At the request of the Judicial Conference Committee on Court Administration and Case Management, the Federal Judicial Center conducted a study of the use of courtrooms in the U.S. district courts. The committee requested the study in response to a November 2005 congressional subcommittee request for an empirical study of the use of federal courtrooms. The study was conducted between early 2006 and spring 2008, with data collected in twenty-six district courts during the period January 15 - July 15, 2007. For a subsequent report on bankruptcy courtroom use, see The Use of Courtrooms in U.S. Bankruptcy Courts (2010).
