California Labor Code § 5904

Determinative passage · p.4If a decision includes resolution of a "threshold" issue, then it is a "final" decision, whether or not all issues are resolved or there is an ultimate decision on the right to benefits. (Aldi v. Carr, McClellan, Ingersoll, Thompson & Horn (2006) 71 Cal.Comp.Cases 783, 784, fn. 2 (Appeals Board en banc).) Threshold issues include, but are not limited to, the following: injury arising out of and in the course of employment, jurisdiction, the existence of an employment relationship and statute of limitations issues. (See Capital Builders Hardware, Inc. v. Workers' Comp. Appeals Bd. (Gaona) (2016) 5 Cal.App.5th 658, 662 [81 Cal.Comp.Cases 1122].) Failure to timely petition for reconsideration of a final decision bars later challenge to the propriety of the decision before the WCAB or court of appeal. (See Lab. Code, § 5904.) Alternatively, non-final decisions may later be challenged by a petition for reconsideration once a final decision issues.

The WCJ's decision included threshold issues making it a final order subject to reconsideration.

Determinative passage · p.1If a decision includes resolution of a "threshold" issue, then it is a "final" decision, whether or not all issues are resolved or there is an ultimate decision on the right to benefits. (Aldi v. Carr, McClellan, Ingersoll, Thompson & Horn (2006) 71 Cal.Comp.Cases 783, 784, fn. 2 (Appeals Board en banc).) Threshold issues include, but are not limited to, the following: injury arising out of and in the course of employment, jurisdiction, the existence of an employment relationship and statute of limitations issues. (See Capital Builders Hardware, Inc. v. Workers' Comp. Appeals Bd. (Gaona) (2016) 5 Cal.App.5th 658, 662 [81 Cal.Comp.Cases 1122].) Failure to timely petition for reconsideration of a final decision bars later challenge to the propriety of the decision before the WCAB or court of appeal. (See Lab. Code, § 5904.) Alternatively, non-final decisions may later be challenged by a petition for reconsideration once a final decision issues.

Applied to explain finality of threshold issues and reconsideration procedure.

Determinative passage · p.1Defendant seeks reconsideration of the June 10, 2025 Findings and Award (F&A), wherein the workers' compensation administrative law judge (WCJ) found that applicant, while employed as a semi-truck driver/laborer on August 4, 2010, sustained industrial injury to his cervical spine, thoracic spine, lumbar spine, headaches, hearing loss, psyche, hypertension, high blood pressure, heart-left ventricular hypertrophy, chest pain, medication effects, sleep, dysphasia, failed spine surgery, and adjacent segment disease. The WCJ found in relevant part that pursuant to Labor Code1 section 5904, defendant may not raise for the first time a dispute as to the permanent total disability rate that was not raised at the time of trial or upon Petition for Reconsideration. The WCJ also determined that defendant failed in their burden of proof that there are sufficient grounds to set aside stipulation of the parties as to wages, more than five years after the date of injury. The WCJ awarded penalties pursuant to section 5814 and attorney fees pursuant to section 5814.5.

The Board held that defendant waived the right to dispute wages and disability rates by not raising them in prior petitions for reconsideration or trial.

Determinative passage · p.2II. If a decision includes resolution of a "threshold" issue, then it is a "final" decision, whether or not all issues are resolved or there is an ultimate decision on the right to benefits. (Aldi v. Carr, McClellan, Ingersoll, Thompson & Horn (2006) 71 Cal.Comp.Cases 783, 784, fn. 2 (Appeals Board en banc).) Threshold issues include, but are not limited to, the following: injury arising out of and in the course of employment, jurisdiction, the existence of an employment relationship and statute of limitations issues. (See Capital Builders Hardware, Inc. v. Workers' Comp. Appeals Bd.

The WCJ's decision included a threshold issue making it a final decision subject to reconsideration.

Determinative passage · p.3statute of limitations issues. (See Capital Builders Hardware, Inc. v. Workers' Comp. Appeals Bd. (Gaona) (2016) 5 Cal.App.5th 658, 662 [81 Cal.Comp.Cases 1122].) Failure to timely petition for reconsideration of a final decision bars later challenge to the propriety of the decision before the WCAB or court of appeal. (See Lab. Code, § 5904.) Alternatively, non-final decisions may later be challenged by a petition for reconsideration once a final decision issues.

Applied to bar late challenges to final decisions.

Determinative passage · p.3of and in the course of employment, jurisdiction, the existence of an employment relationship and statute of limitations issues. (See Capital Builders Hardware, Inc. v. Workers' Comp. Appeals Bd. (Gaona) (2016) 5 Cal.App.5th 658, 662 [81 Cal.Comp.Cases 1122].) Failure to timely petition for reconsideration of a final decision bars later challenge to the propriety of the decision before the WCAB or court of appeal. (See Lab. Code, § 5904.) Alternatively, non-final decisions may later be challenged by a petition for reconsideration once a final decision issues.

The decision included a threshold issue making it final and subject to reconsideration rather than removal.

Determinative passage · p.2Removal is an extraordinary remedy rarely exercised by the Appeals Board. (Cortez v. Workers' Comp. Appeals Bd. (2006) 136 Cal.App.4th 596, 599, fn. 5 [71 Cal.Comp.Cases 155]; Kleemann v. Workers' Comp. Appeals Bd. (2005) 127 Cal.App.4th 274, 280, fn. 2 [70 Cal.Comp.Cases 133].) The Appeals Board will grant removal only if the petitioner shows that significant prejudice or irreparable harm will result if removal is not granted. (Cal. Code Regs., tit. 8, § 10955(a); see also Cortez, supra; Kleemann, supra.) Also, the petitioner must demonstrate that reconsideration will not be an adequate remedy if a final decision adverse to the petitioner ultimately issues. (Cal. Code Regs., tit. 8, § 10955(a).) Here, based upon the WCJ's analysis of the merits of the petitioner's arguments, we are not persuaded that significant prejudice or irreparable harm will result if removal is denied and/or that reconsideration will not be an adequate remedy.

The Appeals Board applied this standard to deny the petition for reconsideration because the petitioner did not meet the criteria for removal.

Determinative passage · p.1Preliminarily, we observe that if a decision includes resolution of a "threshold" issue, then it is a "final" decision, whether or not all issues are resolved or there is an ultimate decision on the right to benefits. (Aldi v. Carr, McClellan, Ingersoll, Thompson & Horn (2006) 71 Cal.Comp.Cases 783, 784, fn. 2 (Appeals Board en banc).) Threshold issues include, but are not limited to, the following: injury arising out of and in the course of employment, jurisdiction, the existence of an employment relationship and statute of limitations issues. (See Capital Builders Hardware, Inc. v. Workers' Comp. Appeals Bd. (Gaona) (2016) 5 Cal.App.5th 658, 662 [81 Cal.Comp.Cases 1122].) Failure to timely petition for reconsideration of a final decision bars later challenge to the propriety of the decision before the WCAB or court of appeal. (See Lab. Code, § 5904.) Alternatively, non-final decisions may later be challenged by a petition for reconsideration once a final decision issues.

The Appeals Board noted this statute in its analysis of the finality of the WCJ's decision.
