An independent guide to federal sentencing law and procedure in Chicago, Cook County — the local federal courthouse, the sentencing process, and how guideline ranges are calculated.
U.S. District Court — Northern District of Illinois
219 S Dearborn Street, Chicago, IL 60604
Federal sentencing in every district follows the same structure: a base offense level, specific offense characteristics, a criminal history category, and the statutory factors under 18 U.S.C. § 3553(a). Local practice — from PSR procedures to courtroom norms — varies by courthouse.
Base offense levels, specific offense characteristics, cross-references, and relevant conduct.
Substantial assistance (5K1.1), aberrant behavior, diminished capacity, coercion, and other grounds for below-range sentences.
Post-Booker variance arguments based on the statutory sentencing factors.
Challenging the Presentence Investigation Report — factual inaccuracies and guideline application errors.
No. Since United States v. Booker (2005), the guidelines are advisory, not mandatory. Judges must calculate the guideline range but may impose a sentence outside it.
A downward departure is a sentence below the guideline range based on circumstances recognized by the guidelines, such as substantial assistance or aberrant behavior.
Relevant conduct under USSG 1B1.3 can include uncharged and even acquitted conduct. This can dramatically increase the guideline range.
