Preface to the Fourth Edition
As professors who teach courses and conduct research on courts and law, we became increasingly frustrated with the absence of a comprehensive collection of information on the U.S. Supreme Court. It seemed that each time we needed even the simplest datum, whether it be a Senate vote on a particular nominee or the number of cases argued during a given term, we had to consult three or four different books and articles to find the desired information. This sense of frustration led to the compilation of the first edition of The Supreme Court Compendium: Data, Decisions, and Developments.
Our goal for this fourth edition is the same as it was for the first three: to provide a comprehensive collection of data and relevant information on the U.S. Supreme Court. We have attempted to cover as many bases as possible, from characteristics of the Court and its members, to the environment in which it operates, to the public's views on its decisions and perceptions about the Court itself, and much more. We have sought to provide readers with some insight into how we collected the data and why we consider them important. We urge readers to use both the general introduction and the introductions included with each chapter as guides to the information presented in the tables and figures that follow. Readers should also pay particular attention to table notes, where we identify data sources and, when relevant, caution readers about potential irregularities in data interpretation.
Of course, there are differences between this and the previous editions. First, we updated virtually every table. So, for example, readers will find a wealth of information on the personal and professional backgrounds of the Court's two newest members—John G. Roberts Jr. and Samuel A. Alito Jr. Moreover, we have retained the backdating included in the third edition. Such data will be of particular use to researchers who wish to conduct longitudinal analyses of the Court and its members; they now have highly reliable data for nearly six decades (1945–2004 terms). Second, we have strengthened what we think was the most distinctive feature of the first three editions—the emphasis on the Supreme Court of the United States. Accomplishing this goal led us to add (or rethink) several tables. New tables include information on the justices' participation in oral argument (with data generously provided by Tim Johnson), a more detailed depiction of the appointment process (with a new table on the actions of the Senate judiciary committee and a refined table covering Senate confirmations), and highly innovative estimates of the ideology of the justices by term (graciously supplied by Andrew Martin and Kevin Quinn).
In addition, given the dynamic nature of the data in this volume, CQ Press plans to roll out an online version of the Compendium in 2007. This will allow for more frequent updates, as well as for data downloads. Note, though, that because we were unable to include reliable data for the 2005 term in this edition, we will post those data on the project's Web site, at http://epstein.law.northwestern.edu/research/compendium.html. The data will remain there until CQ Press finishes the online version.
One final note about this edition: Putting it together required us to work with a great deal of data. Although we took pains to check and recheck all the tables, it is possible that we committed errors of omission and commission. Naturally, we take responsibility for both. We ask readers who find errors in the text or tables to please contact us so that we may remedy them for subsequent editions and for the online version. Please direct e-mail to Lee Epstein at http://email@example.com.
Many people assisted us in producing this and earlier editions of The Supreme Court Compendium. The folks at CQ Press were, as always, terrific. We initially pitched the project to Brenda Carter, who provided a great deal of encouragement. Our editor for the first edition, Jeanne Ferris, could not have been more helpful or patient. She read the entire text and considered all the tables with an eye toward clarity and readability. This edition continues to reap the benefits of Jeanne's keen interest. Kerry Kern returned as our copy editor, and Julia Petrakis repeated as indexer. Our thanks to them both for a job well done. We also appreciate the important contributions of the CQ staff who helped us with the new edition—Doug Goldenberg-Hart, Belinda Josey, January Layman-Wood, Steve Pazdan, Andrea Pedolsky, Paul Pressau, Anne Stewart, Kathryn Suarez, and Margot Ziperman.
We have terrific colleagues in the law and courts field—many of whom took the time to offer suggestions and even data, for this and earlier editions. We are especially indebted to Judy Baer of Texas A&M, Gregory Caldeira of Ohio State University, Micheal Giles of Emory University, Leslie Goldstein of the University of Delaware, Valerie Hoekstra of Arizona State University, Jack Knight of Washington University, Andrew D. Martin of Washington University, Jan Palmer of Ohio University, and James Stimson of the University of North Carolina.
Research assistants at our respective institutions performed various essential tasks throughout this undertaking. Since this edition builds on the first three, we want again to acknowledge a generation or two of our former students (many of whom are now professors): Ellen Baik, Scott Comparato, Paul Fabrizio, Marjorie George, Tracey George, Scott Graves, Chris Hasselman, Marc Hendershot, Robert Howard, Tim Johnson, Chad King, Madhavi McCall, Robert Oritz, Kirk Randazzo, Melissa Schwartzberg, [Page xvii]Eddie Sindaco, James Spriggs, and Jeff Staton. Ryan Black, Maxwell Mak, and Elyce Winters cheerfully gathered data and helped to assemble the final version of this edition. In addition, we are grateful to Paul Collins Andrew Koshner, Andrew Martin, Ryan Owens, Kevin Quinn, Rorie Spill, and Christina Wolbrecht, who have allowed us to use some of their data.
