The Illinois Supreme Court was reviewing a case where a defendant, after trial, made a bare bones complaint of ineffective assistance of counsel. The trial court made no inquiries of defense counsel, and denied the motion as insufficient.
The Illinois Supreme Court resolves a number of conflicts among the appellate courts, holding that when there’s a claim on ineffective assistance, the trial court must conduct a Krankel inquiry.
The case is People v. Ayres.
