Bruner Presumption FERS Disability: How Agency Removal Shifts the Burden to OPM

Most FERS disability retirement applicants carry the entire burden of proof — they must convince OPM that they're entitled to benefits by a preponderance of the evidence. The Bruner presumption flips that framework, and if it applies to your situation, it fundamentally changes the dynamics of your appeal.

What the Bruner Presumption Does

Under Bruner v. Office of Personnel Management, 996 F.2d 290 (Fed. Cir. 1993), when a federal agency separates an employee specifically for medical inability to perform useful and efficient service, that agency action creates a prima facie case of disability entitlement. The burden of production shifts from the applicant to OPM — meaning OPM must come forward with evidence showing you're not entitled to disability retirement.

If OPM fails to produce rebutting evidence, the presumption controls and disability retirement must be granted. If OPM does produce evidence, the presumption drops out, and the MSPB weighs the totality of the record to determine whether you've met your ultimate burden of persuasion.

When Bruner Applies

The presumption attaches when your agency separates you for medical inability to perform useful and efficient service. Review your SF-50 and the proposal and decision notices to confirm the stated reason. An agency action based on medical inability supports Bruner; a removal for unacceptable performance or conduct alone does not.

This distinction matters because some employees negotiate settlement agreements that change their separation code after the fact. OPM scrutinizes these situations. If you were removed for misconduct or performance, and a settlement later recharacterized the separation as medical, OPM will not automatically grant the Bruner presumption. You'd need compelling medical evidence showing the original removal was erroneous and the agency didn't know about the disabling condition at the time of separation.

How OPM Tries to Overcome the Presumption

OPM's most common strategy is asserting that your medical evidence lacks "objective" documentation — no MRIs, no blood panels, no imaging studies. Before April 2026, this argument carried weight in some MSPB proceedings.

The Federal Circuit's decision in Garland v. OPM (April 22, 2026) shut down that approach. The court held that OPM cannot satisfy its burden of production under Bruner merely by asserting a lack of objective clinical tests. Subjective medical evaluations — including treating physician observations, patient-reported symptoms, and clinical diagnoses using established diagnostic criteria — are competent evidence that OPM must consider. If your denial letter dismisses your physician's assessment because it lacks lab results, Garland provides direct precedent for your reconsideration brief.

How to Invoke It in Your Filing

Review your SF-50 and the removal proposal and decision notices to confirm the separation reason. If they show removal for medical inability, state the Bruner presumption explicitly in your reconsideration request or MSPB appeal. Cite the case: Bruner v. OPM, 996 F.2d 290 (Fed. Cir. 1993). State that the agency's own action establishes a prima facie case of entitlement, and that the burden of production rests with OPM.

Don't assume OPM will recognize and apply Bruner on its own. OPM adjudicators process thousands of cases, and the presumption requires you to raise it, document it, and connect it to the medical record.

The FERS Disability Denial Appeal Guide includes the specific language for invoking Bruner in both OPM reconsideration briefs and MSPB filings, along with templates for presenting the Garland precedent alongside it.
