On April 26, 2017, the California Third District Court of Appeal stated that genetic causes, including inherited predispositions, may be considered in medical evaluations to apportion the employer’s share of liability for work-related injuries.  This builds further upon the current standard for workers’ compensation injuries in which employers must compensate workers only for the portion of a disability caused by a work-related injury.

The case was City of Jackson v. Workers’ Compensation Appeals Board and Christopher Rice.  Rice worked as a police officer for City of Jackson and suffered a neck injury that required surgery.  A qualified medical examiner (“QME”) evaluated Rice both before and after his surgery.  Due to newly published studies in the medical field, the QME maintained the same diagnoses but reapportioned Rice’s disability to the following ratio: 17% caused by employment with the City, 17% caused by previous employment, 17% caused by personal activities, and 49% caused by his personal history, inclusive of genetic issues.  The Workers’ Compensation Appeals Board (“WCAB”) disagreed, stating that causation could not be assigned to genetics because genetics is an “impermissible immutable factor.”The appeals court pointed to inconsistencies in the WCAB’s past rulings, with specific regard to a 2008 case in which the WCAB had approved a QME’s findings of a pre-existing genetic predisposition contributing to the worker’s overall disability level.  The court found that the QME’s 17% apportionment of Rice’s injury based on employment activities with the City was correct, and that this determination was based on substantial medical evidence.

The court therefore remanded the case to the WCAB to issue a decision based on the QME’s findings.
