MARIA OCHOA vs. RANGERS DIE CASTING COMPANY, COMPWEST INSURANCE COMPANY

The Workers' Compensation Appeals Board (WCAB) granted reconsideration of a decision finding the applicant sustained injury to her respiratory system and psyche AOE/COE. The WCAB rescinded the decision and returned the case to the trial level, finding the medical opinions of Dr. Lipper and Dr. Curtis lacked substantiality. Specifically, the physicians failed to provide clear diagnoses, quantify exposures, or adequately explain causation. The Board noted contradictory testimony from the applicant's supervisor and insufficient evidence to support the initial findings.

ANA DE AYALA vs. AO-THE UNIVERSITY CORPORATION / CALIFORNIA STATE UNIVERSITY NORTHRIDGE

The Workers' Compensation Appeals Board granted reconsideration and reversed a prior ruling, finding the applicant sustained industrial injury to her neck. While the applicant testified to injuring her neck in a workplace incident and this was partially corroborated, the Board found insufficient evidence for other claimed injuries. The Board specifically disagreed with the administrative law judge's credibility assessment concerning the neck injury itself, relying on medical reports and testimony supporting the neck injury claim. The Board affirmed the denial of claims for all other alleged injuries, finding insufficient medical evidence to link them to the incident.

Miguel Mosqueda vs. City of Clearlake

Applicant Miguel Mosqueda sought reconsideration of a July 25, 2025 decision which found his injuries were not caused by the employer's serious and willful misconduct or violation of safety orders. Mosqueda, a maintenance worker, suffered catastrophic injuries, including paraplegia, after falling from a ladder while trimming a tree for the City of Clearlake. He contended that the employer violated several Cal. Code Regs., tit. 8 sections related to safety, training, and equipment. The Workers' Compensation Appeals Board, adopting the WCJ's report, denied the petition for reconsideration, concluding that the employer's actions did not constitute serious and willful misconduct and that no alleged safety violation was the proximate cause of the accident.

ROBERT SIEBURG vs. RONALD WOLFE & ASSOCIATES, STATE COMPENSATION INSURANCE FUND

The Workers' Compensation Appeals Board granted reconsideration, rescinded the original award, and returned the case for further development of the record. The Board found the findings of the administrative law judge regarding $97\%$ permanent disability and apportionment were not supported by substantial medical evidence. Specifically, the opinion of Dr. Kahmann was deemed deficient due to internal inconsistencies, lack of explanation for apportionment, and undefined work restrictions. The Board also found Dr. Basham's report did not meet the standard for substantial medical evidence regarding cognitive dysfunction.

PEDRO M. RODRIGUEZ vs. RALPHS GROCERY COMPANY

The applicant sought reconsideration of a denial of workers' compensation benefits, which was based on the finding that his claims were filed after notice of termination. The Board affirmed the denial, concluding that the applicant's job abandonment led to a termination prior to the filing of his claims. The Board also determined that the employer properly denied both the specific and cumulative trauma claims, thus negating a presumption of compensability.

TOK SUN SONG vs. CAFE PRINCE aka HWANG TAEJA, CALIFORNIA INDEMNITY INSURANCE COMPANY, GALLAGHER BASSETT SERVICES, INC.

This Workers' Compensation Appeals Board order dismisses Tok Sun Song's petition for reconsideration. The dismissal is based on two grounds: the petition was filed untimely, exceeding the statutory 25-day limit after the WCJ's decision. Additionally, the petition was not verified, and the applicant failed to cure this defect or provide a valid explanation within a reasonable time after notice. As these are jurisdictional defects, the Board lacked authority to consider the untimely and unverified petition.

PARDEEP SINGH vs. 7 ELEVEN, MITSUI SUMITOMO

The Workers' Compensation Appeals Board (WCAB) dismissed Pardee Singh's Petition for Reconsideration. The petition was deemed untimely because it was filed on August 28, 2019, which was after the jurisdictional deadline of August 26, 2019. This deadline was calculated from the service date of an Order Allowing Costs on August 1, 2019. The WCAB clarified that for a petition to be timely, it must be *received* by the board within the statutory period, not merely mailed.

ANELLA MILES vs. RALPHS GROCERY COMPANY, administered by SEDGWICK CLAIMS MANAGEMENT SERVICES, INC.

The Workers' Compensation Appeals Board (WCAB) granted the defendant's petition for removal, rescinding the original order. The WCAB found the original order, which replaced a Qualified Medical Examiner (QME) for alleged unavailability for deposition, was improperly issued due to a lack of a proper record. The WCAB emphasized that a complete record, including stipulations and admitted evidence, is essential for decisions. Therefore, the case was returned to the WCJ for further proceedings with a proper evidentiary record.
