AIDS-Related Written Court Decisions in Federal and State Courts, 1984-1989: [United States] (ICPSR 6502)

Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1984-01-01--1989-01-01
This data collection was designed to identify the party characteristics, case attributes, and idea structures of written court decisions related to Auto-Immune Deficiency Syndrome (AIDS). Written court decisions related to AIDS in state and federal courts were located via the LEXUS and WESTLAW data systems. For a case to be eligible, it had to address an issue involving AIDS or involve a party who was believed to be infected with Human Immunodeficiency Virus (HIV), and a legal decision had to provide sufficient written material to analyze. Coding was completed by three individuals with legal training based on a team-developed codebook. Except in those areas where a preliminary test showed 90-percent reliability, variables were coded based on a consensus rule. Variables include court jurisdiction, whether the case was civil or criminal, case issue area, gender of plaintiff, relationship between parties, demand and primary purpose of the demand by the defendant and the plaintiff, what the court explicitly relied upon for its decision, whether the plaintiff or defendant had AIDS, AIDS-Related Complex (ARC), or was HIV-infected, and whether the plaintiff or defendant was gay, an IV drug user, a prisoner or an accused criminal, a member of a stigmatized group, or a racial or an ethnic minority. The unit of analysis is the written court decision.

The Anatomy of Discretion: An Analysis of Prosecutorial Decision-making for Cases Processed by Offices in One Northern County and One Southern County, 2007-2010 (ICPSR 32542)

Released/updated on: 2016-04-21
Geographic coverage: United States
Time period: 2009-01-01--2011-06-01, 2007-01-01--2009-07-01, 2010-10-01--2011-03-01

Prosecuting attorneys enjoy broad discretion in making decisions that influence criminal case outcomes. This study examines the impact of legal, quasi-legal, and extra-legal factors on case outcomes throughout the prosecutorial process. It then examines how prosecutors weigh these factors in their decision making and explores the formal and informal mechanisms that constrain or regulate prosecutors' decision-making.

The study examines case screening decisions, charging decisions, plea offers, sentence recommendations, and dismissals in two moderately large county prosecutors' offices. It includes statistical analyses of actual case outcomes, responses to a standardized set of hypothetical cases, and responses to a survey of prosecutors' opinions and priorities, as well as qualitative analyses of two waves of individual interviews and focus groups. It addresses the following questions:

  1. How did prosecutors define and apply the concepts of justice and fairness?
  2. What factors were associated with prosecutorial outcomes at each stage?
  3. How did prosecutors interpret and weigh different case-specific factors in making decisions at each stage?
  4. How did contextual factors constrain or regulate prosecutorial decision making?
  5. How consistent were prosecutors' decisions across similar cases? What case-level and contextual factors influenced the degree of consistency?

Assessing Local Legal Culture: Practitioner Norms in Four Criminal Courts, 1979 (ICPSR 7808)

Released/updated on: 2005-11-04
Geographic coverage: United States
This study attempts to operationalize the concept of local legal culture by examining differences in the processing of twelve hypothetical criminal cases in four criminal courts. Questionnaires asking how these hypothetical cases should best be handled were administered to judges, district attorneys, and defense attorneys in four cities: Bronx County (New York City), New York, Detroit, Michigan, Miami, Florida, and Pittsburgh, Pennsylvania. In each city, the presiding judge, prosecutor, and head of the public defender's office were informed of the project. Questionnaires were distributed to prosecuting attorneys and public defenders by their supervisors. Judges were contacted in person or given questionnaires with a cover letter from the presiding judge. All questionnaires were completed anonymously and returned separately by respondents. The variables include number of years the respondent had been in the criminal justice system, preferred mode of disposition and of sentencing for each of the twelve cases, and the respondents' predictions of the probability of conviction in each case.

Assessment of Defense and Prosecutorial Strategies in Terrorism Trials in the United States, 1980-2004 (ICPSR 26241)

Released/updated on: 2014-11-11
Geographic coverage: United States
Time period: 1980-01-01--2004-01-01
This study created a flat-file database of information regarding defendants who were referred to United States Attorneys by the Federal Bureau of Investigation (FBI) following official terrorism investigations between 1980 and 2004. Its ultimate goal was to provide state and federal prosecutors with empirical information that could assist federal and state prosecutors with more effective strategies for prosecution of terrorism cases. The results of this study enhanced the existing 78 variables in the AMERICAN TERRORISM STUDY, 1980-2002 (ICPSR 4639) database by adding the 162 variables from the Prosecution and Defense Strategies (PADS) database. The variables in the PADS database track information regarding important pleadings, motions, and other key events that occur in federal terrorism trials; the PADS variables measure the strategies used by legal counsel as well as other legal nuances.

