The International Court of Justice will hear oral arguments on jurisdiction and admissibility in Alleged Breaches of Certain International Obligations in respect of the Occupied Palestinian Territory (Nicaragua v. Germany) from 7 to 10 September 2026. The hearings raise a single, consequential question for practitioners: does Germany's temporal reservation to the Court's compulsory jurisdiction bar Nicaragua's claims, or do Germany's post-2008 arms transfers constitute autonomous disputes falling squarely within the Court's remit?

Germany accepted the ICJ's compulsory jurisdiction on 30 April 2008, but its declaration extends only to disputes arising from "situations or facts" occurring after that date. The rule of temporal limitation, established in the Phosphates in Morocco case (Italy v. France, para. 31), means violations attributable to Germany before 30 April 2008 fall, in principle, outside the Court's jurisdiction under the declaration.

Germany's written pleadings (pp. 39–50) argue that Nicaragua's claims cannot be separated from pre-2008 facts: the Palestinian people's right to self-determination, Israel's occupation of Palestinian territory since 1967, racial discrimination, segregation and apartheid predating 2008, and Germany's longstanding military relationship with Israel. Post-2008 German conduct, Germany contends, cannot be treated as a series of new and autonomous disputes where that conduct forms part of an existing situation whose legal significance derives from facts predating its acceptance of jurisdiction.

The 'Schlussstrich' Problem

Dr. Nahed Samour, Associate Researcher at Radboud University, characterizes Germany's position as an argument for a Schlussstrich—a drawing of a line under the past. The term carries weight in German historical debate, recurring in the Historikerstreit over responsibility for the Holocaust and its successor, Historikerstreit 2.0, concerning Germany's colonial crimes and legal-political support for Israel. The tension is between demands for accountability, prosecution, restitution and reparations for gross violations of international law, and arguments that Germany should reconcile and move on.

Legally, the temporal analysis must account for developments after 2008 that constitute new acts, materially alter the situation, or carry independent legal significance within the Court's jurisdiction. The duty to prevent genocide is central here. The ICJ held in Bosnia v. Serbia (2007, para. 431) that a "State's obligation to prevent, and the corresponding duty to act, arise at the instant that the State learns of, or should normally have learned of, the existence of a serious risk that genocide will be committed."

The Chronology Nicaragua Relies On

Nicaragua argues that each German act after 30 April 2008 constitutes a post-2008 fact or situation in itself—specifically the authorization and supply of arms and military equipment to Israel, in alleged breach of international humanitarian law and of the Palestinian people's right to self-determination.

The timeline is dense. Chancellor Scholz told the Bundestag on 11 and 12 October 2023 that "there [was] only one place for Germany: the place at the side of Israel." Foreign Minister Baerbock stated Germany "offered Israel all [its] support in every area." In November 2023, Germany publicly opposed a ceasefire.

Warnings were mounting. UN Secretary-General statements on 9 October 2023, the ICRC President on 11 October, and an EU High Representative statement on 10 October—with Germany participating in its adoption—flagged grave violations of international humanitarian law. On 27 October 2023, the UN Committee on the Elimination of Racial Discrimination invoked its Early Warning and Urgent Action procedure, citing Israeli Defense Minister Yoav Gallant's description of Palestinians as "human animals" as language that could incite genocidal actions. On 13 November 2023, 15 UN Special Rapporteurs and 21 members of UN Working Groups "pointed to a genocide in the making."

Against this background, the ICJ's Order of 26 January 2024 in South Africa v. Israel found plausible the existence of rights under the Genocide Convention and recognized a real and imminent risk of irreparable prejudice. The Court stated that the prohibition of genocide is an obligation erga omnes (para. 31), and issued further provisional measures in March and May 2024.

The Arms-Licensing Spike

Empirical material submitted to the ICJ (para. 27), drawn from German parliamentary requests (Kleine Anfrage), shows a sharp post-7 October acceleration in export licensing. Germany authorized €326.5 million in military-equipment export licences in 2023—roughly ten times the 2022 figure—with 88% issued in the second half of 2023 and 60% between 7 October and 2 November alone. The largest monthly spike came in October, at roughly €203 million. Approximately 75% of the year's total was authorized between October and December 2023 (paras. 25–30).

On Samour's reading, these figures portray October–December 2023 not as a continuation of pre-existing military support but as a decisive escalation precisely as the violence in Gaza intensified—making temporal limitations difficult to treat as a procedural boundary rather than a shield against scrutiny of Germany's conduct when risks were most acute.

In its Order of 30 April 2024 (para. 24), the ICJ stated: "Court considers it particularly important to remind all States of their international obligations relating to the transfer of arms to parties to an armed conflict, in order to avoid the risk that such arms might be used to violate the above-mentioned Conventions. All these obligations are incumbent upon Germany as a State party to the said Conventions in its supply of arms to Israel."

The Practical Stakes

For practitioners, the jurisdictional phase will turn on whether the Court treats Germany's post-October 2023 conduct as autonomous facts or as a mere continuation of a pre-2008 situation. Samour argues Germany cannot place such conduct outside the declaration's temporal scope by invoking the historical origins of the situation, nor shield its post-2008 conduct behind claims of "substantive financial support to the Palestinians" (para. 32), a domestic "robust and rigorous legal régime" (paras. 11–15), or "assurances" (para. 19) concerning Israel's respect for international humanitarian law.

At no point since October 2023, the analysis notes, has Germany suspended or ceased weapons deliveries to Israel. Where alleged violations concern not simply continuing but subsequently intensified conduct risking breach of ius cogens—including the duty to prevent genocide—the relevant dispute concerns facts arising after October 2023 that could not have formed part of any dispute concerning the situation as it stood before 30 April 2008.

The article also observes that under the Rome Statute of the International Criminal Court, responsible ministers may face individual criminal responsibility for soliciting, aiding and abetting genocide (Articles 6 and 25).

However the Court rules on jurisdiction, the September 2026 hearings will test whether temporal limitation doctrine can cabin a dispute whose operative conduct—arms licensing, delivery and political support—occurred squarely within the Court's jurisdictional window, amid objectively discernible warnings of genocide.