Although a four-person collaboration was a great deal of fun, it was our home institutions that bore the costs of extended phone calls and faxes, as well as photocopying and mailing expenses. We also thank the Law and Social Science Program of the National Science Foundation (NSF) for its support for our research on the Court, including Spaeth's U.S. Supreme Court Judicial Databases, Epstein and Walker's U.S. Supreme Court Justices Database, and Epstein, Segal, and Spaeth's digital archive of the Papers of Justice Harry A. Blackmun. Without NSF funding, this volume would be considerably less comprehensive.

About the Authors
Before the first edition of The Supreme Court Compendium was published in 1994, there was no comprehensive collection of data on the U.S. Supreme Court. This was unfortunate, not only because of the importance of the Court in the American government but also because the absence of reliable data makes it hard to understand the Court, the justices, and case decisions. This volume is our effort to rectify this deficiency.
We hope that readers will find useful the data and information presented in the following pages. Before continuing, though, we urge them to read this introduction and the introductions opening each chapter so that they might better understand the choices we made in compiling this work. Here, we provide information on data sources, the scope of the data, data presentation, and the overall organization of the volume. In the introductions preceding each chapter, we provide more specific details on the tables they contain.Data Sources and Scope of the Data
Our sources of information vary widely, depending on what dimension of the Court we are examining. The reports of the Court's decisions are the primary sources. The official record is the United States Reports.1 Three privately printed sources are also employed: The Lawyers' Edition,1The Supreme Court Reporter,1 and United States Law Week.1 In Tables 2-9 and 2-10 we provide additional information about these various systems. Two major legal electronic information retrieval systems, LEXIS-NEXIS and Westlaw, also contain the Court's decisions. We used these sources when gathering data requiring specific search delimiters. Other sources of electronically transmitted information are various Web sites (see Table 1-8). The Legal Information Institute site, for example, contains recent decisions of the Court.1
We also obtained information from archived databases. Harold J. Spaeth's U.S. Supreme Court databases1 focus on Supreme Court cases, providing a wealth of data beginning with the Vinson Court through to the present. Among the many attributes of the Court decisions coded by Spaeth are the names of the courts making the original decision, the identities of the parties to a case, the policy context of a case, and the votes of each justice. It and accompanying documentation are freely available at the Web site for the University of Kentucky's S. Sidney Ulmer Project: http://www.as.uky.edu/polisci/ulmerproject/sctdata.htm. Along with the Gallup Poll, the Harris Survey, and unpublished press releases issued by the New York Times, we use data gathered by the [Page xxii]National Opinion Research Center (and archived as the General Social Survey) as sources for information on public opinion. Because survey responses are extremely sensitive to question wording, we typically eschew one-time “snapshots” of public opinion on questions relevant to the judiciary and focus instead on trends over time.
We compiled additional data from government reports. Historical Statistics of the United States, Colonial Times to 1970,1 and the Statistical Abstract of the United States1 (published annually since 1878) are “the standard summar[ies] of statistics on the social, political, and economic organization of the United States.”1 For our purposes, they are particularly useful sources of Court caseload statistics. Another very helpful source is The Constitution of the United States of America: Analysis and Interpretation.1 Among other things, it lists all Court decisions overruled by subsequent decisions and all cases in which the Court held unconstitutional acts of federal, state, and local governments. We also rely on reports issued by various government actors and agencies. Examples include the Register of the U.S. Department of Justice and the Federal Courts,1 which provides information on individuals who have served as attorneys and solicitors general; the Administrative Office of the United States Courts,1 which issues annual reports on Court caseloads; and the Annual Report of the Attorney General of the United States,1 which contains various data on the processing of Court litigation. Such data are increasingly available via the Internet. When we obtained information from a Web site, we list the URL.
