For many years now, employers have been able to rely on the holdings on Brodie v. WCAB (2007) 40 Cal. 4th 1313 and Benson v. Workers’ Comp. Appeals Bd. (2009) 170 Cal.App.4th 1535, 75 Cal.Comp.Cases 113, 2009 Cal. Wrk. Comp. LEXIS 17 to ensure that non-industrial factors would be fully considered where permanent disability is awarded as consequence of industrial injury. Brodie, in particular, ruled that such apportionment would carry through even when disability was assigned due to aggravation and the compensable consequences of an injury.
In 2017, however, the case of Hikida v Workers’ Comp. Appeals Bd., (2017) 12 Cal.App.5th 1249 made its way up to the Second District Court of Appeals, and seems to challenge the manner in which apportionment is utilized in such cases.