This project sought to study the District Attorney of New York's (DANY) current practices by addressing the complex relationship between prosecutorial decision making and racial and ethnic justice in felony and misdemeanor cases closed in New York County in 2010-2011. Using a mixed-methods approach, administrative records from the DANY case-management systems and prosecutorial interviews were examined to study case acceptance for prosecution, pretrial detention and bail determination, case dismissal, plea offers, and sentencing. Researchers developed five hypotheses for the data collected:

  1. Blacks and Latinos are more likely to have their cases accepted for prosecution than similarly situated white defendants.
  2. Blacks and Latinos are more likely to be held in pretrial detention and less likely to be released on bail.
  3. Blacks and Latinos are less likely to have cases dismissed.
  4. Blacks and Latinos are less likely to receive a plea offer to a lesser charge and more likely to receive custodial sentence offers.
  5. Blacks and Latinos are more likely to be sentenced to custodial punishments.

All criminal activity of the defendant was examined, as well as their demographics and prior history, the location of the crime. Information on the Assistant District Attorney (ADA) was examined as well, including their demographics and caseload in order to more thoroughly understand the catalysts and trends in decision making.

Released/updated on: 1992-02-16
Geographic coverage: United States
The purpose of this study was to provide a current listing of all felony courts in this country and to provide a universe from which a sample of courts could be selected based on felony caseload. The study includes information on all state felony courts in the United States, including the number of cases filed and disposed by conviction, acquittal, dismissal, or other means. Court administrators were asked to indicate the manner in which cases filed and disposed were counted, such as by defendant, charge, or indictment information. The total number of cases disposed during the period was also collected for juvenile delinquents and for traffic offenses (moving violations) where applicable. Finally, data were gathered on whether felonies reduced to misdemeanors were included in the felony count and whether lower courts in the jurisdiction accepted guilty pleas to felonies.

Civil Justice Survey of State Courts, 2005 (ICPSR 23862)

Released/updated on: 2011-11-02
Geographic coverage: United States
The Civil Justice Survey of State Courts (CJSSC), 2005 is a systematic examination of general civil (that is, tort, contract, and real property) cases disposed of by bench or jury trial in a national sample of state courts of general jurisdiction in 2005. This study expands on the 1992, 1996, and 2001 CJSSC by collecting a nationally representative sample of bench and jury trials concluded in 156 urban, suburban, and rural counties. Prior iterations of the CJSSC focused on general civil cases concluded by bench or jury trial in a sample of the nation's 75 most populous counties. The 2005 CJSSC was designed and carried out by the National Center for State Courts. Westat designed the national sampling framework for this survey. The data collection produced two datasets. The first contains information on general civil (tort, contract, and real property) cases disposed of by bench or jury trial in a national sample of counties in 2005. Detailed case level information was obtained on these trials, including types of civil cases litigated at trial, characteristics of litigants involved in trials, who wins in trials, compensatory award amounts, punitive damages, case processing times, and post-trial litigation. The other data file contains aggregate information on the number of general civil trial and nontrial dispositions that occurred in 2005 in CJSCC counties that had the capacity to provide these data. This is the fourth in a series of data collections begun in 1992 [CIVIL JUSTICE SURVEY OF STATE COURTS, 1992 (ICPSR 6587), CIVIL JUSTICE SURVEY OF STATE COURTS, 1996 (ICPSR 2883), and CIVIL JUSTICE SURVEY OF STATE COURTS, 2001 (ICPSR 3957)].

Community Context and Sentencing Decisions in 39 Counties in the United States, 1998 (ICPSR 3923)

Released/updated on: 2005-11-04
Geographic coverage: United States
This study aimed to understand the extent to which punishment is influenced by the larger social context in which it occurs by examining both the main and conditioning influence of community context on individual sentences. The primary research questions for this study were (1) Does community context affect sentencing outcomes for criminal defendants net of the influence of defendant and case characteristics? and (2) Does community context condition the influences of defendant age, race, and sex on sentencing outcomes? Data from the 1998 State Court Processing Statistics (SCPS) were merged with a unique county-level dataset that provided information on the characteristics of the counties in which defendants were adjudicated. County-level data included unemployment, crime rates, sex ratio, age structure, religious group affiliation, and political orientation.

