- ADJ18236958 · 2026-06-22 · Lodi District Office§ 5900
Determinative passage · p.4A. A petition for reconsideration may properly be taken only from a "final" order, decision, or award. (Lab. Code, § 5900(a), 5902, 5903.) A "final" order has been defined as one that either "determines any substantive right or liability of those involved in the case" (Rymer v. Hagler (1989) 211 Cal.App.3d 1171, 1180; Safeway Stores, Inc. v. Workers' Comp. Appeals Bd. (Pointer) (1980) 104 Cal.App.3d 528, 534-535 [45 Cal.Comp.Cases 410]; Kaiser Foundation Hospitals v. Workers' Comp. Appeals Bd. (Kramer) (1978) 82 Cal.App.3d 39, 45 [43 Cal.Comp.Cases 661]) or determines a "threshold" issue that is fundamental to the claim for benefits. (Maranian v. Workers' Comp. Appeals Bd. (2000) 81 Cal.App.4th 1068, 1070, 1075 [65 Cal.Comp.Cases 650].) Interlocutory procedural or evidentiary decisions, entered in the midst of the workers' compensation proceedings, are not considered "final" orders. (Id. at p. 1075.) Such interlocutory decisions include, but are not limited to, pre-trial orders regarding evidence, discovery, trial setting, venue, or similar issues.
Interlocutory minutes of hearing and Notice of Intent to Impose Sanctions are not final orders subject to reconsideration.

Determinative passage · p.8Here, the failure of applicant to timely appeal the order finding him to be a vexatious litigant within the stated time limits precludes the Appeals Board from considering the issue of the PWCJ's findings declaring him a vexatious litigant.
The Appeals Board applied the time limits to deny the request to vacate the vexatious litigant order due to untimely appeal.

Determinative passage · p.6II. A petition for reconsideration may properly be taken only from a "final" order, decision, or award. (Lab. Code, § 5900(a), 5902, 5903.) A "final" order has been defined as one that either "determines any substantive right or liability of those involved in the case" (Rymer v. Hagler (1989) 211 Cal.App.3d 1171, 1180; Safeway Stores, Inc. v. Workers' Comp. Appeals Bd. (Pointer) (1980) 104 Cal.App.3d 528, 534-535 [45 Cal.Comp.Cases 410]; Kaiser Foundation Hospitals v. Workers' Comp. Appeals Bd. (Kramer) (1978) 82 Cal.App.3d 39, 45 [43 Cal.Comp.Cases 661]) or determines a "threshold" issue that is fundamental to the claim for benefits. (Maranian v. Workers' Comp. Appeals Bd. (2000) 81 Cal.App.4th 1068, 1070, 1075 [65 Cal.Comp.Cases 650].) Interlocutory procedural or evidentiary decisions, entered in the midst of the workers' compensation proceedings, are not considered "final" orders. (Maranian, supra, at p. 1075 ["interim orders, which do not decide a threshold issue, such as intermediate procedural or evidentiary decisions, are not `final'..."]; Rymer, supra, at p. 1180 ["[t]he term [`final'] does not include intermediate procedural orders or discovery orders"]; Kramer, supra, at p. 45 ["[t]he term

Determinative passage · p.7Turning now to the merits of the Petitions, we remind the parties that there are 25 days allowed within which to file a petition for reconsideration from a "final" decision that has been served by mail upon an address in California. (Lab. Code, § 5900(a), 5903; Cal. Code Regs., tit. 8, § 10605(a)(1).) This time limit is extended to the next business day if the last day for filing falls on a weekend or holiday. (Cal. Code Regs., tit. 8, § 10600.) To be considered timely, however, a petition for reconsideration must be filed with (i.e., received by) the WCAB within the time allowed; proof that the petition was mailed (posted) within that period is insufficient. (Cal. Code Regs., tit. 8, § 10940(a), 10615(b).) This time limit is jurisdictional and, therefore, the Appeals Board has no authority to consider or act upon an untimely petition for reconsideration. (Maranian v. Workers' Comp. Appeals Bd. (2000) 81 Cal.App.4th 1068, 1076 [65 Cal.Comp.Cases 650]; Rymer v. Hagler (1989) 211 Cal.App.3d 1171, 1182; Scott v. Workers' Comp. Appeals Bd. (1981) 122 Cal.App.3d 979, 984 [46 Cal.Comp.Cases 1008]; U.S. Pipe & Foundry Co. v. Industrial Acc. Com. (Hinojoza) (1962) 201 Cal.App.2d 545, 549 [27 Cal.Comp.Cases 73].)
Applied to dismiss defendant's untimely petition for reconsideration of the February 1, 2021 Findings.

