Navigating The Eu’S Corporate Sustainability Due Diligence Directive: Strategic Implications For Us Companies, Silvia Ciacchi, Michael Faure, Sharon Oded

Michigan Business & Entrepreneurial Law Review

The European Union’s (“EU”) Corporate Sustainability Due Diligence Directive (“CSDDD” or the “Directive”) introduces new human rights and environmental obligations that reshape global corporate governance. This paper explores its impact on US companies, with a particular focus on compliance strategies under both direct and indirect applicability. It contrasts tactical compliance, which emphasizes risk mitigation while meeting minimum legal requirements, against strategic compliance, where companies use sustainability to gain a competitive edge in the market.

This paper highlights how varying enforcement levels across EU Member States may incentivize companies to “forum shop” or choose jurisdictions with more relaxed enforcement. It also …

Insurgent Until Proven Innocent: Land, Power, And The Right To Defend Rights, Kelsey Jost-Creegan

Michigan Journal of International Law

As the climate crisis intensifies, advocates worldwide have stood up to defend their communities, territories, and environment. In response, they have faced violent retaliation. This repression persists despite evolving international, regional, and national-level legal frameworks around the “right to defend rights” and the “right to protection.” This article begins by providing a comprehensive overview of this evolving legal landscape. Against this backdrop, the article examines the tactics and architectures of violence used to repress land and environmental defenders through the lens of counterinsurgency theory.

The article proposes a typology of counterinsurgent violence including: surveillance; stigmatization; criminalization; arbitrary detention; infiltration; cooptation; …

The Gender Of International Criminal Law, Caroline L. Davidson

Michigan Journal of International Law

Notwithstanding the recognition of select gender-based crimes as international crimes and the International Criminal Court’s prosecutors’ professed commitment to seeking justice for gender-based crimes, core doctrines of international criminal law (ICL) obstruct accountability for gendered violence. This article identifies the overlooked gendered implications of a few substantive pillars of ICL: a de facto insistence on a connection to war (“war fetish”), a preoccupation with powerful men, and a focus on the “mastermind” of the crime to the exclusion of other culpable perpetrators.

These substantive pillars, some long-standing and some more recently erected, obscure the vast landscape of gender-based crimes and …

Human Rights, Between Peace And Dignity, Ryan Liss

Michigan Journal of International Law

Today, it seems self-evident that human rights are enshrined at the international level because they protect universal human dignity—a cosmopolitan entitlement that cannot be left to the contingencies of domestic law. The prevalence of this received wisdom, however, masks a fundamental transformation in the idea of human rights over the last century. When human rights were first enshrined in international law—during and following the Second World War— their international status was not seen to be justified primarily by the inherent dignity of persons, but by the instrumental role human rights were understood to play in securing interstate peace. This article …

‘Insistent’ Objectors: The (Ab)Use Of Procedural Defenses Before The International Court Of Justice, Damian A. Gonzalez-Salzberg, Eoin Campbell

Michigan Journal of International Law

Procedural defenses refer to tactical devices that object to either a court’s jurisdiction or to the admissibility of an application, aimed at stopping a court from deciding on the merits of a case or, at least, at limiting the scope of its decision. From its creation in June 1945 and up to the end of 2024, the International Court of Justice (“ICJ”) has adjudicated 101 cases, with almost 80% of them featuring procedural defenses raised by states. These defenses have not only been plentiful, but have been extremely effective, leading to the ICJ’s refusal to decide on the merits of …

The International Order, International Law, And The Definition Of Security, Harlan Grant Cohen

Michigan Journal of International Law

As economic security has seemingly moved to the center of American and European foreign policy, both the United States and the European Union have broadened their interpretation of international law rules governing security, coercion, and intervention. But these interpretations are not exactly new, echoing developing state interpretations of international law that developed states had long ago seemingly rejected. How are these once moribund interpretations of security, force, and coercion being brought back to life?

This article argues that these interpretative shifts highlight the role of the international order as an interpretative mechanism within international law. Borrowing from the work of …

The Justice For Victims Of War Crimes Act: A Dangerous Expansion Of Universal Jurisdiction To Non-International Armed Conflicts, Yuyan (Nicole) Zhang

Michigan Journal of International Law

Universal jurisdiction over war crimes committed in noninternational armed conflict (“NIACs”) has yet to develop a firm legal foundation under international law. The Justice for the Victims of War Crimes Act of 2023, however, amended the War Crimes Statute (18 U.S.C. § 2441) and extended universal jurisdiction to NIACs. This overreach risks infringing on the sovereignty of NIAC-affected states and destabilizing their ongoing peace processes. Many such states prioritize reconciliation through mechanisms like truth commissions over retributive justice through criminal trials. The prosecution of their nationals under U.S. law could undermine their sovereign decisions and unravel delicate efforts toward peace. …

