ROSE SANTANA vs. STANFORD UNIVERSITY, ZURICH AMERICAN INSURANCE COMPANY, CIGA, SEDGWICK CLAIMS MANAGEMENT SERVICES, INC., RELIANCE INSURANCE COMPANY

In this workers' compensation case, CIGA sought reimbursement for benefits paid, arguing two cumulative trauma injuries were actually one and Zurich was liable. The Appeals Board affirmed the prior denial of CIGA's claim, finding CIGA was judicially estopped from disputing the existence of two distinct cumulative trauma injuries after previously stipulating to them. CIGA also failed to present sufficient medical evidence to prove that both injuries contributed to the need for temporary disability or medical treatment. Therefore, the arbitrator's original decision denying CIGA's petition for contribution/reimbursement was upheld.
