Kentucky election law section 118.315 says that independent candidates for city office need 2 signatures, but independent candidates for other partisan local office that covers just part of a county need 20 signatures. An independent candidate for Louisville Metro Council, Deonte Hollowell, filed a petition of four signatures, and all four were valid. He was put on the ballot.
However, his Democratic opponent then sued, charging that independent candidates for that office need 20 signatures, not 2. On October 6, a state court in Jefferson County construed the law to require two signatures, not 20. See this story. The case is Clark v Hollowell, 10ci-6470. The Democratic candidate is considering whether to appeal. The independent candidate is the incumbent in his race, and he has Republican and Democratic opponents.
