This article is about the United Nations (UN) and International Law. It is not about internal developments at the UN. It is not about new Committees or other UN structures, relations with Specialized Agencies or indeed other major international organizations. I have not taken a snapshot today, but rather seek to show how the UN has, through the 70 years of its existence, had an impact on international law.

This article takes Pieter Kooijmans’ 1964 book as the launching point for a discussion of contemporary issues relating to the legal equality of States in the context of immunity from suit. It assesses the strengths of the ‘Grundnorm’ of sovereign equality and examines whether it has any real role to play in providing answers to current problems, including whether immunity should be set aside in the face of claims that a foreign State or its agent has committed human rights violations. Close attention is paid to the 2012 Judgment of the International Court of Justice in the Jurisdictional Immunities of the State case. That Judgment demonstrates that sovereign equality has not yet been replaced as the generating principle of law in the realm of immunity. At the same time, there is an emerging alternative approach centered on the individual rather than the State.

This article, based on a lecture offered in honour of Professor Cleveringa, provides some insights into the difficult question of ‘unjust laws’ and the place of ethics in law, with an emphasis on international law. While this question has long been a bone of contention between natural lawyers and positivists, it has a particular importance in international law. Attention is paid to the role of ethics in the context of non-discrimination and armed conflicts.

Thomas M. Franck was born in 1931 in Berlin, Germany. His family left only in 1938, securing entry to Vancouver, Canada. He arrived speaking German, but rapidly acquired proficiency in English and completed his schooling there.

In this speech delivered at the conference honouring Professor Dugard, President Higgins discusses various human rights issues that have come before the International Court of Justice, including self-determination, reservations to human rights treaties, the application of human rights instruments to occupied territories, and allegations of genocide by one state against another. President Higgins notes that in the past few decades the ICJ has been joined by regional human rights courts, commissions and treaty monitoring bodies. Similar human rights claims are surfacing in these diverse fora, but the acknowledged expertise of these specialist bodies and the desire to avoid fragmentation provide an impetus for all concerned to seek common solutions on evolving points of law.

This Keynote speech examines the implications of the multiplying of judicial institutions and the deepening of international law. Overlapping jurisdiction issues already exist among international courts and tribunals. This raises the question of ‘Whose view prevails?’ But the deepening of international law also requires any given court to ask itself, ‘Which of the many norms now developed are applicable?’ Alternative plausible applicable norms could lead to different solutions. It is ever more apparent that that law is more than ‘bright rules’ that simply need to be applied. This speech discusses potential solutions that have been proposed, such as instituting a judicial hierarchy, using certain provisions of the Vienna Convention on the Law of Treaties, and invoking a hierarchy of norms. It closes with a call for international judges to regard the multiplication of institutions and applicable norms as an opportunity rather than a problem, to read each other's judgments, respect each other's work and try to preserve unity unless context dictates otherwise.
