According to the Maryville Daily Times [1], the Tennessee Court of the Judiciary is looking in to questions about recordkeeping, the disposition of cases and issues related to local court rules. The questions were raised by Judge Mike Meares after another judge wrote a letter to the editor with confusing information about the disposition and assignment of cases.
The scope of the investigation is not clear from the article. It says there is "apparently" an investigation, and some witnesses were "reportedly" questioned, and that there "appears" to be a dispute regarding court administration.
