Abstract

A technique using DEA to evaluate the administrative business of local governments exists. This paper analyzes administrative evaluations for court systems using DEA. In addition, an attempt is made to evaluate not only administrative efficiency, but also inefficiency using inverted DEA. The court system includes the Supreme Court, High Court, and District Court, etc. First, an administrative evaluation of the High Court is performed. Additionally, the District Court, Summary Court and Family Court in each prefecture of Japan is evaluated. As a result, a significant change in evaluation was not apparent for a few years since the evaluation period was short. Moreover, we have found that efficient courts had few lawsuit cases per judge, and that the opposite was true for inefficient courts. However, when there is a large number of judges and the number of lawsuits is low, the court is not efficient. In order to improve efficiency, the number of judges needs to be increased as a whole. However, there is also a need to reduce the number of judges in a portion of the court system where the number is excessive.
