Explanatory Memorandum to the Act regarding the Amendments of 10 and 11 June 2010 to the Rome Statute of the International Criminal Court of 17 July 1998

- Germany -


Overall assessment

From 31 May to 11 June 2010, the first Review Conference of the Rome Statute of the International Criminal Court took place in Kampala (Uganda). A central endeavour of that conference was to achieve agreement in relation to the crime of aggression. Following intense discussions and negotiations, the States Parties to the Rome Statute agreed on 11 June 2010 on a definition of the crime of aggression and on the conditions under which the Court may exercise jurisdiction with respect to that crime.

The agreement reached in Kampala constitutes a historical breakthrough in the development of international criminal law. The insertion of a definition of the crime of aggression in the Rome Statute closes a major gap in international criminal law and marks an important step in the fight against impunity for perpetrators of the most serious crimes of concern to the international community as a whole. The agreement on the crime of aggression results from a compromise achieved with some considerable effort between the States Parties and follows many years of preparatory discussions. The Federal Republic of Germany played an important role in this process and in shaping the compromise.

In addition, the Review Conference resolved on 10 June 2010 to amend article 8 of the Rome Statute and to add certain acts, already regarded as war crimes when committed in international armed conflict, as offences also in the context of armed conflicts not of an international character.

The States Parties to the Rome Statute agreed the amendments in two resolutions adopted by consensus on 10 and 11 June 2010. The German translation of the two resolutions is attached as an annex.

Definition of the crime of aggression and the Court's exercise of jurisdiction

Background to the issue

In the trials held before the International Military Tribunals in Nuremberg and Tokyo, the crime of aggression - expressed as crimes against peace - constituted one of the central prosecution charges. Article 6 (a) of the Charter of the Nuremberg Military Tribunal, which criminalized the 'planning, preparation, initiation or waging of a war of aggression, or a war in violation of international treaties, agreements or assurances was based on the Kellogg-Briand Pact of 1928 which required Contracting States to refrain from wars and acts of aggression. However, following the Nuremberg and Tokyo trials, it proved extremely difficult to codify the offence described by the International Military Tribunal in Nuremberg as the 'supreme international crime'.

The notion of aggression was addressed in resolution 3314 (XXIX) of the United Nations General Assembly of 14 December 1974. However, as a political document, its definition of aggression was not drafted for the purposes of international criminal law but to assist the United Nations Security Council in determining the existence of an act of aggression within the meaning of article 39 of the UN Charter.

Admittedly, the Rome Statute of the International Criminal Court adopted on 17 July 1998 at the Conference of Diplomatic Plenipotentiaries in Rome, which entered into force for the Federal Republic of Germany on 1 July 2002 (BGBl. 2003 II p. 293), included the crime of aggression alongside the crime of genocide, crimes against humanity and war crimes in article 5 (1) which lists the crimes within the jurisdiction of the International Criminal Court (ICC). However, in contrast to the situation regarding the first three crimes, no agreement could be reached in Rome on the definition of the crime of aggression and on the conditions under which the Court may exercise jurisdiction with respect to that crime. In particular, there was disagreement on the role the United Nations Security Council should play in determining whether an act of aggression exists. For that reason, article 5 (2) of the Rome Statute expressly provided that exercise of jurisdiction by the ICC over the crime of aggression was conditional on a subsequent agreement between the States Parties defining the crime and setting out the conditions under which the Court could exercise jurisdiction with respect to that crime. The Final Act of the Rome Conference provided for the establishment of a commission to prepare proposals on matters that were unresolved and to submit such to the Assembly of the States Parties to the Rome Statute.

