The closely watched Costco decision, which would dismantle the three-tier system in Washington state and would also set the stage to do the same throughout the country, has now been formally appealed by Washington state’s attorney general, Rob McKenna. The Washington Liquor Control Board had earlier indicated that they would appeal, but this now makes it official. Judge Pechman, who made the ruling being appealed, has not yet decided whether to stay her ruling during the appeal process, which could easily take up to two years to wind its way through the legal system.
