15 U.S. Code § 6605 - Proportionate liability
Except in a Y2K action that is a contract action, and except as provided in subsections (b) through (g) of this section, a person against whom a final judgment is entered in a Y2K action shall be liable solely for the portion of the judgment that corresponds to the relative and proportionate responsibility of that person. In determining the percentage of responsibility of any defendant, the trier of fact shall determine that percentage as a percentage of the total fault of all persons, including the plaintiff, who caused or contributed to the total loss incurred by the plaintiff.
The responses to interrogatories or findings under paragraph (1) shall specify the total amount of damages that the plaintiff is entitled to recover and the percentage of responsibility of each defendant found to have caused or contributed to the loss incurred by the plaintiff.
Nothing in this section affects the right, under any other law, of a defendant to contribution with respect to another defendant found under subsection (b)(1)(B) of this section, or determined under paragraph (1)(B) of this subsection, to have acted with specific intent to injure the plaintiff or to have knowingly committed fraud.
For a plaintiff not described in clause (i), each of the other defendants is liable for the uncollectible share in proportion to the percentage of responsibility of that defendant.
For a plaintiff not described in clause (i), in addition to the share identified in clause (ii), the defendant is liable for an additional portion of the uncollectible share in an amount equal to 50 percent of the amount determined under clause (ii) if the plaintiff demonstrates by a preponderance of the evidence that the defendant acted with reckless disregard for the likelihood that its acts would cause injury of the sort suffered by the plaintiff.
The total payments required under subparagraph (A) from all defendants may not exceed the amount of the uncollectible share.
A defendant against whom judgment is not collectible is subject to contribution and to any continuing liability to the plaintiff on the judgment.
A defendant who is jointly and severally liable for damages in any Y2K action that is not a contract action may recover contribution from any other person who, if joined in the original action, would have been liable for the same damages. A claim for contribution shall be determined based on the percentage of responsibility of the claimant and of each person against whom a claim for contribution is made.
An action for contribution in connection with a Y2K action that is not a contract action shall be brought not later than 6 months after the entry of a final, nonappealable judgment in the Y2K action, except that an action for contribution brought by a defendant who was required to make an additional payment under subsection (d)(1) of this section may be brought not later than 6 months after the date on which such payment was made.
