Defendant states that this view is contrary to that expressed in Pearson Candy Co. v. Waits, 27 Cal.2d 615, 619 [165 P.2d 674], that “the board’s orders . . . rest simply on an appeal to the moral obligation of the parties and are neither enforceable nor reviewable. [Citations.]” Defendant contends that since he would be under no duty to comply if the board ordered him to change his rates, his failure to secure approval of a change in rates would not render them invalid. This contention, however, overlooks the dual function of the War Labor Board. The Pearson case and other cases enunciating the same rule were concerned with directive orders of the board issued pursuant to its authority under the War Labor Disputes Act of 1943 (50 U.S.C.A. App. §§ 1501-1511) to issue orders designed to settle labor disputes brought before it. This power of the board to issue directive orders in eases of labor disputes was distinct from its power to approve or reject changes in wage rates under Executive Order No. 9250. In exercising the latter power the board did not order any*451thing; it merely approved or failed to approve suggested wage rate changes that were filed with it. It was the statute and the executive order, not a. directive of the board, that prohibited wage rate changes if approval was not granted. Any change in wage rates without such approval was ineffective and void. (Wernhardt v. Koenig, 60 F.Supp. 709; Kells v. Boutross, 184 Misc. 206 [53 N.Y.S.2d 734]; Claude S. Bennett, Inc., v. Bollinger, 72 Ga.App. 531 [34 S.E.2d 563].)
