Defense counsel in an Illinois DUI case can obtain a broad range of material through Rule 412 discovery and subpoena. Available items include the police report, sworn report under 625 ILCS 5/11-501.1, squad dashcam and station video, body cam footage, breath machine accuracy check history and certification, operator permits, blood test lab worksheets, chain-of-custody documents, hospital records for medical draws, 911 audio, CAD dispatch logs, officer training records including NHTSA certification, and personnel history including sustained integrity findings. Independent expert analysis of raw data is often warranted. A Chicago DUI lawyer maps the subpoena list against the state's theory and pulls the records that hurt the state's proof.
