On July 2, some Libertarian Party candidates, and an independent candidate, filed a federal lawsuit against the Virginia law that always puts the Democratic and Republican nominees on the ballot on the top-most position. Sarvis v Judd, eastern district, 3:14cv-479. Here is a copy of the 17-page Complaint.
The case is assigned to U.S. District Court Judge Robert Payne, who has an excellent record on cases involving minor parties and independent candidates. See his dissent in Fishbeck v Hechler, 85 F.3d 162 (4th circuit, 1996). In that case, while sitting on a Circuit Court panel, he dissented when the other two judges upheld West Virginia ballot access laws in a Libertarian Party challenge to the May petition deadline for non-presidential candidates.
