Nicaragua Urges ICJ to Reject Germany's Objections Over Arms to Israel

MANAGUA, Sept 9 (International) – Nicaragua on Tuesday asked the International Court of Justice (ICJ) to dismiss Germany’s procedural objections to its pending case, arguing that German arms shipments to Israel violate the Genocide Convention and international humanitarian law. In a formal written submission, the Nicaraguan government contended that Germany’s continued supply of weapons to the Israeli Defence Forces directly contributes to the alleged commission of genocide in Gaza, and therefore should be treated as a co‑responsible party in the dispute. Germany, for its part, replied that the court lacks jurisdiction over the elements of the case concerning its arms exports and that the matter falls outside the ICJ’s competence.

Nicaragua’s filing stems from a broader lawsuit it lodged with the ICJ in early 2024, accusing Israel of breaching the 1948 Genocide Convention by carrying out indiscriminate attacks on civilian populations in the Gaza Strip. The Central American nation, which has a population of just over seven million and spans more than 130,000 square kilometres, has positioned itself as a vocal critic of what it describes as “systemic violence” in the Israeli‑Palestinian conflict. By extending its claim to include Germany, Managua seeks to broaden the legal narrative from a bilateral dispute between Israel and a single petitioner to a multilateral accountability framework that implicates major arms exporters.

Germany, a leading European arms producer and a member of the European Union’s coordinated export control regime, has faced mounting scrutiny over its military sales to Israel, especially in the wake of intensified fighting in Gaza. German officials maintain that the exports are consistent with national law and EU guidelines, which require end‑use assurances and compliance with international humanitarian standards. In its response to the Nicaraguan petition, the German government argued that the ICJ’s jurisdiction is limited to disputes between states concerning treaty interpretation, not to the conduct of third‑party states that have not consented to the court’s authority. It further warned that accepting Nicaragua’s argument could set a precedent for the court to adjudicate on the legality of arms transfers worldwide, a step it deems beyond the court’s remit.

Legal scholars note that the ICJ’s jurisdiction is predicated on the consent of the parties involved. While Nicaragua and Israel have both accepted the court’s jurisdiction for the genocide claim, Germany has not. The German position therefore rests on a well‑established procedural principle: a state cannot be bound by a judgment it has not voluntarily submitted to. However, Nicaragua’s strategy is to frame the German exports as an integral component of the alleged genocidal acts, effectively seeking to attach joint and several liability. If the court were to entertain that argument, it could open the door to broader interpretations of state responsibility under the Genocide Convention, potentially affecting other arms‑exporting nations.

The dispute also reflects the increasingly politicised environment surrounding international legal mechanisms. Nicaragua, under President Daniel Ortega, has cultivated alliances with countries that are critical of Western foreign policy, while Germany remains a cornerstone of the EU’s diplomatic and economic architecture. The case illustrates how smaller states can leverage international institutions to amplify geopolitical concerns, even when the underlying legal questions are complex and contested.

The outcome of the ICJ’s deliberations could have ramifications beyond the courtroom. A ruling that acknowledges Germany’s liability would intensify scrutiny of the global arms trade, prompting calls for tighter export controls and greater transparency in defense procurement. For the broader region, especially for countries dependent on imported military equipment, such a precedent could reshape supply‑chain dynamics and influence national security calculations. Moreover, the case underscores the growing intersection of human‑rights law and weapons transfers, a nexus that may shape diplomatic engagements and trade policies in the years ahead.
