On an appeal from the Board of Railroad Commissioners the court is primarily required to determine the lawfulness of the order appealed from. State v. Great Northern R. Co. 56 N.D. 822, 219 NW 295. Rate-making commissions sometimes consider the "bare-bones" value of the property and add a going-concern value as a separate item and sometimes charge it in with other items of cost and expenses and make no separate allowance.

The lawfulness, under the decisions, means that the railroad commissioners had jurisdiction to render the judgment or order and that it was not unreasonable or arbitrary. State v. Great Northern R. Co. 56 N.D. 822, 219 N.W. 295; Lillegard v. Great Northern R. Co. 66 N.D. 541, 267 N.W. 723; Chicago R. Co. v. Commerce Commission, 336 Ill. 51, 167 N.E. 840, 67 A.L.R. 938. See extensive notes in 67 A.L.R. page 957.
