CUE: Clear and Unmistakable Error

What Is CUE?

A CUE motion attacks the validity of a prior final VA decision. Unlike a Supplemental Claim or appeal (which look forward and require new evidence), CUE looks backward at what the VA did at the time and argues the decision was wrong on its face, based on the law and evidence as they existed when the decision was made.

If a CUE motion succeeds, the original decision is reversed and the effective date moves back to the date that decision should have used. Some CUE awards exceed $500,000 in retroactive pay because they unlock decades of back compensation.

The Three-Part Test (Russell v. Principi)

The Veterans Court set out the controlling CUE test in Russell v. Principi, 3 Vet. App. 310 (1992), refined by Bustos v. West, 179 F.3d 1378 (Fed. Cir. 1999):

1. Either the correct facts as known at the time were not before the adjudicator, OR the statutory or regulatory provisions extant at the time were incorrectly applied.
2. The error must be "undebatable", not merely a different conclusion that reasonable adjudicators could disagree about.
3. The error must be of the sort which, had it not been made, would have manifestly changed the outcome at the time it was made.

All three prongs must be satisfied. Failure on any one defeats the CUE motion.

What Counts as CUE

Examples of arguments that have succeeded as CUE in BVA and Veterans Court decisions:

• Misapplication of an express regulatory rule. VA assigned a 30% rating when the schedular criteria for the symptoms of record clearly required 50%.
• Ignoring evidence in the file. A nexus letter from a private physician was in the C-file at the time, addressed every element of service connection, and the rating decision failed to discuss it.
• Using the wrong rating schedule edition. VA applied the 2005 rating criteria when the 1995 version (more favorable) was in effect at the time of claim.
• Failure to apply a presumption. Veteran was a Vietnam in-country boots-on-ground veteran with a presumptive Agent Orange condition, and VA failed to apply the § 3.309(e) presumption.
• Math error on the rating schedule. VA combined two ratings of 30% and 30% to arrive at 50%, but § 4.25 combined-ratings table shows 51% (rounds to 50%, but matters in close cases), when the correct figure was 51%, then combined with another rating, the totals shift.

What Does NOT Count as CUE

The Federal Circuit's Cook v. Principi case is the leading authority that breach of the duty to assist cannot constitute CUE. This narrows the field of viable CUE motions significantly.

CUE in BVA Decisions

CUE in regional-office decisions follows § 3.105(a). CUE in BVA decisions follows a parallel but separate process under 38 CFR § 20.1400-1411. The substantive standard is the same (Russell three-part test), but the motion is filed directly with the Board, not the regional office.

If a regional-office decision was affirmed by the BVA, the appropriate target is usually the BVA decision (since it superseded the RO decision). Filing CUE against the RO decision when the BVA already ruled on the same issue may be procedurally improper.

How to File a CUE Motion

1. Obtain your full C-file. See the Records Request Guide. CUE depends on what was in the file at the time, so you need the contemporaneous record.
2. Identify the specific final decision being attacked by date and rating-decision identifier.
3. State the specific error in writing. Generic "VA got it wrong" pleadings fail. Identify exactly which fact or which regulation, and exactly how it was misapplied.
4. Explain why the error meets all three Russell prongs, undebatable, manifestly changed outcome, based on contemporaneous law and evidence.
5. For RO decisions, file with the RO. For BVA decisions, file VA Form 10182 with the Board (or the appropriate motion under § 20.1404).
6. Specify the relief sought, usually reversal of the original decision and assignment of an earlier effective date.

Evidence Patterns

Successful CUE motions almost always involve:

• Side-by-side comparison of the original rating decision and the relevant regulation/statute as it existed at the time, showing the misapplication.
• Direct citation to evidence in the C-file at the time that the original decision overlooked or contradicted.
• Citation to controlling case law from the Veterans Court or Federal Circuit interpreting the relevant regulation in the way the CUE motion proposes.
• Old M21-1 manual provisions that were in effect at the time, these often establish the duty the original decision violated.

Effect of a Successful CUE

A successful CUE motion reverses the original decision and substitutes the decision that should have been made. Effects:

• Original effective date restored, back pay calculated to the date the original decision should have used.
• If the rating was understated: the higher rating is awarded retroactively to the original effective date.
• If the claim was denied: service connection is granted with the original effective date.
• Compensation is recalculated using historical pay rates with COLA adjustments. Use the Back Pay Estimator to model.

CUE awards routinely exceed $100,000-$500,000 because they often unlock decades of back pay.

Common Mistakes

• Filing CUE based on new evidence. If you have new evidence, file a Supplemental Claim, not CUE.
• Filing CUE based on subsequent legal developments. Use a liberalizing-law claim or Supplemental Claim. CUE is judged under the law at the time of the original decision.
• Vague pleadings. "VA was wrong" is not a CUE motion. Identify the exact error, the exact regulation, the exact evidence ignored or misapplied.
• Failing to obtain the C-file. CUE depends on what was in the file at the time. File a FOIA / Privacy Act request first.
• Confusing CUE with the duty to assist. Per Cook v. Principi, breach of duty to assist is not CUE.
• Targeting the wrong decision. If a BVA decision affirmed the RO, target the BVA decision under § 20.1400, not the RO under § 3.105.
