Study

This course offers a broad introduction to international law and provides a foundation for more specialized courses.  Topics covered include the key sources, actors, and institutions of international law; the application of international law by domestic courts; adjudication by international tribunals; the extraterritorial application of domestic law.  Part I of the course provides an overview of these foundations issues.  Part II is comprised of a series of case studies on selected topics in international law, including human rights, international crimes, international trade and investment, environmental protection, and the use of force.

Note on scheduling: To accommodate Professor Helfer’s responsibilities as a member of the UN Human Rights Committee, which meets in Geneva, Switzerland in late February and March 2025, several class meetings will need to be rescheduled or held on Zoom. Details will be provided in the course syllabus for Spring 2025.

This course covers the basic rules governing the U.S. income taxation of international business and investment transactions. After a brief explanation of basic American income tax concepts, the principal rules of taxation relating to income of American taxpayers that is earned abroad, and the income of foreign taxpayers that is earned in the U.S., will be described and discussed. The course will then focus on how the United States’ rules interact with taxation systems in other countries, exploring the concepts of source of income and residence of the taxpayer, and their role in the tax rules relating to international trade. The course will also include consideration of the role of bilateral tax treaties as a means of promoting crossborder investments and international trade through the avoidance of international double taxation. The OECD model treaty will be examined as an illustration of the interaction between double tax treaties and domestic regulations. The course will also describe and discuss the role of transfer pricing in tax avoidance efforts by business taxpayers, especially U.S. multinational corporations.  Finally, the course will explore recent developments in the international effort to reduce tax-base erosion and income shifting among taxing jurisdictions.

International trade and the World Trade Organization attract a lot of attention and debate. Why do almost all economists say that liberalizing trade flows is a good thing? Why do politicians – even ones who purportedly support free markets – often rail against import competition and "unfair trade"? How does trade liberalization interact with other public policy choices such as protecting the environment or promoting the economic development of poor countries? In this course, we will examine why the WTO exists, how it developed from the GATT and how it fits in the international economic order (Part I). The course will offer you an in-depth, practical knowledge of substantive WTO law drawing heavily on case law. It will address the basic principles of trade in goods and trade in services, as well as some of the more specialized WTO agreements on, for example on trade remedies (subsidies, anti-dumping and safeguards). From a more procedural side, the course will pay close attention to the unique WTO mechanism for the solution of global trade disputes, with special reference again to recent and ongoing cases (Part II). It will conclude by examining U.S. trade law – particularly the widely-used trade remedies laws – and assessing not only the practice of international trade law in the United States, but also whether these laws actually achieve their supposed policy objectives (Part III). Although this course will necessarily address key principles and theories undergirding the international trade law system, one of its driving themes will be the actual practice of this discipline in the United States and at the WTO. The course will be graded based on class participation and a final exam.

This seminar will examine the international law of armed conflict, and it focuses on the jus in bello context. Students will consider the rationale for the key concepts of the law of armed conflict and examine their practical application in various contexts. Case studies (to include the wars in Ukraine and Israel as well as other contemporary and historical conflicts) will be examined in conjunction with the topics covered. This historical context for the law of armed conflict agreements, the status of conflicts, combatants, and civilians, targeting, rules of engagement, war crimes, are all included among the topics the class will address. In addition, the impact on conflicts of technologies related to artificial intelligence, drones, cyber and space will be examined. Students are encouraged to relate legal and interdisciplinary sources to better understand the multi-faceted interaction between law and war. There is no examination for this course but a 30-page paper (constituting 60% of the grade) is required on a legal topic chosen by the student and approved by the instructor. Students desiring to use the course paper to fulfill Substantial Research and Writing Project (SRWP) and possibly other writing requirements must obtain instructor approval. The remainder of the grade (40%) is based on the quality and frequency of class participation. Students should be aware that this course may include discussion and visual depictions (still and video) of armed conflict and other acts of extreme violence. The textbook for this course is Gary D. Solis's The Law of Armed Conflict: International Humanitarian Law in War (3rd ed., 2021). Students are required to attend part of the 30th Annual National Security Law Conference Friday, 28 February, and Saturday morning, 1 March 2025 at the Law School. This course is only offered in the spring.

This course will offer an extended exploration of the earliest legal materials known to human history (beginning with the Laws of Ur-Namma) and, arguably, the ancient world’s most important legal materials for the history of law in the Western tradition—namely, the Bible. The course thus provides students with wide exposure to the history of law, indeed its very roots (at least for the Western intellectual tradition), while at the same time affording access to the long and complicated interrelationships of law and religion that are evident already in the ancient world and that continue to the present day, not least (for example) in debates over the Ten Commandments. In these ways, the course should prove helpful and informative, not only in terms of legal history and development, but also in moving toward a better understanding of at least some of the dynamics surrounding religious law and/or religious groups’ and individual adherents’ relationship(s) to law.  Students will be evaluated on class participation, including tracking and presenting on a legal topic (e.g., status, property, family, intention, homicide, etc.) across the semester, and either a series of shorter papers or a longer research paper to satisfy the SRWP.