This task was initially entrusted to the Preparatory Commission for the ICC which met from spring 1999 to summer 2002. In turn, the Commission established a Working Group on the Crime of Aggression which summarized the most important positions on the crime of aggression in a discussion paper of 11 July 2002. Following the entry into force of the Rome Statute in July 2002, the Assembly of the States Parties to the Rome Statute convened a Special Working Group on the Crime of Aggression to continue and complete the work on the crime of aggression. The deliberations of this Special Working Group, which met from September 2003 to February 2009 and were supplemented by informal meetings at the Liechtenstein Institute on Self-Determination in the Woodrow Wilson School of Public and International Affairs at Princeton University, were characterised by comprehensive dialogue and the greatest possible transparency. Consultations and discussions involved not only the States Parties to the Rome Statute but also non-States Parties and representatives from academia and nongovernmental organizations on behalf of civil society at large. The publication of detailed reports on the work of the Special Working Group after every meeting facilitated the continuation and strengthening of the dialogue with civil society and academia in between the meetings. The Special Working Group presented its proposals to the Assembly of the States Parties on 13 February 2009, which, in turn, accepted these unanimously on 26 November 2009. The proposals set out a provisional agreement as regards the definition of the crime of aggression but certain matters remained unresolved in relation to the exercise of the Court's jurisdiction. These proposals provided the basis for the negotiations at the Review Conference in Kampala.

Developments at the Conference

Given the preparatory work of the Special Working Group in the years preceding the Conference and the agreement reached in that context on the definition of the crime of aggression, negotiations in Kampala were focused on formulating the conditions under which the Court may exercise jurisdiction with respect to that crime. The delegations sought if at all possible to achieve agreement by consensus.

The key issues for the negotiations were, first, the role of the United Nations Security Council and, second, the conditions under which the new provision should enter into force. As regards the Security Council, certain States including the permanent members of the Security Council argued that article 39 of the UN Charter conferred on the Security Council a central role in the determination of the existence of an act of aggression. Consequently, in their view, the ICC could only have jurisdiction over the crime of aggression following a referral by the Security Council as, in relation to that crime, it was argued, the sole mechanism for triggering the Court's jurisdiction should be the mechanism provided for in article 13 (b) of the Rome Statute. Other States including the Federal Republic of Germany argued that the ICC should have jurisdiction in relation to the crime of aggression not only in the case of a referral by the Security Council but also in the other cases provided for in article 13 of the Rome Statute, that is, in the case of a referral by a State Party and in the case of an investigation initiated proprio motu by the Prosecutor. Ultimately, this latter view prevailed at the Kampala Conference.

As regards the ratification procedure to be followed in this matter, there was disagreement whether the procedure provided for in article 121 (4) or that of article 121 (5) of the Rome Statute should apply. Here, the Conference ultimately decided to adopt the latter procedure.

The fact that these decisions - by which the German objectives for the Conference were achieved in full - were adopted by consensus must be seen as a success in international law terms. This outcome was only possible through its incorporation in a compromise package which also

  • established a quorum of ratifications by thirty States Parties before the Court may exercise jurisdiction in this regard,
  • required a decision by the Assembly of the States Parties confirming the Court's authority to exercise jurisdiction with respect to this crime to be taken after 1 January 2017, and
  • introduced the option for a State Party to exclude the exercise of jurisdiction by the Court in this regard in the case of referrals by States Parties and investigations proprio motu by the Prosecutor.

Results of the negotiations

Definition of the crime of aggression
(article 8bis of the Rome Statute)

The definition of the crime of aggression adopted at the Review Conference constitutes a careful compromise and takes account of the fact that this crime -by reason of its criminalization of State acts of aggression and because of the leadership requirement - has a special character in contrast to the other crimes referred to in the Rome Statute.

The definition of the individual elements of the crime follows almost word for word the definition of 'crimes against peace' established in the Charter of the Nuremberg Military Tribunal. To counter the risk that this definition of the crime could be politicized, first, the definition of what constitutes an 'act of aggression' follows word for word the Definition of Aggression annexed to resolution 3314 (XXIX) of the United Nations General Assembly of 14 December 1974 and, second, the existence of an act of aggression itself does not give rise to the crime of aggression. Instead, the act of aggression must 'by its character, gravity and scale, constitute a manifest violation of the Charter of the United Nations'. Consequently, not every use of force by States which is contrary to international law will constitute also a crime of aggression. The provision is intended specifically not to include and hence not to criminalize as a crime of aggression actions whose legality is disputed - such as those committed in the course of humanitarian interventions - and situations in which the aggression is not of sufficient severity.

