In Illinois workers' compensation cases, a petition for rehearing asks the Workers' Compensation Commission—or, in limited circumstances, an appellate court—to reconsider a prior decision. This overview explains the typical format, key sections, filing deadlines, and procedural rules you must follow. Use these evergreen requirements to prepare a complete petition that clearly explains what needs to be reconsidered and why. The rules described here apply to Commission rehearing requests and common practices for subsequent appellate review.

When and Where to File a Petition for Rehearing
Before formatting, confirm the correct forum and deadline. For Commission orders, you generally must file a petition for rehearing within 30 days after the date of the order. For final orders or certain appellate rulings, you may seek leave to appeal or file a motion for rehearing depending on the court. Always verify current statute and rule citations with the current Illinois Workers' Compensation Act and the Illinois Rules of Appellate Procedure. Filing late without extension or good cause typically waives the right to challenge the order on rehearing grounds.
Key Filing Deadlines and Venue
| Order Type | Typical Deadline | Where to File |
|---|---|---|
| Commission Order (non-final) | 30 days from date of order | Workers' Compensation Commission, Docket Management |
| Final Commission Order | 30 days; may appeal thereafter | Commission, then circuit court if appeal taken |
| Appellate Court Decision | Leave to appeal or motion for rehearing per rules | Appellate court clerk |
Required Elements of the Petition Format
A well-formatted petition for rehearing is concise, factual, and clearly focused on why the prior decision was incorrect or incomplete. Use a legible font, 1-inch margins, and numbered pages. Begin with a caption that includes the case name, case number, and designation (e.g., Petition for Rehearing). The body should include: an introduction identifying the order being challenged; a numbered statement of the specific issues you ask the Commission or court to reconsider; a factual and legal argument section explaining why the earlier decision was wrong; and a prayer for relief that precisely states what you want the tribunal to do. Attach any supporting exhibits referenced in your arguments, and include a certificate of service showing how and when you served the opposing party.
Caption and Header Information
Every pleading in Illinois workers' compensation proceedings should open with a properly formatted caption. Include the name of the Commission or court, the title of the case (claimant v. employer), the case number, and the title of the document (e.g., Petition for Rehearing). Place a header with the case name and number on each page. These formalities ensure the filing is assigned correctly and reviewed without delay.
Statement of Issues to Be Reconsidered
Clearly list each issue you want reconsidered. Use concise headings or bullet points such as 'Issue I: Eligibility,' 'Issue II: Weekly Benefits,' or 'Issue III: Valuation of Permanent Impairment.' For each issue, briefly cite the statute or rule you believe was misapplied. This structure helps the Commission or court quickly locate the specific holdings you dispute and avoids unnecessary narrative that can obscure your points.
Content and Argument Guidelines
In the argument section, refer to the record: cite the transcript pages, exhibits, claims history, and the prior decision you are challenging. Explain how the record supports your position and identify specific errors of fact or law. If you are challenging a Commission decision that already corrected a prior error, explain why the new decision still misconstrued the evidence or law. If you are appealing to a court, frame arguments in terms of clear error, abuse of discretion, or whether the order complies with the Workers' Compensation Act. Avoid conclusory statements; instead, use specific citations to sections of the Act, Commission precedent, and the record.
Fact-Check and Record Citations
| What to Cite | How to Reference | Purpose |
|---|---|---|
| Specific transcript pages | Tr. at p.XX | Pin down testimony or evidentiary rulings |
| Exhibit numbers | Ex. 5, ¶ 12 | Point to documentary evidence |
| Claims history entries | CH entry dated MM/DD/YYYY | Show procedural context |
| Statutory sections | 820 ILCS 130/5-10 | Anchor arguments in the Act |
Prayer for Relief and Proposed Orders
The prayer for relief should state exactly what you want the tribunal to do. Examples: 'Petitioner respectfully prays that this Court set aside the Order of September 1, 20XX and remand for further proceedings consistent with this petition,' or 'Reconsider the Commission's decision denying temporary total benefits and award benefits pursuant to Section X.' If you are seeking specific monetary amounts or non-monetary relief (e.g., medical benefits, vocational rehabilitation), itemize them. A clear, precise prayer reduces the chance that your request is modified or denied on form grounds.
Service, Filing, and Additional Procedural Steps
File the petition with the proper clerk and pay any required fees, or request a fee waiver if eligible. Serve a copy on all parties in accordance with Commission or court rules—typically by mail and electronic filing if available. Keep proof of service and a stamped copy of the filed petition. Consider including a proposed order for the tribunal to sign if the relief is straightforward. Because rules can evolve, verify current filing procedures on the official Commission or appellate court website before you submit.
