468 P.3d 110
Haw.2020Background
- Jay D. Cadiz worked as a meatcutter at Times Supermarket in Kāne‘ohe for ~4 years (starting 2004); he was healthy before transfer and developed chronic symptoms (respiratory, headaches, dizziness, cognitive complaints) while employed.
- The meat department was found to be moldy and water-damaged; Cadiz’s clinic-ordered urine mycotoxin panel (Oct. 2011) showed elevated ochratoxin and trichothecene.
- Employer-ordered IMEs (Drs. Cupo, Likewise, Arora) offered alternative, non–mold explanations and did not meaningfully address the laboratory mycotoxin results.
- LIRAB credited the employer’s IMEs, excluded or limited portions of claimant’s expert evidence in the first hearing, and denied compensability; the ICA affirmed.
- The Hawai‘i Supreme Court vacated the ICA/LIRAB rulings, holding the employer failed to meet its burden of production because the IMEs did not rebut the objective mycotoxin evidence; court remanded with instruction that the injury-by-disease is compensable.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether employer produced substantial evidence to rebut the statutory presumption that the injury was work‑connected | Cadiz: objective mycotoxin labs + moldy workplace make work‑connection reasonably appear; presumption stands | QSI: three IME reports offered specific alternative medical explanations disproving work‑connection | Held: Employer failed burden of production; IMEs did not rebut lab evidence; presumption remains and claim is compensable |
| Whether IME opinions that symptoms are "medically plausibly explainable" by non‑work causes suffice as substantial evidence | Cadiz: plausible alternatives are insufficient; employer must disprove causal link | QSI: IMEs provided specific, plausible non‑mold causes (allergy, anxiety, GERD, low toxic risk) | Held: Plausible alternative explanations alone do not disprove work‑connection; such speculation is not substantial evidence to overcome presumption |
| Whether the IMEs adequately addressed the verified mycotoxin levels in claimant’s body | Cadiz: IMEs largely ignored or failed to meaningfully analyze the lab results | QSI: IME authors opined mold exposure unlikely to cause toxicity here (spore counts, mold species) | Held: IMEs failed to directly confront or refute the laboratory mycotoxin findings; that omission defeats a finding of substantial evidence |
| Effect of LIRAB’s evidentiary rulings (exclusion/admission of Dr. Hope) on the outcome | Cadiz: exclusion prejudiced his case by removing expert context for lab results; live testimony later admitted in Cadiz II | QSI: board has discretion to exclude untimely evidence | Held: Supreme Court based decision on lab evidence and employer’s failure to rebut it and therefore did not need to resolve all procedural questions; noted LIRAB failed to resolve reasonable doubts in claimant’s favor and remanded for proceedings consistent with opinion |
