Ugandan Lordâs Resistance Armyâs Josephy Konyâwill serve as a reminder that States Parties still have some distance to go before the Court operates as a credible response to mass atrocities.
This Insight takes an advance look at key issues on the agenda at Kampala.
Under the Rome Statute, the ICC may now exercise jurisdiction over three categories of crimes: genocide, crimes against humanity, and war crimes. The Court may not exercise jurisdiction over a fourth crime, aggression, until the State Parties adopt a provision "defining the crime and setting out the conditions under which the Court shall exercise jurisdiction with respect to this crime."
Aggression has a distinguished pedigree in international law, principally dating from the immediate aftermath of World War II. The United Nations Charter grants the Security Council the power to determine the occurrence of an act of aggression. While the General Assembly adopted a Definition of Aggression in 1974, the Security Council itself has never defined the term. The Charter of the International Military Tribunal (IMT) at Nuremberg designated a "war of aggression" as a crime against peace, while the IMT for the Far East, the Tokyo Tribunal, similarly defined as a crime against peace "a declared or undeclared war of aggression." Both the Nuremberg and Tokyo Tribunals convicted several high-ranking German and Japanese leaders, respectively, of the crime of aggression (and acquitted several others). Since that time, a number of international instruments have restated the criminality of aggression. However, the international criminal tribunals since Nuremberg and Tokyo have not followed their steps, instead possessing jurisdiction only over war crimes, crimes against humanity, and genocide.
Notwithstanding its place in the post-war pantheon of international crimes, aggression was among the key controversies at the Rome Conference in 1998, and participants in Rome were unable to reach agreement on its definition or the mechanism to trigger the Courtâs jurisdiction. Since 2002, States Parties and others (including non-party governments and NGOs) participated in a working group (known as the "Princeton Process") to develop a consensus definition of aggression and the conditions under which the Court may exercise jurisdiction. Several prominent non-States Parties, including China, participated in these discussions; however, the Bush Administration decided that the United States would not participate. In the absence of the United States, participants achieved a definition for which a consensus has seemingly emerged. However, they failed to achieve consensus with respect to jurisdiction.
The proposed definition provides a substantive legal definition of the crime of aggression as
the planning, preparation, initiation or execution, by a person in a position effectively to exercise control over or to direct the political or military action of a State, of an act of aggression which, by its character, gravity and scale, constitutes a manifest violation of the Charter of the United Nations.
The proposal defines an act of aggression as "the use of armed force by a State against the sovereignty, territorial integrity or political independence of another State, or in any other manner inconsistent with the Charter of the United Nations." Modeled on the UN General Assemblyâs 1974 Definition of Aggression, the proposal provides a list of seven acts that qualify as acts of aggression.
The proposal is arguably consistent with contemporary understandings of the jus ad bellum. Yet much remains open to interpretation. For instance, how serious must an act of aggression be to merit ICC attention? To what extent would humanitarian justifications of force, such as those envisaged by the Responsibility to Protect, be taken into account by the Court? Would the Court consider the examples of aggressive force illustrative or exhaustive?
Jurisdiction presents a much more serious obstacle to adoption of an aggression amendment. States and NGOs broadly agree that the Court could exercise jurisdiction where the Security Council has already determined an act of aggression (assuming all other elements required for jurisdiction are met). They differ over whether such a determination should be required before the Court may open an investigation, as the permanent Security Council members desire. The Review Conference will need to determine whether a Security Council trigger is required or whether other mechanismsâsuch as the Prosecutorâs independent powers or a General Assembly referralâmight enable the initiation of an investigation.
One alternative to the Security Council requirement would be to require the "aggressor State" to consent to ICC jurisdiction, which would achieve the functional equivalent of a Security Council trigger for the Councilâs permanent members (assuming they would not provide such consent). Still, a large plurality of States Parties oppose such a requirement. A poll of States Parties during the March resumed session of the Assembly of States Parties (ASP) indicated continued lack of consensus, with the vast majority of delegations opposing the Security Council requirement.
