This was an action by the state, on the relation of Ernest T. Bynum, Bank Commissioner, against T. C. Greer, court clerk of Tillman county, seeking a writ of mandamus requiring the defendant to number and file a petition tendered him for filing, and to issue a summons in accordance with the praecipe sought to be filed, in a cause wherein the state on the relation of the said Bank Commissioner was plaintiff, and one R. Dugan was defendant, without requiring the plaintiff to make a cash deposit, or cost bond as required of other litigants. The trial court denied the writ, and the plaintiff has appealed.

The plaintiff in error has served and filed its brief in accordance with the rules and orders of this court, but the defendant in error has neither filed a brief nor offered any excuse for his failure to do so. Under these circumstances, this court will not search the record in an effort to find some theory upon which the judgment of the trial court may be sustained, but may, where the aitthorities in the brief filed appear reasonably to sustain the assignments of error, reverse the cause in accordance with the prayer of the petition in error. Chicago, R. I. & P. Ry. Co. v. Weaver, 67 Okla. 293, 171 Pac. 34; Godfrey v. Pounds, 86 Okla. 76, 206 Pac. 516: In re Estate of Enos Nichols, 86 Okla. 181, 207 Pac. 93.

However, we have examined the record, as well as the brief of the plaintiff in error, and the authorities cited therein, and are convinced that the court erred in denying the plaintiff the relief sought. Therefore, the judgment of the trial court is reversed, and the cause remanded, with directions to grant the writ of mandamus as prayed for.
