German Renteria Pina vs. Miguel Diaz dba Brother Landscape, Da Vinci Schools

German Renteria Pina, the applicant, sustained a specific injury while employed by Miguel Diaz dba Brother Landscape, an uninsured entity. Da Vinci Schools, a permissibly self-insured entity, was also named as a defendant. The Uninsured Employers Benefits Trust Fund (UEBTF) petitioned for reconsideration of a WCJ's finding that Pina was an employee of Diaz and not Da Vinci, arguing errors in employment burden of proof and insufficient evidence. The Workers' Compensation Appeals Board granted the petition, rescinded the prior Findings of Fact and Order, and returned the matter to the trial level for further proceedings. This decision was made because the record was deemed incomplete to adequately determine Diaz's independent contractor status or the applicability of licensing requirements.

JAIRO RAMOS vs. JTS JOSE TREE SERVICE, INC., JOSE MIGUEL SOTO, DANIEL SOTO, UNINSURED EMPLOYERS BENEFITS TRUST FUND

This case involves a workers' compensation claim where the applicant sustained an admitted industrial injury. The primary issue is determining the identity of the employer(s), with allegations of joint ownership/operation between JTS Jose Tree Service, Inc., Jose Miguel Soto, and Daniel Soto. Jose Soto's petition for reconsideration was dismissed as untimely and procedurally deficient. Daniel Soto's petition was granted because the original findings lacked evidentiary support and the record required further development regarding employment status and potential licensing issues. The case is remanded to the trial level for further proceedings.

GEORGE DIAZ vs. REYES MASONRY CONTRACTORS, INC., CITATION INSURANCE COMPANY, GENERAL REINSURANCE, INTERCARE, SUBSEQUENT INJURIES BENEFITS TRUST FUND

The Workers' Compensation Appeals Board denied George Diaz's petition for reconsideration, affirming the administrative law judge's award of 93.75% permanent disability. The judge apportioned 30% of Diaz's orthopedic disability to prior injuries, relying on medical evidence of degenerative changes aggravated by the 1992 industrial injury. Diaz's arguments for 100% permanent disability due to total disability or loss of use of both hands were rejected due to insufficient medical evidence. The Board found the apportionment was supported by substantial medical evidence and did not qualify for an unapportioned award under the *Hikida* precedent.

ROBERTO RAMIREZ (Deceased); MARIA GUADALUPE DIAZ de RAMIREZ, Guardian ad Litem for MARIA LINA RAMIREZ DIAZ, vs. VISTA PAINT CORPORATION, Permissibly Self-Insured,

This Workers' Compensation Appeals Board decision grants reconsideration and returns the case to the trial level for further proceedings. While the WCJ correctly found the daughter was partially dependent, the Board noted an incomplete record regarding the wife's dependency status and potential eligibility under Labor Code section 3501(b). The Board also found the issue of attorney fees was not decided. Consequently, the matter is remanded for determination of the wife's dependency, the correct death benefit amount, and attorney fees, or for clarification on why these issues were not previously addressed.

JESUS HERNANDEZ vs. WARNER BROTHERS STUDIOS

The Workers' Compensation Appeals Board (WCAB) denied Warner Brothers Studios' petition for removal in the case of Jesus Hernandez. Removal is an extraordinary remedy granted only when substantial prejudice or irreparable harm will result from denial and reconsideration is inadequate. The WCAB found that Warner Brothers failed to demonstrate either of these conditions based on the WCJ's report. Therefore, the petition for removal was denied.

GENOVEVA AYALA vs. WARNER BROTHERS

This case involves Genoveva Ayala's workers' compensation claims against Warner Brothers for multiple injuries. The Administrative Law Judge (WCJ) found some injuries to be established but excluded applicant's medical evidence regarding neurological and internal injuries due to alleged procedural violations. The Appeals Board granted reconsideration, finding that the applicant should have an opportunity to obtain admissible medical reports through the Qualified Medical Evaluator (QME) process, as defendants allegedly interfered with this process. Consequently, the issue of neurological and internal injuries is deferred for further evaluation.
