A divided Ohio Supreme Court has accepted an appeal by Columbus to keep its ban on bump stocks, an accessory that allows semi-automatic weapons to fire rapidly.
Columbus banned the devices last year as part of a larger package of gun reforms. The city is challenging an appeals court ruling that allows gun rights activist Gary Witt to challenge the ban.
Columbus City Attorney Zach Klein argues that Witt hadn't been harmed by the gun law.
The Ohio Supreme Court ruled 4-3 Tuesday to accept the case.
Two gun rights groups, Ohioans for Concealed Carry and the Buckeye Firearms Foundation, were previously removed from the lawsuit after the 10th District Court of Appeals said they didn't have standing to bring a challenge.
