The trial court determined that an injured worker had been assigned no valid impairment rating upon which to base impairment income benefits under the Texas Workers' Compensation Act. The absence of a valid impairment rating that had been submitted to the agency does not deprive a reviewing court of subject matter jurisdiction. The Workers' Compensation Act permits a court to remand to the Workers' Compensation Division if it decides that the worker has no valid impairment rating. The case is reversed and remanded to the trial court with instructions that the court remand the case to the division. Texas Supreme Court, No. 10-0319, 11-16-2012.
