The Influence of Amicus Curiae Briefs on U.S. Supreme Court Opinion Content

We address fundamental questions about the ability of interest groups to shape public policy by examining the influence of amicus curiae briefs on U.S. Supreme Court majority opinion content. We argue that the justices will incorporate language from amicus briefs into their opinions based on the extent to which the amicus briefs contribute to their ability to make effective law and policy. Using plagiarism detection software and other forms of computer assisted content analysis, we find that the justices adopt language from amicus briefs based primarily on the quality of the brief's argument, the level of repetition in the brief, the ideological position advocated in the brief, and the identity of the amicus. These results add fresh insight into how interest groups influence the development of federal law by the Supreme Court.     

Friends You Can Trust: A Signaling Theory of Interest Group Litigation Before the U.S. Supreme Court

How do interest groups influence U.S. Supreme Court justices to vote in favor of their preferred outcomes? Following prior research on the influence of the Solicitor General, we develop and expand on the signaling theory of interest group influence via amicus curie briefs. We argue that an interest group's ideological reputation and the nature of the ideological signal it sends in its brief both function as powerful heuristics that convey information to the justices depending on the justices' own ideological preferences. When an organization files an amicus brief advocating for an outcome seemingly contrary to its traditional preferences (i.e., an unexpected signal), this signal should be more noticeable and credible than a signal in accordance with a group's conventional views (i.e., an expected signal). However, unexpected signals should have greater influence on justices who share the brief filer's preferences. We test our signaling theory on the terms from 1991 through 2002. We find that unexpected signals (but not expected signals) are associated with Supreme Court voting, and the influence of unexpected signals appears to be particularly strong among justices who share the ideological preferences of the brief filer.     

Interest Group Participation, Competition, and Conflict in the U.S. Supreme Court

In this article, we analyze how pluralistic, competitive, and conflictual interest group amicus curiae participation is in the U.S. Supreme Court. Examining participating organizations and briefs during the 1995 term, we address three inquiries. First, we scrutinize the types of organized interests who participate as amici curiae. We find that the Court is open to a wide array of interests and that particular types of groups do not dominate amicus activity. Second, we analyze the frequency with which amici file briefs on opposing sides of dispute. We reveal few strict patterns of competition, suggesting that Supreme Court cases are salient to a diverse spectrum of interest groups, many of which are not usually thought of as being in competition with one another. Third, we investigate how often and which amici directly cite one another for purposes of invalidating each other's argumentation. While amici have a great deal of opportunity for this form of direct conflict, it is surprisingly rare. Nonetheless, when amici engage in this express form of discord, they play a clear role in shaping the flow of information at the Court.     

多数主义的法院:美国联邦最高法院司法审查的性质

长期以来,美国联邦最高法院的司法审查虽被视为法治和人权的捍卫者,却被作为民主的对立面.结果,它在理论上陷入难以自拔的合法性困境,或者说"反多数难题".本文结合法律和政治学者的讨论,考察美国司法审查的现实图景,指出它具有很强的"多数主义"性质.具体表现为,多数司法判决符合当下多数公众的意见,最高法院这一机构和司法审查这一制度获得多数民众的持久认同;不但如此,司法审查能够在一定程度上回应公众意见,从而在较长时段与主流意见的变迁保持一致.这种"多数主义"的性质,是由法官自身对公众意见的关注和尊重、其他部门和公众对宪法含义的争夺以及法官任命体制等外在制衡,共同促成和保障的.美国联邦最高法院在与其他机构的竞争合作中动态地表达民意,它受制于民主过程,也塑造民主过程.在此意义上,司法审查是美国民主体制的一部分,具有民主合法性.对于"反多数难题"的讨论而言,真正的问题不是司法审查是否符合"民主",而是现有的民主理论是否符合政治现实.     

