Two state lawmakers, the Ohio State Conference of the NAACP and the Ohio Organizing Collaborative filed a lawsuit Thursday that challenges the state’s recently passed Stand Your Ground law, claiming Republican legislators violated the state constitution.

The lawsuit claims GOP lawmakers added the measure to an unrelated bill and passed it an hour later without providing public notice or debate. Everytown Law, an organization with a New York City mailing address that litigates gun safety issues, is representing the four plantiffs, along with the Ohio law firm Bloomekatz Law.
