Former Livingston County district court judge Theresa Brennan has pleaded guilty to perjury.
The maximum penalty is 15 years.
Two other lesser charges against Brennan – misconduct in office and tampering with evidence – were dropped.
Brennan was removed from office by the Michigan Supreme Court earlier this year for numerous offenses.
Hearings by the Michigan Judicial Tenure Commission found that Brennan failed to disclose close personal relationships with people involved in cases before her, ordered staff to perform personal work for her on court time, verbally abused attorneys and others appearing in her courtroom, refused to remove herself as the judge overseeing her own divorce case, destroyed evidence on her cell phone related to her divorce case, and lied to investigators to conceal her offenses.
“This defendant violated the very tenets we as a society hold dear: truth, honor and justice,” Attorney General Dana Nessel said in a statement. “She made a mockery of her oath of office and undermined the integrity of the bench." Brennan is scheduled to be sentenced on January 17.
