(a) For purposes of this article, "comparative fault" means the degree to which the fault of a person was a proximate cause of an alleged personal injury or death or damage to property, expressed as a percentage. Fault shall be determined according to section thirteen-c of this article.
(b) In any action based on tort or any other legal theory seeking damages for personal injury, property damage, or wrongful death, recovery shall be predicated upon principles of comparative fault and the liability of each person, including plaintiffs, defendants and nonparties who proximately caused the damages, shall be allocated to each applicable person in direct proportion to that person's percentage of fault.
(c) The total of the percentages of comparative fault allocated by the trier of fact with respect to a particular incident or injury must equal either zero percent or one hundred percent.
