How do I appeal an unemployment insurance denial in Colorado?

1. Agency. The Colorado Department of Labor and Employment (CDLE), Division of Unemployment Insurance, administers UI under the Colorado Employment Security Act (C.R.S. § 8-70-101 et seq.).

2. Common Disqualifications. Voluntary quit without good cause (C.R.S. § 8-73-108(4)), discharge with full or partial responsibility for separation (§ 8-73-108(5)), refusal of suitable work (§ 8-73-108(4)(b)(II)), not able and available (§ 8-73-107), or receipt of severance.

3. Determination Notice. CDLE mails a Notice of Decision through MyUI+ stating the reason for the disqualification and appeal rights.

4. Appeal Deadline. 20 calendar days from the mailing date of the deputy's decision (C.R.S. § 8-74-104). Late appeals require good cause.

5. Filing the Appeal. File through MyUI+ online, by mail to the Appeals Section, by fax, or in person.

6. First-Level Hearing. The Division of Hearings (CDLE) conducts a telephonic de novo hearing before a Hearing Officer (C.R.S. § 8-74-106). Both parties testify under oath, submit documents, and cross-examine.

7. Burden of Proof. Employer bears the burden on discharge issues; claimant bears the burden on good-cause voluntary quit.

8. Decision. The Hearing Officer issues a written decision typically within 30 days.

9. Second-Level Administrative Appeal. Appeal to the Industrial Claim Appeals Office (ICAO) within 20 days (C.R.S. § 8-74-104(2)); review is on the record.

10. Judicial Review. Appeal to the Colorado Court of Appeals within 21 days under C.R.S. § 8-74-107 and § 24-4-106(11); review is on the substantial-evidence standard.

11. Continued Filing. Continue weekly certifications through MyUI+ during the appeal to preserve back pay.

12. Overpayment. If you lose, CDLE issues an overpayment notice; non-fault waiver is narrowly available (C.R.S. § 8-81-101); fraud overpayments carry a 65% penalty.
