In a joint and several liability Mississippi civil action action based on fault, including a medical malpractice action, each tortfeasor or wrongdoer is liable only for damages allocated to them in direct proportion to their percentage of fault. Miss. Code Ann. § 85-5-7 (Westlaw 2007). Fault must be assigned to absent tortfeasors who contributed to the injury (such as persons who have settled or were not sued) and those with immunity. Id.; Blailock v. Hubbs, 919 So. 2d 126 (Miss. 2005).  This rule does not apply to acts committed with specific wrongful intent or as part of a common plan to commit a tortious act. § 85-5-7(1) and (4).
