(a) The appeal shall be heard and determined by the circuit court upon the issues raised by the notice of appeal and response according to the rules relating to the trial of civil actions, so far as applicable.

The commission may modify its findings and decision by reason of the additional evidence and shall file that evidence and any modifications, new findings, or decisions with the reviewing circuit court.
