Claim of Oberson v. Bureau of Ferry Aviation & Transportation

The claimant was terminated from his employment as a marine oiler after a physical altercation with his supervisor in January 1993. He sought workers' compensation benefits, claiming a compensable psychological injury from the altercation. A Workers’ Compensation Law Judge disallowed the claim due to the claimant's failure to timely notify the employer of his injury. The Workers’ Compensation Board affirmed this decision, which was subsequently affirmed on appeal. Although the employer had actual knowledge of the altercation and termination, there was no indication they had actual knowledge of a psychological injury stemming from the altercation until 1999, approximately six years later. The Board's determination that the employer did not have timely notice and was prejudiced by the delay was supported by substantial evidence.

KHIN LAY vs. SWEDA COMPANY LLC, ZURICH AMERICAN INSURANCE

The Workers' Compensation Appeals Board denied Khin Lay's petition for reconsideration. The Board adopted the findings of the Administrative Law Judge (WCJ), emphasizing the significant weight given to the WCJ's credibility determination. The applicant, Khin Lay, sought reconsideration after his claim was denied, likely based on findings that he was the initial aggressor in a workplace altercation. The WCJ's report, which the Board incorporated, detailed conflicting testimony regarding the altercation but ultimately found the applicant's actions met the standard for the initial aggressor defense, leading to the denial.

Claim of Bell v. Utica Corp.

Claimant sought workers' compensation benefits for neck and shoulder injuries sustained during a work-related altercation with a supervisor. The Workers’ Compensation Board reversed a WCLJ decision, concluding claimant's injuries stemmed from his willful intention to injure the supervisor and dismissed the claim. On appeal, the court found this determination improper, noting the absence of evidence for purely personal animosities and that initial aggression alone does not establish willful intent. The court emphasized that work-related altercations are generally compensable unless there's clear proof of a willful and deliberate intent to harm, beyond impulsive action. Consequently, the Board's decision was reversed, and the matter was remitted for further proceedings consistent with the court's findings.

Nitz v. Gusmer Corp.

Plaintiff was injured during a physical altercation in a trailer owned by his employer, Sandra Nitz. During the fight, he was pushed into stacked barrels, which in turn knocked him into a proportioner mixing machine manufactured by Gusmer Corporation, causing a cut on his arm. He sued Wallace Space Conditioning, Inc., the property owner, alleging Labor Law § 240 (1) and § 241 (6) violations, and Gusmer Corporation for strict products liability, breach of warranty, and negligence. The court determined that neither Labor Law provision was applicable as the injury was not elevation-related nor related to construction work. Furthermore, any alleged defect in the machine was not the proximate cause of the injury, but rather the altercation itself. The Supreme Court's order partially denying the defendants' motions for summary judgment was reversed, and summary judgment was granted to both defendants, dismissing the complaint.

JEHUDA KNOBLER vs. LOS ANGELES UNIFIED SCHOOL DISTRICT, SEDGWICK CLAIMS MANAGEMENT SERVICES

This case involves a teacher claiming workers' compensation for PTSD after a student altercation. The Board overturned the initial finding, now recognizing the PTSD as arising out of and occurring in the course of employment. However, they affirmed the finding that the applicant was the initial physical aggressor under Labor Code section 3600(a)(7). This disqualifies him from receiving compensation benefits due to his role in initiating the physical confrontation.

SCOTT M. M. RATHKE vs. LLOYD ELECTRIC, REDLAND INSURANCE COMPANY, GALLAGHER BASSETT SERVICES

This case involves a workers' compensation claim for injuries sustained during an altercation with a co-worker. The applicant alleged the co-worker initiated the physical assault, while the defendants argued the applicant was the initial aggressor and therefore ineligible for benefits. The Administrative Law Judge found the defense witness more credible and denied the applicant's claim, a decision upheld by the Workers' Compensation Appeals Board.

CHARLES THOMAS vs. LOS ANGELES COUNTY METROPOLITAN TRANSIT AUTHORITY

This case involves a bus driver injured during an altercation with a passenger. The Appeals Board reversed the initial ruling, finding the injury compensable because the applicant was not the initial physical aggressor. While the applicant's actions were unauthorized, they occurred in the course of employment as they stemmed from his duties dealing with the passenger. The Board also found sufficient evidence of injury beyond the applicant's testimony. The case is returned for further proceedings on all remaining issues.

James Lewis vs. Compton Unified School District, Hazelrigg Risk Management Services

The Workers' Compensation Appeals Board granted reconsideration, reversing a prior finding that James Lewis was not the initial physical aggressor in an altercation. The Board found that Lewis's actions, including throwing tools at a co-worker and attempting to move the co-worker's truck, initiated the physical confrontation. Consequently, Lewis's claim for injury benefits is barred under Labor Code section 3600(a)(7).

JULIAN YAC vs. NIETOS BROTHER ORPORATION, ZENITH INSURANCE COMPANY

The Workers' Compensation Appeals Board denied reconsideration in the case of Julian Yac. The Board adopted the WCJ's report, which found the applicant was the initial physical aggressor in an altercation with a customer, barring his claim. This determination was based on witness credibility and evidence of the applicant's confrontational actions, despite not causing immediate physical harm. The WCJ's credibility findings were given great weight, as per established case law.

RICHARD GALINDO vs. MV TRANSPORTATION, INC.; BROADSPIRE, a CRAWFORD COMPANY

This case concerns a bus driver who sustained a back injury after an altercation with a passenger. The employer denied the claim, asserting the employee was the initial physical aggressor, which would bar compensation. The Board reviewed videotape evidence and affirmed the WCJ's finding that the passenger's spitting and verbal threats constituted the initial physical aggression. Therefore, the employer failed to establish the exclusion under Labor Code section 3600(a)(7), and the injury is compensable.
