LaTourette v. Workers' Comp. Appeals Bd. (1998) 17 Cal.App.4th 644
Applicant has burden to prove reasonable probability of industrial causation
Applicant's testimony was found not credible, so burden was not met
From the decision · page 2"The applicant for workers' compensation benefits has the burden of establishing the
`reasonable probability of industrial causation'" (LaTourette v. Workers' Comp. Appeals Bd.
(1998) 17 Cal.App.4th 644, 650 [63 Cal.Comp.Cases 253] citing McAllister v. Workmen's Comp.
Appeals Bd. (1968) 69 Cal.2d 408, 413 [33 Cal.Comp.Cases 660]; Lab. Code, § 3202.5, 5705.)
Here, since his testimony was found not credible, applicant neither set forth a prima facie case, nor
carried his ultimate burden of proof.
Honeywell v. Workers' Comp. Appeals Bd. (Wagner) (2005) 35 Cal.4th 24
Presumption of compensability under Labor Code section 5402(b) arises only if claim form filed and liability not rejected within 90 days
No claim form was filed, so presumption did not arise
From the decision · page 3rejected within 90 days after the date the claim form is filed under Section 5401, the injury shall
be presumed compensable under this division. The presumption of this subdivision is rebuttable
only by evidence discovered subsequent to the 90-day period." In Honeywell v. Workers' Comp.
Appeals Bd. (Wagner) (2005) 35 Cal.4th 24 [70 Cal.Comp.Cases 97], the California Supreme
Court expressly held that, except where estoppel has been established, the 90-day period to accept
or deny liability runs from the date that an injured worker filed an actual claim form, not when
applicant reported his or her injury, or when the employer otherwise gained knowledge of injury.
"`A presumption is an assumption of fact that the law requires to be made from another fact or
group of facts found or otherwise established in the action.' ( Evid. Code, § 600, subd. (a), italics
added; State Compensation Ins. Fund v. Workers' Comp. Appeals Bd. (1995) 37 Cal. App. 4th 675,
682 [60 Cal.Comp.Cases 717].) As correctly articulated in Davis [v. Interim Healthcare (2000)
65 Cal.Comp.Cases 1039, 1043 (Appeals Bd. en banc)], `a presumption becomes operative at trial
when the basic facts giving rise to the presumption are established by the pleadings, by stipulation,
by judicial notice, or by evidence.'" (Gee v. Workers' Comp. Appeals Bd. (2002) 96 Cal.App.4th
1418, 1425 [67 Cal.Comp.Cases 236].)
