On May 1, the Ohio Libertarian Party asked the U.S. Supreme Court to put its statewide candidates on the primary ballot. Here is the 28-page request. The document appears to be longer than 28 pages because it has the court decisions from the lower courts attached.
One of the many points the brief raises is that if it is really important for Ohio to enforce the law that requires all circulators to show their employers on each sheet, the Secretary of State would enforce it. In this case, he did not enforce it and put the Libertarians on the primary ballot. But when a private individual filed a challenge, then it was enforced.
In the U.S. Supreme Court, the case is no. 13A1089. Here is a news story about the filing.
