Lower Federal Court Confirmation Database, 1977-2004

(compiled by Wendy L. Martinek; archived at the Center on Democratic Performance at Binghamton University)

The Lower Federal Confirmation Database contains information on nominations to Article III district and circuit courts from the beginning of 1977 through the end of December, 2004. The original database was created at the behest of the Constitution Project's Courts Initiative (formerly Citizens for Independent Courts) by Wendy L. Martinek, Binghamton University. This is the most recent update to that original database. Based on the feedback provided by users of the original database, the database has been split into two files: one containing the data related to senatorial processing of nominations, and one containing the data related to presidential processing of nominations. All documentation is provided in Adobe pdf format.

U.S. Supreme Court Amicus Curiae Database, 1946-2001

(compiled by Paul Collins; archived at the University of North Texas)

The U.S. Supreme Court Amicus Curiae Database, 1946-2001 contains data on amicus curiae briefs filed in the U.S. Supreme Court's orally argued cases from 1946-2001. This database contains a wealth of information on amicus curiae participation in the U.S. Supreme Court, including the number of amicus briefs filed for the petitioner, respondent, and those failing to identify their preferred disposition; the number of amicus briefs advocating for the liberal and conservative positions; as well as data on the amicus curiae activity on the U.S. Solicitor General. The data are in Stata 10.0 format, compressed in a ZIP file. The data folder also contains the data and do files necessary to replicate the statistical analyses published in Friends of the Supreme Court: Interest Groups and Judicial Decision Making (Collins 2008). The data on amicus curiae briefs filed from 1946-1995 were collected primarily by Kearney and Merrill (2000). The data on amicus curiae briefs from 1995-2001, in addition to those cases missing from the Kearney and Merrill (2000) database, were collected by Collins.
