What it is
Protz is the most consequential Pennsylvania workers' compensation decision of the modern era. At issue was Section 306(a.2) of the Workers' Compensation Act, which required injured workers receiving total-disability benefits to undergo an Impairment Rating Evaluation (IRE) once they had received benefits for 104 weeks. If the IRE rated the worker's impairment below a certain threshold (50%, later reduced to 35%), the worker's benefit status was converted from "total" to "partial" — and partial benefits are capped at 500 weeks, while total benefits can continue indefinitely.
The IRE was performed under "the most recent edition" of the American Medical Association's Guides to the Evaluation of Permanent Impairment. That phrase — "most recent edition" — was the constitutional problem. By incorporating whatever future edition the AMA happened to publish, the Legislature had effectively given a private organization the power to write the law. The Pennsylvania Supreme Court held in 2017 that this was an unconstitutional delegation of legislative authority and struck the entire IRE provision.
After Protz, IREs were unenforceable. The Legislature re-enacted the IRE process in Act 111 of 2018 (codified at 77 P.S. § 511.3) using a fixed AMA edition (the Sixth Edition, second printing) and a 35% impairment threshold. Litigation over Act 111's retroactive application and constitutionality has continued.
Where it comes from
- The decision: Protz v. Workers' Compensation Appeal Board (Derry Area School District), 161 A.3d 827 (Pa. 2017)
- Decided: June 20, 2017
- Vote: 6–1 (Justice Wecht authoring the majority opinion)
- Statute struck down: former § 306(a.2) of the Pennsylvania Workers' Compensation Act, 77 P.S. § 511.2
- Legislative response: Act 111 of 2018, codified at 77 P.S. § 511.3
The constitutional doctrine the Court applied is the non-delegation doctrine — derived from Article II, Section 1 of the Pennsylvania Constitution, which vests the legislative power in the General Assembly. The Legislature may delegate authority to administrative agencies and courts within constraints, but it cannot delegate the substantive content of law to a private body without supplying meaningful standards.
Who it applies to
Protz changed the legal landscape for any Pennsylvania worker:
| Status as of June 20, 2017 | Effect of Protz |
|---|---|
| Receiving total-disability benefits, never IRE'd | IRE process unavailable until Act 111; worker remained on total disability |
| Receiving partial-disability benefits because of a pre-Protz IRE | Modification could be challenged; many workers had benefits restored to total |
| Receiving partial benefits for unrelated reasons (e.g., return-to-work earnings reduction) | Not directly affected — Protz concerned IREs, not other modification grounds |
| Worker injured after Act 111's effective date (Oct. 24, 2018) | New IRE framework applies under Act 111 |
The post-Protz litigation generated substantial follow-on appellate work, including Whitfield v. WCAB (which addressed the burden of proof for reinstating total-disability benefits after a struck-down IRE) and continuing disputes over Act 111's application to injuries pre-dating its enactment.
What it means in practice
Scenario 1 — Pre-Protz IRE conversion. A school employee injured in 2010 had her benefits converted from total to partial in 2014 based on an IRE result of 24%. She had been receiving partial benefits for three years when Protz was decided. The decision invalidated the IRE that converted her status. After Protz, she filed a reinstatement petition to restore total-disability status, with the burden being to show her impairment continued to affect her earning power. Whitfield clarified that the petition was the proper vehicle and that the burden was on the worker.
Scenario 2 — Act 111 worker. A retail worker injured in 2020 has received total-disability benefits for two years. The insurer requests an IRE under Act 111. The IRE is conducted under the AMA Sixth Edition (the version specifically named in Act 111), and the worker's whole-person impairment is rated at 28%. Because that is below the 35% threshold, the insurer files a notice converting her status to partial. She remains entitled to wage-loss benefits, but those benefits are now capped at 500 weeks (about 9.6 years).
Scenario 3 — Specific-loss interaction. Protz did not affect specific-loss benefits — the schedule of fixed payments for amputations and certain functional losses. A worker who lost two fingers on the job is entitled to specific-loss benefits regardless of whether IREs are enforceable; the IRE process only affects modification of ongoing wage-loss benefits.