The Obama administration clearly is anxious about the Kampala outcome; it undoubtedly wishes to support the ICC, but a negative outcome on aggression (from its perspective) could conceivably undermine such engagement. The U.S. Ambassador at Large for War Crimes Issues, Stephen J. Rapp, told the ASP in November in The Hague that "[o]ur view has been and remains that . . . jurisdiction should follow a Security Council determination that aggression has occurred." State Department Legal Adviser Harold Koh amplified this position in March, indicating that the Obama Administration strongly favors the requirement of a Security Council trigger and casting doubt on the compatibility of the definition with customary international law. France and the United Kingdomâthe two permanent Security Council members that are parties to the Rome Statuteâshare the U.S. jurisdictional concerns, but whether they can find a creative solution that meets everyoneâs needs remains to be seen.
After several years of negotiations, States Parties have found resolution of the jurisdictional issues to be elusive. In this light, it may well be that the Review Conference will fail to conclude the aggression negotiations. One possibility might involve a piecemeal approach: the adoption of a definition but the deferral of the negotiations over jurisdiction, thereby keeping aggression out of the ICC until some later negotiation. It is uncertain whether such an approach would be acceptable to those States strongly supportive of adding the crime of aggression to the Rome Statute.
The War Crimes Opt-out
Article 124 of the Rome Statute enables a party to opt out of the war crimes jurisdiction of the Court (Article 8) for an initial period of seven years after the entry into force of the Statute for that party. It also mandates a review of the opt-out by the Review Conference. France strongly sought this provision in Rome in 1998, but it withdrew its opt-out declaration in 2008. Colombia is the only other country to have exercised the opt-out, but its declaration expired this fall. The opt-out was highly controversial in Rome, but its impact has been minimal. Given the limited use of the provision, State Parties will have difficulty arguing that retaining Article 124 will entice non-parties to ratify the Rome Statute. Thus far, States Parties acknowledge the limited value of Article 124, but whether a consensus in favor of its deletion has emerged remains unclear.
States Parties have proposed a number of amendments to the Rome Statute. Mexico proposed the criminalization of the use or threat of use of nuclear weapons. The Netherlands proposed a new Rome Statute crime of terrorism. Norway proposed new language to deal with the enforcement of sentences. Trinidad and Tobago proposed jurisdiction over drug offenses. South Africa and the African Union, reflecting their opposition to the arrest warrant for Sudanese President al-Bashir, proposed amending Article 16 to make it easier for outside parties to seek the deferral of a case pending before the Court. None of these amendments will be subject to formal discussion at the Review Conference, as the ASP decided to establish working groups to develop each of these proposals at subsequent meetings of States Parties.
One proposal by Belgium will be considered by the Review Conference. The proposal would extend the criminalization in international armed conflict of three existing categories of weapons â poison and poisoned weapons, gases, and certain kinds of long-prohibited bullets â to non-international armed conflict. The proposal has received broad support among States Parties but very little substantive discussion; unless serious concerns are raised, it should be a strong candidate for adoption in Kampala.
In addition to the treaty-based work, the Review Conference will hold a number of "stocktaking" sessions. As currently conceived, the exercise will involve a review of the complementarity regime, the Statutory mechanism by which the Court defers to ongoing investigations and prosecutions in domestic tribunals; cooperation with the Court; the ICCâs impact on victims and affected communities; and the interaction of "peace and justice." The sessions will be designed around keynotes and panels of experts on the four topics. Although it is difficult to predict, it seems unlikely that the stocktaking exercise will amount to a probing review of the ICCâs strengths and weaknesses in these areas and lead to concrete recommendations and proposals.
The ICC Review Conference is likely to involve hard work (especially on the definition of aggression), workaday treaty considerations (focusing on the war crimes opt-out and the Belgian proposal), and assessment (stocktaking). Amidst this busy schedule, the Court, States Parties, and NGOs should not shy away from critically reflecting on what the Court has done right and wrong over the past several years. The Review Conference provides an important moment to examine the Courtâs performance to ensure that it is fulfilling objectives established more than a decade ago.
The Review Conference, of course, also presents an opportunity for the United States to take stock of its own relationship to the Court. The Obama administration has already advanced the relationship with a concrete proposal to meet with the chief prosecutor to find where it might make contributions. The aggression negotiations, however, guarantee that the new relationship will have elements of disharmony, as U.S. Government representatives will likely push hard for a required Security Council trigger. The administration will face pressure in Washington to step away from a new era of cooperation with the Court if the aggression negotiations lead to a bad result from the U.S. perspective. In that sense, the stakes in Kampala are high, providing a key test not only for U.S. policy but for the future of the institution and international justice.
