How to File an MSPB Appeal for FERS Disability Retirement

OPM denied your reconsideration. The administrative process at OPM is over, and your next step is the Merit Systems Protection Board. Filing an MSPB appeal shifts your case from an internal OPM review to an adversarial legal proceeding before an Administrative Judge — a different process with different rules, different deadlines, and a hearing where you can present witnesses and cross-examine OPM's evidence.

The 30-Day Filing Deadline

Your MSPB appeal must be filed within 30 calendar days of the effective date of OPM's final reconsideration decision, or 30 calendar days after you received the decision — whichever is later. If the 30th day falls on a weekend or federal holiday, the deadline extends to the next business day.

This is a strict filing deadline. Under 5 CFR 1201.22(c), a late appeal may be dismissed unless you show a good reason for the delay.

Filing Through e-Appeal Online

The MSPB's electronic filing system is at e-appeal.mspb.gov. Create an account, select "File a New Appeal," and follow the prompts. You'll need to upload OPM's final reconsideration decision and identify the MSPB Regional or Field Office with geographic jurisdiction over your duty station or current residence.

Electronic filings are date-stamped by the time of submission — no postal delay to worry about. If you prefer paper, you can submit by postal mail, commercial delivery, or fax to the appropriate regional office. Paper filings sent via standard mail are date-stamped by the postmark.

What Happens After Filing

The assigned Administrative Judge issues an Acknowledgment Order confirming receipt and assigning a docket number. The order directs OPM to submit the complete administrative file — your entire application record, the medical officer's notes, and all evidence considered during the initial review and reconsideration. This is called the Rule 4(b) file.

The Acknowledgment Order also establishes initial litigation deadlines and outlines the burden of proof. In a standard case, you bear the burden of proving entitlement by a preponderance of the evidence. If your agency removed you for medical inability, the Bruner presumption shifts the burden of production to OPM — raise this in your initial filing if it applies.

Discovery and the Hearing

Both parties can engage in formal discovery under 5 CFR 1201.71–1201.75. You can request production of documents (compelling OPM or your agency to produce unredacted personnel files), send interrogatories (written questions requiring sworn responses), request admissions of specific facts, and even take depositions of OPM medical consultants.

The AJ conducts a prehearing conference to simplify issues and may offer settlement through the MSPB's Mediation Appeals Program. The hearing itself — typically conducted by video conference or telephone — is adversarial: the AJ administers oaths, receives documentary evidence, and hears witness testimony. This is your opportunity to present medical expert testimony and challenge OPM's rationale directly.

After the hearing, the AJ issues a written Initial Decision. The PFR deadline is generally 35 calendar days after issuance. If you can show you received the decision more than 5 days after it was issued, you have 30 days from receipt to file. If neither party files a timely Petition for Review, the Initial Decision becomes final.

Pro Se or With Counsel

You have the right to represent yourself before the MSPB. The question is whether your case's complexity warrants legal representation. If your case involves the Bruner presumption, competing medical opinions, or novel legal questions, an attorney familiar with MSPB procedures can be valuable during discovery and the hearing itself.

The FERS Disability Denial Appeal Guide provides step-by-step instructions for the e-Appeal portal, discovery request templates, and hearing preparation frameworks for both represented and pro se appellants.