The Institutions Of Exceptions: Justification In Trade And Investment Treaties, Julian Arato

Michigan Journal of International Law

International economic law binds states in the interest of liberalizing markets, including in cross-border trade in goods and services (trade) and capital (investment). The treaty regimes for both trade and investment do this by disciplining states through legal rules, while preserving a modicum of governmental authority over domestic policy. The preservation of policy space in these regimes usually involves a process of exceptions-based justification – through formal exceptions clauses in most trade treaties and some investment agreements, and also through informal exceptions-style reasoning by adjudicators in the investment treaty regime more generally. This “exceptions paradigm” of justification has worked well …

Escape Probability: Rethinking Wartime Protection Of Nuclear Facilities, Pearle M. Lipinski

Michigan Journal of International Law

The 2022 Russian attacks on the Chernobyl and Zaporizhzhia nuclear facilities in Ukraine shocked the international community. Claims that the attacks constituted war crimes immediately entered the public consciousness, and a flurry of opinions were set forth on the international humanitarian law (“IHL”) protections afforded to nuclear plants, focusing on Article 56 of Additional Protocol I of the Geneva Conventions, which provides special protection to nuclear electrical generating stations. These opinions primarily focused on the immediate applicability and shortcomings of Article 56 on the attacks at hand, often operating on the presumption that a massively consequential environmental and humanitarian disaster …

Can – And Should – The Un Charter Be Saved?, Steven Ratner

Articles

World leaders from Canada’s Mark Carney to Germany’s Friedrich Merz have announced the demise of the international rules that provided some degree of order to international relations since the Second World War.2 The immediate cause is clear to them and others – a seeming abandonment of international law, and the UN Charter in particular, by the United States government, its chief architect and advocate. The U.S. actions and rhetoric over Venezuela and Iran – wars the United States has started – as well as Greenland and Ukraine seem to have confirmed the worst about the future of international law.

How The U.S. Constitution Shapes International Tax Law: Instrument Choice In Tax Agreements, Noam Noked, Young Ran (Christine) Kim, Reuven Avi-Yonah

Articles

The U.S. Constitution’s Treaty Clause, which requires Senate approval by a two-thirds vote for treaties, has significantly influenced the development of international tax law. This Article examines the implications of Senate supermajority requirements on bilateral and multilateral tax treaties and agreements, alternative instruments, relevant international tax standards, and global tax governance.

Historically, tax treaties have been approved exclusively as Article II treaties requiring Senate approval. The difficulty of entering into treaties with the United States has influenced the instrument choice and design of U.S. and international tax standards. To address this challenge, several U.S. and international tax reforms have employed …

International Declaration On Gender Apartheid And Its Destructive Consequences, Georges Abi-Saab, Belquis Ahmadi, Hala Alkarib, Waheeda Amien, Penelope Andrews, Zainah Anwar, Marzia Babakarkhail, Cecilia Bailliet, Manizha Bakhtari, Karima Bennoune, Laurence Boisson De Chazournes, Roya Boroumand, Terry Boullata, Charlotte Bunch, Rebecca J.

Other Publications

The Declaration is the result of an 18-month process of global consultation with leading experts, including a series of virtual consultations with women human rights defenders (WHRDs) from Afghanistan in spring 2025 and an in-person convening of United Nations (UN) experts, Afghan and South African WHRDs, civil society representatives, and international law experts at the University of Michigan Law School in September 2025.

This effort builds on the precedent of other experts’ declarations, signed on to by leading international legal and human rights experts, which were very influential in developing a human rights jurisprudence on a range of issues, and …

The Durability Of Protections Against Abuse At Interpol Amidst Rising Authoritarian Pressures, Kristina Daugirdas

Articles

Over centuries and across continents, authoritarian governments have demonstrated a large appetite for international cooperation to target political opponents across borders. In 1851, the “first modern police organization”—the Police Union of German States, whose members included Austria and Prussia—was established “with the express purpose of policing the political opposition of established autocratic regimes.” During the 1970s and early 1980s, military regimes in South America participated in a secret scheme known as Operation Condor to coordinate their efforts to suppress subversion. A recent analysis of twenty-nine “hard authoritarian” regional organizations found that twenty-five were engaged in police cooperation. The Shanghai Cooperation …

States As Gatekeepers In Global Governance, Kristina Daugirdas

Articles

Over the last several decades, private actors—corporations, philanthropic foundations, and non-governmental organizations—have increasingly contributed to the development and implementation of public international law. In some cases, private actors are developing standards that serve as substitutes for public regulation. In other cases, private actors have been “invited in” to public international organizations as funders, accredited observers and consultants, and even representatives of member states. According to one estimate, 56 percent of international organizations offered some form of access to private actors in 1990; two decades later, more than 90 percent did.

