When may an Illinois party petition a reviewing court for rehearing?

Obtain actual reviewing-court judgment filing rather than service or notice.

Identify the overlooked or misapprehended points and precise record and brief references.

Check prior rehearing disposition and actual orders changing time.

1. Obtain actual reviewing-court judgment filing rather than service or notice.
2. Exclude the independently established triggering day and count intermediate calendar days under 5 ILCS 70/1.11. A filing, entry, effective service or previously established due date must come from its actual record. Do not substitute one event for another.
3. Check statutory holidays and the proper court’s actual calendar.
4. Complete the particular act in the proper court.

Section 1.11 excludes a final Saturday, Sunday or statutory holiday and consecutive excluded days. Section 17(a) of the Promissory Note and Bank Holiday Act includes Pulaski Day, Good Friday and the general election for members of the House of Representatives. Check proclamations, the proper court’s actual calendar and clerk access separately. The bundled Illinois calendar covers 2026 and 2027.

Fictitious example

Fictitious facts. The appeal classification and triggering event are independently established. No additional closure, court order or unmodeled restart is assumed.

A petition addresses overlooked or misunderstood points

Rule 367(b) requires concise points, proper references to the record and brief, and authorities and argument. It prohibits reargument of the case.

Extensions face an express restrictive standard

Rule 367(a) allows a changed period only through actual court action and permits extensions only in the most extreme and compelling circumstances.

Form, length and service require compliance

Rule 367(a), (c) ordinarily sets twenty-seven pages or eight thousand one hundred words, a compliance certificate, brief form and service, and duplicate paper copies if required.

Further Appellate Court rehearing petitions are prohibited

After the Appellate Court acts on a rehearing petition and enters judgment on rehearing, Rule 367(e) prohibits another petition in that court.

• The calculator does not decide appealability, disputed facts, sufficiency of a filing or whether the court grants relief.
• Check the governing edition and actual orders. A current rule does not establish every historical appeal’s timetable.

• File the petition with the reviewing court and complete required brief-form service and proof. Unless authorized otherwise, observe twenty-seven pages or eight thousand one hundred words and the Rule 341(c) compliance certificate. Supply duplicate paper copies if required. Preserve judgment filing, prior rehearing history and actual relief. Use the proper clerk and required filing format. Rule 9 ordinarily requires electronic filing in civil cases, subject to its exceptions and exemptions. Rule 9(f) ordinarily uses submission before midnight in the court time zone, unless a statute, rule or order sets a particular time. A submission when the clerk is closed is ordinarily stamped on the next open day. Current Rule 9(f) provides separate five-court-day motions for a rejected filing or qualifying technical failure; establish the actual notice, failure, corrected document and required proof. Rule 373 ordinarily uses actual receipt, with its mail or carrier exception limited to filings excepted or exempt from electronic filing. Its carrier branch requires delivery for receipt within three business days and Rule 12(b) proof. Filing and service remain separate acts. Use Rule 11’s applicable service method and file Rule 12 proof. Rule 12(c) makes electronic or personal delivery service effective on its stated day, mail service complete four days after mailing, and third-party carrier service complete on the third court day after delivery to the carrier. Establish effective service before using a service-triggered calculator. A rule requiring personal or email service cannot be replaced with ordinary mail.
