Modifies provisions related to workers' compensation administrative law judges

HB 123 updates Missouri's workers' compensation rules for permanent total disability benefits. It sets specific weekly compensation rates based on injury dates (e.g., 66.67% of average weekly earnings, capped at 70%-105% of state average wage) and adds new provisions for toxic exposure injuries. For toxic exposure cases, it provides 200% of state average weekly wage for 100 weeks, with mesothelioma cases offering an additional 300% for 212 weeks (expiring 2038) if employers elect liability. These changes directly affect injured workers, their dependents, and employers handling claims for permanent total disability or death due to occupational injuries.
