ICC Palestine Investigation

The ICC Palestine investigation rests on a contested chain of jurisdictional instruments rather than on a Security Council referral. Its legal foundation began on 1 January 2015, when the State of Palestine lodged a declaration under Article 12(3) of the Rome Statute accepting the Court's jurisdiction retroactively from 13 June 2014, and on 2 January 2015 acceded to the Rome Statute itself, depositing its instrument with the UN Secretary-General. The Secretary-General accepted the accession, and Palestine became a State Party on 1 April 2015. This sequence is decisive: the Court derives territorial jurisdiction under Article 12(2)(a) from the locus of the alleged crimes — Gaza, the West Bank and East Jerusalem — and personal jurisdiction over nationals of States Parties under Article 12(2)(b). Israel is not a State Party, having signed but not ratified the Statute and later renouncing its signature obligations in 2002.

Procedurally, the matter advanced through the standard preliminary examination and authorisation track set out in Articles 13(c), 15 and 53. Prosecutor Fatou Bensouda opened a preliminary examination on 16 January 2015. On 20 December 2019 she concluded that the statutory criteria — subject-matter jurisdiction, admissibility and the interests of justice — were satisfied, but, given the novel question of whether Palestine qualified as a "State" able to confer territorial jurisdiction, she requested a ruling from Pre-Trial Chamber I under Article 19(3). On 5 February 2021 the Chamber held, by majority, that the Court's territorial jurisdiction extends to the Occupied Palestinian Territory comprising Gaza, the West Bank and East Jerusalem, expressly stating it was not adjudicating statehood under general international law or settling final borders. Bensouda formally opened the investigation on 3 March 2021.

The investigation's temporal scope runs from 13 June 2014 onward, capturing the 2014 Gaza hostilities (Operation Protective Edge), settlement activity in the West Bank as a potential violation of Article 8(2)(b)(viii) of the Rome Statute, and the conduct of Palestinian armed groups. Because jurisdiction is open-ended, conduct in the Gaza hostilities that began on 7 October 2023 falls within the same situation rather than requiring a fresh referral. The Prosecutor may proceed against nationals of non-States Parties, including Israeli officials, where the alleged crimes occurred on the territory over which a State Party has conferred jurisdiction — the principle that underpinned the same Court's exercise of jurisdiction over US nationals in the Afghanistan situation.

The contemporary centre of gravity shifted on 20 May 2024, when Prosecutor Karim A. A. Khan KC announced applications for arrest warrants against Israeli Prime Minister Benjamin Netanyahu and Defence Minister Yoav Gallant, and against Hamas leaders Yahya Sinwar, Mohammed Deif and Ismail Haniyeh, the last three subsequently withdrawn or rendered moot by their deaths. On 21 November 2024 Pre-Trial Chamber I issued arrest warrants against Netanyahu and Gallant for crimes against humanity and war crimes, including starvation of civilians as a method of warfare under Article 8(2)(b)(xxv). The Chamber rejected Israel's Article 18 and Article 19 jurisdictional challenges, holding that the 5 February 2021 ruling governed and that complementarity had not been satisfied by Israeli domestic proceedings.

The investigation must be distinguished from adjacent fora. It is not the same as the case before the International Court of Justice in South Africa v. Israel, which concerns inter-state obligations under the Genocide Convention and cannot impose individual criminal liability. Nor is it equivalent to a UN Human Rights Council Commission of Inquiry, which produces reports without prosecutorial power. The ICC's distinguishing feature is its capacity to issue binding arrest warrants enforceable by the 125 States Parties under Part 9 of the Rome Statute. It also differs from the doctrine of universal jurisdiction exercised by national courts, since the ICC's reach is delimited by treaty consent and the complementarity principle of Article 17.

Controversy has been acute and multidirectional. The United States imposed sanctions on Prosecutor Bensouda and senior official Phakiso Mochochoko in September 2020 under Executive Order 13928; the Biden administration lifted them in 2021, and in February 2025 Executive Order 14203 reimposed sanctions targeting Prosecutor Khan and ICC personnel. Several European States Parties — including Germany, France and Italy — have signalled ambivalence about arresting Netanyahu despite their Article 27 and Article 98 obligations, exposing tension between treaty duty and political alignment. The Prosecutor's office has itself faced institutional strain following allegations against Khan that prompted his temporary withdrawal from active duties in 2025.

For the working practitioner, the situation is a live laboratory of the Rome Statute's outer limits. It tests whether territorial jurisdiction can attach through the consent of an entity whose statehood remains internationally contested, whether sitting heads of government and defence ministers of non-States Parties enjoy any immunity before the Court given Article 27 and the Court's reasoning in the Al-Bashir Jordan appeal, and how States Parties reconcile cooperation obligations with bilateral diplomacy. Desk officers tracking travel by warrant subjects, legal advisers assessing arrest obligations, and analysts forecasting the durability of the Rome Statute system all return to this file as the defining stress test of international criminal law's reach against powerful non-party states.
