Summary

In this parentage action under the Illinois Parentage Act of 2015, the circuit court of Cook County entered an allocation of parental responsibilities, parenting plan, and child support orders on April 24, 2024. Respondent Sarah Brown, the biological mother, failed to file a timely notice of appeal within 30 days as required by Illinois Supreme Court Rule 303(a), and also failed to file a motion for leave to file a late notice of appeal by the June 24, 2024 deadline imposed by Rule 303(d). Instead, Brown filed her motion for leave on May 28, 2025 — more than a year after the orders were entered. The appellate court had initially granted that motion on June 4, 2025, but upon further review vacated that order as improvidently granted.

The court dismissed the appeal for lack of jurisdiction, emphasizing that it has no authority to excuse a party's failure to comply with supreme court rules governing appellate deadlines. The court also found that Brown's brief failed to satisfy nearly every requirement of Rule 341(h), including the absence of a jurisdictional statement, cogent argument, accurate statement of facts, and identification of relief sought. Although the court acknowledged it could dismiss on briefing deficiencies alone, it declined to do so, resting dismissal solely on jurisdictional grounds.

This case serves as a critical reminder that appellate deadlines in family law matters are strictly enforced, that courts have an independent duty to assess jurisdiction, and that even a previously granted order allowing a late appeal can be vacated if the underlying motion was itself untimely.

Key Holdings

1. An appellate court lacks jurisdiction over an appeal from an allocation of parental responsibilities order when the appellant fails to file a notice of appeal within 30 days under Rule 303(a) and fails to file a motion for leave to file a late notice of appeal within 30 days after that deadline under Rule 303(d).

2. A motion for leave to file a late notice of appeal filed over a year after the entry of the final order — when the deadline under Rule 303(d) had long passed — is untimely, and the appellate court has no authority to grant it.

3. An appellate court order granting leave to file a late notice of appeal must be vacated as improvidently granted where the underlying motion was itself filed outside the time limits prescribed by Rule 303(d).

4. Pro se litigants are held to the same procedural standards as attorneys, including compliance with Rule 341(h) briefing requirements, though the court may decline to dismiss solely on that basis when dismissal for lack of jurisdiction is independently warranted.
