Gloria Sakellariadis (plaintiff) was injured in two car accidents that occurred three months apart. The first accident involved Steven Campbell (defendant), and the second accident involved Bruce Walters (defendant). Sakellariadis sued Campbell and Walters in the same lawsuit, alleging negligence. Sakellariadis alleged that she sustained injuries to the same part of her body as a result of each accident. Sakellariadis requested a jury form that required the jury to determine the allocation of responsibility for each defendant for 14 categories of damages. The trial court granted the request, and, while the jury was deliberating, Sakellariadis and Campbell settled for $150,000. The jury awarded damages of $518,000 to Sakellariadis and allocated 50 percent responsibility to each of Campbell and Walters. The trial court then entered judgment against Walters for 50 percent of the damages. Sakellariadis appealed, arguing that Walters should be responsible for the full amount of damages, less the amount paid by Campbell, on a theory of joint and several liability.
