The respondent has not appeared nor filed a brief in this appeal. The court may, therefore, reverse the order upon the procedural ground pursuant to sec. (Eule) 251.57, Stats.

The appellant has requested the court to consider the case upon its merits and reverse the order. We are not persuaded the request should be granted. It appears that there may be meritorious arguments that sec. 344.04 (2), Stats., is not limited solely to cases where undue hardship is alleged. In any event, we are of the opinion that the issues should be briefed and argued on both sides before the court restricts the section as contended by the administrator.

We therefore reverse under sec. (Eule) 251.57, Stats., and not upon the merits.

*293 By the Court. — Order overruling the demurrer and restraining the administrator of the division of motor vehicles is reversed with directions to enter an order sustaining the demurrer, quashing the restraining order and to enter judgment dismissing the petition.