Cuyahoga County, Ohio, Heroin and Crime Initiative: Informing the Investigation and Prosecution of Heroin-Related Overdose, 2012-2021 (ICPSR 38295)

Released/updated on: 2023-09-27
Geographic coverage: United States, Ohio
Time period: 2012-01-01--2020-01-01, 2014-01-01--2019-01-01, 2018-04-01--2021-09-30

In 2013, the Cuyahoga County (Ohio) Medical Examiner's Office (CCMEO) and the Regional Forensic Science Laboratory developed the Heroin Involved Death Investigation (HIDI) alert system and protocol in response to a substantial increase in opioid-related overdose fatalities. The HIDI protocol is designed to support a safe, coordinated, and rapid response to an active, suspected opioid-overdose death scene, or suspected opioid-overdose deaths occurring at hospitals that are not considered active scenes, by alerting investigators to potential dangers and facilitating the timely protection of scene integrity and evidence collection in order to successfully investigate and prosecute drug traffickers.

The primary goals of the project were to:

  1. Complete extended coding of local medical examiner decedent data--investigative reports and toxicology to identify demographic or geographic trends or patterns of overdose deaths, as well as paraphernalia and evidence present at death scenes that may be useful to prosecutions;
  2. Examine the efficiency of how cases flow through the investigative and prosecutorial stages and how these could be improved;
  3. Identify key variables that may contribute to the successful indictment of traffickers connected to fatal and non-fatal overdose cases; and
  4. Evaluate the implementation and perceived effectiveness of the Cuyahoga County HIDI protocol.

This multi-method project involved three phases of data collection and analysis. First, a forensic epidemiologist coded and analyzed existing CCMEO records for decedent toxicology and death scene characteristics, focusing on drug-related fatalities. Second, county and federal cases prosecuted for drug trafficking, especially those linked to deaths, were systematically reviewed to determine what evidence was deemed important for successful indictment. Third, interviews and focus groups were conducted with key stakeholders from local and federal law enforcement, intelligence analysts, public health officials, and local and federal prosecutors to learn about the HIDI protocol.

Data and documentation for interviews and focus groups will be made available in a future update.

Effects of Cognitive Interviewing, Practice, and Interview Style on Children's Recall Performance in California, 1989-1990 (ICPSR 9789)

Released/updated on: 2005-11-04
Geographic coverage: United States, California
Time period: 1989-01-01--1990-01-01
This data collection, designed to improve the quality of children's testimony in court, evaluates how different types of interview formats affect the completeness and accuracy of children's recall performance. Specifically, the study assesses the impact of a "practice interview" about an event on the completeness and accuracy of later reports about a second, unrelated event. Three interview conditions were employed, and each condition consisted of both a practice interview and a target interview. The three conditions were RS, RC, and CC, where "R" represents a practice session with rapport-building only, "S" represents a target interview that contained all components of the standard interview procedure, and "C" represents either a practice or target interview that contained all components of the cognitive interview procedure. In rapport-building sessions, interviewers talked about school activities, family life, and favorite games with the child. In standard and cognitive interview sessions, the rapport-building sessions were followed by a request from the interviewer for the child to verbalize a narrative account of "what happened" during an event that had been previously staged by the experimenter. This narrative account was then followed by the interviewer's request for additional information about the event. Cognitive interviews also included several additional questions that were hypothesized to improve recall performance. The number of correct items recalled and the number of incorrect items generated were used to compare the performance of children in the three interview conditions.

Estimating the Prevalence of Wrongful Convictions, Virginia, 1973-1987 (ICPSR 36836)

Released/updated on: 2021-09-15
Geographic coverage: United States, Virginia
Time period: 1973-01-01--1987-01-01
This study extends research on wrongful convictions in the United States and the factors associated with justice system errors that lead to the incarceration of innocent people. Among cases where physical evidence produced a DNA profile of known origin, 12.6 percent of the cases had DNA evidence that would support a claim of wrongful conviction. Extrapolating to all cases in our dataset, the investigators estimate a slightly smaller rate of 11.6 percent. This result was based on forensics, case processing, and disposition data collected on murder and sexual assault convictions in the 1970s and 1980s across 56 circuit courts in the state of Virginia. To address limitations in the amount and type of information provided in forensic files that were reviewed in the Urban Institute's prior examination of these data, the current research includes data collected through a review of all publicly available documents on court processes and dispositions across the 714 convictions, which the investigators use to reassess prior estimates of wrongful conviction.