Finally, we scoured historical accounts and secondary material to fill in blanks and verify other sources. This was particularly the case in collecting information about the lives of the justices. While there has been a great deal written about the most famous of the justices, little is known about many of the others. Much of the data on the justices come from well-established biographical sources, including Leon Friedman and Fred Israel's The Justices of the United States Supreme Court,1 The Judicial Conference of the United States's Judges of the United States,1The National Cyclopaedia of American Biography,1 and The Dictionary of American Biography.1The First One Hundred Justices1 by Albert P. Blaustein and Roy M. Mersky was especially helpful. Similarly, a great deal of information was gleaned from John Schmidhauser's classic study of the backgrounds of the justices.1 Data from this important work are archived at the Inter-University Consortium for Political and Social Research.1 And Lee Epstein, Thomas G. Walker, and Nancy Staudt have now updated Schmidhauser's study, with their data housed in the U.S. Supreme Court Justices Database (http://epstein.law.northwestern.edu/research/justicesdata.html). Specifically, the database contains more than 300 variables, falling into four categories: background characteristics and personal attributes, nomination and confirmation, service on the Court, and departures from the bench. Nonetheless, even with [Page xxiii]the wealth of information contained in these sources, significant gaps remained. We filled these holes by consulting scores of biographies on the justices, newspaper accounts, and studies of the various historical periods. At the end of this process, we were still plagued with missing information and instances where contradictory claims in the biographical literature could not be resolved to our complete satisfaction. Unfortunately, such difficulties are inevitable when dealing with incomplete historical records. Notes to the tables alert readers to these and other problems.
The scope of our information also varies considerably. Whenever possible we tried to present data dating back to the Court's inception in February 1790. Unfortunately, this was more the exception than the rule, as such longitudinal data have seldom been compiled and, when they have, are often riddled with inconsistency. We were especially handicapped in our ability to offer information on voting behavior prior to the Vinson Court era, as our most reliable sources, Spaeth's Supreme Court databases, do not antedate 1946.
For data other than voting behavior, though, we were often able to locate information going back to the early 1900s and occasionally even the 1800s. We want to alert readers to the fact that, while we sought to verify historical data against other sources, we did not attempt to research the primary data sources. In some instances, therefore, we cannot vouch for accuracy. Once again, table notes alert readers to these potential problems.Presentation of the Data
Several major concerns guided our presentation of the data. First, we sought to be as comprehensive as possible. Accordingly, we provide data well fitted to tabular presentation as well as data that are not. Examples of the latter are a chronology of events in the Court's history (Table 1-1) and catalogs of landmark decisions (Tables 2-12 and 2-13). To organize and communicate the data in usable fashion, we exercised our judgment of how best to present them, as most of the data have either not been compiled at all or have not appeared in any systematic fashion. Where possible, we have conformed to customary and conventional categorization, such as chronological, alphabetical, or topical. But for the vast majority of the data, conventions simply do not exist. Hence, we proceeded on the bases of clarity and understanding.
Second, for those tables derived from the Spaeth databases, we wanted to provide sufficient information for readers to understand, evaluate, build on, or reproduce them. Accordingly, for each table we provide two crucial pieces of information—what Spaeth labels “analu” and “dec_type.” [Page xxiv]“Analu” is the unit of analysis under study, and Spaeth offers the following options:
- analu = 0: case citation. Sometimes the Court decides several cases under one opinion. Using this as the unit of analysis will identify only the lead case.
- analu = 1: docket number. In those instances when the Court decided several cases under one opinion, this unit of analysis will bring up all cases, not just the lead case. This can be useful when differences exist between or among cases consolidated under one citation, such as the court in which the case originated, the court whose decision the Supreme Court reviewed, the parties to the case, and so on.
- analu = 2: multiple-issue case. This is the identification of cases that contain multiple issues, such as a case that raised questions about federal taxation and self-incrimination.
- analu = 3: multiple legal-provisions case. This is the identification of cases that contain multiple legal provisions, such as a case in which the Court dealt with the Fourteenth Amendment Equal Protection Clause and the Civil Rights Act of 1964.
- analu = 4: split-vote case. This is the identification of cases that contain a split vote. This phrase refers to those cases with a common citation, docket number, legal provision, and issue in which one or more of the justices voted with the majority on one issue or aspect of the case and dissented on another.
- analu = 5: case with multiple issues and multiple legal provisions.
“Dec_type” refers to the types of decisions the Court renders. Again, Spaeth offers a number of options:
- dec_type = 1: cases in which the Court hears oral argument and which it decides by a signed opinion. These are the Court's so-called formally decided full-opinion cases.
- dec_type = 2: cases decided with an opinion but without oral argument—that is, per curiam.
- dec_type = 3: memorandum cases. These are summary decisions that deal with petitions for certiorari and appeals, requests of individuals and organizations to participate as amicus curiae, and various other motions, orders, and writs. These are segregated from other types of decisions by their location in the back of the various volumes of the United States Reports, beginning at page 801 or 901 or later.
