Pennsylvania's highest court just stripped workers' compensation insurers of a key defense when sole proprietors delay reporting workplace injuries.
In a unanimous decision handed down on March 26, 2026, the Supreme Court of Pennsylvania ruled that a sole proprietor who is both the owner and only employee of a business does not have to notify his workers' compensation insurer of a work injury within 120 days to remain eligible for benefits. The ruling reverses a Commonwealth Court decision that had sided with the insurer and effectively removes the statutory notice forfeiture defense for an entire class of policyholders.
The case stems from a 2015 incident involving David Heater, who ran a one-man general contracting business under the name "David W. Heater." Erie Insurance Property & Casualty Company provided his workers' compensation coverage. On September 28, 2015, Heater was performing roof repairs as a subcontractor when he allegedly fell from a ladder and fractured his neck, requiring immediate surgery.
Erie maintained it did not learn of Heater's injury until February 2017 – roughly 17 months later. The insurer denied the claim, arguing that Heater had not been injured on the job and contending he had actually hurt himself attempting a backflip during a break. Interestingly, Erie did not initially cite the 120-day notice requirement as grounds for its denial. Instead, it pointed to statutory exemptions for sole proprietors.
Heater filed a formal claim petition in September 2018. The case wound through multiple levels of adjudication. A workers' compensation judge ruled against Heater on the notice issue, finding that he had failed to notify Erie within the statutory window. The Workers' Compensation Appeal Board reversed that decision, reasoning that because Heater was his own employer, his employer's knowledge of the injury was immediate. The Commonwealth Court then reversed the Board, holding that in the sole-proprietor context, the term "employer" in the notice statute should be read to include the insurer.
The Supreme Court disagreed. Writing for the full seven-member bench, Chief Justice Todd focused squarely on the text of the statute. Section 311 of the Workers' Compensation Act requires injured employees to give notice to their "employer" within 120 days. The Act defines "employer" in two places. Section 103, which applies across the entire Act, defines the term to include natural persons, partnerships, and corporations – but not insurers. Section 401, which sits within Article IV on procedure, broadens the definition to include insurers, but uses the phrase "when used in this article," expressly limiting that broader definition to Article IV.
Since Section 311 falls outside Article IV, the Court found that the general definition in Section 103 controls. Under that definition, an insurer is not an "employer," and no notice to the insurer is required. The Court said the Commonwealth Court had found ambiguity where none existed and should not have turned to statutory construction tools to override what the text plainly states.
The Court went one step further, noting that even under the broader Section 401 definition, the statute uses the word "or" – meaning an injured worker satisfies the notice requirement by notifying his employer or his insurer, not both. Heater, as his own employer, already had knowledge of his own injury – which the Court suggested would seemingly satisfy the notice requirement even under the broader definition.
The decision carries practical weight for workers' compensation insurers, particularly those writing policies for sole proprietors and one-person sole proprietorships. The ruling means insurers cannot rely on Section 311's forfeiture provision to deny late-reported claims from this class of policyholders. The Court acknowledged the concern that sole proprietors could sit on claims indefinitely, controlling the timeline of investigation to the insurer's disadvantage, but held that this worry cannot override what the statute actually says. The Court left it to the legislature to address any perceived gaps in the law.
There is, however, a thread in the opinion that points to a practical workaround for insurers. Earlier Commonwealth Court decisions in this line of cases had noted that insurers can protect themselves contractually by writing mandatory prompt-notification provisions directly into their workers' compensation policies. The rights and duties between an employer and a workers' compensation carrier, those courts observed, are contractual matters to be set out in the policy rather than imposed by the legislature. In other words, what the statute does not require, the policy still can.
For insurers covering sole proprietors in Pennsylvania, the message from this ruling is straightforward. The statutory notice defense is off the table for this category of claimant. Carriers that want protection against delayed reporting will need to build that protection into the policy itself.
