One of the prinicples underlying our legal system is efficiency. It therefore comes as no surprise that the common policy is to restrict the admissibility of opinion evidence except in cases where it will be neccessary or helpful. In the case of opinion testimony by expert witnesses, the admissibility of an opinion or conclusion must be predicated on satisfaction of the following conditions:
1) scientific, technical, or other specialized knowledge would assist the trier of fact in understanding the evidence or deciding on an issue;
2)the opinion must be relevant to the facts of the case; and
3) the methodology underlying the expert opinion must be reliable (a number of factors go into certifying an expert opinion as reliable).
The facts or data presented to an opinion expert can be made known to an expert at or before a hearing or trial. If the facts presented to the expert are of a type reasonably relied on by experts in the field, the facts need not be admissible in evidence.
Despite general restrictions on the admissibility of opinion experts, the Illinois Rules of Evidence still give a fair amount of latitude to opinion experts in the formulation of their opinions. Contact a Chicago Illinois Personal Injury Attorney in order to navigate the gauntlet of Illinois evidence law.
