Gov. Phil Bryant, about 80 lawmakers, the National Rifle Association and others have asked the Mississippi Supreme Court to let them file briefs in support of the state's open carry law.
The court had not ruled on the requests as of Monday. The motions filed by Bryant, the lawmakers and the NRA included their arguments in support of the law.
Attorney General Jim Hood asked the Supreme Court on July 22 to throw out a Hinds County judge's order that has enjoined the law, saying it was on hold until the legislature can clarify it.
Earlier this year, legislators passed and Bryant signed House Bill 2, which says adults don't need a permit to carry a gun that's not concealed. The open-carry law was supposed to go into effect July 1.
