Background
Christian Weis, a coal miner employed by Blackhawk Mining, LLC, filed a workers’ compensation claim for a compensable injury. The claim administrator issued an order on October 24, 2023, granting Weis a 12% permanent partial disability (PPD) award. Weis challenged that determination, and competing medical opinions were submitted: Dr. Prasadarao B. Mukkamala on behalf of the employer and Dr. Bruce A. Guberman on behalf of the claimant, each offering multiple alternative impairment calculations.
The West Virginia Workers’ Compensation Board of Review reversed the claim administrator and awarded an additional 3%, bringing the total PPD award to 15%. The Board found that although Dr. Guberman had made a calculation error under the range-of-motion model, that error did not undermine the reliability of his overall opinion because his recommended award was based instead on atrophy and scarring — a methodology the Board found consistent with the AMA Guides to the Evaluation of Permanent Impairment (4th ed. 1993). The Board concluded that both physicians’ opinions carried equal evidentiary weight and, invoking West Virginia Code § 23-4-1g(a), adopted the resolution most favorable to the claimant.
Blackhawk Mining appealed to the Intermediate Court of Appeals of West Virginia (ICA), which affirmed the Board of Review by memorandum decision on October 24, 2025. Blackhawk then petitioned the Supreme Court of Appeals, arguing that Dr. Guberman’s error disqualified his opinion from equal-weight status and that his 15% atrophy-and-scarring rating was arbitrary and unexplained.
The Court’s Holding
The Supreme Court of Appeals unanimously affirmed, finding no reversible error and issuing a summary memorandum decision under West Virginia Rule of Appellate Procedure 21. The Court applied de novo review to questions of law and deferred to the Board of Review’s factual findings unless clearly wrong, consistent with its standard articulated in Duff v. Kanawha County Commission, 250 W. Va. 510, 905 S.E.2d 528 (2024).
The Court accepted the Board of Review’s determination that Dr. Guberman’s range-of-motion calculation error was immaterial because his ultimate impairment recommendation rested on atrophy and scarring, not range of motion. Because the Board had found the two physicians’ opinions equally reliable and of equal evidentiary weight, West Virginia Code § 23-4-1g(a) required adoption of the claimant-favorable resolution — the 15% PPD award.
Key Takeaways
- A physician’s calculation error under one impairment model does not automatically render the physician’s entire opinion unreliable if the recommended award is grounded in a separate, independently valid model.
- When the Board of Review finds competing medical opinions to be of equal evidentiary weight, West Virginia Code § 23-4-1g(a) mandates that the tie be broken in the claimant’s favor.
- The Board of Review’s factual findings — including reliability assessments of expert medical opinions — receive deference on appeal and will not be disturbed unless clearly wrong.
Why It Matters
This decision reinforces the practical force of West Virginia’s workers’ compensation tie-breaker statute, § 23-4-1g(a), which functions as a statutory thumb on the scale for claimants whenever medical evidence is in equipoise. Employers and their medical experts cannot neutralize an adverse opinion merely by identifying a subsidiary calculation error; so long as the physician’s overall rating stands on an independent, valid basis, the opinion retains full evidentiary weight.
For practitioners, the case signals that challenging an opposing expert on a single methodological point is unlikely to succeed unless that error infects the physician’s ultimate impairment recommendation. Employers seeking to overcome a claimant-favorable Board ruling face the additional hurdle of the statutory default, making it critical to secure medical opinions that are unambiguously stronger — not merely equal — to those offered by claimants.
