The Government Accountability Office drafted a report, alleging that the recently constructed federal courthouses were built larger than needed and the cost to taxpayers is $835 million since 2000. The cost of federal courthouses has been the subject of a contentious hearing before a Congressional committee. GAO also alleges the additional space requires $51 million annually to maintain. The Judicial Conference and GSA separately challenged the GAO findings. Two federal judges on behalf of the Judicial Conference criticized the GAO report, stating that the federal judiciary is working hard to utilize courthouse space efficiently based on policies that balance courtroom sharing with organized case management. The GAO and the federal judiciary have disputed over courtroom sharing policies in the past.
