In a due process action involving the assertion of a prevailing wage violation, trial court's grant of summary judgment on the grounds that plaintiff failed to exhaust mandatory judicial remedies is reversed where: 1) there is no evidence in the record of administrative proceedings that possessed a judicial character and yielded a result adverse to plaintiff that could have been the subject of review in mandate; and 2) defendant offered no evidence that plaintiff failed to file a petition for relief in mandate even if the doctrine of exhaustion of judicial remedies were to apply.