What we are witnessing, in other words, is the growing …

Citizen Shareholders: The State As A Fiduciary In International Investment Law, Eleanor L. Thompson

Michigan Law Review

International investment law provides stability for investors, helps capital flow across the globe, and can be a critical tool for sustainable development. This regime, however, has become increasingly controversial, in part due to its inability to reconcile investor obligations with competing human rights obligations. International investment treaties provide substantive guarantees to investors, including submission to binding arbitration in the event of breach. When found in breach of one of these guarantees, international investment arbitral tribunal awards are often in the hundreds of millions of dollars, potentially creating “regulatory chill” for states that may otherwise take affirmative action to protect human …

Retaliatory Taxation, Reuven S. Avi-Yonah

Law & Economics Working Papers

This paper discusses the Trump administration's potential use of section 891 and pending legislation to apply retaliatory taxes to foreign countries that impose "discriminatory or extraterritorial" taxation on US multinationals.

Exorcising Hobbes’S Ghost: A Future For Constitutional And International Law, Monica Hakimi

Michigan Law Review

A review of Law for Leviathan: Constitutional Law, International Law, and the State. By Daryl Levinson.

Was The Niit A Treaty Override?, Reuven S. Avi-Yonah

Law & Economics Working Papers

Three court decisions have recently addressed the interaction of the Net Investment Income Tax (NIIT) and US tax treaties. The issue was whether the treaty provided an independent basis for crediting a foreign tax against the NIIT, because no such credit is available under the Code. First, in Toulouse, the Tax Court held that there was no treaty based credit. Second, in Christensen, the Court of Federal Claims held that a treaty-based credit was available, distinguishing Toulouse. Third, in Bruyea, the Court of Federal Claims issued a broader opinion that allowed the credit. Importantly, Bruyea addressed an issue that was …

Double Standards In Un Political Bodies: Is Impartiality Possible?, Steven Ratner

Other Publications

The decisions of the UN’s political bodies would seem to represent the epitome of claims of double standards in the enforcement of international law. For even if we can accept that the members of the Security Council or the Human Rights Council (HRC) will choose to bring some situations to the attention of those bodies while leaving others off the agenda, or to pass some resolutions and reject others, such decisions seem quite suspect if we view those organizations as not merely making policy but enforcing international law. International lawyers have long identified this dilemma over enforcement: is it better …

Should The United States Abandon Citizenship-Based Taxation?, Reuven S. Avi-Yonah

Law & Economics Working Papers

President Trump proposed during the election campaign to end the "double taxation" of American citizens living overseas. To which the answer is, what double taxation? Americans living overseas already benefit from three significant provisions that in most cases prevent any double taxation, and because of these most of them do not have any U.S. tax liability. Those who do are typically wealthier, derive income from investments or from high wages, and are not subject to foreign tax because they live in tax havens or in countries that do not tax rich immigrants on foreign source income, and they do not …

Confronting Catastrophic Risk: The International Obligation To Regulate Artificial Intelligence, Bryan Druzin, Anatole Boute, Michael Ramsden

Michigan Journal of International Law

While artificial intelligence (“AI”) holds enormous promise, many experts in the field are warning that there is a non-trivial chance that the development of AI poses an existential threat to humanity. Existing regulatory initiatives do not address this threat but instead merely focus on discrete AI-related risks such as consumer safety, cybersecurity, data protection, and privacy. In the absence of regulatory action to address the possible risk of human extinction by AI, the question arises: What obligations, if any, does public international law impose on states to regulate its development?

At present there is no scientific consensus as to the …

The Allure Of Trade And Sustainable Development Chapters, Jeesae Kim

Michigan Journal of International Law

Beginning in 2011, the European Union (“EU”) began to include independent Trade and Sustainable Development (“TSD”) chapters in its trade agreements. These chapters seek to protect international labor standards, environmental laws, and corporate social responsibility practices within the scope of the EU’s trade agreements. Trading states that sign onto TSD chapters are meant to engage in ongoing dialogue regarding the substantive commitments outlined in the chapters. If one of the states fails to uphold its substantive commitments, the other state may invoke a unique enforcement mechanism contained within TSD chapters. But unlike arbitration proceedings for non-TSD trade disputes, the TSD …

Rewriting Precedent: How International Adjudicators Influence Compliance, Jeffrey Kucik, Lauren Peritz, Sergio Puig

