π¨ Resisting or obstructing a peace officer is a Class A misdemeanor in Illinois under 720 ILCS 5/31-1 β even if you were never charged with anything else.
Under 720 ILCS 5/31-1(a), it is a crime to knowingly resist or obstruct a peace officer's performance of an authorized act. A Class A misdemeanor carries up to 364 days in jail and a fine up to $2,500. If the alleged resistance is claimed to have proximately caused an injury to the officer, the charge becomes a Class 4 felony (1 to 3 years in prison). Illinois courts require a physical act of resistance or obstruction; arguing, protesting verbally, or simply being uncooperative is generally not enough. These charges often follow a traffic stop, a domestic call, or a DUI arrest, and a conviction can create a criminal record that affects jobs, housing, and licensing. Defenses can include the officer's act not being authorized, lack of a knowing act, and mistaken accounts in the police report.
