Every formal order of the commission shall be based upon the facts of record. However, the commission may, without a hearing, issue an order approving any settlement supported by all the parties of record in a proceeding, including a compromise settlement. Every order entered pursuant to a hearing must state the commission's findings, the basis of its findings and conclusions, together with its decision. These orders shall be entered of record and a copy of them shall be served on all parties of record in the proceeding.
