Courtney McBride (plaintiff) developed a rare skin disease after receiving treatment at a county hospital. McBride filed suit in federal district court in Alabama against the treating physician, Dinesh Karumanchi, M.D.; Houston County Health Care Authority (Houston County); and others (defendants). McBride alleged various claims, including medical malpractice, and asserted that the district court had diversity-of-citizenship jurisdiction under 28 U.S.C. § 1332, as well as federal-question jurisdiction under 28 U.S.C. § 1331 and supplemental jurisdiction under 28 U.S.C. § 1367. The district court granted several of the defendants’ motions for summary judgment and also dismissed Houston County from the action, leaving Dr. Karumanchi as the remaining defendant. Dr. Karumanchi claimed that the district court lacked diversity-of-citizenship jurisdiction to continue the matter to trial because McBride lived in Alabama at the time of filing suit. However, McBride claimed that she lived in Florida at the time. After considering the parties’ briefs on jurisdiction, the district court conducted a hearing on the matter.
