People v. Deroo
Annotate this Case
After a night of drinking, Deroo drove his car off the road, flipped several times, and crashed into a ditch. He was taken to the hospital by ambulance. Deroo was convicted of aggravated driving under the influence (DUI) and aggravated driving while his license was revoked and sentenced to concurrent terms of imprisonment of nine and three years, respectively. At trial, the results of a blood test establishing his blood alcohol content were admitted into evidence under the Illinois Vehicle Code (625 ILCS 5/11-501.4(a)), which allows the admission of chemical tests of blood conducted in the course of emergency medical treatment “as a business record exception to the hearsay rule.” Deroo argued that section 11-501.4(a) conflicted with Illinois Rule of Evidence 803(6), which excluded “medical records in criminal cases” from the business records hearsay exception.
The appellate court found no conflict and affirmed. The Illinois Supreme Court affirmed, concluding that Rule 803(6)'s medical records exclusion for criminal cases is not logically defensible. The court amended that Rule, striking the exception and stating that ordinary rules of evidence do not violate the Ex Post Facto Clause because by simply permitting evidence to be admitted at trial, they do not at all subvert the presumption of innocence.
