Victoria Lee vs. Subsequent Injuries Benefits Trust Fund

The Subsequent Injuries Benefits Trust Fund (SIBTF) sought reconsideration of a December 4, 2024 Findings and Order, arguing that the WCJ incorrectly failed to apportion the industrial injury to preexisting disability when determining if Victoria Lee met the 35% permanent disability eligibility threshold for SIBTF benefits. The Appeals Board denied the petition, adopting the WCJ's Report and Recommendation. The Board reiterated that, based on prior case law, including Bookout v. Workers' Comp. Appeals Bd. and subsequent panel decisions, apportionment is excluded when calculating whether an applicant meets the 35% threshold for SIBTF benefits under Labor Code Section 4751.

KAREN WHISNANT vs. SUBSEQUENT INJURIES BENEFITS TRUST FUND

The Workers' Compensation Appeals Board granted reconsideration to address whether apportionment applies when calculating the subsequent permanent disability threshold for SIBTF benefits. Applicant Karen Whisnant's eligibility for SIBTF benefits hinged on this interpretation, with the WCJ initially finding her eligible based on a 42% disability without apportionment. The Board affirmed the WCJ's April 5, 2022 Findings of Fact but clarified that apportionment is not considered when determining the 5% or 35% SIBTF eligibility threshold, citing precedents like Bookout v. Workers' Comp. Appeals Bd. Consequently, the Board's decision ensures that the applicant's subsequent injury rating of 42% (unapportioned) qualifies her for benefits.

JUAN MONDRAGON vs. SUBSEQUENT INJURIES BENEFITS TRUST FUND

The Workers' Compensation Appeals Board granted reconsideration, rescinded the prior award, and remanded for further proceedings, primarily due to the WCJ's failure to adequately document the issues in controversy. The Board clarified that for Subsequent Injuries Benefits Trust Fund (SIBTF) claims, pre-existing and subsequent disabilities should be added together, not combined using the Combined Values Chart, citing *Bookout*. The Board also noted that the issue of commuting attorney's fees in SIBTF cases was not disputed and would be amended accordingly.

JAMES KWASIGROCH vs. SUBSEQUENT INJURIES BENEFIT TRUST FUND OF CALIFORNIA

This case concerns the calculation of combined permanent disability for Subsequent Injuries Benefit Trust Fund (SIBTF) benefits. The applicant, James Kwasigroch, received awards for a prior disability of 63% and a subsequent disability of 74%. The central dispute was whether to add these percentages directly or use a Combined Values Chart (CVC) as the trial judge did. The Appeals Board reversed the trial judge's decision, holding that non-overlapping prior and subsequent disabilities should be added based on the precedent set in *Bookout v. Workers' Comp. Appeals Bd.* This resulted in a finding of 100% combined permanent disability and an adjustment to attorney's fees.

JOHN WADE vs. SUBSEQUENT INJURIES BENEFITS TRUST FUND

The Workers' Compensation Appeals Board rescinded a previous award and remanded the case for further proceedings concerning the applicant's cumulative trauma injury. The primary issues involve how prior and subsequent disabilities should be combined for SIBTF benefits and whether SIBTF is entitled to a credit against the applicant's disability pension. The Board requires further development of the record to determine the extent of overlapping disabilities and the basis for the applicant's pension. The issue of permanent total disability is deferred pending these further proceedings.

RICHARD GILLISPIE vs. PLASTECH, SUBSEQUENT INJURIES BENEFITS TRUST FUND

The Subsequent Injuries Benefits Trust Fund (SIBTF) appealed an award of benefits to an applicant with a pre-existing disability, arguing a subsequent industrial back injury did not cause pathology in the opposite leg as required by statute. The Appeals Board affirmed the award, finding that Labor Code section 4751 only requires the subsequent injury to "affect" the opposite member, not necessarily cause direct pathology. Evidence showed the applicant's low back injury caused verified radiculopathy and impaired leg function, meeting the statutory requirement. The Board found SIBTF's legal arguments unpersuasive and the WCJ's findings supported by substantial evidence.

BARTON LEWIS vs. COUNTY OF SANTA CLARA, SUBSEQUENT INJURIES BENEFITS TRUST FUND (SIBTF)

This case concerns the Subsequent Injuries Benefits Trust Fund (SIBF) liability for applicant Barton Lewis, who suffered multiple industrial injuries. The SIBF contested the applicant's eligibility, arguing he did not meet the statutory thresholds for benefits. The Board affirmed the Administrative Law Judge's decision, finding the applicant met the 35% permanent disability threshold under Labor Code section 4751 based on the February 5, 2003 injury alone, without apportionment. This decision allows the applicant to receive benefits from the SIBF.

Richard Todd, Applicant vs. Subsequent Injuries Benefits Trust Fund

The Appeals Board, in an en banc decision, held that when determining the combined permanent disability for Subsequent Injuries Benefits Trust Fund (SIBTF) liability under Labor Code section 4751, prior and subsequent permanent disabilities are to be added to the extent they do not overlap, rather than combined using the Combined Values Chart (CVC).

Kenneth Evanoff vs. CITY OF LOS ANGELES, SUBSEQUENT INJURIES BENEFITS TRUST FUND

This case involves an applicant seeking reconsideration of a workers' compensation award. The applicant, previously awarded 96% permanent disability for a 2007 injury, suffered a subsequent injury in 2012 resulting in prostate cancer. The initial award used the Combined Values Chart to calculate the combined disability at 98%, entitling him to benefits from the Subsequent Injuries Benefits Trust Fund (SIBTF). The applicant argues the trial judge erred by using the Combined Values Chart and seeks to simply add the disability percentages, leading to a 100% combined disability. The Board granted reconsideration, finding that in the absence of overlapping disabilities, the disabilities should be added, entitling the applicant to a 100% permanent disability rating and remanding for a new award.
