Can I get a court-appointed lawyer for sexual assault and rape 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)

How release before trial works in Illinois: Illinois abolished cash (monetary) bail under the Pretrial Fairness Act (part of the SAFE-T Act); cash bail ended in Illinois courts on September 18, 2023, after the Illinois Supreme Court upheld the law in Rowe v. Raoul, 2023 IL 129248. The default is pretrial release on personal recognizance, with conditions. The State may seek detention only in specified cases by filing a petition; at the first detention hearing the State must prove by clear and convincing evidence that the proof is evident or the presumption great that the defendant committed a detainable offense, that the defendant poses a real and present threat to any person or the community or a high likelihood of willful flight, and that no conditions could mitigate that threat or risk. 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.
