Draft – editorial review pending. As of 27 September 2026.

The Rome Statute establishes the International Criminal Court (ICC) with jurisdiction over genocide, crimes against humanity, war crimes and the crime of aggression. Art. 8 bis, adopted at the 2010 Kampala Review Conference, defines the crime of aggression as a leadership crime based on a State “act of aggression” that constitutes a manifest violation of the UN Charter. The Statute contains no provision specific to cyber operations. The ICC Office of the Prosecutor (OTP) has issued a policy stating that the Statute applies to conduct committed or facilitated through cyber means. Art. 8 bis is referred to in debates on whether and when cyber operations may amount to an act of aggression and on individual criminal responsibility for such conduct.

• Art. 8 bis(1) – The “crime of aggression” means 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.
• Art. 8 bis(2) – An “act of aggression” is 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 UN Charter; the provision lists acts drawn from UN General Assembly resolution 3314 (XXIX) of 1974.
• Arts 15 bis and 15 ter – Conditions for the exercise of jurisdiction over the crime of aggression (State referral / proprio motu; Security Council referral), including exclusion of nationals and territory of non-States parties in the former case.
• Art. 8(2) – War crimes, including attacks against civilians and civilian objects, which may be committed through cyber means.
• Art. 25(3)(e) – In respect of genocide, direct and public incitement to commit genocide.
• Art. 70 – Offences against the administration of justice (e.g. interference with witnesses or evidence).

OTP policy. The OTP released a draft Policy on Cyber-enabled Crimes under the Rome Statute for public consultation on 6 March 2025 (consultation until 30 May 2025) and launched the final policy on 3 December 2025. The policy states that the Statute applies to conduct that takes place in cyberspace and addresses genocide, crimes against humanity, war crimes, the crime of aggression and Art. 70 offences committed or facilitated through cyber means, as well as questions of digital evidence. The OTP had earlier stated that, in appropriate circumstances, conduct in cyberspace may potentially amount to war crimes, crimes against humanity, genocide and/or the crime of aggression.

Views on cyber aggression. Whether a cyber operation can constitute “use of armed force” within Art. 8 bis(2) is discussed in State positions on the use of force in cyberspace (see charter) and in expert works such as the Tallinn Manual 2.0 (tallinn_manual). No case concerning the crime of aggression committed by cyber means has been brought before the ICC.

Jurisdictional regime. At a special session of the Assembly of States Parties (New York, 7–9 July 2025) reviewing the aggression amendments, States parties adopted a resolution by consensus committing to the aim of strengthening the Court's jurisdiction over the crime of aggression and agreed to reconvene in a further special session in 2029, with an intersessional meeting in 2027.
