The Maryland Supreme Court has delivered Amazon a legal victory, clearing the way for the online shopping and shipping service to operate a distribution center in Upper Marlboro over the objections of nearby residents. In a 7-0 decision, the high court said the Prince George’s County Council validly approved Amazon’s plan to use a 290,225-square-foot building in an industrial complex for a holding and distribution center for the online orders the company receives. The justices rejected the residents’ argument that Amazon’s facility qualifies as neither a permitted “warehouse” nor “distribution” center under the county’s zoning ordinance.
