Subjects of International Law


vrouwe justitia 2

Subjects of International Law can be described as those persons or entities who possess international personality. Throughout the 19th century, only States qualified as subjects of international law. After, the Second World War, more and more new actors emerged in the international legal arena such as the intergovernmental organizations created by States, Non-Governmental Organizations (NGOs) created by individuals, multinationals and even natural persons (i.e. individuals). These can now be considered as having to a large or sometimes limited extend the capacity to become international persons.

  • Saganek, P., Unilateral Acts of States in Public International Law, Leiden, Brill Nijhoff, 2016.


    In Unilateral Acts of States in Public International Law Przemysław Saganek discusses one of the most important sources of States’ obligations in international law.
    He analyzes in a critical way the classical catalogue of unilateral acts comprising: promise, waiver, recognition and protest. He convincingly proves that this list is misleading as it oversees several important acts of States. On the other hand, several classical acts do not necessarily give rise to legal effects or are not necessarily unilateral. The author undertakes a thorough analysis of several types of acts, showing their similarities and dissimilarities. He concludes that the group category of ‘unilateral acts’ covers such diverse elements that they could be hardly codified in a single set of rules.

  • Palaco Caballero, F. de M., La Cour Internationale de Justice et la Protection de l'Individu, Genève, Université de Genève, Faculté de Droit, Paris, LGDJ-Lextenso Éditions, 2015.


    La jurisprudence de la Cour internationale de justice en matière de protection de l'individu tend à poser les bases d'une réflexion d'ampleur ayant pris forme après la Seconde guerre mondiale. Ce mouvement né de l'esprit des droits de l'Homme d'après-guerre semble aujourd'hui vouloir irradier l'ensemble du droit international moderne au point de conduire à une refonte de ses règles traditionnelles. S'affranchissant de la conception classique du droit international où l'individu est tributaire de la volonté des États, la Cour, organe judiciaire principal des Nations Unies, va reconnaître de manière progressive l'individu en tant que destinataire effectif de droits internationaux. Toutefois, cette volonté d'ouverture marquée par la consécration d'un corps de normes et principes applicable en toutes circonstances reste tiraillée entre la protection effective des droits fondamentaux de l'individu et le respect de la volonté souveraine des États parties.

  • Noortmann, M., A. Reinisch and C. Ryngaert (eds.), Non-state Actors in International Law, Oxford, USA, Hart Publishing, 2015.


    The role and position of non-state actors in international law is the subject of a long-standing and intensive scholarly debate. This handbook explores the participation of this new category of actors in an international legal system that has historically been dominated by states. It explores the most important issues, actors and theoretical approaches with respect to these new participants in international law. It provides the reader with a comprehensive and state-of-the-art overview of the most important legal and political developments and perspectives. Relevant non-state actors discussed in this volume include, in particular, international governmental organisations, international non-governmental organisations, multinational companies, investors and armed opposition groups. Their legal position is considered in relation to specific issue-areas, such as humanitarian law, human rights, the use of force and international responsibility. The main legal theories on non-state actors’ position in international law – neo-positivism, the policy-oriented approach and transnational law – are covered at the beginning of the publication, and the essential political science perspectives – on non-state actors’ role in international politics and globalisation, as well as their soft power – are presented at the end.

    497 E 25

    Avec cette nouvelle collection consacrée aux Grandes  pages du droit international, l’Institut des hautes études internationales  a choisi d’entreprendre l’étude du passé de la doctrine  internationaliste, pour y partir à la  recherche des pages qui permettraient de comprendre mieux le présent, mieux le  penser et, idéalement, mieux nommer les choses. Il s’est représenté cette  doctrine comme un vaste champ, laissant à chacun de ses membres le soin d’y cueillir des fleurs éparses, selon son propre choix et ses affinités  personnelles. Dans la composition de ce premier petit bouquet  consacré aux sujets du droit international, on ne cherchera d’autre critère que  le goût de l’Institut et celui de ses doctorants, docteurs et professeurs ayant  conçu collectivement la journée d’études dont cet ouvrage est issu. Le lecteur y retrouvera, ou y découvrira, l’étonnante diversité doctrinale qui fait la richesse, et la difficulté, du droit international.

    peoples and international law

    Peoples and International Law is a detailed survey of the law of self-determination with a focus on the concept of nations and peoples. It engages with different aspects of this law with particular emphasis on the drafting and implementation of international instruments. The second edition includes new coverage of the Declaration on the Rights of Indigenous Peoples and the African and Arab charters. It considers recent practice by the Human Rights Committee, Committee on Economic, Social and Cultural Rights and African Commission on Human and Peoples’ Rights dealing with the emerging political, economic and environmental aspects of the right. The book looks at the interaction of international law, nationalism and liberalism in theories of nationhood and self-determination, as well as, the historical development of the right and the decisions of international bodies. Lastly, it examines practice in this area, including new developments in remedial independence and international territorial administration.

  • Kettemann, M.C., The Future of Individuals in International Law: Lessons From International Internet Law, The Hague, Eleven International Publishing, 2013.


    The state-centric international order is in flux and the role of the individual as an actor in international law is growing. Yet in most international law regimes, states continue to interposition themselves between individuals and international law. Against the background of humanization which is shown to permeate all international legal regimes, this book sketches the future of individuals in international law. From the normative success of International Internet Law as the most innovative post-interposition regime this book draws lessons for the optimal design of (existing and emerging) legal frameworks. Describing in detail the characteristics of a post-interposition regime, including a commitment to multistakeholderism, non-traditional normative instruments and system-wide disintermediation, this book demonstrates why the future of individuals in international law looks bright.

  • The Influence of NGOs on International Law

    From a traditional point of view, International Public Law has been understood as a set of rules produced by states in order to regulate relations between them. Since the end of the Cold War, the role of NGOs in international law is growing in importance and their activities are reaching the remotest parts of the world. In this blog, I will briefly discuss how NGOs have transformed international law as well as how they continue to contribute to the development of international law.
