This article aims to offer a definition of the international rule of law. It does this through clarifying the core objectives of a rule of law and examining whether the international system could include them. It demonstrates that there can be a definition of the international rule of law that can be applied to the international system. This definition of the international rule of law is not dependent on a simplistic application of a national rule of law, as it takes into account the significant differences between national and international legal systems. It seeks to show that the international rule of law is relative, rather than absolute, in its application, is not tied to the operation of the substance of international law itself, and it can apply to states, international organizations and non-state actors. It goes further to show that the international rule of law does exist and can be applied internationally, even if it is not yet fully actualized.

The chief aim of this article is to unearth, explicate, and contextualize the various techniques on which Mahmut Esat, Turkey's agent before the Permanent Court of International Justice in the Lotus case, drew in order to narrate a fresh understanding of Turkish ‘nationhood’ during a period of intense vulnerability for the newly established Republic. The argument advanced by Turkey in this case – that it need not demonstrate the existence of a specific jurisdictional exception in international law in order to proceed with its prosecution of the French captain of the Lotus, a French vessel – has often been dismissed as an example of cynical apologetics. Nevertheless, a close reading of Turkey's pleadings reveals that it was inclined to oscillate between a variety of universalistic and particularistic approaches, Esat litigating the Lotus with an eye to exploiting the schism that lies at the heart of the concept of ‘civilization’ so as to submit Turkey to the normative authority of the international legal system while bolstering its positive power as an independent sovereign state. More specifically, it was by merging two modes of reasoning – the one prizing systematicity, the other prioritizing sovereignty – that Esat sought to construct a new, robustly reconciliatory identity for the ‘Turkish nation’, one that would enable it to embrace its commitment to international order by securing its place in ‘la civilisation contemporaine’ while amplifying the ambit of its autonomy as ‘un état civilisé’.

The dominant international legal theories are based on an understanding of international law in terms of a solely state-based system. This article challenges those theories in the context of the practice of the participants in the international legal system. It proposes an inclusive conceptual approach which acknowledges that non-state actors have distinct and independent international rights, responsibilities, and abilities to bring claims, as well as clear roles in the creation, development, and enforcement of international law, which are separate to that of states. While states currently have a primary role in the international legal system, this role is not exclusive.
