On November 21, the Ohio Libertarian Party filed this reply brief in Libertarian Party of Ohio v Husted, s.d., 2:13cv-953. The issue in the lawsuit at this point is whether SB 193, passed in late 2013, which rewrote the definition of “political party”, is constitutional.
One of the Libertarian Party’s contentions is that the 2013 law violates the Ohio Constitution, which seems to say that all parties must nominate by primary. The federal court can only involve itself in this issue if the federal court rules that the state waived its Eleventh Amendment immunity. That is why so much of this brief concerns the Eleventh Amendment. Thanks to Steve Linnabary for the link.
