Representative Cases
Attorney Biddison has argued many cases in the state and federal appellate courts, resulting in precedent-setting published decisions. For example, in Oakley v. Longmont, 890 F.2d 1128 (10th Cir. 1989), he succeeded in getting the court to declare that his client, who had been severely injured in an automobile accident, was entitled to continue his medical insurance coverage under the health plan offered by his employer. This is very important to anyone who is injured and needs continuing medical care and treatment.
