OKLAHOMA CITY (AP) — A state district judge has blocked implementation of a new law that requires top brands of wine and spirits to be sold to all Oklahoma alcohol wholesalers.

The Oklahoman reports Judge Thomas Prince in Oklahoma City ruled the new law violates the state constitution.

The Oklahoma Supreme Court had remanded the legal challenge launched to the new law by a group of liquor wholesalers. Currently, manufacturers can designate a single wholesaler to distribute their products.

The group argued the law unconstitutionally changed the amendment passed by voters in 2016 that also allows the sale of strong beer in grocery and convenience stores and the sale of cold, strong beer in liquor stores.
