In recent years, the increasingly frequent and, in certain contexts, extremely severe impediments to the provision of humanitarian assistance to civilians in need have focused attention on how to enhance compliance with the rules of international humanitarian law (IHL) that regulate humanitarian relief operations. Efforts to hold accountable parties to armed conflict and persons responsible for unlawfully impeding humanitarian relief operations face the challenge that the underlying rules give parties latitude in how to implement the central obligation to allow and facilitate the rapid and unimpeded passage of humanitarian supplies, equipment and personnel. This article outlines the rules of IHL regulating humanitarian relief operations and highlights the difficulties, in the majority of situations, of determining whether they have been violated. It then presents current endeavours to promote accountability. It concludes with some reflections on whether the threat of accountability is the most effective way of enhancing compliance with this area of IHL, at least while efforts are under way to negotiate access.

Applying human rights beyond state borders is thorny. Which law governs the property rights of a Palestinian whose orchard lies across the Israeli border, or the cross-border shooting of a Mexican citizen by a United States border control agent? This article explores the relationship between constitutional law and international law in the extraterritorial enforcement of human rights by offering a typology of models: the American, European and Israeli models. These models are analysed comparatively, highlighting their chosen legal source of rights: the American model applies constitutional law, the European model uses international law, and Israel combines the two.

The article argues that the choice between constitutional and international law is important as it affects the nature and scope of rights, and reflects the relationship between the state and the territory it controls or within which it acts. The dynamic formation process of the Israeli model demonstrates the multiple possible ways to combine these two sources of law and formulate the relationship between them.

All three models share a ‘constitutional mindset’: the use of basic legal concepts and reasoning in legally grey zones. However, these transnational processes are not deterministic and could result in original concepts, contradictions and discrepancies, as well as serve different political visions.

The use of proportionality and balancing by the European Court of Human Rights (ECtHR) is inconsistent and does not provide clear guidelines from which policies can be drafted that could strike a fair balance between individual rights and public interests while not impairing the essence of the rights at stake. While ad hoc and unprincipled balancing may be justified on the theoretical level, on the practical level a policymaker seeking to understand which infringements constitute clear violations of the European Convention on Human Rights (ECHR) is left confused. This article adds clarity to this state of bewilderment by breaking down several aspects of the ECHR rights to a fair trial into clear-cut ‘red lines’, or minimum thresholds of protection. Overstepping those could result in a violation of the right concerned. Identifying these red lines is intended to assist legislators and policymakers in drafting laws and policies that conform with the obligations of their states under the ECHR, and to instruct policymakers outside the member states of the Council of Europe. Because of its unique characteristics, as well as the volume and breadth of its case law, the jurisprudence of the ECtHR can be a lodestone for the consolidation of an international human rights community based on shared values. The unique contribution of this article is the assessment of ECtHR jurisprudence not only on its own merits, but also in comparison with the jurisprudence of other international courts.

Thomas D Grant's Aggression Against Ukraine: Territory, Responsibility and International Law (Palgrave Macmillan 2015) is the first book which offers a careful, meticulous examination of all aspects of Russia's involvement in Crimea in 2014 in terms of international law, as well as of both Russian and Ukrainian municipal legal orders. It covers probably the widest possible spectrum of legal issues connected with Russia's involvement in Crimea and provides a comprehensive, analytical overview of relevant modern rules of international law in the field of territorial integrity, self-determination and use of force.

International investment law is usually oriented to protect investors while cultural heritage law focuses on the protection of unique items and activities of cultural value. These two subsystems coexist and increasingly intersect within the international legal system, mainly in the context of investment arbitration proceedings, where domestic cultural policies are balanced against the interests and rights of foreign investors. The interplay between these subsystems entails legal complexities and challenges and, as a result of the increasing number of cultural heritage disputes, demands new approaches in the fields of cultural governance, international relations and dispute settlement. These issues are thoroughly addressed by Valentina Vadi in her book Cultural Heritage in International Investment Law and Arbitration (Cambridge University Press 2014).
