Authorities as the decision cited them, with how this panel applied each one.
California Labor Code
Labor Code 3208.3(b)(1) requires actual events of employment to be the predominant cause of a psychiatric injury for compensability.
Applied to determine compensability of psychiatric injury.
From the decision · page 4Labor Code section 3208.3 requires that in order for a psychiatric injury to be
compensable "actual events of employment" must be the predominant cause of the injury. In
this case, the parties agreed that the only issue to be determined was whether or not the
circumstances and events causing the applicant's injury qualify as an "actual event of
employment".
California Comp. & Fire Co. v. Workmen's Comp. App. Bd. (Schick), 68 Cal.2d 157
Compensability requires that the injury arise out of and in the course of employment, with employment playing a positive role in the injury's development, not merely providing a stage.
Applied to assess the connection between employment and injury.
From the decision · page 5As stated in California Comp. & Fire Co. v. Workmen's Comp. App. Bd. (Schick), 68
Cal.2d 157, 160, citing Madin, supra, 46 Cal.2d 90: "In finding that t4e injury arose out of
the employment, this court held that a sufficient causal connection between the injury and
the employment is shown where the employment was a contributory cause of the injury, that
where the injury occurs on the employer's premises while the employee is in the course of
his employment the injury also arises out of the employment unless the connection is so
remote from the employment that it is not an incident thereof, and that an injury can arise out
of the employment even though the employer had no connection with or control over the
force which caused the injury. It was also held that an injury is compensable where the
employee is brought into a position of danger by the employment even though the risk could
not have been foreseen by the employer, and, finally, that reasonable doubts as to whether
an injury is compensable are to be resolved in favor of the employee." (State Compensation
Ins. Fund v. Workers' Comp. Appeals Bd. (1982) 133 Cal.App.3d 643, 655 [184 Cal.Rptr.
111].)
State Compensation Ins. Fund v. Workers' Comp. Appeals Bd. (1982) 133 Cal.App.3d 643
An injury caused by a third party with unknown or no motive occurring in the course of employment is compensable if there is some employment connection or contribution.
Applied to determine compensability of injury caused by third party.
From the decision · page 5The court concluded, if a third party assaults and injures the employee while in the
course of employment and the third party acted out of purely personal motives there is no
compensability. However, if the employee can show there was some employment connection
or contribution, i.e., an industrial cause of the injury so as to establish the arising-out-of
element, then there is compensability. Such cause need not be the sole cause and need only
be a contributing cause. Finally, if the third party's assault causing the injury occurs in the
course of employment and is committed for unknown motives or no motive at all, i.e., for
nonpersonal motives, the injury is compensable. (State Compensation Ins. Fund v. Workers'
Comp. Appeals Bd. (1982) 133 Cal.App.3d 643,655 [184 Cal.Rptr. 111].)
