Treating-Physician No-Work Orders Control Temporary Total Disability, and the IAB May Reopen Its Decision to Correct Legal Error

Case: United Parcel Service v. Ashley A. Smith
Court: Supreme Court of Delaware
Date: February 26, 2026
Disposition: Affirmed

1) Introduction

This workers’ compensation appeal arose from injuries sustained by Ashley A. Smith, a United Parcel Service (“UPS”) delivery driver, who fell from a UPS truck on February 3, 2022 and injured her neck and back. The parties agreed the injury occurred in the course and scope of employment, but disputed (i) whether Smith’s later neck and back surgeries were causally related to the 2022 work accident or instead to a purported second accident on February 3, 2023, and (ii) whether Smith’s temporary total disability ended in December 2023.

The Industrial Accident Board (“IAB” or “Board”) initially found the surgeries compensable but ended total disability as of December 31, 2023. On Smith’s motion for clarification, the Board issued a clarifying order reversing itself on disability duration, concluding it had misapplied Delaware law governing a claimant’s entitlement to rely on a treating physician’s instruction to stay out of work. UPS appealed, arguing (a) the Board impermissibly “altered the record” by treating inconsistent expert testimony as a mere misstatement, and (b) the Board exceeded its authority by reversing its prior disability determination. The Superior Court affirmed, and the Delaware Supreme Court did as well.

2) Summary of the Opinion

  • No “alteration of the record”: The Court held the Board permissibly weighed expert testimony, credited Smith’s treating surgeon, and treated the “2023” references as an apparent year-misstatement supported by other record evidence. Substantial evidence supported the finding that only the February 3, 2022 accident occurred.
  • Cross-examination argument rejected: UPS had the opportunity to cross-examine the treating physician during the deposition about the inconsistencies and chose not to.
  • Authority to reconsider and correct legal error: The Board had inherent authority to reopen and reconsider its decision before losing jurisdiction, and it properly corrected its misapplication of the temporary total disability rule derived from Gilliard-Belfast v. Wendy's Inc..
  • Delhaize did not narrow the treating-physician rule: The Court rejected UPS’s reading that Delhaize Am., Inc. v. Baker limited the rule such that a Board finding could terminate disability despite an ongoing no-work order; instead, the Court viewed Delaware precedent as reinforcing broad application of the rule.

3) Analysis

A. Precedents Cited

1. Standards of review and “substantial evidence”

The Court framed its review through decisions defining appellate deference to administrative factfinding:

  • Gala v. Bullock (quoting Delaware Bd. of Med. Licensure & Discipline v. Grossinger) supplied the central administrative law posture: where the Superior Court takes no new evidence, the Supreme Court examines the agency decision for substantial evidence and legal error, reviewing legal questions de novo.
  • Oceanport Indus., Inc. v. Wilm. Stevedores, Inc. defined “substantial evidence” as evidence a reasonable mind might accept as adequate—setting a deferential threshold that makes credibility and weight determinations primarily the Board’s domain.

2. Agency discretion to choose among experts

To reject UPS’s “altered testimony” framing, the Court relied on the Board’s authority to accept one expert over another:

  • Person-Gaines v. Pepco Holdings, Inc. was pivotal: it affirms that an agency may adopt one expert’s opinion over another, and that adopted opinion can constitute substantial evidence. The Court used this principle to characterize the Board’s handling of the “2023” references not as rewriting testimony, but as ordinary factfinding and credibility assessment within the Board’s discretion.

3. Inherent authority to reopen/reconsider agency decisions

The Court upheld the Board’s ability to correct its own legal error by invoking Delaware doctrine on administrative reconsideration:

  • Henry v. Dep't of Lab. supplied the governing rule: a public body exercising judicial functions has inherent power (even absent statute) to reopen and reconsider a decision until it loses jurisdiction. This directly answered UPS’s claim that the Board exceeded its authority by reversing its own disability end-date.
  • Lyons v. Del. Liquor Comm'n (quoted in Henry v. Dep't of Lab.) reinforced the idea that the filing of an agency decision creates no “vested right” immune from correction—undercutting UPS’s reliance interest in the Board’s initial disability finding.
  • Moynihan v. City of Seaford supported the broader administrative-law value judgment that agencies should be afforded an opportunity to correct their own errors.

4. Temporary total disability and treating-physician no-work orders

The disability issue turned on a well-established but frequently litigated rule: whether a claimant is “totally disabled” when a treating physician instructs the claimant not to work, even if the claimant might physically perform some tasks.

  • Gilliard-Belfast v. Wendy's Inc. was treated as controlling: a claimant who could only work by disobeying a treating physician’s order is totally disabled—at least temporarily—regardless of capabilities. The Board expressly acknowledged it had failed to apply this rule in its initial decision and corrected that legal error on clarification.
  • Delhaize Am., Inc. v. Baker was invoked by UPS as a narrowing gloss. The Court rejected UPS’s attempt to read Delhaize as allowing the Board’s factfinding to override an ongoing no-work order merely because the Board “decides” the claimant is not disabled. Instead, the Court treated Delhaize as consistent with (and not a limitation upon) the core Gilliard-Belfast principle.
  • Smith v. James Thompson & Co. was used to reinforce that Delhaize “strengthen[s], instead of narrow[ing],” the Gilliard-Belfast rule and that it applies broadly in workers’ compensation claims “whether the parties agree that the claimant is disabled or not.”

