Can I get a court-appointed lawyer for murder (first vs second degree) in Illinois?
Illinois's rule on court-appointed lawyers: Under Illinois Supreme Court Rule 401(a), an indigent defendant has the right to appointed counsel whenever the charge is punishable by imprisonment. The trial judge appoints the county Office of the Public Defender, which assigns the individual assistant public defender. Whether a person is indigent is left to the trial court's discretion based on as complete a financial picture as possible; a person need not be entirely without funds to be found indigent, and a court may not refuse appointment solely because the defendant posted bail. The Office of the State Appellate Defender handles appeals for indigent defendants. Ill. S. Ct. R. 401(a); People v. Campbell, 224 Ill. 2d 80 (2007); Burnette v. Terrell, 232 Ill. 2d 522 (2009); People v. Ellis, 309 Ill. App. 3d 443 (1999); People ex rel. Baker v. Power, 60 Ill. 2d 151 (1975)

The court must revisit continued detention at later hearings. 725 ILCS 5/110-6.1 (P.A. 101-652, 102-1104); Rowe v. Raoul, 2023 IL 129248 What happens after an arrest.
