Democrat Nima Kulkarni's primary opponent, William Zeitz, has filed a lawsuit against her and Kentucky Secretary of State Michael Adams.
Justices said Nima Kulkarni did not follow the law, but her legal team believes there's hope for her to stay in office.
The high court's ruling upholds the State Court of Appeals' May 15 decision to disqualify her because she did not comply with a state law.
The political fate of incumbent state Rep. Nima Kulkarni is in the balance, after she was disqualified from competing in the May Democratic primary.
The high court ordered the Jefferson County Board of Elections and state Secretary of State not to certify the election until the issue of Kulkarni's eligibility is reviewed by the justices.
One of the two required witnesses who are Democratic voters in the 40th District necessary to sign for Kulkarni’s reelection was a registered Republican, according to the court of appeals three-judge panel.
A judge denied Dennis Horlander's complaint about Nima Kulkarni.
Wednesday, Rep. Nima Kulkarni sat in court as the defendant, not a lawyer, over a complaint challenging her paperwork to run for reelection.
