- ADJ7376924 · 2026-05-28 · Riverside District Office§ 5908.5
Determinative passage · p.3First, section 4453(c)(4) is not written in the conjunctive, but rather in the alternative: "Where the employment is for less than 30 hours per week, or where for any reason the foregoing methods of arriving at the average weekly earnings cannot reasonably and fairly be applied..." (Lab. Code, § 4453(c)(4), italics added.) Therefore, the fact that respondent worked more than 30 hours per week is not dispositive of whether section 4453(c)(4) applies or does not apply. It may be that the Appeals Board did consider the second part of the first sentence of section 4453(c)(4) and still rejected its application; however, the Appeals Board failed to include any explanation of its consideration as required by section 5908.5. (Lab. Code, § 5908.5.)3

(Savercool) (1923) 191 Cal.724, 729 [10 I.A.C. 322]) and of "[throwing] the entire record open for review." (State Comp. Ins. Fund v. Industrial Acc. Com. (George) (1954) 125 Cal.App.2d 201, 203 [19 Cal.Comp.Cases 98].)

Determinative passage · p.11Section 5908.5 requires that the appeals board state the evidence relied upon and specify in detail the reasons for its decisions. (Lab. Code, § 5908.5.)

(Evans, supra, 68 Cal.2d 753, 755.)
The WCJ's opinion did not adequately analyze the evidence or reasons, requiring the Appeals Board to remand for further proceedings.
