Mosher v. Cook United, Inc.

After Hudson Food Warehouse (defendant), a grocery store, advertised lower prices than competitors and urged shoppers to 'check and compare,' Arthur Mosher (plaintiff) went shopping there and began writing down prices to compare against competitors; Hudson employees told him this violated store policy, and when Mosher refused to stop or to leave, he was arrested for trespassing, though the criminal charges were eventually dismissed. Mosher sued Hudson, arguing he held an irrevocable license to be in the store and was therefore not a trespasser; the trial court and court of appeals both ruled against him.
