Illinois courts and expert standards

Illinois courts ask whether the methodology behind an expert opinion is generally accepted in the relevant professional community, and separately whether the economist is qualified by training and experience and applied the method to the facts of the case. Forensic economic methods for lost earnings, worklife, and present value are published and long used, so the examination usually turns on the inputs and their support in the record.

Where these cases are heard

Highest court: Illinois Supreme Court. Federal venues: N.D. Ill., C.D. Ill., S.D. Ill. Court system: illinoiscourts.gov.

Damages framework

Illinois reduces a negligence-based award by the plaintiff's share of fault and bars recovery once that share exceeds half. Prejudgment interest on a personal injury or wrongful death award runs from the filing of the action, and interest on a written instrument or a liquidated contract sum runs at the statutory rate from the date it was due. Economic damages are not subject to a general statutory limit, so the report states each loss as of a fixed date and separates past from future amounts so the interest computation can follow.

How the analysis is built

The same four steps apply to a commercial contract dispute case venued in Illinois; the damages framework above decides which components enter the total.

  1. Establish the but-for revenue from the contract terms, the pre-dispute projections, and the business's own history.
  2. Identify the incremental costs that would have been incurred to earn that revenue so that only the lost margin is claimed.
  3. Analyze actual results after the breach to separate the effect of the breach from market conditions and other causes, and credit mitigation revenue.
  4. Bring past lost profits forward and discount future lost profits at a stated rate that reflects the risk of the earnings stream.