Michigan Journal of International Law

International cooperation depends on adaptation to changing conditions. International dispute settlement bodies can play a key role in maintaining cooperation over time. Evidence suggests that when legal bodies successfully adapt the law through the reinterpretation of rules, they can promote state compliance. However, this process is incremental and may not happen quickly enough, which can lead to backlash against international courts. In this article, we analyze these dynamics at the World Trade Organization (“WTO”), the global institution regulating international trade. Relying on data and case studies, we show how the Appellate Body modified its interpretations to promote compliance. Because this …

Economic Sanctions As Legal Ordering, J. Benton Heath

Michigan Journal of International Law

This article recovers a critical episode in the history of economic sanctions and considers its implications for international legal order. Beginning in 1905, a group of Chinese citizens launched a series of protests targeting American, British, and Japanese goods. These boycotts caused economic damage, disrupted international relations, and at times won significant political victories. At the same time, they captured the imaginations of peace advocates, lawyers, and scholars, who saw in the boycotts either a fundamental threat to legal ordering, a promising avenue for enforcing interstate peace, or, most radically, an engine for new kinds of political organization outside the …

An Ecofeminist Approach To Climate Risks, Angela Hefti

Michigan Journal of International Law

Climate change poses significant risks to the human right to life. However, international adjudicators have either neglected to examine right to life claims in the context of climate risks or dismissed them as prospective and speculative. International human rights bodies have long applied the standard of imminence to determine whether a threat to the right to life exists and the extent to which it constitutes a violation. In climate change cases, this standard has hardened, requiring a tight temporal connection between climate risks and a violation of the right to life. This article argues that failing to recognize the impact …

Transparency, Accountability, And Influence In The International Investment Law System, Jarrod Wong, Jason Yackee

Michigan Journal of International Law

This article offers the first interdisciplinary critique of transparency in international investment law (“IIL”) that draws on transparency-skeptical and accountability scholarship in political science and public administration. Not only has the expansive IIL literature overlooked these disciplines, but much of it fails to define the core concept of transparency. Building on contributions from the fields of administrative law, international relations, and system theory in classic political science, we provide a novel functionalist account of transparency that traces a line from transparency to accountability to influence in the IIL system.

We make three arguments. First, transparency involves access to data that …

Automating International Human Rights Adjudication, Veronika Fikfak, Laurence R. Helfer

Michigan Journal of International Law

International human rights courts and treaty bodies are increasingly turning to automated decision-making (“ADM”) technologies to expedite and enhance their review of individual complaints. These tribunals have yet to consider many of the legal, normative, and practical issues raised by the use of different types of automation technologies for these purposes. This article offers a comprehensive and balanced assessment of the benefits and challenges of introducing ADM into international human rights adjudication. We argue in favor of using ADM to digitize documents and for internal case management purposes and to make straightforward recommendations regarding registration, inadmissibility, and the calculation of …

Crisis And Change At The United Nations: Non-Amendment Reform And Institutional Evolution, Oona A. Hathaway, Maggie M. Mills, Heather Zimmerman

Michigan Journal of International Law

The Security Council’s inaction in response to the wars in Gaza and Ukraine has once again put a spotlight on structural problems at the United Nations (“U.N.”). Security Council paralysis—particularly the (mis)use of the veto power afforded to the permanent five (“P5”) members of the Council—has long prompted calls for reform. Yet the same veto power prevents nearly all efforts to reform the organization through the formal amendment process provided in the U.N. Charter.

This article argues that there is an alternative way forward: what we call “non-amendment reform.” Rather than seek formal amendments that are unlikely to survive the …

Pave Outer Space And Put Up A Parking Lot: Lagrange Points Should Be The Common Heritage Of Mankind, David A. Koplow

Michigan Journal of International Law

Outer space offers a vast array of opportunities, with different locations or regions available for exploitation by diverse users for a growing variety of satellite functions. But not all sectors of space are equally valuable for all applications, and the most desirable venues can become crowded, affording a premium for those who gain access first and impeding the development of a fair and efficient all-inclusive international legal regime.

This article focuses on Lagrange points, a finite series of special locations in space where the gravitational forces from a pair of large celestial bodies interact in unusual ways. These points afford …

Man On Mars: How Can International Space Law Limit The Environmental Consequences Of The Coming Rush For Resources In Space, Elizabeth Anne Henderson

Michigan Journal of International Law

The body of international law governing space has stood at a standstill for decades. The five central treaties regulating this area of law are not only vague, but they have also become a hindrance to the global community’s ability to address the rapidly intensifying second space race. The treaties do not adequately state who space belongs to, who is entitled to take advantage of the natural resources of celestial bodies, or what protections are afforded to celestial environments in the face of impending mining and resource extraction projects. This impasse within international law has not stopped entrepreneurs and corporations from …
