SALT LAKE CITY — A group of Utah bar and restaurant owners have filed a lawsuit against Gov. Gary Herbert and Richard Saunders, the interim executive director of the Utah Department of Health, over the state's 10 p.m. curfew on alcohol sales. In a complaint for declaratory and injunctive relief filed Thursday in Utah's 3rd District Court, the plaintiffs say the curfew is "an unreasonable restriction on the business operations" of the businesses "causing irreparable and distinct harms to the Plaintiffs' bar and restaurant establishments and employees, without evidence or justification from the Governor or Utah Department of Health that this restriction is necessary or narrowly tailored to prevent the spread" of COVID-19.
