How do ideological factors explain the citation patterns of federal courts? Current literature uses citation data in myriad ways but leaves open the question of how ideological factors may influence citation from each level of the judicial hierarchy differently. Combining original data on citations to Supreme Court opinions by district courts from 1969 to 2005 with existing data on citations by the courts of appeals and Supreme Court, I present a more complete portrait of the scope of a precedent across the federal judiciary. I find that ideological factors are associated with differences in citing behavior on the federal courts. Both the appellate and district courts are responsive to Supreme Court precedent, but district courts are not equally responsive to liberal and conservative updates to doctrine. Further, as the Supreme Court ideology changes from the time of setting precedent, appellate courts are less likely to cite the precedent, but district courts cite it more. These results suggest that the relationship between ideology and precedent adherence is complicated by the distinct institutional features of the Supreme Court, courts of appeals, and district courts.

To compare court decisions in a systematic way, it is typically necessary to first read these decisions and then apply legal methods to them. Measurement models that support analysts in this manual labor usually rely on judges’ voting records. Since these data are often not available, we instead propose a latent-variable model that uses the widely available references in court decisions to measure the decisions’ latent position in their common case-space. We showcase our model in the context of forum shopping and forum selling of Germany’s lower courts.

Recent literature on writing style in US Supreme Court opinions has focused on style as a means of furthering justices’ policy goals. In particular, an opinion’s clarity is proposed to make the implementation of the announced policy more likely. We give a formal argument that the observed distribution of opinion clarity is not easily reconcilable with justices who are striving to write clearly in service of policy implementation-related goals; this is true even if there are case-level costs that sometimes make writing clearly more difficult. We propose that justices having aesthetic preferences – essentially, stylistic preferences over opinion language that are unrelated to policy implementation – that they weight heavily could explain the observed distribution of opinion clarity. Our analysis of some 4,500 majority opinions 1955–2008 is largely consistent with our theoretical argument.

Do inferior courts play a meaningful role in interbranch disputes between the judicial and other branches? In interbranch conflicts involving the judiciary, lower courts move first and may shape the direction of conflict before high courts intervene directly. This paper explores how this organizational feature affects the judiciary’s ability and willingness to constrain other branches, developing a formal model of an interbranch dispute involving a hierarchical judicial branch. The model demonstrates multiple mechanisms through which lower court decisions may alter the outcomes of interbranch disputes and explores when lower courts will initiate conflict with the other branches.

This study investigates how citizens assess the credibility of constitutional experts on matters of government authority. Analyses of data from two similarly designed experiments, conducted with national samples, reveal that partisanship, race, and level of education are significant predictors of survey respondents’ willingness to extend credibility to constitutional experts. The compatibility of the views expressed by experts with respondents’ own policy views on issues that are the subject of proposed government action is also important. Evidence shows that this consistency is more important in the decision that experts are credible than in decisions that they are not credible, suggesting that esteem motives are relevant in the decision to credit experts who express views congenial to our own that are distinct from social-identity motives scholars have theorized to be important in partisan resistance to expertise. The implications of findings for holding government officials accountable to constitutional limits on government authority are considered.

Justice Ruth Bader Ginsburg’s death near the end of the Trump presidency set off a fight in which Republicans moved to rapidly replace her over Democrats’ objections. I use a survey that was in the field at the time to assess whether this period affected the Court’s legitimacy. I find that Democrats who responded in the days just after Justice Ginsburg’s death saw the Court as less legitimate than those who responded shortly before it. These findings connect to broader questions about the sources of Court legitimacy, the mechanisms through which it changes, and the impact of contestation over appointments.

Law clerks hold immense responsibilities and exert influence over the judges they work with. However, women remain underrepresented in these positions. We argue that one reason for this underrepresentation is that – like potential political candidates – female law students may have lower levels of ambition compared to men. Using a survey of student editors at thirty-three top law reviews, we find that there is a gender gap in ambition for clerkships with the Supreme Court and Federal Courts of Appeal. Examining potential sources of this difference, we find that while women view themselves to be just as qualified for these positions as men, men are more willing to apply with lower feelings of qualification. Likewise, while women and men report similar levels of encouragement, more encouragement is required before women express ambition to hold these posts. The findings presented here have implications for research on judicial politics, political ambition, and women’s representation.

The Court of Justice of the European Union (CJEU) uses a chamber system to more efficiently decide cases. To what extent, and under what conditions, does the CJEU’s chamber system undermine the consistency of the Court’s application of EU law? This paper contributes to the literature on the internal organization of collegial courts by presenting a computational formal model that predicts (a) that hearing cases in smaller chambers undermines the consistency of the Court’s application of EU law and (b) that the magnitude of this effect is larger when judges’ preferences are more heterogeneous and smaller when plaintiffs strategically bring cases. Based on these findings, I use machine learning and empirical data on CJEU judgments in infringement cases to estimate the degree to which we should expect the chamber system to undermine the consistency of the CJEU’s application of EU law in practice.

Research of judges and courts traditionally centers on judgments, treating each judgment as a unit of observation. However, judgments often address multiple distinct and more or less unrelated issues. Studying judicial behavior on a judgment level therefore loses potentially important details and risks drawing false conclusions from the data. We present a method to assist researchers with splitting judgments by issues using a supervised machine learning classifier. Applying our approach to splitting judgments by the Court of Justice of the European Union into issues, we show that this approach is practically feasible and provides benefits for text-based analysis of judicial behavior.

How do judicial techniques enable courts to have a very effective impact on actual national policy while avoiding making binding decisions? Previous academic studies have focused mostly on the controversial capacity (and willingness) of courts to intervene in a country’s policy through statutory interpretation or authoritative decisions. We show that by refraining from sweeping landmark decisions, courts can have a latent but substantial impact on actual national policy through technical and procedural measures. The case study here is the Israeli immigration policy toward a large group of Palestinian litigants (916 petitions) who claim to be neglected security-related collaborators.
