IllinoisPeople v. Heintz

January 28, 20262026 IL 131340

The court held that Illinois Rule of Evidence 405(b)(2) permits evidence of an alleged victim's specific violent conduct only when it occurred before the charged offense, so the trial court properly excluded the victim's later conduct.

The court affirmed the denial of Katrina’s motion to substitute herself for Dobbins and the dismissal of his certificate-of-innocence petition.

IllinoisPeople v. Chambliss

January 23, 20262026 IL 130585

The Illinois Supreme Court held that the trial court's failure to provide a prompt preliminary hearing did not constitute second-prong plain error because the error was harmless when the defendant was later convicted after a fair jury trial.

It also concluded that substantial evidence supported the Commission’s finding that Grain Belt Express could finance the project without significant…

IllinoisPeople v. Butler

November 20, 20252025 IL 130988

November 20, 20252025 IL 131420

The Illinois Supreme Court held that the school district and its teacher were immune from liability under section 3-108 of the Tort Immunity Act because the evidence established, at most, negligent failure to supervise, not willful and wanton conduct.

IllinoisFausett v. Walgreen Co.

November 20, 2025280 N.E.3d 221

The court held that the plaintiff lacked common-law standing to pursue her FACTA claim because, after discovery, she established at most a speculative increased risk of identity theft rather than a concrete injury.

IllinoisPeople v. Class

August 28, 20252025 IL 129695

The court held that an appellate court may order reassignment of a circuit judge on remand in a postconviction proceeding, but only when the record clearly demonstrates actual bias, a probability of bias, or prejudice.

IllinoisPeople v. Muhammad

July 10, 20252025 IL 130470

The Illinois Supreme Court held that Muhammad's alleged statements fall within the Torture Inquiry and Relief Commission Act's broad definition of a tortured confession, even though Muhammad denied making them, and therefore judicial review and an evidentiary hearing were warranted.
