Présentation

Le droit international est-il juste ? Comment définir la justice et l'équité ? Comment définir la justice ? Comment évaluer le caractère juste du droit international ? Et selon quels critères ? La justice du droit international doit-elle être évaluée en fonction de ses objectifs, de son contenu, de ses conséquences ou de son processus juridique ? Le droit international doit-il être juste ? Peut-il même l'être ? Quelles leçons peut-on tirer des crises internationales passées et actuelles telles que la guerre en Ukraine, la pandémie de COVID-19, ou l'inégalité face aux conséquences préjudiciables du changement climatique ?

Les intervenants - dans le cadre de six forums et douze agoras - réfléchiront à plusieurs questions d'actualité. Le contentieux international, la responsabilité des Etats, les droits de l'homme, le droit pénal international, l'Anthropocène, les ressources naturelles et les espaces communs, l'allocation des espaces maritimes, le droit des investissements, le droit de la paix et de la sécurité, et le droit international de la santé figurent parmi les thèmes abordés dans les agoras.

La conférence sera précédée les 30 août après-midi et 31 août matin de 19 ateliers organisés par les groupes de réflexion de l'ESIL.

The conference will be hybrid.

14.30 : Opening discussion – The Long Quest for Fairness

(Room Portalis)

What does fairness mean ? What are the relationships between fairness, justice (commutative/distributive), equality, equity or proportionality ? Which kind of justice or fairness are we talking about ? Has fairness the same meaning in Europe, in North and South America, in Africa, in Asia ? Is there a single or shared vision, or multiple, variable and possibly contradictory approaches regarding the fairness of international law ? How has it been understood historically ? How far the emergence of feminist approaches or the Third World Approaches on International Law (TWAIL) has renewed the theoretical reflection on equity and justice in international law ?

15.30 : Coffee break

16.00 : Forum 1 - Law as a Way to Fairness or Fairness as a Way to Escape the Law ?

(Room Mistral)

For lawyers, the questions of the relations between law and justice or between law and fairness are among the most classic (and unanswered) ones. Do they come in a distinctive manner in the field of international law ? Is international law used by States and international organizations as a means to achieve fair relations between actors ? What part does fairness take in international law-making ? Does the application of international law by courts necessarily lead to fair results ? Or is fairness a means to mitigate some unfair effects of the application of law and how ? This Forum will be an opportunity to highlight the complex linkages between international law's techniques and methods and the ideal of fairness.

16.00 : Forum 2 - Fairness in the Practice of International Law and Organisations

(Room Dumas)

Fairness has surely been for centuries an aspiration for academics, and it has in some ways penetrated the content of positive law and the purposes of international organizations. But, apart from those theoretical and very programmatic ambitions, to what extent is fairness taken into account by international law practitioners in their day-to-day activities ? What does fairness represent for a State's representative during a negotiation, for a lawyer pleading a case or for the staff members of international institutions ? This Forum will give a pragmatic view of the role of fairness in the very practice of international law.

17.35 : Agora 1 - Fairness in the Process of International Criminal Law

(Room Dumas)

While a fair trial is generally considered a core component of criminal law, the international dimensions of this concept invite several questions. Many criticisms have been raised about the fairness of international trials, frequently denounced as a mere expression of victor's justice. Today, questions remain open as to the rules of the International Criminal Court and other international/hybrid criminal courts : do international criminal tribunals ensure a fair trial for defendants ? What is the role of UN investigative mechanisms ?

17.35 : Agora 2 - International Law in the Anthropocene Era : Where is Fairness ?

(Room Mistral)

As soon as environmental threats become global, international law is called upon to protect the environment. However, the impressive developments in environmental law are not always accompanied by corresponding improvements in environmental quality. It is time to deeply rethink our law, and far beyond international environmental law. This agora will specifically address the issue of fairness between generations in the Anthropocene era.

17.35 : Agora 3 - The Push and Pull of Fairness : Theoretical Approaches to Fairness in International Law

(ESIL Interest Group on International Legal Theory and Philosophy)

(Room Mirabeau)

If we all aspire to fairness in international law and hope to re-imagine it for the 21st century, what are the criteria and parameters for determining fairness ? Agora 3 aims to explore different theoretical approaches to fairness in international law to create space for re-imagining fairness fitting for the 21st century, addressing the following key questions : what is fairness; whether international law can be fair; and what criteria should be used to determine the fairness of international law.

9.00 : Agora 4 - Fairness and Human Rights Law

(Room Mistral)

Is the assumption that human rights are inherently a way to achieve greater fairness warranted ? Does this assumption leave any room for doubt ? Can some human rights norms work against the interests of their alleged beneficiaries ? Can fair human rights rules be misused to serve unfair purposes ? Do human rights charge States with unfair obligations towards individuals, other states, or international organizations ?

9.00 : Agora 5 - Fairness, Natural Resources, Shared Resources, and Common Spaces

(Room Mirabeau)

From the high seas to international watercourses, not to mention migratory species or genetic resources, is there a place and role for fairness in international law when applicable to natural resources, shared resources, and common spaces ? What are the meanings and implications of the principle of equitable utilization of shared resources ? How does one balance equitable catch limitation, share allocation and conservation measures ?

(Room Dumas)

Is international litigation fair ? How do international tribunals award compensation and is their approach fair ? How has the (long) quest for fairness affected the procedural rules of international litigation ? Beyond the fair trial principle, what place is there for fairness and a rule of law-based procedure ? How are international tribunals and parties balancing efficiency and fairness ?

