Different types of cases impose different work demands on judges. Case weights are a measure of the average time consumed by cases of one type relative to other types. In 2003-2004, the Federal Judicial Center conducted a study to update existing weights for federal district courts using an event-based method. This method, which was new to the federal courts, combined information on the type and frequency of case events with information on the time judges require to complete these events. The Judicial Conference Committee on Judicial Resources and its Subcommittee on Judicial Statistics, which requested the study, approved the new set of weights in June 2004.