Evaluating the Impact of a Specialized Domestic Violence Police Unit in Charlotte, North Carolina, 2003-2005 (ICPSR 20461)

Released/updated on: 2008-07-01
Geographic coverage: North Carolina, Charlotte, United States
Time period: 2003-01-01--2005-01-01
The specific goals of this project were (1) to assess the selection criteria used to determine the domestic violence cases for intensive intervention: what criteria are used, and what differentiates how cases are handled, (2) to track the outcomes through Charlotte-Mecklenburg Police Department (CMPD), Mecklenburg domestic violence court, and the Mecklenburg jail for the different methods of dealing with the cases, and (3) to provide an assessment of the relative effectiveness of a specialized domestic violence unit vis-a-vis normal patrol unit responses in terms of repeat calls, court processing, victim harm, and repeat arrests. The population from which the sample was selected consisted of all police complaint numbers for cases involving domestic violence (DV) in 2003. The unit of analysis was therefore the domestic violence incident. Cases were selected using a randomized stratified sample (stratifying by month) that also triple-sampled DV Unit cases, which generated 255 DV Unit cases for inclusion. The final sample therefore consists of 891 domestic violence cases, each involving one victim and one suspect. Within this final sample of cases, 25 percent were processed by the DV Unit. The data file contains data from multiple sources. Included from the police department's computerized database (KBCOPS) are variables pertaining to the nature of the crime, victim information and suspect information such as suspect and victim demographic data, victim/offender relationship, highest offense category, weapon usage, victim injury, and case disposition status. From police narratives come such variables as victim/offender relationship, weapon use (more refined than what is included in KBCOPS data), victim injury (also a more refined measure), and evidence collected. Variables from tracking data include information regarding the nature of the offense, the level/type of harm inflicted, and if the assault involved the same victim in the sample. Variables such as amount of jail time a suspect may have had, information pertaining to the court charges (as opposed to the charges at arrest) and case disposition status are included from court and jail data.

Released/updated on: 2020-06-29
Geographic coverage: United States, Missouri, St. Louis
Time period: 2015-07-01--2018-06-30
This study examines the entire range of case-processing decisions after arrest, from charging to sentencing of firearm-related crimes. This study analyzes the cumulative effects of each decision point, after a charge has been issued, on the subsequent decisions of criminal justice officials. It examines criminal justice decisions regarding a serious category of crime, gun-related offenses. These offenses, most of which are felonious firearm possession or firearm use cases, vary substantially with respect to bail, pretrial detention, and sentencing outcomes (Williams and Rosenfeld, 2016). The focus of this study is St. Louis, where firearm violence is a critical public problem and where neighborhoods range widely in both stability and level of disadvantage. These communities are characterized on the basis of a large number of demographic and socioeconomic indicators. The study aims to enhance understanding of the community context of the criminal justice processing of firearm-related crimes.

