A complaint was originally filed against Thompson, 58, in June by the state’s attorney general after several court employees complained about the judge's inappropriate use of the pump, which he concealed under his court robes.
Thompson was accused of using the pump on several different occasions during both civil and criminal trial proceedings and was also seen masturbating in his chambers.
Numerous witnesses of Thompson's misconduct were listed in the attorney general's complaint, including a court reporter who was terminated after she complained of seeing Thompson use the pump.
The three felony counts each come with a maximum punishment of ten years in prison and fines as high as $20,000.
Thompson made a court appearance before District Attorney Richard L. Smothermon on Jan. 20, and according to reports, he was released on his own recognizance until a preliminary hearing is held in March.
Shortly after allegations were made against Thompson, he faced a lengthy judiciary review on moral turpitude charges. Rather than face suspension from his judicial duties, Thompson opted for early retirement to avoid losing his pension, stating in a letter: "I have greatly enjoyed my public service and offer my gratitude for the public trust reposed in me during the terms I served."
Thompson had served the Oklahoma court system for nearly 22 years.
His attorney maintained throughout the ordeal that Thompson was a victim of a politically motivated set-up by attorneys who had been displeased with some of his case rulings.
