On August 1, David Gill, an independent candidate for U.S. House in the 13th Illinois district, filed a federal lawsuit against the Illinois requirement that independents for U.S. House need a petition of 5% of the last vote cast. The case is Gill v Scholz, c.d., 1:16cv-3221.
Gill needed 10,754 valid signatures. His petition was challenged, and the process resulted in a finding that only 8,593 of his signatures were valid. The lawsuit does not attack the accuracy of the validity check; instead it is a challenge to the 5% requirement itself.
