Appellant brought this suit in the district court of Eayette county on the 28th day of November, 1919, for mandamus against appellee as tax collector of Austin county, compelling him to receive from appellant the sum of $1.75 in payment of her poll tax and to issue to her a receipt therefor that she might-be thereby qualified to participate and vote in the Democratic primary election to be held in the year 1920, as authorized by the act of the Thirty-Eifth Legislature of the State of Texas, passed at the fourth called session of that Legislature and published in the general laws of that session, pages 61-63.

Appellee filed his answer on December 6, 1919, consisting of general demurrer, general denial, and further answered admitting specifically and in detail all of the material allegations contained in plaintiff’s original petition, and set up the unconstitutionality of the act under which appellant claims the right to vote.

The trial was by the court without a jury and resulted in a judgment in favor of ap-pellee, sustaining the general demurrer to appellant’s petition, and against appellant, dismissing her petition on refusal to amend, and for cost of suit.

This judgment was appealed from, and the appeal submitted to this court on December 18, 1919, and on December 23, 1919, the controlling question in the case was certified to the Supreme Court.

The original opinion of the Supreme Court answering the certified question was filed on January 28, 1929 (218 S. W. 479). A motion for rehearing filed in that court was overruled on April 21, 1920 (221 S. W. 880).

The answer of the Supreme Court was certified to and filed in this court on May 18, 1920.

Erom the foregoing statement of the purpose of the suit and the progress of the litigation, it is apparent that this court cannot now, nor could at any time after the answer of the Supreme Court to the certified question was returned to this court, have rendered a judgment granting appellant the relief sought by her suit. The time in which the payment of a poll tax entitling plaintiff to vote in the primary elections held in 1920 had expired before the final determination by the Supreme Court of appellant’s right to demand the issuance to her of a poll tax receipt. All *189 of said elections have long since been held, and, if the appellee had authority to now issue a poll tax receipt which would have entitled appellant to vote in said election, it would be an idle and vain thing for this, court to now render a judgment compelling the appellee tax collector to issue such receipt. It would he equally vain- and idle for this court to now adjudge that appellant was entitled at the time she applied therefor to have the receipt issued, since the Supreme Court in answering the certified question so adjudged, and her right to vote in the future is now .protected by the recently adopted amendment to the Constitution of the United States.

[1] We think as the case now stands the proper judgment for this court to render is one dismissing the appeal, just as in a case in which the subject-matter of the suit has ceased to exist.

[2] In such cases the costs of the appeal are ordinarily adjudged against the appellant on the ground stated by Chief Justice Roberts in the case of Lacoste v. Duffy, 49 Tex. 767, 30 Am. Rep. 122, that—

“It has not been customary' [for an appellate court] to decide questions of importance after their decision has become useless, merely to ascertain who is liable for the cost. The amount of business of practical importance would forbid that the time of the court should be so occupied.”

[3] The reason on which this rule is based is not present in this case, because the Supreme Court has decided in this case that appellant was entitled to have the receipt issued to her. Appellee having, in the opinion of a majority of the Supreme Court, wrongfully refused to issue the receipt and thereby caused appellant to incur the cost of this litigation, should be required to pay all such costs.

As above indicated, the appeal will be dismissed and the costs adjudged against the appellee.

Dismissed.
