Belleville Catering Co. (Belleville) (plaintiff) sued Champaign Market Place, LLC (Champaign) (defendant) in federal court, alleging subject matter jurisdiction based on diversity of citizenship. Belleville’s complaint alleged that Champaign was a citizen of Delaware and Illinois as Champaign was organized under the laws of Delaware and maintained its principal place of business in Illinois. Champaign was a limited liability company (LLC) and not a corporation. Champaign’s members failed to disclose their residency. The district court accepted Belleville’s allegations and heard the case. Belleville appeals the decision in favor of Champaign.
