Hays County Court-at-Law Judge Millie Thompson resigned from her post Wednesday, cutting short a contentious working relationship with her court colleagues that was fraught with lawsuits and cease-and-desist orders since she took office in January. Thompson, a Democrat who ran on a platform of reform and promised a more equitable criminal justice system, turned in a resignation letter Wednesday. The Hays County Commissioners Court will appoint a new judge to the bench, according to an attorney representing the remaining judges. Thompson did not return a message seeking comment. A few weeks after Thompson took office, she barred the two other Republican judges she works with from her office via a criminal trespass warning and changed the locks to her office.
