The Impact of Victim's Predisposition on Civil Liability of Tortfeasor

In this research we have tried to investigate if the victim’s predisposition would influence civil liability of tortfeasor. In exact words “Predisposition” means the unusual physical situation of the victim before damages are incurred to him. Sometimes the tortfeasor intensify victim’s unusual situation and sometimes he changes the nature of his disability. We reached to a conclusion according to which, except causing perfect blindness which is effective in intensifying tortfeasor’s liability, in other situations, predisposition is effective in reducing tortfeasor’s liability. As a result, we should suffice to strict interpretation in the case of blindness.
