Political scientists—primarily in the discipline’s international relations subfield—have long studied international law. After considering how political scientists and legal scholars define international law, this article identifies five stages of political science research on international law, including the current interdisciplinary international law and international relations (IL/IR) stage, and it reviews three trends in political science research that constitute an emerging sixth stage of interdisciplinary scholarship: a law and world politics (L/WP) stage. First, moving beyond the “IL” in IL/IR scholarship, international relations scholars are increasingly studying domestic law and domestic courts—not only their foundational role in supporting international law and international courts but also their direct role in core areas of international relations, including international conflict and foreign policy. Second, moving beyond the “IR” in IL/IR scholarship, political scientists are adapting their research on international law to the broader world politics trend in political science by studying types of law—including extraterritoriality, conflict of laws, private international law, and the law of transnational commercial arbitration—that govern the transnational activity of private actors and can either support or hinder private global governance. Third, moving beyond the domestic-international divide, political scientists are increasingly rejecting “international law exceptionalism,” and beginning to take advantage of theoretical convergence across the domestic, comparative, and international politics subfields to develop a better general understanding law and politics.
John Stuart Mill is a liberal icon, widely praised in particular for his stirring defense of freedom of speech. A neo-Millian theory of free speech is outlined and contrasted in important respects with what Frederick Schauer calls “the free speech ideology” that surrounds the First Amendment of the U.S. Constitution, and with Schauer’s own “pre-legal” theory of free speech. Mill cannot reasonably be interpreted to defend free speech absolutism if speech is understood broadly to include all expressive conduct. Rather, he is best interpreted as defending an expedient policy of laissez-faire with exceptions, where four types of expression are distinguished, three of which (labeled Types B, C, and D) are public or other-regarding, whereas the fourth (labeled Type A) is private or self-regarding. Types C and D expression are unjust and ought to be suppressed by law and public stigma. They deserve no protection from coercive interference: they are justified exceptions to the policy of letting speakers alone. Consistently with this, a moral right to freedom of speech gives absolute protection to Type B public expression, which is “almost” self-regarding. Type A private expression also receives absolute protection, but it is truly self-regarding conduct and therefore covered by the moral right of absolute self-regarding liberty identified by Mill in On Liberty. There is no need for a distinct right of freedom of expression with respect to self-regarding speech. Strictly speaking, then, an expedient laissez-faire policy for public expression leaves the full protection of freedom of private expression to the right of self-regarding liberty.
An important application of the neo-Millian theory relates to an unjust form of hate speech that may be described as group libel. By creating, or threatening to create, a social atmosphere in which a targeted group is forced to live with a maliciously false public identity of criminality or subhumanity, such a group libel creates, or significantly risks creating, social conditions in which all individuals associated with the group must give up their liberties of self-regarding conduct and of Type B expression to avoid conflict with prejudiced and belligerent members of society, even though the libel itself does not directly threaten any assignable individual with harm or accuse him or her of any wrongdoing of his or her own. This Millian perspective bolsters arguments such as those offered by Jeremy Waldron for suppressing group libels. America is an outlier among advanced civil societies with respect to the regulation of such unjust hate speech, and its “free speech ideology” ought to be suitably reformed so that group libels are prevented or punished as immoral and unconstitutional.

The Supreme Court’s docket consists of thousands of cases each term, with petitioners hoping at least four justices will be compelled to grant review to their case. The decision to move a case from their docket to their calendar for oral arguments and all intermediate steps is what is known as the agenda-setting process. This is a fundamental step in the judicial process, as the Supreme Court cannot establish precedent and affect policy change without first deciding to review.

