Lee v. Keith, 463 F. 3d 763 (7th Cir. 2006) was a case in which, on September 18, 2006, the United States Court of Appeals for the Seventh Circuit struck down Illinois' ballot access laws, opining:
"In combination, the ballot access requirements for independent legislative candidates in Illinois--the early filing deadline, the 10% signature requirement, and the additional statutory restriction that disqualifies anyone who signs an independent candidate's nominating petition from voting in the primary--operate to unconstitutionally burden the freedom of political association guaranteed by the First and Fourteenth Amendments. Ballot access barriers this high--they are the most restrictive in the nation and have effectively eliminated independent legislative candidacies from the Illinois political scene for a quarter of a century--are not sustainable based on the state's asserted interest in deterring party splintering, factionalism, and frivolous candidacies".References