- dec_type = 4: decrees. This infrequent type of decision usually arises under the Court's original jurisdiction and involves state boundary disputes. The justices will typically appoint a special master to take testimony and render a report, the bulk of which generally becomes the Court's decision. The presence of the label “decree” distinguishes this type of decision from the others.
- dec_type = 5: cases decided by an equally divided vote. When a justice fails to participate in a case or when the Court has a vacancy, the participating justices may cast a tie vote. In such cases the reports merely state that “the judgment is affirmed by an equally divided vote” and give the name of any nonparticipating justice(s). Their effect is to uphold the decision of the court whose ruling the Supreme Court reviewed.
- dec_type = 6: a variant of the formally decided cases (dec_type = 1). It differs from type 1 only in that no individual justice's name appears as author of the Court's opinion. Instead, these unsigned orally argued cases are labeled as decided per curiam. The difference between this type and type 2 is that the former includes oral argument, whereas the latter does not. In both types the opinion of the Court is unsigned—that is, per curiam.
- dec_type = 7: judgments of the Court. This decision type is also a variant of the formally decided cases (dec_type = 1). It differs from type 1 in that less than a majority of the participating justices agree with the opinion produced by the justice assigned to write the Court's opinion.
Readers can learn more about “analu” and “dec_type,” including which options to select for particular research projects, from at least two sources—Spaeth's documentation and Sara C. Benesh's “Becoming an Intelligent User of the Spaeth Databases,” both of which are available on the Internet at http://www.as.uky.edu/polisci/ulmerproject/sctdata.htm. We wish to note here that users need not select only one “analu” and one “dec_type.” Indeed, among the most common combinations appearing in our tables is one in which the unit of analysis equals case citation (analu = 0) and docket number (analu = 1), and the type of decision equals formally decided full-opinion cases, orally argued per curiams, and judgments of the Court (dec_type = 1, 6, or 7).
At the same time, while providing readers with sufficient information to replicate the tables, we sought to minimize the technical character of the data. This is not an easy task since the Court and its activities are complex matters typically characterized by a somewhat arcane vocabulary (notwithstanding the inroads made on legalese by the plain English movement of recent years). Although we eliminated technical terms to the extent possible, they are by no means absent. For this reason (and several others noted above), it is especially important that readers review the notes following the tables. Legal definitions typically lack even imprecise meaning. What rights, for example, are objectively within—or outside—“the very essence of a scheme of ordered liberty”?1 What principles of justice are [Page xxvi]“so rooted in the traditions and conscience of our people as to be ranked as fundamental”?1 Is a declaration of unconstitutionality or the overruling of a precedent beyond dispute? Moreover, many legal definitions create distinctions between things that arguably have no meaningful differences. A jurisdictional dissent, for example, includes dissents from the Court's refusal to decide a case, from the Court's affirmation of a lower court's decision without oral argument, and from the Court's assertion of jurisdiction over a case. None addresses the merits of the controversy. Should they be distinguished from one another or simply lumped together? Does it really matter? In short, we had to formulate our own operationally meaningful definitions, as the notes to the tables point out.
In addition, technical terms do not necessarily have conventional meanings. Jurisdictional dissents provide a good example, as do concurring opinions. Is a concurring opinion that fully agrees with the contents of the majority opinion to be treated the same as one that agrees only with the result reached by the majority? We do not think so; hence, we separate them into “regular” and “special” concurrences. In our view, the justices who join the former type are full-fledged members of the majority opinion coalition, while those joining the latter are not. And if enough justices specially concur, no opinion of the Court will result—only a judgment. In such a case, the decision provides little guidance either to the litigants or to others similarly situated. Consider also the basic question of how to count cases. Should each citation be treated separately, or should one count the number of docketed cases under a given citation? Further, should one limit analysis only to “formally” decided cases—that is, to those cases that have been orally argued? And if so, should orally argued cases with the prevailing opinion signed by a justice be included alone, or in tandem with those decided per curiam (in which no individual justice authors the prevailing opinion)? Because no convention dictates the answers to these and other matters, the explanatory notes following the tables (including the unit of analysis and decision type we invoked when working with Spaeth's databases) are particularly important.
Finally, apart from convention, certain matters are sufficiently unusual that they must be treated in an ad hoc fashion. Although we sometimes report anomalies in separate tables (see Table 4-19, for example), such peculiarities will often affect the contents of related tables. This too points to the need to pay close attention to the notes that accompany the tables.