Reparations are among the most tangible, victim-centric, and personal of processes in the transition from violence to peace, symbolizing the recognition that an individual has been harmed and has rights in the eyes of the state or international community. Reparations are also an inherently political project, transforming official visions of violence, responsibility, and victimization into material and psychological benefit. Despite the power of reparations to shape transitions from violence to peace, they have been too often ignored in practice, leaving most victims of gross violations of human rights and serious violations of international humanitarian law without reparation. Partly as a consequence, research has tended to focus more on “harder” processes, like trials and truth commissions, than on the “stepchild of postconflict justice.” Yet, there have been significant developments in reparations theory and practice that motivate key outstanding questions for researchers.
Reparations derive their symbolic power from the law, which is an imperfect tool for responding to the varied forms of violence experienced in conflict and to the diverse, sometimes contradictory, priorities and needs that people hold. In such contexts, there is an inherent tension between expanding reparations programs to be inclusive and adaptable and preserving their fundamental distinction as a justice process. This is a difficult balance to strike, but there are frameworks and questions that can offer useful guidance. In particular, the lenses of economic violence and positive peace are useful for articulating the role of reparations in postconflict transitions, offering conceptual expansion beyond transitional justice’s traditional concern for political violence without delving too far into the customary terrain of development or postconflict reconstruction.
Yet, the specific mechanisms through which the inward and outward feelings and attitudes and broader social changes that reparations are expected to produce remain undertheorized in transitional justice scholarship, in large part because of a lack of empirical evidence about how recipients experience them in practice. Does the restoration of civic trust, for example, depend upon recipients of individual reparations telling their neighbors about their payments? Does recognition as a citizen depend upon a beneficiary publicly self-identifying as a victim? Questions like these about the particular variables that drive reparations outcomes represent the next frontier for transitional justice researchers interested in the role of reparations in the transition from violence to peace.
Research on constitutional law has come in different waves mirroring the development of states in recent decades. While the decolonization period of the 1960s still kept the old ties of constitutional “families,” comparison based on such ties has become ever less persuasive since the 1980s wave of constitution making following the fall of the Berlin Wall. Research about de facto and de jure constitutional law now tends to embrace institutional details like judicial review powers and procedures of direct democracy. The field of comparative constitutional law is controversial both in methods and substance. It still lacks a consistent framework of comparative tools and is criticized as illegitimate by scholars who insist on the interpretive autonomy within each constitutional system.
Research in the area of fundamental rights has to deal with long-lasting controversies like the constitutionality of the death penalty. Bioethical regulation is another new field where constitutional positions tend to diverge rather than converge. Embryonic stem cell research, therapeutic cloning, pre-implantation genetic diagnosis, and surrogate motherhood are examples from biotechnology and reproductive medicine where constitutional scholars disagree about what, if anything, constitutional law can contribute to provide a basis or limit for regulation. With the worldwide rise of constitutional courts and judicial review, the standards for the interpretation of fundamental rights become more important. Legal scholarship has worked out the differences between the rule-oriented approach associated with Anglo-American legal systems versus the principle-based approach common to continental Europe.
Existing theories of international law are largely state-centric. While international cooperation can benefit all, states are often tempted to violate their promises in order to manage economic and political crises. States must accordingly balance enforcement against flexibility: legal institutions must provide enough enforcement that states comply most of the time yet also provide enough flexibility that states can violate during crises. Such a balance is possible when laws are crafted and enforced by unitary actors that will tolerate occasional violations by others in order to preserve their own right to occasionally violate.
However, the changing doctrine of sovereign immunity has dramatically transformed the actual practice of international law. Non-state actors and domestic courts play an increasingly important role in challenging state legal violations, generating a divergence between the theory and practice of contemporary international law. This divergence is apparent in many issue areas, including terrorism, human rights, sovereign debt, and foreign investment. This divergence suggests that political scientists and legal scholars must reconsider the limits of state-centric theories and examine the role of non-state actors and domestic courts.

Armed conflict is ultimately about the violent confrontation between two or more groups; however, there is a range of behaviors, both violent and nonviolent, pursued by governments and rebel groups while conflict is ongoing that impacts the course and outcomes of that violence. The use of judicial or quasi-judicial institutions during armed conflict is one such behavior. While there is a well-developed body of literature that examines the conditions under which governments engage with the legacies of violence following armed conflict, we know comparatively little about these same institutions used while conflict is ongoing.
Similar to the use of transitional justice following armed conflict or post-conflict justice, during-conflict transitional justice (DCJ) refers to “a judicial or quasi-judicial process initiated during an armed conflict that attempts to address wrongdoings that have taken or are taking place as part of that conflict” (according to Loyle and Binningsbø). DCJ includes a variety of institutional forms pursued by both governments and rebel groups such as human rights trials, truth commissions or commissions of inquiry, amnesty offers, reparations, purges, or exiles.
As our current understanding of transitional justice has focused exclusively on these processes following a political transition or the termination of an armed conflict, we have a limited understanding of how and why these processes are used during conflict. Extant work has assumed, either implicitly or explicitly, that transitional justice is offered and put in place once violence has ended, but this is not the case. New data on this topic from the During-Conflict Justice dataset by Loyle and Binningsbø suggests that the use of transitional justice during conflict is a widespread and systematic policy across multiple actor groups. In 2017, Loyle and Binningsbø found that DCJ processes were used during over 60% of armed conflicts from 1946 through 2011; and of these processes 10% were put in place by rebel groups (i.e., the group challenging the government rather than the government in power).
Three main questions arise from this new finding: Under what conditions are justice processes implemented during conflict, why are these processes put in place, and what is the likely effect of their implementation on the conflict itself? Answering these questions has important implications for understanding patterns of government and rebel behavior while conflict is ongoing and the impacts of those behaviors. Furthermore, this work helps us to broaden our understanding of the use of judicial and quasi-judicial processes to those periods where no power shift has taken place.

