Workshop Announcement

Max Planck Trialogues on the Law of Peace and War vol. II - The Applicability of International Humanitarian Law, 30-31 March 2017

The applicability of international humanitarian law (IHL) has been a contested issue for decades. However, gen­erally accepted legal solutions have not been found. Recent events, such as the series of terror attacks affect­ing a number of countries or the increasing prominence of hybrid conflicts create further challenges for deter­mining the scope of armed conflict. Against this background, the workshop will espouse a holistic perspective, tackling appli­cability in terms of its scope ratione materiae, personae, and temporis. The workshop will also address new forms of conflict such as hybrid war and deal with the applica­ble legal regimes (IHL & human rights), with their overlap and possible conflicts.


Workshop: Self-defence against Non-state Actors

On 4-5 November 2016 the MPIL hosted the first authors' workshop of the Max Planck Trialogues. The workshop addressed the timely topic of self-defence against non-state actors.

A new Format of Academic Publishing

The book series “Max Planck Trialogues on the Law of Peace and War” will offer a new approach to the law surrounding armed conflict and will make use of an innovative way of academic publishing. Published by Cambridge University Press, it will consist of volumes that are each co-authored by three scholars whose geographical, theoretical, and methodological background and outlook differs greatly. The authors will be asked to write around 80 pages on one and the same issue, approaching it from their own distinct perspective. The idea is to obtain a multi-perspective and discursive yet comprehensive account of a specific problem that highlights the current controversies and the diversity of approaches to that problem.

The individual volumes will pertain to the fields of ius ad bellum, ius in bello and ius post bellum; for example, self-defence against non-state actors, cyberwar, reparations for violations of international humanitarian law (IHL), and the like. The project is (initially) planned as a publication series of nine volumes that will take up classical topics but will also react to recent challenges to the law surrounding armed conflict. 


The Writing Process

In contrast to usual edited volumes, the fact that there are three authors who write on the same topic will guarantee that the subject of one book will be covered both in depth and comprehensively. Moreover, key to the plan is that the three authors will engage in an exchange with each other so that their three voices will have to take into account the others’ perspectives and will thus be mutually enriched. The “trialogue” will happen at authors’ workshops hosted by the Max Planck Institute where authors, further invited commentators and other interested participants will discuss the draft chapters. The additional comments will not be published in the books, but in the Heidelberg Journal of International Law and accompanying blogs. These side publications will further add publicity to the book series. 


Series Editors and Conveners

The book series is edited and coordinated by Anne Peters and Christian Marxsen. The series editors write a short introduction of about 10 pages as well as an epilogue to each book.
