Comparative Fault: Illinois vs. Pennsylvania

Explore how Illinois and Pennsylvania approach comparative fault, including key differences, similarities, and leading cases.

Illinois (IL) Approach

Illinois adopts a modified comparative fault system. Under 735 ILCS 5/2-1116, a plaintiff's recovery is barred if they are found to be more than 50% at fault for the accident. If the plaintiff is 50% or less at fault, their damages are reduced by their percentage of fault. For example, if a plaintiff is awarded $100,000 but is found to be 30% at fault, they would recover $70,000. This approach encourages personal accountability while still allowing recovery for partially at-fault parties.

The Illinois system is further supported by case law which reiterates the importance of presenting credible evidence to establish fault percentages. Courts often emphasize examining the conduct of both the plaintiff and defendant to determine liability. The modified comparative negligence standard aims to balance the need for justice with the realities of shared responsibility in tort cases.

Pennsylvania (PA) Approach

Pennsylvania uses a different approach, also known as modified comparative negligence, under 42 Pa. Cons. Stat. § 7102. Pennsylvania's rule establishes that a plaintiff's recovery is barred only if they are found to be more than 50% at fault, aligning closely with Illinois. However, unlike Illinois, Pennsylvania allows the recovery to be reduced according to the plaintiff's degree of fault even if that fault is equal to the defendant's. For instance, if a plaintiff is found 50% at fault, they can still recover damages, which would be reduced by 50%. This policy operates under the principle that both parties can share the responsibility without preventing recovery solely based on equal fault.

Pennsylvania courts have reaffirmed this principle in various rulings, emphasizing the need for clear evidence of fault allocation. This aspect of the law reinforces the equitable treatment of plaintiffs and encourages fair settlements in personal injury cases, allowing for cases to be evaluated based on the nuanced conduct of each party involved.

Key Similarities

  • Illinois courts strictly enforce the 50% rule, whereas Pennsylvania permits partial recovery even at equal fault levels.
  • The method of applying fault percentages may differ in judicial interpretations and precedents between both states.
