Service or process. Dr. Kevin Bardwell owns Northfield Urgent Care, LLC, a Minnesota medical clinic. Northfield ordered flu vaccine from Clint Pharmaceutical, a licensed distributer of flu vaccine located in Tennessee. The parties signed a credit agreement that specified that any disputes would be litigated in the Tennessee state court. When Northfield failed to pay what is owed for the vaccine, Clint Pharmaceutical field a lawsuit in Tennessee and served process on the clinic via registered mail to Dr. Bardwell, the registered agent of Northfield. Bardwells wife, who worked as a receptionist at the clinic and handled inquiries on the clinics facebook site, signed for the letter. Bardwell did not appear on trial date, however, and the Tennessee court entered a default judgment against Northfield. When Clint Pharmaceutical attempted to collect on the judgement in Minnesota, Bardwell claimed that the judgement was unenforceable. He asserted that she had not been properly served because his wife was not a registered agent. Should the Minnesota court invalidate the Tennessee judgement? Was service of process proper when it was mailed to the defendant medical clinic and the wife of the physician who owned the clinic opened the letter? Explain. [Clint Pharmaceutical v. Northfield Urgent Care, LLC, 2012 WL 3792546 ( Minn. App. 2012).]
