520 P.3d 168
Ariz.2022Background
- Timothy Matthews, a Tucson police officer with preexisting PTSD, witnessed and later inspected a June 2018 domestic-violence barricade in which an armed suspect ultimately died; he subsequently experienced worsening PTSD symptoms and sought treatment.
- Matthews filed a workers’ compensation claim alleging the June 2018 incident substantially exacerbated his preexisting PTSD; the City’s insurer denied the claim.
- The ALJ found the incident was not an "unexpected, unusual or extraordinary stress" under A.R.S. § 23-1043.01(B) and denied compensation; the ALJ also declined to treat Matthews’ prior incidents as a gradual-injury claim because none was filed as such.
- The court of appeals affirmed in a divided opinion; Matthews sought review in the Arizona Supreme Court, raising constitutional challenges to § 23-1043.01(B).
- The Arizona Supreme Court held § 23-1043.01(B) does not violate Article 18, § 8 of the Arizona Constitution or equal protection and affirmed the ALJ’s denial on the facts (vacating limited portions of the court of appeals opinion).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Article 18 § 8 of the Arizona Constitution covers mental (stress-induced) injuries | Matthews: § 8’s "injury...from any accident" includes mental injuries from workplace stress | City: original public meaning limited "injury" and "accident" to physical, unexpected events; legislature may define/expand compensation | Majority: original meaning did not encompass stress-only mental illnesses; legislature permissibly expanded coverage (statute valid). Dissent: § 8 does include mental injuries. |
| Whether § 23-1043.01(B) unlawfully alters legal causation (Grammatico) by adding "unexpected, unusual or extraordinary" requirement | Matthews: statute imposes an extra proof burden that redefines constitutional legal causation | City: statute codifies a permissible limitation/definition and aligns with constitutional mandate | Held: statute does not impermissibly alter Article 18 § 8; it supplements/clarifies coverage rather than contracting constitutional rights. |
| Equal protection challenge | Matthews: statute treats mental-injury claimants worse by requiring a higher showing | City: statute treats the class uniformly and addresses a real evidentiary/causation difference | Held: statute passes equal protection review; classification justified by legitimate differences and evidentiary concerns. |
| Application to Matthews’ claim (fact question) | Matthews: June 2018 event was the "straw that broke the camel’s back" and substantially contributed to his PTSD | City: incident was a foreseeable, ordinary hazard of police work; not unexpected or extraordinary | Held: ALJ and Court: incident was not "unexpected, unusual or extraordinary"; claim denied. |
