A U.S. District Court in Arkansas has set a hearing in the week of July 27, 2015, for the independent candidate petition deadline lawsuit, Moore v Martin, 4:14cv-65. The 2013 legislature moved the deadline from May to March, even though a similar Arkansas deadline had been held unconstitutional three times in the past.
Other pending constitutional lawsuits against early deadlines are in Alabama, Arizona, Illinois, and Nevada.