We summarize the formal theoretical literature on Supreme Court decision-making. We focus on two core questions: What does the Supreme Court of the United States do, and how can one model those actions; and, what do the justices of the Supreme Court want, and how can one model those preferences? Given the current state of play in judicial studies, these questions then direct this survey mostly to so-called separation of powers (SOP) models, and to studies of a multi-member (“collegial”) court employing the Supreme Court’s very distinctive and highly unusual voting rule.
The survey makes four main points. First, it sets out a new taxonomy that unifies much of the literature by linking judicial actions, modeling conventions, and the treatment of the status quo. In addition, the taxonomy identifies some models that employ inconsistent assumptions about Supreme Court actions and consequences. Second, the discussion of judicial preferences clarifies the links between judicial actions and judicial preferences. It highlights the relationships between preferences over dispositions, preferences over rules, and preferences over social outcomes. And, it explicates the difference between consequential and expressive preferences. Third, the survey delineates the separate strands of SOP models. It suggests new possibilities for this seemingly well-explored line of inquiry. Fourth, the discussion of voting emphasizes the peculiar characteristics of the Supreme Court’s voting rule. The survey maps the movement from early models that ignored the special features of this rule, to more recent ones that embrace its features and explore the resulting (and unusual) incentive effects.

Crucial to understanding the behavior of judges and the outputs of courts is the institutional context in which they operate. One key component of courts’ institutional structure is that the judiciary is organized as a hierarchy, which creates both problems and opportunities for judges. For instance, one problem for judges at the top of a hierarchy is how to best exercise oversight of lower court judges, whose decisions are often not reviewed by higher courts. One opportunity is that higher courts can reverse errors by lower courts; another is that, as new legal issues emerge, hierarchy provides opportunities for judges to learn from one another.
Scholars of the judicial hierarchy have pursued two broad approaches. The “team perspective” begins by assuming that all judges in a hierarchy have the same values or principles, and thus care only about achieving the correct outcome in a given case. In the team approach, the key problem in adjudication is informational. All judges agree on the correct outcome of a case, conditional on understanding the relevant facts, but may lack this understanding due to resource constraints or informational advantages enjoyed by litigants. The agency approach, by contrast assumes that judges in the hierarchy have differing preferences, and the key problem is how higher courts can ensure compliance by lower courts.
Despite these different foundational assumptions, the team and agency approaches have both been employed successfully to study core questions regarding the judicial hierarchy, including: why hierarchy exists; how higher courts can best oversee lower courts; how learning takes place both within and across the levels of the judiciary; and how collegiality influences judicial decision-making. Yet, while our understanding of the judicial hierarchy has greatly increased in recent years, many questions remain, such as how judges learn and how to measure legal doctrine.

Even though most judges in the United States stand for election in the context of strong normative objections to the practice of electing judges, political scientists have produced a surprisingly thin theoretical framework for understanding how judicial campaigns affect voters. This paucity of research is particularly surprising given the increasingly politicized environment in which judicial elections operate. The literature on judicial campaigns is well-served to draw upon the well-trodden research about campaign effects for executive and legislative office. In some important respects, however, judicial contests differ from those for executive or legislative office. To this end, the Expectancy Theory pioneered by James L. Gibson provides an important theoretical development, emphasizing that the effects of judicial campaigns are highly conditional upon variation in voters’ willingness to tolerate different types of campaign activity. Moreover, the effects of campaigns are highly dependent on the context of both institutional design and voters’ own experiences with judicial elections.
