Nicaragua v. Germany

Nicaragua v. Germany, formally Alleged Breaches of Certain International Obligations in respect of the Occupied Palestinian Territory (Nicaragua v. Germany), was instituted before the International Court of Justice (ICJ) on 1 March 2024. Nicaragua invoked the Court's jurisdiction principally under Article IX of the 1948 Convention on the Prevention and Punishment of the Crime of Genocide, to which both states are parties, and additionally relied on customary obligations under international humanitarian law and the Geneva Conventions of 1949 with their Additional Protocols. The application followed the Court's January 2024 provisional-measures order in South Africa v. Israel, in which the ICJ found it plausible that acts in Gaza could fall within the scope of the Genocide Convention. Nicaragua positioned its case as a complementary action targeting a third state alleged to be complicit, rather than the principal perpetrator, thereby testing the reach of state responsibility for complicity in genocide.

The procedural mechanics turned on a request for provisional measures filed alongside the application. Under Article 41 of the ICJ Statute, the Court may indicate interim measures to preserve the respective rights of either party pending final judgment, provided it has prima facie jurisdiction, the rights asserted are at least plausible, and there is a real and imminent risk of irreparable prejudice. Nicaragua asked the Court to order Germany to suspend its export of arms and other military equipment to Israel and to reverse decisions denying funding to the United Nations Relief and Works Agency for Palestine Refugees (UNRWA). Public hearings were held on 8 and 9 April 2024 at the Peace Palace in The Hague, with Germany contesting both jurisdiction and the factual premise that its conduct amounted to facilitation of genocide.

On 30 April 2024 the Court delivered its order, declining to indicate the provisional measures Nicaragua sought and refusing Germany's request to remove the case from the General List. The Court reasoned that the circumstances were not such as to require the exercise of its power under Article 41, noting in particular that Germany had stated that the great majority of its 2023 export licences to Israel concerned equipment other than war weapons, and that licences for war weapons had declined sharply in 2024. Crucially, the Court emphasised that the rejection of a provisional-measures request did not prejudge questions of jurisdiction, admissibility, or the merits, leaving Nicaragua free to pursue the substantive claim. The order signalled a high evidentiary threshold for establishing the plausibility of complicity through arms transfers.

The case unfolded against a dense field of contemporaneous Gaza-related litigation. South Africa v. Israel generated successive provisional-measures orders in January, March, and May 2024, the last directing Israel to halt its Rafah offensive insofar as it might inflict conditions of life calculated to destroy the Palestinian group. The ICJ also issued its Advisory Opinion of 19 July 2024 on the Legal Consequences arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, finding Israel's continued presence unlawful. Within Germany, the case intersected with parallel domestic proceedings, including challenges before the Berlin Administrative Court concerning specific export licences, and the Foreign Office in Berlin defended its export-control regime under the War Weapons Control Act and the Foreign Trade and Payments Act.

Nicaragua v. Germany must be distinguished from the better-known Military and Paramilitary Activities in and against Nicaragua (Nicaragua v. United States) of 1986, with which it shares only an applicant state; the 1986 case concerned the use of force and non-intervention. It is also distinct from South Africa v. Israel, which proceeds against the alleged principal perpetrator. The German case is properly understood as a third-state complicity action, raising whether Article III(e) of the Genocide Convention—complicity in genocide—and the obligation to prevent under Article I extend to a supplier of military and financial support. It differs from an inter-state countermeasures dispute and from Arms Trade Treaty enforcement, the latter operating through that treaty's own mechanisms rather than the ICJ.

The proceedings provoked controversy over the justiciability of arms-export decisions, which states traditionally guard as matters of foreign and security policy. Critics argued that imposing ICJ-mandated suspensions could convert the Genocide Convention into a general instrument of arms-trade regulation; supporters contended that Article I's duty to prevent genocide necessarily constrains material support to a state credibly accused before the Court. The April 2024 order left these tensions unresolved, and the case remained pending on the merits, where the Court would confront the demanding standard set in the 2007 Bosnia v. Serbia judgment, which required that complicity be proven with awareness of the specific intent (dolus specialis) of the principal perpetrator.

For the practitioner, Nicaragua v. Germany is a reference point for the legal exposure attaching to arms exports during an armed conflict subject to genocide allegations. Export-licensing officials, legal advisers in foreign and defence ministries, and compliance officers must now weigh ICJ jurisprudence alongside national export-control statutes and the Arms Trade Treaty's prohibition on transfers with knowledge of use in genocide or crimes against humanity. The case demonstrates that a third state may be hauled before the World Court on the basis of its support relationships, and that the plausibility threshold, while high, is not insurmountable. It thereby shapes risk assessments in capitals from Berlin to Washington whenever transfers flow to a party under international scrutiny.
