Authorities as the decision cited them, with how this panel applied each one.
Labor Code section 5300
The WCAB has exclusive jurisdiction over workers' compensation disputes under Labor Code section 5300 and the California Constitution.
Applied to determine the scope of WCAB jurisdiction over the misappropriation claim.
From the decision · page 5Pursuant to Labor Code section 5300,1 the WCAB has exclusive jurisdiction to adjudicate
the "recovery of compensation, or concerning any right or liability arising out of or incidental
thereto" of injuries that "arise out of and in the course" of employment," and that "[c]ompensation
includes medical treatment, temporary disability indemnity, permanent disability indemnity, SJDB
vouchers, and death benefits... In other words, the WCAB maintains exclusive jurisdiction
pursuant to the California Constitution and section 5300 to adjudicate workers' compensation
disputes." (Dennis v. State of California (2020) 85 Cal.Comp.Cases 28 [2020 Cal. Wrk. Comp.
LEXIS 1] (Appeals Board en banc).) The Appeals Board has continuing jurisdiction over all its
orders, decisions, and awards made and entered. (Lab. Code, § 5803.) The Appeals Board may
rescind, alter, or amend any order, decision, or award, for good cause. (Lab. Code, § 5803.)
Labor Code sections 5803 and 5804
The WCAB may rescind, alter, or amend any order, decision, or award for good cause but not after five years from the date of injury except for enforcement purposes.
Applied to limit the WCAB's authority to alter the Compromise and Release after five years.
From the decision · page 5Pursuant to Labor Code section 5300,1 the WCAB has exclusive jurisdiction to adjudicate
the "recovery of compensation, or concerning any right or liability arising out of or incidental
thereto" of injuries that "arise out of and in the course" of employment," and that "[c]ompensation
includes medical treatment, temporary disability indemnity, permanent disability indemnity, SJDB
vouchers, and death benefits... In other words, the WCAB maintains exclusive jurisdiction
pursuant to the California Constitution and section 5300 to adjudicate workers' compensation
disputes." (Dennis v. State of California (2020) 85 Cal.Comp.Cases 28 [2020 Cal. Wrk. Comp.
LEXIS 1] (Appeals Board en banc).) The Appeals Board has continuing jurisdiction over all its
orders, decisions, and awards made and entered. (Lab. Code, § 5803.) The Appeals Board may
rescind, alter, or amend any order, decision, or award, for good cause. (Lab. Code, § 5803.)
Smith v. Workers' Comp. Appeals Bd. (1985) 168 Cal.App.3d 1160
An approved Compromise and Release is a final judgment with res judicata effect after five years, and may only be set aside for fraud or mistake.
Applied to conclude the finality of the Compromise and Release agreement.
From the decision · page 5However, section 5804 provides that "No award of compensation shall be rescinded,
altered, or amended after five years from the date of the injury." "An approved workers'
compensation compromise and release rests `upon a higher plane than a private contractual release;
it is a judgment, with "the same force and effect as an award made after a full hearing."'" (Smith
v. Workers' Comp. Appeals Bd. (1985) 168 Cal.App.3d 1160, 1169, quoting Johnson v. Workmen's
Comp. App. Bd. (1970) 2 Cal.3d 964, 973.) Consequently, after the five year period has expired,
the Order Approving Compromise and Release constitutes a final judgement with the full effect of
res judicata. (Smith v. Workers' Comp. Appeals Bd., supra, 168 Cal.App.3d at p. 1169.) Therefore,
after five years, an award may only be set aside on the showing of fraud or mistake. (Id.)
Barnes v. Workers' Comp. Appeals Bd. (2000) 23 Cal.4th 679
The WCAB's jurisdiction to enforce awards extends beyond the five-year limit for rescinding awards.
Applied to explain the WCAB's continuing jurisdiction to enforce awards but not to alter them after five years.
From the decision · page 6In contrast to the limitations imposed by the statute on the Appeals Board to set aside an
entire award, the Appeals Board continues to have jurisdiction after five years to enforce its
awards. (Barnes v. Workers' Comp. Appeals Bd. (2000) 23 Cal.4th 679, 687 [65 Cal.Comp.Cases
780].) That is, the WCAB's jurisdiction to enforce an award extends beyond section 5804's five-
year limitations period because an order ascertaining and fixing the exact amount of liability does
not rescind, alter or amend any prior award in violation of section 5804. (Id.) Consequently,
collateral changes may be made to an award so long as the merits of the basic decision determining
the worker's right to benefits are not altered, and the amount of benefits remains unchanged.

Industrial Acci. Com. (1958) 162 Cal.App.2d 761, 767.)
