Summary

In this inaugural lecture for the 2026 academic year at Sciences Po Law School, Judge Nicolas Guillou of the International Criminal Court addresses the provocative question: ‘Does an international rule of law exist?’ He begins by acknowledging the widespread narrative of the collapse of international law, then argues that the situation is more complex. He outlines three possible worlds without an international rule of law: domination by force, wealth, or ideology. The lecture then traces the historical development of this concept, from Kant to the post-1945 order, while highlighting its incompleteness and imperfections. He critiques the colonial origins of international law, the inequality among states (e.g., the veto power), and the problem of double standards in international justice. He also examines legal deficiencies such as legal uncertainty arising from vague norms, the hardening of soft law, the democratic deficit of international judges, and the fragmentation of international law. Despite these challenges, Guillou advocates for a pragmatic and utopian vision of the international rule of law as an evolving process, urging students to contribute to its construction. He emphasizes the importance of international criminal justice and the role of civil society. The lecture closes with a message of hope, inviting future legal professionals to see the project as both necessary and achievable.

Critical Evaluation

Value of the Information & Strength of the Argument

The lecture offers substantial value through its combination of theoretical rigor and practical experience. Guillou does not simply enumerate criticisms of international law; he deconstructs them and provides nuanced responses. For instance, he acknowledges the critique of double standards in international criminal justice but contextualizes it by noting the historical evolution from ad hoc tribunals to the permanent ICC. He also addresses the legal-positivist concerns about norm vagueness and judicial law-making, illustrating with Article 68 of the Rome Statute. The argumentation is coherent: he moves from a definitional framework to a historical assessment, then to contemporary critiques, and finally to a constructive outlook. The speaker openly discusses weaknesses of the system, such as the colonial legacy and the democratic legitimacy gap, which strengthens his credibility. His use of examples—like the ICC’s mandate for Netanyahu and the US sanctions against him—grounds abstract concepts in real-world events. The lecture is not simply an apology for international law; it is a critical yet hopeful evaluation.

Scientific Rigor, Source Quality, Title Accuracy

The lecture demonstrates high scholarly rigor. Guillou refers to key legal instruments and institutions: the UN Charter, the Rome Statute, the European Court of Human Rights, and the International Court of Justice. He also references philosophical traditions (Kant, Abbé de Saint-Pierre) and contemporary legal doctrines (originalism). The presentation structure (first part: project incomplete, second part: contestation, third part: hope) is clear and logical. The title is perfectly matched with the content—the entire lecture is an interrogation of the existence of an international rule of law. Moreover, the speaker’s own experience as a judge facing political pressure (US sanctions) adds authentic weight. The video includes no external source citations in the description beyond official Sciences Po links, but the oral lecture implicitly draws on a deep body of legal scholarship and case law. The absence of visual aids or written references does not diminish the intellectual quality, as the speaker’s authority and reasoning are self-contained.