The fact that the Court operates in a technical fashion need not cloud comprehension and understanding. We have defined terms in a nontechnical fashion, and the tables themselves do not require advanced interpretive skills. The book is based on simple numerical data, not the results of complicated statistical analyses. It should be useful to the methodologically skilled and unskilled alike.The Organization of the Book
Chapter organization progresses logically. We begin in Chapters 1 through 3 with an institutional overview of the Court's history, the constitutional and congressional provisions that govern the Court and its jurisdiction, the Court's caseload, and landmark decisions. We also identify various chronological and topical trends apparent in the Court's decisions and opinions.
Chapters 4, 5, and 6 shift the focus from cases to the individual justices. We identify family backgrounds, childhood environments, marital status, educational and employment histories, and political experiences. Dates and circumstances of nomination and confirmation are supplied as well, as are dates of Court service. The circumstances surrounding retirements, resignations, and deaths are reviewed. The justices' scholarly credentials are identified and quotations from classic opinions excerpted. The justices' voting behavior is viewed ideologically, and trends in voting agreement are presented. We also identify the justices' opinion-writing proclivities, and those who agreed between themselves.
Chapter 7 considers the political and legal environments in which the Court operates. In the first part of the chapter we identify congressional legislation most frequently the subject of Court litigation, amendments ratified to alter Court decisions, and key congressional members whose legislative activities affect the judicial system (for example, the chairs of the House and Senate judiciary committees). We map the organization of the Justice Department and list the names and dates of service of persons heading these agencies. We also chart the success of the United States as a party before the Supreme Court and note the rates of success of various administrative agencies. Finally, we enumerate the frequency with which states participate in Court litigation and the rates of success they achieve in so doing. In the second part of Chapter 7 we focus on other courts within the judicial system: federal district courts, circuit courts of appeal, specialized federal courts, and state courts. At the federal court level, we specify, among other things, the extent to which the Supreme Court has reversed and affirmed lower court decisions. For the state courts, we detail Supreme Court review of state court decisions.
Chapter 8 summarizes the public's views of the Court, both overall and by subgroup. Questions reviewed include “How knowledgeable is the public about the Court?” and “To what extent does the public support the Court's resolution of specific controversial issues?”
Chapter 9 addresses the impact of the Court on certain public policy questions. Abortion, capital punishment, school desegregation, voter registration, and reapportionment are examples of issues covered.
In compiling the data contained in the pages that follow, detailed and voluminous though they be, we have made no attempt to resolve the [Page xxvii]questions and controversies that presently surround the Court. Questions such as “Are the justices overworked, too old, too unrepresentative?” “Is the Court rendering too many liberal decisions, or too many conservative ones?” “Is the Court addressing pertinent issues of broad public concern?” “Does the solicitor general exercise too much influence over the justices?” are not answered here. The data we supply are simply that: information about the Court and its environment. We have compiled and reported these data as accurately and as objectively as possible. They do not cover the totality of the activity that occurs within the confines of the justices' “Marble Palace.” For example, we know little of what has transpired within the justices' secret conferences where they choose cases to be heard and decided and cast initial votes on the merits of the cases.1 Our data, rather, are an appropriate starting point for analysis. But by no means are they the last word on the subjects to which they pertain.Notes

The exception is the Vinson Court (1946–1953). Jan Palmer's dataset draws on the private docket books of most of the justices who sat on that Court. See The Vinson Court Era: The Supreme Court's Conference Votes (New York: AMS Press, 1990). Having gained access to these docket books, Palmer systematically presents all the votes—preliminary and final—cast by each of the justices in every case in which the Vinson Court justices voted (it excludes deadlisted cases and those in which—after discussion—no justice voted to grant certiorari). The expanded version of the Supreme Court database houses Palmer's data, as well as information of the Warren Court. See also H.W. Perry Jr., Deciding to Decide: Agenda Setting in the United States Supreme Court (Cambridge, Mass.: Harvard University Press, 1991); and Gregory A. Caldeira, John R. Wright, and Christopher J. Zorn, “Sophisticated Voting and Gate-keeping in the Supreme Court,” Journal of Law, Economics, and Organization 15 (1999): 549. Finally, we should note that Epstein, Segal, and Spaeth have now created a digital archive containing Justice Harry A. Blackmun's records pertaining to case selection (e.g., cases on the “discuss” list, the votes on certiorari, and preliminary [pool] memoranda). We hope to include summaries of these data in future editions of the Compendium.
