A federal appeals court has reinstated a 76-year-old old ban on grocery stores, gas stations and other retailers selling wine and liquor in Kentucky after finding the law doesn't violate the equal protection clause of the U.S. Constitution.The U.S. 6th Circuit Court of Appeals on Wednesday reversed a decision by U.S. District Judge John G. Heyburn in 2012 to lift the restriction.Judge Deborah L. Cook wrote for the court that the state "indisputably maintains a legitimate interest" in reducing access to high-alcohol content products.A Louisville convenience store, Maxwell's Pic-Pac, and the Food with Wine Coalition challenged the ban in a lawsuit filed in federal court in 2011. The plaintiffs said the law treats groceries and other retailers differently from package liquor stores simply because they sell food and other staples.
