Pennsylvania Supreme Court: Sole Proprietors Need Not Notify Insurers of Work Injuries Within 120 Days
The Pennsylvania Supreme Court issued a significant ruling for the workers’ compensation insurance industry, holding that a sole proprietor who is also the sole employee of his business is not required to notify his workers’ compensation insurer of a work-related injury within 120 days in order to receive benefits.
The decision in Erie Insurance Property & Casualty Company vs. David Heater resolves a contested question about the scope of notice obligations under Pennsylvania’s Workers’ Compensation Act and carries meaningful implications for how insurers structure coverage terms for sole proprietors.
The dispute arose from an injury sustained in September 2015 by David Heater, the sole owner and employee of a general contracting business. While working as a subcontractor on a roofing job, Heater allegedly fell from a ladder and fractured his neck, requiring immediate surgery. Heater maintained that he contacted his insurance agent in October 2015, while still hospitalized, to report the injury.
Erie Insurance, however, did not receive formal notice of the claim until February 2017, approximately 17 months after the incident. Erie denied the claim, citing among other grounds that the notice was untimely under Section 311 of the Pennsylvania Workers’ Compensation Act, which bars compensation if an employer does not receive notice of a work-related injury within 120 days.
Heater argued that, under the plain language of Section 311, an injured employee is required only to notify his “employer” of the injury. Because he was simultaneously the employee and the employer, he contended that he had instantaneous notice of his own injury, and that the Act’s definition of “employer” does not include insurance carriers. He maintained that grafting such a requirement onto the statute contradicted the legislature’s clear intent.
Erie countered that Section 311 is ambiguous as to who qualifies as the “employer” when the injured claimant and employer are the same individual. The insurer argued that in such circumstances, the 120-day notice requirement’s core purpose — protecting against stale claims and enabling timely investigation — can only be fulfilled if notification is provided directly to the insurer. Erie maintained that a contrary reading creates an unfair class of claimants who could delay reporting a claim indefinitely, leaving the insurer unable to investigate while critical evidence disappears.
The Pennsylvania Supreme Court rejected Erie’s ambiguity argument. It found that the Workers’ Compensation Act contains two distinct definitions of “employer” — a general definition that does not include insurers, and a broader definition expressly limited to a specific article of the Act governing claims procedures. Because the notice provision falls outside that article, the court concluded the general definition controls.
While acknowledging the insurer’s practical concerns, the court was unequivocal that such concerns “cannot override the plain language” of a statutory provision. The court further noted that even if the broader definition were applied, it would permit a claimant to notify either the employer or the insurer — not require both.
The court reversed the lower court’s ruling and remanded the matter for further proceedings, holding that Section 311 imposes no obligation on a sole proprietor-employee to separately notify the insurer within 120 days.
