Biography

After receiving his JD in 2000, Professor Robert D. Sloane worked for the International Committee of Lawyers for Tibet (now known as Tibet Justice Center) under the auspices of Yale Law School’s Robert L. Bernstein Fellowship in International Human Rights. He led fact-finding missions to Nepal, India, and Tibet; wrote submissions for the UN Commission on Human Rights and human rights treaty bodies; represented asylum seekers; and published several reports and law journal articles on human rights. Professor Sloane then served two clerkships, first for Judge Robert D. Sack of the United States Court of Appeals for the Second Circuit and then for Judge Gerard E. Lynch of the United States Court of Appeals for the Second Circuit (formerly of the United States District Court for the Southern District of New York). He also practiced international law at Debevoise & Plimpton in New York, where he focused on international arbitration and litigation and worked on, among other cases, the Avena litigation before the International Court of Justice, challenging the convictions of Mexican nationals on death row based on violations of the Vienna Convention on Consular Relations.

Professor Sloane continues to practice international law periodically as a consultant and has worked on arbitrations conducted under the auspices of the International Tribunal for the Law of the Sea, the International Centre for Settlement of Investment Disputes, the International Chamber of Commerce and specialized tribunals, as well as assisting with the preparation of expert opinions for foreign sovereigns and multinational corporations. He also practices international human rights law on a pro bono basis, chiefly in his capacity as a member of the Board of Tibet Justice Center, a non-governmental organization that seeks to promote self-determination and human rights for the Tibetan people through legal advocacy.

Before joining Boston University School of Law, Professor Sloane served as a visiting lecturer-in-law and Orville H. Schell, Jr. Fellow at Yale Law School, where he taught international human rights and international arbitration, and as an associate-in-law at Columbia Law School.

Professor Sloane’s scholarship focuses on international law and related fields including national security and foreign relations law, the law of war, international criminal law, jurisprudence, and international dispute resolution.

His 2009 article “The Cost of Conflation: Preserving the Dualism of Jus ad Bellum and Jus in Bello in the Contemporary Law of War,” published in Volume 34 of the Yale Journal of International Law, received the Lieber Prize, awarded by the American Society of International Law’s Francis Lieber Society for outstanding scholarship in the field of the law of armed conflict by an author under the age of 35. His 2007 article “Prologue to a Voluntarist War Convention,” published in Volume 106 of the Michigan Law Review, received a certificate of merit from the Francis Lieber Society based on the same criteria. In 2013, he was awarded the Francis Deák Prize for “On the Use and Abuse of Necessity in the Law of State Responsibility,” published in Volume 106 of the American Journal of International Law, awarded by the American Society of International Law for meritorious scholarship in the journal by a younger author. Professor Sloane’s current work focuses on foreign relations law, the uses of ideology in international law, the law of war, and international criminal law.

In 2007, Professor Sloane received a high-level diploma in public international law from the Hague Academy of International Law.

Professor Sloane has been a visiting professor at the University of Michigan Law School (Spring 2010); Harvard Law School (Spring 2011), where he served as the John Harvey Gregory Lecturer in World Organization; the Fletcher School of Law and Diplomacy of Tufts University (2012); Yale Law School (Spring 2014); and the Xiamen Academy of International Law (2016).

Professor Sloane is an elected member of the American Law Institute and serves on the Members Consultative Group for the Restatement (Fourth) of Foreign Relations Law. In 2013, Boston University named him the R. Gordon Butler Scholar in International Law.

Foreign Relations Law

3 credits

This course will introduce the framework of constitutional, statutory, and international law that both authorizes and constrains the conduct of U.S. foreign affairs. After studying the constitutional allocation of foreign affairs powers among the branches of the federal government and basic foundations of the government's national security powers, we will turn to discrete topics of contemporary relevance, which may include most or all of the following: the power and limits of judicial authority in foreign affairs; treaties and other international agreements; customary international law's status in the U.S. legal system; foreign affairs powers retained by the several states; the application of the Constitution to persons and incidents abroad; war powers; covert action; the detention, interrogation, and trial of terrorists and other irregular combatants, before courts and military commissions; targeted killing; torture and other coercive interrogation; and the protection of individual liberties and civil rights in wartime. Current events will be woven into the curriculum as relevant. Grading will be based on a 3-hour final exam. RESTRICTION: Students who have previously enrolled in National Security Law (JD890) may not register for this course.

International Law

4 credits

Sloane: This course will offer a survey of contemporary international law. We will consider both the classical law of nations and postwar developments, which have shifted the fulcrum of the international legal system from a relatively exclusive focus on the rights and duties of states inter se (as between themselves) to a broader focus on all of the participants in the contemporary international legal process—not only nation-states. Nation-states remain the chief actor in international law, but since the nineteenth-century, the amount and more frequent resort to law has led to both new substantive norms (doctrinally) and many new institutions and participants that’re also subject to international law, e.g., non-governmental organizations (NGOs), multinational enterprises of all kinds (MNEs), terrorist networks, criminal syndicates, and, above all, individuals, which in turn has led to int’l law’s effort to create and abide by a specific set of human rights. Specific topics may include (1) the history, nature, and sources of international law; (2) the establishment, transformation, and termination of states and other international legal participants; (3) national incorporation of international law, with a focus on core concepts of U.S. foreign relations law; (4) international law’s allocation of jurisdiction to make and apply law, as well as selected immunities conferred by international law; (5) international law’s effort to protect human dignity through fields such as international human rights, the law of war, and international criminal law; (6) control and regulation of the resources of the planet, with a focus on the law of the sea as a prominent example; and (7) the use of force. George: This course will offer a basic survey of contemporary international law. It will teach students about the major issues of public international law and policy that influence current events, with an eye to both legal theory and modern legal practice. Specific topics will include: (i) the history, theory, and nature of international law; (ii) the sources of international law; (iii) the "actors" of international law -- states, international organizations (with emphasis on the U.N. system); (iv) the domestic incorporation of international law, with a focus on key concepts of U.S. foreign relations law; (v) international human rights; (vi) the use of force; and (vii) humanitarian law.

Law & Ethics of War

3 credits

This seminar will critically examine the legal doctrines and ethical principles of the contemporary law of war, including both the law governing recourse to force (jus ad bellum) and the law governing the conduct of hostilities (jus in bello). Topics vary from year to year. But we’ll cover most if not all of the following: the U.N. Charter framework for collective force; the nature and scope of the inherent right to self-defense; challenges to the jus ad bellum framework posed by terrorist networks and other non-state belligerents; humanitarian intervention; the core rules and principles of the law of armed conflict; non-combatant immunity and its converse, the so-called combatant's privilege; military necessity, distinction, and proportionality constraints on hostilities; prohibited weapons; belligerent occupation; the historical role of reciprocity and consequent difficulties posed by asymmetric warfare; artificial intelligence and "autonomous" weapons; and other controversies that characterize warfare in the early twenty-first century. Grading will be based chiefly on a short final paper. LIMITED WRITING OPTION: With the instructor's permission, a limited number of students may satisfy the upper-class writing requirement through their final term papers. ** A student who fails to attend the initial meeting of a seminar, or to obtain permission to be absent from either the instructor or the Registrar, will be administratively dropped from the seminar.
