Substantial evidence must support any award, order, or decision of the Appeals Board.
Dr. Hyman's report based on adequate history, examination, and reasoning constitutes substantial evidence; Dr. Nogales' report does not.
From the decision · page 3It is well established that any award, order, or decision of the Appeals Board must be
supported by substantial evidence. (Lab. Code, § 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. Appeals Bd.
(1970) 3 Cal.3d 312, 317 [35 Cal.Comp.Cases 500]; LeVesque v. Workmen's Comp. Appeals Bd.
(1970) 1 Cal.3d 627, 635 [35 Cal.Comp.Cases 16].) When a physician's report is based on an
adequate history and examination, is not speculative, and sets forth the reasoning behind the
physician's opinion, not merely his or her conclusions, the report constitutes substantial evidence.

Appeals Board has discretionary authority to develop the record when substantial evidence is lacking on a threshold issue.
Record lacks substantial evidence on psychiatric injury; Appeals Board defers issue for further proceedings with psychiatry/psychology QME or AME evaluation.
From the decision · page 5Therefore, we agree with the WCJ that the report from Dr. Nogales is not substantial
evidence regarding applicant's psychiatric injury claim. However, the Appeals Board has the
discretionary authority to develop the record when the record does not contain substantial evidence
pertaining to a threshold issue, or when it is necessary in order to fully adjudicate the issues. (Lab.
Code § 5701, 5906; Tyler v. Workers' Comp. Appeals Bd. (1997) 56 Cal.App.4th 389 [62
Cal.Comp.Cases 924]; see McClune v. Workers' Comp. Appeals Bd. (1998) 62 Cal.App.4th 1117
[63 Cal.Comp.Cases 261].) The Appeals Board has a constitutional mandate to "ensure substantial
justice in all cases" and "may not leave matters undeveloped where it is clear that additional
discovery is needed." (Kuykendall v. Workers' Comp. Appeals Bd.
