The invasion of Ukraine by the Russian Federation and the subsequent military campaigns entail several classical aspects of armed conflict. First, it is a type of international armed conflict between two sovereign states that had been prevalent until the middle of the twentieth century but not in the last several decades. It is also a direct intervention by a superpower into a neighboring state with the former’s aspiration of territorial expansion. This action evokes a scheme of war reminiscent of the nineteenth or early twentieth century. At the same time, however, the invasion is generating in the international community a sense of new phenomena, leading to a new era that may be different from the past three decades following the end of the Cold War. In fact, the hostilities between the Russian Federation and Ukraine, as well as reactions by other states and international organizations, have raised legal and political issues that require scholars to reexamine existing frameworks of the international community and individual rules of international law.  The process of applying international law to states is a dynamic one. Rules of international law may and should regulate the behavior of states and provide standards to decide whether a particular act by a state is permissible. At the same time, however, states may change or replace existing rules, and a significant event or series of such events may be a strong motivator to create a new legal framework. In this regard, rules of international law and the conduct of states are in a dialectical relationship. International law can both shape a mode of conduct and be shaped by that conduct—being its creator as well as its creation. The Ukraine conflict is not an exception. We can discuss the conduct of the Russian Federation, Ukraine, other states and international organizations and evaluate their legality and legitimacy from the viewpoint of existing rules. However, we may also reevaluate the current rules of international law through the lens of the Ukraine conflict and discuss possible changes to those rules in the future.   Inspired by the latter aspect of the international legal process, the present book aims to examine the impact of the Ukraine conflict, whether salient or potential, on various rules of international law. Most of the authors are from Japan and other Asian countries that are geographically remote from the site of the conflict. It is often true, however — and particularly in this case — that those keeping an appropriate distance can look at relevant issues in a broader view and from a more objective perspective. To what extent and in what manner may the Ukraine conflict have an impact on the legal framework of the international community and the rules of international law? This book is the first to answer those questions in a comprehensive manner.

International human rights law grants individuals both rights and responsibilities. In this respect international criminal and international humanitarian law are no different. As members of the public international law family they are charged with the regulation, maintenance and protection of human dignity. The right and duty to disobey manifestly illegal orders traverses these three schools of public international law. This book is the first systematic study of the right to conscientious objection under international human rights law. Understanding that rights and duties are not mutually exclusive but complementary, this study analyses the right to conscientious objection and the duties of individuals under international law from various perspectives of public international law.

The purpose of this book is to critically examine the activities of the International Criminal Court (ICC) on the eve of its 20th year of existence, with a focus on its relationship to the Rohingya crisis. This book is unique in that it identifies the potential and contemporary challenges of the ICC while focusing on the relationship between the Rohingya issue and the ICC. The relationship between the Rohingya crisis and the ICC is an issue that is fraught with contemporary challenges and worth dealing with. The relationship between the ICC and non-State Parties and the relationship between the ICC and high government officials are the examples of these challenges. Its novelty is to address the relationship between the Rohingya crisis and the ICC by staying current of information. The human rights situation of the Rohingya is of high international concern. With a case pending at the International Court of Justice (ICJ), not only individual criminal responsibility but also State responsibility may be sought for the most serious human rights violations. The Rohingya crisis itself is of great international concern, and it is expected that the issues will be discussed from the perspective of international human rights law, international humanitarian law, and international criminal law. Therefore, the structure of this book is as follows. First, it explains the history of the Rohingya crisis. Secondly, it touches on the relationship between the Rohingya crisis and the ICC. Thirdly, the book discusses the relationship between the ongoing case of Gambia v. Myanmar at the ICJ and the proceedings of the ICC. Finally, the book concludes with an assessment of the legitimacy, effectiveness, and efficiency of the ICC in recent years.
