MARK HOPKINS vs. COUNTY OF LOS ANGELES, INTERCARE INSURANCE SERVICES
The Workers' Compensation Appeals Board denied reconsideration of a decision that disallowed a defendant's attempt to offset an overpayment of disability indemnity from one workers' compensation case against liability in a separate, independent case. The Board affirmed the judge's reasoning, emphasizing that mutual mistake was not established and that crediting overpayments across distinct claims is impermissible. Despite the defendant's argument of oversight and an $8500 overpayment, the Board found no basis to deviate from established legal principles. The decision upholds the integrity of separate claim resolutions.