The Judicial Oversight Demonstration (JOD) was designed to test the feasibility and impact of a coordinated response to intimate partner violence (IPV) that involved the courts and justice agencies in a central role. The primary goals were to protect victim safety, hold offenders accountable, and reduce repeat offending. The two primary evaluation objectives were: (1) to test the impact of JOD interventions on victim safety, offender accountability, and recidivism, and (2) to learn from the experiences of well-qualified sites who were given resources and challenged to build a collaboration between the courts and community agencies to respond to intimate partner violence. Dorchester, Massachusetts, and Washtenaw County, Michigan, participated in a quasi-experimental evaluation of the impact of the program. IPV cases reaching disposition during the JOD were compared to similar cases reaching disposition in Lowell, Massachusetts, and Ingham County, Michigan. All IPV cases reaching disposition from approximately January 2003 to November 2004 (see Study Time Periods and Time Frames) were reviewed and included in the sample if appropriate. To be eligible for the sample, cases had to involve: (1) criminal IPV charges; (2) victims and offenders age 18 or older; and (3) victims and offenders who lived in the target jurisdiction at the time of case disposition. Cases that reached disposition more than a year after the incident were excluded to limit loss of data due to poor recall of the facts of the incident and police response. The evaluation design of JOD in Milwaukee differed from that of the other two sites. The evaluation in Milwaukee was based on a quasi-experimental comparison of offenders convicted of IPV and ordered to probation during JOD (January 1, 2001, to May 21, 2002) and before JOD (October 8, 1997, to December 21, 1999). This design was selected when early plans for an experimental design had to be abandoned and no comparable contemporaneous comparison group could be identified. Data for this evaluation were collected from court and prosecutors' records of case and defendant characteristics, probation files on offender supervision practices, and official records of rearrest, but do not include interviews with victims or offenders. This data collection has 20 data files containing 3,578 cases and 4,092 variables. The data files contain information related to each site's Batterer Intervention Programs (Parts 1, 8, and 15), court data (Parts 2, 12, 13, 14, 16, and 18), law enforcement (Parts 3, 11, and 17), and victim data (Parts 4, 5, 6, 9, 10, and 19). The Dorchester, Massachusetts, and Washtenaw County, Michigan, Impact Evaluation Data (Part 7) include baseline and follow-up information for the offender and the victim. The data file also contains Probation Supervision Performance Reports, Victim Services Logs, and Case Incident Fact Sheet information. The Milwaukee, Wisconsin, Impact Evaluation Data (Part 20) include information related to the offender and the victim such as age, race, and sex, as well as arrest records including charges filed.

Evaluation of No-Drop Policies for Domestic Violence Cases in San Diego, California, Omaha, Nebraska, Klamath Falls, Oregon, and Everett, Washington, 1996-2000 (ICPSR 3319)

Released/updated on: 2006-03-30
Geographic coverage: Oregon, Omaha, Klameth Falls, San Diego, United States, Everett, California, Washington, Nebraska
Time period: 1996-01-01--2000-01-01
This study sought to examine the effects of no-drop policies on court outcomes, victim satisfaction with the justice system, and feelings of safety. Moreover, researchers wanted to determine whether (1) prosecution without the victim's cooperation was feasible with appropriate increases in resources, (2) implementing a no-drop policy resulted in increased convictions and fewer dismissals, (3) the number of trials would increase in jurisdictions where no-drop was adopted as a result of the prosecutor's demand for a plea in cases in which victims were uncooperative or unavailable, and (4) prosecutors would have to downgrade sentence demands to persuade defense attorneys to negotiate pleas in the new context of a no-drop policy. Statutes implemented in San Diego, California, were designed to make it easier to admit certain types of evidence and thereby to increase the prosecutor's chances of succeeding in trials without victim cooperation. To assess the impact of these statutes, researchers collected official records data on a sample of domestic violence cases in which disposition occurred between 1996 and 2000 and resulted in no trial (Part 1), and cases in which disposition occurred between 1996 and 1999, and resulted in a trial (Part 2). In Everett, Washington (Part 3), Klamath Falls, Oregon (Part 4), and Omaha, Nebraska (Part 5), researchers collected data on all domestic violence cases in which disposition occurred between 1996 and 1999 and resulted in a trial. Researchers also conducted telephone interviews in the four sites with domestic violence victims whose cases resolved under the no-drop policy (Part 6) in the four sites. Variables for Part 1 include defendant's gender, court outcome, whether the defendant was sentenced to probation, jail, or counseling, and whether the counseling was for batterer, drug, or anger management. Criminal history, other domestic violence charges, and the relationship between the victim and defendant are also included. Variables for Part 2 include length of trial and outcome, witnesses for the prosecution, defendant's statements to the police, whether there were photos of the victim's injury, the scene, or the weapon, and whether medical experts testified. Criminal history and whether the defendant underwent psychological evaluation or counseling are also included. Variables for Parts 3-5 include the gender of the victim and defendant, relationship between victim and defendant, top charges and outcomes, whether the victim had to be subpoenaed, types of witnesses, if there was medical evidence, type of weapon used, if any, whether the defendant confessed, any indications that the prosecutor talked to the victim, if the victim was in court on the disposition date, the defendant's sentence, and whether the sentence included electronic surveillance, public service, substance abuse counseling, or other general counseling. Variables for Part 6 include relationship between victim and defendant, whether the victim wanted the defendant to be arrested, whether the defendant received treatment for alcohol, drugs, or domestic violence, if the court ordered the defendant to stay away from the victim, and if the victim spoke to anyone in the court system, such as the prosecutor, detective, victim advocate, defense attorney, judge, or a probation officer. The victim's satisfaction with the police, judge, prosecutor, and the justice system, and whether the defendant had continued to threaten, damage property, or abuse the victim verbally or physically are also included. Demographic variables on the victim include race, income, and level of education.

