C.R.S. § 8-43-308

Upon hearing the action, the court of appeals may affirm or set aside such order, but only upon the following grounds: That the findings of fact are not sufficient to permit appellate review; that conflicts in the evidence are not resolved in the record; that the findings of fact are not supported by the evidence; that the findings of fact do not support the order; or that the award or denial of benefits is not supported by applicable law. If the findings of fact entered by the director or administrative law judge are supported by substantial evidence, they shall not be altered by the court of appeals.
