Verdin: Corroborated Testimony and a Reasoned QME Opinion Supported Two Industrial Injuries

By Aneeta Mishra and Timothy Chan

A construction laborer suffered two head-and-body incidents while working at a homeowner's project. The WCJ found both the contractor and homeowner were employers, found industrial injuries, and awarded future medical care while deferring remaining issues for record development.

Industrial causation requires reasonable probability

The applicant did not have to prove causation with scientific certainty. The mechanism of injury, testimony, treatment history, examination, and diagnostic material supported the QME's causation opinion.

Credibility arguments did not erase corroboration

The employer's own testimony substantially corroborated the occurrence of the incidents. The WCAB evaluated inconsistencies within the complete evidentiary record rather than treating them as automatic defeat.

A medical opinion must explain its basis

The QME connected the claimed mechanisms to the examined conditions and relied on medical records, history, testing, and examination. That reasoned foundation met the substantial-evidence standard for the findings reviewed.

Uninsured employment findings have practical consequences

The finding that the homeowner and contractor were employers placed the injuries within the compensation system despite the lack of insurance and preserved the role of the Uninsured Employers Benefits Trust Fund.

Key takeaways

• Develop testimony from every person who observed the work and incident.
• Give the medical evaluator a complete and accurate history and record set.
• Connect each claimed body part to a reasoned medical-causation analysis.
• Resolve employment and insurance status early when multiple hirers are involved.