10.30 : Coffee break (Reception hall, Pouillon building)

11.00 : Forum 3 - Fairness and New Subjects of International Law

(Room Mistral)

Does the evolution of international law reflect the evolution of the international society ? Originally, only States qualified as subjects of international law. However, after the Second World War, more and more new actors emerged on the international scene (IOs, NGOs, multinational companies, indigenous peoples, individuals…) and have more or less acquired the capacity to become international legal persons. But international law remains profoundly and inherently state-centric, not to mention humankind, the international community, future generations, the Earth, animals, and, in short, all 'quasi-persons' (in the sense of entities to which part of the doctrine tends to attach a form of legal personality).

11.00 : Forum 4 - Current Events : The Implementation of the Paris Agreement : Where is Fairness ?

(Room Dumas)

The bottom-up approach of the Paris Agreement, based on its Parties' national contributions, nurtures in-depth discussions. States, non-governmental organizations, academics and more broadly civil society, contribute to the debate and carry out assessments of both the ambition and fairness of national contributions on climate change mitigation and finance. The 6th IPCC report itself acknowledges “challenges in assessing fair shares”. Several studies have concluded that developed countries and major emitters' pledges are far from fair while developing countries' contribution generally corresponds to their “fair share” or even exceeds it. Domestic climate litigation brings some answers on the concept of “fair share” and the content and scope of an obligation to “do one's part”, but does not put an end to the discussions, which are becoming ever more acute.Therefore, speakers will be invited to explore some of the following questions : what is a country's “fair share” of effort to combat climate change ? What are the scientific inputs on key concepts such as a global carbon budget or a fair distribution of efforts to reduce GHG emissions or finance decarbonization in the Global South ? What lessons can be learned from domestic climate litigation ? And what can be expected from the upcoming advisory opinions of the International Tribunal for the Law of the Sea, the Inter-American Court of Human Rights or the International Court of Justice ?

14.00 : Agora 7 - Fairness in the Allocation of Maritime Spaces

(Room Mirabeau)

Whether it takes the form of the principle of equidistance or by reference to the search for an “equitable solution”, equity is at the heart of issues of maritime delimitation. The contribution of the international judge has been essential in clarifying its contours and content. How has this jurisprudence been built up over time, and in which international court or tribunal ? What are the options retained by the latter ? The foundations and contemporary developments of this case law deserve to be questioned. Is equity called for by the law beyond the sharing of maritime spaces between States ? Can equity between States be reached as an attenuator of North-South inequalities ?

14.00 : Agora 8 - Fairness and the Law of International Responsibility

(Room Mistral)

Responsibility is classically coined as the necessary corollary of law. But how is responsibility related to fairness and, more specifically, does the international regime of responsibility respond to fairness standards ? The question relates to the conditions of responsibility as well as to its consequences or means of implementation.

François Delerue, Assistant Professor, IE University Law School, Madrid - Spain

14.00 : Agora 9 - The Law of Investments : Is this still Fairness ?

(Room Dumas)

The standard of “fair and equitable treatment”, as part of the protection due to foreign direct investment by host countries, has been interpreted in various ways by governmental officials, arbitrators, and scholars. A growing number of arbitral awards examine claims for denial of fair and equitable treatment and gradually shed light on the normative content of the standard. Is the meaning of the “fair and equitable treatment” standard necessarily the same in all the treaties in which it appears ? Beyond that, is “fair and equitable treatment” really fair ?

17.15 : Agora 10 - Conceptualizing Fairness and International Criminal Justice

(ESIL Interest Group on International Criminal Justice)

(Room Dumas)

What compromises are considered legitimate in light of the egregiousness of the alleged crimes ? How fair is it to impose criminal responsibility on individuals for crimes that are often collective enterprises where perpetrators act together and in concert with thousands of other people ? How can international criminal justice stakeholders build on critiques to devise a more compelling and fair vision of global accountability going forward? Is fairness (or sheer opportunism) at play when narrowing down prosecution on certain individuals or facts ? And how fair is international criminal justice to victims ?

(Room Mistral)

According to the Preamble of the UN Charter, when establishing the UN, the “peoples of the United Nations” were notably “determined […] to establish conditions under which justice and respect for [international law] can be maintained”. Do peace and justice institutions have to be fair ? And how do institutions, like the UN Security Council, that are at the forefront of maintaining peace and security, balance competing values such as efficiency and fairness ?

(Room Mirabeau)

While it is generally acknowledged that International Health Law can be a powerful tool for fairness, gaps in scope and enforceability of existing International Health Law instruments, as well as unregulated areas of major international health concerns, also lead to unfairness, as clearly shown by the pandemic. Building on existing and future challenges, this agora will provide perspectives on the fairness of International Health Law.

(Room Dumas)

Beyond general considerations on the expected fairness of law, this Forum will highlight the peculiarities of the sources of international law. Wondering if international law is fair leads rapidly to a reflection on the fairness of the sources of international law. What place for fairness in international law sources ? Is their typology fair ? Is soft law a means to fairness ?

9.00 : Forum 6 - Unfairness and the Critique of International Law

(Room Mistral)

Critical Legal Studies emerges within international law with the arrival of new states in the 1960s that illuminated international law as a servant of politics and, into the 1970s, through a denouncement of formalist and state-centred approaches. Contemporary critical legal approaches draw on wider understandings of the relationship between law and politics, the indeterminacy of law, and the relationship between law and culture/ society to question the repetition of legal forms in the maintenance of the status quo. This forum will examine how concepts of fairness are understood within and across Critical Legal Approaches to international law.
