The International Court of Justice (ICJ) faces a critical question in the Nicaragua v. Germany case: whether the Monetary Gold principle renders the dispute inadmissible. Under this rule, the ICJ is prohibited from deciding on a state’s liability if such a judgment would necessitate a ruling, whether directly or incidentally, on the liability of a state that is not participating in the litigation. In this case, the issue centers on whether the Court can assess Germany’s obligations under the 1948 Genocide Convention and the 1949 Geneva Conventions without directly adjudicating Israel’s actions.
The Legal Framework of the Monetary Gold Principle
Dr. Marco Longobardo, a Reader in International Law at the School of Law of the University of Westminster, argues that the principle does not apply here. He emphasizes that the obligations to prevent genocide and ensure International Humanitarian Law (IHL) compliance are triggered by the risk of violations, not their actual occurrence. This distinction is pivotal, as it shifts the focus from Israel’s past conduct to Germany’s preventive duties.
Key Precedents and Legal Interpretations
The ICJ’s 2007 Bosnia v. Serbia ruling determined that the duty of a State to prevent genocide, and the related obligation to act, are triggered the moment the State becomes aware, or should reasonably have become aware, of a “serious risk” that genocide will occur. This standard was endorsed in Belgian case law and mirrored by UK and Dutch courts in IHL contexts. Longobardo notes that these rulings underscore the preventive nature of the obligations, which do not require proof of actual violations.
Germany, however, contends that Nicaragua’s claims hinge on Israel’s alleged breaches of international law. In its preliminary objections, Germany argues that Nicaragua’s application is “replete with assertions” about Israel’s responsibility, which creates a dependency on prior determinations of Israeli culpability. This line of reasoning, Longobardo counters, misinterprets the scope of the Monetary Gold principle.
Nicaragua’s Legal Strategy and Challenges
Nicaragua’s case rests on two central allegations: Germany’s failure to prevent genocide in Gaza and its neglect to ensure respect for IHL. The country asserts that Germany’s obligations are activated by the risk of atrocities, not by Israel’s actual actions. This perspective is consistent with Nicaragua’s position that establishing whether a genocide occurred cannot be a requirement for determining liability for failing to prevent it.
Yet, Germany’s arguments highlight a strategic challenge for Nicaragua. The German delegation points to Nicaragua’s repeated references to Israel’s alleged breaches, suggesting the case may inadvertently implicate a non-party state. Longobardo acknowledges this risk but argues that the ICJ can distinguish between assessing Germany’s conduct and making findings about Israel’s responsibility.
Germany’s Reliance on the Bosnia v. Serbia Precedent
Germany’s primary legal argument hinges on the Bosnia v. Serbia dictum that the duty to prevent genocide is violated only if a genocide occurs. Russia case.
Longobardo supports the latter position, referencing the Corfu Channel case, in which the ICJ found Albania responsible regarding mines laid by Yugoslavia, a state that was not a party to the proceedings.

Recent Developments and Expert Analysis
Recent ICJ orders on provisional measures in the South Africa v. Israel case have provided evidence on genocide. Longobardo notes that the ICJ’s UNRWA advisory opinion mentioned that its findings are not to be understood as prejudging matters of fact or law that will be determined in the South Africa v. Israel case or other contentious cases.
Legal scholars have emphasized that the Monetary Gold principle is an “exceptional” rule, not a default barrier.
FAQ: Answers to Common Questions
What is the Monetary Gold principle?
The Monetary Gold principle prohibits the Court from hearing a case if the core subject is the responsibility of a state not party to the proceedings, or if determining the respondent state’s responsibility requires the ICJ to first establish the responsibility of another state not party to the proceedings.
Why is this case significant for international law?
The case tests the limits of the Monetary Gold principle in the context of preventive obligations.

What role do advisory opinions play in this case?
Nicaragua points out that the Court can consider other authoritative determinations and advisory opinions as ‘givens’ without triggering the Monetary Gold principle.
ICJ findings not a conclusive determination on responsibility
The ICJ’s UNRWA advisory opinion noted that its findings do not amount to a conclusive determination on responsibility in the South Africa v. Israel case.
