Determinative passage · p.5(Wright v. Beverly Fabrics (2002) 95 Cal.App.4th 346 [67 Cal.Comp.Cases 51].) Section 3600(a) provides for liability for injuries sustained “arising out of and in the course of the employment.” Section 3600(a)(2) requires as a condition of compensation that “at the time of the injury, the employee is performing service growing out of and incidental to his or her employment and is acting within the course of his or her employment.” (Lab. Code, § 3600(a)(2).) An employer is liable for workers’ compensation benefits “without regard to negligence.” (Lab. Code, § 3600(a).) An employee bears the burden of proving injury AOE/COE by a preponderance of the evidence. (South Coast Framing, Inc. v. Workers' Comp. Appeals Bd. (Clark) (2015) 61 Cal.4th 291, 297-298, 302 [80 Cal.Comp.Cases 489]; Lab. Code, §§ 3600(a), 3202.5.) For the purpose of meeting the causation requirement in a workers’ compensation injury claim, it is sufficient if the work is a contributing cause of the injury. (South Coast Framing, supra, at pp. 298-299.) “The applicant in a workers’ compensation proceeding has the burden of proving industrial causation by a ‘reasonable probability.’ (citation) That burden manifestly does not require the applicant to prove causation by scientific certainty.” (Rosas v. Workers’ Comp. Appeals Bd. (1993) 16 Cal.App.4th 1692, 1700-1701 [58 Cal.Comp.Cases 313].)
The Board applied these standards to find the applicant met the burden of proving injury AOE/COE based on credible testimony and medical evidence.

Determinative passage · p.4To be compensable, an injury must arise out of and occur in the course of employment. (Lab. Code, § 3600.) The employee bears the burden of proving injury AOE/COE by a preponderance of the evidence. (South Coast Framing v. Workers’ Comp. Appeals Bd. (Clark) (2015) 61 Cal.4th 291, 297-298, 302 [80 Cal.Comp.Cases 489]; Lab. Code, §§ 3600(a), 3202.5, 5705.) Whether an employee’s injury arose out of and in the course of employment is generally a question of fact to be determined in light of the particular circumstances of the case. (Wright v. Beverly Fabrics (2002) 95 Cal.App.4th 346, 353 [67 Cal.Comp.Cases 51].) “That burden manifestly does not require the applicant to prove causation by scientific certainty.” (Rosas v. Worker’s Comp. Appeals Bd. (1993) 16 Cal.App.4th 1692, 1701 [58 Cal.Comp.Cases 313].) It is well established that decisions by the Appeals Board must be supported by substantial evidence. (Lab. Code, §§ 5903, 5952(d); Lamb v. Workmen’s Comp. Appeals Bd. (1974) 11 Cal.3d 274, 281 [39 Cal.Comp.Cases 310]; Garza v. Workmen’s Comp.

Determinative passage · p.4When an injured worker claims a physical injury, the injured worker has the initial burden of proving industrial causation by showing the employment was a contributing cause. (South Coast Framing v. Workers’ Comp. Appeals Bd. (Clark) (2015) 61 Cal.4th 291, 297-298, 302; § 5705.) The injured worker must prove by a preponderance of the evidence that an injury arises out of and occurs in the course of employment (Labor Code §§ 3202.5, 3600(a)). “The requirement of Labor Code section 3600 is twofold. On the one hand, the injury must occur in the course of the employment. This concept ordinarily refers to the time, place, and circumstances under which the injury occurs. On the other hand, the statute requires that an injury arise out of the employment. It has long been settled that for an injury to arise out of the employment it must occur by reason of a condition or incident of the employment. That is, the employment and the injury must be linked in some causal fashion. *** The statutory proximate cause language [of section 3600] has been held to be less restrictive than that used in tort law, because of the statutory policy set forth in the Labor Code favoring awards of employee benefits.
The Board applied this standard to find that the decedent's lung cancer and death were industrially caused by employment exposure to diesel exhaust as a co-carcinogen.

Determinative passage · p.6III. We now turn to the issue of whether the post-termination defense under section 3600(a)(10) applies. The WCJ found applicant’s claim to be barred by section 3600(a)(10), which provides in pertinent part that: (10) Except for psychiatric injuries governed by subdivision (e) of Section 3208.3, where the claim for compensation is filed after notice of termination or layoff, including voluntary layoff, and the claim is for an injury occurring prior to the time of notice of termination or layoff, no compensation shall be paid unless the employee demonstrates by a preponderance of the evidence that one or more of the following conditions apply:

Determinative passage · p.11I deferred the issue of earnings and set the matter for status conference regarding the earnings issue; therefore, I did not rule on the issue of earnings. As such, the rate of permanent disability indemnity and attorney’s fees were not yet calculated or awarded. 3. Contentions on reconsideration. In its petition for reconsideration, defendant contends this WCJ erred in relying on the reporting of QME Dr. Fields Brewer regarding compensability of the cervical spine and left shoulder, and WPI opinions. Defendant contends that the WPIs assigned by the QME are not substantial evidence and should not be utilized in determining applicant’s permanent disability. DISCUSSION 1. Compensability of cervical spine and left shoulder Applicant bears the burden of proving injury AOE/COE by a preponderance of the evidence. (South Coast Framing v. Workers’ Comp. Appeals Bd. (Clark) (2015) 61 Cal.4th 291, 297-298, 302; Lab. Code, §§ 3600(a); 3202.5.) It is sufficient to show that work was a contributing cause of the injury.

Determinative passage · p.5We highlight several legal principles that may be relevant to our review of this matter. California has a no-fault workers’ compensation system. With few exceptions, all California employers are liable for the compensation provided by the system to employees injured or disabled in the course of and arising out of their employment, “irrespective of the fault of either party.” (Cal. Const., art. XIV, § 4.) The protective goal of California’s no-fault workers’ compensation legislation is manifested “by defining ‘employment’ broadly in terms of ‘service to an employer’ and by including a general presumption that any person ‘in service to another’ is a covered ‘employee.’” (Lab. Code, §§ 3351, 5705(a); S. G. Borello & Sons, Inc. v. Department of Industrial Relations (1989) 48 Cal.3d 341, 354 [54 Cal.Comp.Cases 80.) Notwithstanding the above, Labor Code section 3600 only imposes liability on an employer for workers’ compensation benefits if an employee sustains an injury arising out of and occurring in the course of employment (AOE/COE). An employer is liable for workers’ compensation benefits, where, at the time of the injury, an employee is “performing service growing out of and incidental to his or her employment and is acting within the course of employment.” (Lab.

Determinative passage · p.8III. We highlight the following legal principles that may be relevant to our review of this matter: An employee bears the burden of proving injury AOE/COE by a preponderance of the evidence.
