Donald D. Thompson had been convicted on four counts of indecent exposure and sentenced to four years in prison for using a penis pump underneath his robe during court hearings. He served 20 months and was suspended from law practice.
Thompson was receiving $7,789 a month when his benefits were cut off on grounds that his conduct violated his oath of office.
The "decision was made in haste and a result of conjuncture and innuendo and not supported by evidence," he said in a motion filed challenging the decision by the Oklahoma Public Employees Retirement System.
Thompson is asking Oklahoma County District Judge Patricia Parrish to reinstate either all or much of his judicial retirement benefits.
Thompson had spent almost 23 years on the bench and had served as a state legislator before retiring from the court in 2004.
Thompson testified that the penis pump was given to him as a joke by a longtime buddy.
"It wasn't something I was hiding," he said.
Thompson said he may have squeezed the pump's handle during court cases but never used it to masturbate.
A court employee told police that she saw Thompson use the device almost daily during the August 2003 murder trial of a man accused of shaking a toddler to death. A whooshing sound could be heard on an audiotape of the trial.
Police built a case against the judge after an officer testifying in a 2003 murder trial saw a piece of plastic tubing disappear under Thompson's robe. During a break, officers took photographs of the penis pump under the desk.
Detectives later found semen after checking the carpet, Thompson's robes and his chair behind the bench, according to court records.
