Aggression in its essence has been defined as “state conduct that either initiates war against another state or brings about a situation in which the victim is (or may be) driven to war”, see para. 1 of this piece. Up until the early 20th century the waging of war was not prohibited under international law and states could use war as a legitimate political instrument.[1] The Covenant of the League of Nations of 1919 signifies a shift, in which the member states obliged themselves (see article 10 of the Covenant) “to respect and preserve as against external aggression the territorial integrity and existing political independence of all Members of the League.” In the Kellogg-Briand Pact of 1928, war as an instrument of national policy was generally abandoned, see again this piece.
After World War II, the prohibition on the use of force by states was laid down in article 2 (4) of the Charter of the United Nations (UN) which prohibits the threat or use of force against the territorial integrity or political independence of any state. However, two exceptions were made: firstly, individual or collective self-defence by states involving the use of force is authorized by article 51 of the Charter and secondly, the use of force can be authorized by the UN Security Council as under article 42 of the UN Charter.
The aforementioned provisions all relate to state conduct. Therefore, states would be held accountable for a violation. Aggression was first recognized as an international crime resulting in individual criminal liability under international law in the Charter of the International Military Tribunal at Nuremberg (IMT).[2] Its Article 6 (a) gave the IMT jurisdiction over crimes against peace, “namely, planning, preparation, initiation or waging of a war of aggression, or war in violation of international treaties, agreements or assurances, or preparation in a common plan or conspiracy for the accomplishment of any of the foregoing.” This wording is duplicated in article 5 (a) of the Tokyo Charter. The IMT in its judgment of 1946 stated that the crime of aggression “[…] is the supreme international crime differing only from other war crimes in that it contains within itself the accumulated evil of the whole.”
The definition of aggression, as found in article 6 (a) of the IMT, was generally endorsed by the members of the UN General Assembly (GA) in the immediate aftermath of the second World War.[3] However, in the years that followed, the discussions in the UN War Commission showed that there was no overall consensus that there existed a crime of aggression under international law.[4]A step in that direction was taken in 1974 with the UN General Assembly’s adoption of Resolution 3314 (XXIX) on the Definition of Aggression, see p. 7 of this paper. Article 1 of the Annex defines 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, as set out in this Definition.”
Its third article sets out a non-exhaustive list of seven types of acts that would constitute aggression. This includes, among other acts: the invasion or attack by the armed forces of a state of the territory of another state; bombardment by the armed forces of a state on the territory of another state; the act of a state allowing its territory to be used by another state for committing an act of aggression against a third state and the sending of armed bands or mercenaries by a state to commit acts of armed force against another state.
Article 4 of the Annex shows that this list is not exhaustive and that the UN “Security Council may determine that other acts constitute aggression under the provisions of the Charter.”
The definition is not focused on criminal accountability and its primary intention was to guide the Security Council in its decisions on whether a situation amounted to an act of aggression, see para. 14 of this piece. Article 5 (2) of the Annex refers to the war of aggression as a crime against international peace, while stating further that aggression gives rise to international responsibility. Therefore, it made a distinction between an act of aggression short of war and a war of aggression, both activating the general rules of state responsibility but with only the latter leading to individual criminal responsibility, see para. 13 of this piece.
The ad hoc international criminal tribunals, such as the International Criminal Tribunal for the Former Yugoslavia (ICTY) and the International Criminal Tribunal for Rwanda (ICTR), did not have jurisdiction over the crime of aggression, because the circumstances leading to the establishment of these tribunals were largely internal in nature, see p. 9 of this paper.
Article 5 (1) (d) of the Rome Statute of the International Criminal Court (ICC) determines that the ICC will have jurisdiction over the crime of aggression. However, the second paragraph of article 5 sets out that this jurisdiction shall only be exercised once a provision is adopted defining the crime and setting out the conditions under which such jurisdiction shall be exercised. [5]
Seven years after the entry into force of the Rome Statute, a review conference was held in accordance with article 123 to consider amendments, including a definition of the crime of aggression. This review conference was held in Kampala, Uganda from 31 May to 11 June 2010.
