"* * * All official acts of a school board relative to motions or resolutions passed at board meetings become effective at the time of such passage unless otherwise expressly provided therein." See Hanson v. Harrisburg Ind. School District, 86 S.D. 42, 56, 190 N.W.2d 843, 851. While we regard our Middle Creek School District No. 18 decision, supra, construing the statutes involved here as controlling, attention is called to an opinion involving a statute requiring an appeal from an award of a Workmen's Compensation Board to be filed within twenty days of its rendition where the court held the date of the award was the date of its rendition and the appeal was not timely taken.