Determinative passage · p.4II. A petition for reconsideration may properly be taken only from a "final" order, decision, or award. (Lab. Code, § 5900(a), 5902, 5903.) A "final" order has been defined as one that either "determines any substantive right or liability of those involved in the case" (Rymer v. Hagler (1989) 211 Cal.App.3d 1171, 1180; Safeway Stores, Inc. v. Workers' Comp. Appeals Bd. (Pointer) (1980) 104 Cal.App.3d 528, 534-535 [45 Cal.Comp.Cases 410]; Kaiser Foundation Hospitals v. Workers' Comp. Appeals Bd. (Kramer) (1978) 82 Cal.App.3d 39, 45 [43 Cal.Comp.Cases 661]) or determines a "threshold" issue that is fundamental to the claim for benefits. (Maranian v. Workers' Comp. Appeals Bd. (2000) 81 Cal.App.4th 1068, 1070, 1075 [65 Cal.Comp.Cases 650].) 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].) Interlocutory procedural or evidentiary decisions, entered in the midst of the workers' compensation proceedings, are not considered "final" orders. (Id. at p.
The WCJ's orders regarding admissibility of evidence and QME review were interlocutory and not final, so reconsideration was dismissed.

Determinative passage · p.2I. We first address the timeliness of defendant's petition. There are 25 days allowed within which to file a petition for reconsideration from a "final" decision that has been served by mail upon an address in California. (Lab. Code, § 5900(a), 5903; Cal. Code Regs., tit. 8, § 10605(a)(1).) This time limit is extended to the next business day if the last day for filing falls on a weekend or holiday. (Cal. Code Regs., tit. 8, § 10600.) To be timely, however, a petition for reconsideration must be filed with (i.e., received by) the WCAB within the time allowed; proof that the petition was mailed (posted) within that period is insufficient. (Cal. Code Regs., tit. 8, § 10940(a), 10615(b).) This time limit is jurisdictional and, therefore, the Appeals Board has no authority to consider or act upon an untimely petition for reconsideration. (Maranian v. Workers' Comp. Appeals Bd. (2000) 81 Cal.App.4th 1068, 1076 [65 Cal.Comp.Cases 650]; Rymer v. Hagler (1989) 211 Cal.App.3d 1171, 1182; Scott v. Workers' Comp. Appeals Bd. (1981) 122 Cal.App.3d 979, 984 [46 Cal.Comp.Cases 1008]; U.S. Pipe & Foundry Co. v.
The defendant's petition was initially filed with the wrong case number but was accepted as timely after correction.

A "final" order has been defined as one that either "determines any substantive right or liability of those involved in the case" (Rymer v.

Applied to dismiss the petition for reconsideration as the order continuing a status conference is not a final order.

Determinative passage · p.4This time limit is jurisdictional, and, therefore, the Appeals Board has no authority to consider or act upon an untimely petition for reconsideration. (Maranian v. Workers' Comp. Appeals Bd. (2000) 81 Cal.App.4th 1068, 1076 [65 Cal.Comp.Cases 650, 656]; Rymer v. Hagler (1989) 211 Cal.App.3d 1171, 1182; Scott v. Workers' Comp. Appeals Bd.