The crime of aggression is a leadership crime which can only be committed - be it as principal or accessory - by a narrowly defined set of perpetrators. Only persons in a position effectively to exercise control over or to direct the political or military action of a State can be held individually responsible.

Exercise of jurisdiction over the crime of aggression
(article 15bis and article 15ter of the Rome Statute)

Following intense negotiations, the scheme adopted concerning the exercise of the Court's jurisdiction in relation to the crime of aggression provides that all three mechanisms set out in article 13 of the Rome Statute, by which the Court's jurisdiction is triggered for the other crimes covered by the Rome Statute (the crime of genocide, crimes against humanity and war crimes), shall apply also to the crime of aggression.

Pursuant to the new article 15bis, the Court shall have jurisdiction either as a result of State referral or on the initiative of the Prosecutor (proprio motu). In neither case is there any need for a prior determination by the Security Council of an act of aggression by a State. However, the jurisdiction of the ICC over the crime of aggression under this article is restricted in two respects. First, the ICC has no jurisdiction over the crime where it is committed by the national of a non-State Party or on the territory of such a State. Second, States Parties are able to exclude by declaration the jurisdiction of the ICC over the crime of aggression (also known as 'opting out'). The special role played by the Security Council in ensuring world peace and restoring international security is underlined by procedural rules establishing a scheme of cooperation between the ICC and the Security Council.

In recognition of the special role played by the Security Council in the determination of an act of aggression, referral by the Security Council of a situation of that kind to the ICC is governed by a separate article, the future article 15ter of the Rome Statute. States Parties to the Rome Statute and non-States Parties can be the subject of a referral by the Security Council. In addition, in this case, States cannot opt out of the jurisdiction of the ICC in relation to the crime of aggression.

Activation of the ICC's jurisdiction over the crime of aggression

Before the ICC can exercise any jurisdiction over the crime of aggression the following conditions must be satisfied. First, the amendments to the Rome Statute must have been ratified or accepted by thirty States Parties. Second, the Court's jurisdiction over the crime of aggression must have been confirmed by a decision of the Assembly of States Parties. This decision cannot be taken until after 1 January 2017. This requirement constitutes an important element of the compromise package achieved in Kampala.

Amendment to article 8 of the Rome Statute

In addition to reaching agreement on the crime of aggression, the Review Conference in Kampala adopted an amendment to article 8 (2) (e) of the Rome Statute in relation to war crimes. As a result of this amendment, the deployment of certain weapons and bullets, which already constitutes a war crime when it occurs in international armed conflict, is now also a war crime when effected in armed conflict not of an international character, thus reflecting the position under customary international law and the German Code of Crimes Against International Law (Völkerstrafgesetzbuch). In 1998 the United Nations Diplomatic Conference of Plenipotentiaries in Rome had discussed an alignment of the offences constituting war crimes in international armed conflict and armed conflict not of an international character for the purposes of article 8 of the Rome Statute. However, at the time, no agreement could be reached.

The amendments result from a Belgian initiative, first proposed at the annual Assembly of States Parties in 2008. The draft resolution amending article 8 initiated by Belgium and supported by Germany and seventeen other States proved not to be controversial at the Kampala Review Conference and was adopted by consensus.

Elements of Crimes and understandings regarding the amendments

Together with the amendments made to the Rome Statute by resolution 5 of 10 June 2010 on article 8 (2) (e) (xiii), (xiv) and (xv) and resolution 6 of 11 June 2010 on article 8bis, amendments were also made to the Elements of Crimes, which, pursuant to article 9 of the Rome Statute, are intended to assist the ICC in the interpretation and application of the definitions of the crimes.

As a further aid to interpretation, the Conference adopted in resolution 6 understandings regarding the amendments to the Rome Statute of the International Criminal Court on the crime of aggression.

The German translations of the Elements of Crimes and the understandings regarding the amendments are included in the resolutions annexed to this explanatory memorandum.

German translation

The German translation of the amendments was produced jointly by official representatives of the Federal Republic of Germany, the Republic of Austria, the Swiss Confederation and the Principality of Liechtenstein on the basis of a draft produced by the Federal Republic of Germany.

