Final answer:
Louisiana uses a pure comparative negligence rule where each party's financial responsibility in a lawsuit is proportional to their fault.
Step-by-step explanation:
Louisiana applies a "pure" comparative negligence meaning that each party is responsible only for the allotted share of fault. In a case where multiple parties are responsible for an injury or loss, the pure comparative negligence system allows a damaged party to recover even if it is 99% at fault, although the recovery is reduced by the damaged party's degree of fault. This contrasts with contributory negligence, where a damaged party cannot recover any damages if it is found to be even 1% at fault.
