Different types of Nassau New York Jury Instruction — 1.1 Comparative Negligence Defense: 1. Pure Comparative Negligence: This type of comparative negligence defense allows the jury to assign a percentage of fault to each party involved in the incident, regardless of how negligible or significant their contribution may have been. The plaintiff's recovery is then reduced by their assigned percentage of fault. 2. Modified Comparative Negligence (50% Bar Rule): Under this type of comparative negligence defense, the plaintiff can only recover damages if their assigned fault is less than or equal to the fault assigned to the defendant. If the plaintiff's assigned fault exceeds the defendant's fault, the plaintiff is barred from receiving any damages. 3. Modified Comparative Negligence (51% Bar Rule): Similar to the 50% Bar Rule, this type of comparative negligence defense prevents the plaintiff from recovering damages if their assigned fault is equal to or greater than the fault assigned to the defendant. However, the plaintiff can still recover damages if their assigned fault is less than the fault assigned to the defendant, even if it exceeds 50%. 4. Last Clear Chance Doctrine: This is a doctrine that can be considered as an exception to basic comparative negligence principles. It states that if the defendant had the last clear chance to avoid the accident or injury but failed to do so, then the plaintiff can still recover damages, even if they were partially negligent. These different types of comparative negligence defense provide the jury with guidelines to determine the extent of liability for each party involved in a personal injury case in Nassau New York. It ensures a fair and just outcome by considering the contributions and faults of each party in causing the accident or injury.
