Delaware Supreme Court Affirms Denial of Workers' Compensation Claim Based on Witness Credibility
2026 Del. LEXIS 286 * | 2026 LX 491806 | 2026 WL 2321783
September 22, 2026
The Delaware Supreme Court affirmed a Superior Court decision upholding the Industrial Accident Board's denial of a petition for workers' compensation benefits. The Court ruled that the Board's decision was supported by substantial evidence, deferring to the Board's findings regarding witness credibility and medical expert testimony.
Prince Parker worked for The Borsello Companies, Inc., where his duties included operating a forklift and mixing mortar. He alleged a lumbar spine injury on February 19, 2024 and reported his injury immediately, although the company denied receiving any such report.
It was not until ten days later, on February 29, 2024, Parker sent a text message to a project manager stating his work activities were "screwing [his] back up." Parker was advised to contact the company president. There was no evidence he did and continued his normal work activities.
In mid-March 2024, Parker was terminated for insubordination. On March 21, 2024, over a month after the alleged work incident, Parker went to the emergency room for back pain. Emergency room records reflected Parker reported his back pain had been ongoing for over a year, denied any recent trauma, and stated he had not followed up on a prior referral to see a specialist.
After the employer denied the claim for benefits, Parker filed a petition with the Board seeking wage loss benefits and payment of outstanding medical bills. The Board heard conflicting medical expert testimony and testimony from the claimant and employer witnesses. The Board, after hearing the testimony, denied Parker's petition, finding that he failed to establish a compensable injury. They did not find Parker’s testimony credible that he suffered a work injury. The Superior Court subsequently affirmed the Board's decision.
On appeal, the Delaware Supreme Court addressed and rejected several challenges raised by Parker. Most importantly, the court emphasized that under Delaware law, the Board has exclusive responsibility for weighing evidence, determining witness credibility, and resolving conflicts in testimony. The court deferred to the Board's decision to find Parker’s testimony not credible due to his ten-day delay in reporting back pain, his failure to seek immediate medical treatment, and his emergency room statements denying recent trauma. Since the claimant’s expert relied on the information from Parker, his opinion was discredited. The Board properly found the defense expert’s opinion more persuasive.
It is extremely important to ascertain all information related to when the alleged injury occurred, how it occurred and determine if the injured worker is providing the same version of events to the medical providers and the claims handler. Cases turn on credibility and the Board is tasked with making those findings.