B. Legal Reasoning

1. “Misstatement” versus “alteration of the record”

UPS’s central rhetorical move was to reframe the Board’s resolution of conflicting deposition testimony as an impermissible “rewrite” of expert testimony. The Supreme Court rejected that characterization by re-centering the dispute in ordinary administrative factfinding:

  • The Board had a record containing both (a) scattered references by Dr. Eskander to “2/3/23” and timing language suggesting a 2023 injury, and (b) explicit deposition testimony tying all treatment and surgeries to the February 2022 work injury, alongside Smith’s live testimony denying any 2023 fall.
  • The Board reconciled the internal inconsistency by finding it “more likely than not” that the “2023” references were a simple error in the year. The Court treated that reconciliation as a permissible inference from the whole record, not an impermissible substitution of “intended” testimony.
  • Under Person-Gaines v. Pepco Holdings, Inc., the Board could credit Dr. Eskander over UPS’s expert, Dr. Rushton, and could accept or reject portions of expert testimony. The Court emphasized that this type of weighing—especially in a causation contest—sits at the core of the Board’s delegated function.

2. Cross-examination: opportunity matters

UPS argued it was denied the chance to cross-examine on “altered testimony.” The Court’s response was practical and procedural: the inconsistencies appeared in the deposition itself; UPS attended the deposition with counsel; UPS could have confronted the witness on the inconsistency; UPS did not. The Court thus treated the “denial” argument as foreclosed by the record of opportunity.

3. Reconsideration power and correction of legal error

The Board’s clarifying order did more than explain; it changed the outcome on disability duration. The Court upheld that change because:

  • Under Henry v. Dep't of Lab., the Board has inherent authority to reopen and reconsider until jurisdiction is lost.
  • The Board identified a discrete legal mistake—failure to apply the Gilliard-Belfast rule to the undisputed fact that the treating physician kept Smith out of work during recovery—and corrected it.
  • Lyons v. Del. Liquor Comm'n (via Henry) undercut any claim that UPS had a settled entitlement to the initial decision’s disability end-date.

4. Harmonizing Gilliard-Belfast and Delhaize

The opinion’s most doctrinally important clarification is interpretive: it rejects a reading of Delhaize that would let an initial Board determination terminate temporary total disability notwithstanding an ongoing treating-physician no-work order—especially where the Board later recognizes it decided under the wrong legal standard. By emphasizing Smith v. James Thompson & Co., the Court framed Delaware law as consistently protective of claimants who follow medical restrictions, preserving the policy rationale articulated in Gilliard-Belfast (avoiding an “untenable position” for injured workers forced to choose between compliance and benefits).

C. Impact

  • Workers’ compensation disability disputes: The decision reinforces that, in Delaware, a claimant generally remains temporarily totally disabled during a treating physician’s good-faith no-work restriction—limiting litigation strategies that argue “work capacity” in the abstract while a physician continues to bar work.
  • Agency practice and motion work: The Court’s approval of the Board’s “clarifying order” as a vehicle for correcting legal error signals that parties should take clarification/reconsideration motions seriously: they can change outcomes where the Board identifies a misapplication of controlling law.
  • Deposition strategy and record development: The cross-examination holding incentivizes parties to confront testimonial inconsistencies when they arise (especially in depositions used in lieu of live testimony). Failure to do so may blunt later “procedural fairness” arguments on appeal.
  • Appellate deference: By repeatedly grounding its holding in substantial-evidence review and expert-weighing discretion, the Court underscores the high hurdle for overturning IAB findings framed as credibility and inference decisions rather than pure legal questions.

4) Complex Concepts Simplified

  • “Substantial evidence”: Not “the most persuasive evidence,” but enough relevant evidence that a reasonable person could reach the same conclusion. If that threshold is met, appellate courts generally do not reweigh the evidence.
  • Temporary total disability: A workers’ compensation status reflecting that the claimant is temporarily unable (as a legal matter) to work. Under Delaware’s treating-physician rule, the status can hinge on medical restrictions, not merely on what tasks the claimant might physically be able to perform.
  • Causation in workers’ compensation: The claimant must show the work accident proximately caused the need for treatment. Here, that meant deciding whether the surgeries flowed from the 2022 fall or from a supposed 2023 intervening event.
  • “Alteration of the record” (as alleged) vs. “factfinding” (as applied): An agency cannot invent testimony. But it can interpret conflicting testimony, decide what is credible, and infer that an inconsistency is a mistake—especially when other record evidence supports that inference.
  • Agency reconsideration and “no vested right”: Until an agency loses jurisdiction, it may revisit decisions to correct errors. A party generally cannot claim a permanent entitlement to an erroneous agency ruling merely because it was issued first.

5) Conclusion

United Parcel Service v. Ashley A. Smith affirms two practical principles with significant doctrinal consequences in Delaware workers’ compensation law: (1) the IAB’s reconciliation of inconsistent expert testimony—when grounded in the full record—is classic factfinding reviewed for substantial evidence, not “record alteration”; and (2) the IAB may reopen and correct its own legal mistakes, including misapplication of the treating-physician no-work-order rule rooted in Gilliard-Belfast v. Wendy's Inc., with Delhaize Am., Inc. v. Baker read as reinforcing rather than narrowing that protection. The decision strengthens predictability for claimants who follow medical restrictions and confirms the Board’s authority to self-correct before jurisdiction ends.
