Background
Dominick DiStefano was a forklift operator at Oldcastle Infrastructure, Inc., a warehouse facility in Pennsylvania. At the end of his shift in January 2023, he brushed accumulated dust and debris from his jacket—dust being a natural byproduct of forklift operations in a warehouse. In doing so, he accidentally dislodged a heavy bolt from his jacket pocket. The bolt fell and struck his left leg over his pants without breaking the skin. What followed was severe: DiStefano developed septic arthritis, cellulitis, and osteomyelitis in his left ankle—serious infectious complications that required hospitalization, surgery, and months of treatment—leaving him temporarily totally disabled until at least January 2024. He filed a workers’ compensation claim petition.
Employer Oldcastle resisted on every possible ground. Its infectious disease expert, Dr. Silverman, acknowledged in his written report that the bolt strike was “likely responsible for the infectious complication” DiStefano suffered—but later testified during deposition that he “was told by the attorney that was what happened” and was “trying to piece that together” in the absence of complete medical records. Workers’ Compensation Judge (WCJ) Krass found DiStefano’s testimony credible, rejected both of Employer’s medical experts as not credible, and granted the Claim Petition for disability benefits through January 2024. The Workers’ Compensation Appeal Board (Board) affirmed without dissent.
The Court’s Holding
Judge Wolf, writing for the panel, affirmed the Board on all four of Employer’s arguments. First, on intentional self-infliction: Section 301(a) of the Workers’ Compensation Act provides that “no compensation shall be paid” when a worker’s injury is “intentionally self inflicted,” 77 P.S. § 431, with the burden on the employer. Oldcastle argued that the intentional act was brushing the jacket to dislodge dust, and the resulting bolt drop was therefore intentional. The court rejected the argument as meritless: DiStefano did not brush his jacket with the purpose of dropping a bolt on his leg, and there was no basis to infer he intended to injure himself. The court noted that the intentional self-infliction defense has historically been applied in cases involving suicide or attempted suicide—a fundamentally different category. An accidental consequence of a deliberate act is not itself an intentional act.
Second, on scope of employment, the court applied the three-part Slaugenhaupt test (from Workmen’s Comp. Appeal Bd. (Slaugenhaupt) v. U.S. Steel Corp., 376 A.2d 271 (Pa. Cmwlth. 1977)), finding all three prongs satisfied. Dusting off at the end of a workday directly responds to a workplace condition—dust and debris generated by forklift operations—and is a reasonable undertaking by a warehouse worker. The court distinguished Lewis v. Lehigh Asphalt Paving (Pa. Cmwlth. 2023), where a claimant tore his Achilles tendon stepping up into a work truck after clocking out: that injury had no connection to the physical conditions of the workplace, whereas here the very dust DiStefano was removing was a product of his employment. Third, on causation, the court deferred to the WCJ’s credibility determination. Dr. Silverman’s admission that he wrote his report based on what “the attorney told him” devastated Employer’s medical case; the WCJ was entitled to credit DiStefano’s treating physicians instead. Fourth, on duration, the court reaffirmed that a claimant’s credible testimony of continuing pain and incapacity—even without anatomical confirmation—can support a finding of continued disability beyond the date of the employer’s independent medical examination.
Key Takeaways
- Pennsylvania’s intentional self-infliction defense under Section 301(a) of the Workers’ Compensation Act requires proof that the claimant intended to injure himself; an accidental injury arising as an unintended consequence of an intentional act—such as dropping a bolt while brushing dust from clothing—does not satisfy this standard, which has historically been reserved for suicide and attempted suicide.
- Under the Slaugenhaupt three-part test, end-of-shift activities that directly respond to physical conditions created by employment—such as removing workplace dust—fall within the scope of employment even when the employee has finished performing job duties; the key distinction from Lewis is whether the activity responds to a workplace-generated condition.
- An employer’s medical expert who concedes during cross-examination that he wrote conclusions in his written report because an attorney told him to, rather than based on independent clinical judgment, will likely lose credibility with the WCJ; employers should ensure their experts form independent opinions before committing them to writing.
- A claimant’s credible testimony of continuing pain and inability to work is sufficient evidence of ongoing disability even without supporting anatomical findings, and WCJ credibility determinations on this point are essentially unreviewable on appeal.
Why It Matters
This decision addresses two recurring defense theories in Pennsylvania workers’ compensation litigation. The intentional self-infliction defense is occasionally invoked when employers can point to some voluntary act by the claimant that contributed to the accident. The court’s analysis makes clear that the defense is narrow—it applies to self-harm, not to accidents that result from otherwise innocent voluntary acts. Employers attempting to extend it to typical workplace mishaps will not succeed.
The causation discussion also carries a warning for practitioners who use expert witnesses in workers’ compensation proceedings. An expert who acknowledges that an attorney shaped the conclusions in the written report before the expert independently assessed the clinical picture may do more harm than good to the employer’s case. Experienced WCJs routinely probe the independence of expert opinions, and an admission of attorney influence is difficult to overcome on cross-examination. Medical experts should be provided with full records and asked to form their own opinions before any discussion of conclusions.
