"Any prosecutor filing such a complaint in a single judge county, without first having unimpeachable evidence establishing the judge had engaged in misconduct which raises substantial question as to his fitness for office, would be committing professional and political suicide," Sparks says in a response filed by his attorney, Lonnie Simmons.
"Asserting that a judge is unfit to serve in that office is an accusation that must never be made lightly or frivolously, and must be supported by solid evidence and actual knowledge of the complaint," Sparks added.
Sparks claims Thornsbury implicated him in the latest case because Sparks cooperated with federal investigators.
"I had absolutely nothing to do with this," Sparks told the Williamson Daily News, suggesting that Thornsbury is lying "to exact vengeance against me in retaliation for my cooperation with his federal investigation."
The petition argued that Sparks' license should be suspended immediately, because lawyers who hold public office are held to a higher standard of conduct and violations by elected officials are "more egregious because of the betrayal of public trust attached to the office."
"This court must insure that the public's interests are protected and that the integrity of the legal profession is maintained," it said.
It was unclear Friday when the court would rule.