Under the new article 8 bis (1) the crime of aggression consists of: “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 an aggression which, by its character, gravity and scale, constitutes a manifest violation of the Charter of the United Nations,” see p. 18 of the RC/Res. 6 Annex I Amendments to the Rome Statute of the International Criminal Court on the Crime of Aggression (11 June 2010).
The article’s second paragraph defines the 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 manner inconsistent with the Charter of the United Nations.” The article then lists the same acts as the UN General Assembly’s resolution 3314 (XXIX) which qualify as acts of aggression, and equates all acts violating article 2 (4) of the UN Charter and Resolution 3314 with a crime of aggression as long as they form a “manifest” violation of the Charter, see p. 14 of this paper.
The crime of aggression is a leadership crime. A suspect must be in a position to “effectively exercise control over or to direct the political or military action of a state.” It has been argued that this excludes non-governmental actors such as organized armed groups involved in armed conflicts and private economic actors.[6]
The Kampala amendments will enter into force for those state parties that have accepted them one year after the deposit of their instrument of ratification or acceptance.[7] For the ICC to actually exercise jurisdiction over the crime of aggression two other conditions need to be fulfilled: firstly, the alleged crime must have occurred more than one year after thirty states have ratified or accepted the amendments, see p. 16 of this paper. Secondly, after 1 January 2017 a decision must be taken by a two-thirds majority of the Assembly of State Parties granting the ICC approval to exercise jurisdiction over the crime of aggression, see pp. 16-17 of the same paper.
When the above mentioned requirements are fulfilled, the jurisdiction of the ICC is ‘activated’. In the situation of a UN Security Council referral, the same procedural conditions are applicable.[8]
However, in the situation where an investigation is started on the basis of the initiative of the Prosecutor (proprio motu) or after referral by a State Party, the procedural conditions for jurisdiction are slightly different.[9] In those cases, the Court may only exercise jurisdiction over an act of aggression committed by a state party, unless that state party has previously made a declaration that it does not accept such jurisdiction.[10] This means that no jurisdiction exists for the crime of aggression with respect to Non-State parties and State parties that have opted-out. In addition, one of the two states involved must have ratified the amendment, see this website.
Moreover, the Prosecutor must ascertain whether the Security Council has made a determination of an act of aggression by the state concerned and notify the UN Secretary-General of the situation before the court.[11] If the Security Council has made such a determination, the Prosecutor may continue the investigations; if not, the Prosecutor may only proceed six months after the date of notification and with the authorization of the Pre-Trial Division of the Court to commence the investigation.[12] With respect to state party or proprio motu referral, it has been argued that the Security Council will, in effect, operate as a preliminary filter mechanism:
Six months after ascertaining inaction by the Council, the Prosecutor will go to the Pre-Trial Division and have to convince four judges to allow him to proceed with the aggression investigation. The Pre-Trial Division will no doubt take judicial notice of, and accord significant evidentiary weight to, the fact that the Security Council declined to either refer the situation itself or to make the necessary aggression determination.[13]
Examples of trials against perpetrators of the crime of aggression can be found in the jurisprudence of the Nuremberg and Tokyo Tribunals. Rudolf Hess was the only Nuremberg defendant who was convicted exclusively on account of crimes against the peace, while 11 other defendants, including Hermann Göring, were sentenced for crimes against peace and traditional war crimes, see para. 3 of this piece. The International Military Tribunal for the Far East convicted 23 defendants, amongst them Hideki Tōjō, for the waging of aggressive war, see para. 4 of the same piece. (For an overview of persons convicted for the crime of aggression, see this website.)
Since 1946 there have been no domestic or international trials for alleged crimes of aggression, although the Security Council has on occasion determined that acts of aggression were committed by for example South Africa and Israel.[14]
With the Kampala amendments to the Rome Statute, new trials for alleged crimes of aggression on a domestic and international level are a possibility. Due to the difficult procedures for prosecuting the crime of aggression and the coming into force of the amendments, some commentators, such as O’Connell, Niyazmatov and Milanovic, however, doubt whether any person will ever be prosecuted for the crime of aggression as defined in the Rome Statute.[15]
