Even if we were to deem respondent's notice of appeal as a request for leave to appeal the September 10, 2020, order, it is untimely and ineffective to confer jurisdiction under Rule 306(a)(5). Accordingly, we lack jurisdiction to consider respondent's contentions regarding the September 10, 2020, order, and we dismiss this portion of the appeal. River Breeze, LLC v. Granholm, 2022 IL App (2d) 210704, ¶ 18 (the court has the duty to examine its jurisdiction even if no party has challenged it, and to dismiss the appeal or a portion of the appeal if it lacks jurisdiction).
