Hegglin v. Workmen's Comp. Appeals Bd. (1971) 4 Cal.3d 162
A medical opinion is not substantial evidence if it is based on facts no longer germane, inadequate medical histories or examinations, incorrect legal theories, or surmise, speculation, conjecture, or guess; it must set forth reasoning, not merely conclusions.
Dr. Vakili's report lacked explanation and substantial evidence on causation and cumulative injury, thus not substantial evidence.
From the decision · page 4Appeals Bd.
(1970) 1 Cal.3d 627, 635 [35 Cal.Comp.Cases 16].) A medical opinion is not substantial evidence
if it is based on facts no longer germane, on inadequate medical histories or examinations, on
incorrect legal theories, or on surmise, speculation, conjecture, or guess, and the medical opinion
must set forth the reasoning behind the physician's opinion, not merely his or her conclusions; a
mere legal conclusion does not furnish a basis for a finding. (Hegglin v. Workmen's Comp. Appeals
Bd. (1971) 4 Cal.3d 162 [36 Cal.Comp.Cases 93]; Granado v. Workers' Comp. Appeals Bd. (1970)
69 Cal.2d 399, [33 Cal.Comp.Cases 647]; Escobedo v. Marshalls (2005) 70 Cal.Comp.Cases 604
(Appeals Board en banc).)
Here, in his first two reports, Dr. Vakili repeatedly referred to the "7/10/2010 incident" as
the basis for applicant's injury claim. (e.g. see Def. Exh. C, pp. 5, 87, 96, and 100; Def. Exh. D,
pp. 3 § 5, and 13 § 15.) At no point did he address the cumulative injury claim.
Notwithstanding the WCJ's recommendation that the parties have applicant examined by
an agreed medical examiner (AME), they requested a supplemental report from Dr. Vakili. In his
Labor Code section 5952(d)
Any award, order, or decision of the Appeals Board must be supported by substantial evidence.
The Appeals Board found the medical evidence insufficient and defective, requiring further development of the record.
From the decision · page 4DISCUSSION
Labor Code section 5909 provides that a petition for reconsideration is deemed denied
unless the Appeals Board acts on the petition within 60 days of filing. (Lab. Code, § 5909.)
Section 5315 provides the Appeals Board with 60 days within which to confirm, adopt, modify or
set aside the findings, order, decision or award of a workers' compensation administrative law
judge. (Lab. Code, § 5315.)
On June 5, 2020, the State of California's Governor, Gavin Newsom, issued Executive
Order N-68-20, wherein he ordered that the deadlines in sections 5909 and 5315 shall be extended
for a period of 60 days.1 Pursuant to Executive Order N-68-20, the time within which the Appeals
Board must act was extended by 60 days. Therefore, this decision is timely.
It 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.