Resolution RC/Res.5

Adopted at the 12th plenary meeting, on 10 June 2010, by consensus

RC/Res.5 Amendments to article 8 of the Rome Statute

The Review Conference,

Noting article 123, paragraph 1, of the Rome Statute of the International Criminal Court which requests the Secretary-General of the United Nations to convene a Review Conference to consider any amendments to the Statute seven years after its entry into force,

Noting article 121, paragraph 5, of the Statute which states that any amendment to articles 5, 6, 7 and 8 of the Statute shall enter into force for those States Parties which have accepted the amendment one year after the deposit of their instruments of ratification or acceptance and that in respect of a State Party which has not accepted the amendment, the Court shall not exercise its jurisdiction regarding the crime covered by the amendment when committed by that State Party's nationals or on its territory, and confirming its understanding that in respect to this amendment the same principle that applies in respect of a State Party which has not accepted the amendment applies also in respect of States that are not parties to the Statute,

Confirming that, in light of the provision of article 40, paragraph 5, of the Vienna Convention on the Law of Treaties, States that subsequently become States Parties to the Statute will be allowed to decide whether to accept the amendment contained in this resolution at the time of ratification, acceptance or approval of, or accession to the Statute,

Noting article 9 of the Statute on the Elements of Crimes which states that such Elements shall assist the Court in the interpretation and application of the provisions of the crimes within its jurisdiction,

Taking due account of the fact that the crimes of employing poison or poisoned weapons; of employing asphyxiating, poisonous or other gases, and all analogous liquids, materials or devices; and of employing bullets which expand or flatten easily in the human body, such as bullets with a hard envelope which does not entirely cover the core or is pierced with incisions, already fall within the jurisdiction of the Court under article 8 (2) (b) as serious violations of the laws and customs applicable in international armed conflict,

Noting the relevant elements of the crimes within the Elements of Crimes already adopted by the Assembly of States Parties on 9 September 2000,

Considering that the abovementioned relevant elements of the crimes can also help in their interpretation and application in armed conflict not of an international character, in that inter alia they specify that the conduct took place in the context of and was associated with an armed conflict, which consequently confirm the exclusion from the Court's jurisdiction of law enforcement situations,

Considering that the crimes referred to in article 8 (2) (e) (xiii) (employing poison or poisoned weapons) and in article 8 (2) (e) (xiv) (asphyxiating, poisonous or other gases, and all analogous liquids, materials and devices) are serious violations of the laws and customs applicable in armed conflict not of an international character, as reflected in customary international law,

Considering that the crime referred to in article 8 (2) (e) (xv) (employing bullets which expand or flatten easily in the human body), is also a serious violation of the laws and customs applicable in armed conflict not of an international character, and understanding that the crime is committed only if the perpetrator employs the bullets to uselessly aggravate suffering or the wounding effect upon the target of such bullets, as reflected in customary international law,

Decides to adopt the amendment to article 8 (2) (e) of the Rome Statute of the International Criminal Court contained in annex I to the present resolution, which is subject to ratification or acceptance and shall enter into force in accordance with article 121 (5) of the Statute;

Decides to adopt the relevant elements to be added to the Elements of Crimes, as contained in annex II to the present resolution.

Referrals by the Security Council

1. It is understood that the Court may exercise jurisdiction on the basis of a Security Council referral in accordance with article 13, paragraph (b), of the Statute only with respect to crimes of aggression committed after a decision in accordance with article 15ter, paragraph 3, is taken, and one year after the ratification or acceptance of the amendments by thirty States Parties, whichever is later.

Domestic jurisdiction over the crime of aggression

4. It is understood that the amendments that address the definition of the act of aggression and the crime of aggression do so for the purpose of this Statute only.

Other understandings

6. It is understood that aggression is the most serious and dangerous form of the illegal use of force; and that a determination whether an act of aggression has been committed requires consideration of all the circumstances of each particular case, including the gravity of the acts concerned and their consequences, in accordance with the Charter of the United Nations.

7. It is understood that in establishing whether an act of aggression constitutes a manifest violation of the Charter of the United Nations, the three components of character, gravity and scale must be sufficient to justify a "manifest" determination. No one component can be significant enough to satisfy the manifest standard by itself.
