Expanded United States Supreme Court Judicial Database, 1946-1968 Terms (ICPSR 6557)
Principal Investigator(s): Spaeth, Harold J.
This data collection is an expanded version of UNITED STATES SUPREME COURT JUDICIAL DATABASE, 1953-1996 TERMS (ICPSR 9422), encompassing all aspects of United States Supreme Court decision-making from the beginning of the Vinson Court in 1946 to the end of the Warren Court in 1968. Two major differences distinguish the expanded version of the database from the original collection: the addition of data on the decisions of the Vinson Court, and the inclusion of the conference votes of the Vinson and Warren courts. Whereas the original collection contained only the vote as reported in the UNITED STATES SUPREME COURT REPORTS, the expanded database includes all votes cast in conference. Concomitant with the expansion of the database is a shift in its basic unit of analysis. The original collection contained every case in which at least one justice wrote an opinion, and cases without opinions were excluded. This version includes every case in which the Court cast a conference vote, with and without opinions. The justices cast many more votes than they wrote opinions, and hence, the number of Warren Court records in this version increased by more than a factor of two over the original version. As in the original collection, distinct aspects of the Court's decisions are covered by six types of variables: (1) identification variables including case citation, docket number, unit of analysis, and number of records per unit of analysis, (2) background variables offering information on origin of case, source of case, reason for granting cert, parties to the case, direction of the lower court's decision, and manner in which the Court takes jurisdiction, (3) chronological variables covering date of term of court, chief justice, and natural court, (4) substantive variables including multiple legal provisions, authority for decision, issue, issue areas, and direction of decision, (5) outcome variables supplying information on form of decision, disposition of case, winning party, declaration of unconstitutionality, and multiple memorandum decisions, and (6) voting and opinion variables pertaining to the vote in the case and to the direction of the individual justices' votes.