Passing and Strategic Voting on the U.S. Supreme Court

Analyzing strategic aspects of judicial decisionmaking is an important element in understanding how law develops. In this article, we examine sophisticated voting on the U.S. Supreme Court by empirically modeling justices' decisions to pass when it is their turn to vote during conference discussions. We argue that, due to the opinion assignment norm, the chief justice may pass when one of the key conditions necessary for sophisticated voting—certainty about the views held by other justices and the agenda—is lacking. By passing, the chief can view his colleagues' votes in order to determine which vote will allow him to assign the majority opinion and, ultimately, forward his policy preferences. Using data from Justice Lewis F. Powell's conference notes, we show that the chief passes for this purpose, and that doing so is an effective strategy. In addition, we show that the senior associate justice in a case, who has a nontrivial chance of assigning the majority opinion, also passes for strategic reasons. As we expect, the data indicate that the remaining associates seem not to pass for strategic purposes.     

The Use of Rhetorical Sources by the U.S. Supreme Court

This study considers whether U.S. Supreme Court justices use opinion content strategically, to enhance the legitimacy of case outcomes. This hypothesis is tested by examining the Court's use of rhetorical sources, which are references to esteemed figures and texts that corroborate the justices' views. The data are consistent with the position that justices use rhetorical sources strategically, citing them when the legitimacy of their actions is lowest, such as when they are overturning precedent, invalidating state or federal law, or issuing directives from a divided bench. The study also tests several other explanations for the use of these sources, such as legal considerations, the justices' ideologies, and efficiency concerns.     

Executive Branch Socialization and Deference on the U.S. Supreme Court

Are Supreme Court justices with prior experience in the executive branch more likely to defer to the president in separation of powers cases? While previous research has suggested that such background may signal judicial policy preferences but does not shape them, I argue here that institutional socialization may indeed increase future judicial deference to the president. Using an original data set of executive power cases decided between 1942 and 2007, I model justice‐votes to test this hypothesis. I uncover three noteworthy findings: (1) a clear correlation between prior executive branch experience and support for the executive branch, (2) the degree of this support intensifies as executive branch tenure increases, a finding congruent with a socialization hypothesis, and (3) contrary to received wisdom, executive powers cases possess a clear ideological dimension, in line with the expectations of the attitudinal model.     

Justices and Legal Clarity: Analyzing the Complexity of U.S. Supreme Court Opinions

Legal clarity is important to understand and measure because of its connection to the rule of law. We provide the first systematic examination of the clarity of Supreme Court opinions and discover five important results. First, certain justices systematically craft clearer opinions than others. Justices Scalia and Breyer write the clearest opinions, while Justice Ginsburg consistently writes the most complex opinions. Second, ideology does not predict clarity in majority or concurring opinions. Third, all justices write clearer dissents than majority opinions, while minimum winning coalitions produce the clearest majority opinions. Fourth, justices across the board write clearer opinions in criminal procedure cases than in any other issue area. Finally, opinions that formally alter Court precedent render less clear law, potentially leading to a cycle of legal ambiguity.

Collegial Influence and Judicial Voting Change: The Effect of Membership Change on U.S. Supreme Court Justices

Understanding the source of voting changes by appellate judges provides an important window into the factors that shape the votes of the judges more generally. We argue that membership changes, by altering the collegial context in which judges make their choices, affect the information environment, long-term collegial considerations, and short-term strategic calculations. As a result, membership change should lead to greater uncertainty and more frequent voting changes among continuing justices in the term following a replacement. We test this proposition by looking at vote change by justices of the U.S. Supreme Court in two separate analyses: justices' votes on search-and-seizure cases since Mapp v. Ohio (1961) and on the progeny of Miranda v. Arizona (1966) . Our results support the argument that the collegial context helps explain changes in voting choices. Our analysis suggests that collegial considerations are an important component of judges' behavior and merit further evaluation in a cross-national context.     

The European Court of Human Rights,Amicus Curiae,and Violence against Women

Are international courts and advocacy group legal mobilization shaping human rights politics? This question poses a theoretical and empirical challenge to state dominated understandings of international litigation. This article theorizes the interaction between advocacy groups and the European Court of Human Rights and the role this participation plays in the enforcement and development of human rights. The analyses examine institutional factors shaping broad trends in mobilization complemented by two in depth studies examining a single mode of participation, amicus curiae and a single area of law, violence against women. The data identify the critical role standing rules, court review powers and group expertise play in transnational rights mobilization and development. The findings bring into question dominant understandings of international law and contribute to a more complex understanding of law in a global age where international courts and societal actors are shaping the direction of rights protection.
