Project Description

The Project

The SHARES Project examines an unexplored and largely unrecognised problem: the allocation of international responsibility among multiple states and other actors. It uncovers the nature and extent of the problem of sharing responsibility in an increasingly interdependent and heterogeneous international legal order. The Project produces output, offering new concepts, principles and perspectives for understanding how the international legal order may deal with shared responsibility. The SHARES Conceptual Framework Paper can be found here. See here for an introduction to shared responsibility by Professor André Nollkaemper.

The Context

International society and the international legal order have gone through radical transformations in recent decades, notably in the multiplicity of actors operating in interaction with each other. In a substantial and increasing number of cases, injurious consequences do not result from individual acts by individual actors, but arise from concerted action by states, international organizations and other actors. This occurs for instance in the context of multinational military operations, extra-territorial migration policies, or acts that contribute to climate change and other transboundary environmental problems. The significance of this phenomenon is illustrated in the News section of the SHARES website, where news items relevant to shared responsibility are frequently posted. In all these situations, responsibility may be shared between two or more states and/or other actors.

While concerted action may further the delivery of international common goods, it may come with a downside, as it complicates the allocation of responsibility. Where common action fails to deliver its promises, and in particular when acts and omissions breach rights or obligations, the question of who is responsible will arise. Who, among the multiplicity of actors involved in cooperation, is to answer for the failure to live up to promises and abide by agreements, and who is to provide reparation to any injured parties? The international legal order increasingly has to come to grasps with a truth learned long ago in organization theory: as the responsibility for any given instance of conduct is scattered among more actors, the discrete responsibility of every individual actor diminishes proportionately.

The principles applicable to situations of shared responsibility are not well developed. The International Law Commission (ILC), both in its work on the responsibility of states and the responsibility of international organizations, recognised that attribution of acts to one state or organization does not exclude the possible attribution of the same act to another state or organization. However, the ILC has provided limited guidance to the allocation of responsibility or reparation in such cases. Indeed, the whole issue is undertheorised and underexplored.

The Objectives

As the variety and frequency of cooperative endeavors between states and other actors expand, international rules and processes must be developed to better allocate international responsibility between multiple actors. For this to be achieved, our fundamental understanding of the principles and processes at stake needs to be enhanced. The objective of the SHARES Project is therefore to increase the body of scientific knowledge on the topic, by developing a comprehensive study of theoretical and practical issues of shared responsibility. The project will propose not only a technical and procedural analysis of how to deal with shared responsibility, but will situate such an analysis in a novel rethinking of the nature of international responsibility.

The Output

Over the course of the project, the project team has provided regular output, engaging in academic debates on the topic of shared responsibility, while also aiming at addressing a larger public. This output consists of events (conferences, seminars, lectures, debates) and publications (articles, books, research papers, conference reports and blogposts).

SHARES Events

Conferences
In November 2011, a Conference on the Foundations of Shared Responsibility in International Law was held. It explored fundamental and conceptual issues that explain the state of law, as well as possibilities for further development of the law pertaining to shared responsibility. This conference was also a first take on the findings of the project, and allowed for confrontation with competing and/or complementary approaches.

In October 2015, a workshop was convened to discuss the planning and process for the SHARES Commentaries on the Law of International Responsibility. The Commentaries are a normative authoritative product that can be referred to by judges, practitioners and scholars in conjunction with the ILC Articles. They will be drafted in consultation with experts during 2016, and will be presented in the fall of that year.

Seminars
In order to provide a better understanding of specific areas where issues of shared responsibility arise, a series of expert meetings with professionals and academics was organized at the beginning of the project. Reports of these seminars are available in the areas of international environmental law, refugee law and peace operations. Furthermore, other seminars, in particular related to the SHARES Book Series, have been organized in 2013/2014.

Lectures
Renowned scholars have been invited to give presentations on relevant subjects, dealing with issues of shared responsibility. More information can be found here.

Debates
SHARES Debates have been organised in collaboration with SPUI25, the academic and cultural centre of the University of Amsterdam. These debates are organised throughout the academic year to provide a platform for discussions with a broader (non-academic) audience on questions of shared responsibility.

SHARES Publications

Research Papers
The findings of the project are made available in a Research Paper Series addressing a wide range of general or specific issues of shared responsibility. SHARES Research Papers are available here.

Articles
Key results of the project have been published in articles in leading international journals, including the European Journal of International Law, the Leiden Journal of International Law and the International Organizations Law Review. In addition, articles have been published in edited volumes that are not as such part of the project, but that substantively relate to the SHARES Project. Articles can be found here.
