JAIME LLAMAS vs. CITY OF ANAHEIM, CITY OF DOWNEY

Applicant Jaime Llamas, a police officer, sustained a cumulative brain injury (cancer) while employed by the City of Downey and the City of Anaheim. The WCJ found both employers jointly and severally liable. Defendant City of Downey sought reconsideration, challenging the last injurious exposure and their liability for temporary disability. The Appeals Board granted reconsideration, rescinded the original Findings and Award, and substituted new findings. The Board confirmed the cumulative injury, clarified employment periods, affirmed the industrial presumption for both employers, established a specific liability period (December 21, 2016, through December 21, 2017) based on medical evidence of latency, and deferred issues of contribution between the employers.

JASON POIRIER vs. CITY OF MENLO PARK, Permissibly Self-Insured; administered by INNOVATIVE CLAIMS SOLUTIONS, CITY OF BRISBANE; Permissibly Self-Insured; administered by INNOVATIVE CLAIMS SOLUTIONS

The Workers' Compensation Appeals Board granted reconsideration, reversing the trial judge's decision that denied Jason Poirier's claim for kidney cancer benefits. The Board found that the City of Menlo Park failed to rebut the presumption under Labor Code section 3212.1 that Poirier's cancer was industrially caused. Crucially, the Board ruled that Poirier's prior employment with the City of Brisbane could be combined with his Menlo Park employment to satisfy the minimum latency period for cancer causation, a point the trial judge had incorrectly excluded. Consequently, the Board amended the findings to establish that Poirier sustained an industrial injury and returned the case for benefit determination.

ROLANDO RENTERIA vs. CITY OF DOWNEY

The Workers' Compensation Appeals Board denied the City of Downey's petition for reconsideration. The Board upheld the finding that police officer Rolando Renteria sustained a compensable injury to his right thumb while weightlifting at home. This was because the WCJ found the off-duty exercise to be a reasonable expectancy of employment, citing Renteria's role as a breacher on the entry team and participation in strength-based training and fitness tests. The Board deferred to the WCJ's credibility findings regarding Renteria's belief that his employer expected such fitness maintenance.

KASSONDRA MORELAND vs. CITY OF UNION CITY, CITY OF SUNNYVALE

This case concerns contribution between two employers for a cumulative trauma injury. The Workers' Compensation Appeals Board (WCAB) amended an arbitrator's decision regarding the date of injury. The WCAB found the date of injury to be December 5, 2005, when the applicant first suffered a wage loss due to medical restrictions. This decision shifts liability for contribution to the employer who employed the applicant during the year preceding this date. A dissenting commissioner argued the date of injury should be later, correlating with the applicant's surgery and receipt of temporary disability benefits.

NORMAN WESEMAN vs. CITY OF CATHEDRAL CITY, Permissibly Self-Insured, SUPERIOR READY MIX, Permissibly Self-Insured

This case consolidates three workers' compensation claims for applicant Norman Weseman. The Appeals Board affirmed findings that claims against Superior Ready Mix (ADJ9531390) and the City of Cathedral City (ADJ9352398) for heart/hypertension and firefighter injuries were not barred by the statute of limitations. However, the Board rescinded a finding regarding a specific injury claim against the City of Cathedral City (ADJ9352393) due to insufficient medical evidence on the injury's manifestation date and returned it for further proceedings. The core legal issue concerns when the statute of limitations begins to run for latent industrial injuries.

DAVID ANTHONY WILSON vs. CITY OF POMONA; ADMINSURE, CITY OF LOS ANGELES

This Workers' Compensation Appeals Board decision addresses a clerical error found in its previous decision from May 15, 2025. The original decision erroneously included Joseph V. Capurro, Commissioner, as a panel member. The current order formally corrects this error by removing Commissioner Capurro's name, without the need for reconsideration. The underlying case involved David Anthony Wilson as the applicant against the City of Pomona, AdminSure, and the City of Los Angeles, with adjudication numbers ADJ11171496 and ADJ3047881, originating from the Pomona District Office. The original May 15, 2025 decision was an Opinion and Order Dismissing Petition For Removal, issued after the petitioner withdrew their request for removal.

RICHARD JOHNSON vs. CITY OF SOUTH SAN FRANCISCO, CITY OF PACIFICA

This case concerns the award of appellate costs to the City of Pacifica. The Court of Appeal previously affirmed a decision in Pacifica's favor and ordered the City of South San Francisco (CSSF) to bear Pacifica's costs. Pacifica subsequently submitted a verified petition for costs totaling $1,425.00, which included electronic filing and paper copy expenses. The Workers' Compensation Appeals Board found Pacifica's requested costs reasonable and awarded them against CSSF.

Samuel Turco vs. CITY OF OAKLAND, Permissibly Self-Insured

The Workers' Compensation Appeals Board granted the City of Oakland's petition for reconsideration, overturning a prior finding that Samuel Turco's cumulative trauma heart injury claim was not time-barred. The Board determined that Turco knew or should have known his disability was industrially caused by no later than February 10, 2007, when he sought legal advice and filed a claim related to his 2002 heart attack. Since his claim against the City of Oakland was filed in April 2008, it was deemed barred by the one-year statute of limitations under Labor Code section 5405. Consequently, Turco's claim against the City of Oakland was dismissed.

LARRY MYERS vs. CITY OF SALINAS

In this workers' compensation case, the defendant City of Salinas sought reconsideration of an award granting the applicant, a police captain, 84% permanent disability and lifelong pension. The defendant argued for apportionment of disability to non-industrial causes, disputing the applicability of the Labor Code section 3213.2 "duty belt" presumption. The Workers' Compensation Appeals Board denied reconsideration, finding the defendant had previously stipulated to the presumption's applicability and that the applicant independently qualified for it based on his employment history and duty belt usage.

This case involves a petition for reconsideration filed by the defendants, City of Cathedral City and Superior Ready Mix. The Workers' Compensation Appeals Board (WCAB) has granted this petition. Reconsideration was granted due to statutory time constraints and the need for further study of the factual and legal issues.

All future correspondence related to the petition must be filed directly with the WCAB Commissioners, not district offices or e-filed.
