LORENZO TOSCANO CORONA vs. KOOSHAREM, doing business as SELECT STAFFING, CALIFORNIA INSURANCE GUARANTEE ASSOCIATION (CIGA), ULLICO CASUALTY INSURANCE COMPANY, ACE AMERICAN INSURANCE COMPANY, RSI HOME PRODUCTS, TRAVELERS PROPERTY CASUALTY COMPANY OF AMERICA, LIBERTY MUTUAL INSURANCE COMPANY

This case involves a dispute over workers' compensation coverage where applicant Lorenzo Toscano Corona was injured, allegedly while employed through a staff leasing arrangement between Koosharem (Select Staffing) and RSI Home Products. The Appeals Board granted reconsideration to address arguments by ACE American Insurance Company and Travelers Property Casualty Company that their policies excluded coverage for the applicant. The Board rescinded the prior decision due to the arbitrator's failure to adequately document the proceedings and admitted exhibits as required by law. The matter is returned to the arbitrator to create a proper record and evaluate whether ACE and Travelers' policies contained valid exclusions for the applicant's injuries, considering relevant insurance code provisions and endorsements.
