Mississippi Supreme Court won't undo block on gun law JACKSON, Miss. - The Mississippi Supreme Court says it won't undo a circuit judge's order that's blocking an open-carry gun law from taking effect. Justices say they made their decision for procedural reasons, not on the merits of any arguments. Hinds County Circuit Judge Winston Kidd handed down a ruling this past Friday that blocked the gun law from taking effect on July 1. Attorney General Jim Hood filed papers with the Supreme Court on Monday, asking justices to undo Kidd's order. Hinds County District Attorney Robert Shuler Smith was among those who asked Kidd to block the law. A panel of three Supreme Court justices on Tuesday denied Hood's request. That means Kidd can hold a July 8 hearing to decide whether to extend his order.
