On March 23, the Ohio Libertarian Party, which is intervening in the lawsuit State ex rel Democratic Party v LaRose, 2020-388, filed this brief in the Ohio Supreme Court. The brief argues that it was unlawful for Secretary of State Frank LaRose to stop the March 17 primary from going forward. He took that action on March 16.
The Ohio Libertarian Party is ballot-qualified and the law requires it to nominate by primary. UPDATE: Here is the Ohio Democratic Party’s brief.
