In Ending Judgment Arbitrage, Professor Shill claims that non-U.S. plaintiffs “routinely” practice a three-step strategy called “judgment arbitrage”: (1) selection of a foreign country to litigate the merits and obtain a favorable judgment; (2) selection of a “receptive” U.S. state to obtain judicial recognition of the foreign judgment; and (3) selection of a more “protective” U.S. state to obtain enforcement against defendant’s assets there (p. 470 & Figure 3). Shill argues that this practice is a problem, and uses law market theory to argue that new federal legislation is needed to solve it. Shill has written a fascinating article. To the extent judgment arbitrage exists, I agree that it would pose problems for both litigant fairness and interstate competition. In addition, Shill’s extension of law market theory to the law of foreign judgments is a valuable contribution. But Shill does little to show that judgment arbitrage actually exists, and he clearly fails to demonstrate that the practice is “routine” or otherwise significant enough to require a response from the United States Congress. In fact, the article does not identify a single real-world example of judgment arbitrage. Given that judgment arbitrage is highlighted in the article’s title, the focus of its law market analysis, and the raison d’être of its legislative proposal, this is a significant omission.

My article examines conduct that I call “unfriendly unilateralism”—where one state decides, outside any structured international process, to act unfriendly toward another. The economic measures that the United States and Europe are now taking against Russia in response to the Crimea situation are good examples. Likewise, before the U.N. Security Council authorized states to take a broad range of measures against Iran for its nuclear program, several states acted unilaterally. Such conduct is, in my view, undervalued in the legal literature. Most international lawyers either dismiss unfriendly unilateralism as power politics that fall outside the law, or analyze it as a tool for enforcing the law—that is, for pressuring the target state to comply with existing law. In either event, the conduct is widely understood to be regretful or ineffective. To the extent that the conduct is inconsistent with the acting state’s own obligations, it also is unlawful—unless, of course, the acting state is enforcing the law after having been injured by the target’s breach. My article’s descriptive claim is that unfriendly unilateralism can also play an important role in lawmaking. States variously use unfriendly unilateralism to: (1) preserve legal norms, (2) strengthen legal regimes by instigating stricter substantive standards or more rigorous oversight mechanisms, (3) reconcile competing objectives from different regimes, and (4) recalibrate regimes for changed circumstances. Of course, the idea that unilateral conduct can be juris-generative is not new; unilateral claims and counterclaims are a recognized part of the customary legal process. But when unilateralism is coupled with unfriendliness—that is, when the conduct is targeted at a specific state—international lawyers instinctively put on their enforcement lenses. They focus on how the conduct enforces existing law, not on how it helps make new law. For instance, several scholars have analyzed the unfriendly unilateralism against Iran as enforcement. Yet the acting states were using unfriendly unilateralism to support a broad and coordinated lawmaking effort. Their principal goal was to pressure Iran into accepting stricter substantive standards on nonproliferation and more rigorous oversight mechanisms. As the Iran example also demonstrates, unfriendly unilateralism is a fairly unique mode of lawmaking. Unlike in the ordinary customary process, a state that uses unfriendly unilateralism usually does not model the new norm. Rather, its unfriendly (and sometimes unlawful) conduct pressures the target into accepting or helping to develop an entirely different norm. This makes unfriendly unilateralism a potentially versatile and potent lawmaking tool.

Other posts in this series can be found in the related posts below. Monica Hakimi’s Unfriendly Unilateralism is a very welcome addition to the growing body of literature on international lawmaking. Hakimi’s basic claim is that states often act unilaterally in ways that prompt changes to international law. She defines unilateral action as that which takes place outside the confines of the collective decision-making processes commonly associated with international lawmaking (p. 111). These unilateral actions can also work to the detriment of some states (hence, “unfriendly”). In the enforcement context, Hakimi argues, international law has long recognized a role for unfriendly unilateralism. Rules on countermeasures tell us when one state’s imposition of penalties on another state is excused. Hakimi’s article insightfully describes how the doctrinal focus on enforcement obscures and distorts the role that unilateralism can play in lawmaking. Hakimi makes two key points. First, descriptively, she argues that despite the focus on unilateralism’s role in relation to enforcement issues, states nevertheless use (often noncompliant) unilateral action to prompt changes in the law. Second, Hakimi argues that unilateral action can be good for international law. By overcoming the status quo bias that exists in collective decision-making procedures, unilateralism can allow the law to adapt to changed circumstances. Hakimi’s descriptive claim is very persuasive. In developing her argument, Hakimi does a wonderful job of exposing one of the central tensions in international law: that states are both international law’s subjects and its authors. International lawyers, scholars, and states must be mindful that states often have mixed motives when acting. Some noncompliant actions are simple cheating and can be addressed as such. States intend other noncompliant acts to be juris-generative, though. Treating these acts as run-of-the-mine noncompliance risks, among other things, underestimating how invested states are in using international law as a tool to enhance cooperation. Indeed, not only do states take unilateral action to prompt the law’s revision; they also build into international agreements devices that encourage unilateral action. Exit clauses, regime shifting, and soft law are common tools in states’ treaty-making practice that encourage renegotiation by permitting states to unilaterally depart from the legal status quo. As Hakimi very effectively documents, states’ resort to unilateralism—both when designing international agreements and after such agreements exist—can help circumvent the formal difficulties inherent in amending legal rules in a system in which all states must consent to their own legal obligations.