Users should refer to the accompany readme file for a brief description of the files available with this collections and consult the investigator(s) if further information is needed.

The study examined four research questions: (1) Was the Red Hook Community Justice Center (RHCJC) implemented according to plan?; (2) Did RHCJC make a difference in sanctioning, recidivism, and arrests?; (3) How did RHCJC produce any observed reductions to recidivism and arrests?; and (4) Is RHCJC cost-efficient from the viewpoint of taxpayers?

The community survey (Red Hook Resident Data, n = 95) was administered by research teams in the spring and summer of 2010. Teams generally went house-to-house ringing apartment buzzers at varying times of day, usually on the weekend when working people are more likely to be home or approached people on the sitting on park benches to conduct interviews.

In autumn 2010, the research team administered a survey to 200 misdemeanor offenders (Red Hook Offender Data, n = 205) who were recruited from within the catchment area of the Red Hook Community Justice Center (RHCJC) using Respondent Driven Sampling (RDS).

To examine how the RHCJC was implemented (Red Hook Process Evaluation Data, n= 35,465 and Red Hook Work File Data, n= 3,127), the research team relied on a diverse range of data sources, including 52 structured group and individual interviews with court staff and stakeholders carried out over five site visits; observation of courtroom activities and staff meetings; extensive document review; and analysis of case-level data including all adult criminal cases and some juvenile delinquency cases processed at the Justice Center from 2000 through 2009.

To aid in understanding the RHCJC's impact on the overall level of crime in the catchment area, researchers obtained monthly counts (Arrest Data, n = 144) of felony and misdemeanor arrests in each of the three catchment area police precincts (the 72nd, 76th, and 78th precincts).

This study utilized data from the Bureau of Justice Statistics on federal criminal case processing to study jurisdictional variations in prosecutorial decision-making outcomes. It linked information across multiple federal agencies in order to track individual offenders across the various stages of the federal justice system. Specifically, it combined arrest information from the United States Marshall's Service with charging information from the Executive and Administrative Offices of the United States Attorney and with sentencing information from the United States Sentencing Commission. These individual data were subsequently augmented with additional information on federal courts to examine contextual variations in charging decisions across federal jurisdictions.

There are three data files. Dataset 1 (Executive Office for United States Attorneys (EOUSA) and United States Marshals Service (USMS) Data) contains 88 variables and 284,869 cases. Dataset 2 (Administrative Office of the United States Courts (AOUSC) and United States Sentencing Commission (USSC) Data) contains 717 variables and 256,598 cases. Dataset 3 (United States District Court Characteristics Data) contains 6 variables and 89 cases.

Only Dataset 3 is being released as part of the available study materials. Datasets 1 and 2 can be re-created using the syntax files which are included in the study materials.

Expanded United States Supreme Court Judicial Database, 1946-1968 Terms (ICPSR 6557)

Released/updated on: 2005-11-04
Geographic coverage: United States
Time period: 1946-01-01--1968-01-01
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.

The purpose of the study was to compare how the quantity versus the quality of evidence influences the likelihood of trial convictions and plea decisions and examine whether evidence has differential impacts on the perceived likelihood of trial convictions and plea values. In Phase I (Phase I Data, n=2,593) defense attorneys, prosecutors, and judges, representing all 50 states and the District of Columbia, completed an online survey of a hypothetical legal case in which the presence of three types of evidence (confession, eyewitness, and DNA) and length of defendant criminal history were manipulated. In Phase II (Phase II Data, n=502), researchers worked with two District Attorneys' offices in New York state to code the contents of case files. Researchers coded 502 closed cases from 2005 and 2006, all of which originated as felony arrests. Researchers also obtained criminal history record information on the defendants involved in the cases.
